Scripps Research chemist devises new method to quantify protein changes
— 14:36 GMT | ChemistryA scientist from the Florida campus of The Scripps Research Institute has devised a new method of analysing and quantifying changes in proteins that result from a common chemical process. The new findings could provide new insights into the effects of a highly destructive form of stress on proteins in various disease models, particularly cancer…
When less is more: How mitochondrial signals extend lifespan
— 14:33 GMT | HealthIn making your pro-longevity resolutions, like drinking more red wine and maintaining a vibrant social network, here's one you likely forgot: dialling down your mitochondria. It turns out that slowing the engines of these tiny cellular factories could extend your life-an observation relevant not only to ageing research but to our understanding of how cells communicate with each another…

Princeton scientists construct synthetic proteins that sustain life
— 14:27 GMT | BiologyIn a groundbreaking achievement that could help scientists 'build' new biological systems, Princeton University scientists have constructed for the first time artificial proteins that enable the growth of living cells…
Stem cell discovery could lead to improved bone marrow transplants
— 14:24 GMT | HealthResearchers at the University of California, Santa Cruz, have identified a key molecule for establishing blood stem cells in their niche within the bone marrow. The findings, reported in the January issue of Cell Stem Cell, may lead to improvements in the safety and efficiency of bone marrow transplants…
Neural stem cells maintain high levels of reactive oxygen species, UCLA study finds
— 14:21 GMT | HealthFor years, the majority of research on reactive oxygen species (ROS) - ions or very small molecules that include free radicals - has focused on how they damage cell structure and their potential link to stroke, cardiovascular disease and other illnesses…
Genetic abnormalities identified in pluripotent stem cell lines
— 14:18 GMT | HealthA multinational team of researchers led by stem cell scientists at the University of California, San Diego School of Medicine and Scripps Research Institute has documented specific genetic abnormalities that occur in human embryonic (hESC) and induced pluripotent stem cell (iPSC) lines. Their study, 'Dynamic changes in the copy number of pluripotency and cell proliferation genes in human ESCs and iPSCs during reprogramming and time in culture' will be published in the January 7 issue of the journal Cell Stem Cell…
'Long-shot' discovery may lead to advances in treating anxiety, memory disorders
— 14:15 GMT | HealthAn unexpected discovery by UCLA life scientists holds promise for the future development of treatments for post-traumatic stress disorder and other anxiety disorders, and potentially for Alzheimer's disease and other memory-impairment diseases…
