Some deepfake videos present a convincing pulse Alamy Stock Photo Deepfake videos that feature digital manipulations of people’s facial expressions and voices can also depict realistic heartbeats, making them even harder to spot. “We now know that just because a person in a video has a measurable pulse, it doesn’t mean that we can assume…
All about AI Scientists are working on AI technology that has brain-inspired hardware, architecture or algorithms. Such neuromorphic AI could be nimbler, more efficient and more capable than traditional AI, freelance writer Kathryn Hulick reported in “Making AI think more like your brain.” Hulick reported that mainstream computers, which currently run most AI, separate memory…
CLIMATEWIRE | Time magazine selected Elon Musk as its “person of the year” in 2021 after the billionaire entrepreneur upended the car market, reinvigorated the space industry and funded a $100 million competition for climate technologies that would remove carbon dioxide from the air and sea. But Musk won’t attend Time’s event in New York…

The social media site Reddit is split into “subreddits” dedicated…
Athletic, crocodile-like reptiles with bladed teeth made their last stand in the Caribbean as recently as 4.5 million years ago. New fossils unearthed in the Dominican Republic suggest the reptile group went extinct millions of years later than previously thought, researchers report April 30 in Proceedings B of the Royal Society. The findings also help…

Climate change plays a role in disasters like Colorado’s Marshall fire, which destroyed 1000 homes in December 2021 Jim West/Alamy The Trump administration has dismissed all of the nearly 400 researchers working on the next US National Climate Assessment, a move likely to delay – if not prevent – the completion of this key report…
A new way of generating clean power could run your lights with rain. Hydropower typically relies on the movement of water to create electricity through mechanical energy, such as spinning turbines in a dam. But a new method, described April 16 in ACS Central Science, skips the mechanics and harnesses tiny bursts of energy sparked…
Trump Dismisses Scientists Writing Key Climate Report President Trump has dismissed hundreds of scientists working on the congressionally mandated National Climate Assessment, raising concerns about whether the void will be filled with pseudoscience By Scott Waldman & E&E News Firefighters watch as flames and smoke move through a valley in the Forest Ranch area of…
In the double-slit experiment, light waves interfere with each other – or do they? RUSSELL KIGHTLEY/SCIENCE PHOTO LIBRARY Light is both a wave and a particle – or so we have thought for about a hundred years. Since the advent of quantum physics, light has been understood to exhibit wave-particle duality. One part of this…
