Nature Parks Can Save Species As Climate Changes
Retaining a network of wildlife conservation areas is vital in helping to save up to 90 per cent of bird species in Africa affected by climate change, according to scientists.
New Way To Enhance Stem Cells To Stimulate Muscle Regeneration
Scientists have discovered a powerful new way to stimulate muscle regeneration, paving the way for new treatments for debilitating conditions such as muscular dystrophy. The research shows for the first...
Pig skin cells made to act like stem cells
BEIJING, June 5 (UPI) -- Scientists in China say they've "reprogrammed" skin cells from adult pigs to behave like stem cells from humans.
Hitting Where It Hurts: Exploiting Cancer Cell 'Addiction' May Lead To New Therapies
A new study uncovers a gene expression signature that reliably identifies cancer cells whose survival is dependent on a common signaling pathway, even when the cells contain multiple other genetic...
Shining light on leptin’s role in brain
In investigating the complex neurocircuitry behind weight gain and glucose control, scientists have known that the hormone leptin plays a key role in the process. But within the myriad twists...
Midges keep invasive mosquitoes in check
CHAMPAIGN, Ind., June 4 (UPI) -- U.S. medical entomologists have discovered tiny flies known as midges can be used to control invasive Asian tiger mosquitoes that can carry...
Strategies to Rein in Disease Epidemics Need to be Retooled for Rural Populations, Say Computer Engineers
An infectious disease striking a large city may seem like a disastrous scenario -- millions of people sharing apartment buildings, crammed on buses and trains and brushing past one another...
Shared Motif in Membrane Transport Proteins Found in Plants, Bacteria
University of Arkansas researchers have characterized a membrane receptor protein and its binding mechanism from chloroplasts in plants and determined that it shares a commonly shaped binding site and mechanism...
Aluminium-oxide nanopore beats other materials for DNA analysis

When hosts go extinct, what happens to their parasites?
Hands wring and teeth gnash over the loss of endangered species like the panda or the polar bear. But what happens to the parasites hosted by endangered species? And although...
Squid 'sight': Not just through eyes
It's hard to miss the huge eye of a squid. But now it appears that certain squids can detect light through an organ other than their eyes as well...
Closing the gaps in the human genome
Sequence gaps in human chromosome 15 have been closed by the application of 454 technology. Researchers writing in BioMed Central's open access journal Genome Biology have described a simple and...
'Shunt' makes mice super fat burners
By inserting a molecular shunt into the livers of mice, researchers have shown they can make the animals burn more fat. That so-called glycoxylate shunt consists of two metabolic enzymes...
Semen Quality May Depend Upon Antioxidants In Man's Diet
A possible relationship between men’s diets and the quality of their semen has long been a discussion point. Researchers have now confirmed that antioxidants, molecules which are found mainly in...
