Antarctic warming to reduce animals at base of ecosystem, shift some penguin populations southward

...opulations southward down the peninsula as sea ice lessens along its margins," Lyons said. "Gentoo and chinstrap penguins are shifting south into areas now populated by adelie penguins, and the adelies are being forced further south, all because of the change in sea ice." A decrease in sea ice along the ...

Long-lived deep-sea fishes imperiled by technology, overfishing

...n productivity that year. Harvesting older fish lessens the likelihood of many productive breeding years, Heppell pointed out, and lengthens the time species need to recover. "There are models that estimate the recovery time for some rockfish species is at least 200 years," Heppell said. "And we still ...

Researchers seek to design first treatment for neuroAIDS

...IDS, the nerve damage caused by HIV infection that lessens many patients' ability to think and move. As evidence of the progress, researchers at the University of Rochester Medical Center today received a $7 million grant to confirm that two new drug classes can protect the brain from HIV-related nerve damag...

Cardiologist's 'living chip' changes science of disease monitoring

...r means the patient remains healthier, and greatly lessens the chance of a hospital stay. The initial application for this technology is expected to involve pharmaceutical companies, which could use the biological chips to test potential drugs in the lab more quickly and accurately. In later generations, t...

UGA researchers find that hunting can increase the severity of wildlife disease epidemics

Frog’s ear canal may provide insights for understanding human hearing loss

...and fragile eardrum from the environment, but also lessens the distance between the eardrum and the inner ear, thus allowing the bones of the middle ear to be shorter, and as a result, lighter in weight. Scientists have known for several years that A. tormotus males produce high-pitched, birdlike calls that...

Children's taste sensitivity and food choices influenced by taste gene

...d bitter taste sensitivity in some children, which lessens with age. Such a scenario would account for the increase of vegetable consumption that often occurs as children mature into adulthood. This is definitely an area that merits more research." The bitter receptor genotype also predicted children's swee...
