Eavesdropping comes naturally to young song sparrows

...s were acquired when they were listening to tutors early in life. Beecher thinks the young birds learn more by eavesdropping because it is less threatening than interacting face-to-face with an adult. In a parallel line of research, Beecher and his colleagues are tracking song sparrows by radio in the ...

For many insects, winter survival is in the genes

...rchers report their findings in the current online early edition of the Proceedings of the National Academy of Sciences. Insects and other animals, including humans, produce heat-shock proteins in response to extremely high temperatures. The proteins are so named because they were initially discovered i...

An 'elegant' idea proves its worth 25 years later

...urea cycle disorder, according to Hamosh, who says early and accurate detection can now assure prompt treatment. "We’re teaching all medical students at Hopkins to consider hyperammonemia and immediately do blood tests when they see a combative, lethargic or comatose newborn or child," she says. "The lo...

Arctic ice retreating more quickly than computer models project

...e Arctic.) But newly available data sets, blending early aircraft and ship reports with more recent satellite measurements that are considered more reliable than the earlier records, show that the September ice actually declined at a rate of about 7.8 percent per decade during the 1953-2006 period. "Thi...

Early exposure to indoor fungus molecules may protect infants against future allergies

'Insulator' helps silence genes in dormant herpes virus

...he DNA ladder. "By establishing an insulator in early latency, the Herpes virus can protect this one small region of the genome from silencing, allowing infected cells to survive," says study senior author Jumin Zhou, Ph.D., an associate professor at The Wistar Institute. The findings, appearing in t...

Alien plants attack using 'resource conservation' as weapon, researchers say

...es for fighting invasive species typically involve early detection followed by a variety of removal methods, such as weed-whacking or introducing natural predators of the invasive plants, said study co-author Peter Vitousek, professor of biological sciences at Stanford. To determine which species warran...

First clinical trial of gene therapy for childhood blindness

Professor Ali added: "There are many forms of retinal degeneration, meaning the use of gene therapy treatments must be individually developed then tested in a separate clinical trial specifically for that disease. Howe...

Simple home spit test to spot deadly pre-eclampsia

"This is apparently a fundamental, evolutionarily conserved process in migrating cells. So it clearly has an importan...

Hepatitis E takes a piggyback

...nal BMC Veterinary Research says that pigs get HEV early enough to minimise the risk of human infection. The scenario humans need to worry about would occur if the infection rate in pigs drops. At low infection rates, there is actually a higher chance pigs will pass on HEV to humans at slaughter. Kunio Sa...

DOE JGI sets 'gold standard' for metagenomic data analysis

...s is still in its infancy -- the equivalent of the early days of the California Gold Rush, with labs vying to stake their claim. Amidst the prospecting, the call has been issued for methods to separate fool's gold from the real nuggets. Such a gold standard has now been provided through work led by the...

Thymus transplants gives hope to babies with fatal immune disease

Typically, children remain in the hospital for two to three months after transplantation as physicians work to keep infections at bay as the child's immune system develops.

Heavy multivitamin use may be linked to advanced prostate cancer

While regular multivitamin use is not linked with early or localized prostate cancer, taking too many multivitamins may be associated with an increased risk for advanced or fatal prostate cancers, according to a study in the May 16 issue of the Journal of the National Cancer Institute . Millions of Amer...
