Periodic pattern consisting of magnons is formed at room temperature. A team of researchers has succeeded in creating a micrometer-sized space-time crystal consisting of magnons at room temperature. With the help of an ultra-precise X-ray microscope, they were able to capture the recurring periodic magnetization structure in a movie. [embedded content]A space time crystal formed […]

Dreams take us to what feels like a different reality. They also happen while we’re fast asleep. So, you might not expect that a person in the midst of a vivid dream would be able to perceive questions and provide answers to them. But a new study reported in the journal Current Biology on February […]
Read MoreThe Perseverance Mars rover’s “sky crane” descent stage made the ultimate sacrifice last week, and we now have a photo to memorialize the flying robot’s heroic death. The rocket-powered sky crane lowered the car-sized Perseverance rover to the floor of Mars’ Jezero Crater on cables last Thursday (Feb. 18), bringing the rover’s harrowing “seven minutes […]

Beyond Earth, the general scientific consensus is that the best place to search for evidence of extraterrestrial life is Mars. However, it is by no means the only place. Aside from the many extrasolar planets that have been designated as “potentially-habitable,” there are plenty of other candidates right here in our Solar System. These include […]

How long-chain molecules are formed. Credit: © LMU LMU physicists demonstrate that fundamental characteristics of polymeric molecules, such as their subunit composition, are sufficient to trigger selection processes in a plausible prebiotic setting. Before life emerged on Earth, many physicochemical processes on our planet were highly chaotic. A plethora of small compounds, and polymers of […]
Read MoreNASA’s Perseverance rover has given us our best view yet of its Martian landing site. The car-sized Perseverance captured a gorgeous 360-degree panorama of its surroundings on the floor of Jezero Crater, which harbored a lake and a river delta billions of years ago. The photo, which NASA released today (Feb. 24), is composed of […]

Read MoreNearly five millennia ago, an artist inked an incredibly detailed painting of geese in the tomb of an Egyptian vizier and his wife. This “Mona Lisa” of ancient Egypt may depict a previously unknown and now extinct species of goose, a new analysis suggests. The 4,600-year-old painting, known as “Meidum Geese,” was discovered in the […]

While some people slather mayonnaise on their sandwiches, Israel’s National Sea Turtle Rescue Center uses the condiment for a unique purpose: to treat endangered turtles after oil spills, The Associated Press (AP) reported. More than 100 miles (160 kilometers) of Israel’s Meditteranean coastline became blotted with huge globs of tar last week, after an oil […]

Binary star systems are everywhere. They make up a huge percentage of all known solar systems: from what we can tell, about half of all Sun-like stars have a binary partner. But we haven’t really had a chance to study them in detail yet. That’s about to change. Using data from the European Space Agency’s […]
