Himalayan marmots can survive at altitudes up to 5,000 meters in the Himalayan regions of India, Nepal, and Pakistan and on the Qinghai-Tibetan Plateau of China, where many of them face extreme cold, little oxygen, and few other resources....
The pneumonia causing pathogen Pseudomonas aeruginosa has developed a twin-track strategy to colonize its host. It generates two different cells -- motile spreaders and virulent stickers. Researchers at the University of Basel's Biozentrum have now elucidated how the germ...
Scientists from the German Cancer Research Center (DKFZ) and the stem cell institute HI-STEM* in Heidelberg have succeeded for the first time in directly reprogramming human blood cells into a previously unknown type of neural stem cell. These induced...
While examining a skull from an ancient burial ground in a pre-Columbian village in Panama, Nicole Smith-Guzmán, bioarchaeologist at the Smithsonian Tropical Research Institute (STRI), was surprised to discover an example of surfers' ear: a small, bony bump in...
Children born prematurely often develop neuromotor and cognitive developmental disabilities. The best way to reduce the impacts of those disabilities is to catch them early through a series of cognitive and motor tests. But accurately measuring and recording the...
Hundreds of new genes linked to blindness and other vision disorders have been identified in a screen of mouse strains. Many of these genes are likely important in human vision and the results could help identify new causes of...
Current HIV treatments need to be taken for life by those infected as antiretroviral therapy is unable to eliminate viral reservoirs lurking in immune cells. Institut Pasteur scientists have identified the characteristics of CD4 T lymphocytes that are preferentially...
A new compound that inhibits the replication of hepatitis C virus (HCV) in several stages of its lifecycle -- and is also capable of acting on bacteria, fungi and cancer cells -- has been synthesized by researchers at São...
We like to keep the air in our homes as clean as possible, and sometimes we use HEPA air filters to keep offending allergens and dust particles at bay. But some hazardous compounds are too small to be trapped in...
Scientists identified two distinct control mechanisms in the developmental transition of undifferentiated stem cells into healthy brain cells. This fundamental research using mice may inform regenerative medicine treatments for neurodegenerative diseases and spinal cord injuries, in the future. When an...
