But he added that the US does need more Chinese students, too — just not in STEM. AdvertisementHe also cited security concerns about letting Chinese students access sensitive technology. But even now, Chinese students say that they have been facing extra scrutiny while entering the US. The Washington Post, citing online discussion forums, reported in March that Chinese students were questioned for hours at US border controls, or had their visas canceled without valid reasons. In April, the Senate passed a bill that, if signed into law by President Joe Biden, will force Chinese tech company Bytedance to sell video site TikTok.

Richard Hatch was searching the card catalog of the Sterling Memorial Library at Yale, hunting for intriguing titles under the subject heading “Magic.” It was 1979, and Hatch was a young graduate student in physics, but he’d long nurtured an amateur’s passion for the conjuring arts and, on this day at least, he preferred to read about sleight of hand than quantum mechanics. His rummaging stopped when he spotted a title called “Die Juden in der Zauberkunst.” Hatch had spent four years of his youth in Germany so he translated it instantly: “Jews in Magic.” The card said the book was written by someone named Guenther Dammann and published in Berlin in 1933. A book about Jews in magic, from Germany, in the very year that the Nazis assumed power and started burning “un-German” books in bonfires across the country. It seemed obvious. This was an antisemitic tract, identifying Jews to make it easier for the government to persecute them and the public to shun them.

CNN —Jupiter’s iconic Great Red Spot is a massive storm that has swirled within the atmosphere of the largest planet in the solar system for years. The Great Red Spot is a massive vortex within Jupiter’s atmosphere that is about 10,159 miles (16,350 kilometers) wide, which is similar to Earth’s diameter, according to NASA. Vincenzo Pinto/AFP/Getty ImagesWhile the first two scenarios resulted in cyclones, they differed in shape and other characteristics witnessed in the Great Red Spot. But the researchers believe that the persistent atmospheric storm cell, which resulted from intense wind instability, produced the Great Red Spot. Previous research, published in March 2018, has shown that the Great Red Spot is growing taller as it shrinks in size overall.

Piping Up at the Gates of Dawn
  + stars: | 2024-06-22 | by ( Dennis Overbye | ) www.nytimes.com   time to read: +1 min
Since the James Webb Space Telescope began operating two years ago, astronomers have been using it to leapfrog one another millions of years into the past, back toward the moment they call cosmic dawn, when the first stars and galaxies were formed. Last month, an international team doing research as the JWST Advanced Deep Extragalactic Survey, or JADES, said it had identified the earliest, most distant galaxy yet found — a banana-shaped blob of color measuring 1,600 light-years across. It was already shining with intense starlight when the universe was in its relative infancy, at only 290 million years old, the astronomers said. The new galaxy, known as JADES-GS-z14-0, is one of a string of Webb discoveries, including early galaxies and black holes, that challenge conventional models of how the first stars and galaxies formed. “This discovery proves that luminous galaxies were already in place 300 million years after the Big Bang and are more common than what was expected,” the researchers wrote in a paper posted to an online physics archive.

How primordial black holes could explain dark matter
  + stars: | 2024-06-17 | by ( Jacopo Prisco | ) edition.cnn.com   time to read: +10 min
The late physicist Stephen Hawking hypothesized that dark matter could be hiding in black holes formed during the big bang. “We were making use of Stephen Hawking’s famous calculations about black holes, especially his important result about the radiation that black holes emit,” Kaiser said. This is not to say dark matter is not a particle, or that it’s for sure black holes. “The next generation of gravitational detectors could catch a glimpse of the small-mass black holes — an exotic state of matter that was an unexpected byproduct of the more mundane black holes that could explain dark matter today.”Many forms of dark matterWhat does this mean for the ongoing experiments that are trying to detect dark matter, such as the LZ Dark Matter Experiment in South Dakota? And those indeed might pick up some of the stray signals from the very violent formation process of primordial black holes.”There’s also the possibility that primordial black holes are just a fraction of the dark matter, Alonso-Monsalve added.

CNN —The best athletes break all sorts of new ground in pursuit of greatness, looking for that extra tiny percent that can propel them above their rivals. For Bryson DeChambeau that extra kick might be found in the most surprising of places – Epsom salt. After taking control of the US Open with a captivating third-round performance on Saturday, the American elaborated on his habit of salting his golf balls before playing, just another aspect of his analytical approach to the game which has earned him the nickname of “The Scientist.”“I put my golf balls in Epsom salt,” he told reporters. “Essentially we float golf balls in a solution to make sure the golf ball is not out of balance.”His manager, Connor, was in charge of salting the golf balls, DeChambeau explained, to find out “how much out of balance” they were. “There’s always going to be an error, especially when it’s a sphere and there’s dimples on the edges,” he added.

Now, a new study that looked at 5 million stars in the Milky Way galaxy suggests that seven candidates could potentially be hosting Dyson spheres — a finding that’s attracting scrutiny and alternate theories. If Dyson spheres really exist, what could they be used for? “Freeman Dyson said that we should dismantle Jupiter — the whole planet (for the raw materials).”That supercolossal scale probably means that Dyson spheres, if they exist at all, are very rare. “However, contamination by circumstellar debris disks, which mimic Dyson Sphere infrared signatures, remains a concern,” he added in an email. However, he added, the radiation fingerprint of the seven Dyson sphere candidates might be explained by natural phenomena as well.

Samsung unveils plan to speed up delivery of AI chips
  + stars: | 2024-06-12 | by ( ) edition.cnn.com   time to read: +2 min
Samsung expects global chip industry revenue to grow to $778 billion by 2028, boosted by AI chips, Choi said. Samsung is one of the few companies that sells memory chips, offers foundry services and designs chips under the same roof. GAA is seen as important to keep making more powerful chips for AI as chips become finer to the point of pushing the boundaries of physics. Although competitors such as global foundry No 1 TSMC are also working on chips using GAA, Samsung started applying GAA earlier, and said it plans to mass produce its second-generation 3-nanometer chips using GAA in the second half of this year. Samsung also announced its latest 2-nanometer chipmaking process for high-performance computing chips, which places power rails on the backside of the wafer to improve power delivery.

While a supernova is the explosive death of a massive star, a nova refers to the sudden, brief explosion from a collapsed star known as a white dwarf. The dwarf star remains intact, releasing material in a repetitive cycle that can occur for thousands of years. “It’s incredibly exciting to have this front-row seat.”T Coronae Borealis, otherwise known as the “Blaze Star,” is a binary system in the Corona Borealis that includes a dead white dwarf star and an aging red giant star. The red giant becomes increasingly unstable over time as it heats up, casting off its outer layers that land as matter on the white dwarf star. Cooke recalled that the last nova he witnessed — Nova Cygni in 1975 — had a similar brightness to what is expected from T Coronae Borealis.

Payden's assets have grown with the firm: As majority owner, she boasts an estimated net worth of roughly $700 million and is a "newcomer" on Forbes' recently published 2024 list of America's Richest Self-Made Women. "I was hired at a 25% discount because I didn't know the difference between a bond and stock," Payden told the Los Angeles Times in 1999. Within a couple years, she moved to Los Angeles to join Scudder, Stevens & Clark, a prestigious money management firm. She failed at least one of those attempts because she "didn't play golf" at an annual meeting on a men-only course, Payden told students at Notre Dame in 2011. Since then, she's built her firm into one of the largest private money management firms in the U.S.

Born in Mexico City in 1962, she has two children and one grandchild. In 2018, she became the head of government of Mexico City, the first woman elected to this position. Current and former US officials have frequently described the relationship between President Joe Biden and Mexico’s President Andrés Manuel López Obrador as friendly and professional — and anticipate a productive relationship with Mexico’s next president. But Mexico’s election also comes at a critical time for the Biden administration. One of the considerations in rolling out a new border executive action was doing so after Mexico’s election.

The order in which the planets will align on Sunday is Jupiter, Mercury, Uranus, Mars, Neptune and Saturn, and they will be accompanied by a crescent moon. The alignment will be visible to sky-watchers everywhere, but the ideal date to see the planets with the closest alignment might differ depending on where you are in the world. Planetary alignments: What to knowIt’s important to note that this alignment is not happening in space, but just in the sky as seen from our planet. This kind of planetary alignment is in fact not rare at all. “Jupiter will be the easiest to spot, because it’ll be the brightest thing in the sky after the moon,” Pattle said.

Opinion | Step Aside, DNA. RNA Has Arrived.

Then, in the early 1950s, biology began to nudge physics out of the scientific spotlight — and when I say “biology,” what I really mean is DNA. The momentous discovery of the DNA double helix in 1953 more or less ushered in a new era in science that culminated in the Human Genome Project, completed in 2003, which decoded all of our DNA into a biological blueprint of humankind. You may remember learning about RNA (ribonucleic acid) back in your high school biology class as the messenger that carries information stored in DNA to instruct the formation of proteins. Such messenger RNA, mRNA for short, recently entered the mainstream conversation thanks to the role they played in the Covid-19 vaccines. But RNA is much more than a messenger, as critical as that function may be.

The time may have finally come for small-cap stocks to have their moment in the sun, according to Jefferies. "We have seen some improvement in absolute and relative performance and think we could have hit an inflection point," wrote Jefferies strategist Steven DeSanctis. Still, he said there's one caveat: small-cap earnings look weak on an absolute basis. "As the year rolls along, small-cap earnings are set to broaden, accelerate, and play a game of catch-up with large." Jefferies' price target of $140 is nearly 32% higher than where shares of ArcBest closed on Thursday afternoon.

In contrast to previous research that assumed the sun’s magnetic field originates from deep within the celestial body, they suspect the the source is much closer to the surface. This view of the sun's magnetic field was generated by NASA's Solar Dynamics Observatory. NASA/GSFC/Solar Dynamics ObservaModeling the sun’s magnetic fieldIt’s difficult to see the sun’s magnetic field lines, which loop through the solar atmosphere to form a complicated web of magnetic structures far more complex than Earth’s magnetic field. To better grasp how the sun’s magnetic field works, scientists turn to mathematical models. Like the 11-year solar magnetic cycle, torsional oscillations also experience an 11-year cycle.

The lunar standstill is when the northernmost and southernmost moonrise and moonset are farthest apart. Stonehenge's station stones are thought by some to be aligned with the lunar standstill. Ruggles said that Stonehenge’s station stones, which form a rectangle around the circle, roughly align with the moon’s extreme positions during the lunar standstill. However, it’s much more difficult to say whether Stonehenge really has a connection to the lunar standstill.

Einstein's general theory of relativity states that the curvature of space-time causes gravity. But zoom out to enormous scales like clusters of galaxies spanning billions of light years across, and the laws of Einstein's gravity theory appear to change. A 1% adjustment may not sound like a big deal, but it's enough to suggest that Einstein's theory may need a rethink. Now, with this cosmic glitch, there's a new explanation on the table. NASA/CXC/Univ of Missouri/M.Brodwin et al; NASA/STScI; JPL/CalTechThe fact that this cosmic glitch could potentially help astronomers resolve the Hubble tension is a good sign that it may truly exist.

CNN —Toward the end of its 35th season, “The Simpsons” made a move that rankled some fans: It killed a longtime resident of Springfield. I would say under 10,” said Matt Selman, sardonic showrunner of “The Simpsons,” in an interview with CNN. There are around 16 writers per season, typically made up of 22 episodes, though this season has just 18 due to the 2023 writers’ and actors’ strikes. Last month, Sosthand won a Writers Guild Award for the episode, beating out three other nominees from the “Simpsons” writers room. It’s nice that their hard work has been noticed, Selman said, but critical appraisal of “The Simpsons” is always in flux.

Using telescopes capable of detecting X-rays, a team of astronomers has for the first time observed this area — called the “plunging region” — in a black hole about 10,000 light-years from Earth. The study’s findings could help astronomers better understand the formation and evolution of black holes. One thing that’s missing from the study is an actual image of the black hole, because it is too small and far away. But another team of Oxford researchers is working on something even better than a picture: the first movie of a black hole. “For example, it can be used to measure the rotation rate of the black hole,” said Reynolds, who was not involved in the study.
