Neptune’s disappearing clouds linked to solar cycle
  + stars: | 2023-08-22 | by ( Kristen Rogers | ) edition.cnn.com   time to read: +6 min
The findings are “extremely exciting and unexpected, especially since Neptune’s previous period of low cloud activity was not nearly as dramatic and prolonged,” Chavez added. The findings also contradict the idea of the clouds being affected by Neptune’s four seasons, which each last about 40 years. Additionally, Neptune storms rising from the deep atmosphere do influence the planet’s cloud cover — but aren’t related to clouds formed in the upper atmosphere. That variable could interfere with studies looking at correlations between photochemically produced clouds and the solar cycle. More research could also suggest how long the near absence of clouds on Neptune might last.

ChatGPT has drawn users at a feverish pace and spurred Big Tech to release other AI chatbots. But ChatGPT, the latest in technology known as "large language model tools," doesn't speak with sentience and doesn't "think" the way people do. Other tech companies like Google and Meta have developed their own large language model tools, which use programs that take in human prompts and devise sophisticated responses. Other researchers seem to be taking more measured approaches with generative AI tools. He told Insider he's helping to experiment with a chat bot called "Rentervention," which is meant to support tenants.

It had been lifted from her own Instagram account — her favorite picture from a trip to Lake Tahoe with her best friend. Compared with his sister, who had been both an academic and an athletic superstar in high school, Charles was kind of a slacker — smart enough to take advanced classes like A.P. “We’re going to figure this out,” she assured him when he finally choked out a description of the Instagram account. All things that were portrayed on the account do not actually portray my true feelings about people of color. The account had started at a chain restaurant called the Melt that was known for its grilled-cheese sandwiches.

In the latest Equity Talk, she shares how she's overcoming biases in the VC and biotech fields. Verge Genomics works with data derived from brains and spinal cords donated by people after they die. That's really been helpful because they don't necessarily see the same kind of questions. But I think part of that is just showing them that there can be a new way of doing things. I think that's an area where naivete can be a benefit, when you have big technological hurdles to overcome.

A subatomic particle called the muon is wobbling far more than leading physics models can explain. Its unusual behavior could be evidence of a fifth force of nature or a new dimension. And the reason could be evidence of a new, fifth force of nature. But there are still cosmic wonders we don't understand — mysteries that the discovery of a fifth force of nature may help solve. One possible explanation is that the muons' behavior is dictated by a fifth force of nature.

Many other scientists greeted the announcement with skepticism because an earlier Nature paper by Dr. Dias describing a different and less practical superconducting material had already been retracted. The university had previously conducted three preliminary inquiries into Dr. Dias’s research and decided the concerns did not warrant further scrutiny. On Tuesday, Dr. Hamlin said he was pleased that the journal had taken his concerns seriously. He said there were two additional instances of apparent data duplication in Dr. Dias’s work that he hoped would also be reviewed. One involves another Nature paper; the other is what Dr. Hamlin describes as a duplication of data in Dr. Dias’s thesis.

Most solar storms are pretty harmless, but every so often, the sun can send hugely powerful storms. The Carrington Event of 1859 is widely considered to be the most powerful solar storm ever recorded. A huge solar flare like this one anticipated the 1989 solar storm. Why scientists are concerned about the next solar peakThe sun's activity is currently growing, and scientists are particularly concerned about the ongoing solar cycle. With enough warning, operators can put in place measures to protect infrastructure from the worst effect of solar storms.

CNN —A cosmic object in the shape of a glowing question mark has photobombed one of the latest images captured by NASA’s James Webb Space Telescope — and scientists think they know what it might be. The two have been observed and studied by space and ground-based telescopes since the 1950s, but the highly sensitive Webb telescope allowed for the highest-resolution and most detailed image yet. NASA/ESA/CSA/Joseph DePasquale (STScI)The Webb telescope illuminates information about the origins of our universe, but the appearance of this mysterious object in the background of this image leaves more questions than answers. The cosmic question mark hasn’t been closely observed or studied, so scientists aren’t exactly sure about the object’s origins and makeup. The question mark shape could also be “indicative of a merger where these two galaxies are interacting gravitationally,” Britt said.

The past three weeks have witnessed the dramatic rise and fall of a new candidate for the holy grail of materials science: a superconductor that works at room temperature. The public interest around LK-99 was a social phenomenon as much as a scientific one. The miraculous potential of superconductors is that they carry electricity over large distances with perfect efficiency. If we ever figure out how to manufacture them cheaply and make them work at room temperature rather than only at hundreds of degrees below zero, it would revolutionize our economy and help save the environment. Superconductors can also achieve feats like powerful magnetic fields and levitation in midair, enabling new categories of electronic devices, computers and modes of transportation.

The internet went wild over claims scientists discovered a room-temperature superconductor. Here's how a room-temperature superconductor could change everything:Revolutionize the medical industryMRI machines currently depend on liquid helium coolant to keep cool enough to operate. A room-temperature superconductor would go a step further in helping create these fields under normal conditions. With room-temperature superconductors, EV makers might be able to take a closer step towards delivering cheap battery-run cars. This is where room-temperature superconductors could one day step in.

Read moreWASHINGTON, Aug 10 (Reuters) - The peculiar wobble of a subatomic particle called a muon in a U.S. laboratory experiment is making scientists increasingly suspect they are missing something in their understanding of physics - perhaps some unknown particle or force. The experiment studied the wobble of muons as they traveled through a magnetic field. Casey was alluding to a principle called Lorentz invariance that holds that the laws of physics are the same everywhere. The researchers shot beams of muons into a donut-shaped superconducting magnetic storage ring measuring 50 feet (15 meters) in diameter.

CNN —Virgin Galactic — the space tourism company founded by British billionaire Richard Branson — is finally prepared to launch its first space tourists to the edge of the cosmos, a major step toward delivering on decades of promises. Meet the crewThis mission comes on the heels of the success of Virgin Galactic’s first commercial mission, which launched in June. Goodwin was one of the earliest ticket holders on Virgin Galactic, which opened its first sales more than a decade ago. Virgin Galactic has sold about 800 tickets, including 600 at prices up to $250,000 and another couple hundred at $450,000 per ticket. In the lead-up to 2023, Virgin Galactic had been undergoing a lengthy “enhancement” process to upgrade its flight hardware.

On July 24, a large team of researchers convened in Liverpool to unveil a single number related to the behavior of the muon, a subatomic particle that might open a portal to a new physics of our universe. All eyes were on a computer screen as someone typed in a secret code to release the results. The first number that popped out was met with exasperation: a lot of concerning gasps, oh-my-God’s and what-did-we-do-wrong’s. The new measurement matched exactly what the physicists had computed two years prior — now with twice the precision. “It really all comes down to that single number,” said Hannah Binney, a physicist at the Massachusetts Institute of Technology’s Lincoln Laboratory who worked on the muon measurement as a graduate student.

Atomic bombs work via a process called nuclear fission that involves atom splitting. Albert Einstein didn't make the first atomic bombs, but his famous equation explains how they work. Scene from the film "Oppenheimer," where Cillian Murphy stands next to the first ever atomic bomb to detonate. The scientists designed and completed two different types of atomic bombs because they weren't sure which method would work. Since scientists working on the Manhattan Project weren't quite sure if the plutonium bomb's implosion method would work, they decided to test one before it was used in the war.

Why nuclear fusion is so important for global energy needsWe see the colossal power of nuclear fusion in action every day — the sun. Meaning that unlike fossil fuels, nuclear fusion doesn't contribute to greenhouse gases in the atmosphere that are driving climate change. It was a major breakthrough and the first time a fusion experiment had ever generated an energy surplus. Why nuclear fusion beats nuclear fissionCurrent nuclear power plants use fission to make energy. While fission creates a chain reaction, nuclear fusion reactors of the future would not, avoiding the risk of a meltdown.

My wife said to me the other day that you know a song is great if singing it makes you feel you can actually sing. There is a chemical reaction that happens; the DNA of the song fuses with your chromosomes and becomes something new. Or you can meet them with a sense of possibility, grounded in reality, loosely tethered to something like hope. When we are young, we feel that way because we don’t know any better. Eventually you get to a place where you know all the ways it can go wrong and feel open anyway.

South Korean scientists claim to have made a superconductor, LK-99, that works at room temperature. But electricity that travels along a superconductor barely loses energy along the way. That's the premise behind LK-99, a possible superconductor material that scientists in South Korea say they have devised, which has been dominating headlines and social media posts in the past week or so. To that end, some experts are trying, but this holy grail has eluded scientists for many years, so the prospects are still a long way off, experts told Insider. "So low power energy chips is one major area in chip design."
