A Florida homeowner has filed an unprecedented claim against NASA for damages caused by space debris that crashed through his roof in March. Alejandro Otero is seeking over $80,000 for property damage and other costs after a 1.6-pound metal object from the International Space Station struck his Naples home. NASA confirmed the debris was part of a battery pack jettisoned in 2021. Legal experts, cited by ArsTechnica in the linked story, say the agency's response could set a precedent for future cases involving space debris damage.

"It turns out that mathematicians actually can't agree on the definition of what makes two things equal, and that could cause some headaches for computer programs that are increasingly being used to check mathematical proofs," writes Clare Watson via ScienceAlert. The issue has prompted British mathematician Kevin Buzzard to re-examine the concept of equality to "challenge various reasonable-sounding slogans about equality." The research has been posted on arXiv. From the report: In familiar usage, the equals sign sets up equations that describe different mathematical objects that represent the same value or meaning, something which can be proven with a few switcharoos and logical transformations from side to side. For example, the integer 2 can describe a pair of objects, as can 1 + 1. But a second definition of equality has been used amongst mathematicians since the late 19th century, when set theory emerged. Set theory has evolved and with it, mathematicians' definition of equality has expanded too. A set like {1, 2, 3} can be considered 'equal' to a set like {a, b, c} because of an implicit understanding called canonical isomorphism, which compares similarities between the structures of groups.

"These sets match up with each other in a completely natural way and mathematicians realised it would be really convenient if we just call those equal as well," Buzzard told New Scientist's Alex Wilkins. However, taking canonical isomorphism to mean equality is now causing "some real trouble," Buzzard writes, for mathematicians trying to formalize proofs -- including decades-old foundational concepts -- using computers. "None of the [computer] systems that exist so far capture the way that mathematicians such as Grothendieck use the equal symbol," Buzzard told Wilkins, referring to Alexander Grothendieck, a leading mathematician of the 20th century who relied on set theory to describe equality.

Some mathematicians think they should just redefine mathematical concepts to formally equate canonical isomorphism with equality. Buzzard disagrees. He thinks the incongruence between mathematicians and machines should prompt math minds to rethink what exactly they mean by mathematical concepts as foundational as equality so computers can understand them. "When one is forced to write down what one actually means and cannot hide behind such ill-defined words," Buzzard writes. "One sometimes finds that one has to do extra work, or even rethink how certain ideas should be presented."

An anonymous reader quotes a report from the BBC: A vote against using MDMA as part of therapy for PTSD has provoked a powerful backlash among researchers who study psychedelic drugs. Some 13 million Americans struggle with post-traumatic stress disorder (PTSD). Existing therapies only bring relief for a fraction of patients, and new treatments are sorely needed, according to psychiatrists wrestling with the scale of the problem. So, there was distinct disappointment when an advisory committee at the US Food and Drug Administration (FDA) voted earlier this month against a therapy that many had hoped could offer the first new treatment for PTSD in 25 years. A number of experts who study psychedelics have since spoken out in support of MDMA-assisted therapy for PTSD and have sharply criticized the recommendations of the FDA's Psychopharmacological Drugs Advisory Committee. But some are still optimistic that the treatment might be approved when the FDA delivers its final decision in August.

While MDMA, also commonly known as ecstasy or molly, is listed as a Schedule 1 controlled substance in the US and so is illegal to use outside research, there has been a growing number of studies suggesting that when used with psychotherapy it could have potential for treating PTSD and some other mental health conditions. Ahead of the meeting, FDA approval of MDMA-assisted therapy for PTSD seemed likely, says Sandeep Nayak, an assistant professor of psychiatry at Johns Hopkins University, who investigates psychedelics as treatments for substance use and mood disorders. About two-thirds of people who received three sessions of MDMA and talk therapy no longer qualified for a PTSD diagnosis at the end of two Phase 3 clinical trials. It's an outcome that is "almost double that of existing medications", says Gul Dolen, a neuroscientist at the University of California, Berkeley, who researches the mechanisms of how psychedelics achieve therapeutic effects. "What's more, [the treatment] led to durable improvements in these patients lasting at least six months."

About half of people who enroll in current gold standard PTSD treatments drop out, which is "absurd," says Loree Sutton, a psychiatrist and retired Brigadier General in the US Army. She says new treatments are essential. "We have to do better." "Even if there are risks, we've got to figure this out, because we cannot not let this treatment be available," adds Rachel Yehuda, a professor of psychiatry and neuroscience at the Icahn School of Medicine at Mount Sinai who has conducted studies on the effects of MDMA-assisted therapy for PTSD. "Without it, we're just leaving too many people in suffering that they don't need to be in, and that is not right." The FDA is currently considering an application from California-based drug company Lykos Therapeutics for using MDMA capsules taken in conjunction with therapy in the treatment of PTSD. In the recent FDA advisory meeting, committee members cited apparent flaws in study design and data collection. The nine-hour hearing concluded with committee members voting 9-2 that the available data do not show "that the drug is effective" for PTSD, and voting 10-1 that the benefits of MDMA do not outweigh the risks.

An anonymous reader writes: Scientists have found microplastics in human penises for the first time, as concerns over the tiny particles' proliferation and potential health effects mount. Seven different kinds of microplastics were found in four out of five samples of penis tissue taken from five different men as part of a study published in IJIR: Your Sexual Medicine Journal on Wednesday. Microplastics are polymer fragments that can range from less than 0.2 inch (5 millimeters) down to 1/25,000th of an inch (1 micrometer). Anything smaller is a nanoplastic that must be measured in billionths of a meter. They form when larger plastics break down, either by chemically degrading or physically wearing down into smaller pieces.

Some minuscule particles can invade individual cells and tissues in major organs, experts say, and evidence is mounting that they are increasingly present in our bodies. Study lead author Ranjith Ramasamy, an expert in reproductive urology who conducted the research while working at the University of Miami, told CNN that he used a previous study that found evidence of microplastics in the human heart as a basis for his research. Ramasamy said he wasn't surprised to find microplastics in the penis, as it is a "very vascular organ," like the heart.

Astronomers are observing the sudden awakening of a giant black hole in the constellation of Virgo. "Decades of observations found nothing remarkable about the distant galaxy in the constellation of Virgo, but that changed at the end of 2019 when astronomers noticed a dramatic surge in its luminosity that persists to this day," reports The Guardian. "Researchers now believe they are witnessing changes that have never been seen before, with the black hole at the galaxy's core putting on an extreme cosmic light show as vast amounts of material fall into it." From the report: The galaxy, which goes by the snappy codename SDSS1335+0728 and lies 300m light years away, was flagged to astronomers in December 2019 when an observatory in California called the Zwicky Transient Facility recorded a sudden rise in its brightness. The alert prompted a flurry of new observations and checks of archived measurements from ground- and space-based telescopes to understand more about the galaxy and its past behavior.

The scientists discovered the galaxy had recently doubled in brightness in mid-infrared wavelengths, become four times brighter in the ultraviolet, and at least 10 times brighter in the X-ray range. What triggered the sudden brightening is unclear, but writing in Astronomy and Astrophysics, the researchers say the most likely explanation is the creation of an "active galactic nucleus" where a vast black hole at the centre of a galaxy starts actively consuming the material around it.

Active galactic nuclei emit a broad spectrum of light as gas around the black hole heats up and glows, and surrounding dust particles absorb some wavelengths and re-radiate others. But it is not the only possibility. The team has not ruled out an exotic form of "tidal disruption event," a highly restrained phrase to describe a star that is ripped apart after straying too close to a black hole. Tidal disruption events tend to be brief affairs, brightening a galaxy for no more than a few hundred days, but more measurements are needed to rule out the process.

Researchers have devised a way to extract energy from the photosynthesis process of algae, according to an announcement from Concordia University.

Suspended in a specialized solution, the algae forms part of a "micro photosynthetic power cell" that can actually generate enough energy to power low-power devices like Internet of Things (IoT) sensors. "Photosynthesis produces oxygen and electrons. Our model traps the electrons, which allows us to generate electricity," [says Kirankumar Kuruvinashetti, PhD 20, now a Mitacs postdoctoral associate at the University of Calgary.] "So more than being a zero-emission technology, it's a negative carbon emission technology: it absorbs carbon dioxide from the atmosphere and gives you a current. Its only byproduct is water."

[...] Muthukumaran Packirisamy, professor in the Department of Mechanical, Industrial and Aerospace Engineering and the paper's corresponding author, admits the system is not yet able to compete in power generation with others like photovoltaic cells. The maximum possible terminal voltage of a single micro photosynthetic power cell is only 1.0V. But he believes that, with enough research and development, including artificial intelligence-assisted integration technologies, this technology has the potential to be a viable, affordable and clean power source in the future.

It also offers significant manufacturing advantages over other systems, he says. "Our system does not use any of the hazardous gases or microfibres needed for the silicon fabrication technology that photovoltaic cells rely on. Furthermore, disposing of silicon computer chips is not easy. We use biocompatible polymers, so the whole system is easily decomposable and very cheap to manufacture."
In the paper the researchers also described it as a âoemicrobial fuel cellâ...

"At the height of the COVID-19 pandemic, the U.S. military launched a secret campaign to counter what it perceived as China's growing influence in the Philippines..." reports Reuters.

"It aimed to sow doubt about the safety and efficacy of vaccines and other life-saving aid that was being supplied by China, a Reuters investigation found."

Reuters interviewed "more than two dozen current and former U.S officials, military contractors, social media analysts and academic researchers," and also reviewed posts on social media, technical data and documents about "a set of fake social media accounts used by the U.S. military" — some active for more than five years. Friday they reported the results of their investigation: Through phony internet accounts meant to impersonate Filipinos, the military's propaganda efforts morphed into an anti-vax campaign. Social media posts decried the quality of face masks, test kits and the first vaccine that would become available in the Philippines — China's Sinovac inoculation. Reuters identified at least 300 accounts on X, formerly Twitter, that matched descriptions shared by former U.S. military officials familiar with the Philippines operation. Almost all were created in the summer of 2020 and centered on the slogan #Chinaangvirus — Tagalog for China is the virus.

"COVID came from China and the VACCINE also came from China, don't trust China!" one typical tweet from July 2020 read in Tagalog. The words were next to a photo of a syringe beside a Chinese flag and a soaring chart of infections. Another post read: "From China — PPE, Face Mask, Vaccine: FAKE. But the Coronavirus is real." After Reuters asked X about the accounts, the social media company removed the profiles, determining they were part of a coordinated bot campaign based on activity patterns and internal data.

The U.S. military's anti-vax effort began in the spring of 2020 and expanded beyond Southeast Asia before it was terminated in mid-2021, Reuters determined. Tailoring the propaganda campaign to local audiences across Central Asia and the Middle East, the Pentagon used a combination of fake social media accounts on multiple platforms to spread fear of China's vaccines among Muslims at a time when the virus was killing tens of thousands of people each day. A key part of the strategy: amplify the disputed contention that, because vaccines sometimes contain pork gelatin, China's shots could be considered forbidden under Islamic law...

A senior Defense Department official acknowledged the U.S. military engaged in secret propaganda to disparage China's vaccine in the developing world, but the official declined to provide details. A Pentagon spokeswoman... also noted that China had started a "disinformation campaign to falsely blame the United States for the spread of COVID-19."
A senior U.S. military officer directly involved in the campaign told Reuters that "We didn't do a good job sharing vaccines with partners. So what was left to us was to throw shade on China's."

At least six senior State Department officials for the region objected, according to the article. But in 2019 U.S. Defense Secretary Mark Esper signed "a secret order" that "elevated the Pentagon's competition with China and Russia to the priority of active combat, enabling commanders to sidestep the StateDepartment when conducting psyops against those adversaries."

[A senior defense official] said the Pentagon has rescinded parts of Esper's 2019 order that allowed military commanders to bypass the approval of U.S. ambassadors when waging psychological operations. The rules now mandate that military commanders work closely with U.S. diplomats in the country where they seek to have an impact. The policy also restricts psychological operations aimed at "broad population messaging," such as those used to promote vaccine hesitancy during COVID...

Nevertheless, the Pentagon's clandestine propaganda efforts are set to continue. In an unclassified strategy document last year, top Pentagon generals wrote that the U.S. military could undermine adversaries such as China and Russia using "disinformation spread across social media, false narratives disguised as news, and similar subversive activities [to] weaken societal trust by undermining the foundations of government."

And in February, the contractor that worked on the anti-vax campaign — General Dynamics IT — won a $493 million contract. Its mission: to continue providing clandestine influence services for the military.

Bloomberg reports: A disease caused by a rare "flesh-eating bacteria" that can kill people within 48 hours is spreading in Japan after the country relaxed Covid-era restrictions. Cases of streptococcal toxic shock syndrome (STSS) reached 977 this year by June 2, higher than the record 941 cases reported for all of last year, according to the National Institute of Infectious Diseases, which has been tracking incidences of the disease since 1999.

Group A Streptococcus (GAS) typically causes swelling and sore throat in children known as "strep throat," but some types of the bacteria can lead to symptoms developing rapidly, including limb pain and swelling, fever, low blood pressure, that can be followed by necrosis, breathing problems, organ failure and death. People over 50 are more prone to the disease. "Most of the deaths happen within 48 hours," said Ken Kikuchi, a professor in infectious diseases at Tokyo Women's Medical University. "As soon as a patient notices swelling in foot in the morning, it can expand to the knee by noon, and they can die within 48 hours...."

At the current rate of infections, the number of cases in Japan could reach 2,500 this year, with a "terrifying" mortality rate of 30%, Kikuchi said.

Slashdot reader hackertourist shared this announcement from NASA's Jet Propulsion Laboratory: Edward C. Stone, former director of NASA's Jet Propulsion Laboratory and project scientist of the Voyager mission for 50 years, died on June 9, 2024. He was age 88...

Stone served on nine NASA missions as either principal investigator or a science instrument lead, and on five others as a co-investigator (a key science instrument team member). These roles primarily involved studying energetic ions from the Sun and cosmic rays from the galaxy. He had the distinction of being one of the few scientists involved with both the mission that has come closest to the Sun (NASA's Parker Solar Probe) and the one that has traveled farthest from it (Voyager).

Stone is best known for his work on NASA's longest-running mission, Voyager, whose twin spacecraft launched in 1977 and are still exploring deep space today. He served as Voyager's sole project scientist from 1972 until his retirement in 2022. Under Stone's leadership, the mission took advantage of a celestial alignment that occurs just once every 176 years to visit Jupiter, Saturn, Uranus, and Neptune. During their journeys, the spacecraft revealed the first active volcanoes beyond Earth, on Jupiter's moon Io, and an atmosphere rich with organic molecules on Saturn's moon Titan. Voyager 2 remains the only spacecraft to fly by Uranus and Neptune, revealing Uranus' unusual tipped magnetic poles, and the icy geysers erupting from Neptune's moon Triton.
The mission "transformed our understanding of the solar system, and is still providing useful data today," writes hackertourist. (Watch Stone speak in this 2018 video about the Voyager 2 spacecraft.) NASA's announcement also includes stories of Stone's desire to engage the public and his thoughtfulness in considering the true boundary of interstellar space. As director of JPL, Stone was responsible for more than two dozen other missions, including landing NASA's Pathfinder mission with the first Mars rover in 1996. "Ed Stone was a trailblazer who dared mighty things in space. He was a dear friend to all who knew him, and a cherished mentor to me personally," said Nicola Fox, associate administrator for the Science Mission Directorate at NASA Headquarters in Washington.

"Ed took humanity on a planetary tour of our solar system and beyond, sending NASA where no spacecraft had gone before. His legacy has left a tremendous and profound impact on NASA, the scientific community, and the world."

It's one of Saturn's 146 moons — just 310 miles in diameter (or 498 kilometers). Yet the European Space Agency plans to send a robot on a one-billion mile trip to visit it. Why?

Because astronomers have discovered Enceladus "possesses geysers that regularly erupt from its surface and spray water into space," reports the Guardian: Even more astonishing, these plumes contain complex organic compounds, including propane and ethane. "Enceladus has three key ingredients that are considered to be essential for the appearance of life," said astronomer Professor Michele Dougherty of Imperial College London. "It has got liquid water, organic material and a source of heat. That combination makes it my favourite moon in the whole solar system."
A panel of expert scientists have now recommended the Saturn moon for an ESA mission by 2040, according to the article, "with the aim of either landing on the moon or flying through the geysers spraying water and carbon chemicals from its surface into space. Preferably, both goals would be attempted, the panel added."

It will be tricky. Dougherty warns that Enceladus "is small with weak gravity, which means you will need a lot of fuel to slow it down so that it does not whiz past its target into deep space. That is going to be a tricky issue for those designing the mission." But Dougherty has a special interest, as the principal investigator for the magnetometer flown on the Cassini mission that studied Saturn and its moons between 2004 and 2017. "At one point, Cassini passed close to Enceladus and our instrument indicated Saturn's magnetic field was being dragged round the moon in a way that suggested the little moon had an atmosphere," said Dougherty. Cassini's managers agreed to direct the probe to take a closer look and, in July 2005, the spaceship swept over the moon's surface at a height of 173km — and detected significant amounts of water vapour. "It was wonderful," recalls Dougherty.

Subsequent sweeps produced even greater wonders. Huge geysers of water were pictured erupting from geological fault lines at the south pole. The only other body in the solar system, apart from Earth, possessing liquid water on its surface had been revealed. Finally came the discovery of organics in those plumes and Enceladus went from being rated a minor, unimportant moon to a world that is now set to trigger the expenditure of billions of euros and decades of effort by European astronomers and space engineers.

The $22 million paid by Change Healthcare's parent company to unlock its systems "may have emboldened bad actors to further target the vulnerable industry," writes Axios: There were 44 attacks against the health care sector in April, the most that [cybersecurity firm] Recorded Future has seen in the four years it's been collecting data. It was also the second-largest month-over-month jump, after 30 ransomware attacks were recorded in March. There were 32 attacks in February and May.
But an analysis by the security-focused magazine CSO says the "disastrous" incident also "starkly illustrated the fragility of the healthcare sector, prompting calls for regulatory action." In response to the attack, US politicians have called for mandated baseline cybersecurity standards in the health sector, as well as better information sharing. They have also raised concerns that industry consolidation is increasing cyber risk.
So what went wrong? The attackers used a set of stolen credentials to remotely access the company's systems. But the article also notes Change Healthcare's systems "suffered from a lack of segmentation, which enables easy lateral movement of the attack" — and that the company's acquisition may have played a role: Mergers and acquisitions create new cyber threats because they involve the integration of systems, data, and processes from different organizations, each with its own security protocols and potential vulnerabilities. "During this transition, cybercriminals can exploit discrepancies in security measures, gaps in IT governance, and the increased complexity of managing merged IT environments," Aron Brand, CTO of CTERA told CSOonline. "Additionally, the heightened sharing of sensitive information between parties provides more opportunities for data breaches."
And "In the end, paying the ransom failed to protect UHG from secondary attempts at extortion." In April, cybercriminals from the RansomHub group threatened to leak portions of 6TB of sensitive data stolen from the breach of Change Healthcare, and obtained through Nichy, according to an analysis by security vendor Forescout. An estimated one in three Americans had their sensitive data exposed as a result of the attack. Such secondary scams are becoming increasingly commonplace and healthcare providers are particularly at risk, according to compliance experts... The US Department of Health and Human Services (HHS) is investigating whether a breach of protected health information occurred in assessing whether either UHG or Change Healthcare violated strict healthcare sector privacy regulations.

Have scientists discovered infrared radiation, evidence of waste heat generated by the energy-harvesting star-surrounding spheres first proposed by British American physicist Freeman Dyson? CNN reports: [A] new study that looked at 5 million stars in the Milky Way galaxy suggests that seven candidates could potentially be hosting Dyson spheres — a finding that's attracting scrutiny and alternate theories... Using historical data from telescopes that pick up infrared signatures, the research team looked at stars located within less than 1,000 light-years from Earth: "We started with a sample of 5 million stars, and we applied filters to try to get rid of as much data contamination as possible," said lead study author Matías Suazo, a doctoral student in the department of physics and astronomy of Uppsala University in Sweden. "So far, we have seven sources that we know are glowing in the infrared but we don't know why, so they stand out...."

Among the natural causes that could explain the infrared glow are an unlucky alignment in the observation, with a galaxy in the background overlapping with the star, planetary collisions creating debris, or the fact that the stars may be young and therefore still surrounded by disks of hot debris from which planets would later form...

An earlier study, published in March and using data from the same sources as the new report, had also found infrared anomalies among a sample dataset of 5 million stars in our galaxy. "We got 53 candidates for anomalies that cannot be well explained, but can't say that all of them are Dyson sphere candidates, because that's not what we are specifically looking for," said Gabriella Contardo, a postdoctoral research fellow at the International School for Advanced Studies in Trieste, Italy, who led the earlier study. She added that she plans to check the candidates against Suazo's model to see how many tie into it. "You need to eliminate all other hypotheses and explanations before saying that they could be a Dyson sphere," she added. "To do so you need to also rule out that it's not some kind of debris disk, or some kind of planetary collision, and that also pushes the science forward in other fields of astronomy — so it's a win-win."

Both Contardo and Suazo agree that more research is needed on the data, and that ultimately they could turn to NASA's James Webb Space Telescope for more information, as it is powerful enough to observe the candidate stars directly. However, because of the lengthy, competitive procedures that regulate use of the telescope, securing access might take some time.

CNN adds that "A May 23 paper published in response to the one by Suazo and his colleagues suggests that at least three of the seven stars have been 'misidentified' as Dyson spheres and could instead be 'hot DOGs' — hot dust-obscured galaxies — and that the remaining four could probably be explained this way as well."

But "As for Dyson himself, if he were still alive, he also would be highly skeptical that these observations represent a technological signature, his son George argued: 'But the discovery of new, non-technological astronomical phenomena is exactly why he thought we should go out and look.' "

wgoodman shares a report from The Register: NASA's Voyager 1 spacecraft is back in action and conducting normal science operations for the first time since the veteran probe began spouting gibberish at the end of 2023. All four of the spacecraft's remaining operational instruments are now returning usable data to Earth, according to NASA. Some additional work is needed to tidy up the effects of the issue. Engineers need to resynchronize the timekeeping software of Voyager 1's three onboard computers to ensure that commands are executed at the correct times. Maintenance will also be performed on the digital tape recorder, which records some data from the plasma instrument for a six-monthly downlink to Earth.

Voyager 1's woes began in November 2023, when the spacecraft stopped transmitting usable data back to Earth. Rather than engineering and science data, NASA found itself faced with a repeating pattern of ones and zeroes, as though the spacecraft was somehow stalled. Engineers reckoned the issue lay with the Flight Data System (FDS) and in March sent a command -- dubbed a "poke" -- to get the FDS to try some other software sequences and thus circumvent whatever was causing the problem. The result was a complete memory dump from the computer, which allowed engineers to pinpoint where the corruption had occurred. It appeared that a single chip was malfunctioning, and engineers were faced with the challenge of devising a software update that would work around the defective hardware.

Usable engineering data began to be returned later in April, and in May the mission team sent commands to instruct the probe to keep science data flowing. The result was that the plasma wave subsystem and magnetometer instrument began sending data immediately. According to NASA, the cosmic ray subsystem and low energy charged particle instrument required a little more tweaking but are now operational. The rescue was made all the more impressive by the fact that it takes 22.5 hours for a command to reach Voyager 1 and another 22.5 hours for a response to be received on Earth.

The Pentagon announced the first winners of its $5.6 billion National Security Space Launch program, with Jeff Bezos' Blue Origin securing a spot for the first time alongside Elon Musk's SpaceX and United Launch Alliance (ULA). These companies will compete for contracts through mid-2029 under the program's Phase 3, which is expected to include 90 rocket launch orders. CNBC reports: Under the program, known as NSSL Phase 3 Lane 1, the trio of companies will be eligible to compete for contracts through mid-2029. ULA and SpaceX have already been competing for contracts under the previous Phase 2 edition of NSSL: In total, over five years of Phase 2 launch orders, the military assigned ULA with 26 missions worth $3.1 billion, while SpaceX got 22 missions worth $2.5 billion. Blue Origin, as well as Northrop Grumman, missed out on Phase 2 when the Pentagon selected ULA and SpaceX for the program in August 2020. But with Phase 3, the U.S. military is raising the stakes -- and widening the field -- on a high-profile competition for Space Force mission contracts. Phase 3 is expected to see 90 rocket launch orders in total, with a split approach of categories Lane 1 and Lane 2 to allow even more companies to bid.

Avian influenza outbreaks on US dairy farms have raised concerns about milk safety, leading some to consider alternatives like engineered milk proteins. Startups like Remilk and Alpine Bio are using yeast and soybeans to produce key milk proteins, aiming to replace dairy cows and reduce environmental impact. However, competing with subsidized dairy industries and their efficient use of cow byproducts remains a challenge for these biotech ventures, MIT Technology Review reports. The story adds: Everyone agrees that cow's milk will be difficult to displace. It holds a special place in the human psyche, and we owe civilization itself, in part, to domesticated animals. In fact, they've left their mark in our genes, with many of us carrying DNA mutations that make cow's milk easier to digest. But that's why it might be time for the next technological step, says Alpine's CEO Magi Richani. "We raise 60 billion animals for food every year, and that is insane. We took it too far, and we need options," she says. "We need options that are better for the environment, that overcome the use of antibiotics, and that overcome the disease risk." It's not clear yet whether the bird flu outbreak on dairy farms is a big danger to humans. But making milk without cows would definitely cut the risk that an animal virus will cause a new pandemic. As Richani says: "Soybeans don't transmit diseases to humans."
