Researchers generate human-monkey chimeric embryos

Investigators in China and the United States have injected human stem cells into primate embryos and were able to grow chimeric embryos for a significant period of timeā€”up to 20 days. The research, despite its ethical concerns, ...

Protecting the genome from transposon activation

Transposons are foreign DNA elements capable of random insertion into the genome, an event that can be very dangerous for a cell. Their activity must be silenced to maintain genomic integrity, which is primarily achieved ...

Bioactive nano-capsules to hijack cell behavior

Many diseases are caused by defects in signaling pathways of body cells. In the future, bioactive nanocapsules could become a valuable tool for medicine to control these pathways. Researchers from the University of Basel ...

Blocking cellular communication stops SARS-CoV-2

In the transmission of signals within the cell which, for example, stimulate cell growth or trigger metabolic processes, phosphate groups play an important biochemical role. The phosphate groups are often attached to proteins ...

Researchers create bioluminescent tag to detect DNA break repair

A new bioluminescent reporter that tracks DNA double stranded break (DSB) repair in cells has been developed by researchers from Massachusetts General Hospital (MGH) and the Academia Sinica in Taiwan. The international team's ...

Evolution in real-time: How bacteria adapt to their hosts

Bacteria that invade animal cells in order to multiply are widespread in nature. Some of these are pathogens of humans and animals. In the environment, they are often found inside unicellular organisms. A research team led ...
