The first observational evidence showing the Universe is expanding is 100 years old now: in 2023. Here's the story of its 100th anniversary.
How fast is the Universe expanding? Two major methods disagree. New JWST data, just released, strengthens this Hubble tension even further.
Smarter building materials can control indoor temperatures without external power.
Whether you call it 10 quintillion, 10 million trillion, or 10 billion billion, it's a 1 followed by 19 zeroes.
The technology could yield "made-to-order resistance genes" to protect crops against pathogens and pests.
A 1.5-million-year-old hominin bone shows signs that the victim was eaten by lions — and humans.
Some constants, like the speed of light, exist with no underlying explanation. How many "fundamental constants" does our Universe require?
The use of the letter x as an unknown is a relatively modern convention.
Nature may not allow us full access to the weirdness of quantum mechanics.
Ethicist and doctor Simon Whitney argues that society's overly cautious approach to medical research is blocking breakthroughs.
In many ways, it was worse than Chernobyl.
Two fundamentally different ways of measuring the expanding Universe disagree. What's the root cause of this Hubble tension?
Today, many Maya sites are polluted with toxic levels of mercury. The contamination likely originated from cinnabar paints and art.
The Schumann resonances are the background hum of the entire planet. But they don't affect humans in any way.
Don’t argue with science. Just do it.
As Marcel Proust said, “The real voyage of discovery... consists not in seeking new landscapes, but in having new eyes.”
LK-99, almost certainly, isn't a room-temperature superconductor. The underlying physics of the phenomenon helps us understand why.
The visible Universe extends 46.1 billion light-years from us, while we've probed scales down to as small as ~10^-19 meters.
It could cut the time needed to reach Mars in half.
How scientists are hearing the gravitational background "hum" of the Universe for the very first time.
Someday, scientists could use stem cells to guide the development of synthetic organs for patients awaiting transplants.
Einstein's laws of gravity have been challenged many times, but have always emerged victorious. Could wide binary stars change all that?
A company in England has made a test that picks out the compounds from breath that reveal if people have liver disease.
There may be unknown particles lurking inside the quantum foam.
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.
Metaphors like the Great Chain of Being can lead people to misunderstand evolution and humanity’s place in the web of life.
Decades of Alzheimer's research might have missed a cellular culprit hiding in plain sight.
Is LK-99 truly a room temperature superconductor? These 4 tests, none of which have yet been passed, will separate fact from fiction.
The patron saint of calling BS, Harry Frankfurt, died watching his philosophy become more urgent than ever.
Pain relievers like acetaminophen and ibuprofen are made with chemicals derived from oil. Scientists have shown how to make them from trees.
