White House works to ground NASA science missions before Congress can act

fivenewscrypto    juillet 02, 2025   

In another sign that the Trump White House is aggressively moving to slash NASA’s science programs, dozens of mission leaders have been asked to prepare "closeout" plans by the end of next week.

The new directive came from NASA's senior leadership on Monday, which is acting on behalf of the White House Office of Management and Budget. Copies of these memos, which appear to vary a little by department, were reviewed by Ars. The detailed closeout plans called for must be prepared by as soon as July 9 for some missions, which has left principal investigators scrambling due to the tight deadline and the July 4 holiday weekend.

Projects should prepare their plans assuming closeout direction is given on October 1, 2025, one of the NASA memos states. Missions in operations—that is to say, spacecraft whizzing around the Solar System conducting science right now—should "assume closeout is complete within 3 months."

Tuesday Telescope: A howling wolf in the night sky

Tuesday Telescope: A howling wolf in the night sky

In the 1800s, astronomers were mystified by the discovery of stars that displayed highly unusual emission lines. It was only after 1868, when scientists discovered the element helium, that astronomers were able to explain the broad emission bands due to the presence of helium in these stars.

Over time, these stars became known as Wolf-Rayet stars (Charles Wolf was a French astronomer, and helium was first detected by the French scientist Georges Rayet and others), and astronomers came to understand that they were the central stars within planetary nebulae, and continually ejecting gas at high velocity.

This gives Wolf-Rayet stars a distinctive appearance in the night sky. And this week, Chris McGrew has shared a photo of WR 134—a variable Wolf-Rayet star about 6,000 light-years away from Earth in the constellation of Cygnus—which he captured from a dark sky location in southwestern New Mexico.

A mammoth tusk boomerang from Poland is 40,000 years old

A mammoth tusk boomerang from Poland is 40,000 years old

fivenewscrypto    juillet 02, 2025   

A boomerang carved from a mammoth tusk is one of the oldest in the world, and it may be even older than archaeologists originally thought, according to a recent round of radiocarbon dating.

Archaeologists unearthed the mammoth-tusk boomerang in Poland’s Oblazowa Cave in the 1990s, and they originally dated it to around 18,000 years old, which made it one of the world’s oldest intact boomerangs. But according to recent analysis by University of Bologna researcher Sahra Talamo and her colleagues, the boomerang may have been made around 40,000 years ago. If they’re right, it offers tantalizing clues about how people lived on the harsh tundra of what’s now Poland during the last Ice Age.

The mammoth-tusk boomerang is about 72 centimeters long, gently curved, and shaped so that one end is slightly more rounded than the other. It still bears scratches and scuffs from the mammoth’s life, along with fine, parallel grooves that mark where some ancient craftsperson shaped and smoothed the boomerang. On the rounded end, a series of diagonal marks would have made the weapon easier to grip. It’s smoothed and worn from frequent handling: the last traces of the life of some Paleolithic hunter.

Analyst: M5 Vision Pro, Vision Air, and smart glasses coming in 2026–2028

Analyst: M5 Vision Pro, Vision Air, and smart glasses coming in 2026–2028

fivenewscrypto    juillet 02, 2025   

Apple's Vision Pro hasn't made huge waves in the market, partly due to its steep price and "everything including the kitchen sink" feature set. But Apple hasn't given up on the platform yet; a prominent analyst with a strong record of accurate projections for Apple's product lineup, Ming-Chi Kuo, published a roadmap that shows Apple beginning to roll out a new wave of mixed reality devices in 2027.

Kuo says Apple still "views head-mounted devices as the next major trend in consumer electronics." We already knew Apple CEO Tim Cook felt that way before the Vision Pro came out, but continued investment seems to indicate that Apple hasn't been dissuaded by the relatively low sales of the Vision Pro as a niche product. However, Kuo notes that "Apple is not expected to launch any new head-mounted devices in 2026."

Launches are planned for 2027 and 2028, though. You might expect a sort of Vision Pro 2, and Kuo believes that's coming—but not until at least mid-2028. When it arrives, it's expected to jump from Apple's M2 system-on-a-chip to the M5, which should offer a significant performance leap. Based on his supply line sources, Kuo believes the new headset will feature a completely new design that is "significantly" lighter than the first Vision Pro and a lower price point.

Research roundup: 6 cool science stories we almost missed

Research roundup: 6 cool science stories we almost missed

fivenewscrypto    juillet 02, 2025   

It's a regrettable reality that there is never enough time to cover all the interesting scientific stories we come across each month. In the past, we've featured year-end roundups of cool science stories we (almost) missed. This year, we're experimenting with a monthly collection. June's list includes the final results from the Muon g-2 experiment, re-creating the recipe for Egyptian blue, embedding coded messages in ice bubbles, and why cats seem to have a marked preference for sleeping on their left sides.

Re-creating Egyptian blues

Artists in ancient Egypt were particularly fond of the color known as Egyptian blue—deemed the world's oldest synthetic pigment—since it was a cheap substitute for pricier materials like lapis lazuli or turquoise. But archaeologists have puzzled over exactly how it was made, particularly given the wide range of hues, from deep blue to gray or green. That knowledge had long been forgotten. However, scientists at Washington State University have finally succeeded in recreating the recipe, according to a paper published in the journal npj Heritage Science.

The interdisciplinary team came up with 12 different potential recipes using varying percentages of silicon dioxide, copper, calcium, and sodium carbonate. They heated the samples to 1,000° Celsius (about what ancient artists could have achieved), varying the time between one and 11 hours. They also cooled the samples at different rates. Then they analyzed the samples using microscopy and other modern techniques and compared them to the Egyptian blue on actual Egyptian artifacts to find the best match.

Drug cartel hacked FBI official’s phone to track and kill informants, report says

Drug cartel hacked FBI official’s phone to track and kill informants, report says

fivenewscrypto    juillet 02, 2025   

The Sinaloa drug cartel in Mexico hacked the phone of an FBI official investigating kingpin Joaquín “El Chapo” Guzmán as part of a surveillance campaign “to intimidate and/or kill potential sources or cooperating witnesses,” according to a recently published report by the Justice Department.

The report, which cited an “individual connected to the cartel,” said a hacker hired by its top brass “offered a menu of services related to exploiting mobile phones and other electronic devices.” The hired hacker observed “'people of interest' for the cartel, including the FBI Assistant Legal Attache, and then was able to use the [attache's] mobile phone number to obtain calls made and received, as well as geolocation data, associated with the [attache's] phone."

“According to the FBI, the hacker also used Mexico City's camera system to follow the [attache] through the city and identify people the [attache] met with,” the heavily redacted report stated. “According to the case agent, the cartel used that information to intimidate and, in some instances, kill potential sources or cooperating witnesses.”

Half a million Spotify users are unknowingly grooving to an AI-generated band

Half a million Spotify users are unknowingly grooving to an AI-generated band

fivenewscrypto    juillet 01, 2025   

Making art used to be a uniquely human endeavor, but machines have learned to distill human creativity with generative AI. Whether that content counts as "art" depends on who you ask, but Spotify doesn't discriminate. A new band called The Velvet Sundown debuted on Spotify this month and has already amassed more than half a million listeners. But by all appearances, The Velvet Sundown is not a real band—it's AI.

While many artists are vehemently opposed to using AI, some have leaned into the trend to assist with music production. However, it doesn't seem like there's an artist behind this group. In less than a month, The Velvet Sundown has released two albums on Spotify, titled "Floating On Echoes" and "Dust and Silence." A third album is releasing in two weeks. The tracks have a classic rock vibe with a cacophony of echoey instruments and a dash of autotune. If one of these songs came up in a mix, you might not notice anything is amiss. Listen to one after another, though, and the bland muddiness exposes them as a machine creation.

Some listeners began to have doubts about The Velvet Sundown's existence over the past week, with multiple Reddit and X threads pointing out the lack of verifiable information on the band. The bio lists four members, none of whom appear to exist outside of The Velvet Sundown's album listings and social media. The group's songs have been mysteriously added to a large number of user-created playlists, which has helped swell its listener base in a few short weeks. When Spotify users began noticing The Velvet Sundown's apparent use of AI, the profile had around 300,000 listeners. It's now over 500,000 in less than a week.
