Artificial intelligence models can now replicate independently new AI systems without any human intervention, according to scientists of the project.
A scientific collaboration between Aizip Inc., the Massachusetts Institute of Technology, and several University of California campuses has made a breakthrough in using larger AI models that can create smaller AI models.
OATH OF OFFICE: DID BIDEN FULFILL HIS PROMISE TO RESTORE THE ECONOMY?
CNS News– A dispute over a McDonald’s food order in Atlanta, Georgia, escalated to a tragic conclusion when Tamanika Woods, a mother of four, was fatally shot. The incident, which took place two days after Christmas, involved 19-year-old T’Niya Evans, who has since been charged with murder and aggravated assault.
This altercation represents a stark example of how quickly conflicts can escalate to violence. According to reports, the argument began over missing food items from an order placed by Evans and her sister. Woods, who was defending a McDonald’s employee and friend, became inadvertently involved.
The dispute tragically ended when Evans allegedly pulled out a gun and shot Woods at point-blank range inside the restaurant. The event was captured on surveillance video, showing Evans confronting and shooting Woods. In a swift response, another patron apprehended Evans, preventing her escape until police arrived.
Novel GHz-class NMR systems are enabling unprecedented life science and materials research in functional structural biology, drug discovery, metabolomics, and cleantech research.
On Jan. 2, a 27-foot sailboat sank off the southern coast of Alameda in stormy weather. Rescue crews saved the man on board, but the ship landed beside a long rock wall jutting from the island.
Eighteen months ago, it was shown that different parts of the interior of the proton must be maximally quantum entangled with each other. This result, achieved with the participation of Prof. Krzysztof Kutak from the Institute of Nuclear Physics of the Polish Academy of Sciences (IFJ PAN) in Cracow and Prof. Martin Hentschinski from the Universidad de las Americas Puebla in Mexico, was a consequence of considerations and observations of collisions of high-energy photons with quarks and gluons in protons and supported the hypothesis presented a few years earlier by professors Dimitri Kharzeev and Eugene Levin.
Now, in a paper published in the journal Physical Review Letters, an international team of physicists has been presented a complementary analysis of entanglement for collisions between photons and protons in which secondary particles (hadrons) are produced by a process called diffractive deep inelastic scattering. The main question was: does entanglement also occur among quarks and gluons in these cases, and if so, is it also maximal?
Putting it in simple terms, physicists speak of entanglement between various quantum objects when the values of some feature of these objects are related. Quantum entanglement is not observed in the classical world, but its essence is easily explained by the toss of two coins. Each coin has two sides, and when it falls, it can take one of two mutually exclusive values (heads or tails) with the same probability.

Studies show that humans have among the most precise and subtle awareness of both musical tonality and ‘beat’, or rhythm.
The evolution of beat perception likely unfolded gradually among primates, reaching its pinnacle in humans.

New discoveries in Tidal Disruption Events enhance our understanding of supermassive black holes and their properties.
A new study by Hebrew University is a significant breakthrough in understanding Tidal Disruption Events (TDEs) involving supermassive black holes. The new simulations, for the first time ever, accurately replicate the entire sequence of a TDE from stellar disruption to the peak luminosity of the resulting flare. This study has unveiled a previously unknown type of shockwave within TDEs, settling a longstanding debate about the energy source of the brightest phases in these events. It confirms that shock dissipation powers the brightest weeks of a TDE flare, opening doors for future studies to utilize TDE observations as a means to measure essential properties of black holes and potentially test Einstein’s predictions in extreme gravitational environments.
The mysteries of supermassive black holes have long captivated astronomers, offering a glimpse into the deepest corners of our universe. Now, a new study led by Dr. Elad Steinberg and Dr. Nicholas C. Stone at the Racah Institute of Physics, The Hebrew University, sheds new light on these enigmatic cosmic entities.
