The company has agreed to train its flagship generative AI models primarily on Amazon Web Services (AWS), Amazon’s cloud computing division.

The trial, run by University of Colorado Cancer Center member Al Barqawi, MD, was for a new procedure for treating prostate cancer.

Astronomers have made a groundbreaking discovery of binary star systems, consisting of a white dwarf and a main sequence star, within young star clusters.

This discovery opens up new avenues for understanding stellar evolution and could provide insights into the origins of phenomena such as supernovas and gravitational waves.

The biggest battleground in the robotaxi race may be winning public trust.

Autonomous vehicles are already clocking up millions of miles on public roads, but they face an uphill battle to convince people to climb in to enjoy the ride.

A few weeks ago, I took a tour of San Francisco in one of Waymo’s self-driving cars. As we drove around the city, one thing that struck me was how comfortable people had become with not seeing a driver. Not only were there multiple driverless vehicles on any given street at any given time, but tourists no longer had their mouths agape as one drove by. The technology has become a familiar sight.

Inside the vehicle itself, there were signs of how Waymo is trying to inspire a similar feeling among their passengers. The all-electric car offers a warm welcome to passengers by name and plays music as they climb inside. A screen positioned in front of the rear seats offers those along for the ride the option of seeing a follow-along map of the route, as well as settings for temperature and music. Another screen beside the steering wheel shows images of what’s around the vehicle. As we drive, I can see people sitting inside buses alongside us, dogs crossing the street ahead and children skipping along the sidewalk.

“Quantum physicists are realizing that they can’t ignore the fact that the reference frame Alice is anchored to … might have multiple possible locations at once.”

The quantum nature of reference frames can even affect the perceived order of events.

In a paper this year, the physicist Časlav…

The reference frames from which observers view quantum events can themselves have multiple possible locations at once — an insight with potentially major ramifications.

The rise of quantum computing is more than a technological advancement; it marks a profound shift in the world of cybersecurity, especially when considering the actions of state-sponsored cyber actors. Quantum technology has the power to upend the very foundations of digital security, promising to dismantle current encryption standards, enhance offensive capabilities, and recalibrate the balance of cyber power globally. As leading nations like China, Russia, and others intensify their investments in quantum research, the potential repercussions for cybersecurity and international relations are becoming alarmingly clear.

Imagine a world where encrypted communications, long thought to be secure, could be broken in mere seconds. Today, encryption standards such as RSA or ECC rely on complex mathematical problems that would take traditional computers thousands of years to solve. Quantum computing, however, changes this equation. Using quantum algorithms like Shor’s, a sufficiently powerful quantum computer could factorize these massive numbers, effectively rendering these encryption methods obsolete.

This capability could give state actors the ability to decrypt communications, access sensitive governmental data, and breach secure systems in real time, transforming cyber espionage. Instead of months spent infiltrating networks and monitoring data flow, quantum computing could provide immediate access to critical information, bypassing traditional defenses entirely.

A massive collision of galaxies sparked by one traveling at a scarcely-believable 2 million mph (3.2 million km/h) has been seen in unprecedented detail by one of Earth’s most powerful telescopes.

The dramatic impact was observed in Stephan’s Quintet, a nearby galaxy group made up of five galaxies first sighted almost 150 years ago.

It sparked an immensely powerful shock akin to a “sonic boom from a jet fighter”—the likes of which are among the most striking phenomena in the universe.

Strong interactions between subatomic particles like electrons occur when they are at a specific energy level known as the van Hove singularity. These interactions give rise to unusual properties in quantum materials, such as superconductivity at high temperatures, potentially ushering in exciting technologies of tomorrow.

Research suggests topological materials that allow electrons to flow only on their surface to be promising quantum materials. However, the quantum properties of these materials remain relatively unexplored.

A study co-led by Nanyang Asst Prof Chang Guoqing of NTU’s School of Physical and Mathematical Sciences identified two types of van Hove singularities in the topological materials rhodium monosilicide (RhSi) and cobalt monosilicide (CoSi).

Protons and neutrons–known collectively as nucleons–are both the building blocks of matter, but one of these particles has received a bit more attention in certain types of nuclear physics experiments.

Until now. New results published in Physical Review Letters describe a first-time glimpse of the internal structure of the neutron thanks to the development of a special, 10-years-in-the-making detector installed in Experimental Hall B at the U.S. Department of Energy’s Thomas Jefferson National Accelerator Facility.

“We detected the neutron for the first time in this type of reaction, and it’s quite an important result for the study of nucleons,” said Silvia Niccolai, a research director at the French National Centre for Scientific Research (CNRS).
