New collaborative research reveals chimpanzees can sustain multiple-tradition cultures

...embers of the international collaborative research team taught forms of tool use and food extraction techniques to high-ranking individuals in four different captive chimpanzee communities. Researchers then observed as those individuals passed on the techniques to other members of their communities. The r...

Stroke study sheds light on left-right brain divide

...cts of language, decision making and learning. The team found that people who had damage to their left side were more likely to realise they had made a mistake, and then correct it, compared to those who had damage to their right frontal lobes. Funded by the Wellcome Trust, the research is now published i...

Rising skin cancer rates are more likely to affect wealthy people, says 12-year review

...gnant melanomas and basal cell carcinomas.” The team looked at data collected by the Northern Ireland Cancer Registry, at Queen’s University Belfast, from 1993 to 2004, analysing the records of patients diagnosed with the three most common skin cancers. They found that men were 30 per cent more lik...

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

An international research team has discovered a gene that, when mutated, causes one of the most common forms of inherited blindness in babies. Scientists at the University of Leeds, working in collaboration with experts from other centres around the world, identified the gene, whi...

Migration alert -- How tumor cells home in on the lymphatic system

A Swiss-based research team has published a new mechanistic description of how tumor cells migrate to the lymphatic system in the early stages of tumor metastasis. This new understanding holds significant potential for developing anti-metastasis therapies. Scientists know tha...

Researchers examine carbon capture and storage to combat global warming

... at storage in deep saline aquifers. A Stanford team also has begun researching storage of carbon dioxide in deep coal beds. In coal, chemical bonds form between the carbon dioxide and the coal, making the method potentially more secure than others, the researchers said. Even better, the process can...

Newly discovered antibody may be body's natural defense against Alzheimer's

...at Weill Cornell Medical College. Dr. Relkin's team has been testing an antibody-based immunotherapy called Intravenous Immunoglobulin (IVIG) as a potential new treatment for Alzheimer's. IVIG is made from the blood of healthy donors and was previously reported to contain small quantities of antibodie...

Researchers reveal structure of protein altered in autism

...mplicated in autism spectrum disorders, a research team led by scientists at the University of California, San Diego (UCSD) Skaggs School of Pharmacy and Pharmaceutical Sciences has discovered how particular genetic mutations affect this complex and contribute to the developmental abnormalities found in c...

Dr Taylor and his team are now testing the ability of HDAC6 to prevent neurodegeneration in several mouse models, including motor neuron disease, Parkinson’s disease, and Huntington’s disease. They are also attempting to identify pharmacologic approaches to augmenting HDAC...

Herpes virus hijacks DNA repair process

Ms Thys and her team decided to study a gene called TGBF1 which they already knew had non-genetic indications of involvement in otosclerosis: it plays a role during embryonic development of the ear and is expressed in otosclerotic bone. They used SNP (single nucleotide ...
