What will astronauts need to survive the dangerous journey to Mars?
Going to Mars, astronauts will need protections from microgravity and radiation, plus miniature medical devices to diagnose problems and help handle emergencies.
- 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.

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.

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.
- 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.
- 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.

How thin, delicate butterfly wings keep from overheating
Structures in butterfly wings help living tissues such as veins release more heat than the rest of the wing.

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.

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.
- Neuroscience
Mice watching film noir show the surprising complexity of vision cells
Only about 10 percent of mice’s vision cells behaved as researchers expected they would, a study finds.

Gene editing can make fruit flies into ‘monarch flies’
Just three molecular changes can make fruit flies insensitive to milkweed toxins.

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.
