NewsSeemingly ‘broken’ genes in coronaviruses may be essential for viral survival
Some coronaviruses, including Covid-19 have extra ‘accessory’ genes in addition to the usual minimal viral set and researchers have found that some of these viral genes have stuck around even though they don’t produce a working protein.

NewsResearchers use chemistry modeling software to detect conditions for microbial life on icy worlds
Scientists are working to expand software normally used to model electrolytes and predict corrosion and turn it into a tool that can help determine whether ice-covered worlds have the right conditions for microbial life.

NewsNew imaging approach lifts lid on microbial adhesive interactions
Scientists have identified many types of bacteria in the mouth, but many problems remain in understanding how they work with one another. One of the problems is that microbes assemble themselves into densely packed multi-species biofilms. Their density and complexity pose acute difficulties for visualizing individual cells and analyzing their ...

NewsStudy reveals how microbes create the most toxic form of mercury
Mercury is extraordinarily toxic, but it becomes especially dangerous when transformed into methylmercury – a form so harmful that just a few billionths of a gram can cause severe and lasting neurological damage to a developing fetus. Unfortunately, methylmercury often makes its way into our bodies through seafood – but ...

NewsOptical biosensor rapidly detects monkeypox virus
Researchers have developed an optical biosensor that can rapidly detect monkeypox, the virus that causes mpox. The technology could allow clinicians to diagnose the disease at the point of care rather than wait for lab results.

NewsNew study shows how salmonella tricks gut defenses to cause infection
A new study has uncovered how Salmonella bacteria, a major cause of food poisoning, can invade the gut even when protective bacteria are present.
