After raising almost $3 billion, Ginkgo Bioworks has built the world’s largest DNA factory in a bid to alter the code behind life and replace traditional manufacturing with biology.
The CEO of SES says consolidation of the satellite industry is more likely than ever to improve its overall return on investment.
MOUNTAIN VIEW, Calif. — The chief executive of satellite operator SES says consolidation of the satellite industry is more likely than ever to improve its overall return on investment, but that the structure of the industry might hinder such deals.
It’s not often that messing around in the lab has produced a fundamental breakthrough, à la Michael Faraday with his magnets and prisms. Even more uncommon is the discovery of the same thing by two research teams at the same time: Newton and Leibniz come to mind. But every so often, even the rarest of events does happen. The summer of 2021 has been a banner season for condensed-matter physics. Three separate teams of researchers have created a crystal made entirely of electrons — and one of them actually did it by accident.
The researchers were working with single-atom-thick semiconductors, cooled to ultra-low temperatures. One team, led by Hongkun Park along with Eugene Demler, both of Harvard, discovered that when very specific numbers of electrons were present in the layers of these slivers of semiconductor, the electrons stopped in their tracks and stood “mysteriously still.” Eventually colleagues recalled an old idea having to do with Wigner crystals, which were one of those things that exist on paper and in theory but had never been verified in life. Wigner had calculated that because of mutual electrostatic repulsion, electrons in a monolayer would assume a tri-grid pattern.
Please be sensitive to any artificial intelligence you encounter today. A UK appeals court just ruled that AI systems cannot submit or hold patents, as software is not human and therefore lacks human rights. Several courtrooms around the world have come to the same conclusion, despite the efforts of a very enthusiastic inventor.
Dr. Stephen Thaler has repeatedly filed patents on behalf of his AI, called DABUS. He claims that this AI should be credited for the inventions that it’s helped to produce. But patent offices disagree. After Dr. Thaler refused to resubmit his patents under a real name, the UK Intellectual Property Office pulled him from the registration process.
The key is an innovation that’s being called ‘light beads microscopy’. It improves on current two-photon microscopy, using lasers to trigger introduced fluorescence in living cells. As the cells are lit up, scientists can see how they’re moving and interacting.
With light beads microscopy, scientists can get the speed, scale, and resolution required to map a mouse brain in detail as its neural activity changes. The near-simultaneous tracking can last for as long as the light beads are able to stay illuminated.
CRISPR is the genius behind innovations that seemed impossible a decade ago. Could you grow tomatoes with the kick of hot sauce or ferment wine that doesn’t cause a hangover? That’s just two of the things scientists are looking into.
Welcome to AI book reviews, a series of posts that explore the latest literature on artificial intelligence.
Recent advances in deep learning have rekindled interest in the imminence of machines that can think and act like humans, or artificial general intelligence. By following the path of building bigger and better neural networks, the thinking goes, we will be able to get closer and closer to creating a digital version of the human brain.
