Reptiles are astonishingly diverse, with extraordinary adaptations such as a tiny lizard in Costa Rica that has evolved a way to “scuba dive,” according to new research. Fantastic creaturesUsing the air bubble helps the anole to stay underwater longer, and the technique may help the tiny lizard hide from predators, researchers say. This ability allows the lizard to stay underwater for a prolonged period of time.

Along the way, Voyager 1 found a thin ring around Jupiter and two new Jovian moons as well as five new moons orbiting Saturn.

☆ Turbulent skies of Vincent Van Gogh’s ‘The Starry Night’ may align with a scientific theory
▼ + stars: | 2024-09-19 | by ( Katie Hunt | ) edition.cnn.com time to read: +8 min

CNN —The dappled starlight and swirling clouds of Vincent van Gogh’s “The Starry Night” are thought to reflect the artist’s tumultuous state of mind when he painted the work in 1889. Now, a new analysis by physicists based in China and France suggests the artist had a deep, intuitive understanding of the mathematical structure of turbulent flow. Batchelor’s scaling mathematically represents how small particles, such as drifting algae in the ocean or pieces of dust in the wind, are passively mixed around by turbulent flow. “I think this physical relationship must be embedded in his mind so that’s why when he made this famous ‘Starry Night’ painting, it mimics the real flow,” Huang said. “What I take away from studies like this is that (van Gogh) captured some of this universality in the beautiful (‘Starry Night’),” Beattie added.

London CNN —OpenAI has unveiled a new artificial intelligence model that it says can “reason” and solve harder problems in science, coding and math than its predecessors. The model, the first in a series called OpenAI o1, was released Thursday as a preview, with the firm saying it expects regular updates and improvements. “We trained these models to spend more time thinking through problems before they respond, much like a person would,” the maker of ChatGPT said on its website. The new OpenAI model doesn’t yet have many of the features “that make ChatGPT useful,” the firm said, like browsing the web for information, and uploading files and images. In tests, OpenAI o1 performs similarly to PhD students on difficult benchmark tasks in physics, chemistry and biology, according to the company.

☆ Nuclear clocks could surpass precision of atomic ones
▼ + stars: | 2024-09-10 | by ( Mindy Weisberger | ) edition.cnn.com time to read: +9 min

For this nuclear clock, the scientists used ultraviolet light to excite nuclear particles in an atom of thorium-229 embedded in solid crystal. For decades, atomic clocks have been used in GPS technologies, for space exploration and for keeping international time. The study of physics itself could be revolutionized by using nuclear clocks alongside atomic clocks, according to Zhang. “If the nuclear clock and the atomic clock transition frequency ratio is changing over time, it would be an indication of new physics.”Though there is still much progress to be made before nuclear clocks surpass the performance of atomic clocks — or replace them — these findings hint that such a time isn’t far off, Kolkowitz said. “As better UV laser sources are developed and as some of the mysteries and tricks of nuclear clocks get worked out, I expect that eventually some of the kinds of experiments we are currently doing in my lab to test relativity and search for new physics with atomic clocks will instead be performed with nuclear clocks,” Kolkowitz said.

Cofounded by Mesa Quantum CEO Sristy Agrawal and CTO Wale Lawal in 2023, the company has won a $1.9 million Space Force grant to demonstrate its alternative to GPS technology in military and civilian applications. J2 Ventures cofounder and managing partner, Alex Harstrick, told CNBC his fund backed Mesa Quantum in part because of the founders' extraordinary technical background. Harstrick said his fund hopes that Mesa Quantum will have its first demonstration of mass scale "atomic clocks" (quantum timing sensors) validated by a top-tier semiconductor manufacturing partner" in the next few years. "The U.S. government has established major initiatives to spur innovation in this area and is seeking to purchase a million quantum sensors each year -- if they can simply be mass-produced," she explained. With its grant funding and seed round in place, Agrawal said, Mesa Quantum will look to grow its team in Boulder, especially hiring atomic molecular and optical physicists, engineers and manufacturing experts this year.

Beneath the pit, some 370 miles of tunnels twist through solid rock, extending more than 1.5 miles below the surface. For 126 years, this site in Lead, S.D., housed the Homestake Mine, the deepest and most productive gold mine on the continent. In 2006, the Barrick Gold Corporation donated the mine to the state of South Dakota, which converted it into the largest subterranean laboratory in the United States, the Sanford Underground Research Facility. Although the lowest tunnels flooded after mining ceased, it is still possible to descend nearly a mile beneath the planet’s surface. Most of the scientists who do so are physicists conducting highly sensitive experiments that must be shielded from interfering cosmic rays.

☆ UK Nobel Prize-winning physicist Peter Higgs dies aged 94

London —Physicist Peter Higgs, whose theory of an undetected particle in the universe changed science and was vindicated by a Nobel prize-winning discovery half a century later, has died aged 94, the University of Edinburgh said on Tuesday. Higgs described himself as “incompetent” in the physics laboratory at school and at first preferred maths and chemistry. What came to be known as the Higgs boson would solve the riddle of where several fundamental particles get their mass from: by interacting with the invisible “Higgs field” that pervades space. That interaction, known as the “Brout-Englert-Higgs” mechanism, won Higgs and Belgium’s Francois Englert the Nobel prize in physics in 2013. CERN’s massive Large Hadron Collider finally proved to be the sledgehammer needed to crack the nut, and in 2012 two experiments there independently found the Higgs boson.

The idea is to create a huge sunshade and send it to a far away point between the Earth and the sun to block a small but crucial amount of solar radiation, enough to counter global warming. Scientists have calculated that if just shy of 2 percent of the sun’s radiation is blocked, that would be enough to cool the planet by 1.5 degrees Celsius, or 2.7 Fahrenheit, and keep Earth within manageable climate boundaries. The idea has been at the outer fringes of conversations about climate solutions for years. But as the climate crisis worsens, interest in sun shields has been gaining momentum, with more researchers offering up variations. There’s even a foundation dedicated to promoting solar shields.
