The 1997-98 El Niño had an unprecedented effect on the oceanic food chain across a vast swath of the Pacific.

El Niño's dramatic impact on ocean biology, carbon dioxide captured by unique monitoring system
The 1997-98 El Niño/La Niña had an unprecedented roller- coaster effect on the oceanic food chain across a vast swath of the Pacific, plunging chlorophyll levels to the lowest ever recorded in December 1997 and spawning the largest bloom of microscopic algae ever seen in the region the following summer.

Bacteria may thrive in Antarctic lake
Two separate investigations of ice drilled at Lake Vostok, a suspected body of subglacial water deep in the Antarctic interior, indicate that bacteria may live thousands of meters below the ice sheet.

Traffic congestion 'temperature' could forecast delays
A Georgia Tech researcher is developing a cutting-edge traffic flow model that analyzes a variety of historical data and a host of variables to predict the next day's traffic conditions.

Evidence of bacterial life found in deepest-yet Antarctic ice-core
Analysis of an Antarctic ice core suggests that bacteria may live in a fresh-water subglacial lake - an extreme environment that may be Earth's closest analog to a frozen moon of Jupiter.

Protein found that turns brain enzyme into possible trigger for Alzheimer's tangles
Breaking an impasse in Alzheimer's research, Harvard Medical School scientists have identified in the brains of patients a protein, called p25, that can initiate the subtle molecular changes known to lead to neurofibrillary tangles, one of the disease's pathological hallmarks.

Team led by MSU biologist finds bacteria deep in Antarctic ice
A team led by Montana State University-Bozeman biologist John Priscu has discovered bacteria in an ice core drilled from deep within a frozen Antarctic lake.

Scientists map brain's primary memory network
For the first time, a team of Wake Forest University investigators has mapped the functional organization of the hippocampus, the brain's primary memory network, a step that other scientists are calling

Nurse shortage looms in California and nationwide
California faces a shortage of registered nurses and needs to increase the supply to keep pace with the rapid growth of the state's population, according to a study by researchers at the University of California, San Francisco and the Public Policy Institute of California.

Cedars-Sinai Medical tip sheet for Dec. 9
1. Cedars-Sinai skull base surgeon performs world's first fully endoscopic microvascular decompression; 2.

Zebrafish's powerful heart gene could lead to transplant therapy
Researchers have discovered a gene in zebrafish so powerful it can be used to redirect the fate of cells in the developing embryo to become beating heart cells, suggesting that a similar gene in humans could be used to generate heart cells in culture for transplant in ailing people.

It's not just Einstein: Study shows differences in male brain
Scientists at Johns Hopkins have discovered

3-D structure of human transcription factor proteins revealed
The first three-dimensional images of the protein complex that initiates the transcription of DNA's genetic code for the subsequent production of new proteins have been produced by scientists with the Lawrence Berkeley National Laboratory (Berkeley Lab) and the University of California at Berkeley.

Vion's TAPET® administered to first patients in Phase I human intratumoral safety trial at the Cleveland Clinic Foundation
Vion announced that VNP20009, the company's TAPET® bacterial vector, has been administered to patients enrolled in its Phase I trial at The Cleveland Clinic Foundation.

UNC-CH scientist finds smallest number of genes needed for organism's survival
The minimum number of protein-producing genes a single-celled organism needs to survive and reproduce in the laboratory is somewhere between 265 and 350, according to new research directed by a top University of North Carolina at Chapel Hill scientist.

Targeted Genetics presents advances in synthetic gene delivery technologies
Targeted Genetics Corporation (Nasdaq: TGEN) presents data on the Company's synthetic gene delivery technology platform at the Eighth International Conference on Gene Therapy of Cancer being held in San Diego.

Abgenix and CuraGen establish large-scale drug development alliance, companies to develop genomics-based human antibody drugs
Abgenix, Inc., an antibody-based biopharmaceutical company, and CuraGen Corporation, an integrated genomics-based drug discovery and development company, have formed a five-year strategic alliance to develop and commercialize genomics- based fully human antibody drugs using XenoMouse™ technology.

Montreal researchers announce new vaccine approach to stimulate regeneration after spinal cord injuries
A new vaccine approach to block molecules in the spinal cord that prevent nerve regeneration was successfully tested by Dr.David Samuel of the Montreal General Hospital Research Institute/McGill University Hospital Centre, the lead investigator on the project, Dr.

Researchers discover early trigger of Alzheimer's disease
HHMI researchers studying the brain cells of patients with Alzheimer's disease have identified a molecule that triggers the early formation of some of the deadly snarls of protein that damage and kill brain cells.

New UCSF study shows gay men smoke more than general male population
Cigarette smoking is significantly more prevalent among gay men than in the general adult male population, underscoring a need for anti-smoking campaigns that target gays, say researchers at the University of California, San Francisco.
