Researchers design a pulsing nanomotor

Posted by in category: biotech/medical

An international team of scientists headed by the University of Bonn has developed a novel type of nanomotor. It is driven by a clever mechanism and can perform pulsing movements. The researchers are now planning to fit it with a coupling and install it as a drive in complex machines.

  • Researchers have developed a new type of nanomotor that performs pulsing movements similar to a hand grip trainer, but is a million times smaller.
  • The nanomotor uses RNA polymerases to move along a DNA strand, pulling its handles closer together in a cycle, mimicking the function of proteins in cells.

    Scientists propose ‘missing’ law for the evolution of everything in the universe

    The “law of increasing functional information” says that complex systems in nature evolve to become more complex.

    Ultra-bright light breakthrough could spark ‘technological and scientific revolution’

    Posted by in categories: innovation, particle physics

    A new method of producing an ultra-bright light which breaks traditional laws of particle physics could potentially spark a technological revolution.

    The ultra-bright light, a form of ‘coherent light’, is created by particles moving in synchrony rather than independently. This synchrony creates incredibly fast, intense pulses that operate on a scale of atto-seconds – or one thousandth of a millionth of a billionth of a second.

    While machines that can currently create ultra-bright light are miles long, scientists have now produced plans for a light source that can fit into a single room. The discovery could create a “mini-societal, technological and scientific revolution”, the researchers behind the development told BBC Science Focus.

    Accelerating the Future: World’s First Miniature Particle Accelerator Unveiled

    Posted by in categories: biotech/medical, nanotechnology

    Particle accelerators are crucial tools in a wide variety of areas in industry, research, and the medical sector. The space these machines require ranges from a few square meters to large research centers. Using lasers to accelerate electrons within a photonic nanostructure constitutes a microscopic alternative with the potential of generating significantly lower costs and making devices considerably less bulky.

    Until now, no substantial energy gains have been demonstrated. In other words, it has not been shown that electrons really have increased in speed significantly. A team of laser physicists at Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU) has now succeeded in demonstrating the first nanophotonic electron accelerator – at the same time as colleagues from Stanford University.

    Space Colonization

    While humans have long thought of gods living in the sky, the idea of space travel or humans living in space dates to at least 1,610 after the invention of the telescope when German astronomer Johannes Kepler wrote to Italian astronomer Galileo: “Let us create vessels and sails adjusted to the heavenly ether, and there will be plenty of people unafraid of the empty wastes. In the meantime, we shall prepare, for the brave sky-travellers, maps of the celestial bodies.” [1]

    In popular culture, space travel dates back to at least the mid-1600s when Cyrano de Bergerac first wrote of traveling to space in a rocket. Space fantasies flourished after Jules Verne’s “From Earth to the Moon” was published in 1,865, and again when RKO Pictures released a film adaptation, A Trip to the Moon, in 1902. Dreams of space settlement hit a zenith in the 1950s with Walt Disney productions such as “Man and the Moon,” and science fiction novels including Ray Bradbury’s The Martian Chronicles (1950).

    This startup wants to find out if humans can have babies in space

    Posted by in categories: biotech/medical, futurism

    Now Edelbroek is CEO of SpaceBorn United, a biotech startup seeking to pioneer the study of human reproduction away from Earth. Next year, he plans to send a mini lab on a rocket into low Earth orbit, where in vitro fertilization, or IVF, will take place. If it succeeds, Edelbroek hopes his work could pave the way for future space settlements.

    “Humanity needs a backup plan,” he says. “If you want to be a sustainable species, you want to be a multiplanetary species.”

    Beyond future space colonies, there is also a more pressing need to understand the effects of space on the human reproductive system. No one has ever become pregnant in space—yet. But with the rise of space tourism, it’s likely that it will eventually happen one day. Edelbroek thinks we should be prepared.

    China has a new plan for judging the safety of generative AI—and it’s packed with details

    Posted by in categories: government, law, robotics/AI, security

    A new proposal spells out the very specific ways companies should evaluate AI security and enforce censorship in AI models.

    Ever since the Chinese government passed a law on generative AI back in July, I’ve been wondering how exactly China’s censorship machine would adapt for the AI era.

    Last week we got some clarity about what all this may look like in practice.

    How Meta and AI companies recruited striking actors to train AI

    Posted by in category: robotics/AI

    Hollywood actors are on strike over concerns about the use of AI, but for as little as $300, Meta and a company called Realeyes hired them to make avatars appear more human.

    One evening in early September, T, a 28-year-old actor who asked to be identified by his first initial, took his seat in a rented Hollywood studio space in front of three cameras, a director, and a producer for a somewhat unusual gig.

    The two-hour shoot produced footage that was not meant to be viewed by the public—at least, not a human public.

    The Ray-Ban Meta smart glasses actually make the future look cool

    Posted by in categories: education, futurism

    While Meta hasn’t reinvented the category, it’s nailed the execution. But culturally, is the timing right for smart glasses?

    I’m a smart glasses skeptic. Not because the technology is impossible but because I’ve tested several pairs and even dove deep into the category for a two-part mini-documentary a while back. So when I say I was impressed by the $299 Ray-Ban Meta smart glasses, it’s not just that mine came with rose-colored lenses.

    To be clear, nothing about the Ray-Ban Meta smart glasses is revolutionary. The Google Glass Explorer Edition first introduced us to modern-day smart glasses in 2013. Several other companies, big and small, have since jumped on the bandwagon, including Snap, … More.
