Science and research continuously deliver groundbreaking discoveries, expanding the boundaries of what we know. Each year, the renowned journal Science highlights ten of these achievements in its list of top scientific breakthroughs. For 2024, the journal named the drug lenacapavir — hailed for its potential to reduce HIV/AIDS infections to zero — as the Breakthrough of the Year. In the realm of physics, another major milestone was recognized: the discovery of altermagnetism by researchers at Johannes Gutenberg University Mainz (JGU).

“This is a truly unique tribute to our work, and we are proud and honored to receive this acknowledgment for our research,” said Professor Jairo Sinova of the JGU Institute of Physics. He and his team discovered and demonstrated the phenomenon of altermagnetism.

Until now, physics recognized only two types of magnetism: ferromagnetism and antiferromagnetism. Ferromagnetism, known since ancient Greece, is the force that makes refrigerator magnets stick, where all magnetic moments align in the same direction. Antiferromagnetism, on the other hand, involves magnetic moments aligning in a regular pattern but pointing in opposite directions, canceling each other out externally.

The brain tries to repair damage after a stroke by utilizing its own repair cells, which function like skilled craftsmen. However, their efforts are often obstructed by inflammation, according to new research from the University of Southern Denmark and the University.

A new study conducted by researchers from the Department of Molecular Medicine at SDU highlights one of the most severe consequences of stroke: damage to the brain’s “cables”—the nerve fibers—which results in permanent impairments. Based on unique tissue samples from Denmark’s Brain Bank at SDU, the study could pave the way for new treatments to help the brain repair itself.

Scientists at the PHENIX experiment at RHIC have uncovered compelling evidence that even collisions involving small nuclei with large ones can produce tiny droplets of quark-gluon plasma.

Plasma is one of the four fundamental states of matter, along with solid, liquid, and gas. It is an ionized gas consisting of positive ions and free electrons. It was first described by chemist Irving Langmuir in the 1920s.

Scientists have created over a million simulated cosmic images using the power of supercomputers to anticipate the capabilities of NASA

NASA, the National Aeronautics and Space Administration, is the United States government agency responsible for the nation’s civilian space program and for aeronautics and aerospace research. Established in 1958 by the National Aeronautics and Space Act, NASA has led the U.S. in space exploration efforts, including the Apollo moon-landing missions, the Skylab space station, and the Space Shuttle program.

Google announced that the Chrome Sync feature will be discontinued in early 2025 for Chrome versions older than four years.

When enabled, Chrome Sync keeps users’ bookmarks, passwords, history, open tabs, settings, preferences, and, sometimes, Google Pay payment information. It also automatically signs users into Gmail, YouTube, Search, and other Google services.

The move was announced on the company’s community website over the weekend via a locked post that doesn’t accept replies.

A team of security researchers has disclosed new side-channel vulnerabilities in modern Apple processors that could steal sensitive information from web browsers.

The Georgia Institute of Technology and Ruhr University Bochum researchers, who presented another attack dubbed ‘iLeakage’ in October 2023, presented their new findings in two separate papers, namely FLOP and SLAP, which show distinct flaws and ways to exploit them.

The flaws stem from faulty speculative execution implementation, the underlying cause of notorious attacks like Spectre and Meltdown.
