How a dangerous tick-borne virus sneaks into the brain

Sep 24, 2025

Jack Leeming, Chief Editor of Nature Careers, dives into the intriguing world of machine learning and its impact on US grant cancellations. He discusses how his team used AI to simulate NIH funding cuts, revealing that high-impact research could have faced dire consequences. Additionally, the conversation touches on the surprising reactions from researchers about the potential loss of crucial projects. Leeming emphasizes the need for transparency in grant decisions and the implications for the future of scientific funding.

INSIGHT

TBE Uses A Distinct Entry Route

LRP8 appears important for tick-borne encephalitis specifically, not for all flaviviruses.
This specificity suggests distinct entry mechanisms underlie differing disease outcomes.

ADVICE

Target Receptor To Develop Treatments

Use receptor-targeting strategies to develop antiviral drugs against TBE.
Consider inhibitors of binding or downstream receptor activation as therapeutic routes.

INSIGHT

Soft Robot Speeds Emergency Intubation

A soft robot autonomously guides an airway tube faster and with higher first-pass success.
After minimal training, clinicians performed intubation more quickly and reliably on cadavers.

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.
