The Deadly Toll of Abortion by Amateurs
By DENISE GRADY, The New York Times, June 2, 2009

BEREGA, Tanzania — A handwritten ledger at the hospital tells a grim story. For the month of January, 17 of the 31 minor surgical procedures here were done to repair the results of “incomplete abortions.” A few may have been miscarriages, but most were botched operations by untrained, clumsy hands.

Abortion is illegal in Tanzania (except to save the mother’s life or health), so women and girls turn to amateurs, who may dose them with herbs or other concoctions, pummel their bellies or insert objects vaginally. Infections, bleeding and punctures of the uterus or bowel can result, and can be fatal. Doctors treating women after these bungled attempts sometimes have no choice but to remove the uterus.

Pregnancy and childbirth are among the greatest dangers that women face in Africa, which has the world’s highest rates of maternal mortality — at least 100 times those in developed countries. Abortion accounts for a significant part of the death toll.

Observatory: Evolving Mosquitoes in the Galapágos
By HENRY FOUNTAIN, The New York Times, June 2, 2009

The animals of the Galapágos have been studied extensively since the days of Darwin and his finches. But there’s been less scrutiny of some of the archipelago’s insects, including mosquitoes.

Now, a paper in The Proceedings of the National Academy of Sciences, by scientists from the University of Leeds, the Zoological Society of London and Galapágos National Park, sheds light on the black salt marsh mosquito, Aedes taerniorhynchus. Since it is the only mosquito found throughout the archipelago, the findings raise concerns about the impact of mosquito-borne diseases.

Well: Better Running Through Walking
By TARA PARKER-POPE, The New York Times, June 2, 2009

I am more couch potato than runner. But not long ago, I decided to get myself into shape to run in the New York City Marathon, on Nov. 1, just 152 days from now. (Not that I’m counting.)

To train for my first marathon, I’m using the “run-walk” method, popularized by the distance coach Jeff Galloway, a member of the 1972 Olympic team. When I mentioned this to a colleague who runs, she snickered — a common reaction among purists.

But after interviewing several people who have used the method, I’m convinced that those of us run-walking the marathon will have the last laugh.

Contrary to what you might think, the technique doesn’t mean walking when you’re tired; it means taking brief walk breaks when you’re not.

Scientist at Work: Viktor Deak
Where Art and Paleontology Intersect, Fossils Become Faces

By DONALD G. McNEIL Jr., The New York Times, June 2, 2009

For his first date with a fellow art student, Viktor Deak suggested “Bodies,” the exhibit of flayed and plasticized humans.

She said yes, even though she had already seen it. He thought that was promising. But it was dinner afterward that convinced him this was the real thing.

“Any woman who could go to ‘Bodies’ with me and then eat a steak,” he said, “and still be dainty and fun and all, was a girl I could be with forever.”

Mr. Deak (pronounced DAY-ahk) and Xochitl Gomez were married at the Bronx Zoo, in the gorilla grotto. Which makes sense, given how much time they spend there. He brings the camera, she totes the big looking glass.

“They know it’s a mirror,” he said of the zoo’s gorilla family. “They come up, make faces, check out their teeth. I’ve gotten some really great shots.”

His interest in gorilla grimaces, like his interest in displays of dissected flesh, is professional. Mr. Deak, 32, is one of the world’s leading paleoartists. If you find yourself face to face in a museum with Homo habilis, Australopithecus afarensis or Paranthropus boisei, you may be looking at his work.

Essay: Wisdom in a Cleric’s Garb; Why Not a Lab Coat Too?
By DENNIS OVERBYE, The New York Times, June 2, 2009

There is a warm fuzzy moment near the end of the movie “Angels & Demons,” starring Tom Hanks and directed by Ron Howard.

Mr. Hanks as the Harvard symbologist Robert Langdon has just exposed the archvillain who was threatening to blow up the Vatican with antimatter stolen from a particle collider. A Catholic cardinal who has been giving him a hard time all through the movie and has suddenly turned twinkly-eyed says a small prayer thanking God for sending someone to save them.

Mr. Hanks replies that he doesn’t think he was “sent.”

Of course he was, he just doesn’t know it, the priest says gently. Mr. Hanks, taken aback, smiles in his classic sheepish way. Suddenly he is not so sure.

This may seem like a happy ending. Faith and science reconciled or at least holding their fire in the face of mystery. But for me that moment ruined what had otherwise been a pleasant two hours on a rainy afternoon. It crystallized what is wrong with the entire way that popular culture regards science. Scientists and academics are smart, but religious leaders are wise.

In a Time of Quotas, a Quiet Pose in Defiance
By BARRON H. LERNER, The New York Times, May 26, 2009

As a Jewish physician practicing medicine in 2009, I hardly ever pay attention to my religious affiliation.

But in the years before World War II, at my institution and at other medical schools, Judaism was very much on people’s minds. Informal quotas limited the numbers of Jewish medical students and physicians.

Within hospital walls, some non-Jewish physicians supported the quotas and others opposed them. An untold story from Columbia’s Neurological Institute demonstrates an ingenious attempt by one physician to thwart what he believed was an unjust policy.

Autopsies of War Dead Reveal Ways to Save Others
By DENISE GRADY, The New York Times, May 26, 2009

Within an hour after the bodies arrive in their flag-draped coffins at Dover Air Force Base, they go through a process that has never been used on the dead from any other war.

Since 2004, every service man and woman killed in Iraq or Afghanistan has been given a CT scan, and since 2001, when the fighting began in Afghanistan, all have had autopsies, performed by pathologists in the Armed Forces Medical Examiner System. In previous wars, autopsies on people killed in combat were uncommon, and scans were never done.

The combined procedures have yielded a wealth of details about injuries from bullets, blasts, shrapnel and burns — information that has revealed deficiencies in body armor and vehicle shielding and led to improvements in helmets and medical equipment used on the battlefield.

German Fossil Found to Be Early Primate
By JOHN NOBLE WILFORD, The New York Times, May 16, 2009

Fossil remains of a 47-million-year-old animal, found years ago in Germany, have been analyzed more thoroughly and determined to be an extremely early primate close to the emergence of the evolutionary branch leading to monkeys, apes and humans, scientists said in interviews this week.

Described as the “most complete fossil primate ever discovered,” the specimen is a juvenile female the size of a small monkey. Only the left lower limb is missing, and the preservation is so remarkable that impressions of fur and the soft body outline are still clear. The animal’s last meal, of fruit and leaves, remained in the stomach cavity.

In an article to be published on Tuesday in PLoS One, an online scientific journal, an international team of scientists will report that this extraordinary fossil could be a “stem group” from which higher primates evolved, “but we are not advocating this.”

Chemicals in Dragon’s Glands Stir Venom Debate
By CARL ZIMMER, The New York Times, May 19, 2009

The Komodo dragon is already a terrifying beast. Measuring up to 10 feet long, it is the world’s largest lizard. It delivers a devastating bite with its long, serrated teeth, attacking prey as big as water buffaloes.

But in a provocative paper to be published this week, an international team of scientists argues that the Komodo dragon is even more impressive. They claim that the lizards use a potent venom to bring down their victims.

Vermont Acts to Make Drug Makers’ Gifts Public
By NATASHA SINGER, The New York Times, May 20, 2009

Cracking down on medical industry payments to doctors, the Vermont legislature has passed a law requiring drug and device makers to publicly disclose all money given to physicians and other health care providers, naming names and listing dollar amounts.

The law, scheduled to take effect on July 1, is believed to be the most stringent state effort to regulate the marketing of medical products to doctors. It would also ban nearly all industry gifts, including meals, to doctors, nurses, medical staff, pharmacists, health plan administrators and health care facilities.

Ancient Figurine of Voluptuous Woman Is Found
By JOHN NOBLE WILFORD, The New York Times, May 14, 2009

No one would mistake the Stone Age ivory carving for a Venus de Milo. The voluptuous woman depicted is, to say the least, earthier, with huge, projecting breasts and sexually explicit genitalia.

Nicholas J. Conard, an archaeologist at Tubingen University in Germany, who found the small carving in a cave last year, says it is at least 35,000 years old, “one of the oldest known examples of figurative art” in the world. It is about 5,000 years older than some other so-called Venus artifacts made by early populations of Homo sapiens in Europe.

Plugging Holes in the Science of Forensics
By HENRY FOUNTAIN, The New York Times, May 12, 2009

It was time, the panel of experts said, to put more science in forensic science.

A report in February by a committee of the National Academy of Sciences found “serious problems” with much of the work performed by crime laboratories in the United States. Recent incidents of faulty evidence analysis — including the case of an Oregon lawyer who was arrested by the F.B.I. after the 2004 Madrid terrorist bombings based on fingerprint identification that turned out to be wrong — were just high-profile examples of wider deficiencies, the committee said. Crime labs were overworked, there were few certification programs for investigators and technicians, and the entire field suffered from a lack of oversight.

But perhaps the most damning conclusion was that many forensic disciplines — including analysis of fingerprints, bite marks and the striations and indentations left by a pry bar or a gun’s firing mechanism — were not grounded in the kind of rigorous, peer-reviewed research that is the hallmark of classic science. DNA analysis was an exception, the report noted, in that it had been studied extensively. But many other investigative tests, the report said, “have never been exposed to stringent scientific scrutiny.”

While some forensic experts took issue with that conclusion, many welcomed it. And some scientists are working on just the kind of research necessary to improve the field. They are refining software and studying human decision-making to improve an important aspect of much forensic science — the ability to recognize and compare patterns.

Out-of-Wedlock Birthrates Are Soaring, U.S. Reports
By GARDINER HARRIS, The New York Times, May 13, 2009

WASHINGTON — Unmarried mothers gave birth to 4 out of every 10 babies born in the United States in 2007, a share that is increasing rapidly both here and abroad, according to government figures released Wednesday.

Before 1970, most unmarried mothers were teenagers. But in recent years the birthrate among unmarried women in their 20s and 30s has soared — rising 34 percent since 2002, for example, in women ages 30 to 34. In 2007, women in their 20s had 60 percent of all babies born out of wedlock, teenagers had 23 percent and women 30 and older had 17 percent.

Much of the increase in unmarried births has occurred among parents who are living together but are not married, cohabitation arrangements that tend to be less stable than marriages, studies show.

Well: How Hospitals Treat Same-Sex Couples
by Tara Parker-Pope, The New York Times, May 12, 2009

During a medical emergency, a patient’s husband, wife, parents or other family members often are close by, overseeing treatment, making medical decisions and keeping vigil at the bedside.

But what happens if the hospital won’t allow you to stay with your partner or child?

That’s the challenge many same-sex couples face during health care emergencies when hospital security personnel, administrators and even doctors and nurses exclude them from a patient’s room because they aren’t “real” family members. The issue is addressed in a new report from The Human Rights Campaign Foundation, a gay, lesbian, bisexual and transgender civil rights group, and the Gay and Lesbian Medical Association. The groups have created a Healthcare Equality Index for hospitals that focuses on five key areas: patient rights, visitation, decision-making, cultural competency training and employment policies and benefits.

This year, 166 facilities across the country agreed to participate in the report, about twice as many as last year. The group says nearly 75 percent of the hospitals have policies to protect their patients from discrimination on the basis of sexual orientation. However, sometimes the policies aren’t correctly implemented by hospital workers. Some examples of unfair treatment of gay couples cited by the group include:

Well: Worry? Relax? Buy Face Mask? Answers on Flu
By TARA PARKER-POPE, The New York Times, May 5, 2009

Confused about swine flu? It’s no wonder, with all the seemingly mixed messages coming out of health agencies and news organizations.

Last week, the World Health Organization raised the alert level for the virus, whose formal name is H1N1, indicating that a “pandemic is imminent.” Now, health officials report that although the virus is widespread, most cases seem to be mild. People are being told not to panic, but schools in some communities remain closed.

It’s good news that the imminent threat appears to be abating, but questions remain about the virus and whether it will re-emerge in the Southern Hemisphere or back in North America next fall. Here are some answers.

A Battle to Preserve a Visionary’s Bold Failure
By WILLIAM J. BROAD, The New York Times, May 5, 2009

In 1901, Nikola Tesla began work on a global system of giant towers meant to relay through the air not only news, stock reports and even pictures but also, unbeknown to investors such as J. Pierpont Morgan, free electricity for one and all.

It was the inventor’s biggest project, and his most audacious.

The first tower rose on rural Long Island and, by 1903, stood more than 18 stories tall. One midsummer night, it emitted a dull rumble and proceeded to hurl bolts of electricity into the sky. The blinding flashes, The New York Sun reported, “seemed to shoot off into the darkness on some mysterious errand.”

But the system failed for want of money, and at least partly for scientific viability. Tesla never finished his prototype tower and was forced to abandon its adjoining laboratory.

Today, a fight is looming over the ghostly remains of that site, called Wardenclyffe — what Tesla authorities call the only surviving workplace of the eccentric genius who dreamed countless big dreams while pioneering wireless communication and alternating current. The disagreement began recently after the property went up for sale in Shoreham, N.Y.

A science group on Long Island wants to turn the 16-acre site into a Tesla museum and education center, and hopes to get the land donated to that end. But the owner, the Agfa Corporation, says it must sell the property to raise money in hard economic times. The company’s real estate broker says the land, listed at $1.6 million, can “be delivered fully cleared and level,” a statement that has thrown the preservationists into action.

In Mercury Images, Remarkable Features in a Crater

On its second flyby of the planet Mercury last October, NASA’s Messenger spacecraft beamed back 1,200 pictures, revealing 30 percent of the planet’s surface that had never been seen up close before. Among the images was a view of the second-largest crater on Mercury, as wide as the distance from Boston to Washington.

Called the Rembrandt basin — by convention, Mercurian craters are named after painters, authors, composers and other creative artists — the crater is surprising more for the geological features within its rim than for its size, planetary scientists said last week.

Women Sue Over Device to Stop Urine Leaks
By RONI CARYN RABIN, The New York Times, May 5, 2009

It was the promise of a quick fix that appealed to Amber Suriani.

She had just turned 40 and was very fit, but whenever she went running or practiced karate — she was working on a black belt — she leaked a bit of urine.

The diagnosis was stress urinary incontinence, and her surgeon recommended a simple procedure to plug the leak by inserting a hammock made of a strip of synthetic meshlike material, called a vaginal sling, under her urethra.

“It was supposed to be a simple ‘in one day and out the next’ kind of thing,” said Ms. Suriani, now 43, who lives in a suburb of Syracuse.

Observatory: For Tough Recyclables, a Self-Mending Plastic
By HENRY FOUNTAIN, The New York Times, April 28, 2009

Most of the plastics that are recyclable today — water bottles and grocery bags, for instance — are what are called thermoplastics. They are polymers that can be melted down and molded into something else.

But there is another category of plastics, thermoset resins, that can’t be easily recycled. These polymers — the stuff of circuit boards, electrical insulation and epoxy glue, among other things — have strong cross-links and when heated tend to decompose. Most products made from these plastics end up as waste.

But chemists at the University of Groningen in the Netherlands have devised a thermoset plastic that, rather than decomposing, heals itself when heated. Writing in the journal Macromolecules, the researchers, Youchun Zhang, Antonius A. Broekhuis and Francesco Picchioni, say the material has the potential to be recycled and reused many times.

With Aid of Drug Library, New Remedies From Old
By KATE MURPHY, The New York Times, April 28, 2009

Housed in a row of white freezers in a nondescript laboratory at the Johns Hopkins University School of Medicine in Baltimore are more than 3,000 of the estimated 10,000 drugs known to medicine. There is no sign on the door to indicate that this is perhaps the largest public drug library available to researchers interested in finding new uses for old and often forgotten drugs.

Already, researchers have used the library to discover that itraconazole, a drug used for decades to treat toenail fungus, may also inhibit the growth of some kinds of tumors and may forestall macular degeneration. Another drug, clofazimine, used more than a century ago to treat leprosy, may be effective against autoimmune disorders like multiple sclerosis and psoriasis.

“It takes 15 years and costs close to a billion dollars to develop a new drug,” said Jun O. Liu, professor of pharmacology and director of the Johns Hopkins Drug Library. “Why not start with compounds that already have proven safety and efficacy?”

Books: Snapshots From the Days of Bare-Hands Anatomy
By ABIGAIL ZUGER, M.D., The New York Times, April 28, 2009

The array of familiar objects threatened by digital technology encompasses the old (books, paintings) and the new (CDs). And then there is the human body, which counts as both.

Not the bodies we use, of course, but rather the bodies we allow medical professionals to use while training, to familiarize themselves with the terrain. Dissecting a cadaver has been part of medical education for millenniums. But the cadaver that enters the gross anatomy suite with the blessing of both the prior owner and the state is actually quite a new phenomenon.

Barely a century ago American medical schools were helping themselves to alumni of the local poorhouse for some of their teaching material and paying grave robbers for the rest. Only with a 1968 federal act did a nationwide system of voluntary donation bring uniformity to the process.

Now the same technology that lets us scan living bodies in all dimensions may obviate our need for dead ones, as some anatomy courses move from real dissection to its virtual counterpart — clean and odor-free, in crystal-clear focus with infinite zoom.

Some say virtual anatomy can never replace the transcendent reality. Some say it is a huge improvement over smelly, greasy, inconvenient flesh. Both arguments will be fueled by “Dissection,” an extraordinary collection of photographs that makes even today’s flesh-and-blood anatomy laboratories look tame.

More boys than girls are born all over the world, but a new study has found that the closer people live to the equator, the smaller the difference becomes. No one knows why.

The skewed sex ratio at birth has been known for more than a hundred years, and researchers have found a large variety of social, economic and biological factors that correlate with it — war, economic stress, age, diet, selective abortion or infanticide and more. Teasing out the contribution of any single cultural or political variable has proved an almost infinitely complicated exercise.

Ill From Food? Investigations Vary by State

In just about every major contaminated food scare, Minnesotans become sick by the dozens while few people in Kentucky and other states are counted among the ill.

Contaminated peanuts? Forty-two Minnesotans were reported sick compared with three Kentuckians. Jalapeño peppers last year? Thirty-one in Minnesota and two in Kentucky became ill. The different numbers arise because health officials in Kentucky and many other states fail to investigate many complaints of food-related sickness while those in Minnesota do so diligently, safeguarding not only Minnesotans but much of the rest of the country, as well.

18 and Under: Another Awkward Sex Talk: Respect and Violence
By PERRI KLASS, M.D., The New York Times, April 14, 2009

Not long ago, in the clinic, a fellow pediatrician and mother asked whether we were still teaching our sons old-fashioned elevator etiquette: stand back and let the ladies off first.

We all protested that we don’t particularly like it when men pull that elevator stunt — hospital elevators tend to be packed, and the best thing to do if you’re near the door is get out promptly — but we had to admit we thought our adolescent sons should know the drill.

Once you start asking about whether there are special lessons that should be taught to boys, people jump pretty quickly from elevators to sex (or maybe that’s just the crowd I run with). Sex, after all, is a subject on which pediatricians give plenty of advice. And it becomes very tricky to formulate that advice without making some unpleasant assumptions about adolescent sexuality.

Personal Health: Keeping Those Bed Bugs From Biting
By JANE E. BRODY, The New York Times, April 14, 2009

Throughout my early childhood I was tucked into bed with a gentle admonition: “Good night, sleep tight. Don’t let the bed bugs bite.” Not that my parents or I had ever seen a bed bug or known anyone bitten by one.

But these days this old saying has resonance for many more people than in years past, including those who sleep in expensive homes and four-star hotels. Last month, a family living in a $3 million private house in Brooklyn discarded rooms’ worth of furniture, the cushions carefully slashed and notes attached saying the pieces had bed bugs and were not safe to take.

Had this been the case 40-odd years ago when I became a New York homeowner, I might have had a hard time furnishing my rooms; most were decorated with foundlings, including cushioned chairs. In those days, street scavengers like me had little reason to worry about bed bugs.

But the bed bug problem has become so widespread in 21st- century America that The Journal of the American Medical Association published a clinical review in April, “Bed Bugs and Clinical Consequences of Their Bites,” by Jerome Goddard, a medical entomologist at Mississippi State University, and Dr. Richard deShazo, an allergist at the University of Mississippi Medical Center.

Mind: When All You Have Left Is Your Pride
By BENEDICT CAREY, The New York Times, April 7, 2009

Look around you. On the train platform, at the bus stop, in the car pool lane: these days someone there is probably faking it, maintaining a job routine without having a job to go to.

The Wall Street type in suspenders, with his bulging briefcase; the woman in pearls, thumbing her BlackBerry; the builder in his work boots and tool belt — they could all be headed for the same coffee shop, or bar, for the day.

“I have a new client, a laid-off lawyer, who’s commuting in every day — to his Starbucks,” said Robert C. Chope, a professor of counseling at San Francisco State University and president of the employment division of the American Counseling Association. “He gets dressed up, meets with colleagues, networks; he calls it his Western White House. I have encouraged him to keep his routine.”

Answering Baseball’s What-Ifs

You can learn a lot during a major league baseball game. Like Ukrainian, if it is a particularly slow nine innings.

As for the science of baseball strategy, one game teaches precious little. A well-timed sacrifice bunt can backfire and lose the game; a foolish steal can appear brilliant. The vagaries of randomness — the way Sandy Koufax got battered occasionally and a pipsqueak named Bucky Dent hit one of the most famous home runs ever — camouflage the game’s inner forces, which for 150 years have operated somewhere between fact and fable.

Scratching Relieves Itch by Quieting Nerve Cells
By BENEDICT CAREY, The New York Times, April 7, 2009

As common as it is, scratching to relieve an itch has long been considered a biological mystery: Are cells at the surface of the skin somehow fatigued, in need of outside stimulation? Or is the impulse, and its relief, centered in the brain?

Perhaps neither one, a new study suggests. Neuroscientists at the University of Minnesota report that specialized cells in the spinal cord appear to be critically involved in producing the sensation of itch and the feeling of relief after the application of fingernails, at least in healthy individuals. The study appears in the current issue of the journal Nature Neuroscience.

House Dust Yields Clue to Asthma: Roaches
By ELISSA ELY, M.D, The New York Times, April 7, 2009

Asthma is the most common chronic disease of childhood, one that strikes the poor disproportionately. Up to one-third of children living in inner-city public housing have allergic asthma, in which a specific allergen sets off a cascade of events that cause characteristic inflammation, airway constriction and wheezing.

Now, using an experimental model that required leaving the pristine conditions of the lab for the messier ones of life, a team of scientists from the Boston University School of Medicine have discovered what that allergen is.

“For inner-city children,” said the lead researcher, Dr. Daniel G. Remick, a professor of pathology, “the major cause of asthma is not dust mites, not dog dander, not outdoor air pollen. It’s allergies to cockroaches.”

Observatory: Near-Complete Fossil Offers Insight on Early Fish
By HENRY FOUNTAIN, The New York Times, March 31, 2009

In trying to make evolutionary sense of the bony fish (and, by extension, land vertebrates) scientists have been hampered by a lack of completeness. Most of the earliest fossils of bony fish, dating to the Silurian period more than 416 million years ago, are fragmentary — a jawbone here, a tooth there.

A new find from limestone deposits in southern China is helping to clarify the situation. In a paper in Nature, Min Zhu and colleagues at the Institute of Vertebrate Paleontology and Paleoanthropology of the Chinese Academy of Sciences describe a well-preserved and practically complete fish fossil that is 418 million years old.

There on Interstate 35W, the St. Anthony Falls Bridge carries 10 lanes of traffic on box girders borne by massive arching piers, which are supported, in turn, by footings and deep pilings.

The bridge, built to replace one that collapsed in 2007, killing 13 people, is constructed almost entirely of concrete embedded with steel reinforcing bars, or rebar. But it is hardly a monolithic structure: the components are made from different concrete mixes, the recipes tweaked, as a chef would, for specific strength and durability requirements and to reduce the impact on the environment. One mix, incorporated in wavy sculptures at both ends of the bridge, is designed to stay gleaming white by scrubbing stain-causing pollutants from the air.

Visual Science: Fine-Grained Genetic Data
By NICHOLAS WADE, The New York Times, March 31, 2009

The English and Irish are raised in the knowledge that they are very different from one another, so are bemused to find that in the United States often no such difference is recognized. Which perspective is correct?

A team of Australian geneticists interested in assessing the sources of emigration to Australia has now provided a judicious answer. From the genetic perspective, as is shown in the graphic above, the two populations are very similar, yet with the help of powerful gene chips they can be distinguished from one another, as well as from other northern European populations such as the Dutch, Danes, Swedes and Finns.

Oozing Through Texas Soil, a Team of Amoebas Billions Strong
By CAROL KAESUK YOON, The New York Times, March 24, 2009

After producing superlatives like the world’s biggest statue of a jackrabbit and the nation’s most unpopular modern-day president, Texas can now boast what may be its most bizarre and undoubtedly its slimiest topper yet: the world’s largest known colony of clonal amoebas.

Scientists found the vast and sticky empire stretching 40 feet across, consisting of billions of genetically identical single-celled individuals, oozing along in the muck of a cow pasture outside Houston.

“It was very unexpected,” said Owen M. Gilbert, a graduate student at Rice University and lead author of the report in the March issue of Molecular Ecology. “It was like nothing we’d ever seen before.”

Scientists say the discovery is much more than a mere curiosity, because the colony consists of what are known as social amoebas. Only an apparent oxymoron, social amoebas are able to gather in organized groups and behave cooperatively, some even committing suicide to help fellow amoebas reproduce. The discovery of such a huge colony of genetically identical amoebas provides insight into how such cooperation and sociality might have evolved and may help to explain why microbes are being found to show social behaviors more often than was expected.

The Doctor's World: A Quandary in Sweden: Criminals in Med School
By LAWRENCE K. ALTMAN, M.D., The New York Times, March 24, 2009

A year ago, Sweden’s most prestigious medical school found itself in an international uproar after it unknowingly admitted a student who was a Nazi sympathizer and a convicted murderer, then scrambled to find a way to expel him.

It is hard to imagine how the case could get any more bizarre. But it has.

The 33-year-old student, Karl Helge Hampus Svensson, having been banished from the medical school of the Karolinska Institute in Stockholm on the ground that he falsified his high school records, has now been admitted to a second well-known medical school — Uppsala, Sweden’s oldest university.

New twists in his and another case highlight the difficulties that three of the country’s six medical schools have had in admitting and dismissing students with serious criminal offenses in just the past two years. The cases resonate far beyond Sweden, raising fundamental questions about who is fit to become a doctor.

Findings: Oversaving, a Burden for Our Times
By JOHN TIERNEY, The New York Times, March 24, 2009

We interrupt this recession to bring you news of another crisis that is much more pleasant to deal with. Now that shoppers have sworn off credit cards, we’re risking an epidemic of a hitherto neglected affliction: saver’s remorse.

The victims won’t evoke much sympathy — don’t expect any telethons — but their condition is real enough to merit a new label. Consumer psychologists call it hyperopia, the medical term for farsightedness and the opposite of myopia, nearsightedness, because it’s the result of people looking too far ahead. They’re so obsessed with preparing for the future that they can’t enjoy the present, and they end up looking back sadly on all their lost opportunities for fun.

An Outbreak of Autism, or a Statistical Fluke?
By DONALD G. McNEIL Jr., The New York Times, March 17, 2009

MINNEAPOLIS — Ayub Abdi is a cute 5-year-old with a smile that might be called shy if not for the empty look in his eyes. He does not speak. When he was 2, he could say “Dad,” “Mom,” “give me” and “need water,” but he has lost all that.

He does scream and spit, and he moans a loud “Unnnnh! Unnnnh!” when he is unhappy. At night he pounds the walls for hours, which led to his family’s eviction from their last apartment.

As he is strapped into his seat in the bus that takes him to special education class, it is hard not to notice that there is only one other child inside, and he too is a son of Somali immigrants.

“I know 10 guys whose kids have autism,” said Ayub’s father, Abdirisak Jama, a 39-year-old security guard. “They are all looking for help.”

Autism is terrifying the community of Somali immigrants in Minneapolis, and some pediatricians and educators have joined parents in raising the alarm. But public health experts say it is hard to tell whether the apparent surge of cases is an actual outbreak, with a cause that can be addressed, or just a statistical fluke.

The Fall and Rise of the Right Whale
By CORNELIA DEAN, The New York Times, March 17, 2009

ST. SIMONS ISLAND, Ga. — The biologists had been in the plane for hours, flying back and forth over the calm ocean. They had seen dolphins, leatherback turtles, a flock of water birds called gannets and even a basking shark — but not what they were looking for.

Then Millie Brower, who was peering with intense concentration through a bubblelike window fitted into the plane’s fuselage, announced “nine o’clock, about a mile off.” The plane made a stomach-churning lurch as the pilots banked left and began to circle. And there, below, were a right whale mother and her new calf, barely breaking the surface, lolling in the swells.

The researchers, from the National Oceanic and Atmospheric Administration and the Georgia Wildlife Trust, are part of an intense effort to monitor North Atlantic right whales, one of the most endangered, and closely watched, species on earth. As a database check eventually disclosed, the whale was Diablo, who was born in these waters eight years ago. Her calf — at a guess 2 weeks old and a bouncing 12 feet and 2 tons — was the 38th born this year, a record that would be surpassed just weeks later, with a report from NOAA on the birth of a 39th calf. The previous record was 31, set in 2001.

From Arctic Soil, Fossils of a Goliath That Ruled the Jurassic Seas
By JOHN NOBLE WILFORD, The New York Times, March 17, 2009

There were monstrous reptiles in the deep, back in the time of dinosaurs.

They swam with mighty flippers, two fore and two hind, all four accelerating on attack. In their elongated heads were bone-crushing jaws more powerful than a Tyrannosaurus rex’s. They were the pliosaurs, heavyweight predators at the top of the food chain in ancient seas.

Much of this was already known. Now, after an analysis of fossils uncovered on a Norwegian island 800 miles from the North Pole, scientists have confirmed that they have found two partial skeletons of a gigantic new species, possibly a new family, of pliosaurs.

This extinct marine reptile was at least 50 feet long and weighed 45 tons, the largest known of its kind. Its massive skull was 10 feet long, and the flippers, more like outsize paddles, were also 10 feet. The creature — not yet given a scientific name but simply called the Monster or Predator X — hunted the seas 150 million years ago, in the Jurassic Period.

News Analysis: Rethink Stem Cells? Science Already Has
By NICHOLAS WADE, The New York Times, March 10, 2009

With soaring oratory, President Obama on Monday removed a substantial practical nuisance that has long made life difficult for stem cell researchers. He freed biomedical researchers using federal money (a vast majority) to work on more than the small number of human embryonic stem cell lines that were established before Aug. 9, 2001.

In practical terms, federally financed researchers will now find it easier to do a particular category of stem cell experiments that, though still important, has been somewhat eclipsed by new advances.

Findings: What Do Dreams Mean? Whatever Your Bias Says
By JOHN TIERNEY, The New York Times, March 10, 2009

Suppose last night you had two dreams. In one, God appears and commands you to take a year off and travel the world. In the other, God commands you to take a year off to go work in a leper colony.

Which of those dreams, if either, would you consider meaningful?

Or suppose you had one dream in which your friend defends you against enemies, and another dream in which that same friend goes behind your back and tries to seduce your significant other? Which dream would you take seriously?

Tough questions, but social scientists now have answers — and really, it’s about time. For thousands of years, dreamers have had little more to go on than the two-gate hypothesis proposed in “The Odyssey.” After Penelope dreams of the return of her lost-long husband, she’s skeptical and says that only some dreams matter.

Rewards for Students Under a Microscope
By LISA GUERNSEY, The New York Times, March 3, 2009

For decades, psychologists have warned against giving children prizes or money for their performance in school. “Extrinsic” rewards, they say — a stuffed animal for a 4-year-old who learns her alphabet, cash for a good report card in middle or high school — can undermine the joy of learning for its own sake and can even lead to cheating.

But many economists and businesspeople disagree, and their views often prevail in the educational marketplace. Reward programs that pay students are under way in many cities. In some places, students can bring home hundreds of dollars for, say, taking an Advanced Placement course and scoring well on the exam.

Whether such efforts work or backfire “continues to be a raging debate,” said Barbara A. Marinak, an assistant professor of education at Penn State, who opposes using prizes as incentives. Among parents, the issue often stirs intense discussion. And in public education, a new focus on school reform has led researchers on both sides of the debate to intensify efforts to gather data that may provide insights on when and if rewards work.

For the best protection against winter flu, adults may just have to roll up their sleeves and take shots the old-fashioned way.

After reviewing the medical records of more than one million members of the United States military over a three-year period, researchers have found that conventional intramuscular shots reduced doctor visits for flulike symptoms by up to 54 percent, while an intranasal vaccine curbed flu-related visits by just 21 percent at best.

Q & A: The Arctic Larder

Q. We are always told a balanced diet with plenty of nutritious fresh produce is needed for good health. How did people avoid malnutrition in societies, like those in the Arctic, where historically there was little or no produce?

A. It is a misperception that traditional Eskimo and other Arctic diets included no fresh plant food, though it was limited. In fact, early explorers found that malnutrition and deficiency problems like scurvy could be avoided by adopting a “primitive” diet of fresh fish and meat, with occasional ground plants and berries.

Essay: The Evolutionary Search for Our Perfect Past
By MARLENE ZUK, The New York Times, January 20, 2009

Remember when life was simpler, and diets weren’t full of processed food and chemicals? No, not the 1950s. Increasingly, we are developing nostalgia for a much earlier epoch: the Pleistocene, when humans lived in small hunter-gatherer groups and didn’t worry about high cholesterol.

Although the box-office lure of skimpy fur garments cannot be underestimated, movies like “10,000 B.C.” are popular because they appeal to our sense that life used to be more in sync with the environment. A recent cartoon shows one of those evolutionary progressions — ape to man walking upright to man slouched over a computer — with the caption “Somewhere, something has gone terribly wrong.”

Maybe our woes arise because our Stone Age genes are thrust into Space Age life. That beer gut? It comes from eating too many processed carbohydrates; our bodies evolved to eat only unrefined foods, mainly meat, and we get out of kilter veering from our ancestral diet.

Food allergies and digestive woes? We, like other mammals, aren’t meant to consume dairy products after weaning. When politicians fall from grace after committing adultery, some commentator will always point out that such behavior has evolutionary roots: weren’t the best procreators alpha males with roving eyes?

In short, we have what the anthropologist Leslie Aiello called “paleofantasies.” She was referring to stories about human evolution based on limited fossil evidence, but the term applies just as well to nostalgia for the very old days as a touchstone for the way life is supposed to be and why it sometimes feels so out of balance.

As an evolutionary biologist, I was filled with enthusiasm at first over the idea of a modern mismatch between everyday life and our evolutionary past. But a closer look reveals that not all evolutionary ideas are created equal; even for Darwinians, the devil is in the details. The notion that there was a time of perfect adaptation, from which we’ve now deviated, is a caricature of the way evolution works.

Personal Best: Fitness Isn’t an Overnight Sensation
By GINA KOLATA, The New York Times, January 22, 2009

CARL FOSTER, an exercise physiologist at the University of Wisconsin, La Crosse, was amused by ads for a popular piece of exercise equipment. Before-and-after photos showed pudgy men and women turned into athletes with ripped bodies of steel. And it all happened after just 12 weeks of exercising for 30 minutes three times a week. Then there was the popular book, with its own before-and-after photos, promoting a program that would totally change your body in six weeks with three 20-minute exercise sessions a week.

There are many examples of people who took up exercise and markedly changed their appearance. But how long does it take? And how much time and effort are required? Six weeks sounded crazy to Dr. Foster.

A Bicycle Evangelist With the Wind Now at His Back

PORTLAND, Ore. — For years, Earl Blumenauer has been on a mission, and now his work is paying off. He can tell by the way some things are deteriorating around here.

“People are flying through stop signs on bikes,” Mr. Blumenauer said. “We are seeing in Portland bike congestion. You’ll see people biking across the river on a pedestrian bridge. They are just chock-a-block.”

Mr. Blumenauer, a passionate advocate of cycling as a remedy for everything from climate change to obesity, represents most of Portland in Congress, where he is the founder and proprietor of the 180 (plus or minus)-member Congressional Bicycle Caucus. Long regarded in some quarters as quixotic, the caucus has come into its own as hard times, climate concerns, gyrating gas prices and worries about fitness turn people away from their cars and toward their bikes.

A Breakthrough in Imaging: Seeing a Virus in Three Dimensions
By JOHN MARKOFF, The New York Times, January 13, 2009

For the first time, researchers at an I.B.M. laboratory have captured a three-dimensional image of a virus.

The technique used by the I.B.M. scientists has some similarity to magnetic resonance imaging, or M.R.I., now routinely used by physicians to peer inside the human body. But the results were 100 million times better in terms of resolution with the new technique, magnetic resonance force microscopy, or M.R.F.M. The team of researchers, based at the computer maker’s Almaden Research Center in San Jose, Calif., reports in the The Proceedings of the National Academy of Sciences that they have captured a 3-D image of a tobacco mosaic virus with a spatial resolution down to four nanometers.

For Privacy’s Sake, Taking Risks to End Pregnancy
By JENNIFER 8. LEE and CARA BUCKLEY, The New York Times, January 5, 2009

Amalia Dominguez was 18 and desperate and knew exactly what to ask for at the small, family-run pharmacy in the heart of Washington Heights, the thriving Dominican enclave in northern Manhattan. “I need to bring down my period,” she recalled saying in Spanish, using a euphemism that the pharmacist understood instantly.

It was 12 years ago, but the memory remains vivid: She was handed a packet of pills. They were small and white, $30 for 12. Ms. Dominguez, two or three months pregnant, went to a friend’s apartment and swallowed the pills one by one, washing them down with malta, a molasseslike extract sold in nearly every bodega in the neighborhood.

The cramps began several hours later, doubling Ms. Dominguez over, building and building until, eight and a half hours later, she locked herself in the bathroom and passed a lifeless fetus, which she flushed.

The pills were misoprostol, a prescription drug that is approved by the Food and Drug Administration for reducing gastric ulcers and that researchers say is commonly, though illegally, used within the Dominican community to induce abortion. Two new studies by reproductive-health providers suggest that improper use of such drugs is one of myriad methods, including questionable homemade potions, frequently employed in attempts to end pregnancies by women from fervently anti-abortion cultures despite the widespread availability of safe, legal and inexpensive abortions in clinics and hospitals.

Well: With the Right Motivation, That Home Gym Makes Sense
By TARA PARKER-POPE, The New York Times, January 6, 2009

A year ago, I bought an elliptical trainer — a gym-quality machine that I felt certain would get a daily workout.

Today, my top-of-the-line exercise machine sits idle most of the time. But I’m not alone. Every year, consumers spend an estimated $4 billion on home treadmills, stationary bikes, Stairmasters and other equipment that ends up gathering dust. A Consumer Reports survey last year found that nearly 40 percent of those who buy home exercise machines say they use them less than they expected.

This may be discouraging to people like me, but it is a source of fascination for behavioral scientists. The hope is that by better understanding the behavior, they can help people make better buying decisions — and help them start exercising and stick with it.

Observatory: Bigger Sea Creatures, Like Squid, May Feel Effects of Higher CO2
By HENRY FOUNTAIN, The New York Times, December 23, 2008

Increased emissions of carbon dioxide affect more than the atmosphere. Much of the CO2 is absorbed by the oceans, causing them to become more acidic.

Recent research has looked at the impact of the acidification on corals and other small calcifying organisms. But increasing CO2, coupled with gradual warming of the oceans, may have other effects, and may affect bigger creatures, because there will be less oxygen at the surface and deep oxygen-poor zones will expand vertically.

A study in The Proceedings of the National Academy of Sciences looks at the potential effects on one of those bigger creatures, the Humboldt squid, which can be six feet long and weigh more than 100 pounds. Rui Rosa and Brad A. Seibel of the University of Rhode Island put squid in a flow-through respirometer that allowed measurements of metabolism while concentrations of gases in the water were changed.

Basics: A Highly Evolved Propensity for Deceit

When considering the behavior of putative scam operators like Bernard “Ponzi scheme” Madoff or Rod “Potty Mouth” Blagojevich, feel free to express a sense of outrage, indignation, disgust, despair, amusement, schadenfreude. But surprise? Don’t make me laugh.

Sure, Mr. Madoff may have bilked his clients of $50 billion, and Governor Blagojevich, of Illinois, stands accused of seeking personal gain through the illicit sale of public property — a United States Senate seat. Yet while the scale of their maneuvers may have been exceptional, their apparent willingness to lie, cheat, bluff and deceive most emphatically was not.

Deceitful behavior has a long and storied history in the evolution of social life, and the more sophisticated the animal, it seems, the more commonplace the con games, the more cunning their contours.

Cases: From a Place of Fire and Weeping, Lessons on Memory, Aging and Hope
By MARC E. AGRONIN, M.D., The New York Times, December 23, 2008

Place of fire,

place of weeping,

place of madness

— Zelda, “Place of Fire”


The forest still stands, but the people are gone. Only a stone memorial guards their place, surrounded by tall grasses that hide bits of ash and bone deep beneath their roots.

On this spot on Feb. 4, 1942, more than 920 Jewish men, women and children from the town of Rakov in what is now Belarus were rounded up by the Nazis and herded into the synagogue. Several shrieking children were stabbed with bayonets and thrown over the heads of the weeping Jews just before the doors and windows were sealed and the building was doused with kerosene.

An unspeakable scene of wailing ensued as the once vibrant Jewish community was annihilated in the fire. My patient, now 98, still weeps when he describes witnessing this horror from a hidden perch in a tree. He gasps audibly when he recalls watching his father being pummeled by a Nazi soldier before he was thrust into the doomed crowd.

When this survivor first told me his story, I was speechless. He held tight to my arm, and I imagined myself as the branches of the tree that supported him during this trauma. I was now a witness.

As his psychiatrist I am obliged to ease his suffering, but no medicine of mine can touch such a memory. I have tried hard to understand how he and others managed to mentally survive such traumatic experiences. These aging Holocaust survivors, in particular, have taught me what I have come to call “lessons from fire.”

D. Carleton Gajdusek, Who Won Nobel for Work on Brain Disease, Is Dead at 85

D. Carleton Gajdusek, a virologist who won the 1976 Nobel Prize in medicine for his work on the mysterious epidemics now known as prion diseases, died last week in Tromso, Norway.

The cause of death is unknown, but Dr. Gajdusek (pronounced GUY-dah-shek) was 85 and had long had congestive heart failure, said Dr. Robert Klitzman, his biographer, who said he had spoken to him about a week ago. He was found in his Tromso hotel room on Friday morning about 24 hours after a manager saw him at breakfast.

In later life, Dr. Gajdusek became notorious when he was charged with molesting the many young boys he had adopted in New Guinea and Micronesia and brought to live with him in Maryland. He pleaded guilty to one charge, served a year in prison and left the United States in 1998, dividing his time between Paris, Amsterdam and Tromso.

Get Along Without a Pinkie? It’s Tougher Than You Might Think

Researchers Put a Microscope on Food Allergies
By KAREN ANN CULLOTTA, The New York Times, December 9, 2008

CHICAGO — For 5-year-old Sean Batson, even a grandmother’s kiss is to be feared.

“My mother was wearing lipstick, and when she kissed Sean’s cheek, it broke out in hives,” said his mother, Jennifer Batson.

At his first birthday party, Sean had a severe allergic reaction — hives, swollen eyes, vomiting and wheezing — to his first nibble of cake. And when a toddler with an ice cream cone touched Sean’s arm with sticky hands during a play date, the arm erupted in hives.

The daily struggle of living with Sean’s allergies to nearly unavoidable foods and food products — soy, eggs and milk, traces of which can turn up even in nonfoods like lipstick — prompted Mrs. Batson and her husband, Tim, to participate in a project that scientists are calling the most comprehensive food allergy study to date.

Scorpios Get More Asthma, but Astrology Isn’t to Blame
By TARA PARKER-POPE, The New York Times, December 9, 2008

How, when and where a child is born may all play a role in lifetime asthma risk, new studies suggest.

Asthma occurs when airways in the lungs spasm and swell, restricting the supply of oxygen. The incidence of asthma in the United States has risen steadily for more than two decades, and about 6 percent of children now have asthma, up from less than 4 percent in 1980, according to the Centers for Disease Control and Prevention.

The reasons for the increase are not entirely clear. Genetics probably plays a role in the risk for asthma, but an array of environmental factors — pollen, dust, animal dander, mold, cockroach feces, cigarettes, air pollution, viruses and cold air — have all been implicated in its development.

This month, The American Journal of Respiratory and Critical Care Medicine is reporting that children born in the fall have a 30 percent higher risk for asthma than those born in other seasons. The finding is based on a review of birth and medical records of over 95,000 children in Tennessee.

By PERRI KLASS, M.D, The New York Times, December 9, 2008

Some years ago, in the candor of the exam room, a seventh-grade boy told me that he didn’t really have friends at school, and that he sometimes found himself being picked on. I gave him the pediatric line on bullying: it shouldn’t be tolerated, and there are things schools can do about it. Let’s talk to your parents, let’s have your parents talk to the school; adult interventions can change the equation.

And he was horrified. He shook his head vehemently and asked me please not to interfere, and above all not to say a word to his mother, who was out in the waiting room because I had asked her to give us some privacy.

He wouldn’t have told me this at all, he said, except he thought our conversation was private. The situation at school wasn’t all that bad; he could handle it. He wasn’t in any danger, wasn’t getting hurt, he was just a little lonely. His parents, he said, thought that he was fine, that he had lots of friends, and he wanted to keep it that way.

Winners of Prestigious Student Science Awards Are Named
By AMANDA M. FAIRBANKS, The New York Times, December 9, 2008

Practical advances in medicine ruled the day in the Siemens Competition in Math, Science and Technology, one of the nation’s most coveted student science awards, whose winners were announced Monday morning at New York University.

While highly regarded, a Tamari lattice, a mathematical structure, and Bax and Bak, two proteins, lost out to a project by Wen Chyan, 17, a senior at the Texas Academy of Mathematics and Science in Denton, Tex. Mr. Wen won the top individual prize — a $100,000 scholarship — for research on fighting hospital-related infections with antimicrobial coatings for medical devices.

For genetics research that has the potential to identify new chemotherapeutic drugs and improve existing ones, Sajith M. Wickramasekara and Andrew Y. Guo, both 17 and seniors at the North Carolina School of Science and Mathematics in Durham, N.C., took home $50,000 each — the top team prize.
