CRISPR screen identifies gene that helps cells resist West Nile, Zika viruses
Researchers now report the first use of CRISPR genome-wide screening to identify a gene that helps cells resist flavivirus infection.

E. coli's adaptation to extreme temperatures helps explain resistance to certain drugs
A new study suggests that defenses against extreme temperatures give E. coli bacteria an advantage in fending off certain drugs. The work could help doctors administer antibiotics in a more precise way.

Targeting this key bacterial molecule could reduce the need for antibiotics
Scientists have shown that cellulose serves a mortar-like role to enhance the adhesion of bacteria to bladder cells, causing urinary tract infections.

Newly discovered enzyme is 'firing pin' for plant immunity
Just like humans, plants have an immune system that helps them fight off infections. Researchers have now identified a key step in how plant cells respond to pathogens -- a family of kinase enzymes that activate the enzymes that make reactive oxygen.

Mapping vast unknown territory of long non-coding RNA
Scientists have developed a powerful method for exploring the properties of mysterious molecules called long non-coding RNAs (lncRNAs), some of which have big roles in cancer and other serious conditions.

Why some tuberculosis bacteria prove deadly
A new study has found that the same mutation that gives tuberculosis bacteria drug resistance also elicits a different -- and potentially weaker -- immune response.

Machine learning technique to predict human cell organization
Scientists have used machine learning to train computers to see parts of the cell the human eye cannot easily distinguish.

How plants harness microbes to get nutrients
Scientists have discovered how plants harness microbes in soil to get nutrients, a process that could be exploited to boost crop growth, fight weeds and slash the use of polluting fertilizers and herbicides.

Viruses under the microscope
Human herpesviruses such as HHV-6 can remain dormant in cells for many years without being noticed. When reactivated, they can cause serious clinical conditions. Researchers have now found a way of differentiating between active and inactive viruses.
