Here’s how often it goes off.

Just like you, our planet has a ticker that keeps time: Earth’s geological “heartbeat” goes off on a regular schedule, albeit with millions of years in between, says a new study in Geoscience Frontiers.

When scientists from New York University and the Carnegie Institution of Science in Washington D.C. analyzed 260 million years of geological feedback, they found “global geologic events are generally correlated,” and seemingly come in pulses every 27.5 million years.

Elon Musk—via Starlink, a division of SpaceX—is in talks with “several” airlines to provide in-flight WiFi for passengers. His plan is to use Starlink’s ever-growing megaconstellation of satellites to equip customers with better WiFi while they fly the friendly skies.

Jonathan Hofeller, SpaceX’s vice president of Starlink and commercial sales, gave out details on the ambitious plan during a panel at the Connected Aviation Intelligence Summit on Wednesday.

With the help of robotics specialists, we can separate the truth from the hype.

Elon Musk has announced his plans for a new Tesla humanoid robot that will excel at “mundane tasks,” but he’s making some common robotics mistakes with his grand plans.

An eruption before a stellar explosion was the first early warning sign for a standard type of supernova.

Researchers explored the evolution of metal-binding proteins across billions of years.

Addressing one of the most profoundly unanswered questions in biology, a Rutgers-led team has discovered the structures of proteins that may be responsible for the origins of life in the primordial soup of ancient Earth.

The study appears in the journal Science Advances.

We now know of almost 5,000 planets outside the Solar System. If you were to picture what it would be like on one of these distant worlds, or exoplanets, your mental image would probably include a parent star—or more than one, especially if you’re a Star Wars fan.

But scientists have recently discovered that more planets than we thought are floating through space all by themselves—unlit by a friendly stellar companion. These are icy “free-floating planets,” or FFPs. But how did they end up all on their own and what can they tell us about how such planets form?

Finding more and more exoplanets to study has, as we might have expected, widened our understanding of what a planet is. In particular, the line between planets and “brown dwarfs”— cool stars that can’t fuse hydrogen like other stars —has become increasingly blurred. What dictates whether an object is a planet or a brown dwarf has long been the subject of debate—is it a question of mass? Do objects cease to be planets if they are undergoing nuclear fusion? Or is the way in which the object was formed most important?

A tsunami advisory has been issued for Hawaii and parts of the U.S. Pacific coast after an undersea volcano erupted in spectacular fashion near Tonga on Saturday.

California, Oregon, Washington, Alaska and the Canadian province of British Columbia could all be affected, the National Tsunami Warning Center said in a bulletin.

Residents living near beaches, harbors, marinas and other coastal areas should move away from the shore and make their way inland or uphill, the bulletin added.

For quantum computers to surpass their classical counterparts in speed and capacity, their qubits—which are superconducting circuits that can exist in an infinite combination of binary states—need to be on the same wavelength. Achieving this, however, has come at the cost of size. Whereas the transistors used in classical computers have been shrunk down to nanometer scales, superconducting qubits these days are still measured in millimeters—one millimeter is one million nanometers.

Combine qubits together into larger and larger circuit chips, and you end up with, relatively speaking, a big physical footprint, which means quantum computers take up a lot of physical space. These are not yet devices we can carry in our backpacks or wear on our wrists.

To shrink qubits down while maintaining their performance, the field needs a new way to build the capacitors that store the energy that “powers” the qubits. In collaboration with Raytheon BBN Technologies, Wang Fong-Jen Professor James Hone’s lab at Columbia Engineering recently demonstrated a superconducting qubit capacitor built with 2D materials that’s a fraction of previous sizes.
