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 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.

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."

A judge has allowed Saudi dissident Yahya Assiri to sue the kingdom for allegedly targeting his devices with Pegasus spyware and other Israeli-made surveillance tools. Reuters reports: Yahya Assiri, a founder of the opposition National Assembly Party (NAAS) who lives in exile in Britain, alleges his electronic devices were targeted with surveillance software between 2018 and 2020. He is suing Saudi Arabia at London's High Court, saying the country used Pegasus - made by Israeli company NSO Group and sold only to nation states - and other spyware made by lesser-known Israeli firm QuaDream because of his work with dissidents. Earlier this month, Roger Eastman, a judge in the High Court, gave Assiri permission to serve his lawsuit on the Saudi government, a step that required the court to find Assiri has an arguable case. The decision announced on Monday to allow the case to be served on Saudi Arabia in Riyadh was made on Oct. 11. Assiri said in a statement: "I am fully aware that the authorities will want to target me. However, it is outrageous for them also to target individuals such as the victims of rights abuses and their families in Saudi Arabia simply because these people have been in contact with me."

San Francisco's Municipal Transportation Agency approved a $212 million contract with Hitachi Rail to modernize the Muni Metro system's outdated train control system, which currently uses floppy disks and wire loops. Government Technology reports: The software that runs the system is stored on floppy disks that are loaded each morning and an outdated type of communication using wire loops that are easily disrupted. It was expected to last for 20 to 25 years, according to Muni officials. It moves data more slowly than a wireless modem, they said. By late 2027 and into 2028, a new communications-based system, which employs Wi-Fi and cell signals to precisely track the locations of trains, will be installed by Hitachi, which will provide support services for 20 years under the agreement. While the current train control system operates only on the Market Street subway and Central Subway, the new system will control Metro light rail trains on the system's surface lines as well. The Hitachi system is said to be five generations ahead of the current system, said Muni Director of Transit Julie Kirschbaum, who described it as the best train control system on the market.

A civil liberties group has filed a lawsuit in Virginia arguing that the widespread use of Flock's automated license plate readers violates the Fourth Amendment's protections against warrantless searches. 404 Media reports: "The City of Norfolk, Virginia, has installed a network of cameras that make it functionally impossible for people to drive anywhere without having their movements tracked, photographed, and stored in an AI-assisted database that enables the warrantless surveillance of their every move. This civil rights lawsuit seeks to end this dragnet surveillance program," the lawsuit notes (PDF). "In Norfolk, no one can escape the government's 172 unblinking eyes," it continues, referring to the 172 Flock cameras currently operational in Norfolk. The Fourth Amendment protects against unreasonable searches and seizures and has been ruled in many cases to protect against warrantless government surveillance, and the lawsuit specifically says Norfolk's installation violates that. [...] The lawsuit in Norfolk is being filed by the Institute for Justice, a civil liberties organization that has filed a series of privacy and government overreach lawsuits over the last few years. Two Virginia residents, Lee Schmidt and Crystal Arrington, are listed as plaintiffs in the case. Schmidt is a Navy veteran who alleges in the lawsuit that the cops can easily infer where he is going based on Flock data. "Just outside his neighborhood, there are four Flock Cameras. Lee drives by these cameras (and others he sees around town) nearly every day, and the Norfolk Police Department [NPD] can use the information they record to build a picture of his daily habits and routines," the lawsuit reads. "If the Flock Cameras record Lee going straight through the intersection outside his neighborhood, for example, the NPD can infer that he is going to his daughter's school. If the cameras capture him turning right, the NPD can infer that he is going to the shooting range. If the cameras capture him turning left, the NPD can infer that he is going to the grocery store. The Flock Cameras capture the start of nearly every trip Lee makes in his car, so he effectively cannot leave his neighborhood without the NPD knowing about it." Arrington is a healthcare worker who makes home visits to clients in Norfolk. The lawsuit alleges that it would be trivial for the government to identify her clients. "Fourth Amendment case law overwhelmingly shows that license plate readers do not constitute a warrantless search because they take photos of cars in public and cannot continuously track the movements of any individual," a Flock spokesperson said. "Appellate and federal district courts in at least fourteen states have upheld the use of evidence from license plate readers as Constitutional without requiring a warrant, as well as the 9th and 11th circuits. Since the Bell case, four judges in Virginia have ruled the opposite way -- that ALPR evidence is admissible in court without a warrant."
