Continents on ancient Earth were created by giant meteor impacts, scientists say

To date, Earth is the only known planet that has continents. It’s unclear exactly how they formed and evolved, but we do know – because the edges of continents thousands of miles apart come together – that long ago Earth’s landmass was concentrated in a single large supercontinent. Since that’s not what the planet looks … Read more

Record-breaking experiment could solve huge challenge in quantum computing

Two atoms blown up to almost comical size and cooled to a fraction above absolute zero have been used to generate a robust and incredibly fast two-qubit quantum gate that could help overcome some of the lingering challenges in quantum computing. Given that a two-qubit gate is the cornerstone of efficient quantum computers, this breakthrough … Read more

Lind Fire fully contained after destroying several houses, seriously injured firefighter recovering | New

LIND, Wash. — After destroying 14 structures on Thursday, the Adams County Sheriff’s Office (SCSO) said the Lind fire is now fully contained. ACSO said the firefighter who was airlifted to Spokane is now home with his family and recovering. Local teams clean up and monitor hot spots. Last update: August 5 at 10:30 a.m. … Read more

Water Can Spontaneously Form Hydrogen Peroxide, and We Finally Understand Why

Since we’ve been plunged into a global pandemic, we’re probably much more aware of being surrounded by micro-droplets of water. In moist air or expelled by coughing, sneezing or talking, these droplets can carry tiny particles with them, from pollution to viruses like the flu. In 2019, the basic chemistry of these environmental water particles … Read more

Scientists reveal first images of atoms ‘swimming’ in liquid

The movement of single atoms through a liquid has been filmed for the first time. Using a sandwich of materials so thin they are effectively two-dimensional, scientists trapped and observed platinum atoms “swimming” along a surface under different pressures. The results will help us better understand how the presence of liquid changes the behavior of … Read more

An AI Just Independently Discovered Alternative Physics

Pick up any physics textbook and you’ll find formula after formula describing how things wobble, fly, swerve, and stop. The formulas describe actions that we can observe, but behind each could be sets of factors that are not immediately obvious. Now, a new AI program developed by researchers at Columbia University has apparently discovered its … Read more

A new set of chemical reactions could finally explain how life began on Earth

Once upon a time, when our planet Earth was very young and very new, there was not a single piece of life on it. Then somewhere, somehow, a quirk of chemistry happened, and the molecular building blocks of our very first single-celled ancestors emerged: the amino acids and nucleic acids that brought together in the … Read more

An ‘impossible’ quasi-crystal was created in the world’s first nuclear bomb test

At 5:29 a.m. on July 16, 1945, in the state of New Mexico, a terrible slice of history was written. The calm of dawn was shattered when the US military detonated a plutonium implosion device known as the Gadget – the world’s first-ever test of a nuclear bomb, known as the test Trinity. This moment … Read more

This strange new phase of matter seems to occupy 2 time dimensions

A new phase of matter has been observed in a quantum computer after physicists pulsed light on its qubits in a pattern inspired by the Fibonacci sequence. If you think it mind-boggling, this strange quirk of quantum mechanics behaves as if it has two time dimensions, instead of just one; a trait that scientists say … Read more

The James Webb Space Telescope may have already found the oldest galaxy ever seen

Just a week after its first images were shown to the world, the James Webb Space Telescope may have found a galaxy that existed 13.5 billion years ago, a scientist who analyzed the data said Wednesday. Known as GLASS-z13, the galaxy dates back 300 million years after the Big Bang, about 100 million years earlier … Read more
