Impact of biotechnology will be examined Oct. 11 at Cornell symposium

From hepatitis prevention to virtual lab animals on a chip, five scientific advances with the potential to change society will be examined at a symposium on Monday, Oct. 11, from 8:30 a.m. to 5 p.m. at Cornell.

Counting mole-rat mammaries and hungry pups, biologists explain why naked rodents break the rules

Only hungry babies and grown-up biologists worry whether there are enough mammary glands to go around. Naked mole-rat mothers don't worry. Even when a female produces more than two dozen pups.

Boyce Thompson-developed oral plant vaccine receiving first human trials for hepatitis B at Roswell Park

The Boyce Thompson Institute for Plant Research Inc., an affiliate of Cornell University, announced that clinical trials will begin today (July 7) at Roswell Park Cancer Institute in Buffalo, N.Y., to test the safety and immunogenicity of the world's first potential oral vaccine against the hepatitis B virus.

'Occupational markers' provide clues to a life, new book reveals

Dog-walker's elbow, cowboy thumb, snowmobiler's back and miner's knee are among the nearly 150 conditions described in a new book, "Atlas of Occupational Markers on Human Remains," by Luigi Capasso, Kenneth A.R. Kennedy and Cynthia A. Wilczak.

Toxic pollen from widely planted, genetically modified corn can kill monarch butterflies, Cornell study shows

An increasingly popular commercial corn, genetically engineered to produce a bacterial toxin to protect against corn pests, has an unwanted side effect: Its pollen kills monarch butterfly larvae in laboratory tests, according to a report by Cornell University researchers.

Alien animals, plants and microbes cost U.S. $123 billion a year, Cornell ecologists report

A few bad actors among the more than 30,000 non-indigenous species in the United States cost $123 billion a year in economic losses, Cornell University ecologists estimate. "It doesn't take many trouble-makers to cause tremendous damage," Cornell ecologist David Pimentel.

Simple change in cattle diets could cut E. coli infection

A simple change in cattle diets in the days before slaughter may reduce the risk of Escherichia coli (E. coli) infections in humans, U.S. Department of Agriculture (USDA) and Cornell University microbiologists have discovered.

Studies: Fetal lead exposure may increase risk of asthma, allergies, cancer

Lead in the drinking water of pregnant rats causes long-term damage to the immune systems of their offspring, according to studies at the Cornell Institute for Comparative and Environmental Toxicology.

The cocktail party effect: Fish and human brains perform 'auditory scene analysis' when looking for love in all the loud places

Cornell biologists, who became underwater disc jockeys to study a homely fish that hums, say they have a clue as to how mate selection works. The auditory portion of the midbrain uses the acoustic qualities of all the noise to isolate one signal it is programmed to recognize as potentially interesting.
