A site where 37,000 years ago a mammoth mother and her cub met their end offers some of the best evidence for humans settling in North America much earlier than conventionally thought. Bones from the abattoir record how humans shaped chunks of their long bones into disposable knives to break up their carcasses, and make their fat over fires. But a key detail sets this site apart from others from this era. That’s in New Mexico—a place where most archaeological evidence doesn’t locate humans until tens of thousands of years later. Researchers reveal a wealth of evidence that is rarely found in one place. These include fossils with blunt force fractures, bone-chilling blades with worn edges, and signs of a controlled fire. And thanks to carbon-dating analysis of collagen extracted from mammoth bones, the site also dates from 36,250 to 38,900...

The moon could be a huge rocket swap and a stopping point for humans to travel to other parts of the solar system in 2069 – the 100th anniversary of the first moon landing. This month marks 53 years since humanity made the giant leap and NASA’s Apollo 11 mission placed US astronauts Neil Armstrong and Buzz Aldrin on the surface of the brightest satellite on Earth. Now space scientists around the world are considering how the moon could become a “changeable” launch pad for the next half century.

Currently, scientists are trying to calculate whether it is possible to put a space station into orbit around the moon, with a view to sending people to Mars or even further into space. “I think that will be the future. Our next step from Earth is to figu...

Octa-glove takes an underwater Virginia Tech playing card from Michael Bartlett’s lab. Credit: Virginia Tech A research team led by Michael Bartlett of Virginia Tech has developed an octopus-inspired glove that can safely grip objects underwater. Their research was selected for the July 13 cover Science Advances . Humans are not naturally equipped to thrive in an underwater environment. We use tanks to breathe, neoprene clothing to protect and warm us, and glasses to see clearly. In such an environment, human hands are also not well equipped to hold things. Anyone who has tried to hold a wriggling fish will testify that underwater objects are difficult to grip with our land-dwelling fingers. “There are critical moments when this becomes mandatory,” said Bartlett, an assistant professor in the department of mechanical engineering. “Nature already has some great solutions, so...

A research team led by Michael Bartlett of Virginia Tech has developed an octopus-inspired glove that can safely grip objects underwater.

Anyone who has tried to hold a wriggling fish will testify that underwater objects are difficult to grip with our land-dwelling fingers. “There are critical moments when this becomes mandatory,” said Bartlett, an assistant professor in the department of mechanical engineering. “Nature already has some great solutions, so our team looks to the natural world for ideas. Octopus being the obvious choice for inspiration.” Rescue divers, underwater archaeologists, bridge engineers, and rescue crews all use their hands...

The researchers definitively linked the function of a protein-specific domain important in plant microbial biology to cancer triggers in humans, knowledge that scientists have avoided for decades. Team findings, published in natural Communication Biology, opens new avenues for the development of selective drug therapies to fight various types of cancer, such as cancers that start in the breast and stomach. ORNL scientists set out to experimentally prove what they first concluded with a computational study: that the plasminogen-apple-nematode, or PAN, domain is associated with cell proliferation that promotes tumor growth in humans and defense signaling during plant-microbial interactions in plant-bioenergy. plant. This association was first made when researchers were exploring the genomes of plants such as poplars and willows.
