New genetic tool could identify drug targets for diseases associated with metabolic dysfunction

A novel platform for identifying metabolic gene functions has already revealed interactions between proteins and metabolites that are fundamental to cell metabolism.

Asexual reproduction usually leads to a lack of genetic diversity. Not for these ants.

Parthenogenic species must compensate for their limited gene pool or risk extinction.

Researchers capture never-before-seen view of gene transcription

New tech reveals findings that address long-standing theories about how bacteria begin the process of making RNA from DNA.

Light-weight microscope captures large-scale brain activity of mice on the move

With a new microscope that's as light as a penny, researchers can now observe broad swaths of the brain in action as mice move about and interact with their environments.

Surprising origins for a rare cancer

An unexpected discovery may pave the way to better treatments for a broad range of cancers.

What we need to worry about with avian flu—and what we don’t 

Since first detected in birds in 2021, avian flu has killed millions of poultry and infected animals once thought to be immune. What early warning signs could point to an increasing risk for humans?

Key mechanism for maintaining proper telomere length identified 

New findings describe how the enzyme CST is recruited to the end of the telomere, where it maintains telomere length with the help of subtle chemical changes made to the protein POT1.

AI could accelerate drug discovery. But only if we can trust it.

The advent of AlphaFold3 could be an unprecedented boon for drug development. Computational biologist Jiankun Lyu discusses the pros and cons of the tech, and his work analyzing the algorithm.

How memories crystallize over time

“Practice makes perfect” is no mere cliché. It's neuroscience.

Researchers may have found an Achilles heel for hepatitis B

New understanding of how the virus replicates could lead to new therapeutic targets for HBV.
