RNA work that led to COVID-19 vaccines wins 2023 Nobel in medicine
Katalin Karikó and Drew Weissman overcame hurdles to using mRNA for medicine. This led to COVID vaccines — and maybe, one day, some for other infections.

Neuroscientists decoded a song from brain activity
The technique could help improve communication devices for people who are unable to speak.
- Animals
This massive ancient whale may be the heaviest animal ever known
Called Perucetus colossus, it may have tipped the scales at up to 340 metric tons — more than today’s blue whales.

This egg-eater may have the biggest gulp of any snake its size
Slither aside, Burmese pythons. This little African snake has a truly outsized swallow.
- Brain
A rat’s playfulness relies on cells in one part of its brain
Certain cells here control its behavior. Studying this circuitry could also help us understand depression in people.
- Animals
A new technique creates glowing whole-body maps of mice
Removing cholesterol from mouse bodies lets fluorescent proteins seep into every tissue. That has helped researchers map entire body parts.
- Agriculture
Crops are being engineered to thrive in our changing climate
Plants are already the best carbon catchers on Earth. New research could make them even better.
- Animals
Toothed whales use their noses to whistle and click
Much as people do, toothed whales, such as dolphins and sperm whales, make noises in three different vocal registers.
- Agriculture
Cow dung spews a climate-warming gas. Adding algae could limit that
But how useful this is depends on whether cows eat the red algae, a type of seaweed — or it gets added to their wastes after they’re pooped out.
- Fossils
New fossils bring the wide world of pterosaurs to life
The latest clues from fossils hint at where these flying reptiles came from, how they evolved, what they ate and more.

Let’s learn about beetles’ survival superpowers
Some beetle species can survive extreme pressure, dehydration or even getting eaten.
