NASA’s SOFIA mission is upgraded and back in action, and the Cigar Galaxy makes a perfect target. In theory, cold, neutral gas is the key to stars and galaxies. A visualization […]

The concept of burnout is nothing new. But there are ways to prevent burnout and promote greater engagement with work.
Despite the Sun’s high core temperatures, particles can’t quite overcome their mutual electric repulsion. Good thing for quantum physics!
For the first time, it was discovered that nonphotosynthetic bacteria have a circadian clock.
Two ICU physicians offer a new approach to stopping it.
And, at some point, did the Milky Way lose ours? There are some 400 billion objects flying through the Milky Way galaxy with enough mass that — if they were all made of […]
Should we take people’s drunken behavior as evidence of their true character?
It’s not a gambit. It’s not fraud. It’s not driven by opinion, prejudice, or bias. It’s not unchallengeable. And it’s more than facts alone.
Battery-powered urban aircraft are well within the bounds of technological reality.
If the multiverse is real, where does all the energy for it come from? One of the biggest scientific puzzles, even given our knowledge of the Big Bang, is to understand […]
How two seemingly distinct exoplanet systems turned out to be related. Practically every star in the Milky Way has a similar origin story. At some point in the past, a molecular […]
One million year old mammoth DNA more than doubles the previous record and suggests that even older genomes could be found.
We cannot deduce laws about a higher level of complexity by starting with a lower level of complexity. Here, reductionism meets a brick wall.
Iceland consistently ranks as the most gender-equal nation. It is also the nation where men and women are most likely to pursue sex-typical jobs.
Although human beings arrived on Earth just ~300,000 years ago, we’ve transformed the entire planet completely. Here’s how we did it.
And either way, is energy or information conserved? When two things in the Universe that “always” occur meet one another, how do you know which one will win? Gravitational waves, […]
In Sun-like stars, hydrogen gets fused into helium. In the Big Bang, hydrogen fusion also makes helium. But they aren’t close to the same.
MIT neuroscientists have identified a population of neurons in the human brain that respond to singing but not other types of music.
The newly discovered galaxies are 62 times bigger than the Milky Way.
As the world warms, trees in forests such as those in Minnesota will no longer be adapted to their local climates. That’s where assisted migration comes in.
What was once an art form has been drained of color and personality by ruthless algorithms. Can we make chess human again?
How can you “touch the Sun” if you’ve always been inside the solar corona, yet will never reach the Sun’s photosphere?
New mathematics have shown that lines of energy can be used to describe the universe.
You can only create or destroy matter by creating or destroying equal amounts of antimatter. So how did we become a matter-rich Universe?
It could evolve, strengthen, decay, or not be alone. Our known Universe contains matter, radiation, and dark energy. While matter (both normal and dark) and radiation become less dense as […]
Speculation about the existence of aliens goes all the way back at least to the Greek philosophers. Their arguments will sound familiar.
If they have mass, then why don’t we see any slow-moving ones? For decades, the neutrino was among the most puzzling and elusive of cosmic particles. It took more than […]
Are dark matter and dark energy both two sides of the same coin? When it comes to the Universe, what you can easily see isn’t always reflective of all there is. […]
The combination of charge conjugation, parity, and time-reversal symmetry is known as CPT. And it must never be broken. Ever.
