Researchers identify protein that modulates metabolic dysfunction in obesity
— 12:11 GMT | HealthResearchers from Boston University School of Medicine (BUSM) have discovered that Sfrp5, which refers to secreted frizzled-related protein 5, is an anti-inflammatory adipokine whose expression is disrupted in animal models of obesity and type 2 diabetes. The findings, which currently appear on-line in Science, may provide a new way of targeting metabolic disease, specifically obesity…
Carbon dioxide is the missing link to past global climate changes
— 12:08 GMT | EnvironmentIncreasingly, the Earth's climate appears to be more connected than anyone would have imagined. El Nino, the weather pattern that originates in a patch of the equatorial Pacific, can spawn heat waves and droughts as far away as Africa…
Damselfish 'garden' algae
— 12:05 GMT | BiologyA species of damselfish, Stegastes nigricans, selectively weed the algal gardens on which they feed in order to encourage the growth of their preferred algal species of Polysiphonia and suppress the growth of less palatable algae. Researchers writing in the open access journal BMC Evolutionary Biology investigate the feeding preferences of damselfish and explore their diverse gardening systems across the Indo-West Pacific region…
New research shows malaria threat is as old as humanity
— 12:02 GMT | HealthNew research published 17 June by scientists funded by the Biotechnology and Biological Sciences Research Council (BBSRC) shows that malaria is tens of thousands of years older than previously thought. An international team, led by researchers at Imperial College London, have found that the potentially deadly tropical disease evolved alongside anatomically modern humans and moved with our ancestors as they migrated out of Africa around 60-80,000 years ago. The research is published in the journal Current Biology…
New complication seen in stem cell therapy
— 11:59 GMT | HealthFollowing stem cell therapy, an adult patient experienced a new and previously unrecognised complication, which required removal of one of the kidneys, according to a case report appearing in an upcoming issue of the Journal of the American Society Nephrology (JASN). The report suggests that stem cell therapy may cause patients to develop blood vessel and bone marrow masses, the long term effects of which are unknown…
In predominantly black communities, people of all races miss out on kidney care
— 11:56 GMT | HealthRegardless of race, fewer people see a kidney specialist before starting dialysis if they live in predominantly black communities, reports a study appearing in an upcoming issue of the Journal of the American Society Nephrology (JASN). The results highlight the importance of understanding why patients in predominantly black areas are less likely to receive kidney-related care while their kidney function is clearly declining…
