In the model they consider, the star is initially part of a binary system at the center of our galaxy. The binary system passes close enough to the supermassive black hole, Sag A*, so that the subgiant is captured in close orbit while its companion escapes. Over time, the orbit of the subgiant decays and the star starts to enter the danger zone of Sag A*. This is where things get interesting.

Because the outer layers of the subgiant are somewhat swollen, they are the first to be captured by the black hole. Essentially, the black hole can rip off the outer layers of the star, leaving a dense helium core. This bare core star continues to orbit ever closer to the black hole until finally being consumed.

A research team from Helmholtz Munich and the Technical University of Munich has developed an advanced delivery system that transports gene-editing tools based on the CRISPR/Cas9 gene-editing system into living cells with significantly greater efficiency than before. Their technology, ENVLPE, uses engineered non-infectious virus-like particles to precisely correct defective genes—demonstrated successfully in living mouse models that are blind due to a mutation.

Personally, I've moved most of my investments into money market funds and plan on buying the dip, just like the multi millionaires. Other than that, I'm getting stocked up on shelf stable foods, and trying to get to know my neighbors a little better.

Scientists at the world’s largest atom smasher have released a blueprint for a much bigger successor that could help solve remaining enigmas of physics.

The plans for the Future Circular Collider — a nearly 91-kilometer (56.5-mile) loop along the French-Swiss border and even below Lake Geneva — published late on Monday put the finishing details on a project roughly a decade in the making at CERN, the European Organization for Nuclear Research.

Scientists have debunked the belief that using tools is unique to mammals and birds, after documenting tropical fish that smash shellfish against rocks to open and eat the meat, in a fascinating new study published in the journal Coral Reefs on 26 March 2025.

Dr. Juliette Tariel-Adam from the School of Natural Sciences at Macquarie University led a project tracking tool use in multiple species of wrasses—a colorful reef fish.

The study logs fish deliberately picking up hard-shelled prey like crabs and mollusks, smashing them against hard surfaces like rocks to access the meal inside.

People often think about archaeology happening deep in jungles or inside ancient pyramids. However, a team of astronomers has shown that they can use stars and the remains they leave behind to conduct a special kind of archaeology in space.

Mining data from NASA's Chandra X-ray Observatory, the team of astronomers studied the relics that one star left behind after it exploded. This "supernova archaeology" uncovered important clues about a star that self-destructed—probably more than a million years ago.

Today, the system called GRO J1655-40 contains a black hole with nearly seven times the mass of the sun and a star with about half as much mass. However, this was not always the case.

Originally GRO J1655-40 had two shining stars. The more massive of the two stars, however, burned through all of its nuclear fuel and then exploded in what astronomers call a supernova. The debris from the destroyed star then rained onto the companion star in orbit around it, as shown in the artist's concept.

Originally GRO J1655-40 had two shining stars. The more massive of the two stars, however, burned through all of its nuclear fuel and then exploded in what astronomers call a supernova. The debris from the destroyed star then rained onto the companion star in orbit around it, as shown in the artist's concept. With its outer layers expelled, including some striking its neighbor, the rest of the exploded star collapsed onto itself and formed the black hole that exists today. The separation between the black hole and its companion would have shrunk over time because of energy being lost from the system, mainly through the production of gravitational waves.

When the separation became small enough, the black hole, with its strong gravitational pull, began pulling matter from its companion, wrenching back some of the material its exploded parent star originally deposited. While most of this material sank into the black hole, a small amount of it fell into a disk that orbits around the black hole. Through the effects of powerful magnetic fields and friction in the disk, material is being sent out into interstellar space in the form of powerful winds.

This is where the X-ray archaeological hunt enters the story. Astronomers used Chandra to observe the GRO J1655-40 system in 2005 when it was particularly bright in X-rays. Chandra detected signatures of individual elements found in the black hole's winds by getting detailed spectra—giving X-ray brightness at different wavelengths—embedded in the X-ray light. Some of these elements are highlighted in the spectrum shown in the inset. The team of astronomers digging through the Chandra data were able to reconstruct key physical characteristics of the star that exploded from the clues imprinted in the X-ray light by comparing the spectra with computer models of stars that explode as supernovae.

They discovered that, based on the amounts of 18 different elements in the wind, the long-gone star destroyed in the supernova was about 25 times the mass of the sun, and was much richer in elements heavier than helium in comparison with the sun.

A paper describing these results titled "Supernova Archaeology with X-Ray Binary Winds: The Case of GRO J1655−40" was published in The Astrophysical Journal.

This analysis paves the way for more supernova archaeology studies using other outbursts of double star systems.

• Lucid plans to start delivering the Gravity SUV to regular customers next month, the company said on Friday.
• Since the start of production in December, it's been making Gravity SUVs for internal use and for a limited number of customers close to the company.
• The Gravity is the EV startup's second model and is key to its future.

Protesters gathered at Tesla dealerships throughout Washington and dozens of other locations across the U.S. on Saturday in a coordinated protest against CEO Elon Musk’s involvement in the federal government. At the Tesla showroom in University Village, hundreds of people were chanting shortly after 10 a.m. Police had blocked vehicle traffic near the showroom, which is in the popular outdoor shopping mall.

A cascade of actions from the Trump administration represents a “grave threat” to health care, social, educational and other critical services in Indian Country, including for Native American communities in the Northwest, tribal leaders say.

In early March, the Trump administration announced the cancellation of leases for at least 12 Indian Health Service facilities and 25 Bureau of Indian Affairs offices, representing nearly 30% of all agency locations, including one each in Toppenish, Washington, and Lapwai, Idaho, as part of an effort to decrease federal office space.

Additionally, IHS employees were included in a buyout offer from the Trump administration, alarming tribal officials and Indigenous community leaders who fear that any employees leaving the understaffed, underfunded agency will force the shutdown of critical health services.
