Methanol fuel gives this tiny beetle bot the freedom to roam
A new robot insect uses energy-dense methanol as fuel, not batteries. It could be a blueprint for future search-and-rescue bots with long run times.

How some superblack fish disappear into the darkness of the deep sea
Some fish that live in the ocean’s depths are superblack as a result of a special layer of light-absorbing structures in the skin.

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

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.
- 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.

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.

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.

Green darner dragonflies migrate a bit like monarch butterflies
Some dragonflies do a north-south annual migration that takes at least three generations.

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.
