Explore the discoveries that reveal how the world works, alongside the technologies that extend, reshape, and sometimes challenge what’s possible.
Fossils of Australopithecus in a South African cave are one million years older than previously thought. This challenges the consensus that humans first evolved in East Africa.
It is little more than a fancy excuse for escapist fantasizing.
For the very first time, an AR contact lens was worn on the eye of a human subject. And it has about 30 times the pixel density of an iPhone.
The way to understand the earliest moments of creation is to recreate those conditions and study them. Why would we stop now?
It's the "intersection of burnout, imposter syndrome, and anxiety.”
Anxieties about being identified will be superseded by fears of being analyzed.
Sick of remembering a random string of letters, numbers, and special characters?
A successful trial that tested a vaccine against bladder cancer in dogs could help develop a similar one for humans.
The airships have a range of 4,000 nautical miles, can fly for five days, and can cruise as high as 20,000 feet at 80 mph. They take to the skies over Spain in 2026.
The architecture and infrastructure found may well have required the greatest amount of skilled labor of any construction from the same time period in the entire continent.
LIGO can detect the inspirals and mergers of the lowest-mass black holes, but not the biggest ones. Here's how pulsars can help.
An out-of-this-world idea could help reduce some of the risk of solar geoengineering.
Photosynthesis is powerful but very inefficient. Humans can improve on this biochemical process to help the planet.
Two ICU physicians offer a new approach to stopping it.
On Earth, carbon can form millions of compounds, while silicon is largely stuck inside rocks. But elsewhere, silicon could form the basis of life.
There's a fatal prion infection killing deer and elk across North America.
Modern cosmology conjectures different possible fates for the Universe and thus for the end of time. Details depend on which model is right.
More than 90% of human faces are home to mites that live in our skin pores. These friendly guests might be merging with us.
