Sculpting complex 3D nanostructures with a focused ion beam

Scientists from the RIKEN Center for Emergent Matter Science and colleagues have developed a new way to fabricate three-dimensional nanoscale devices from single-crystal materials using a focused ion beam instrument. The group used this new method to carve helical-shaped

This new building material pulls carbon out of the air

A new building material developed by engineers at Worcester Polytechnic Institute could change how the world builds. Made using an enzyme that turns carbon dioxide into solid minerals, the material cures in hours and locks away carbon instead of releasing it. It’s strong,

Tiny doses of THC show big benefits for HIV treatment

A new study suggests that micro-doses of THC could help counter many long-term side effects of HIV treatment without causing intoxication. In animal models, low-dose THC reduced inflammation, improved gut bacteria, boosted serotonin, and lowered harmful cholesterol and bile

Drones reveal how feral horse units keep boundaries

For social animals, encounters between rival groups can often lead to conflict. While some species avoid this by maintaining fixed territories, others, like the feral horses, live in a "multilevel society" where multiple family groups (units) aggregate to form higher level

Print Edition 65: The Food Issue

Issue 65 of the Nautilus print edition combines some of the best content from our November and December 2025 online issues, and a special Food section. It includes contributions from animal rights activist Peter Singer, science writer Amanda Gefter, evolutionary biologist David

SunRISE SmallSats ace tests, moving closer to launch

When the six tiny spacecraft of NASA's SunRISE (Sun Radio Interferometer Space Experiment) mission settle into their orbits high above Earth after launching later this year, they'll function as one giant radio dish to track the rumbles of radio bursts coming from deep within

Q&A: Why Philly has so many sinkholes

In early January, a giant sinkhole formed at an intersection in the West Oak Lane neighborhood of North Philadelphia after a water main break. Just two weeks earlier, the city reopened a section of the Schuylkill River Trail in Center City that had been shut down for two months
