If you’re a massless particle, you must always move at light speed. If you have mass, you must go slower. So why aren’t any neutrinos slow?
This is a time for family and friends to gather, watch the full moon and eat mooncakes and other delicacies.
The search for worlds outside our solar system has just turned up a planet, TOI-2257 b, with a truly extreme orbit.
Though these ancient settlers of China were culturally cosmopolitan, their DNA turns out to have been completely distinct from the communities with which they interacted.
This marks a historic moment in humanity’s relationship to the planet.
Rock art in northern Australia depicts marsupial lions, giant kangaroos, and other megafauna that populated the Land Down Under long ago.
What was this mammoth tusk doing on the ocean floor 150 miles from land?
Massive objects like black holes, stars, and rogue planets routinely pass near our Solar System. An ensuing comet storm could destroy us.
Finding alien technology on the seafloor would be truly incredible. This extraordinary claim, however, is debunked by the actual evidence.
The dark genome makes up 98% of human DNA. Scientists are just beginning to understand its role in cognitive disorders.
Debris from Pluto-sized collisions, not aliens, are streaming through the galaxy. In 2017, scientists discovered an object passing through our Solar System that was unlike anything else we had ever seen. […]
There was a lot of hype and a lot of nonsense, but also some profoundly major advances. Here are the biggest ones you may have missed.
The stars, planets, and many moons are extremely round. Why don’t they take other shapes?
Photosynthesis is powerful but very inefficient. Humans can improve on this biochemical process to help the planet.
Scientists have long puzzled over how Mars, a cold and dry planet, was once warm enough to support liquid water.
Each of our three nearest stars might have an Earth-like planet in orbit around it. Here’s what we’ll learn when we finally observe it.
A biotech startup has received $15 million in funding to genetically recreate woolly mammoths and rewild them in Siberia.
Finding out we’re not alone in the Universe would fundamentally change everything. Here’s how we could do it.
And why you, a non-expert, should absolutely not consider “explaining what you know” to an actual expert in the field.
Carbon dating allows us to know exactly when ice was melted for drinking water in pre-Columbian America.
These ten maps provide a fascinating insight into the impact that soccer (sorry, football) has had worldwide.
Left to their own devices, yeast cells will consume all available resources and poison themselves to death. Is humanity smarter than that?
Multiple lines of evidence — physical, chemical, and biological — must converge for scientists to conclude that alien life has been found.
Impressive but deadly physics underlie catastrophic eruptions.
The simulation gave researchers some of the first concrete data linking climate change to human evolution and speciation.
Innovative thinking has done away with problems that long dogged the electric devices — and both scientists and environmentalists are excited about the possibilities.
Luck doesn’t fall from the sky. It’s about how you position yourself for life’s challenges.
The science fiction dream of a traversable wormhole is no closer to reality, despite a quantum computer’s suggestive simulation.
