Repurposed antibiotic may be an effective therapeutic in COVID-19 infected mice
Repurposed drugs may have a speedier path to clinical use because they have already been shown to be safe in people. A new study suggests clofoctol may be an effective treatment for SARS-CoV-2 infections in mice.
Scientists reveal how seascapes of the ancient world shaped genetic structure of European populations
Scientists have explored the importance of sea travel in prehistory by examining the genomes of ancient Maltese humans and comparing these with the genomes of this period from across Europe. Previous findings from the archaeological team had suggested that towards the end of the third millennium BC the use of...
Watch dolphins line up to self-medicate skin ailments at coral ‘clinics’
If a human comes down with a rash, they might go to the doctor and come away with some ointment to put on it. Indo-Pacific bottlenose dolphins get skin conditions, too, but they come about their medication by queuing up nose-to-tail to rub themselves against corals. Researchers now show that...

Researchers find another layer to the code of life
A new examination of the way different tissues read information from genes has discovered that the brain and testes appear to be extraordinarily open to the use of rare codons to produce a given protein. Testes of both fruit flies and humans seem to be enriched in protein products of...
Why baby leatherback marine turtles can’t ‘see the sea’
For most sea turtles, the journey to find the ocean from their nests is pretty straightforward. However, leatherback hatchlings more often crawl around in circles trying to find the ocean. Circling delays their entry into the ocean, wastes energy, and places them at greater danger from natural predators. Under different...
