Bones
-
Thanks to a new understanding of how bones maintain their strength, we may someday see bone-inspired materials used in longer-lasting products such as aircraft wings. The findings could also lead to better treatments for conditions like osteoporosis.

Archaeologists in Ecuador have made a fascinating and grisly discovery. In a burial mound dating back 2,100 years, the scientists found signs of a ritual never seen before – two babies buried wearing “helmets” made of the skulls of other children.
-
An almost-complete skull of Australopithecus anamensis allowed scientists to realistically recreate its face for the first time.
-
SciencePalaeontologists in New Zealand have now uncovered the remains of Heracles inexpectatus, an extinct giant parrot that would have stood hip-high to most people and packed a beak powerful enough to crack open pretty much whatever it wanted to.

Red wine may have health benefits against cancer, obesity, aging, and even cavities. Now, a new study may add muscle loss to the list. In tests on rats, a Harvard team found that a red wine compound called resveratrol could help keep astronauts toned during trips in space or life on Mars.

ScienceFossilized human skulls found in a cave in Greece may force a rewrite of the human migration timeline yet again. Archaeologists have dated one of the skulls to about 210,000 years old – roughly 150,000 years older than the previous record-holder for earliest modern human remains in Europe.

Space travel is conducive to injuries. Now researchers from Dresden Technical University (TUD) have developed a 3D bioprinting method for use in space, creating new skin and bone tissue out of resources that might be available to astronauts.

ScienceAh, eggshells … they could already find use in eco-friendly rubber, carbon capture, ceramics, biodegradable packaging, and energy storage. Now, new research shows that the ubiquitous form of food waste may also be utilized to grow bone for use in transplants.
-
ScienceGenerally speaking, the animals alive today are mere shadows of their former selves, and birds were no exception. In a Crimean cave, palaeontologists have uncovered the bones of some of the most gigantic birds to have ever walked the Earth, that would have lived alongside early European humans.

When someone is missing facial bone due to injury or illness, the current treatment involves transplanting a piece of bone extracted from the leg, leaving a deficit there. Now, however, scientists have succeeded in growing extra bone within sheep's bodies, that's preformed to the shape required.
-
ScienceImprints of ancient bones or footprints are often found in rock, but that’s not the only way they form – in much rarer cases they can also be encased in opal. Now palaeontologists in Australia have uncovered the most complete “opalized” dinosaur, which also happens to be a new species.

It’s not known exactly when humans and Neanderthals split off from their last common ancestor, but the estimated window is very wide, between 300,000 and 800,000 years ago. Now a new study has found evidence that this split took place towards the earlier end of that range, or even longer ago still.
