SCIENTIST AT WORK | ERIN PETTIT: Young Women Get Serious in a Laboratory of Ice
By MARGARET WERTHEIM, The New York Times, March 8, 2005

TAYLOR VALLEY, Antarctica - At Blood Falls on the Taylor Glacier, iron oxides streak down the face of a pristine ice cliff as if the glacier were bleeding from a wound. No one knows why the oxides, which are believed to leach up from a subglacial lake, appear at just this spot, but the effect is stunning, a febrile flash of color in a landscape of ice and stone.

This is one of the few places on the Antarctic continent that is not covered in ice. Bare rock and dirt rule here. Utterly devoid of vegetation, this may as well be another planet.

Indeed, researchers for the National Aeronautics and Space Administration think the region offers clues to what Mars once looked like.

SIDE EFFECTS: A World Without Males? Not Just Science Fiction for Insects
By JAMES GORMAN, The New York Times, March 8, 2005

What people dream, insects do. Ask Michael Majerus.

Dr. Majerus, a geneticist at the University of Cambridge, studies insects and the male-killing bacteria that live in them.

In his recent book, "Sex Wars: Genes, Bacteria and Biased Sex Ratios," he points out right at the start that the idea of a plague killing all the men is a common science fiction plot, while in insects, the bacteria are already at work.

Scientists unearth early skeleton: US and Ethiopian scientists say they have discovered the fossilised remains of one of the earliest human ancestors
BBC NEWS

The research team, working in the north-east of Ethiopia, believe the remains of the hominid, or primitive human, date back four million years.

They say initial study of the bones indicates the creature was bipedal - it walked around on two legs.

The fossils were found just 60km (40 miles) from the site where the famous hominid Lucy was discovered.

Lucy ( Australopithecus afarensis ), whose remains were unearthed in 1974, lived 3.2 million years ago and is thought to have given rise to the Homo line that ended in modern humans.

Hobbit was 'not a diseased human'
By Paul Rincon, BBC News science reporter

The famous skeleton from Indonesia nicknamed the "Hobbit" does not belong to a modern human pygmy with a brain disease, as some scientists argue.

That is one of the main outcomes of a detailed examination of the creature's braincase, published in Science.

The authors say their study of the Hobbit's brain supports the idea it is a new, dwarf species of human.
