Phys.org / Aliens might exist, but there are three reasons why they're not visiting us
The United States government's recent release of hundreds of previously classified unidentified anomalous phenomena (UAPs) cases spanning the 1940s to the present, along with the new Steven Spielberg movie, "Disclosure Day," ...
Medical Xpress / Legalizing cannabis increases use and addiction, unless it is tightly controlled, says research
Removing criminal penalties for possessing cannabis for personal use, or introducing tightly controlled legalization of cannabis, does not appear to increase levels of cannabis use. However, the commercial sale of cannabis ...
Phys.org / The hidden physics complicating interstellar lightsails
If we're to reach another star, chemical propulsion will not get us there in any reasonable time frame. We're going to need a different propulsion technology, and one of the most promising seems to be a solar sail. These ...
Phys.org / Why birds ignore Newton: New theory could sharpen models of flocks, crowds and cells
Birds in flocks, bacteria and cells: In many collective systems, individual elements respond to only part of their surroundings, seemingly defying Newton's third law of motion—action equals reaction. These exceptions are ...
Phys.org / Cockroach genomes are packed with DNA transferred by their endosymbiont bacterial partners
Genes aren't just transferred from parents to their offspring. Nature has found other ways to pass on genetic information, even between different species. And a new study, published in the journal Proceedings of the National ...
Phys.org / Third time's the charm for a row of faint galaxies without dark matter
A Yale-led team of astronomers has found a third galaxy devoid of dark matter—located alongside the other two in a formation that has never been seen before. Astronomers have followed a faint, cosmic trail of gas to a third ...
Phys.org / Why just sharing a stick while walking can significantly improve balance
Could the secret to preventing dangerous falls be surprisingly simple? For older adults, these unexpected tumbles are a leading cause of injury, affecting roughly 1 in 4 people 65 and older each year. What if the key isn't ...
Tech Xplore / Human understanding of AI can't keep up with its advancement, researchers say
In a recent editorial published in Science, Microsoft's chief scientific officer, Eric Horvitz, and researcher Robert West from the School of Computer and Communication Sciences at EPFL in Switzerland issue a stark warning ...
Phys.org / Could Earth have sent life to Jupiter's moon Europa?
Could Earth have seeded Jupiter's moon Europa with bacterial life, where it could have taken hold in Europa's ocean and perhaps evolved into something more? That's the hypothesis of a new paper in the International Journal ...
Phys.org / Powerful UFO spotted blasting from a distant black hole
Astronomers have detected one of the most powerful ultra-fast outflows ever seen from a distant supermassive black hole. Using XMM-Newton and NuSTAR, a team studied a hyper-luminous quasar at cosmic noon and found two distinct ...
