Ants learned to farm fungi during a mass extinction
Science - Posted On:2024-10-03 15:00:00 Source: arstechnica
We tend to think of agriculture as a human innovation. But insects beat us to it by millions of years. Various ant species cooperate with fungi, creating a home for them, providing them with nutrients, and harvesting them as food. This reaches the peak of sophistication in the leafcutter ants, which cut foliage and return it to feed their fungi, which in turn form specialized growths that are harvested for food. But other ant species cooperate with fungi—in some cases strains of fungus that are also found growing in their environment.
Genetic studies have shown that these symbiotic relationships are highly specific—a given ant species will often cooperate with just a single strain of fungus. A number of genes that appear to have evolved rapidly in response to strains of fungi take part in this cooperative relationship. But it has been less clear how the cooperation originally came about, partly because we don't have a good picture of what the undomesticated relatives of these fungi look like.
Now, a large international team of researchers has done a study that traces the relationships among a large collection of both fungi and ants, providing a clearer picture of how this form of agriculture evolved. And the history this study reveals suggests that the cooperation between ants and their crops began after the mass extinction that killed the dinosaurs, when little beyond fungi could thrive.
Social Media Sanctions Hit Conservatives More, But Due to Content Sharing, Study Says

A study published in Nature has found that conservative social media users were more likely to face sanctions, but attributes this to their higher propensity to share low-quality news rather than political bias. Researchers analyzed 9,000 Twitter users during the 2020 U.S. election, finding pro-Trump users were 4.4 times more likely to be suspended than pro-Biden users. However, they also shared significantly more links from sites rated as untrustworthy by both politically balanced groups and Republican-only panels. Similar patterns were observed across multiple datasets spanning 16 countries from 2016 to 2023. The study concludes that asymmetric enforcement can result from neutral policies when behavior differs between groups. Read more of this story at Slashdot.
ULA hasn’t given up on developing a long-lived cryogenic space tug
Science - Posted On:2024-10-03 13:00:00 Source: arstechnica
The second flight of United Launch Alliance's Vulcan rocket, planned for Friday morning, has a primary goal of validating the launcher's reliability for delivering critical US military satellites to orbit.
Tory Bruno, ULA's chief executive, told reporters Wednesday that he is "supremely confident" the Vulcan rocket will succeed in accomplishing that objective. The Vulcan's second test flight, known as Cert-2, follows a near-flawless debut launch of ULA's new rocket on January 8.
“As I come up on Cert-2, I’m pretty darn confident I’m going to have a good day on Friday, knock on wood," Bruno said. "These are very powerful, complicated machines."
Despite stricter regulations, Europe has issues with tattoo ink ingredients
Science - Posted On:2024-10-02 16:00:00 Source: arstechnica
Recently, chemists at Binghamton University learned that many tattoo inks in the US contain different pigments than those listed, or unlisted additives. One might expect the European Union, with its stricter regulations, to have fewer issues on that score, but according to a new paper published in the journal Analyst, that's not the case, particularly for green and blue tattoo inks. Most had components that were not listed on the label, and some included banned ingredients.
“Our work cannot say anything about the safety of tattoos, but we think it's an important first step in addressing the question ‘Are tattoos safe?’" said co-author John Swierk, a chemist at Binghamton University. “If we don't know what's in a bottle of tattoo ink, then we cannot figure out what might be causing an adverse event in the near and long term, whether that’s an allergic reaction or something more serious. As a team, we aren't anti-tattoo, we just believe that clients and artists have a right to know what's in the inks they are using.”
As previously reported, typical tattoo ink contains one or more pigments (which give the ink its color) within a "carrier package" to help deliver the pigments into the skin. The pigments are the same as those used in paints and textiles. They can be either small bits of solids or discrete molecules, such as titanium dioxide or iron oxide (for white or rust-brown colors, respectively). As for the carrier packages, most ink manufacturers use grain or rubbing alcohol, sometimes with a bit of witch hazel added to the mix to help the skin heal after the tattooing process. There may also be other additives to adjust the viscosity and keep pigment particles suspended in the carrier package.
For the first time since 1882, UK will have no coal-fired power plants
Science - Posted On:2024-09-30 16:00:01 Source: arstechnica
On Monday, the UK will see the closure of its last operational coal power plant, Ratcliffe-on-Soar, which has been operating since 1968. The closure of the plant, which had a capacity of 2,000 megawatts, will bring an end to the history of the country's coal use, which started with the opening of the first coal-fired power station in 1882. Coal played a central part in the UK's power system in the interim, in some years providing over 90 percent of its total electricity.
But a number of factors combined to place coal in a long-term decline: the growth of natural gas-powered plants and renewables, pollution controls, carbon pricing, and a government goal to hit net-zero greenhouse gas emissions by 2050.
It's difficult to overstate the importance of coal to the UK grid. It was providing over 90 percent of the UK's electricity as recently as 1956. The total amount of power generated continued to climb well after that, reaching a peak of 212 terawatt hours of production by 1980. And the construction of new coal plants was under consideration as recently as the late 2000s. According to the organization Carbon Brief's excellent timeline of coal use in the UK, continuing the use of coal with carbon capture was given consideration.
We’re only beginning to understand the historic nature of Helene’s flooding
Science - Posted On:2024-09-30 12:30:00 Source: arstechnica
As of Monday morning, if one wanted to grasp the historic nature of flooding from the remnants of Hurricane Helene in western parts of North Carolina and the surrounding areas, the logical place to begin is at the National Climatic Data Center.
This federal office maintains the world's largest climate data archive and provides historical perspective to put present-day weather conditions and natural disasters into context in a warming world due to climate change.
Unfortunately, the National Climatic Data Center is based in Asheville, North Carolina. As I write this, the center's website remains offline. That's because Asheville, a city in North Carolina's Blue Ridge Mountains, is the epicenter of catastrophic flooding from Hurricane Helene that has played out over the last week. The climate data facility is inoperable because water and electricity services in the region have entirely broken down due to flooding.
Engineers investigate another malfunction on SpaceX’s Falcon 9 rocket
Science - Posted On:2024-09-30 11:15:00 Source: arstechnica
SpaceX is investigating a problem with the Falcon 9 rocket's upper stage that caused it to reenter the atmosphere and fall into the sea outside of its intended disposal area after a Saturday launch with a two-man crew heading to the International Space Station.
The upper stage malfunction apparently occurred after the Falcon 9 successfully deployed SpaceX's Crew Dragon spacecraft carrying NASA astronaut Nick Hague and Russian cosmonaut Aleksandr Gorbunov on SpaceX's Crew-9 mission. Hague and Gorbunov safely arrived at the space station Sunday to begin a five-month stay at the orbiting research complex.
The Falcon 9's second stage Merlin vacuum engine fired for more than six minutes to place the Crew Dragon spacecraft into orbit after liftoff from Cape Canaveral Space Force Station, Florida. The engine was supposed to reignite later to steer the upper stage on a trajectory back into Earth's atmosphere for disposal over the South Pacific Ocean, ensuring the rocket doesn't remain in orbit as a piece of space junk.
Mars' Long-Lost Atmosphere Might Be Hiding in Plain Sight
science - Posted On:2024-09-30 07:45:01 Source: slashdot
Newsweek writes that the missing atmosphere of Mars "may be locked up in the planet's clay-rich surface, a new study by MIT geologists has suggested." According to the researchers, ancient water trickling through Mars' rocks could have triggered a series of chemical reactions, converting CO2 into methane and trapping the carbon in clay minerals for billions of years... The dominant explanation relies on an interaction between the sun's rays and gases in the atmosphere. Mars lost its protective magnetic field billions of years ago, likely allowing high-energy solar particles to strike the upper atmosphere, kicking molecules off into space, according to NASA... But this might not be the whole story. The researchers focused on a type of clay mineral called smectite, known for its ability to trap carbon. These minerals, abundant on Mars, contain tiny folds that can store carbon molecules for aeons. The study was published in the journal Science Advances. "There is plenty of evidence for a thick clay layer on the Martian surface. Almost 80 percent of satellite spectra detect these high-surface-area clay minerals on the Martian surface. Clay has been detected in craters as deep as 17 kilometers [10.5 miles]," [lead author Joshua] Murray said... Their model suggested that Mars' surface could contain up to 1.7 bar of CO2 — roughly 80 percent of its early atmospheric volume — sequestered as methane within clay deposits. This methane could still be present today, lying beneath the planet's dry and barren crust. "We know this process happens, and it is well-documented on Earth. And these rocks and clays exist on Mars," Oliver Jagoutz, the study's author, said in a statement. "So, we wanted to try and connect the dots." The discovery that Mars' ancient atmosphere could be hidden within its surface clays offers a new perspective on the planet's history and raises intriguing possibilities for future exploration. For example, if the sequestered carbon could be recovered and converted, it could serve as a propellant for future space missions between Earth, Mars and beyond. "In some ways, Mars' missing atmosphere could be hiding in plain sight," says the study's lead author — and the article adds that this raises some interesting possibilities. "For example, if the sequestered carbon could be recovered and converted, it could serve as a propellant for future space missions between Earth, Mars and beyond..."

Could Atom-Sized Black Holes Be Detected in Our Solar System?
science - Posted On:2024-09-29 23:45:00 Source: slashdot
Scientific American has surprising news about the possibility of black holes the size of an atom but containing the mass of an asteroid — the so-called "primordial black holes" formed after the birth of the universe which could solve the ongoing mystery of the missing dark matter. These atom-sized black holes "may fly through the inner solar system about once a decade, scientists say... And if they sneak by the moon or Mars, scientists should be able to detect them, a new study shows." If one of these black holes comes near a planet or large moon, it should push the body off course enough to be measurable by current instruments. "As it passes by, the planet starts to wobble," says Sarah R. Geller, a theoretical physicist now at the University of California, Santa Cruz, and co-author of the study, which was published on September 17 in Physical Review D. "The wobble will grow over a few years but eventually it will damp out and go back to zero." Study team member Tung X. Tran, then an undergraduate student at the Massachusetts Institute of Technology, built a computer model of the solar system to see how the distance between Earth and nearby solar system objects would change after a black hole flyby. He found that such an effect would be most noticeable for Mars, whose distance scientists know within about 10 centimeters. For a black hole in the middle of the mass range, "we found that after three years the signal would grow to between one to three meters," Tran says. "That's way above the threshold of precision that we can measure." The Earth-Mars distance is particularly well tracked because scientists have been sending generations of probes and landers to the Red Planet... In a coincidence, an independent team published a paper about its search for signs of primordial black holes flying near Earth in the same issue of Physical Review D. The researchers' simulations found that such signals could be detectable in orbital data from Global Navigation Satellite Systems, as well as gravimeters that measure variations in Earth's gravitational field. "For decades physicists thought dark matter was likely to take the form of so-called weakly interacting massive particles (WIMPs)," the article points out. "Yet generations of ever more sensitive experiments meant to find these particles have come up empty." California astrophysicist Kevork Abazajian tells the site that now in the scientific community, "Primordial black holes are really gaining popularity." Read more of this story at Slashdot.
SpaceX Pausing Launches to Study Falcon 9 Issue on Crew-9 Astronaut Mission
science - Posted On:2024-09-29 14:45:00 Source: slashdot
"SpaceX has temporarily grounded its Falcon 9 rocket," reports Space.com, "after the vehicle experienced an issue on the Crew-9 astronaut launch for NASA." Crew-9 lifted off on Saturday (Sept. 28) from Florida's Cape Canaveral Space Force Station, sending NASA astronaut Nick Hague and Russian cosmonaut Aleksandr Gorbunov aloft aboard the Crew Dragon capsule "Freedom" [for a 5-month stay, returning in February with Starliner's two astronauts]. Everything appeared to go well. The Falcon 9's first stage aced its landing shortly after liftoff, and the rocket's upper stage deployed Freedom into its proper orbit; the capsule is on track to arrive at the International Space Station (ISS) on Sunday afternoon (Sept. 29) as planned. But the upper stage experienced an issue after completing that job, SpaceX announced early Sunday morning. "After today's successful launch of Crew-9, Falcon 9's second stage was disposed in the ocean as planned, but experienced an off-nominal deorbit burn. As a result, the second stage safely landed in the ocean, but outside of the targeted area. We will resume launching after we better understand root cause," SpaceX wrote in a post on X. Indeed, a Falcon 9 had been scheduled to launch 20 broadband satellites for the company Eutelsat OneWeb from Vandenberg Space Force Base in California on Sunday night, but that liftoff has been postponed.

America's FDA Approves First New Drug for Schizophrenia in Over 30 Years
science - Posted On:2024-09-29 11:45:01 Source: slashdot
Thursday America's Food and Drug Administration approved Cobenfy, "the first new drug to treat people with schizophrenia in more than 30 years," reports ABC News: Most schizophrenia medications, broadly known as antipsychotics, work by changing dopamine levels, a brain chemical that affects mood, motivation, and thinking [according to Jelena Kunovac, MD, a board-certified psychiatrist and adjunct assistant professor at the University of Nevada, Las Vegas, in the Department of Psychiatry]. Cobenfy takes a different approach by adjusting acetylcholine, another brain chemical that aids memory, learning and attention, she said. By focusing on acetylcholine instead of dopamine, Cobenfy may reduce schizophrenia symptoms while avoiding common side effects like weight gain, drowsiness and movement disorders, clinical trials suggest. These side effects often become so severe and unpleasant that, in some studies mirroring real-world challenges, many patients stopped treatment within 18 months of starting it. In clinical trials, only 6% of patients stopped taking Cobenfy due to side effects, noted Dr. Samit Hirawat, chief medical officer at Bristol Myers Squibb. "That's a significant improvement over the 20-30% seen with older antipsychotic drugs," he added... Schizophrenia is a mental health disorder that affects about 24 million people worldwide, or roughly one in 300 people, according to the World Health Organization. "Studies for additional therapeutic uses, including the treatment of Alzheimer's disease and bipolar disorder, are also underway." Read more of this story at Slashdot.
Your cells are dying. All the time.
Science - Posted On:2024-09-29 07:45:00 Source: arstechnica
Billions of cells die in your body every day. Some go out with a bang, others with a whimper.
They can die by accident if they’re injured or infected. Alternatively, should they outlive their natural lifespan or start to fail, they can carefully arrange for a desirable demise, with their remains neatly tidied away.
Originally, scientists thought those were the only two ways an animal cell could die, by accident or by that neat-and-tidy version. But over the past couple of decades, researchers have racked up many more novel cellular death scenarios, some specific to certain cell types or situations. Understanding this panoply of death modes could help scientists save good cells and kill bad ones, leading to treatments for infections, autoimmune diseases, and cancer.
SpaceX launches mission to bring Starliner astronauts back to Earth

NASA astronaut Nick Hague and Russian cosmonaut Aleksandr Gorbunov lifted off Saturday from Florida's Space Coast aboard a SpaceX Dragon spacecraft, heading for a five-month expedition on the International Space Station.
The two-man crew launched on top of SpaceX's Falcon 9 rocket at 1:17 pm EDT (17:17 UTC), taking an advantage of a break in stormy weather to begin a five-month expedition in space. Nine kerosene-fueled Merlin engines powered the first stage of the flight on a trajectory northeast from Cape Canaveral Space Force Station, then the booster detached and returned to landing at Cape Canaveral as the Falcon 9's upper stage accelerated SpaceX's Crew Dragon Freedom spacecraft into orbit.
"It was a sweet ride," Hague said after arriving in space. With a seemingly flawless launch, Hague and Gorbunov are on track to arrive at the space station around 5:30 pm EDT (2130 UTC) Sunday.
An International Space Station Leak Is Getting Worse, NASA Confirms
science - Posted On:2024-09-28 15:00:00 Source: slashdot
Ars Technica reports NASA officials operating the International Space Station "are seriously concerned about a small Russian part of the station" — because it's leaking. The "PrK" tunnel connecting a larger module to a docking port "has been leaking since September 2019... In February of this year NASA identified an increase in the leak rate from less than 1 pound of atmosphere a day to 2.4 pounds a day, and in April this rate increased to 3.7 pounds a day." A new report, published Thursday by NASA's inspector general, provides details not previously released by the space agency that underline the severity of the problem... Despite years of investigation, neither Russian nor US officials have identified the underlying cause of the leak. "Although the root cause of the leak remains unknown, both agencies have narrowed their focus to internal and external welds," the report, signed by Deputy Inspector General George A. Scott, states. The plan to mitigate the risk is to keep the hatch on the Zvezda module leading to the PrK tunnel closed. Eventually, if the leak worsens further, this hatch might need to be closed permanently, reducing the number of Russian docking ports on the space station from four to three. Publicly, NASA has sought to minimize concerns about the cracking issue because it remains, to date, confined to the PrK tunnel and has not spread to other parts of the station. Nevertheless, Ars reported in June that the cracking issue has reached the highest level of concern on the space agency's 5x5 "risk matrix" to classify the likelihood and consequence of risks to spaceflight activities. The Russian leaks are now classified as a "5" both in terms of high likelihood and high consequence. "According to NASA, Roscosmos is confident they will be able to monitor and close the hatch to the Service Module prior to the leak rate reaching an untenable level. However, NASA and Roscosmos have not reached an agreement on the point at which the leak rate is untenable." The article adds that the Space Station should reach its end of life by either 2028 or 2030, and NASA "intends to transition its activities in low-Earth orbit onto private space stations," and has funded Axiom Space, Blue Origin, and Voyager Space for initial development. "There is general uncertainty as to whether any of the private space station operators will be ready in 2030." Read more of this story at Slashdot.
Alcohol Can Increase Your Cancer Risk, Researchers Find
science - Posted On:2024-09-28 14:00:01 Source: slashdot
The world's oldest and largest cancer research association "found excessive levels of alcohol consumption increase the risk for six different types of cancer," reports CBS News: "Some of this is happening through chronic inflammation. We also know that alcohol changes the microbiome, so those are the bacteria that live in your gut, and that can also increase the risk," Dr. C�line Gounder, CBS News medical contributor and editor-at-large for public health at KFF Health News, recently said on "CBS Mornings." But how much is too much when it comes to drinking? We asked experts what to know. "Excessive levels of alcohol" equates to about three or more drinks per day for women and four or more drinks per day for men, Gounder said... Other studies have shown, however, there is no "safe amount" of alcohol, Gounder said, particularly if you have underlying medical conditions. "If you don't drink, don't start drinking. If you do drink, really try to keep it within moderation," she said. Dr. Amy Commander, medical director of the Mass General Cancer Center specializing in breast cancer, told CBS News alcohol is the third leading modifiable risk factor that can increase cancer risk after accounting for cigarette smoking and excess body weight. [Other factors include physical inactivity — and diet]. "There really isn't a safe amount of alcohol for consumption," she said. "In fact, it's best to not drink alcohol at all, but that is obviously hard for many people. So I think it's really important for individuals to just be mindful of their alcohol consumption and certainly drink less." The article also includes an interesting statistic from the association's latest Cancer Progress Report: from 1991 to 2021 there's been a 33% reduction in overall cancer deaths in the U.S. That's 4.1 million lives saved — roughly 136,667 lives saved each year. "So that is hopeful," Commander said, adding that when it comes to preventing cancer, alcohol is just "one piece of the puzzle." Read more of this story at Slashdot.
Octopuses Recorded Hunting With Fish - and Punching Those That Don't Cooperate
science - Posted On:2024-09-28 12:45:00 Source: slashdot
Slashdot reader Hmmmmmm shared this report from NBC News: Octopuses don't always hunt alone — but their partners aren't who you'd expect. A new study shows that some members of the species Octopus cyanea maraud around the seafloor in hunting groups with fish, which sometimes include several fish species at once. The research, published in the journal Nature on Monday, even suggests that the famously intelligent animals organized the hunting groups' decisions, including what they should prey upon. What's more, the researchers witnessed the cephalopod species — often called the big blue or day octopus — punching companion fish, apparently to keep them on task and contributing to the collective effort... "If the group is very still and everyone is around the octopus, it starts punching, but if the group is moving along the habitat, this means that they're looking for prey, so the octopus is happy. It doesn't punch anyone..." [said Eduardo Sampaio, a postdoctoral researcher at the Max Planck Institute of Animal Behavior and the lead author of the research]. NBC News says the study is "an indication that at least one octopus species has characteristics and markers of intelligence that scientists once considered common only in vertebrates." Lead author Sampaio agrees that "We are very similar to these animals. In terms of sentience, they are at a very close level or closer than we think toward us." Read more of this story at Slashdot.

Jets From Black Holes Cause Stars To Explode, Hubble Reveals
science - Posted On:2024-09-28 06:15:00 Source: slashdot
Black hole jets, which spew near-light-speed particle beams, can trigger nearby white dwarf stars to explode by igniting hydrogen layers on their surfaces. "We don't know what's going on, but it's just a very exciting finding," said Alec Lessing, an astrophysicist at Stanford University and lead author of a new study describing the phenomenon, in an ESA release. Gizmodo reports: In the recent work -- set to publish in The Astrophysical Journal and is currently hosted on the preprint server arXiv -- the team studied 135 novae in the galaxy M87, which hosts a supermassive black hole of the same name at its core. M87 is 6.5 billion times the mass of the Sun and was the first black hole to be directly imaged, in work done in 2019 by the Event Horizon Telescope Collaboration. The team found twice as many novae erupting near M87's 3,000 light-year-long plasma jet than elsewhere in the galaxy. The Hubble Space Telescope also directly imaged M87's jet, which you can see below in luminous blue detail. Though it looks fairly calm in the image, the distance deceives you: this is a long tendril of superheated, near-light speed particles, somehow triggering stars to erupt. Though previous researchers had suggested there was more activity in the jet's vicinity, new observations with Hubble's wider-view cameras revealed more of the novae brightening -- indicating they were blowing hydrogen up off their surface layers. "There's something that the jet is doing to the star systems that wander into the surrounding neighborhood. Maybe the jet somehow snowplows hydrogen fuel onto the white dwarfs, causing them to erupt more frequently," Lessing said in the release. "But it's not clear that it's a physical pushing. It could be the effect of the pressure of the light emanating from the jet. When you deliver hydrogen faster, you get eruptions faster." The new Hubble images of M87 are also the deepest yet taken, thanks to the newer cameras on Hubble. Though the team wrote in the paper that there's between a 0.1% to 1% chance that their observations can be chalked up to randomness, most signs point to the jet somehow catalyzing the stellar eruptions.

Black hole jet appears to boost rate of nova explosions
Science - Posted On:2024-09-27 18:00:00 Source: arstechnica
The intense electromagnetic environment near a black hole can accelerate particles to a large fraction of the speed of light and sends the speeding particles along jets that extend from each of the object's poles. In the case of the supermassive black holes found in the center of galaxies, these jets are truly colossal, blasting material not just out of the galaxy, but possibly out of the galaxy's entire neighborhood.
But this week, scientists have described how the jets may be doing some strange things inside of a galaxy, as well. A study of the galaxy M87 showed that nova explosions appear to be occurring at an unusual high frequency in the neighborhood of one of the jets from the galaxy's central black hole. But there's absolutely no mechanism to explain why this might happen, and there's no sign that it's happening at the jet that's traveling in the opposite direction.
Whether this effect is real, and whether we can come up with an explanation for it, may take some further observations.
Europe's Space Agency Will Destroy a Brand-New Satellite in 2027 Just To See What Happens
science - Posted On:2024-09-27 15:45:00 Source: slashdot
The European Space Agency (ESA) plans to launch a satellite into Earth's orbit in 2027 to watch it get wrecked as it reenters the atmosphere. From a report: The project is intended to help understand how exactly satellites break apart so that scientists can learn how to prevent the creation of more space debris. Space junk is becoming a bigger problem as we send more satellites into orbit, but there are efforts to try and address it. This mission is part of the ESA's Zero Debris Charter initiative to stop the creation of additional space debris by 2030. The mission is called the Destructive Reentry Assessment Container Object (DRACO), and the insides of the satellite will collect data as the craft gets destroyed during reentry into the atmosphere. It will also contain a 40-centimeter capsule designed to survive the destruction that will transmit the collected data as the capsule moves toward the ocean. Read more of this story at Slashdot.
