The scale of chemistry simulations with quantum computing has increased dramatically in just the last few months. In the latest milestone for the field, researchers from Cleveland Clinic, RIKEN, and IBM used a quantum-centric supercomputing (QCSC) framework to calculate the electronic structure of a pair of large protein-ligand complexes, reaching a scale of 12,635 atoms in the largest simulation.
The suspects, ages 17 and 18, were found dead after opening fire at the Islamic Center of San Diego, where a security guard was credited with preventing more deaths
The officer is accused of shooting a man after a pursuing another man to a shared residence; ICE has since investigated whether the officers at the scene lied about being attacked with shovels
German defense tech start-up Helsing and space technology group OHB on Tuesday unveiled a joint venture to develop an AI-powered surveillance and targeting system for use in outer space.
While neutrinos are some of the most abundant particles in the universe, they remain among the least understood. One of the biggest puzzles is their mass: although experiments have shown that neutrinos must have some mass, pinning down exactly how much has proven extraordinarily difficult.
The warrant states that Joseph Magnano should be charged becase he recklessly engaged in conduct that created a grave risk of death to Steven Jones, as well as because the shooting was not legally justified
Using the MeerKAT radio telescope, an international team of astronomers has discovered 15 new millisecond pulsars in 47 Tucanae—one of the closest and best studied globular clusters. The finding is reported in the latest issue of Astronomy & Astrophysics.
I’m a proud Yorta Yorta and Barapa Barapa man, an Indigenous astronomer and a trainee ecologist. When I look at the night sky, I don’t just see stars. Instead, I see an ancient knowledge system that has guided people, culture and Country for tens of thousands of years.
Cosmologists have long struggled to determine whether the universe’s accelerating expansion is being driven by a simple cosmological constant, or whether dark energy’s influence is evolving over time. In a new analysis published in Physical Review D, Samsuzzaman Afroz and Suvodip Mukherjee at the Tata Institute of Fundamental Research, Mumbai, have identified a subtle impact on the inference of the nature of dark energy, due to a tiny mismatch between a fundamental cosmological distance relation and two key datasets used to measure the properties of dark energy.
Asteroid mining seems simple in theory. A spacecraft flies up to a giant rock in space, scoops out some material, and either processes it on site or returns it back to a huge central processing facility. But in practice, it is certainly not that simple, and a new paper from some Spanish researchers, published in the journal Icarus, showcases one of the reasons why—many small asteroids are spinning ridiculously fast.
The middle of the twentieth century was a period of significant scientific advancement, particularly in the realm of physics. Within this rapidly changing landscape, academic disciplines emerged and evolved to keep pace with scientific discoveries. The new subdiscipline of solid-state physics gained prominence in the United States, but it was later subsumed by the broader category of condensed matter physics.
A joint European-Chinese spacecraft blasted off into orbit Tuesday to investigate what happens when extreme winds and giant explosions of plasma shot out from the sun slam into Earth’s magnetic shield.
Before Smile can begin studying how Earth responds to the streams of particles and bursts of radiation from the sun, the spacecraft had to complete an extraordinary journey here on Earth.
In December 2023, scientists looking at Mars data stumbled across something completely unexpected—observations of an atmospheric effect never before seen in the Red Planet’s atmosphere. Using instruments aboard NASA’s MAVEN (Mars Atmosphere and Volatile Evolution) mission, scientists identified a phenomenon known to occur in Earth’s magnetosphere, where charged particles are squeezed like toothpaste coming out of a tube along magnetic structures called flux tubes.
The rapid growth of large language models is placing increasing demands on data centers, where large volumes of data must be transferred efficiently between servers. Optical interconnects are essential for enabling this communication, but as data rates continue to rise, these systems must deliver higher bandwidth while maintaining low latency and energy efficiency. However, integrating electronic and photonic components remains challenging, as conventional approaches often introduce signal loss, limit interconnect density, and restrict scalability.
