New research led by University of Pennsylvania biologists and published this week in the journal Nature Genetics has identified small sequences in plant DNA that act as signposts for shutting off gene activity, directing the placement of proteins that silence gene expression.
In a new pair of papers, researchers from MIT's Computer Science and Artificial Intelligence Laboratory (CSAIL) explore ways for computers to help doctors make better medical decisions.
Allina Health researchers say individuals in Heart Safe Communities who suffer out-of-hospital cardiac arrests (OHCA) are four times more likely to receive chest compressions (CPR) and twice as likely to have automated external defibrillators (AEDs) placed by bystanders and first responders before EMS personnel arrive, according to a Minnesota study published in the August issue of the journal, Resuscitation.
For the first time, researchers are using proteomics to examine proteins and peptides in saliva in order to accurately detect exposure to Zika virus. With 70 countries and territories reporting evidence of mosquito-borne Zika virus transmission, there is an increased need for a rapid and effective test for the virus. This study, published online today in the Journal of Dental Research (JDR), offers a new, quicker and more cost-effect way to test for the virus.
Scientists have pinpointed how a tiny protein seems to make the deadly Ebola virus particularly contagious.
University at Buffalo researchers have assembled a team of three antibiotics that, together, are capable of eradicating E. coli carrying mcr-1 and ndm-5 -- genes that make the bacterium immune to last-resort antibiotics.
Fewer trips to the dentist may be in your future, and you have mussels to thank.
Researchers have revealed the existence of a new quorum-sensing molecule that increases the virulence of the pathogenic bacterium Pseudomonas aeruginosa.
Not much is known about stem cell metabolism, but a new study from the Children's Medical Center Research Institute at UT Southwestern has found that stem cells take up unusually high levels of vitamin C, which then regulates their function and suppresses the development of leukemia.
Gut microbes have been in the news lately. Recent studies show they can influence human health, behavior, and certain neurological disorders, such as autism. But just how do they communicate with the brain? Results from a new study suggest a pathway of communication between certain gut bacteria and brain metabolites, by way of a compound in the blood known as cortisol. And unexpectedly, the finding provides a potential mechanism to explain the characteristics of autism.
