Conventional wisdom tells us that large objects appear smaller as they get farther from us, but this fundamental law of classical physics is reversed when we observe the distant universe. Astrophysicists at Kent simulated the development of the biggest objects in the universe to help explain how galaxies and other cosmic bodies were formed. By looking ...
Fire starting is a skill that many modern humans struggle with in the absence of a lighter or matches. The earliest humans likely harvested fire from natural sources, yet when our ancestors learned the skills to set them at will, they had newfound protection, a means of cooking, light to work by, and warmth at ...
The flooding from torrential rains caused by cyclones and monsoonal storms, as well as other catastrophic events, is responsible for moving huge amounts of trees to a watery grave deep under the ocean, according to Earth scientists. Their research, published in the Proceedings of the National Academy of Sciences, shows the first-ever evidence that trees may ...
Candidates at job interviews expect to be evaluated on their experience, conduct, and ideas, but a new study by Yale researchers provides evidence that interviewees are judged based on their social status seconds after they start to speak, a form of bias in hiring. The study, to be published in the Proceedings of the National ...
Australian creatures like the echidna and the koala are celebrated for their oddness. The fossil record shows that these oddities reach far back into prehistory, as illustrated in the form of a fossil horseshoe crab found in Tasmania that has been renamed by UNE paleontologist Dr. Russell Bicknell, saying: “The specimen from the Upper Permian ...
A study finds that even the tallest ice cliffs should be able to support their weight rather than collapse catastrophically. The Antarctic ice sheet spans close to twice the area of the contiguous United States, and its land boundary is buttressed by massive, floating ice shelves extending hundreds of miles out over the frigid waters ...
A new study led by Yale University confirms a long-held theory about the last great mass extinction event in history and how it affected Earth’s oceans. The findings may also answer questions about how marine life eventually recovered. The researchers say it is the first direct evidence that the Cretaceous-Paleogene extinction event 66 million years ...
Just like the Moon orbits the Earth, and the Earth orbits the Sun, galaxies orbit each other according to the predictions of cosmology. For example, more than 50 discovered satellite galaxies orbit our own galaxy, the Milky Way. The largest of these is the Large Magellanic Cloud, or LMC, a large dwarf galaxy that resembles a ...
A NASA team uses supercomputing to evaluate a retropropulsion-powered descent to the Martian surface for a Mars landing. The type of vehicle that will carry people to the Red Planet is shaping up to be “like a two-story house you’re trying to land on another planet. The heat shield on the front of the vehicle ...
An international team of astronomers, led by the University of Southampton, has used state-of-the-art cameras to create a high frame-rate movie of a growing black hole system at a level of detail never seen before. In the process, they uncovered new clues to understanding the immediate surroundings of these enigmatic objects. The scientists published their work ...
