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Anxieties about being identified will be superseded by fears of being analyzed.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.

From the explosions themselves to their unique and vibrant colors, the fireworks displays we adore require quantum physics.
Before gunpowder was introduced to the West, medieval Arabs devised grenades using crockery.
On July 4, we celebrate the tenth anniversary of the discovery of the Higgs boson, the missing piece of the Standard Model of particle physics.
1859's Carrington event gave us a preview of how catastrophic the Sun could be for humanity. But it could get even worse than we imagined.
Does memory start to work only at a certain age?
Your eyes are playing tricks on you.
The idea of gravitational redshift crossed Einstein's mind years before General Relativity was complete. Here's why it had to be there.
Since at least 600 BC, people have been mesmerized by the concept of the infinite.
