TECHCRUNCH.COMGirls Who Code founder Reshma Saujani spills business tea with Meghan, Duchess of SussexReshma Saujani, founder of the non-profit Girls Who Code, got straight to the point. “If I had applied to be the CEO of Girls Who Code, I wouldn’t have gotten the job,” she told Meghan, Duchess of Sussex, on the latest episode of the duchess’ podcast, “Confessions of a Female Founder.” “I didn’t code,” Saujani continued. “I majored in polyscience, speech communications, and the only thing I’d ever built was a failed [congressional] campaign,” she said, referring to when she tried running for Congress and lost. (She was the first Indian-American to run for Congress back in 2010). Saujani’s lack of experience in coding didn’t stop her from launching what has become one of the most well-known coding camps in tech. Girls Who Code says it has helped train more than 670,000 young girls, women, and nonbinary individuals in STEM and, at one point, received support from high-profile names in the tech industry, including Jack Dorsey and Microsoft. (The organization still seems to be kicking, whereas other groups, like Girls in Tech and Women in Code, have faced the reverberating impacts of the anti-DEI sentiment sloshing through Silicon Valley.) Saujani chatted with Meghan about her early days of building the organization, while touching upon themes of motherhood and life after leaving Girls Who Code. Her interview illustrates the sacrifices many female founders make — and often conceal — while they focus on running a business. The conversation revealed Saujani’s drive as an entrepreneur to remain on the front lines pushing for change. “This conversation was such a full-circle moment for me,” Saujani told TechCrunch, adding that she first met Meghan when she expanded Girls Who Code to the UK in 2019. “Confessions of a Female Founder” promises to talk to important women and share lessons about building a business. The podcast, which launched last week, has had a successful beginning. It’s currently the No. 1-ranked business podcast on Apple, ahead of Scott Galloway’s “The Prof F Pod.” In a comment given to TechCrunch, Meghan said she hoped the conversation inspired others to “explore a different vertical of being an entrepreneur: social entrepreneurship.” “My conversations throughout ‘Confessions of a Female Founder’ have each been illuminating in their own way, and with Reshma, we chat about what it looks like for a woman to lead and succeed while also navigating motherhood with grit and grace,” she said. Saujani’s conversation is at its best when business nuggets are dropped. For instance, the pair discussed the adage that when you go to someone for money, you get advice, but if you go to someone for advice, you will probably get money. “You’re just going for advice, and then if it makes sense for them, they’ll offer up what they think you might need,” Meghan said. But there were intimate moments too; Saujani chatted about her struggles running the nonprofit while dealing with miscarriages and an auto-immune disorder. “I was performing in front of these children that I desperately wanted,” she said. “It was eating me up inside.” One of the main lessons in Saujani’s founder journey is, of course, taking leaps and not giving up. She took her chance in 2012 when she launched Girls Who Code after seeing that young women, especially women of color, were not entering STEM jobs. A child of Indian immigrants, she spoke about how she was bullied as a child and how that impacted her path in life. “I got beat up pretty bad,” she said, adding that she tried hard to assimilate into the white culture she grew up around. “But I also realized I am not white, and I’m never going to be, and I have a responsibility to actually teach people about difference [sic].” Betting on women another theme — and one worth reiterating. When Saujani launched her podcast, she thought it was important for young girls to have and understand the tools needed to solve the problems they will inevitably face. As the artificial intelligence revolution kicks off, betting on women has become more important than ever. Women make up just 22% of the global AI talent, with representation dropping as a role becomes more senior. AI is also threatening young women in unprecedented ways, most notably through the rise of shockingly accurate deepfake videos. (Girls Who Code says it has taught more than 8,000 students about AI). Saujani, now a mother, went on to launch Moms First, which advocates better working environments for moms. Meghan, she revealed, was an early supporter of the cause. The lesson there is a simple one. “I might die with women having less rights than they had when I was born,” she said, adding that she realized she, like other women, were probably put on earth to keep hope alive. “You lose, you lose, you lose, you lose, and then you win.”0 Comentários 0 Compartilhamentos 57 Visualizações

Watch this electric car demolish a 20-year-old F1 lap record and drive upside downWhat just happened? The McMurtry Speirling, an all-electric fan-assisted racecar, has added two more outrageous feats to its resume. Already known for obliterating the Goodwood Hillclimb record (bottom video), the Speirling just broke Top Gear's long-standing test track lap time - and became the first car to maintain sustained upside-down driving. The Speirling is a radically different approach to speed. Unlike most race cars that rely solely on power sent to the wheels, it devotes a chunk of its 1,000 horsepower to twin fans that suck air from beneath the chassis. The vacuum created dramatically increases downforce. The result is F1-level grip at any speed, not just high speed, giving it exceptional control when cornering, accelerating, or braking. The "fan car" idea isn't new. The Chaparral 2J and Brabham BT46B introduced the concept in the 1970s, but racing authorities quickly banned them for their an unfair advantage over racers using traditional aerodynamics. McMurtry's street-legal track weapon revives the idea with modern tech, generating twice its weight in downforce - 2,000kg on a 1,000kg car. That helped the Speirling demolish Top Gear's test track record with a lap time of 55.9 seconds. The previous best time, set by Renault's 2004 F1 car, was 59 seconds. Among street-legal cars, the Aston Martin Valkyrie was quickest at 1:08.3. Even Ford's outrageous electric Supervan 4.2, the fastest EV on the track until now, managed just 1:05.3. Electrek notes that McMurtry followed the lap record with another bold accomplishment: driving upside down, holding its inverted position for ten seconds while accelerating and braking a short distance at low speed. Hot Wheels once pulled off a loop-de-loop stunt with rally cars, but those relied on momentum rather than aerodynamic downforce. The Speirling maintained its inverted position using fan-driven suction, finally proving the long-standing theory that enough downforce can overcome gravity. Granted, the feat was more cautious than cinematic - it took place in a controlled setting, with safety in mind. Still, it's a world first that McMurtry called a "proof of concept." Speirling beating the Goodwood Hill Climb record in just 39.08 seconds. // Related Stories "With a longer inverted track or a suitable tunnel, we may be able to drive even further," McMurtry co-founder Thomas Yates noted. From record-breaking laps to gravity-defying stunts, the Speirling is no longer just a quirky science experiment. It's a real, working glimpse of what the future of racing - and extreme vehicle engineering - could look like.0 Comentários 0 Compartilhamentos 48 Visualizações

ARSTECHNICA.COMScientists made a stretchable lithium battery you can bend, cut, or stabBend it like a battery Scientists made a stretchable lithium battery you can bend, cut, or stab Its performance isn't great, but its endurance is similar to standard lithium-ion. Jacek Krywko – Apr 14, 2025 3:30 pm | 13 Story text Size Small Standard Large Width * Standard Wide Links Standard Orange * Subscribers only Learn more The Li-ion batteries that power everything from smartphones to electric cars are usually packed in rigid, sealed enclosures that prevent stresses from damaging their components and keep air from coming into contact with their flammable and toxic electrolytes. It’s hard to use batteries like this in soft robots or wearables, so a team of scientists at the University California, Berkeley built a flexible, non-toxic, jelly-like battery that could survive bending, twisting, and even cutting with a razor. While flexible batteries using hydrogel electrolytes have been achieved before, they came with significant drawbacks. “All such batteries could [only] operate [for] a short time, sometimes a few hours, sometimes a few days,” says Liwei Lin, a mechanical engineering professor at UC Berkeley and senior author of the study. The battery built by his team endured 500 complete charge cycles—about as many as the batteries in most smartphones are designed for. Power in water “Current-day batteries require a rigid package because the electrolyte they use is explosive, and one of the things we wanted to make was a battery that would be safe to operate without this rigid package,” Lin told Ars. Unfortunately, flexible packaging made of polymers or other stretchable materials can be easily penetrated by air or water, which will react with standard electrolytes, generating lots of heat, potentially resulting in fires and explosions. This is why, in 2017, scientists started to experiment with quasi-solid-state hydrogel electrolytes. These hydrogels were made of a polymer net that gave them their shape, crosslinkers like borax or hydrogen bonds that held this net together, a liquid phase made of water, and salt or other electrolyte additives providing ions that moved through the watery gel as the battery charged or discharged. But hydrogels like that had their own fair share of issues. The first was a fairly narrow electrochemical stability window—a safe zone of voltage the battery can be exposed to. “This really limits how much voltage your battery can output,” says Peisheng He, a researcher at UC Berkeley Sensor and Actuator Center and lead author of the study. “Nowadays, batteries usually operate at 3.3 volts, so their stability window must be higher than that, probably four volts, something like that.” Water, which was the basis of these hydrogel electrolytes, typically broke down into hydrogen and oxygen when exposed to around 1.2 volts. That problem was solved by using highly concentrated salt water loaded with highly fluorinated lithium salts, which made it less likely to break down. But this led the researchers straight into safety issues, as fluorinated lithium salts are highly toxic to humans. The challenge Lin, He, and their colleagues set for themselves was making a hydrogel battery with a wide electrochemical window—ideally above 3 volts—that would not cause severe chemical burns when damaged. Water-scarce hydrogels The chemistry of the battery they made started with a polymer that has both positive and negative charges (these are termed “zwitterionic”) as the structural net. Water molecules form hydrogen bonds with any charged parts, while lithium ions are attracted to its negatively charged parts. This way, the zwitterionic polymer could bind water tightly enough to prevent it from splitting at higher voltages while still releasing lithium ions when needed. The team then used acrylic acid as the gel’s crosslinker and an electrolyte with a fluorine-free lithium salt to provide lithium ions. Credit: He et al. The salt also played an additional role: It pulled water from the air. The usual way of getting the “hydro” part into a hydrogel is soaking the crosslinked, hydrophilic polymer in water; it will typically reach 80 percent water content. Lin, He, and their colleagues didn’t want their hydrogel to contain that much water because of the water-splitting issue. So they just left it to absorb water from ambient moisture. The result was a water-scarce hydrogel electrolyte that contained only 19 percent water and remained stable in a normal room humidity of 50 percent or so. Once the electrolyte was ready, the team added electrodes and built a fully functional battery powering a printed circuit with a few LED lights. The battery could work for over a month without sealed packaging and operate at over 3.1 volts without much water splitting—a voltage close to that used by commercial batteries. Despite this success, they started inflicting all sorts of punishment on it. Self-healing soft batteries The soft, jelly-like battery could power the LEDs when it was twisted 180 degrees, bent, punctured with a needle, and cut with a razor. It could even self-heal and get back to 90 percent of its original capacity after the team cut it in half, although this required putting it back together and warming it in an oven. Because the electrolyte reached its equilibrium state in ambient air, it didn’t degrade due to air exposure as other hydrogel electrolytes did and remained functional after 500 complete charge cycles. There were some drawbacks, though. A commercial battery designed for 500 cycles, in principle, should retain 80 percent of its capacity once those 500 cycles are done. Lin and He’s soft battery retained around 60 percent, which leaves lots of room for improvement. Another problem was the energy density. “When you compare this with state-of-the-art batteries we have today, we achieved roughly one-tenth of their capacity,” He says. “So, I think definitely we can try to optimize more towards energy density. Depending on the application, we may sacrifice some properties, like self-healing.” Lin, however, thinks that the relatively low energy density does not tell the full story. “Your smartwatch is powered by a battery, but a band for this watch today performs only the mechanical function,” Lin says. “If you can replace the band with our battery, you have more area, more volume to work with. Instead of needing a recharge once a day, it could perhaps work for, like, a week.” Science Advances, 2025.

WWW.BUSINESSINSIDER.COMA Chinese mercenary in Russia's invasion said he couldn't even go to the bathroom without an armed escortDuring a press conference on Monday, Zhang and Wang denied fighting against Ukraine voluntarily. GENYA SAVILOV/AFP via Getty Images 2025-04-15T08:32:52Z Save Saved Read in app This story is available exclusively to Business Insider subscribers. Become an Insider and start reading now. Have an account? Two Chinese prisoners of war spoke to the press on Monday, describing life under Russian forces. Both Chinese men said they were duped into becoming frontline soldiers for Russia. One of them said it was impossible to escape because he was constantly being watched. A Chinese man who said he was tricked into fighting for Russia's military told reporters on Monday that he was guarded so closely he couldn't go to the bathroom alone.Identified by Ukraine as 34-year-old Wang Guangjun, the man said at a Kyiv press conference that he had entered Russia believing he would be a rehabilitation therapist for Moscow's troops, only to discover he was being deployed on the front lines.Ukraine said on Wednesday that Wang and another Chinese man, 27-year-old Zhang Renbao, were captured in Donetsk. Business Insider could not independently verify statements from the prisoners of war.Both men said they were speaking to the press in hopes that China would notice their situation and negotiate for their release. They also denied fighting against Ukraine voluntarily.Wang described himself as being trapped after reporting for work in Moscow in early 2025, after which he was sent for a few days of training and later to Ukraine's front lines."Escape is impossible. Because from the moment you enter the training camp, if you go to the bathroom in the middle of the night, there will be a guard with a loaded gun following you," said Wang."And during training, your commander will keep a close eye on you. You have totally no opportunity to escape. Anyway, Russia is filled with military police, even if you try to run, there is nowhere to go," he added.Zhang — who said he was previously a rescue worker and firefighter in Shanghai — and Wang told Ukrainian and international reporters that they were promised monthly salaries of up to 280,000 rubles, or about $3,400.But they said they were often left in the dark and couldn't communicate well with their Russian-speaking officers. Wang added that he surrendered his mobile phone and was unsure if he was paid at all."I can very honestly tell everyone that I absolutely don't know the specifics," Wang said. "Because everything that involved us was kept secret."Russia's Defense Ministry did not respond to a request for comment sent outside regular business hours by BI.Wang and Zhang describe their capture Zhang is escorted by a Ukrainian armed guard at a press conference in Kyiv. GENYA SAVILOV/AFP via Getty Images Wang said he was deployed on April 1 in Donetsk with a unit that went by the "7th" — which could be a reference to Russia's 7th Motorized Rifle Brigade. The Chinese man said he could only communicate with his commanders via sounds and hand gestures.He told reporters that on April 4, he and several soldiers were sent to advance on the front lines in northern Donetsk. Wang said that as they neared their destination, a Russian soldier called his name and mimicked the sound of a gun firing, urging him to begin attacking."On the way there, we had gone through many Russian bunkers, so I thought we had arrived at our own friendly position. I thought he was joking," he said. "So I hid to one side."Wang then said that the "sky was filled with countless drones" that killed several of his comrades. The survivors soon surrendered to Ukrainian forces, he added.Meanwhile, Zhang said he arrived in Moscow as a tourist in December and, after seeking work there, was eventually shipped to Donetsk for a month.He said he and a small Russian squad were sent in late March to advance on foot at the front lines, then spent hours hiding and trying to survive repeated drone attacks."I just ran and ran and ran, until I eventually encountered Ukrainian soldiers," Zhang said.Ukraine says it has evidence that over 150 Chinese people are fighting for Russia, but added that there's no sign their presence is sanctioned by Beijing. On Friday, Reuters cited unnamed US officials saying that Washington believes most Chinese citizens fighting for Russia are mercenaries.China, meanwhile, said it has always told its citizens to stay away from the war."We call on the relevant party to be correct and sober about China's role and refrain from making irresponsible remarks," a spokesperson for Beijing's foreign ministry said on Thursday.
