Scientists have figured out how to make frozen discs of ice self-propel across a patterned metal surface, according to a new paper published in the journal ACS Applied Materials and Interfaces. It’s the latest breakthrough to come out of the Virginia Tech lab of mechanical engineer Jonathan Boreyko. A few years ago, Boreyko’s lab experimentally demonstrated a three-phase Leidenfrost effect …

A recent discovery by a team of astronomers centres on a galaxy cluster called CHIPS 1911+4455, located an incredible 6 billion light-years from Earth. At its heart lies a supermassive black hole that has only recently ‘turned on’, just a thousand years ago. While that might sound like a long time, it’s merely a blink of an eye in astronomical …

Light and lifting The researchers then built a few sheets of nanocardboard to test the output of their model. The actual products, primarily made of chromium, aluminum, and aluminum oxide, were incredibly light, weighing only a gram for a square meter of material. When illuminated by a laser or white LED, they generated measurable force on a testing device, provided …

The idea of taking blood from the young to rejuvenate the elderly is getting an increasing amount of attention from scientists, and a new study has shown how some of the youthful properties of our skin can be restored with this kind of blood swap. A special 3D human skin model was set up in the lab by researchers, who …

The red-headed wood pigeon, found only on Japan’s remote Ogasawara Islands, has staged an incredible recovery from the early 2000s, when the bird’s numbers fell to fewer than 80 individuals. The turning point came when conservationists removed feral cats, which, since being introduced to the islands, had been preying on the red-headed wood pigeons (Columba janthina nitens). The population rebounded …

Many suspect that California’s San Andreas Fault is brewing yet another major earthquake. However, it might not necessarily play out as scientists thought it would – just look at the recent disaster in Myanmar. In a new study, researchers from the California Institute of Technology took a close look at the Mw7.7 Mandalay earthquake that caused havoc through Myanmar, Southeast …

NEW YORK (AP) — Six planets are hanging out in the sky this month in what’s known as a planetary parade. Catch the spectacle while you can because it’s the last one of the year. These linkups happen when several planets appear to line up in the night sky at once. Such parades are fairly common, happening around every year …
