Unexpected hot spots in the cosmic microwave background (CMB) could have been produced by black holes evaporating before the Big Bang. So says a trio of scientists led by mathematical physicist Roger Penrose in a paper presenting new evidence that our universe is just one stage in a potentially infinite cycle of cosmic extinction and rebirth. Other […]Read more "New evidence for cyclic universe claimed by Roger Penrose and colleagues"
Despite how little we know about dark matter, we can tell when it’s there, from the way it impacts galaxies and causes strange movements that don’t fit the laws of gravity. Which means we can also tell when it’s not there. For the first time, astronomers using the Dragonfly Telephoto Array in New Mexico (and eventually the Hubble Space Telescope) discovered a distant galaxy […]Read more "A Transparent, Seemingly Impossible Galaxy Discovered"
Subvocalization signals are detected by electrodes and turned into words using AI If you’ve read any sort of science fiction, it’s likely you’ve heard about subvocalization, the practice of silently saying words in your head. It’s common when we read (though it does slow you down), but it’s only recently begun to be used as a way to […]Read more "MIT’s wearable device can ‘hear’ the words you say in your head"
Between the glowing blue and yellow swirls of distant galaxies, this tiny pinprick of light doesn’t look like much: a white smudge on the infinite black of the universe. But this tiny speck has enormous significance for astronomers. It’s the most distant star ever seen, affording astronomers a glimpse back in time. The star, MACS […]Read more "The Most Distant Star Scientists Have Ever Glimpsed"
While the possibility of an aircraft being struck by lightning is rare and does not present a threat to flight crews or pilots, aircraft manufacturers are looking to improve their current level of understanding of the interaction between aircraft and lightning. A new study published by several researchers from the Massachusetts Institute of Technology’s (MIT) Department of […]Read more "A New Method to Protect Aircraft From Lightning Strikes?"
From Edison to Elon, carbon fiber has been a source of inspiration and frustration. Carbon fiber is crucial to both the development of many current products, from golf clubs to jackets, and has the potential to be a crucial material in mankind’s quest to become interplanetary. With a history that starts with its use as […]Read more "The Past and Future of Carbon Fiber"
The team at the University of Wisconsin-Madison and Nanjing University have also simplified the manufacturing process for roll-to-roll production systems. The substrate is a transferable single crystalline Si nanomembrane (Si NM) 340nm thick on a single piece of bendable plastic substrate. The planar 1.5μm n-channel and p-channel MOSFETS and the NPN bipolar junction transistors […]Read more "Flexible BiCMOS substrate with simplified process for roll-to-roll production"
