Scientists discover new rules about 'runaway' transcription

On the evolutionary tree, humans diverged from yeast roughly 1 billion years ago. By comparison, two seemingly similar species of bacteria, Escherichia coli and Bacillus subtilis, have been evolving apart for roughly twice ...

Why does COVID-19 impact only some organs, not others?

In severe cases of COVID-19, damage can spread beyond the lungs and into other organs, such as the heart, liver, kidney and parts of the neurological system. Beyond these specific sets of organs, however, the virus seems ...

Droplet spread from humans doesn't always follow airflow

The World Health Organization has warned that aerosol transmission of COVID-19 is being underestimated. If aerosol spread is confirmed to be significant, as suspected, we will need to reconsider guidelines on social distancing, ...

Cell competition in the thymus is crucial in a healthy organism

T lymphocyte cells develop in the thymus. They are essential for fighting infections and preventing cancer. The thymus is located just above the heart. It is large in children and gradually reduces in size with age. In the ...

An open-source data platform for researchers studying archaea

Bioinformatics and big data analyses can reap great rewards for biologists, but it takes a lot of work to generate the datasets necessary to begin. At the same time, researchers around the globe churn out datasets that could ...

Study finds less impact from wildfire smoke on climate

New research revealed that tiny, sunlight-absorbing particles in wildfire smoke may have less impact on climate than widely hypothesized because reactions as the plume mixes with clean air reduce its absorbing power and climate-warming ...

Researchers construct dynamic landscape of medaka embryogenesis

Medaka, a fish, has become an important vertebrate model widely used in genetics, developmental biology, environmental sciences, and many other fields. A high-quality genome sequence and a variety of genetic tools are available ...

Arctic Ocean acidification worse than expected

The Arctic Ocean will take up more CO2 over the 21st century than predicted by most climate models. This additional CO2 causes a distinctly stronger ocean acidification. These results were published in a study by climate ...
