Can quantum particles mimic gravitational waves?
When two black holes collide, space and time shake and energy spreads out like ripples in a pond. These gravitational waves, predicted by Einstein in 1916, were observed for the first time by the Laser Interferometer Gravitational-Wave Observatory (L.....»»
Bringing the power of tabletop precision lasers for quantum science to the chip scale
For experiments that require ultra-precise measurements and control over atoms—think two-photon atomic clocks, cold-atom interferometer sensors and quantum gates—lasers are the technology of choice, the more spectrally pure (emitting a single col.....»»
Physicists uncover strong light-matter interactions in quantum spin liquids
Physicists have long theorized the existence of a unique state of matter known as a quantum spin liquid. In this state, magnetic particles do not settle into an orderly pattern, even at absolute zero temperature. Instead, they remain in a constantly.....»»
Early Earth"s oceans of magma may have accelerated the moon"s departure
The Earth and moon have been locked in a gravitational dance for billions of years. Each day, as the Earth turns, the moon tugs upon the oceans of the world, causing the rise and fall of tides. As a result, the Earth's day gets a little bit longer, a.....»»
Scientists control quantum states in new energy range
An international team of scientists led by Dr. Lukas Bruder, junior research group leader at the Institute of Physics, University of Freiburg, has succeeded in producing and directly controlling hybrid electron-photon quantum states in helium atoms......»»
How influenza A moves: New simulation offers potential to stop spread
A team of bioengineers from the Biohub at the University of California, Berkeley, and the Chan Zuckerberg Initiative has created a simulation to mimic the way the influenza A virus moves through host tissue, presenting a possible new way to stop the.....»»
Physicists introduce approach to control wave patterns via fluid flows
The reliable control of traveling waves emerging from the coupling of oscillations and diffusion in physical, chemical and biological systems is a long-standing challenge within the physics community. Effective approaches to control these waves help.....»»
Eyes on the sun: Naked thallium-205 ion decay reveals history over millions of years
The sun, the essential engine that sustains life on Earth, generates its tremendous energy through the process of nuclear fusion. At the same time, it releases a continuous stream of neutrinos—particles that serve as messengers of its internal dyna.....»»
Tuning skyrmion helicity for racetrack memory and quantum computing applications
Three distinct topological degrees of freedom are used to define all topological spin textures based on out-of-plane and in-plane spin configurations: the topological charge, representing the number of times the magnetization vector m wraps around th.....»»
AI algorithm intensifies gold ion collisions at near-light speed
At Brookhaven National Laboratory's (BNL's) Relativistic Heavy Ion Collider (RHIC), billions of gold ions race through magnets at nearly the speed of light. Thousands of times per second, they collide head-on, breaking into smaller particles that rev.....»»

Graphene stacking discovery could herald new era for quantum applications
Graphene, a single layer of carbon atoms arranged in a two-dimensional honeycomb lattice, is known for its exceptional properties: incredible strength (about 200 times stronger than steel), light weight, flexibility, and excellent conduction of elect.....»»
Milan under stress due to heat waves: Study reveals districts most at risk of cardiovascular emergencies
A new study has analyzed the impact of heat waves on the cardiovascular health of Milan residents. The results show that in 18 highly vulnerable districts, home to 23% of the city's population, the risk of cardiovascular emergencies increases by 22%.....»»
How African countries can build systems to share climate information at the local level
African countries collectively have emitted very little of the greenhouse gases that have caused climate change, but are badly affected by climate-induced floods, droughts and heat waves. To withstand some of the most devastating extreme weather even.....»»
Study uncovers the mafia"s role in Italy"s wildfire crisis
Over the past few years, raging wildfires in Italy have become a common and deadly occurrence. In Southern Italy, intense, record-breaking heat waves and dry scirocco winds create the perfect conditions for wildfires—both natural and coordinated......»»
Pearl Young, the first woman to work in a technical role at NASA, overcame barriers and "raised hell"
Thirteen years before any other woman joined the National Advisory Committee for Aeronautics—or the NACA, NASA's predecessor—in a technical role, a young lab assistant named Pearl Young was making waves in the agency. Her legacy as an outspoken a.....»»
Cosmic rays" vast energy traced to magnetic turbulence
Ultra-high energy cosmic rays, which emerge in extreme astrophysical environments—like the roiling environments near black holes and neutron stars—have far more energy than the energetic particles that emerge from our sun. In fact, the particles.....»»
Google gets an error-corrected quantum bit to be stable for an hour
Using almost the entire chip for a logical qubit provides long-term stability. On Monday, Nature released a paper from Google's quantum computing team that provides a key demonstr.....»»
Not so simple machines: Cracking the code for materials that can learn
