If you need any inspiration for cutting loose and relaxing this weekend, look no further than a free-wheeling troop of monkeys that broke out of their South Carolina research facility Wednesday and, as of noon Friday, were still "playfully exploring" with their newfound freedom.
In an update Friday, the police department of Yemassee, SC said that the 43 young, female rhesus macaque monkeys are still staying around the perimeter of the Alpha Genesis Primate Research Facility. "The primates are exhibiting calm and playful behavior, which is a positive indication," the department noted.
The fun-loving furballs got free after a caretaker "failed to secure doors" at the facility.
The global space community awoke to a new reality on Wednesday morning.
The founder of this century's most innovative space company, Elon Musk, successfully used his fortune, time, and energy to help elect Donald Trump to president of the United States. Already, Musk was the dominant Western player in space. SpaceX launches national security satellites and NASA astronauts and operates a megaconstellation. He controls the machines that provide essential space services to NASA and the US military. And now, thanks to his gamble on backing Trump, Musk has strong-armed himself into Trump's inner circle.
Although he may not have a cabinet-appointed position, Musk will have a broad portfolio in the new administration for as long as his relations with Trump remain positive. This gives Musk extraordinary power over a number of areas, including spaceflight. Already this week, he has been soliciting ideas and input from colleagues. The New York Times reported that Musk has advised Trump to hire key employees from SpaceX into his administration, including at the Department of Defense. This reflects the huge conflict of interest that Musk will face when it comes to space policy. His actions could significantly benefit SpaceX, of which he is the majority owner and has the final say in major decisions.
People have long been fascinated by the haunting plaster casts of the bodies of people who died in Pompeii when Mount Vesuvius erupted in 79 CE. Archaeologists have presented certain popular narratives about who these people might have been and how they might have been related. But ancient DNA analysis has revealed that those preferred narratives were not entirely accurate and may reflect certain cultural biases, according to a new paper published in the journal Current Biology. The results also corroborate prior research suggesting that the people of ancient Pompeii were the descendants of immigrants from the Eastern Mediterranean.
As previously reported, the eruption of Mount Vesuvius released thermal energy roughly equivalent to 100,000 times the atomic bombs dropped on Hiroshima and Nagasaki at the end of World War II, spewing molten rock, pumice, and hot ash over the cities of Pompeii and Herculaneum in particular. The vast majority of people in Pompeii and Herculaneum—the cities hardest hit—perished from asphyxiation, choking on the thick clouds of noxious gas and ash. But at least some of the Vesuvian victims probably died instantaneously from the intense heat of fast-moving lava flows, with temperatures high enough to boil brains and explode skulls.
In the first phase, immediately after the eruption, a long column of ash and pumice blanketed the surrounding towns, most notably Pompeii and Herculaneum. By late night or early morning, pyroclastic flows (fast-moving hot ash, lava fragments, and gases) swept through and obliterated what remained, leaving the bodies of the victims frozen in seeming suspended action.
Welcome to Edition 7.19 of the Rocket Report! Okay, we get it. We received more submissions from our readers on Australia's approval of a launch permit for Gilmour Space than we've received on any other news story in recent memory. Thank you for your submissions as global rocket activity continues apace. We'll cover Gilmour in more detail as they get closer to launch. There will be no Rocket Report next week as Eric and I join the rest of the Ars team for our 2024 Technicon in New York.
As always, we welcome reader submissions. If you don't want to miss an issue, please subscribe using the box below (the form will not appear on AMP-enabled versions of the site). Each report will include information on small-, medium-, and heavy-lift rockets as well as a quick look ahead at the next three launches on the calendar.
Gilmour Space has a permit to fly. Gilmour Space Technologies has been granted a permit to launch its 82-foot-tall (25-meter) orbital rocket from a spaceport in Queensland, Australia. The space company, founded in 2012, had initially planned to lift off in March but was unable to do so without approval from the Australian Space Agency, the Australian Broadcasting Corporation reports. The government approved Gilmour's launch permit Monday, although the company is still weeks away from flying its three-stage Eris rocket.
In a long-sought move, the Food and Drug Administration on Thursday formally began the process of abandoning oral doses of a common over-the-counter decongestant, which the agency concluded last year is not effective at relieving stuffy noses.
Specifically, the FDA issued a proposed order to remove oral phenylephrine from the list of drugs that drugmakers can include in over-the-counter products—also known as the OTC monograph. Once removed, drug makers will no longer be able to include phenylephrine in products for the temporary relief of nasal congestion.
"It is the FDA’s role to ensure that drugs are safe and effective," Patrizia Cavazzoni, director of the FDA’s Center for Drug Evaluation and Research, said in a statement. "Based on our review of available data and consistent with the advice of the advisory committee, we are taking this next step in the process to propose removing oral phenylephrine because it is not effective as a nasal decongestant."
Since the 1940s, baseball players have been spreading a special kind of "magic mud" on new baseballs to reduce the slick, glossy shine and give pitchers a firmer grip. Now, scientists at the University of Pennsylvania have identified just what gives that magic mud its special properties, according to a new paper published in the Proceedings of the National Academy of Sciences.
Before magic mud came along, baseballs were treated with a mix of water and soil from the infield or, alternatively, tobacco juice or shoe polish. But these substances stained and scratched up the ball's leather surface. Lena Blackburne was a third-base coach for the Philadelphia Athletics in the 1930s when an umpire complained about that, so he hunted for a better mud. Blackburne found that mud in a still-secret location purportedly near Palmyra, New Jersey, and a baseball dynasty was born: Lena Blackburne Baseball Rubbing Mud. Once harvested, the mud is strained, skimmed of excess water, rinsed with tap water, and then subjected to a secret "proprietary treatment" before being allowed to settle.
Yet there hasn't been much scientific research on the magic mud apart from one 2022 study. We do know quite a bit about the complex behavior of soil in general, including mud. Per the authors, mud is essentially "a dense suspension of predominantly clay and silt particles in water," sometimes with a bit of sand in the mix, although this has little effect on how mud behaves under shearing forces (rheology). Technically, it falls into the non-Newtonian fluid category, in which the viscosity changes (either thickening or thinning) in response to an applied strain or shearing force, thereby straddling the boundary between liquid and solid behavior.
This suggests that microplastics in the air may affect weather and climate by producing clouds in conditions where they would not form otherwise.
We are atmosphericchemists who study how different types of particles form ice when they come into contact with liquid water. This process, which occurs constantly in the atmosphere, is called nucleation.
Clouds in the atmosphere can be made up of liquid water droplets, ice particles, or a mixture of the two. In clouds in the mid- to upper atmosphere where temperatures are between 32° and minus 36° F (0° to minus 38° C), ice crystals normally form around mineral dust particles from dry soils or biological particles, such as pollen or bacteria.
Ice in clouds has important effects on weather and climate because most precipitation typically starts as ice particles.
Many cloud tops in nontropical zones around the world extend high enough into the atmosphere that cold air causes some of their moisture to freeze. Then, once ice forms, it draws water vapor from the liquid droplets around it, and the crystals grow heavy enough to fall. If ice doesn’t develop, clouds tend to evaporate rather than causing rain or snowfall.
While children learn in grade school that water freezes at 32° F (0° C), that’s not always true. Without something to nucleate onto, such as dust particles, water can be supercooled to temperatures as low as minus 36° F (minus 38° C) before it freezes.
For freezing to occur at warmer temperatures, some kind of material that won’t dissolve in water needs to be present in the droplet. This particle provides a surface where the first ice crystal can form. If microplastics are present, they could cause ice crystals to form, potentially increasing rain or snowfall.
Clouds also affect weather and climate in several ways. They reflect incoming sunlight away from Earth’s surface, which has a cooling effect, and absorb some radiation that is emitted from Earth’s surface, which has a warming effect.
The amount of sunlight reflected depends on how much liquid water vs. ice a cloud contains. If microplastics increase the presence of ice particles in clouds compared with liquid water droplets, this shifting ratio could change clouds’ effect on Earth’s energy balance.
The Earth constantly receives energy from the Sun and reflects it back into space. Clouds have both warming and cooling effects in this process.

How we did our work
To see whether microplastic fragments could serve as nuclei for water droplets, we used four of the most prevalent types of plastics in the atmosphere: low-density polyethylene, polypropylene, polyvinyl chloride, and polyethylene terephthalate. Each was tested both in a pristine state and after exposure to ultraviolet light, ozone, and acids. All of these are present in the atmosphere and could affect the composition of the microplastics.
We suspended the microplastics in small water droplets and slowly cooled the droplets to observe when they froze. We also analyzed the plastic fragments’ surfaces to determine their molecular structure, since ice nucleation could depend on the microplastics’ surface chemistry.
For most of the plastics we studied, 50 percent of the droplets were frozen by the time they cooled to minus 8° F (minus 22° C). These results parallel those from another recent study by Canadian scientists, who also found that some types of microplastics nucleate ice at warmer temperatures than droplets without microplastics.
Exposure to ultraviolet radiation, ozone, and acids tended to decrease ice nucleation activity on the particles. This suggests that ice nucleation is sensitive to small chemical changes on the surface of microplastic particles. However, these plastics still nucleated ice, so they could still affect the amount of ice in clouds.
What still isn’t known
To understand how microplastics affect weather and climate, we need to know their concentrations at the altitudes where clouds form. We also need to understand the concentration of microplastics compared with other particles that could nucleate ice, such as mineral dust and biological particles, to see whether microplastics are present at comparable levels. These measurements would allow us to model the impact of microplastics on cloud formation.
Plastic fragments come in many sizes and compositions. In future research, we plan to work with plastics that contain additives, such as plasticizers and colorants, as well as with smaller plastic particles.
From its halo-like orbit nearly a million miles from Earth, the James Webb Space Telescope is seeing farther than human eyes have ever seen.
In May, astronomers announced that Webb detected the most distant galaxy found so far, a fuzzy blob of red light that we see as it existed just 290 million years after the Big Bang. Light from this galaxy, several hundreds of millions of times the mass of the Sun, traveled more than 13 billion years until photons fell onto Webb's gold-coated mirror.
A few months later, in July, scientists released an image Webb captured of a planet circling a star slightly cooler than the Sun nearly 12 light-years from Earth. The alien world is several times the mass of Jupiter and the closest exoplanet to ever be directly imaged. One of Webb's science instruments has a coronagraph to blot out bright starlight, allowing the telescope to resolve the faint signature of a nearby planet and use spectroscopy to measure its chemical composition.
Kids and teens can make some pretty hairbrained choices sometimes. But when a kid's choice is to engage in a TikTok challenge that threatens their life, psychiatrists can struggle to understand if it was just an exasperating poor choice born out of impulsivity and immaturity or something darker—an actual suicide attempt.
In a Viewpoint published today in JAMA Psychiatry, two psychiatrists from the University of Tennessee Health Science Center at Memphis raise the alarm about the dangers and complexities of TikTok challenges. They're an "emerging public health concern" for kids, the psychiatrists write, and they're blurring the lines between unintentional injuries and suicide attempts in children and teens.
The child and adolescent psychiatrists Onomeasike Ataga and Valerie Arnold say that their psychiatry team first saw injuries from TikTok challenges during the COVID-19 pandemic, but the trend has continued since the pandemic eased. Over recent years, they've seen children and teens hospitalized from a variety of challenges, including the "blackout challenge," in which participants attempt to choke themselves until they pass out; the "Benadryl challenge," in which participants ingest a large amount of the allergy medicine to get high and hallucinate; and the "fire challenge," in which participants pour a flammable liquid on their body and light it on fire. In these cases, the psychiatry team is sometimes called in to help assess whether the children and teens had an intent to self-harm. It's often hard to determine—and thus hard to decide on treatment recommendations.
Less than a month has passed since the historic fifth flight of SpaceX's Starship, during which the company caught the booster with mechanical arms back at the launch pad in Texas. Now, another test flight could come as soon as Nov. 18, the company announced Wednesday.
The improbable but successful recovery of the Starship first stage with "chopsticks" last month, and the on-target splashdown of the Starship upper stage halfway around the world, allowed SpaceX to avoid an anomaly investigation by the Federal Aviation Administration. Thus, the company was able to press ahead on a sixth test flight if it flew a similar profile.
And that's what SpaceX plans to do, albeit with some notable additions to the flight plan.
A Massachusetts spa owner has been arrested for what prosecutors describe as a blundering scheme in which she conspicuously smuggled counterfeit Botox and skin fillers into the US, then peddled them to clients by falsely claiming to be a nurse with a degree from "Havard" [sic] and a license from the state's "Estate Board."
Nevertheless, the woman—Rebecca Fadanelli, 38, of Stoughton—allegedly performed over 2,700 illegal injections between 2021 and 2024, raking in over $900,000 with the scam.
According to an affidavit from a special agent with the Food and Drug Administration, Fadanelli was smuggling in counterfeit Botox and fillers from China and Brazil. Between November 2023 and March 2024, Customs and Border Protection (CBP) seized at least six parcels from China addressed to Fadanelli or her employees. The packages included various counterfeit injectable drugs, including products labeled as Botox and skin fillers Sculptra and Juvederm.
The story of Arctic explorer Ernest Shackleton's failed 1914 expedition to be the first to traverse the continent of Antarctica has long captured the popular imagination, as have the various efforts to locate the wreckage of his ship, the Endurance. The ship was finally found in 2022, nearly 107 years after it sank beneath the ice. The stories of Shackleton's adventures and the 2022 expedition are told in parallel in Endurance, a new documentary from National Geographic now streaming on Disney+.
Endurance is directed by Oscar winners Jimmy Chin and Chai Vasarhelyi (Free Solo). According to Vasarhelyi, she and Chin had been obsessed with the Shackleton story for a long time. The discovery of the shipwreck in 2022 gave them the perfect opportunity to tell the story again for a new audience, making use of all the technological advances that have been made in recent years.
"I think the Shackleton story is at the heart of the DNA of our films," Vasarhelyi told Ars. "It's the greatest human survival story ever. It really speaks to having these audacious objectives and dreams. When everyone tells you that you can't, you want to do it anyway. It requires you to then have the actual courage, grit, discipline, and strength of character to see it through. Shackleton is that story. He didn't sensibly achieve any of his goals, but through his failure he found his strength: being able to inspire the confidence of his men."
The director of the National Reconnaissance Office has a message for US adversaries around the world.
"You can’t hide, because we’re constantly looking," said Chris Scolese, a longtime NASA engineer who took the helm of the US government's spy satellite agency in 2019.
The NRO is taking advantage of SpaceX's Starlink satellite assembly line to build a network of at least 100 satellites, and perhaps many more, to monitor adversaries around the world. So far, more than 80 of these SpaceX-made spacecraft, each a little less than a ton in mass, have launched on four Falcon 9 rockets. There are more to come.
A Cargo Dragon spacecraft docked to the International Space Station on Tuesday morning, less than a day after lifting off from Florida.
As space missions go, this one was fairly routine, ferrying about 6,000 pounds (2,700 kg) of cargo and science experiments to the space station. Over the course of nearly a dozen years, this was the 31st cargo supply mission that SpaceX has flown for NASA to the orbiting laboratory.
However, there is one characteristic of this flight that may prove significant for NASA and the future of the space station. As early as Friday, NASA and SpaceX have scheduled a "reboost and attitude control demonstration," during which the Dragon spacecraft will use some of the thrusters at the base of the capsule. This is the first time the Dragon spacecraft will be used to move the space station.
The Food and Drug Administration is warning consumers not to use any drugs made by a compounding pharmacy in California after regulators realized the pharmacy was making drugs that need to be sterile—particularly injectable drugs—without using sterile ingredients or any sterilization steps.
The products made by the pharmacy, Fullerton Wellness LLC, in Ontario, California, include semaglutide, which is intended to mimic brand-name weight-loss and diabetes drugs Wegovy and Ozempic. Fullerton also made tirzepatide, which is intended to mimic weight-loss and diabetes drugs Zepbound and Mounjaro.
The FDA became aware of the problem after a patient submitted a complaint to the regulator that a vial of semaglutide from Fullerton Wellness had an unidentified "black particulate" floating in it. Semaglutide, like tirzepatide, is injected under the skin and is intended to be sterile.
How did supermassive black holes end up at the center of every galaxy? A while back, it wasn't that hard to explain: That's where the highest concentration of matter is, and the black holes had billions of years to feed on it. But as we've looked ever deeper into the Universe's history, we keep finding supermassive black holes, which shortens the timeline for their formation. Rather than making a leisurely meal of nearby matter, these black holes have gorged themselves in a feeding frenzy.
With the advent of the Webb Space Telescope, the problem has pushed up against theoretical limits. The matter falling into a black hole generates radiation, with faster feeding meaning more radiation. And that radiation can drive off nearby matter, choking off the black hole's food supply. That sets a limit on how fast black holes can grow unless matter is somehow fed directly into them. The Webb was used to identify early supermassive black holes that needed to have been pushing against the limit for their entire existence.
But the Webb may have just identified a solution to the dilemma as well. It has spotted a black hole that appears to have been feeding at 40 times the theoretical limit for millions of years, allowing growth at a pace sufficient to build a supermassive black hole.
Henry VIII's favorite warship, the Mary Rose, sank in battle in 1545. Archaeologists successfully raised the ship in 1982, along with thousands of articles and the remains of 179 crew members—all remarkably well preserved thanks to the anaerobic conditions of the shipwreck created by the layers of soft sediment that accumulated over the wreckage.
A new analysis of some of the recovered bones reveals that whether someone is right- or left-handed could affect how their collarbone chemistry changes as they age, according to a new paper published in the journal PLoS ONE. This has implications for our understanding not just of aging, but of bone conditions like fracture risk and osteoarthritis.
As previously reported, the earliest-known reference to the Mary Rose appears in a January 29, 1510, letter ordering the construction of two new ships for the young king: the Mary Rose and her sister ship, dubbed the Peter Pomegranate. Once the newly built ship had launched, Henry VIII wasted no time defying his advisers and declaring war on France in 1512. The Mary Rose served the monarch well through that conflict, as well as during a second war with the French that ran roughly from 1522 through 1525, after which it underwent a substantial overhaul.
When Chinese space officials unveiled the design for the country's first super heavy lift rocket nearly a decade ago, it looked like a fairly conventional booster. The rocket was fully expendable, with three stages and solid motors strapped onto its sides.
Since then, the Asian country has been revising the design of this rocket, named Long March 9, in response to the development of reusable rockets by SpaceX. As of two years ago, China had recalibrated the design to have a reusable first stage.
Now, based on information released at a major airshow in Zhuhai, China, the design has morphed again. And this time, the plan for the Long March 9 rocket looks almost exactly like a clone of SpaceX's Starship rocket.
Fungi can be enigmatic organisms. Mushrooms or other structures may be visible above the soil, but beneath lurks a complex network of filaments, or hyphae, known as the mycelium. It is even possible for fungi to communicate through the mycelium—despite having no brain.
Other brainless life-forms (such as slime molds) have surprising ways of navigating their surroundings and surviving through communication. Wanting to see whether fungi could recognize food in different arrangements, researchers from Tohoku University and Nagaoka College in Japan observed how the mycelial network of Phanerochaete velutina, a fungus that feeds off dead wood, grew on and around wood blocks arranged in different shapes.
The way the mycelial network spread out, along with its wood decay activity, differed based on the wood block arrangements. This suggests communication because the fungi appeared to find where the most nutrients were and grow in those areas.
