Rats infected as newborns grew up vulnerable to memory problems during an immune challenge

Underscoring the value of good prenatal care, new research suggests that early infection may create a cognitive vulnerability that appears later during stress on the immune system. Researchers at the University of Colorado at Boulder have reported that rats who experienced a one-time infection as newborns didn't learn as well as adult rats who were not infected as pups, after their immunity was c...

Low level of extinction during ice age linked to adaptability

A Johns Hopkins University graduate student may have figured out why rates of extinction were so low for many of the major groups of marine life during one of the greatest ice ages of them all, which occurred from about 330 million to 290 million years ago, late in the Paleozoic Era. The likely answer: because those aquatic life forms that did survive during this era were singularly equipp...

Key mechanism in genetic inheritance during cell division identified

A key mechanism in the passing of genetic material from a parent cell to daughter cells appears to have been identified by a team of Berkeley researchers. Their study may explain how a complex of proteins, called kinetochores, can recognize and stay attached to microtubules, hollow fibers in the walls of biological cells that are responsible for the faithful segregation of chromosomes during cell...

Too much water may be as dangerous as too little during long-distance athletic events
