"I would just pick up the answer even before he finished the calculations," she says.Despite her pedigree predilection, Va

An ancient scourge, tuberculosis has made a comeback in recent years.

Just before the holidays, Kenneth Casey's young grand-daughter accidentally slammed the tip of her finger in a car door.

New methods of generating pluripotent cells may placate critics, but may not work, say scientists

Scientists at Purdue University, led by Graham Cooks, professor of analytical chemistry, recently reported a novel method for processing samples for mass spectrometry (MS) analysis.

Joelle BoltAfter garnering data on the harmful effects of dust from sewage sludge used as fertilizer on US and Canadian farms, David Lewis, former microbiologist with the Environmental Protection Agency (EPA), spoke out in Nature articles.12 The ensuing confrontation with his superiors would get him terminated from the EPA. "I never thought of myself as a whistleblower," he says. To Lewis, whistleblowers pointed fingers at people who fraudulently spent government money to buy things like private

Agriculture interest groups support idea, provided that it's funded with 'new' money

Open reading frames (ORFs) are represented as pointed boxes showing the direction of transcription, with colors reflecting the functional classification of the ORFs similar to the ones on the TubercuList server http://genolist.pasteur.fr/TubercuList/.Not long after the genome sequence of Mycobacterium tuberculosis was

A SINGLE-SPIN MRFM EXPERIMENT© 2004 Nature Publishing Groupcan probe spins as deep as 100 nm below the sample surface. The magnetic tip at the end of an ultrasensitive silicon cantilever is positioned 125 nm above a polished SiO2 sample containing a low density of unpaired electron spins. The resonant slice represents those points in the sample where the field from the magnetic tip (plus an external field) matches the condition for magnetic resonance.

Still, despite press coverage of vocal opponents, there are Bush supporters among scientists

MUTAGENS AND MITOSIS:Courtesy of Thea GoepfertSection cut through the mammary gland of a rat that had been treated with the carcinogen MNU. Centrosomes (green) are arranged at the base of each nucleus (red), and 45% of cells show amplified chromosomes.Comments from journal article reviewers often surprise or frusrate. But the reviewer response that cell biologist William Brinkley received six years ago left him stunned.Brinkley and his collaborator, Subrata Sen at the University of Texas M.D. An

Two recent reports offer a taste to the little-known underlying immunological mechanisms of celiac disease, a digestive autoimmune disorder triggered by gluten protein, which affects as many as 1 in 100 people in the United States.Working ex vivo, a University of Chicago group found that interleukin-15 overexpression helps convert antigen-specific cytotoxic T lymphocytes (CTLs) into rogue lymphokine-activated killers (LAKs) via the CTL receptor NKG2D.1 The LAK cells provoke a more general immune

"I'm all out of ideas," says hydrologist Mike Gooseff, still smiling despite his frustration.On a crisp, unusually warm and dry August afternoon on Alaska's North Slope, a few miles from the Toolik Lake Long-Term Ecological Research (LTER) field station, a two-meter metal rod is wedged in pristine streambed, irretrievable despite nearly an hour of yanking, pushing, prodding, and countless Rube-Goldberg-like brainstorms. Someone had forgotten to slip on a metal piece that would give a jack enough

TAMARISK ASSESSMENT:Courtesy of James ClossFour sites in Colorado and Utah where joint USGS-NASA teams are conducting studies of the invasive species, tamarisk.While aerospace engineers at NASA's Goddard Laboratories, northeast of Washington, DC, look down from the heavens, ecologists at a neighboring United States Geological Survey (USGS) have a closer view. Scientists from these disparate fields, ecology and aerospace, have begun collaborating in hopes of stemming a huge and ever-growing invas
