Tech Xplore / Video messaging effectiveness depends on quality of streaming experience, research shows
Low-resolution online videos are less likely to influence opinion and also more likely to dissuade viewers from engaging with future content, research by Oregon State University scientists shows. The study carries major implications ...
Tech Xplore / AI often escalates to nuclear action in war games
There are some things perhaps we might not want artificial intelligence to handle, at least for the time being. When leading chatbots were put through war-game simulations, they opted for nuclear signaling or escalation in ...
Tech Xplore / A 270-year-old physics trick could supercharge affordable battery technology
Roughly 270 years ago, Dr. Johann Gottlob Leidenfrost from Germany observed a peculiar behavior of water droplets on heated metal surfaces. In his manuscript, "A Tract About Some Qualities of Common Water," he described how ...
Tech Xplore / A clear view to better batteries: Engineers show moment lithium-ion batteries begin to fail
Lithium-ion batteries are ubiquitous in consumer electronics such as cellphones and in electric vehicles, but the surrounding temperature and speed of charging affect those batteries' performance, safety and lifespan. Fast ...
Tech Xplore / Improved EV battery gains will outmatch degradation from climate change, research shows
Climate change was poised to create an interesting catch-22 for electric vehicles. Electrifying transportation can go a long way to reducing carbon emissions that are driving up global temperatures. But warmer temperatures ...
Tech Xplore / A rewritable DNA hard drive may help solve the growing data storage crisis
Around the world, scientists are exploring an unexpected solution to the growing data crisis: storing digital information in synthetic DNA. The idea is simple but powerful—DNA is one of the most compact, durable information ...
Tech Xplore / Is this your AI? ZEN framework cracks AI black box
Artificial intelligence (AI) systems power everything from chatbots to security cameras, yet many of the most advanced models operate as "black boxes." Companies can use them, but outsiders can't see how they were built, ...
Tech Xplore / 'Milestone' findings on imaging methods call for a closer look at battery microscopy
Transmission electron microscopes (TEMs) allow researchers at the forefront of energy technology to study next-generation battery materials down to the atom. But new research has discovered that the very act of microscoping ...
Tech Xplore / Micro to mega engineering: Scaling up the 'world's smallest Nerf blaster'
BYU engineers had so much fun working with Mark Rober to create the "world's smallest Nerf blaster," they continued the work to see how big they could make it. The micro ant-blaster has become a mega launcher with the same ...
Tech Xplore / Extra 'set of eyes' for self-driving cars: Roadside radar sensors could reduce blind spots
Autonomous vehicles (AVs) are becoming increasingly common on roadways, but making them as safe as possible may entail going beyond the particular specs of the vehicles themselves to upgrading the roadway infrastructure. ...
Tech Xplore / Electron microscopy shows 'mouse bite' defects in semiconductors
Cornell researchers have used high-resolution 3D imaging to detect, for the first time, the atomic-scale defects in computer chips that can sabotage their performance. The imaging method, which was the result of a collaboration ...
Tech Xplore / Platforms for charging wireless cars now fit on a bench, no test track needed
Scientists from Tokyo Metropolitan University have devised a rotating tabletop device to study wireless charging in electric vehicles. Testing on real tracks takes up vast areas at significant cost. The team not only built ...
