Using nasal cartilage cells to repair joints is nothing to sniff at.
It has worked in goats. And now, in the first human trial, researchers at the University of Basel have taken the cells, called chondrocytes, from the noses of 10 patients with damaged knee joints and grown them into cartilage grafts. These repair patches were then surgically implanted into the patients' knee joints....

Clever chemistry could take the salt out of water softening.
Aluminum ions can strip minerals from water without the need for sodium, researchers report online October 4 in Environmental Science & Technology. The new technique could sidestep health and environmental concerns raised about the salt released by existing sodium-based water softening systems, says study coauthor Arup...
Screens are everywhere. They adorn walls, perch on the backs of car seats and warm our hands. No one knows yet whether all of these screens, and their alluring displays and connections to the world, have any long-term effects on us. There is one group of people, though, for whom these ever-present screens may be particularly worrisome — kids.
Earlier recommendations on children’s screen...
VANCOUVER — Traces of long-lost human cousins may be hiding in modern people’s DNA, a new computer analysis suggests.
People from Melanesia, a region in the South Pacific encompassing Papua New Guinea and surrounding islands, may carry genetic evidence of a previously unknown extinct hominid species, Ryan Bohlender reported October 20 at the annual meeting of the American Society of...

Crucial immune system proteins that make it harder for viruses to replicate might also help the attackers avoid detection, three new studies suggest. When faced with certain viruses, the proteins can set off a cascade of cell-to-cell messages that destroy antibody-producing immune cells. With those virus-fighting cells depleted, it’s easier for the invader to persist...

PASADENA, Calif. — Jupiter’s clouds have deep roots. The multicolored bands that wrap around the planet reach hundreds of kilometers down into the atmosphere, NASA’s Juno spacecraft reveals, providing an unprecedented peek into the giant planet’s interior.
“Whatever’s making those colors and stripes still exists pretty far down,” planetary scientist Scott Bolton, head of the Juno mission...
Most of us spend our careers trying to meet — and hopefully exceed — expectations. Scientists do too. But the requirements for success in a job in academic science don’t always line up with the best scientific methods. The net result? Bad science doesn’t just happen — it gets selected for.
What does it mean to be successful in science? A scientist gets a job and funding by publishing a...

Maps have long been used to show the animal kingdom’s range, regional mix, populations at risk and more. Now a new set of maps reveals the global distribution of genetic diversity.
“Without genetic diversity, species can’t evolve into new species,” says Andreia Miraldo, a population geneticist at the Natural History Museum of Denmark in Copenhagen. “It...
Spring brings blooms, and not just on land. Warmer waters spur growth of a tiny ocean-dwelling bacteria. More than 10 years of data collected at an unusually high-tech ocean observatory reveal that the speedy growth of the phytoplankton Synechococcus is driven by an uptick in temperature. As spring’s warmth comes earlier, so does the phytoplankton’s annual growth spurt, resulting in a shift in...
A titanic volcano stopped a mega-sized earthquake in its tracks.
In April, pent-up stress along the Futagawa-Hinagu Fault Zone in Japan began to unleash a magnitude 7.1 earthquake. The rupture traveled about 30 kilometers along the fault until it reached Mount Aso, one of Earth’s largest active volcanoes. That’s where the quake met its demise, geophysicist Aiming Lin of Kyoto University...
