What if stopping life-threatening bleeding could be as simple as injecting a gel? That’s the promise of TRAUMAGEL, a groundbreaking, plant-based bleeding control gel now being used by first responders across the country, including a metro Atlanta fire department that recently used it to save one of their own. Developed by Cresilon CEO and co-founder Joe Landolina, TRAUMAGEL works in seconds to control bleeding from gunshot wounds and other traumatic injuries. It’s supplied in a compact 30-ml syringe and can be quickly applied in the field before a patient bleeds out, a risk responsible for more than 35% of all prehospital deaths.STANFORD RESEARCHERS DEVELOP ‘GAME-CHANGING’ STROKE TREATMENT THAT DOUBLES EFFECTIVENESSSign up for my FREE CyberGuy ReportGet my best tech tips, urgent security alerts, and exclusive deals delivered straight to your inbox.

(Cresilon)A medical breakthrough born in a winery labThe story behind TRAUMAGEL starts with a teenager in a winery lab. Joe Landolina, now CEO of Cresilon, developed the technology when he was just 17.”My grandfather was a retired chemist who owned a vineyard in upstate New York,” Landolina explains. “I would work alongside him in his winery laboratory every single day after school from a very young age. During that time, I developed a strong love for chemistry, especially plant-based chemistries from ingredients found in nature around me.”That love turned into research. “At the age of 17, I was experimenting with polymers extracted from the cell walls of algae and discovered a matrix that would instantly bond to living tissue,” he said.He took the idea to New York University’s business plan competition, and Cresilon was born. The company now operates out of a 55,000-square-foot biomanufacturing facility in Brooklyn with nearly 100 employees. TRAUMAGEL works in seconds to control bleeding from severe injuries. (Cresilon)Real-world impact: Faster bleeding control in the fieldTRAUMAGEL is already changing how medics respond in high-pressure trauma situations.”TRAUMAGEL has impacted how we respond to traumatic injuries in any situation,” says Lt. David Kleiman of Cobb County Fire & Emergency Services. “In the past, with junctional injuries, like the neck, armpit, or groin, we were using traditional methods like digital pressure or wound packing. That required multiple crews and took time.”With TRAUMAGEL, we can administer a hemostatic agent that controls bleeding in seconds,” he continues. “Crews can move on to quicker assessments and treatments and get the patient to definitive care faster.”MAN’S DEADLY BRAIN CANCER TUMOR DISAPPEARS AFTER EXPERIMENTAL DRUG TRIALHow it saved a firefighter’s lifeIn one recent case, a Cobb County firefighter was injured during a response at an abandoned house. He tripped on a hill, cut his hand on broken glass, and attempted to stop the bleeding himself. But it didn’t work.”He eventually realized he couldn’t control the bleeding and made his way back to the engine,” Kleiman recalls. “The crew noted that he was pale and sweaty and that his turnout gear was saturated in blood. Traditional methods failed, so they administered TRAUMAGEL. It instantly stopped the bleeding.”The firefighter was then treated for blood loss and fully recovered after surgery.  Cresilon CEO and co-founder Joe Landolina (center) and his team stand with Cobb County Fire & Emergency Services. (Cresilon)From fire departments to the Department of DefenseCresilon’s bleeding control gel is being tested in even more demanding environments.”In addition to getting TRAUMAGEL into the hands of all first responders across the country,” Landolina says, “our proprietary technology is being studied for broader applications by the U.S. Defense Department’s Walter Reed Army Institute of Research.”That study is focused on penetrating traumatic brain injuries (TBI). “Preliminary findings demonstrated promising results in the ability of our technology to control bleeding and provide neuroprotection following a TBI,” he says. The team plans to pursue further research based on those results. What this means for youSevere bleeding is the number one cause of preventable death from trauma. With TRAUMAGEL, emergency teams can control that bleeding quickly, even before a patient reaches the hospital. This tool isn’t just for battlefield medicine or professional EMS. In the future, you could see it in hospitals, dental offices, and even home first-aid kits. TRAUMAGEL may become a new standard in emergency bleeding control, and that means faster care, better outcomes, and more lives saved.Take my quiz: How safe is your online security?Think your devices and data are truly protected?

Estonia marked its 10th anniversary in the European Space Agency alongside the plenary session of the European Interparliamentary Space Conference on 4 September.  

The conference is presided over by a different country each year and serves as a permanent forum for interparliamentary discussions among national parliaments interested in space policy.  ESA Director General Josef Aschbacher was joined by Director of Connectivity and Secure Communications Laurent Jaffart for the conference and anniversary celebrations. The ESA Director General spoke about expectations for space in the next decade, alongside Estonian member of parliament Mario Kadastik, and moderator Hermann Ludwig Moeller, the Director of the European Space Policy Institute. They reflected on the need for increased work on security and resilience – in line with the topic of the conference ‘Security in Space: Europe’s challenges and opportunities’, but also on the opportunities space can bring to academia and industry.

Estonia also hosted an information day looking ahead to ESA’s Ministerial Council in November, highlighting the opportunities for Estonian companies to engage with new missions and programmes.  The ESA delegation had the opportunity to meet government ministers before visiting the TalTech School of Business and Governance to engage with members of the public in Tallinn.  At an evening reception, the Director General thanked Estonia for the skills and enthusiasm the country brings to ESA, and in looking back on 10 successful years, also looked ahead to a bright future.

NASA and Northrop Grumman are preparing to send the company’s next cargo mission to the International Space Station, flying research to support Artemis missions to the Moon and human exploration of Mars and beyond, while improving life on Earth. SpaceX’s Falcon 9 rocket will launch Northrop Grumman’s 23rd commercial resupply services mission to the orbiting laboratory.The investigations aboard the Cygnus spacecraft aim to refine semiconductor crystals for next-generation technologies, reduce harmful microbes, improve medication production, and manage fuel pressure.
NASA, Northrop Grumman, and SpaceX are targeting launch in mid-September from Space Launch Complex 40 at Cape Canaveral Space Force Station in Florida.
Read about some of the investigations traveling to the space station:

Researchers are continuing to fine-tune in-space production of semiconductor crystals, which are critical for modern devices like cellphones and computers.
The space station’s microgravity environment could enable large-scale manufacturing of complex materials, and leveraging the orbiting platform for crystal production is expected to lead to next-generation semiconductor technologies with higher performance, chip yield, and reliability.
“Semiconductor devices fabricated using crystals from a previous mission demonstrated performance gain by a factor of two and device yield enhanced by a factor of 10 compared to Earth-based counterparts,” said Partha S. Dutta, principal investigator, United Semiconductors LLC in Los Alamitos, California.
Dutta highlighted that three independent parties validated microgravity’s benefits for growing semiconductor crystals and that the commercial value of microgravity-enhanced crystals could be worth more than $1 million per kilogram (2.2 pounds).
Space-manufactured crystals could help meet the need for radiation-hardened, low-power, high-speed electronics and sensors for space systems. They also could provide reduced power use, increased speed, and improved safety. The technology also has ground applications, including electric vehicles, waste heat recovery, and medical tools.

Researchers are examining how microgravity affects ultraviolet (UV) light’s ability to prevent the formation of biofilms — communities of microbes that form in water systems. Investigators developed special optical fibers to deliver the UV light, which could provide targeted, long-lasting, and chemical-free disinfection in space and on Earth.
“In any water-based system, bacterial biofilms can form on surfaces like pipes, valves, and sensors,” said co-investigator Paul Westerhoff, a professor at Arizona State University in Tempe. “This can cause serious problems like corrosion and equipment failure, and affect human health.”
The UV light breaks up DNA in microorganisms, preventing them from reproducing and forming biofilms. Preliminary evidence suggests biofilms behave differently in microgravity, which may affect how the UV light reaches and damages bacterial DNA.
“What we’ll learn about biofilms and UV light in microgravity could help us design safer water and air systems not just for space exploration, but for hospitals, homes, and industries back on Earth,” Westerhoff said.
Learn more about the GULBI experiment.

An investigation using a specialized pharmaceutical laboratory aboard the space station examines how microgravity may alter and enhance crystal structures of drug molecules. Crystal structure can affect the production, storage, effectiveness, and administration of medications.
“We are exploring drugs with applications in cardiovascular, immunologic, and neurodegenerative disease as well as cancer,” said principal investigator Ken Savin of Redwire Space Technologies in Greenville, Indiana. “We expect microgravity to yield larger, more uniform crystals.”
Once the samples return to Earth, researchers at Purdue University in West Lafayette, Indiana, will examine the crystal structures.
The investigators hope to use the space-made crystals as seeds to produce significant numbers of crystals on Earth.
“We have demonstrated this technique with a few examples, but need to see if it works in many examples,” Savin said. “It’s like being on a treasure hunt with every experiment.”
This research also helps enhance and expand commercial use of the space station for next-generation biotechnology research and in-space production of medications.
Learn more about the ADSEP PIL-11 experiment.

Many spacecraft use cryogenic or extremely cold fluids as fuel for propulsion systems. These fluids are kept at hundreds of degrees below zero to remain in a liquid state, making them difficult to use in space where ambient temperatures can vary significantly. If these fluids get too warm, they turn into gas and boiloff, or slowly evaporate and escape the tank, affecting fuel efficiency and mission planning.
A current practice to prevent this uses  onboard fuel to cool systems before transferring fuel, but this practice is wasteful and not feasible for Artemis missions to the Moon and future exploration of Mars and beyond. A potential alternative is using special gases that do not turn into liquids at cold temperatures to act as a barrier in the tank and control the movement of the fuel.
Researchers are testing this method to control fuel tank pressure in microgravity. It could save an estimated 42% of propellant mass per year, according to Mohammad Kassemi, a researcher at NASA’s National Center for Space Exploration Research and Case Western Reserve University in Cleveland.
The test could provide insights that help improve the design of lightweight, efficient, long-term in-space cryogenic storage systems for future deep space exploration missions.

The Navy, working with Skydweller Aero, just reached a major milestone in clean-energy aviation. Its solar-powered drone, known as Skydweller, flew for 73 hours straight without needing fuel. The test happened at Stennis, Mississippi, under the leadership of the Naval Air Warfare Center Aircraft Division (NAWCAD).This breakthrough shows how renewable energy can power long-endurance missions while cutting costs and reducing reliance on fuel.AMERICA’S SKIES ARE WIDE OPEN TO NATIONAL SECURITY THREATS, DRONE EXPERT WARNS: ‘WE HAVE NO AWARENESS’Sign up for my FREE CyberGuy ReportGet my best tech tips, urgent security alerts and exclusive deals delivered straight to your inbox. Plus, you’ll get instant access to my Ultimate Scam Survival Guide — free when you join my CYBERGUY.COM newsletter. The Navy flew a drone nonstop for over three days to test new long-endurance solar-powered autonomous aircraft technology. (Naval Air Warfare Center Aircraft Division)Navy solar drone proves nonstop enduranceThe three-day nonstop flight proved that solar-powered drones can store enough energy during daylight to keep flying through the night. Engineers confirmed that Skydweller not only stayed airborne but also handled real-time autonomous decisions, adapted to turbulent weather and maintained secure communications.AI DRONE FINDS MISSING HIKER’S REMAINS IN MOUNTAINS AFTER 10 MONTHSOfficials say the drone’s wingspan matches that of a Boeing 747, yet it weighs about as much as a Ford F-150. With solar panels covering its massive wings, Skydweller powers four electric propeller engines during the day while storing extra energy in batteries for night flights. The Navy, in partnership with Skydweller Aero, recently achieved continuous solar-powered unmanned flight during a nonstop three-day test. (Naval Air Warfare Center Aircraft Division)Navy expands solar-powered surveillanceNAWCAD leaders say Skydweller will fit into the Navy’s intelligence, surveillance and reconnaissance (ISR) network. Unlike expensive satellites or large drones such as the Global Hawk, Skydweller offers commanders a cheaper option for persistent monitoring. It can hover over an area in what experts call a “pseudo-satellite role,” freeing up more advanced systems for priority missions.For U.S. Southern Command, Skydweller could help track drug trafficking, border security threats and other maritime challenges. Longer tests are already planned for this summer in the SOUTHCOM region, which covers Latin America and the Caribbean and oversees U.S. military operations in that area. A solar-powered aircraft sits at Skydweller’s facility at Albacete airport on April 3, 2023, in Albacete, Castilla-La Mancha, Spain. (Rey Sotolongo/Europa Press via Getty Images)Future of solar-powered flight for Navy missionsWhile Skydweller has already logged nearly 220 flight hours, engineers believe it could stay airborne far longer. Weather and range limits kept this recent test at 73 hours, but in theory, the aircraft could remain aloft for weeks.The Department of Defense sees platforms like Skydweller as vital for future conflicts where fuel resupply may not be possible. Renewable-powered drones could solve logistics headaches, especially in contested environments, which essentially means operating in places where enemies can block supply lines and make traditional refueling too risky.What this means for youThe Navy’s solar drone test is proof that renewable energy can support technologies once thought impossible. If solar power can keep an aircraft in the air for days, similar advances may eventually reach consumer tech, disaster relief and even commercial aviation.

Downsizing should feel like a fresh start. A smaller home, less upkeep, maybe even a retirement community with new friends. In fact, more than 3 million elderly Americans move every year. Are you considering downsizing as well?One woman told the internet about moving her mother into an assisted living home. Before the boxes were even packed, her mother fell for two back-to-back scams. It wasn’t bad luck; scammers had picked up on her address and pounced.This isn’t rare. Researchers have found that over 70 percent cybercrimes trace back to exposed personal data. And moving creates one of the biggest exposures of all. Real estate listings, moving companies and address changes get scooped up by data brokers and published online, the perfect setup for criminals to strike.Sign up for my FREE CyberGuy ReportGet my best tech tips, urgent security alerts and exclusive deals delivered straight to your inbox.

(Kurt “CyberGuy” Knutsson)How to protect your personal data when you moveWhile moving creates new opportunities, it also creates new risks. These simple steps will help you lock down your personal data before scammers can exploit it.1) Remove your info from data broker sitesData brokers automatically update your file when you move. That means your new address, phone number and even property transaction details can end up on people-search websites almost overnight. Once your profile is out there, scammers can buy or scrape it with ease.The good news: you don’t have to chase down every broker yourself. A personal data removal service does the legwork for you, contacting data brokers, demanding removal and following up to make sure your new details don’t creep back in. Think of it as hiring a moving company for your personal data.While no service can guarantee the complete removal of your data from the internet, a data removal service is really a smart choice.  They aren’t cheap, and neither is your privacy.  These services do all the work for you by actively monitoring and systematically erasing your personal information from hundreds of websites.  It’s what gives me peace of mind and has proven to be the most effective way to erase your personal data from the internet.  By limiting the information available, you reduce the risk of scammers cross-referencing data from breaches with information they might find on the dark web, making it harder for them to target you.Check out my top picks for data removal services and get a free scan to find out if your personal information is already out on the web by visiting Cyberguy.com.Get a free scan to find out if your personal information is already out on the web: Cyberguy.com.2) Use the official USPS form onlyWhen you change your address, always use the official USPS website or your local post office. Some third-party sites look like they’re offering a convenient service, but they often collect extra data about you and sometimes even resell it. Going straight to the source means your sensitive details don’t take unnecessary detours.3) Watch real estate disclosuresWhen you sell your home, more than just the price gets published. Your name, past addresses and even photos of your home can become part of the public record. Ask your realtor what’s automatically disclosed and whether anything can be limited or redacted. It’s worth being picky here: the less of your personal footprint that’s tied to your property, the better.4) Shred old paperworkMoving is the perfect excuse to purge. But don’t just throw out old bills, medical statements, or financial records; shred them. Dumpster-diving for personal data may sound outdated, but it’s still a method scammers use. A good shredder ensures your sensitive history doesn’t end up in the wrong hands.5) Share moving news privatelyIt’s tempting to post a “Goodbye, old house!” photo online, but resist the urge. Publicly announcing a move tells scammers exactly when your home is empty and what your new address might be. Instead, share the news directly with family and close friends. A little less buzz online means a lot more safety offline.6) Freeze your credit before and after movingOne powerful way to stay ahead of scammers is to freeze your credit. A freeze blocks new credit accounts from being opened in your name, even if criminals have your address or other details. The good news is that you can do this for free with all three major credit bureaus: Equifax, Experian and TransUnion.It only takes a few minutes online or by phone, and you can lift the freeze anytime if you need to apply for a loan or credit card. By freezing your credit before and after your move, you create a strong barrier that keeps thieves from turning stolen data into financial damage.CLICK HERE TO GET THE FOX NEWS APPKurt’s key takeawaysMoving should feel like a new beginning, not an invitation for scammers to strike. With a few smart steps, you can stay ahead of data brokers and fraudsters. From shredding documents to freezing your credit, every action adds a layer of protection.

Self-driving trucks are moving closer to reality. PlusAI released its first half 2025 performance results, showing how far the company has come toward its goal of launching factory-built autonomous trucks in 2027.The numbers are clear. Safety case readiness reached 86 percent, with a goal of 100 percent by launch. Autonomous miles percentage climbed to 98 percent. Remote assistance free trips rose to 76 percent, with a target of more than 90 percent.These metrics may sound technical, but they show that PlusAI is moving steadily toward putting driverless freight trucks on the road within two years.Sign up for my FREE CyberGuy ReportGet my best tech tips, urgent security alerts, and exclusive deals delivered straight to your inbox. Plus, you’ll get instant access to my Ultimate Scam Survival Guide – free when you join my CYBERGUY.COM newsletter.159-YEAR-OLD COMPANY EMBRACES DRIVERLESS TRUCKS PlusAI reports that its driverless trucks could be ready to hit the road within the next two years. (PlusAI)Why PlusAI’s 2025 results matter for autonomous trucksEven if you never step into a truck, these results affect your daily life. Every product you buy travels by truck at some point, whether it’s groceries, clothing or furniture. The way those trucks operate influences cost, availability and safety on the road.The trucking industry faces three major challenges. There are not enough long-haul drivers to meet demand. Costs continue to rise due to labor shortages, tariffs and fuel prices. And safety is a concern because human drivers can get tired or distracted.Autonomous trucks could help address each of these issues. PlusAI’s vehicles are already hauling freight on Texas highways today, and they are also undergoing road testing in Sweden. The company has already logged more than five million autonomous miles across the United States, Europe and Asia. That real-world experience fuels the AI system with the data it needs to improve.LUCID JOINS TESLA AND GM WITH HANDS-FREE HIGHWAY DRIVING The PlusAI Safety Case Framework. Data shows that self-driving trucks will roll out by 2027. (PlusAI)How PlusAI plans to launch autonomous trucks by 2027PlusAI has created a roadmap that sets it apart. Instead of retrofitting trucks with autonomous systems, it is working with major manufacturers like TRATON GROUP, Hyundai and IVECO to integrate the technology at the factory. This approach makes scaling production faster and ensures consistency.The initial launch is planned for the Texas Triangle, a major freight corridor connecting Dallas, Houston, San Antonio and Austin. From there, PlusAI plans to expand into other U.S. routes and eventually Europe.The company has also committed to publishing regular performance updates as it transitions to a public company. By sharing measurable results, PlusAI builds trust with regulators, the public, and businesses that may one day rely on its trucks to move goods.”We have a clear roadmap to the commercial launch of SuperDrive,” said David Liu, CEO and co-founder of PlusAI. “By publicly sharing these performance metrics, we are showing our commitment to safety and scalability while bringing partners, customers, and regulators along on this journey.”What’s next for PlusAI and driverless freight trucks?PlusAI still has milestones to meet.

On July 26, 2025, NASA astronaut Nichole Ayers took this long-exposure photograph – taken over 31 minutes from a window inside the International Space Station’s Kibo laboratory module – capturing the circular arcs of star trails.
