We’re all getting something that I don’t think any of us wanted: another lesson in real-time virology and epidemiology. I’m referring to the puzzling recent outbreak of monkeypox, which is getting more and more headlines. Add that to the rise in hepatitis cases in children, on top of the continuing (damn it all) coronavirus pandemic, […]
Read MoreIn one of the tallest trees on Earth, a tan, mottled salamander ventures out on a fern growing high up on the trunk. Reaching the edge, the amphibian leaps, like a skydiver exiting a plane. The salamander’s confidence, it seems, is well-earned. The bold amphibians can expertly control their descent, gliding while maintaining a skydiver’s […]

That’s one small stem for a plant, one giant leap for plant science. In a tiny, lab-grown garden, the first seeds ever sown in lunar dirt have sprouted. This small crop, planted in samples returned by Apollo missions, offers hope that astronauts could someday grow their own food on the moon. But plants potted in […]

Read MoreResearchers have documented in a vertical wind tunnel the amazing ability of one species of salamander — which spends its entire life in the tops of redwoods — to parachute, glide and maneuver in mid-air. Ground-dwellers, on the other hand, freak out during free-fall. The salamander’s skydiving skills are likely a way to steer back […]
Read MoreNon-steroidal anti-inflammatory drugs (NSAIDs) such as ibuprofen and aspirin are widely used to treat pain and inflammation. But even at similar doses, different NSAIDs can have unexpected and unexplained effects on many diseases, including heart disease and cancer.
Read MoreDavid McBride, director of NASA’s Armstrong Flight Research Center in California, announced plans to retire on June 30 after 35 years of service to the agency. He began his career at NASA as an intern.

Read MoreCombining multiple carbon nanomaterials in a single substance can yield surprising properties. KAUST researchers have created thin graphite films that could act as high-performance flexible heater panels, reaching several hundred degrees within seconds when a small voltage is applied. They also showed that the key to the material’s exceptional heating performance is graphene domains within […]
Read MoreSingle-walled carbon nanohorns are an allotrope of carbon with promising properties for a variety of applications. Despite their promise, the majority carrier type (i.e., electrons or holes) that defines the electronic properties of this novel semiconductor is poorly understood and so far only indirect measurements have been employed to arrive at contradictory results.
