DNA strands often 'wiggle' as part of genetic repair

Sometimes, the molecules that make up life exhibit strange behavior. For instance, in simple organisms such as yeast, when genetic material becomes damaged, the affected DNA strands increase their motion, waving about inside ...

New protein gel for tissue regeneration

The human body can repair a lot of tissue damage itself. But sometimes, for instance in case of operations of wounds, it needs help. In her doctoral research, Gosia Wlodarczyk-Biegun developed a protein polymer that provides ...

Scientists identify novel approach to view inner workings of viruses

Since the discovery of the microscope, scientists have tried to visualize smaller and smaller structures to provide insights into the inner workings of human cells, bacteria and viruses. Now, researchers at the National Institute ...

Space radiation is risky business for the human body

While people protect their eyes from the sun's radiation during a solar eclipse, NASA's Human Research Program (HRP) is working to protect the whole human body from radiation in space. Space radiation is dangerous and one ...

New method increases supply of embryonic stem cells

A new method allows for large-scale generation of human embryonic stem cells of high clinical quality. It also allows for production of such cells without destroying any human embryos. The discovery is a big step forward ...
