Launching the drones from helicopters extends their reach and allows the aircraft to operate at further distances. US Marine Corps photo by Sgt. Symira Bostic US Marines tested deploying and controlling FPV drones from helicopters. They also passed control of a drone launched by ground forces to a helicopter miles away. These practices could deliver advantages in combat for Marines. US Marines have been trying out new roles for their H-1 helicopters, exploring whether they can serve as airborne launch and control platforms for first-person-view drones. The concepts combine crewed and uncrewed capabilities, using helicopters to extend the reach of small, low-cost drones, giving Marines another way to strike targets without pushing aircraft as deep into contested airspace. During a recent training exercise in California, Marines tested whether their helicopters could serve as "airborne motherships" for launching and FPV drones and aerial command centers for controlling them, the 3rd Marine Aircraft Wing said in a release. For the testing, Marines from Marine Light Attack Helicopter Squadron 169 and 3rd Light Armored Reconnaissance Battalion used two modern H-1 helicopters: the UH-1Y Venom utility helicopter, which entered service in 2008 as an upgrade to the UH-1N Twin Huey, and the AH-1Z Viper attack helicopter, which replaced the AH-1 SuperCobra. At the Twentynine Palms testing event, Marines successfully deployed an FPV drone from a moving helicopter. Marines also practiced handing off control to a distant helicopter with a line-of-sight connection. After Marine ground forces got their Neros Archer FPV drone flying, control of the uncrewed aircraft was passed to a specialized operator team inside a UH-1Y Venom helicopter miles away. That helicopter maintained the connection and flew the drone on to its target, functioning as a "flying command post" and "aerial control station." The 3rd Marine Aircraft Wing said that these approaches offer "commanders a scalable, cost-effective option to service a wide range of threats without risking the aircraft or expending expensive munitions on every target." The FPV drones were controlled by an operating team aboard another aircraft. US Marine Corps photo by Sgt. Symira Bostic The Neros Archer is the most popular first-person-view drone in the Marine Corps infantry. Necros has a $17 million contract with the Marines to build thousands of drones and has also produced systems for Ukraine. Like many FPV drones, the Archer can carry different payloads, and how far it can fly depends partly on how much weight it is carrying. The Marines used it for the test because it is already widely used and has performed well. Launching and controlling FPV drones from helicopters has the potential to reduce the risk to Marine aircrews, a UH-1Y crew chief said. "We are still providing our ground support, and close air support, but in a way that lets the drones close with and destroy the enemy, rather than putting our Marines in harm's way," said Sgt. Matthew Pocklington. More drones aboard the helicopters could allow onboard operators to potentially swarm the systems in coordinated attacks. Beyond the Marines' latest test, the US is more broadly focused on manned-unmanned teaming. The US Air Force and US Navy have several projects in the works that have advanced drones flying alongside crewed aircraft, either operating autonomously or taking direction from human pilots.

The author is so proud of all her children, but realizes she wasn't telling them. Courtesy of the author I often praised my children to others instead of to them directly. My upbringing made it hard for me to express encouragement openly. A painful conversation with my son changed how I parent adult kids. Several years ago, while driving behind a car with a "my-child-is-an-honor-student" bumper sticker, I said to my oldest son, sitting in the passenger seat, "I always wanted one of those." He, then a college student, replied, "Why? It doesn't mean anything." He was right. In the greater scheme of things, achieving honor roll in elementary or middle school is not a significant accomplishment. Nor is it a predictor of future success. Even so, I still wanted one! None of my five children was an academic superstar. They rarely achieved honor roll for more than one quarter of any school year, and none was named to the Dean's List in college. Nevertheless, I've always been exceedingly proud of each one. In fact, I'm constantly singing their praises to anyone who'll listen. The problem is, I rarely commend them directly. My parents did not praise me Maybe that's because my parents were not generous with praise. Their generation was not hardwired for affirmation, so I did not learn from experience how formative praise is. I was a well-behaved kid, a decent student, and a pretty compliant daughter. I didn't need positive reinforcement to motivate me, although it would have been nice to receive some occasionally. Growing up in the mid-20th century, the expectation for most girls like me was to earn an MRS, not an MBA. So, when in my senior year of high school, I was accepted into all five colleges I applied to, my parents were not over the moon with excitement. The day the fifth acceptance letter arrived from my first-choice school, I couldn't wait to share the news with my dad. I'd hoped he'd be as happy as I was. If he was, he didn't show it, and to this day, I still feel disappointed that he didn't give me a big hug and tell me he was proud. It shouldn't be so hard to say 'well done' I was effusive with praise when my kids were small. We celebrated each milestone from learning to use the toilet to tying their shoes to riding a bike. But as they've grown, I've been a much quieter cheerleader. The year my third son's Little League team won the championship I consoled him when he struck out but did not high-five him for hitting the line drive that clinched the series. When another son sang a solo during a school concert that was so beautiful it silenced the audience, I was too stunned to tell him he'd done an amazing job. Now that they're adults, each of my children is achieving great things. One's an artist in high demand. Another's a photographer whose work is published internationally. My youngest son, a UX designer, was recruited by a top tech company halfway through his junior year of college. My second son, who works in finance, created a unique investment vehicle that has launched his career into the stratosphere. Each of their successes is extraordinary, which is all the more reason I should tell them I'm proud. My kids want to know I'm proud of them Of course, I'm more than willing to tell friends, colleagues, and even mere acquaintances about all my kids accomplish. I post to Zoom chats and populate Slack channels with proud mama moments all the time. I share links to the Google alerts I've set up and forward their Reels from Instagram. I'm constantly sending photos in group chats, but I rarely send them texts to say how thrilled I am for them. I'm trying to figure out why I'm so reluctant. Maybe it's because I'm overwhelmed by their success. Where did the talent come from? Certainly not from me. Regardless, as their mother, I should congratulate them for all they're doing. I didn't realize just how important that is until my third son confronted me with an email I'd written years before about a photo essay he'd published. Instead of complimenting his work, I critiqued the composition. He was devastated by my comments. He'd worked hard on the project and had hoped I would recognize its value. Instead, I wrote about its flaws. When he read my words back to me, I was shocked. Not only did I not remember writing them, but I also had a hard time figuring out why I was so negative. I was ashamed I'd hurt him. At that moment, I realized no matter their age, my kids want my praise. Since then, I've been working really hard to tell each one just how proud of them I truly am. They're extraordinary people, and they should hear that often from their mother. Read the original article on Business Insider

Elon Musk's companies pay each other hundreds of millions of dollars a year, according to SpaceX's S-1. ODD ANDERSEN/AFP via Getty Images The newly public SpaceX S-1 reveals how closely Elon Musk's companies are connected. Last year, SpaceX was involved in more than $660 million worth of payments, goods, and services with the ventures. Here's a look at how SpaceX is intertwined with Tesla, The Boring Company, and more. Step right up to Elon Musk's financial merry-go-round. Tucked more than 200 pages into SpaceX's S-1 paperwork, which the company filed on Wednesday, is an outline of how interconnected Musk's various companies are, including through more than $660 million in payments, goods, and services involving SpaceX and his other ventures last year. Musk has his hands in many pots. In addition to being the CEO of aerospace company SpaceX, he's the CEO (and "Technoking") of electric carmaker Tesla, the founder of tunneling business The Boring Company, the cofounder of brain chip firm Neuralink, and was the CEO of xAI, until it merged with SpaceX in February. In various ways, the companies are all intermingled. SpaceX said in the filing that there may be "conflicts of interest," but ultimately, they benefit investors. It's not uncommon for companies with certain ties to do business with one another and to spell out these relationships in a prospectus filing when they plan to go public. The breakdown in SpaceX's S-1 is the first look we're getting at some of its connections, including SpaceX's deals with The Boring Company or its purchase of Tesla Cybertrucks. The biggest expenses between the companies fell under the banner of "commercial, licensing, and support." Last year, SpaceX paid Tesla $144 million under such agreements, a figure significantly higher than in years past. xAI, then a separate entity, spent more, paying Tesla $506 million last year. xAI, then a separate entity, spent more, paying Tesla $506 million last year, while also bringing in $2 millon in revenue from Tesla. The majority of SpaceX's cumulative $650 million in spending with Tesla was for Megapack products, Tesla's battery storage system. SpaceX also bought $131 million worth of Cybertrucks, which, at a starting retail price of $69,990 a pop, would be as many as 1,871 vehicles. Additionally, Tesla paid $4 million last year to advertise on X. Some expenses were driven by pure practicality: Tesla paid SpaceX $2 million to use its aircraft, X leased office space from The Boring Company for $1 million, and xAI rented space from the billionaire's umbrella company, Musk Industries LLC, for $2 million last year. SpaceX also spent $4 million on a security company owned by Musk for his personal security, as Tesla has done, per its filings. Other expenses were mind-scratchers. SpaceX paid The Boring Company $1 million in connection with the construction of tunnels in Bastrop, Texas. These could be the tunnels connecting his facilities reported by local outlets, or they could be related to the chip facility SpaceX is building there. Tesla and SpaceX's relationship is more than transactional Musk's companies plan to continue doing business together, particularly Tesla and SpaceX, which, the company said, have a "strong and constructive partnership." Tesla owns nearly 19 million shares of SpaceX stock. While that represents less than 1% of the company, at a target valuation of $1.5 trillion, those shares would be worth about $4.1 billion. SpaceX and Tesla also have major projects in the works. The pair is developing Macrohard, an agentic AI platform, and, along with Intel, has partnered on Terafab, a manufacturing initiative that creates chips for Tesla's robots and vehicles, as well as SpaceX's orbital compute infrastructure. The projects are set to be the beginning of a long relationship. "We plan to explore other areas of strategic collaboration with Tesla in the future," the document says.

Meta CEO Mark Zuckerberg sent an email to employees saying he didn't anticipate more companywide layoffs in 2026. Tom Williams/CQ-Roll Call, Inc via Getty Images Mark Zuckerberg's email struck an empathetic tone. He also said he didn't expect more companywide layoffs in 2026. Layoff anxiety can hurt worker productivity and morale, thereby carrying a real business cost. Workplace observers say his focus on stability suggests he recognizes the impact of prolonged uncertainty. Mark Zuckerberg is signaling that Meta employees can stop looking over their shoulders. After long emphasizing cost-cutting, management flattening, and "Year of Efficiency" rhetoric, the Meta chief struck an empathetic tone in his post-layoff email to employees on Wednesday — emphasizing stability, conceding communication failures, and promising to "do right by people along the way." In his internal email to staffers, he thanked the roughly 8,000 workers who were being let go and emphasized his desire to provide "as much stability as possible" to those who remained. It was a reminder that layoff anxiety carries a real business cost. To that point, Zuckerberg said that he doesn't expect further companywide layoffs in 2026. While that doesn't rule out smaller-scale cuts, the message followed weeks of grueling uncertainty for staffers waiting to learn whether they still had jobs. Zuckerberg's email — a shift away from the more hard-charging tone he adopted post-pandemic — suggested he recognizes that prolonged uncertainty can weigh on employees and, ultimately, the company itself, workplace observers told Business Insider. "You do need to try to create some psychological safety for people who are there, because layoffs are extremely distracting," said Amii Barnard-Bahn, a C-suite coach and consultant. 'We won't always get this balance right' Wednesday's cuts were the latest challenge for a workforce that has spent years navigating repeated rounds of layoffs, heightened performance scrutiny, and persistent questions about whether AI would take their jobs. It's a theme that has played out across tech, as companies increasingly tie cuts to AI and leaders warn about a white-collar bloodbath. In 2025, the CEO told staffers in an all-hands meeting to "buckle up" for an "intense" year ahead. Some of Meta's layoffs have come with an added sting: Last year, the company also said it was cutting some 4,000 workers who had failed to meet expectations. By the time the latest round arrived, the accumulation of uncertainty had drained some employees and left them wishing they were let go. Meta didn't respond to a request for comment from Business Insider. Were you impacted by Meta layoffs? We want to hear from you. Contact the reporters via email at tparadis@insider.com or aaltchek@insider.com, or secure-messaging platform Signal at tparadis.70. or aalt.19. Zuckerberg's Wednesday message hit on the toll that uncertainty around staffing levels can take: "We won't always get this balance right, but I care deeply about this so we'll keep adjusting and work hard to do right by people along the way," he wrote. It's not clear how effective Zuckerberg's softer tone might be, though he had little choice but to try to reassure those left standing, said Pav Stojkovic, an HR consultant and former chief people officer at several companies, including The Athletic. Zuckerberg's approach is a departure from one he'd used previously. In 2022, for example, Zuckerberg told Meta staff he was upping performance goals to get rid of employees who "shouldn't be here." By "turning up the heat a little bit," Zuckerberg said at the time that he hoped some workers would "decide that this place isn't for you, and that self-selection is OK with me." Last year, Meta directed managers to place a higher proportion of employees in its bottom review rankings. Zuckerberg has a long-standing history of ratcheting up the pressure at Meta, reinforcing a blunt, survival-of-the-fittest culture at the social media giant. The billionaire CEO is far from alone in embracing a sink-or-swim philosophy as AI reshapes the workplace. A focus on execution Zuckerberg's note comes at a transitional time for the industry. Excitement over the possibility of AI has mixed with fears over efficiency-driven job cuts and the encroachment of automation on workers' livelihoods. As Meta reshuffles roughly 7,000 employees to focus on new AI initiatives, Zuckerberg needs a workforce concentrated on execution amid the AI arms race. "Success isn't a given. AI is the most consequential technology of our lifetimes. The companies that lead the way will define the next generation," he wrote. Barnard-Bahn said it's likely that productivity at the company took a big hit in the last month, as workers worried about whether they or their colleagues would be cut or reorganized. By providing workers with a higher degree of job security for the next six-plus months, Zuckerberg might be offering employees something that Big Tech competitors have not. "Meta has the talent, the infrastructure, the apps and distribution, and the business model," Zuckerberg wrote. "We have a lot of work ahead, but what's on the other side is going to be extraordinary." Read the original article on Business Insider

Apple cofounder Steve Wozniak. Bloomberg/Bloomberg via Getty Images Steve Wozniak gave a commencement speech at Grand Valley State University earlier this month. He was cheered after telling students they had AI, or "actual intelligence." Students have booed some other execs who championed AI during their graduation speeches. Steve Wozniak did what other college graduation commencement speakers couldn't this year: earn applause when talking about AI. The Apple cofounder took the stage during Grand Valley State University's graduation ceremony earlier this month. During his speech, Wozniak offered reassurance to new graduates who are entering the workforce at the height of the AI revolution. "You have AI — actual intelligence," Wozniak said. The remark garnered laughs and applause from the audience. "It would take too long to go deeply into what I think about AI, but we've been trying to create a brain," Wozniak said. "Is there a way we can duplicate a routine a trillion times and have it work like a brain? AI is one of those attempts." While Wozniak delivered his speech without interruption, the same can't be said of some other AI-forward commencement speakers. In the weeks that followed, former Google CEO Eric Schmidt and real estate executive Gloria Caulfield were both booed for their comments about AI at two separate graduate ceremonies. AI is looming over new graduates as they enter the job market. The tech is changing the landscape, from the skills candidates need to how companies assess them. Its ability to automate many tasks has led some companies to conduct AI-related layoffs. During his commencement address, Wozniak reflected on working at Apple and offered students some advice as they begin their careers. "You should always try to think different," he said. "Don't follow the same steps as a million other people. Think, is there something I can do a little different?" Read the original article on Business Insider
