UNLV researchers and colleagues may have identified the first known planet to orbit three stars.

Unlike our solar system, which consists of a solitary star, it is believed that half of all star systems, like GW Ori where astronomers observed the novel phenomenon, consist of two or more stars that are gravitationally bound to each other.

But no planet orbiting three stars—a circumptriple orbit—has ever been discovered. Perhaps until now.

Researchers have discovered a complex landscape of electronic states that can co-exist on a kagome lattice, resembling those in high-temperature superconductors, a team of Boston College physicists reports in an advance electronic publication of the journal Nature.

The focus of the study was a bulk single crystal of a topological kagome metal, known as CsV₃Sb₅—a metal that becomes superconducting below 2.5 degrees Kelvin, or minus 455 degrees Fahrenheit. The exotic material is built from atomic planes composed of Vanadium atoms arranged on a so-called kagome lattice—described as a pattern of interlaced triangles and hexagons—stacked on top of one another, with Cesium and Antimony spacer layers between the kagome planes.

The material offers a window into how the physical properties of quantum solids—such as light transmission, electrical conduction, or response to a magnetic field —relate to the underlying geometry of the atomic lattice structure. Because its geometry causes destructive interference and “frustrates” the kinetic motion of traversing electrons, kagome lattice materials are prized for offering the unique and fertile ground for the study of quantum electronic states described as frustrated, correlated and topological.

“We are going to get so wrecked,” he added.

The kind of value systems that humans have used to structure societies over history — regardless of their success in bringing about meaningful change — may soon no longer be relevant.

“Idk, I think the broader point is just that machines might end up having a lot more flexibility on how they organize themselves than we do,” Hodak pondered in a follow-up tweet. “It takes generations to upgrade cognitive technology in human societies.”

When Dr. Robert Murphy first started researching biochemistry and drug development in the late 1970s, creating a pharmaceutical compound that was effective and safe to market followed a strict experimental pipeline that was beginning to be enhanced by large-scale data collection and analysis on a computer.

Now head of the Murphy Lab for computational biology at Carnegie Mellon University (CMU), Murphy has watched over the years as data collection and artificial intelligence have revolutionized this process, making the drug creation pipeline faster, more efficient, and more effective.

Recently, that’s been thanks to the application of machine learning—computer systems that learn and adapt by using algorithms and statistical models to analyze patterns in datasets—to the drug development process. This has been notably key to reducing the presence of side effects, Murphy says.

The timeframe for reinfection is fundamental to numerous aspects of public health decision making. As the COVID-19 pandemic continues, reinfection is likely to become increasingly common. Maintaining public health measures that curb transmission—including among individuals who were previously infected with SARS-CoV-2—coupled with persistent efforts to accelerate vaccination worldwide is critical to the prevention of COVID-19 morbidity and mortality.

Supersonic and hypersonic aircraft are slowly but surely coming back to the forefront of aviation. NASA is in the last development stages of its supersonic research aircraft, X-59, and Stratolaunch is getting ready to operate its first hypersonic test vehicle, the Talon-A.

More than 6,000 Coinbase users had funds stolen from their accounts after hackers used a vulnerability in Coinbase’s SMS-based two-factor authentication system to breach accounts.

The intrusions took place earlier this year, between March and May, the exchange said in a data breach notification letter it has filed with US state attorney general offices.

“The third party took advantage of a flaw in Coinbase’s SMS Account Recovery process in order to receive an SMS two-factor authentication token and gain access to your account,” Coinbase said.

BERLIN (AP) — A joint European-Japanese spacecraft got its first glimpse of Mercury as it swung by the solar system’s innermost planet while on a mission to deliver two probes into orbit in 2025.

The BepiColombo mission made the first of six flybys of Mercury at 11:34 p.m. GMT (7:34 p.m. EST) Friday, using the planet’s gravity to slow the spacecraft down.

After swooping past Mercury at altitudes of under 200 kilometers (125 miles), the spacecraft took a low resolution black-and-white photo with one of its monitoring cameras before zipping off again.
