Why we need to ditch dark matter for a new theory of gravity

We can model the motions of planets in the Solar System quite accurately using Newton’s laws of physics. But in the early 1970s, scientists noticed that this didn’t work for disc galaxies – stars at their outer edges, far from the gravitational force of all the matter at their center – were moving much faster than Newton’s theory predicted. This made physicists propose that an invisible substance called “dark matter” was providing extra gravitational pull, causing the stars to speed up – a theory that’s become hugely popular. However, in a recent review, my colleagues and I suggest that observations…

Swiss startup believes this forgotten element is the key to safe nuclear energy

Nuclear energy is undergoing a renaissance. Across Europe, governments are pouring huge amounts of money into new power plants while startups are busily working on smaller, modular alternatives. Most of these plants rely on uranium, the radioactive metal that fuelled the atomic age (and contributed to a couple of catastrophic meltdowns). However, Swiss startup Transmutex wants to reinvent nuclear energy using a lesser-known element called thorium. Uranium’s forgotten cousin Thorium is a lead-like metal that is mildly reactive, but four times more abundant than uranium and a lot safer to handle. However, thorium is a fissionable material but not a… This story continues at The Next Web from The Next Web https://ift.tt/ideQqVM

Insta mules and crypto mixers: How tech is transforming money laundering

On the shallow surface of Instagram, Ramon “Hushpuppi” Abbas was a quintessential influencer. The flamboyant Nigerian portrayed a lavish lifestyle of private jets, luxury cars, and designer clothes. His glamorous adventures had earned him over 2 million followers and millions of dollars. But his posts concealed a darker reality. The 41-year-old was “one of the most prolific money launderers in the world,” according to the FBI. By his own admission, Hushpuppi conspired to launder over $300mn in just 18 months. One of his alleged clients was a certain Kim Jong Un — the supreme leader of North Korea. With his… This story continues at The Next Web from The Next Web https://ift.tt/rd549ui
