How a dangerous tick-borne virus sneaks into the brain

00:48 New insights into tick-borne encephalitis

Researchers have identified a key protein that helps tick-borne encephalitis virus enter the brain. In rare cases an infection can lead to serious neurological symptoms, but little was known about how the virus interacts with human cells. Now, a team show that a protein found on the outside of cells plays an important role in infection. In mouse experiments, they show that blocking the ability of the virus to bind to this protein protected the mice from disease. Currently no treatments exist, but the team hopes that this research will ultimately lead to a viable drug for this disease.

11:21 How might cancelled NIH grants affect the future of US science?

To assess the potential impact of cuts to funding by the Trump administration, Nature trained a machine-learning bot to try and reproduce the NIH’s method of cancelling grants and applied it to science that was successfully funded around ten years ago. This thought experiment shows that highly impactful science and medical research might have been at risk had a similar process been followed a decade ago, revealing the potentially broad-reaching consequences of these actions today.
