Good News: Soil Could Be a Much Larger Carbon Sink Than We Hoped

Soil minerals just a little way underground could act as a huge carbon sink to help balance out the dangerous levels of carbon dioxide in our atmosphere, according to new research.

If we can tap into its potential to suck even more carbon pollution out of the air, it would be a massive advantage.

Outrage after Kyrgyzstan reburies its only ancient mummy

Scientists have called for Kyrgyzstan’s only mummy to be immediately dug back up after the 1,500-year-old relic was taken from a museum and hastily reburied on the eve of a presidential election in a decision celebrated by self-professed psychics.

The female mummy was put back in the ground in mid-October in the same dusty corner of southern Kyrgyzstan where it was discovered in 1956 after a sudden ruling by a state commission.

The decision was made despite strong opposition from the only archaeologist on the commission and culture minister Tugelbai Kazakov, who played the decisive role in the call, resigned on Saturday. 

Kazakov said the mummy had been largely neglected by scientists and the country lacked the finances to keep it in good condition. Read more.

AI-controlled brain implants for mood disorders tested in people 

Brain implants that deliver electrical pulses tuned to a person’s feelings and behaviour are being tested in people for the first time. Two teams funded by the US military’s research arm, the Defense Advanced Research Projects Agency (DARPA), have begun preliminary trials of ‘closed-loop’ brain implants that use algorithms to detect patterns associated with mood disorders. These devices can shock the brain back to a healthy state without input from a physician.

The work, presented last week at the Society for Neuroscience (SfN) meeting in Washington DC, could eventually provide a way to treat severe mental illnesses that resist current therapies. It also raises thorny ethical concerns, not least because the technique could give researchers a degree of access to a person’s inner feelings in real time.

The general approach — using a brain implant to deliver electric pulses that alter neural activity — is known as deep-brain stimulation. It is used to treat movement disorders such as Parkinson’s disease, but has been less successful when tested against mood disorders. Early evidence suggested that constant stimulation of certain brain regions could ease chronic depression, but a major study involving 90 people with depression found no improvement after a year of treatment.1

The scientists behind the DARPA-funded projects say that their work might succeed where earlier attempts failed, because they have designed their brain implants specifically to treat mental illness — and to switch on only when needed. “We’ve learned a lot about the limitations of our current technology,” says Edward Chang, a neuroscientist at the University of California, San Francisco (UCSF), who is leading one of the projects.

Christopher Columbus: What Really Happened

A Helium-Resistant Material Could Finally Usher in The Age of Nuclear Fusion

"We were blown away by what we saw."

A collaboration of engineers and researchers has found a way to prevent helium, a byproduct of the fusion reaction, from weakening nuclear fusion reactors.

The secret is in building the reactors using nanocomposite solids that create channels through which the helium can escape.

Researchers from Texas A&M University, working with a team from the Los Alamos National Laboratory in New Mexico, have tested a new method for creating the materials used in nuclear fusion reactors and found that it could eliminate one of the obstacles preventing humanity from harnessing the power of fusion energy.
