Study reveals a universal travel pattern across four continents
Globally, people follow a “visitation law” — an inverse relationship between distance and frequency of visits.
Advance may enable “2D” transistors for tinier microchip components
Atomically thin materials are a promising alternative to silicon-based transistors; now researchers can connect them more efficiently to other chip elements.
Cave deposits show surprising shift in permafrost over the last 400,000 years
Study finds Earth’s frozen surfaces became less susceptible to thawing, potentially locking in more carbon than expected.
How to get salt out of water: Make it self-eject
Crystallizing salts can grow “legs,” then tip over and fall away, potentially helping to prevent fouling of metal surfaces, researchers find.
Cancer cells soften as they metastasize, study suggests
Developing drugs that prevent this softening might impede tumors’ ability to spread.
Fast-spinning black holes narrow the search for dark matter particles
Certain ultralight bosons would be expected to put the brakes on black holes, but new results show no such slowdown.
A safer way to deploy bacteria as environmental sensors
Encapsulating modified bacteria in tough hydrogel spheres prevents them from spreading genes to other microbes.
Study reveals uncertainty in how much carbon the ocean absorbs over time
Climate projections could be off by five years, researchers find.
