The cytoskeleton is a structure that not only helps cells maintain their shape and internal organisation, but also enables them to perform functions like movement and migration to sites far from the place where they originated. ...
Since most of the microbes in our gut are bacteria, they tend to hog much of the microbiome research limelight. But lurking amongst the bacteria are other microbes such as single-cell eukaryotes (SCE) and viruses, which have ...
The largest ever catalog of bacterial and archaeal microbes commonly populating the human body across worldwide populations has been assembled. This is the main result of a new study coordinated by Nicola Segata and Edoardo ...

Scientists have shown that different segments of a virus genome can exist in distinct cells but work together to cause an infection.
The nucleus is a treasure trove of biological information that keeps the cell—and thus living organisms—ticking. But many processes within the nucleus remain a mystery to scientists.
The TMEM16 family of membrane proteins was hailed as representing the elusive calcium-activated chloride channels. However, the majority of the family members turned out to be scramblases, proteins that shuffle lipids between ...
Insects are critical contributors to ecosystem functioning, and like most living organisms their co-evolution with microbes has been essential to support these functions. While many insects are infamous for wreaking havoc ...
