US science after a year of Trump: what has been lost and what remains A series of graphics reveals how the Trump administration has sought historic cuts to science and the research workforce.

More than 7800 research grants were terminated or frozen.

Proposed budget cuts of 35% - amounting to US$32 billion.

These are just some of the impacts that Donald Trump's second presidential term have had on science. Read the full story: www.nature.com/immersive/d4...

ADHD is on the rise, but why? The more we learn, the less we seem to understand this condition.

Rates of ADHD have been rising quickly over the past few decades, for reasons that are not entirely clear — a mystery that underscores how much we still have to learn about the condition.

I’m going to halve my publication output. You should consider slow science, too If we don’t slow down, the research enterprise is going to crash, argues Adrian Barnett.

🚨One could argue that we are heading toward a crisis in scientific publishing — and this is something all active researchers, and everyone involved in the research ecosystem, should take time to ponder.

A graphic with a uterus illustration, teal ribbon, and text. Text: "Did You Know? Most cervical cancers are caused by the human papillomavirus (HPV). Regular screening and HPV vaccination can prevent up to 90% of cases, making cervical cancer one of the most preventable cancers."

This week highlights Cervical Cancer Prevention Awareness (Jan 19–25). #OnThisDay, we shine a light on the importance of screening, vaccination, and early detection in preventing cervical cancer. Knowledge saves lives. 💙

During the course of my PhD, I’ve been relearning how to rest Small acts of change have helped me to reset and give myself a break.

People with PhDs say they spent years during their studies feeling exhausted and lost their work–life balance. Ashley Moses shares how small acts of change have helped to reset and relearn how to rest.

Mummified cave cheetahs inform rewilding actions in Saudi Arabia - Communications Earth & Environment Naturally mummified cheetah remains in a Saudi Arabian cave system with radiocarbon-calibrated ages between about 4,200 and 100 years cluster with Asian as well as West-African sub-species, with implications for rewilding efforts, suggests a genomic analysis of the remains.

Seven naturally mummified cheetahs found in caves northern Saudi Arabia show at least two subspecies once roamed the Arabian Peninsula, offering hope for future reintroduction of cheetahs to the peninsula.
