Physicists take a major step toward making a nuclear clock
By tweaking the energy of a thorium nucleus with a laser, scientists demonstrated a key step to building clocks based on the physics of atomic nuclei.
- Particle Physics
Forests might serve as enormous neutrino detectors
Trees could act as antennas that pick up radio waves of ultra-high energy neutrinos interactions, one physicist proposes.
- Physics
‘Countdown’ takes stock of the U.S. nuclear weapons stockpile
Physicists grapple with their role as stewards of the United States’ aging nuclear weapons in the new book by Sarah Scoles.
- Physics
Here’s how scientists reached nuclear fusion ‘ignition’ for the first time
The first fusion experiment to produce an energy excess required meticulous planning and also revealed a long-predicted heating phenomenon.
- Artificial Intelligence
AI chatbots can be tricked into misbehaving. Can scientists stop it?
To develop better safeguards, computer scientists are studying how people have manipulated generative AI chatbots into answering harmful questions.
- Physics
A pivotal quantum theory holds up even in extreme electric fields
Quantum electrodynamics, which describes how charged particles and light interact, works in the strong fields around highly ionized uranium atoms.
- Physics
A predicted quasicrystal is based on the ‘einstein’ tile known as the hat
The einstein tile can cover an infinite plane only with a nonrepeating pattern. A material based on it has features of both crystals and quasicrystals.
- Physics
What happens when lawn sprinklers suck in water? Physicists answer that quirky question
Experiments with a floating sprinkler and laser-illuminated microparticles revealed the surprisingly complex physics behind a simple question.
- Materials Science
Artificial intelligence helped scientists create a new type of battery
It took just 80 hours, rather than decades, to identify a potential new solid electrolyte using a combination of supercomputing and AI.
- Physics
Here’s the science behind the burbling sound of water being poured
The height of the pour and the thickness of the stream help determine the loudness of the falling water.
- Physics
Invisible comet tails of mucus slow sinking flakes of ‘marine snow’
New measurements reveal the gunk that surrounds the particles, an important factor in understanding how the ocean sequesters carbon.
- Quantum Physics
A maverick physicist is building a case for scrapping quantum gravity
To merge quantum physics and general relativity, physicists aim to quantize gravity. But what if gravity isn’t quantum at all?
