Artist’s impression of a yellow supergiant in a close binary with a blue, main sequence companion star, similar to the properties derived for the 2019yvr progenitor system in Kilpatrick et al. (2021). If the...

Scientists Invent New Method for Producing Synthetic DNA

PhD Alexander Sandahl, together with Professor Kurt Gothelf, Professor Troels Skrydstrup and a number of students in the groups, has developed a method for efficient and automated production of ingredients for DNA synthesis....

Researchers Identify Genes Associated With Significant Increase in COVID-19 Risk

Having genetic risk variants in the ABO gene might significantly increase the chances of developing COVID-19, and other genes may also increase COVID-19 risk, according to research presented at the ATS 2021 International Conference. Much...

New Immunotherapy “Highly Effective” Against Hepatitis B Virus

Scientists at University College London have identified a new immunotherapy to combat the hepatitis B virus (HBV), the most common cause of liver cancer in the world. Each year, globally, chronic HBV causes an estimated...
