April 1, 2013 10:57 am | News | CommentsResearchers have shown how the innate immune system distinguishes between dangerous pathogens and friendly microbes.
Study Reveals Mutant Histone Mechanism in Brain Cancer
April 1, 2013 10:36 am | News | CommentsMost cancer treatments are blunt. In an attempt to eradicate tumors, oncologists often turn to radiation or chemotherapy, which can damage healthy tissue along with the cancerous growths. New research may bring scientists closer to designing cancer therapeutics that can target tumors with pinpoint accuracy.
Following the Body’s Own Prescription
April 1, 2013 10:22 am | by Cynthia Fox | Articles | CommentsAn intuitive approach, which co-opts the body’s own molecular machinery, has led to massive expansions of umbilical cord blood cells. It and other new approaches “will revolutionize all transplantation,” says University of Minnesota Blood and Marrow Transplantation Director John Wagner.
Code-reading Machinery Collisions Speed Gene Evolution
April 1, 2013 10:18 am | News | CommentsBacteria appear to speed up their evolution by positioning specific genes along the route of expected traffic jams in DNA encoding. Certain genes are in prime collision paths for the moving molecular machineries that read the DNA code, scientists explain.
ALS Discovery Holds Promise for New Treatments
April 1, 2013 10:03 am | News | CommentsScientists said they have evidence from animal studies that a type of central nervous system cell other than motor neurons plays a fundamental role in the development of amyotrophic lateral sclerosis (ALS), a fatal degenerative disease.
Questions in China on Deadly, Lesser-Known Bird Flu
April 1, 2013 7:34 am | by GILLIAN WONG - Associated Press - Associated Press | News | CommentsHealth officials say they still don't understand how a lesser-known bird flu virus was able to kill two men and seriously sicken a woman in China, but that it's unlikely that it can spread easily among humans. Two men in Shanghai became the first known human fatalities from the H7N9 bird flu after contracting it in February.
CDC: E. Coli Outbreak Linked to Frozen Foods
March 29, 2013 6:09 pm | by MIKE STOBBE - AP Medical Writer - Associated Press | News | CommentsHealth officials say at least 24 people have become sick from an outbreak of E. coli infections linked to frozen snack foods marketed to children. No one has died, but eight people, mostly kids or teens, were hospitalized.
Technique Detects ‘Sugar-coated’ Proteins in Blood
March 29, 2013 11:23 am | News | CommentsScientists have developed a new technique that could be used in blood tests to detect a range of age-related conditions such as diabetes, dementia and Alzheimer’s.
Cells, Cell Fragments Move in Opposite Directions
March 29, 2013 11:07 am | News | CommentsLike tiny, crawling compass needles, whole living cells and cell fragments orient and move in response to electric fields— but in opposite directions, scientists have found.
Stem Cell Fate Depends on ‘Grip’
March 29, 2013 10:52 am | News | CommentsA team of researchers has generated new insight on how a stem cell’s environment influences what type of cell a stem cell will become. They have shown that whether human mesenchymal stem cells turn into fat or bone cells depends partially on how well they can “grip” the material they are growing in.
New Vaccine Approach Targets HIV, Other Fast-mutating Viruses
March 29, 2013 10:41 am | News | CommentsA team of scientists has unveiled a new technique for vaccine design that could be particularly useful against HIV and other fast-changing viruses.
Cell Reprogramming During Liver Regeneration
March 29, 2013 10:28 am | News | CommentsResearchers have been able to reprogram cells experimentally, but few have shown that cells can change their identities under normal physiological conditions in the body, particularly in mammals.
Riding the Exosome Shuttle from Neuron to Muscle
March 28, 2013 1:43 pm | News | CommentsImportant new research demonstrates how exosomes shuttle proteins from neurons to muscle cells where they take part in critical signaling mechanisms, an exciting discovery that means these tiny vehicles could one day be loaded with therapeutic agents, such as RNA interference (RNAi), and directly target disease-carrying cells.
