Researchers at the DarkSide collaboration have unveiled results from a seven-year experiment that tested whether dark matter particles could exist as composites of smaller, elementary particles. While the search turned up ...

When water drains from a bathtub, a whirlpool often forms above the drain, and its narrow core can start to wobble and twist. For almost 150 years, physicists have predicted that these wobbles can become turbulent, passing ...

In their earliest years of development, computers used mechanical gears and levers to store information. Today, researchers are exploring whether a material itself can hold onto information, storing memory in how it bends ...

Researchers in China have extended the lifetime of entanglement in a room-temperature, solid-state system by up to a factor of 240. Led by Shuo Ren and Rui-Jian Liang at the University of Science and Technology of China in ...

Nitrogen is a key ingredient in the biomolecules that form the building blocks of life. Yet as an unbonded gas, it is far more likely to drift into space than to lock itself into solid compounds, making it difficult for astronomers ...

For decades, physicists have worked to prove the strange predictions of quantum mechanics with real experiments. As quantum computers have grown more powerful, researchers have devised increasingly sophisticated ways to test ...

Physicists at the BESIII Collaboration have breathed new life into a decades-old test of one of the Standard Model's most important ideas, using a technique that had gone almost untouched by experimenters for 35 years.

For the first time since its dramatic dimming in 2020, a team of astronomers has observed the inner atmosphere of Betelgeuse using the Atacama Large Millimeter Array (ALMA). Led by Bill Dent at the University of Manchester, ...

Gravitational waves are ripples in spacetime created when pairs of black holes spiral into each other and eventually merge. But if this ripple has been warped by another massive object on its way to Earth, a new analysis ...

The weak equivalence principle (WEP) is central to Einstein's general relativity. It posits that gravity must accelerate everything equally, regardless of what it is made from. For the first time, a team led by Ming-Sheng ...

For nearly 80 years, physicists have relied on a thought experiment created by Richard Feynman to predict how quantum particles behave. For the first time, researchers in China have tested this trick directly in the lab.

Welding plastic is a critically important part of everyday engineering—especially for preventing leaks in underground water and gas pipes. For decades, engineers have understood that a properly welded joint in polyethylene ...

Dark matter is known to make up roughly 85% of all mass in the universe, as evidenced by the way galaxies spin and how galaxy clusters are held together under gravity. Yet despite decades of searching, physicists have never ...

For decades, physicists have used a technique called Mössbauer spectroscopy to peer inside solid materials, revealing fine details of their surroundings by studying how their atomic nuclei absorb and re-emit gamma rays.

During a coronal mass ejection (CME), the sun hurls billions of tons of magnetized plasma into space. These eruptions are among the most powerful events in the solar system, and when they are aimed toward Earth, they can ...
