An FDA-approved drug that has been in clinical use for more than 70 years may protect against lung injury and the risk of blood clots in severe COVID-19 and other disorders that cause immune-mediated damage to the lungs, according to a preclinical study.

A young adult in the U.S. could add more than a decade to their life expectancy by changing their diet from a typical Western diet to an optimized diet that includes more legumes, whole grains and nuts, and less red and processed meat, according to a new study. For older people, the anticipated gains to life expectancy from such dietary changes would be smaller but still substantial.

In the world of fundamental particles, you are either a fermion or a boson but a new study shows that one can behave as the other as they move from one place to another.

Researchers have identified a powerful combination of antivirals to treat COVID-19. Combining the drug brequniar with remdesivir or molnupiravir -- both approved by the U.S. Food and Drug Administration for emergency use -- inhibited the SARS-CoV-2 virus in human respiratory cells and in mice.

The presence of pink pumice in the giant pumice raft of the 2012 Havre that drifted across the southwest Pacific Ocean has led researchers to recognize the immense power of underwater volcanic eruptions.

With a surface larger than all the continents together, the Pacific Ocean is the most extreme environment a migratory bird can encounter. Yet there are several bird species that conquer this enormous body of water almost routinely. Migratory bird researchers now provide a synthesis of all the knowns, and especially the many unknowns about the extreme performances of migratory birds such as bar-tailed godwits, whimbrels and red knots, which fly over the Pacific Ocean.

Scientists have revealed that protracted inflammation following COVID-19 is strongly linked to long-term changes in lung structure and function.

During the first wave of the pandemic, patients with COVID-19 who experienced strokes caused by blockage of blood flow to brain tissues were more likely to die or have serious complications compared with non-infected stroke patients, a study finds.
