- Quantum Physics
Quantum mechanics means some black hole orbits are impossible to predict
Computer simulations reveal that foreseeing the paths of three orbiting objects sometimes requires precision better than the quantum limit.
- Chemistry
Beets bleed red but a chemistry tweak can create a blue hue
A new blue dye derived from beet juice might prove an alternative to synthetic blue dyes in foods, cosmetics or fabrics.
- Humans
It’s time to stop debating how to teach kids to read and follow the evidence
Most children need help learning to read, but there’s long-standing disagreement on how best to help them. Decades of research have identified the most effective approaches.
- Animals
The ‘insect apocalypse’ is more complicated than it sounds
Freshwater arthropods trended upward, while terrestrial ones declined. But the study’s decades of data are spotty.
- Animals
Australian fires have incinerated the habitats of up to 100 threatened species
Hundreds of fires that are blazing across the continent’s southeast have created an unprecedented ecological disaster, scientists say.

Gene-editing tool CRISPR wins the chemistry Nobel
A gene-editing tool developed just eight years ago that has “revolutionized the life sciences” nabbed the 2020 Nobel Prize in chemistry.
- Animals
Green darner dragonflies migrate a bit like monarch butterflies
Some dragonflies do a north-south annual migration that takes at least three generations.
- Animals
Collectors find plenty of bees but far fewer species than in the 1950s
An analysis of global insect collections points to a major collapse in bee diversity since the 1990s.

Slow sperm may fail at crashing ‘gates’ on their way to an egg
A new study describes how sperm navigate narrow straits in the reproductive tract’s obstacle course to reach an egg.
- Planetary Science
How upcoming missions to Mars will help predict its wild dust storms
Predicting the weather on Mars is essential for landing and keeping rovers — or astronauts — safe on the surface. The next Mars missions will give forecasts a boost.
- Animals
Each year painted lady butterflies cross the Sahara — and then go back again
Painted ladies migrate the farthest of any butterfly.
- Physics
Andrea Young uncovers the strange physics of 2-D materials
Physicist Andrea Young has set his sights on the strange ways electrons behave in flat, layered structures.
