The US observed Russian naval vessels preparing for a possible test of a new nuclear-powered torpedo in recent weeks, a senior US official with direct knowledge told CNN.
Among the vessels which took part in the preparations was the Belgorod, a cruise missile submarine modified for special operations that is able to launch unmanned underwater vehicles including the Poseidon torpedo.
In the last week, the vessels were observed leaving the testing area in the Arctic Sea and heading back to port without carrying out a test. The US believes the Russians may have encountered technical difficulties.
Vertical axis turbines missed their moment in the 1980s, but they are back, and they are getting bigger. That may come as a surprise. The technology was confined to niche applications and all but written off just a few years ago. Now they are poised for a new growth spurt in the rooftop field, and they are even heading out to sea.
The Long Road To Vertical Axis Wind Turbines
For those of you new to the topic, vertical axis wind turbines are engineered to make curved blades rotate around a central, upright pole. The US Department of Energy’s Sandia National Laboratory was experimenting with a scaled up design that resembled an egg beater back in the 1980s, as depicted in the photo at the top of this article.
Quantum mechanics, the theory which rules the microworld of atoms and particles, certainly has the X factor. Unlike many other areas of physics, it is bizarre and counter-intuitive, which makes it dazzling and intriguing. When the 2022 Nobel prize in physics was awarded to Alain Aspect, John Clauser and Anton Zeilinger for research shedding light on quantum mechanics, it sparked excitement and discussion.
But debates about quantum mechanics —be they on chat forums, in the media or in science fiction—can often get muddled thanks to a number of persistent myths and misconceptions. Here are four.
ISRIB, a tiny molecule identified by University of California, San Francisco (UCSF) researchers can repair the neural and cognitive effects of concussion in mice weeks after the damage, according to a new study.
ISRIB blocks the integrated stress response (ISR), a quality control process for protein production that, when activated chronically, can be harmful to cells.
The study, which was recently published in the Proceedings of the National Academy of Sciences, discovered that ISRIB reverses the effects of traumatic brain injury (TBI) on dendritic spines, an area of neurons vital to cognition. The drug-treated mice also showed sustained improvements in working memory.
A toddler is thriving after doctors in the U.S. and Canada used a novel technique to treat her before she was born for a rare genetic disease that caused the deaths of two of her sisters.
Ayla Bashir, a 16-month-old from Ottawa, Ontario, is the first child treated as a fetus for Pompe disease, an inherited and often fatal disorder in which the body fails to make some or all of a crucial protein.
Gene therapies can scale economically, but not just with practices adapted from traditional biologics. According to Avantor, gene therapies pose unique material, workflow, and partnering challenges.
Arthur C. Clarke, science fiction author and futurist, crossed paths with the scientists of the Bell System on numerous occasions. In 1945, he concurrently, but independently, conceived of the first concept for a communications satellite at the same time as Bell Labs scientist, John Robinson Pierce too, was a science fiction writer. To avoid any conflict with his day job at Bell Labs, Pierce published his stories under the pseudonym J.J. Coupling.
In the early 1960s, Clarke visited Pierce at Bell Labs. During his visit, Clarke saw and heard the voice synthesis experiments going on at the labs by John L. Kelly and Max Mathews, including Mathews’ computer vocal version of “Bicycle Built for Two”. Clarke later incorporated this singing computer into the climactic scene in the screenplay for the movie 2001: A Space Odyssey, where the computer HAL9000 sings the same song. According to Bob Lucky, another Bell Labs scientist, on the same visit, Clarke also saw an early Picturephone, and incorporated that into 2001 as well.
In 1976, AT&T and MIT held a conference on futurism and technology, attended by scientists, theorists, academics and futurists. This interview with Clarke during this conference is remarkably prescient—especially about the evolution of communications systems for the next 30+ years.
The interview was conducted for an episode of a Bell System newsmagazine, but this is the raw interview footage.
