Universal formula for cosmic voids A simple equation can describe the large-scale bubbles that appear in the dark matter distributed throughout the Universe, and it applies to voids of a wide range of sizes and ages. Physics Bone-house wasps use ant carcasses to build nests for their young Deuteragenia ossarium, or the bone-house wasp, is […]

Looks like a mouse but is genetically related to elephants A tiny, long-nosed creature found in western Africa looks like a mouse, but is genetically closer to an elephant, according research published in the Journal of Mammalogy. Biologists who discovered the new species of elephant shrew call it Macroscelides micus. It lives in an ancient […]

Hidden portrait lies behind Picasso’s “Blue Room” Scientists using infrared technology have revealed a portrait of a bearded man resting his head on his hand underneath Pablo Picasso’s 1901 painting “The Blue Room.” Picasso often reused canvasses because he couldn’t afford new ones, according to art experts. Two years ago, another portrait was found underneath […]

Identified a new type of stone formed by plastic Discarded plastic has created a new type of stone, mixed with other materials, both natural and manufactured. The strange plastiglomerate formations were first discovered in 2006 on a polluted beach area in a remote part of Hawaii’s Big Island, but the significance of the find wasn’t […]

Handwriting is key for educational development Handwriting is starting to fade from the curriculum of many schools, but experts say the practice is important for educational development. The New York Times Superbugs use genetic material as cloak to avoid detection A deadly class of antibiotic-resistant bacteria called carbapenem-resistant Enterobacteriaceae, carries genetic material that serves as […]

Orb-web spiders craft a unique disguise An orb-web spider hides itself from predators by disguising itself as bird droppings, according to researchers. The spiders have a silver colored body that, when combined with their white disc-shaped webs, gives the illusion of bird excrement that may deter predatory wasps. LiveScience Ants are organized searchers who gain […]

Study of extinct elephant bird leads researchers to surprising conclusion DNA studies of the massive, extinct elephant bird of Madagascar show that its closest modern relative is New Zealand’s tiny kiwi, rather than the ostrich, which it more closely resembles, leading researchers to speculate about how the flightless birds migrated, according to a study published […]

Plant that consumes nickel found in the Philippines A plant that thrives in nickel-rich dirt has been discovered in the Philippines. Rinorea niccolifera can absorb large amounts of nickel through its leaves. UPI Regrown bone in monkeys using pluripotent stem cells It could be possible to grow new bone in humans using induced pluripotent stem […]

Turtles more closely related to crocodiles and birds than snakes and lizards The murky evolutionary history of the turtle has been made a little clearer by researchers using new microRNA data which link the shelled reptiles more closely with birds and crocodiles than to lizards and snakes. Yale University Universe’s evolution recreated in computer simulation […]

Wet sand may have helped ancient Egyptians move massive stones Ancient Egyptians dampened the sand to move the 2.5-ton stones used to build the pyramids to prevent berming and halve the amount of force needed to drag the sled, researchers say. The wet sand reduced the friction, making the sledge easier to move. Scientists at […]
