A study by the University of Bonn: Observations fit poorly with the Standard Model of Cosmology.

The Standard Model of Cosmology describes how the universe came into being according to the view of most physicists. Researchers at the University of Bonn have now studied the evolution of galaxies within this model, finding considerable discrepancies with actual observations. The University of St. Andrews in Scotland and Charles University in the Czech Republic were also involved in the study. The results have now been published in the Astrophysical Journal.

Most galaxies visible from Earth resemble a flat disk with a thickened center. They are therefore similar to the sports equipment of a discus thrower. According to the Standard Model of Cosmology, however, such disks should form rather rarely. This is because in the model, every galaxy is surrounded by a halo of dark matter. This halo is invisible, but exerts a strong gravitational pull on nearby galaxies due to its mass. “That’s why we keep seeing galaxies merging with each other in the model universe,” explains Prof. Dr. Pavel Kroupa of the Helmholtz Institute for Radiation and Nuclear Physics at the University of Bonn.

SAN FRANCISCO/SHANGHAI, Feb 8 (Reuters) — SoftBank Group Corp (9984.T) has shelved its blockbuster sale of Arm Ltd to U.S. chipmaker Nvidia Corp (NVDA.O) valued at up to $80 billion citing regulatory hurdles and will instead seek to list the company.

Britain’s Arm, which named a new CEO on Tuesday, said it would go public before March 2023 and SoftBank CEO Masayoshi Son indicated that would be in the United States, most likely the Nasdaq.

SoftBank acquired Arm, whose technology powers Apple’s iPhone and nearly all other smartphones, in 2016 for $32 billion.

Bright indoor lighting during daytime.

According to a new study published in Diabetologia, Insulin-resistant volunteers’ postprandial substrate processing, energy expenditure, and thermoregulation are all affected by the indoor light environment in a time-dependent manner. Further Optimization of indoor lighting to a brighter during daytime hours and dimmer in the evening may provide cardiometabolic benefits.

Artificial light is available 24 hours a day in today’s civilization, and most individuals are exposed to electrical light and light-emitting screens during the dark part of the natural light/dark cycle. Suboptimal lighting has been linked to negative metabolic impacts, and changing indoor lighting to more closely mirror the natural light/dark cycle has the potential to improve metabolic health.

But the benefits of fusion reaction are immense. Apart from generating much more energy, fusion produces no carbon emissions, the raw materials are in sufficient supply, produces much less radioactive waste compared to fission, and is considered much safer.

Over the years, scientists have been able to draw up the plan for a fusion nuclear reactor. It is called ITER (International Thermonuclear Experimental Reactor) and is being built in southern France with the collaboration of 35 countries, including India which is one of the seven partners, alongside the European Union, the United States, Russia, Japan, South Korea and China.

Researchers from Chalmers University of Technology have produced a structural battery that performs ten times better than all previous versions. It contains carbon fiber that serves simultaneously as an electrode, conductor, and load-bearing material. Their latest research breakthrough paves the way for essentially ’massless’ energy storage in vehicles and other technology.

The batteries in today’s electric cars constitute a large part of the vehicles’ weight, without fulfilling any load-bearing function. A structural battery, on the other hand, is one that works as both a power source and as part of the structure – for example, in a car body. This is termed ‘massless’ energy storage, because in essence the battery’s weight vanishes when it becomes part of the load-bearing structure. Calculations show that this type of multifunctional battery could greatly reduce the weight of an electric vehicle.

Similarly, entanglement seems to be fundamental to the existence of space-time. This was the conclusion reached by a pair of postdocs in 2006: Shinsei Ryu (now at the University of Illinois, Urbana-Champaign) and Tadashi Takayanagi (now at Kyoto University), who shared the 2015 New Horizons in Physics prize for this work. “The idea was that the way that [the geometry of] space-time is encoded has a lot to do with how the different parts of this memory chip are entangled with each other,” Van Raamsdonk explained.

Inspired by their work, as well as by a subsequent paper of Maldacena’s, in 2010 Van Raamsdonk proposed a thought experiment to demonstrate the critical role of entanglement in the formation of space-time, pondering what would happen if one cut the memory chip in two and then removed the entanglement between qubits in opposite halves. He found that space-time begins to tear itself apart, in much the same way that stretching a wad of gum by both ends yields a pinched-looking point in the center as the two halves move farther apart. Continuing to split that memory chip into smaller and smaller pieces unravels space-time until only tiny individual fragments remain that have no connection to one another. “If you take away the entanglement, your space-time just falls apart,” said Van Raamsdonk. Similarly, “if you wanted to build up a space-time, you’d want to start entangling [qubits] together in particular ways.”

Combine those insights with Swingle’s work connecting the entangled structure of space-time and the holographic principle to tensor networks, and another crucial piece of the puzzle snaps into place. Curved space-times emerge quite naturally from entanglement in tensor networks via holography. “Space-time is a geometrical representation of this quantum information,” said Van Raamsdonk.

Long before Alzheimer’s disease is diagnosed, once-trusty proteins start to knot together in the brain in a process that may be hastened by poor sleep.

Now, scientists have uncovered a possible mechanism linking disruptions in circadian rhythms and the build-up of proteins associated with Alzheimer’s disease, by studying the rhythmic operation of immune cells and finding the molecular ‘timers’ that control them.

Circadian rhythms are the daily rhythms of bodily functions which are tied to our natural body clock, respond to light exposure, and govern our sleep-wake cycles.
