Caltech neuroscientists find brain region responsible for our sense of personal space
— 31 Aug 2009 | HealthIn a finding that sheds new light on the neural mechanisms involved in social behaviour, neuroscientists at the California Institute of Technology (Caltech) have pinpointed the brain structure responsible for our sense of personal space…
Researchers identify protein involved in causing gum disease, osteoporosis, arthritis
— 31 Aug 2009 | HealthInvestigators at Hospital for Special Surgery, collaborating with researchers from other institutions, have contributed to the discovery that a gene called interferon regulator factor-8 (IRF-8) is involved in the development of diseases such as periodontitis (gum disease), rheumatoid arthritis and osteoporosis. The study, which was published online 30 August, ahead of print, in the journal Nature Medicine, could lead to new treatments in the future…
MSU researchers improve zebrafish cloning methods
— 31 Aug 2009 | BiologyA team of Michigan State University researchers has developed a new, more efficient way of cloning zebra fish, a breakthrough that could have implications for human health research…
Counting duplicated genome segments now possible
— 31 Aug 2009 | BiologyA newly designed computational method has proven its usefulness in counting copies of duplicated genome sequences and in doing initial assessments of their contents, according to a study published 30 August in Nature Genetics. The number of copies of particular DNA segments can differ from one person to the next…
High HIV infection rate among Soweto Township gays
— 31 Aug 2009 | HealthNew research from UCSF examining HIV among men who have sex with men (MSM) in the township of Soweto in South Africa has found that a third of gay-identified men are infected with HIV…

New hope for deadly childhood bone cancer
— 31 Aug 2009 | HealthResearchers at Huntsman Cancer Institute (HCI) at the University of Utah have shed new light on Ewing's sarcoma, an often deadly bone cancer that typically afflicts children and young adults. Their research shows that patients with poor outcomes have tumours with high levels of a protein known as GSTM4, which may suppress the effects of chemotherapy. The research is published online today in the journal Oncogene…
Air pollution is reducing the amount of rain in China
— 31 Aug 2009 | EnvironmentAir pollution in eastern China during the last 50 years has led to a reduction in the amount of light rainfall of almost a quarter. This is revealed by an international study conducted with support from the University of Gothenburg, Sweden. There is a risk that the consequences will be increased drought, reduced harvests and poorer public health…
Researchers create world's smallest semiconductor laser
— 30 Aug 2009 | TechnologyResearchers at the University of California, Berkeley, have reached a new milestone in laser physics by creating the world's smallest semiconductor laser, capable of generating visible light in a space smaller than the size of a single protein molecule…
Study reveals new genetic culprit in deadly skin cancer
— 30 Aug 2009 | HealthDrawing on the power of DNA sequencing, National Institutes of Health researchers have identified a new group of genetic mutations involved in the deadliest form of skin cancer, melanoma. This discovery is particularly encouraging because some of the mutations, which were found in nearly one-fifth of melanoma cases, reside in a gene already targeted by a drug approved for certain types of breast cancer…
