WASHINGTON — The Department of Homeland Security (DHS) has published an updated space policy that emphasizes its roles in cybersecurity and resilience. The policy, less than three pages long, was signed by Secretary of Homeland Security Alejandro Mayorkas April 14. It was not published on the department’s website, though, for more than two months. “While

For the first time, physicists have witnessed something incredibly exciting: electrons forming whirlpools just like a fluid. This behavior is one that scientists have long predicted, but never observed before. And it could be the key to developing more efficient and faster next-generation electronics. “Electron vortices are expected in theory, but there’s been no direct

When disordered magnetic materials are cooled to just the right temperature, something interesting happens. The spins of their atoms ‘freeze’ and lock into place in a static pattern, exhibiting cooperative behavior not usually displayed. Now for the first time, physicists have seen the opposite. When fractionally heated, the naturally occurring magnetic element neodymium freezes, turning

WASHINGTON — Spacecraft controllers have restored communications with a lunar cubesat that went silent shortly after its deployment earlier this week. NASA and Advanced Space, the company operating the Cislunar Autonomous Positioning System Technology Operations and Navigation Experiment (CAPSTONE) cubesat, said the spacecraft started transmitting again early July 6. The spacecraft stopped communicating about 11

Physicists say they’ve found evidence in data from Europe’s Large Hadron Collider for three never-before-seen combinations of quarks, just as the world’s largest particle-smasher is beginning a new round of high-energy experiments. The three exotic types of particles – which include two four-quark combinations, known as tetraquarks, plus a five-quark unit called a pentaquark – are totally

Researchers have discovered never-before-seen types of crystal hidden in tiny grains of perfectly preserved meteorite dust. The dust was left behind by a massive space rock that exploded over Chelyabinsk, Russia, nine years ago. On 15 Feb 2013, an asteroid measuring 59 feet (18 meters) across and weighing 12,125 tons (11,000 metric tons) entered Earth‘s atmosphere at around

WASHINGTON — A NASA-funded lunar cubesat is on its way to the moon July 4 after a series of burns by a Rocket Lab transfer stage. Rocket Lab’s Lunar Photon stage released the Cislunar Autonomous Positioning System Technology Operations and Navigation Experiment (CAPSTONE) cubesat at 3:18 a.m. Eastern, shortly after the seventh and final burn

Holding a conversation with a five-year-old can be an adventure. One second you’re sharing opinions on favorite breakfast cereals, the next they’ve jumped ship to something vague about a cartoon octopus. What seems like a limited vocabulary or difficulty in keeping focused could actually be an inability to reconcile inferences with another person’s perspective. Researchers
