Humanoid Robot Is the 'Fastest In the World' Thanks To Pair of Sneakers (livescience.com) 33

AmiMoJo shares a report from Live Science: Scientists have demonstrated a new humanoid robot that can run at a top speed of just over 8 miles per hour (mph) -- or 3.6 meters per second (m/s) to be exact. This makes it the speediest machine of its kind built so far, albeit these speeds were only achieved with the help of added footwear. STAR1 is a bipedal robot built by the Chinese company Robot Era that's 5 feet 7 inches (171 centimeters) tall and weighs 143 pounds (65 kilograms).

Powered by high-torque motors and artificial intelligence (AI) algorithms, the footwear-donning STAR1 navigated different types of terrain, including grassland and gravel, while jogging on paved roads and earth, and sustained its top speed for 34 minutes. A top speed of 8 mph means it beat Unitree's H1 robot -- which set the previous speed record for a bipedal robot at 7.4 mph (3.3 m/s) in March 2024. Although STAR1 had the help of footwear, H1 was not technically jogging or running as its feet did not both leave the ground at once during transit.

Dinosaur Fossils Found For First Time in Hong Kong 6

Hong Kong officials discovered the city's first dinosaur fossils on an uninhabited island in a local geopark, they said Wednesday. Initial examinations indicate the remains belong to a large Cretaceous-era dinosaur from 66-145 million years ago, with species identification pending further study. Associated Press adds: Experts speculate that the dinosaur was likely buried by sand and gravel after its death before it was later washed to the surface by a large flood, and subsequently buried again at the discovery site, it said.

Physicist Reveals Why You Should Run in The Rain (sciencealert.com) 116

Theoretical Physicist Jacques Treiner, from the University of Paris Cite, explains why you should run in the rain: ... Let p represent the number of drops per unit volume, and let a denote their vertical velocity. We'll denote Sh as the horizontal surface area of the individual (e.g., the head and shoulders) and Sv as the vertical surface area (e.g., the body). When you're standing still, the rain only falls on the horizontal surface, Sh. This is the amount of water you'll receive on these areas. Even if the rain falls vertically, from the perspective of a walker moving at speed v, it appears to fall obliquely, with the angle of the drops' trajectory depending on your speed. During a time period T, a raindrop travels a distance of aT. Therefore, all raindrops within a shorter distance will reach the surface: these are the drops inside a cylinder with a base of Sh and a height of aT, which gives:
p.Sh.a.T.

As we have seen, as we move forward, the drops appear to be animated by an oblique velocity that results from the composition of velocity a and velocity v. The number of drops reaching Sh remains unchanged, since velocity v is horizontal and therefore parallel to Sh. However, the number of drops reaching surface Sv -- which was previously zero when the walker was stationary -- has now increased. This is equal to the number of drops contained within a horizontal cylinder with a base area of Sv and a length of v.T. This length represents the horizontal distance the drops travel during this time interval. In total, the walker receives a number of drops given by the expression:
p.(Sh.a + Sv.v). T

Now we need to take into account the time interval during which the walker is exposed to the rain. If you're covering a distance d at constant speed v, the time you spend walking is d/v. Plugging this into the equation, the total amount of water you encounter is:
p.(Sh.a + Sv.v). d/v = p.(Sh.a/v + Sv). d
This equation proves that the faster you move, the less water hits your head and shoulders, but the amount of water hitting the vertical part of your body remains constant. To stay drier, it's best to move quickly and lean forward. However, you'll have to increase your speed to offset the exposed surface area caused by leaning.

NASA Reveals Prototype Telescope For Gravitational Wave Observatory (phys.org) 14

NASA has revealed a full-scale prototype for six telescopes designed to detect gravitational waves. Phys.Org reports: The LISA (Laser Interferometer Space Antenna) mission is led by ESA (European Space Agency) in partnership with NASA to detect gravitational waves by using lasers to measure precise distances -- down to picometers, or trillionths of a meter -- between a trio of spacecraft distributed in a vast configuration larger than the sun. Each side of the triangular array will measure nearly 1.6 million miles, or 2.5 million kilometers.

The Engineering Development Unit Telescope, which was manufactured and assembled by L3Harris Technologies in Rochester, New York, arrived at Goddard in May. The primary mirror is coated in gold to better reflect the infrared lasers and to reduce heat loss from a surface exposed to cold space, since the telescope will operate best when close to room temperature.

The prototype is made entirely from an amber-colored glass-ceramic called Zerodur, manufactured by Schott in Mainz, Germany. The material is widely used for telescope mirrors and other applications requiring high precision because its shape changes very little over a wide range of temperatures. The LISA mission is slated to launch in the mid-2030s.

'Electric Plastic' Could Unleash Next-Gen Implants and Wearable Tech (science.org) 38

An anonymous reader quotes a report from Science Magazine: Imagine a thin wristband that monitors your steps and heartbeat like an Apple Watch. Or clothing that keeps you cool with built-in air conditioning. Or even a flexible implant that could help your heart better than a bulky pacemaker. That's the promise of a new, electrically active material researchers have created by combining short chains of amino acids called peptides with snippets of a polymer plastic. This "electric plastic," reported this month in Nature, can store energy or record information, opening the door to self-powered wearables, real-time neural interfaces, and medical implants that merge with bodies better than current tech. [...]

Samuel Stupp, a materials scientist at Northwestern University, and his colleagues thought they could improve on polyvinylidene fluoride's (PVDF) properties. The team connected peptides with small PVDF segments, which naturally assembled into long, flexible ribbons. The molecules then coalesced into bundles and aligned to form an electro-active material. "Remarkably," Stupp says, "the self-assembly process is triggered by adding water." The new material overcomes PVDF's limitations. It requires 100 times less voltage to switch polarization compared with other ferroelectric materials, making it ideal for low-power applications. And it retains its ferroelectric properties at temperatures of 110C -- about 40C higher than other PVDF materials.

Stupp's new material can store energy or information by electrically switching the polarity of each ribbon. And because the peptide on the end of each ribbon can be connected to proteins on neurons or other cells, the molecules can record the signals from the brain, heart, or other organs -- or electrically stimulate them. By using low-power techniques like ultrasound to "charge" the molecules, the material could be used to stimulate neurons as a treatment for chronic paralysis, Stupp says. Study co-author Yang Yang, an electrical power engineer at Northwestern, notes that PVDF is biocompatible, making the material a promising candidate for soft implants that could be wirelessly controlled from outside the body.
Stupp's team has conducted small-scale evaluations of molecules, but scaling up will require placing water-suspended structures onto devices without altering them -- a challenge noted by chemist Frank Leibfarth. Even with this hurdle, "This advance has enabled a number of attractive properties compared to other organic polymers," he says.

Stupp added: "This paper has a much broader concept than just vinylidene fluoride. There probably are other possibilities ... that don't have fluorine."

Comic Sans Got the Last Laugh 57

On July 4, 2012, CERN physicist Fabiola Gianotti announced a major quantum field theory discovery using a PowerPoint presentation in Comic Sans, sparking both mockery and debate. The font, created by Vincent Connare for Microsoft Bob in 1994, featured deliberately imperfect letters inspired by comic books. Comic Sans shipped with Windows 95 and exploded in popularity as personal computing democratized typography. A backlash emerged as the font appeared on everything from funeral notices to museum signs, culminating in Dave and Holly Combs's "Ban Comic Sans" campaign.

'Operating in the Stone Age': NHS Staff's Daily Struggle With Outdated Tech 113

The Financial Times: In the paediatric centre at one of London's largest hospitals, doctors are confounded each day by a ward computer that is not connected to a printer. The computer is used for managing the daily list of patients. Doctors can only access and update the list, using one shared account. So twice a day, two doctors on the ward said one of them had to log in to this computer, update the patient list, send the list to themselves via NHS email, and then log in to another nearby computer to print it off for the team. "I am at a top London hospital and yet at times I feel as though we are operating in the Stone Age," said one paediatrician on the ward.

Tackling the frustrating delays caused by outdated technology [Editor's note: non-paywalled link] is one of health secretary Wes Streeting and Prime Minister Sir Keir Starmer's core missions, having vowed to shift the service "from an analogue to a digital NHS." The monumental task of moving the world's largest publicly funded health service into the digital age is not lost on doctors working on the frontline of the NHS. While many sectors of the economy have been "radically reshaped" by technology in recent years, a landmark report into the state of the health service in England last month concluded that the NHS stood "in the foothills of digital transformation."

But doctors and nurses point out that the basic infrastructure needs to be brought up to a minimum standard, given significant regional variations between hospitals, before politicians extol the virtues of cutting-edge tech. "Some of us just want the printers to work," noted one NHS hospital doctor. "The complete flip-a-coin nature of how equipped your hospital is is mind-boggling," they added. "I have worked in hospitals that are at least 12 years behind others." A report published in 2022 by the British Medical Association, the UK's main doctors' union, estimated that doctors in England lost 13.5mn working hours a year as a consequence of "inadequate IT systems and equipment." One reason for the outdated infrastructure is that the country has spent almost $48bn less than its peers -- such as Germany, France, Australia -- on health assets since the 2010s, according to a government-commissioned study by Lord Ara Darzi last month.

NASA Further Delays First Operational Starliner Flight (spacenews.com) 33

NASA will rely on SpaceX's Crew Dragon for two crewed missions to the ISS in 2025 while evaluating whether Boeing's Starliner requires another test flight for certification. SpaceNews reports: In an Oct. 15 statement, NASA said it will use Crew Dragon for both the Crew-10 mission to the ISS, scheduled for no earlier than February 2025, and the Crew-11 mission scheduled for no earlier than July. Crew-10 will fly NASA astronauts Anne McClain and Nichole Ayers along with astronaut Takuya Onishi from the Japanese space agency JAXA and Roscosmos cosmonaut Kirill Peskov. NASA has not yet announced the crew for the Crew-11 mission.

Earlier this year, NASA had hoped that Boeing's CST-100 Starliner would be certified in time to fly the early 2025 mission. Problems with the Crew Flight Test mission, which launched in June with NASA astronauts Butch Wilmore and Suni Williams on board, led NASA to conclude in July that the spacecraft would not be certified in time. It delayed that Starliner-1 mission from February to August 2025, moving up Crew-10 to February. NASA also announced then that it would prepare Crew-11 in parallel with Starliner-1 for launch in that August 2025 slot.
"The timing and configuration of Starliner's next flight will be determined once a better understanding of Boeing's path to system certification is established," NASA said in its statement about the 2025 missions. "NASA is keeping options on the table for how best to achieve system certification, including windows of opportunity for a potential Starliner flight in 2025."

A Calculator's Most Important Button Has Been Removed (theatlantic.com) 108

Apple's latest iOS update has removed the "C" button from its Calculator app, replacing it with a backspace function. The change, part of iOS 18, has sparked debate among users accustomed to the traditional clear function. The removal of the "C" button represents a significant departure from decades-old calculator design conventions, The Atlantic writes. From the story: The "C" button's function is vestigial. Back when calculators were commercialized, starting in the mid-1960s, their electronics were designed to operate as efficiently as possible. If you opened up a desktop calculator in 1967, you might have found a dozen individual circuit boards to run and display its four basic mathematical functions. Among these would have been an input buffer or temporary register that could store an input value for calculation and display. The "C" button, which was sometimes labeled "CE" (Clear Entry) or "CI" (Clear Input), provided a direct interface to zero out -- or "clear" -- such a register. A second button, "AC" (All Clear), did the same thing, but for other parts of the circuit, including previously stored operations and pending calculations. (A traditional calculator's memory buttons -- "M+," "M-," "MC" -- would perform simple operations on a register.)

By 1971, Mostech and Texas Instruments had developed a "calculator on a chip," which condensed all of that into a single integrated circuit. Those chips retained the functions of their predecessors, including the ones that were engaged by "C" and "AC" buttons. And this design continued on into the era of pocket calculators, financial calculators, and even scientific calculators such as the ones you may have used in school. Some of the latter were, in essence, programmable pocket computers themselves, and they could have been configured with a backspace key. They were not.

Egypt Declared Malaria-Free After Century of Work To Defeat Disease (semafor.com) 36

Egypt was declared malaria-free by the World Health Organization, after nearly a century of work to eradicate the disease in the country. From a report: Egypt saw 3 million cases a year in the 1940s, and the Aswan Dam's development in the 1960s created new bodies of standing water for the mosquitoes to breed in, but by 2001 the disease was "firmly under control," according to the WHO. "The disease that plagued pharaohs now belongs to [Egypt's] history," the WHO's chief said. It's the 44th country to be certified, but the wider battle against malaria goes on: The mosquito-borne disease still kills around 600,000 people a year, the large majority of them children in sub-Saharan Africa.

NASA's Artemis Mission To Moon Unveils New Spacesuit Designed By Prada (spacenews.com) 51

For the first time in 50 years, humans will walk on the moon again. Currently planned for as soon as 2026, the Artemis III mission "will be one of the most complex undertakings of engineering and human ingenuity in the history of deep space exploration..." writes NASA. "Two crew members will descend to the surface and spend approximately a week near the South Pole of the Moon conducting new science before returning to lunar orbit..."

And they'll be wearing Prada, according to a Space News report from Milan: At a briefing at the International Astronautical Congress here October 16, Axiom and Prada revealed details about the Axiom Extravehicular Mobility Unit (AxEMU) suit that Axiom is creating for use by NASA on lunar landing missions starting with Artemis 3... Axiom emphasized the advanced capabilities in the suit, particularly when compared to the suits worn by the Apollo astronauts on moonwalks more than a half-century ago [including greater redundancy and healthy monitoring systems not available in Apollo-era suits]...

The unveiling came just over a year after Axiom announced it was working with luxury goods company Prada, an unconventional partnership intended to leverage Prada's expertise in materials and design... [Axiom's executive VP of extravehicular activity Russell Ralston] said Axiom has leveraged Prada's expertise in fabrics and garment design in helping create the outer layer of the suit, which reflects sunlight and keeps dust from getting into interior layers... "If you look across all the different technologies that are needed within the suit, the uniqueness of those technologies and their application, the supply chain has tended to be pretty unstable," he said. "So, one of the things that Prada has really helped us with is bringing stability to that base, especially on the fabric side...."

Not surprisingly, Prada also contributed to the appearance of the suit. "One of the things that was important to us was the appeal of the suit, the look of the suit," Ralston said. "Something that Prada brought to the table was helping with the general aesthetic of the suit." One design aspect that brought the two companies together was a prominent red stripe on the suit. Ralston noted that was a nod to a NASA tradition where the mission commander's suit would have that red stripe to distinguish them from another spacewalker...

While the current focus of the suit is for walking on the moon, Ralston said the suit can be easily adapted for applications in low Earth orbit, such as spacewalks from the International Space Station or Axiom's future commercial space station.

The article adds that 30 people worked on the suit (full- or part-time). "These suits will give the astronauts increased range of motion and flexibility to explore more of the landscape than on previous lunar missions," according to NASA.

With "the ability to send high quality images and video to the ground with advanced communication technology, they will be sharing a unique new human experience with the world."

Electric Motors Are About to Get a Major Upgrade - Thanks to Benjamin Franklin (msn.com) 70

"A technology pioneered by Benjamin Franklin is being revived to build more efficient electric motors," reports the Wall Street Journal, "an effort in its nascent stage that has the potential to be massive." A handful of scientists and engineers — armed with materials and techniques unimaginable in the 1700s — are creating modern versions of Franklin's "electrostatic motor," that are on the cusp of commercialization... Franklin's "electrostatic motor" uses alternating positive and negative charges — the same kind that make your socks stick together after they come out of the dryer — to spin an axle, and doesn't rely on a flow of current like conventional electric motors. Every few years, an eager Ph.D. student or engineer rediscovers this historical curiosity. But other than applications in tiny pumps and actuators etched on microchips, where this technology has been in use for decades, their work hasn't made it out of the lab.

Electrostatic motors have several potentially huge advantages over regular motors. They are up to 80% more efficient than conventional motors after all the dependencies of regular electric motors are added in. They could also allow new kinds of control and precision in robots, where they could function more like our muscles. And they don't use rare-earth elements because they don't have permanent magnets, and require as little as 5% as much copper as a conventional motor. Both materials have become increasingly scarce and expensive over the past decade, and supply chains for them are dominated by China.

"It's reminiscent of the early 1990s, when Sony began to produce and sell the first rechargeable lithium-ion batteries, a breakthrough that's now ubiquitous..." according to the article. "These motors could lead to more efficient air-conditioning systems, factories, logistics hubs and data centers, and — since they can double as generators — better ways of generating renewable energy. They might even show up in tiny surveillance drones."

And the article points out that C-Motive Technologies, a 16-person startup in Wisconsin, is already "reaching out to companies, hoping to get their motors out into the real world." ("So far, FedEx and Rockwell Automation, the century-old supplier of automation to factories, are among those testing their motors.") C-Motive's founders discovered that a number of technologies had matured enough that, when combined, could yield electrostatic motors competitive with conventional ones. These enabling technologies include super fast-switching power electronics — like those in modern electric vehicles — that can toggle elements of the motor between states of positive and negative charge very quickly... Dogged exploration of combinations of various readily available industrial organic fluids led to a proprietary mix that can both multiply the strength of the electric field and insulate the motor's spinning parts from each other — all without adding too much friction — says C-Motive Chief Executive Matt Maroon.

MIT Researchers Build Solar-Powered Low-Cost Drinking Water Desalination System (mit.edu) 54

MIT engineers have built a solar-powered desalination system that "ramps up its desalting process and automatically adjusts to any sudden variation in sunlight, for example by dialing down in response to a passing cloud or revving up as the skies clear."

While traditional reverse osmosis systems typically require steady power levels, "the MIT system requires no extra batteries for energy storage, nor a supplemental power supply, such as from the grid." And their results were pretty impressive: The engineers tested a community-scale prototype on groundwater wells in New Mexico over six months, working in variable weather conditions and water types. The system harnessed on average over 94 percent of the electrical energy generated from the system's solar panels to produce up to 5,000 liters of water per day despite large swings in weather and available sunlight... "Being able to make drinking water with renewables, without requiring battery storage, is a massive grand challenge," says Amos Winter, the Germeshausen Professor of Mechanical Engineering and director of the K. Lisa Yang Global Engineering and Research Center at MIT. "And we've done it."

The system is geared toward desalinating brackish groundwater — a salty source of water that is found in underground reservoirs and is more prevalent than fresh groundwater resources. The researchers see brackish groundwater as a huge untapped source of potential drinking water, particularly as reserves of fresh water are stressed in parts of the world. They envision that the new renewable, battery-free system could provide much-needed drinking water at low costs, especially for inland communities where access to seawater and grid power are limited...

The researchers' report details the new system in a paper appearing in Nature Water. The study's co-authors are Bessette, Winter, and staff engineer Shane Pratt... "Our focus now is on testing, maximizing reliability, and building out a product line that can provide desalinated water using renewables to multiple markets around the world," Pratt adds. The team will be launching a company based on their technology in the coming months.

This research was supported in part by the National Science Foundation, the Julia Burke Foundation, and the MIT Morningside Academy of Design. This work was additionally supported in-kind by Veolia Water Technologies and Solutions and Xylem Goulds.

Serious Infections Linked to Dementia Risk, Study Shows (msn.com) 18

"Getting sick feels bad in the moment," reports the Washington Post, "and may affect your brain in the longer term." A new study published in Nature Aging adds to growing evidence that severe infections, including flu, herpes and respiratory tract infections, are linked to accelerated brain atrophy and increased risk of dementia years later. It also hints at the biological drivers that may contribute to neurodegenerative disease.

The current research is a "leap beyond previous studies that had already associated infection with susceptibility to Alzheimer's disease" and provides a "useful dataset," said Rudy Tanzi, a professor of neurology at Harvard Medical School and the director of the McCance Center for Brain Health at Massachusetts General Hospital. Other recent studies have found that the flu shot and the shingles vaccine reduce the risk of subsequent dementia in those who get them. Severe infections have also been linked to subsequent strokes and heart attacks.

"Big infection, big immune response — not good for the brain," said one of the study's co-authors (Keenan Walker, a tenure-track investigator and the director of the Multimodal Imaging of Neurodegenerative Disease Unit at the National Institute on Aging).

And the article also includes this quote from Kristen Funk, an assistant professor of biological sciences at the University of North Carolina at Charlotte (who studies neuroinflammation in neuroinfectious and neurodegenerative diseases). "They really found that there's a range of infections that are associated with this brain atrophy, associated with this cognitive decline." In turn, most of these infections associated with brain atrophy seem to be risk factors for dementia, according to the researchers' analyses of the UK Biobank data of 495,896 subjects and a Finnish dataset of 273,132 subjects. They found that having a history of infections was associated with an increased risk for Alzheimer's disease years later. The increased risk was even higher for vascular dementia, which is the second-most-common dementia diagnosis after Alzheimer's disease and caused by restriction of blood to the brain...

More-minor infections are not cause for alarm since the data was drawn from patients who had a hospital record of their infections, indicating more-severe cases, experts say.

And speaking of infections, the Post also published an interesting guest column by Dr. Mikkael A. Sekeres, division chief for hematology and medicine professor at the University of Miami's cancer center: A recent report from the American Association for Cancer Research attributed 13 percent of cancer cases worldwide to infections. Some estimates run as high as 20 percent, with particularly high rates of infection-related cancers in developing countries. Infectious agents linked to cancer include bacteria, such as Helicobacter pylori (H. pylori), and viruses, such as human papillomavirus (HPV), Epstein-Barr virus (EBV), and hepatitis B and C.

But keep in mind that an exceedingly small percentage of infected people develop cancer...

'NASA's $100 Billion Moon Mission Is Going Nowhere' (bloomberg.com) 94

Longtime Slashdot reader schwit1 shares an op-ed written by Michael R. Bloomberg, founder and majority owner of Bloomberg LP, the parent company of Bloomberg News, UN Special Envoy on Climate Ambition and Solutions, and chair of the Defense Innovation Board: There are government boondoggles, and then there's NASA's Artemis program. More than a half century after Neil Armstrong's giant leap for mankind, Artemis was intended to land astronauts back on the moon. It has so far spent nearly $100 billion without anyone getting off the ground, yet its complexity and outrageous waste are still spiraling upward. The next US president should rethink the program in its entirety. As someone who greatly respects science and strongly supports space exploration, the more I have learned about Artemis, the more it has become apparent that it is a colossal waste of taxpayer money. [...]

A celestial irony is that none of this is necessary. A reusable SpaceX Starship will very likely be able to carry cargo and robots directly to the moon -- no SLS, Orion, Gateway, Block 1B or ML-2 required -- at a small fraction of the cost. Its successful landing of the Starship booster was a breakthrough that demonstrated how far beyond NASA it is moving. Meanwhile, NASA is canceling or postponing promising scientific programs -- including the Veritas mission to Venus; the Viper lunar rover; and the NEO Surveyor telescope, intended to scan the solar system for hazardous asteroids -- as Artemis consumes ever more of its budget. Taxpayers and Congress should be asking: What on Earth are we doing? And the next president should be held accountable for answers.

Diamond Dust Could Cool the Planet At a Cost of Mere Trillions (science.org) 98

sciencehabit shares a report from Science Magazine: From dumping iron into the ocean to launching mirrors into space, proposals to cool the planet through 'geoengineering' tend to be controversial -- and sometimes fantastical. A new idea isn't any less far-out, but it may avoid some of the usual pitfalls of strategies to fill the atmosphere with tiny, reflective particles. In a modeling study published this month in Geophysical Research Letters, scientists report that shooting 5 million tons of diamond dust into the stratosphere each year could cool the planet by 1.6C -- enough to stave off the worst consequences of global warming. The scheme wouldn't be cheap, however: experts estimate it would cost nearly $200 trillion over the remainder of this century -- far more than traditional proposals to use sulfur particles. [...]

The researchers modeled the effects of seven compounds, including sulfur dioxide, as well as particles of diamond, aluminum, and calcite, the primary ingredient in limestone. They evaluated the effects of each particle across 45 years in the model, where each trial took more than a week in real-time on a supercomputer. The results showed diamond particles were best at reflecting radiation while also staying aloft and avoiding clumping. Diamond is also thought to be chemically inert, meaning it would not react to form acid rain, like sulfur. To achieve 1.6C of cooling, 5 million tons of diamond particles would need to be injected into the stratosphere each year. Such a large quantity would require a huge ramp up in synthetic diamond production before high-altitude aircraft could sprinkle the ground-up gems across the stratosphere. At roughly $500,000 per ton, synthetic diamond dust would be 2,400 times more expensive than sulfur and cost $175 trillion if deployed from 2035 to 2100, one study estimates.

SpaceX Secures New Contracts Worth $733.5 Million For National Security Space Missions (spacenews.com) 39

An anonymous reader quotes a report from Space News: SpaceX has been awarded contracts for eight launches under the National Security Space Launch (NSSL) Phase 3 Lane 1 program, the U.S. Space Force's Space Systems Command announced Oct. 18. The contracts worth $733.5 million span seven missions for the Space Development Agency (SDA) and one for the National Reconnaissance Office (NRO) projected to launch in 2026. These are part of the NSSL Phase 3 procurement of launch services for U.S. defense and intelligence agencies.

The NSSL Phase 3 Lane 1 program is structured as an Indefinite Delivery, Indefinite Quantity (IDIQ) contract, a flexible procurement method often used in government contracting. The total value of the Lane 1 contract is estimated at $5.6 billion over five years, with Blue Origin, SpaceX, and United Launch Alliance (ULA) selected as the primary vendors to compete for individual task orders. The Space Development Agency is utilizing SpaceX's Falcon 9 rocket to launch small satellites into a low-Earth orbit (LEO) constellation, a network of satellites designed to enhance military communications and intelligence capabilities. SpaceX has already completed two successful launches for the Tranche 0 portion of SDA's constellation.

"The Phase 3 Lane 1 construct allows us to execute launch services more quickly for risk-tolerant payloads, putting more capabilities in orbit faster to support national security," said Brig. Gen. Kristin Panzenhagen, program executive officer for Assured Access to Space at the Space Force. Blue Origin's New Glenn rocket has yet to perform its first launch and will need to complete at least two successful flights to qualify for NSSL certification, while ULA's Vulcan Centaur, which has completed two flights, is still awaiting final certification for the program.

US Startup Charging Couples To 'Screen Embryos For IQ' 130

An anonymous reader quotes a report from The Guardian: A US startup company is offering to help wealthy couples screen their embryos for IQ using controversial technology that raises questions about the ethics of genetic enhancement. The company, Heliospect Genomics, has worked with more than a dozen couples undergoing IVF, according to undercover video footage. The recordings show the company marketing its services at up to $50,000 for clients seeking to test 100 embryos, and claiming to have helped some parents select future children based on genetic predictions of intelligence. Managers boasted their methods could produce a gain of more than six IQ points. [...]

The footage appears to show experimental genetic selection techniques being advertised to prospective parents. A Heliospect employee, who has been helping the company recruit clients, outlined how couples could rank up to 100 embryos based on "IQ and the other naughty traits that everybody wants," including sex, height, risk of obesity and risk of mental illness. The startup says its prediction tools were built using data provided by UK Biobank, a taxpayer-funded store of genetic material donated by half a million British volunteers, which aims to only share data for projects that are "in the public interest".

Selecting embryos on the basis of predicted high IQ is not permitted under UK law. While it is legal in the US, where embryology is more loosely regulated, IQ screening is not yet commercially available there. Asked for comment, managers at Heliospect said the company, which is incorporated in the US, operated within all applicable law and regulations. They said Heliospect was in "stealth mode" before a planned public launch and was still developing its service. They added that clients who screened fewer embryos were charged about $4,000, and that pricing on launch would be in line with competitors. Leading geneticists and bioethicists said the project raised a host of moral and medical issues.

All Mobile Phones Must Be Hearing Aid Compatible Under New FCC Rules (techcrunch.com) 17

In a press release today, the FCC said it is requiring all mobile phones sold in the U.S. to be compatible with hearing aids. TechCrunch reports: The FCC has not yet issued a specific timeline for compliance, only noting that the rules will be fully in effect "after a transition period." The rules discourage handset makers from instituting proprietary Bluetooth coupling, which could limit device compatibility with over-the-counter hearing aids. Under the new rules, companies will be required to note on their website if a given handset is compatible with hearing aids. Two years ago, the FDA announced that hearing aids would no longer require a prescription. The agency also recently approved Apple AirPods as hearing aids.
