Trump strikes “wild” deal making US firms pay 15% tax on China chip sales

fivenewscrypto    août 12, 2025   

Ahead of an August 12 deadline for a US-China trade deal, Donald Trump's tactics continue to confuse those trying to assess the country's national security priorities regarding its biggest geopolitical rival.

For months, Trump has kicked the can down the road regarding a TikTok ban, allowing the app to continue operating despite supposedly urgent national security concerns that China may be using the app to spy on Americans. And now, in the latest baffling move, a US official announced Monday that Trump got Nvidia and AMD to agree to "give the US government 15 percent of revenue from sales to China of advanced computer chips," Reuters reported. Those chips, about 20 policymakers and national security experts recently warned Trump, could be used to fuel China's frontier AI, which seemingly poses an even greater national security risk.

Trump’s “wild” deal with US chip firms

Reuters granted two officials anonymity to discuss Trump's deal with US chipmakers, because details have yet to be made public. Requiring US firms to pay for sales in China is an "unusual" move for a president, Reuters noted, and the Trump administration has yet to say what exactly it plans to do with the money.

Scientists hid secret codes in light to combat video fakes

Scientists hid secret codes in light to combat video fakes

fivenewscrypto    août 12, 2025   

It's easier than ever to manipulate video footage to deceive the viewer and increasingly difficult for fact checkers to detect such manipulations. Cornell University scientists developed a new weapon in this ongoing arms race: software that codes a "watermark" into light fluctuations, which in turn can reveal when the footage has been tampered with. The researchers presented the breakthrough over the weekend at SIGGRAPH 2025 in Vancouver, British Columbia, and published a scientific paper in June in the journal ACM Transactions on Graphics.

“Video used to be treated as a source of truth, but that’s no longer an assumption we can make,” said co-author Abe Davis, of Cornell University, who first conceived of the idea. “Now you can pretty much create video of whatever you want. That can be fun, but also problematic, because it’s only getting harder to tell what’s real.”

Per the authors, those seeking to deceive with video fakes have a fundamental advantage: equal access to authentic video footage, as well as the ready availability of advanced low-cost editing tools that can learn quickly from massive amounts of data, rendering the fakes nearly indistinguishable from authentic video. Thus far, progress on that front has outpaced the development of new forensic techniques designed to combat the problem. One key feature is information asymmetry: An effective forensic technique must have information not available to the fakers that cannot be learned from publicly available training data.

Experiment will attempt to counter climate change by altering ocean

Experiment will attempt to counter climate change by altering ocean

fivenewscrypto    août 12, 2025   

Later this summer, a fluorescent reddish-pink spiral will bloom across the Wilkinson Basin in the Gulf of Maine, about 40 miles northeast of Cape Cod. Scientists from the Woods Hole Oceanographic Institution will release the nontoxic water tracer dye behind their research vessel, where it will unfurl into a half-mile wide temporary plume, bright enough to catch the attention of passing boats and even satellites.

As it spreads, the researchers will track its movement to monitor a tightly controlled, federally approved experiment testing whether the ocean can be engineered to absorb more carbon, and in turn, help combat the climate crisis.

As the world struggles to stay below the 1.5° Celsius global warming threshold—a goal set out in the Paris Agreement to avoid the most severe impacts of climate change—experts agree that reducing greenhouse gas emissions won’t be enough to avoid overshooting this target. The latest Intergovernmental Panel on Climate Change report, published in 2023, emphasizes the urgent need to actively remove carbon from the atmosphere, too.

NASA plans to build a nuclear reactor on the Moon—a space lawyer explains why

NASA plans to build a nuclear reactor on the Moon—a space lawyer explains why

fivenewscrypto    août 12, 2025   

The first space race was about flags and footprints. Now, decades later, landing on the Moon is old news. The new race is to build there, and doing so hinges on power.

In April 2025, China reportedly unveiled plans to build a nuclear power plant on the Moon by 2035. This plant would support its planned international lunar research station. The United States countered in August, when acting NASA Administrator Sean Duffy reportedly suggested a US reactor would be operational on the Moon by 2030.

While it might feel like a sudden sprint, this isn’t exactly breaking news. NASA and the Department of Energy have spent years quietly developing small nuclear power systems to power lunar bases, mining operations, and long-term habitats.

Encryption made for police and military radios may be easily cracked

Encryption made for police and military radios may be easily cracked

fivenewscrypto    août 12, 2025   

Two years ago, researchers in the Netherlands discovered an intentional backdoor in an encryption algorithm baked into radios used by critical infrastructure–as well as police, intelligence agencies, and military forces around the world–that made any communication secured with the algorithm vulnerable to eavesdropping.

When the researchers publicly disclosed the issue in 2023, the European Telecommunications Standards Institute (ETSI), which developed the algorithm, advised anyone using it for sensitive communication to deploy an end-to-end encryption solution on top of the flawed algorithm to bolster the security of their communications.

But now the same researchers have found that at least one implementation of the end-to-end encryption solution endorsed by ETSI has a similar issue that makes it equally vulnerable to eavesdropping. The encryption algorithm used for the device they examined starts with a 128-bit key, but this gets compressed to 56 bits before it encrypts traffic, making it easier to crack. It’s not clear who is using this implementation of the end-to-end encryption algorithm, nor if anyone using devices with the end-to-end encryption is aware of the security vulnerability in them.

New adhesive surface modeled on a remora works underwater

New adhesive surface modeled on a remora works underwater

fivenewscrypto    août 11, 2025   

Most adhesives can’t stick to wet surfaces because water and other fluids disrupt the adhesive’s bonding mechanisms. This problem, though, has been beautifully solved by evolution in remora suckerfish, which use an adhesive disk on top of their heads to attach to animals like dolphins, sharks, and even manta rays.

A team of MIT scientists has now taken a close look at these remora disks and reverse-engineered them. “Basically, we looked at nature for inspiration,” says Giovanni Traverso, a professor at MIT Department of Mechanical Engineering and senior author of the study.

Sticking Variety

Remora adhesive disks are an evolutionary adaptation of the fish’s first dorsal fin, the one that in other species sits on top of the body, just behind the head and gill covers. The disk rests on an intercalary backbone—a bone structure that most likely evolved from parts of the spine. This bony structure supports lamellae, specialized bony plates with tiny backward-facing spikes called spinules. The entire disk is covered with soft tissue compartments that are open at the top. “This makes the remora fish adhere very securely to soft-bodied, fast-moving marine hosts,” Traverso says.

fivenewscrypto    août 11, 2025   

James Lovell, a member of humanity's first trip to the moon and commander of NASA's ill-fated Apollo 13 mission, has died at the age of 97.

Lovell's death on Thursday was announced by the space agency.

"NASA sends its condolences to the family of Capt. Jim Lovell, whose life and work inspired millions of people across the decades," said acting NASA Administrator Sean Duffy in a statement on Friday. "Jim's character and steadfast courage helped our nation reach the moon and turned a potential tragedy into a success from which we learned an enormous amount. We mourn his passing even as we celebrate his achievements."
