Lassa fever kills thousands of people in West Africa each year, yet many cases go undiagnosed before it’s too late. A Lancet study suggests the true scale of infection may be far higher than official figures show.

When Neanderthals and ancient modern humans interbred, the pairings were mostly between male Neanderthals and female humans, according to a new Science study.
This finding helps explain why Neanderthal ancestry present in most humans is unevenly distributed. https://scim.ag/4cQYpIL

Next pandemic is gonna be lit 🔥
We’ll all be chugging protein drinks and swallowing deworming tablets and talking about “that which cannot be named” while our social media feeds tell us that anyone who died did not do enough push-ups…
#NIH to deprioritize pandemic preparedness and biodefense research, @nature.com reports, saying director Jay Bhattacharya wants to focus on known diseases, not possible future threats.
What could possibly go wrong?

Hello world. One of my favorite fun facts to share about elephants…their trunks are covered in whiskers, with built-in intelligence! If that got your attention…check out our new paper in @science.org www.science.org/doi/10.1126/...
How could a simple self-replicating system emerge at the origins of life? RNA polymerase ribozymes can replicate RNA, but existing ones are so large that their self-replication seems impossible. Could they be smaller?
Excited to share our latest work in @science.org on a new small polymerase.

Five years after the rollout of Covid-19 vaccines started, it seems the mystery of why the Astra-Zeneca and J&J vaccines led to a rare but deadly side effect of unusual blood clots and bleeding has finally been solved.
It's a fascinating case of molecular mimicry that may help make vaccine safer.🧪
Study finds no link between COVID-19 vaccines and autism
A new study finds no increase in autism rates in babies born to mothers who received COVID-19 vaccines just before or during pregnancy, compared with children of unvaccinated moms.

Australia is battling its biggest rise in whooping cough cases in 35 years. Also known as pertussis or the “100-day cough”, whooping cough is a potentially fatal respiratory illness which causes severe coughing episodes.
So why the surge? The Conversation UK explores: bit.ly/3Mbkl6L
