Annotation tool provides step toward understanding links between disease, mutant RNA
Researchers have developed a computer program that represents a key step toward better understanding the connections between mutant genetic material and disease.

Researchers discover how body temperature wrecks potential dengue, Zika vaccine
A major route toward creating effective vaccines against dengue virus and Zika involves the E protein that covers the surface of each viral particle. But creating such a vaccine has proven difficult for a number of reasons. Now researchers have delineated the details of one major barrier to a promising vaccine. It's something we all have -- a natural body temperature of about 98.6 degrees.

New insights into malaria parasite
Scientists have found that various stages of the development of human malaria parasites, including stages involved in malaria transmission, are linked to epigenetic features and how chromatin -- the complex of DNA and proteins within the nucleus -- is organized and structured in these parasites.

E. coli tailored to convert plants into renewable chemicals
Jet fuel, pantyhose and plastic soda bottles: all three could be made from bioengineered bacteria.

Insect gene allows reproductive organs to cope with harmful bacteria
A group of biologists has studied Nasonia parasitic wasps, which are about the size of a sesame seed, and they serve as one of the best models to dissect and characterize the evolution of insect genomes.

What bacteria can teach us about combating atrazine contamination
Researchers are interested in harnessing the bacterial ability to degrade atrazine in order to remediate atrazine-polluted environments. They now describe previously unknown proteins involved in atrazine degradation.

More than a living syringe: Mosquito saliva alone triggers unexpected immune response
Mosquito saliva alone can trigger an unexpected variety of immune responses in an animal model of the human immune system.

Battling bubbles: How plants protect themselves from killer fungus
In the battle between plants and pathogens, molecules called small RNAs are coveted weapons used by both invaders and defenders. Researchers report how plants package and deliver the sRNAs they use to fight back against plant pathogens. The study focused on Botrytis cinerea, a fungus that causes a grey mold disease in strawberries, tomatoes, and almost all fruits, vegetables, and many flowers.

Blood type affects severity of diarrhea caused by E. coli
A new study shows that a kind of E. coli most associated with 'travelers' diarrhea' and children in underdeveloped areas of the world causes more severe disease in people with blood type A. The bacteria release a protein that latches onto intestinal cells in people with blood type A, but not blood type O or B, according to a new study.

How immune cells kill bacteria with acid
The first line of immune defense against invading pathogens like bacteria are macrophages, immune cells that engulf every foreign object that crosses their way and kill their prey with acid. However, it is not yet entirely understood how the acidification process is established. In their quest to systematically study proteins that transport chemicals across cellular membranes, researchers characterized the critical role for transporter SLC4A7, providing valuable new insights for many pathologic conditions.
