Explore the discoveries that reveal how the world works, alongside the technologies that extend, reshape, and sometimes challenge what’s possible.

lunar eclipse
We haven't seen a partial eclipse lasting this long since 1440, and won't again until 2669. North America is perfectly positioned for 2021's.
Robot cheetah at MIT
A new control system, demonstrated using MIT’s robotic mini cheetah, enables four-legged robots to jump across uneven terrain in real-time.
Society-changing ideas form through a three-stage process, argues author Michael Bhaskar.
Although most of the Universe's mass is dark matter, which gravitates just as well as normal matter, it still can't make black holes.
Rising Star cave
Fittingly, the skull was found in the Rising Star cave of South Africa, itself located at a site known to UNESCO as the Cradle of Mankind.
inventions
From textiles and transportation to chemicals and microchips, a group of researchers proposes a new way to measure the impact of innovation.
nasa merge black hole
The latest gravitational wave data from LIGO and Virgo finally shows us the truth: there are no "gaps" in the masses of black holes.
how many planets
Based on the atoms that they're made out of, the innermost planet should always be the densest. Here's why Earth beats Mercury, hands down.
Although many dinosaurs never left the ground, they still possessed the basic structural framework for flight.
tooth decay
A mouthwash solution containing ferumoxytol and a dye could treat, prevent, and diagnose tooth decay, according to UPenn researchers.
The history of resuscitation
Ah, ha, ha, ha, stayin' alive, stayin' alive.
elements
There are over 100 known elements in the periodic table. These 8 ways of making them account for every one.
wireless charging
Wireless charging isn't just for phones and laptops. It could also power medical devices like heart implants.
metaverse
If used improperly, the metaverse could be more divisive than social media and an insidious threat to society and even reality itself.
false vacuum
There's a big difference between the notions of 'false vacuum' and 'true vacuum' states. Here's why we don't want to live in the former.
uncertainty
We pretend to be in control, but we have frighteningly little knowledge upon which to base our life’s decisions.
But the upcoming James Webb Space Telescope compels us to add, “so far.” Beginning with its 1990 launch, NASA’s Hubble Space Telescope revolutionized our conception of the Universe. This photo of […]
How the search for alien life is taking place right here in our own Solar System. If you want to understand the origin of life in the Universe, you have three […]
More energy means more potential for discovery, but we’re topped out. If your goal is to discover something completely novel, you have to look in a way that no one else […]
Whatever’s lurking out there, it isn’t all, or even mostly, normal matter. When it comes to the Universe, it’s only natural to wonder what, exactly, it is that makes everything up. […]
