In all, the researchers observed 10 traditions spread throughout the chimpanzee groups at the Yerkes Research Center and the University of Texas. “This study nicely summarizes our collaborative work of the last five years, ...

'Lucky 13' as new gene discovery offers further hope for childhood blindness

...esting possible cures for inherited blindness, its becoming very important for everybody to know exactly which mutation they've got, because the treatments being tested are specific for different kinds of retinal degeneration. All in all its an exciting time for eye research and a very promising one for peopl...

Undergraduate research shows leaderless honeybee organizing

...- reducing her food intake, slowing egg laying and becoming more active. At this point, the workers begin to send a second signal that researchers call “worker piping” at a fevered pitch. Piping, which consists of bees making contact and vibrating their wing muscles rapidly, appears to be a general instructio...

University of Pittsburgh School of Medicine researchers develop 'off-the-shelf' vascular grafts

... preferred conduits because they are less prone to becoming obstructed. However, they are in very limited supply, as many patients require multiple grafts. Thus, there is an ongoing search for the ideal small-caliber arterial substitute for revascularization procedures. The University of Pittsburgh team, l...

How 'memory' T cells curb the spread of viruses throughout the body

...nst the spread of an invading virus occurs. After becoming sick from many viruses, the body becomes “immune” (protected) from recurrence of the same disease. This is why before vaccines were developed, childhood diseases such as measles and mumps occurred only once in a lifetime. The immunity occurs when t...

'Virtual autopsy' helps identify drowning as cause of death

Autopsy findings that support the diagnosis of drowning include but are not limited to frothy fluid in the airways or lungs, hyperinflated and congested lungs, and fluid in the paranasa...

Fuel from fiber -- Pretreatment can put corn stalks, trees in your car's tank

... making fuels from poplar trees and corn stalks is becoming more efficient and cost-effective. Dale is internationally known for his 30 years of research on making ethanol from plant biomass ?the stems, leaves, stalks and trunks of plants and trees usually discarded as waste after a crop is harvested. He's...

New knowledge improves rice quality

...sponse we got to the workshop that rice quality is becoming a very hot topic in rice research almost everywhere," the convener and head of IRRI’s Grain Quality, Nutrition, and Postharvest Center, Melissa Fitzgerald, said. "Many of the issues we discussed may not have even been considered a few years ago, but,...

In addition, less infamous herpes viruses like HHV6 and HHV7 permanently infect most humans without ever producing any significant symptoms. The results have potentially wide-reaching implications for immune research. Humans and o...

Effect on breast tumors of DNA alternations in 3 genes described

...st author on the study. "In addition, it is now becoming clear that other changes in the DNA may also contribute to the development of cancer." The researchers analyzed methylation status in three genes, known as E-cadherin, p16 and retinoic acid B2 receptor (RAR-B2), using tissue samples from 887 brea...

Discovery of new cave millipedes casts light on Arizona cave ecology

Their results show that a rarer cell type that links collections of pyramid cells ?called a Martinotti cell ?acts as a kind of safety device. When a Martinotti cell receives signals above a certain frequency, it responds by sending ba...
