Many human genomes shaped by past events that caused sharp dips in the population
The genomes of many human populations show evidence of founder events, which occur when a small number of initial members start a new population, and can lead to low genetic diversity as well as increase the risk of certain genetic diseases in the ne.....»»
Stiffness and viscosity of cells found to differ in cancer and other diseases
During illness, the stiffness or viscosity of cells can change. Tom Evers demonstrated this by measuring such properties of human immune cells for the first time. "The stiffness of certain cells could be a way to make a diagnosis," Evers said......»»
AI can help researchers understand what viruses are up to in the oceans and in your gut
Viruses are a mysterious and poorly understood force in microbial ecosystems. Researchers know they can infect, kill and manipulate human and bacterial cells in nearly every environment, from the oceans to your gut. But scientists don't yet have a fu.....»»
Researchers discover new family of bacteria with high pharmaceutical potential
Most antibiotics used in human medicine originate from natural products derived from bacteria and other microbes. Novel microorganisms are therefore a promising source of new active compounds, also for the treatment of diseases such as cancer or vira.....»»
