They seem like a mundane piece of stationary, just one of hundreds of tools helping you to get through college, but apparently there’s still some advanced research being done in the field of highlighters, resulting in what seems to be the first markers that won’t smear notes written in pen.
Humans have been producing and consuming cheese for a very long time, as the recent discovery of 3,200-year-old cheese in an ancient Egyptian tomb attests. Delicious though this cheese may have been, it was also a potential source of disease.
A team of scientists announced they have harvested hydrogen from water in microgravity—a proof-of-principle test that may one day lead to a way to acquire fuel or other resources during a long-distance, crewed space mission.
Rivers and streams cover much more of the planet than geologists previously estimated, according to a new study published in Science. In total, this new estimate shows that, excluding land with glaciers, Earth is covered by just under 300,000 square miles (773,000 square kilometers) of rivers and streams. That’s more…
Using data collected by NASA’s late-great Cassini space probe, scientists have detected traces of complex organic molecules seeping out from Enceladus’ ice-covered ocean. It’s yet another sign that this intriguing Saturnian moon has what it takes to sustain life.
We tend to associate industrial pollution with the modern era, but human civilizations have been contaminating the planet for thousands of years. By drilling deep into Greenland’s ice sheet, an interdisciplinary team of researchers has chronicled the industrial waste produced by the ancient Greeks and Romans over a…
Good news, future lunar colonists! Scientists have discovered traces of moganite in a lunar meteorite that was discovered 13 years ago in Africa. This mineral requires water to form, so its discovery is being taken as potential confirmation that frozen water exists beneath the Moon’s dusty surface.
NASA announced today that it has completed tests of its Kilopower portable nuclear fission reactor, a device designed to one day power bases on Mars or the moon. The tests met or exceeded expectations on all metrics, which means the device can now go on to more serious flight testing.
A team of physicists has figured out how to bend diamonds, according to a new paper. Okay, we’re talking about nano-scale diamond needles here. But it’s an impressive feat, because while diamonds are known for their hardness, these rocks will break if they are bent even a tiny bit.
Back in 2008, an 80-ton meteor exploded over the Nubian Desert of Sudan, showering the region with hundreds of tiny rocks. New research suggests the diamonds packed inside these meteorites could have only formed within a planetary body the size of Mercury or Mars—a planet that no longer exists.
Finally, scientists have delivered exactly what you’ve been asking for: an edible polymer gel made with caffeine. Finally.
You may make fun, but Ivanka Trump’s very dumb science photo op is actually what most people think when they hear “chemistry.” And it’s not a wrong idea. You mix some chemicals with some other chemicals, and you get molecules—multiple atoms bonded together.
What makes something red, or blue, or green? It’s all in the way light bounces off its surface. Something that primarily reflects light with shorter wavelengths will appear bluer, while something that reflects longer wavelengths will appear redder. By playing around with that principle, scientists have created a…
I’m not gonna lie. Sometimes I see a science paper and think, dang, that’s really cool, I really wish it could do X. Like, maybe a major advancement in flexible, transparent plastic conductors could solve all of my cracked smartphone screen problems. Of course, things are more complex than just that, and a single new…
The United States is dealing with a drug shortage—a legal injection drug shortage, that is. In response, states where capital punishment is still practiced are having to come up with new ways of killing people. Earlier this week, Oklahoma announced that it will start using nitrogen gas for all its executions moving…
H20 is oh-so very weird. It’s on the lighter side of gases, but it’s one of the denser liquids. It’s got an abnormally high freezing and melting point, and it is densest when four degrees above its freezing point, where it changes from a liquid to a solid. A new paper seems to show a source for that weirdness.
Some of the most exciting, mind-blowing physics happens when things get really, really cold—such as atoms clumping beneath the shell of a far-out electron. Imagine a bunch of people huddled under an awning, except the people are atoms, and the awning is... also an atom.
Vibranium’s the lifeblood of the Black Panther universe—the metal that helped propel Wakanda into a hyper-advanced technological society and granted Black Panther his superheroic abilities via a Vibranium-mutated heart-shaped herb. The Wakandan strain, sheared off a meteorite hundreds of years ago, has a number of…
Zoom in close on the center of the picture above, and you can spot something you perhaps never thought you’d be able to see: a single atom. Here is a close-up if, you’re having trouble:
It’s a cruel world out there, and animals will do just about anything to avoid being eaten. In the case of bombardier beetles, these crafty insects are able to escape after being swallowed by toads, which they do by ejecting hot, noxious chemicals that forces the predator to barf. It ain’t pretty, but it works.
