Summary: NIH researchers have identified a specific type of sensory neurons which become activated as a result of pulling a single hair.

Researchers from the National Institutes of Health have identified a class of sensory neurons (nerve cells that electrically send and receive messages between the body and brain) that can be activated by stimuli as precise as the pulling of a single hair. Understanding basic mechanisms underlying these different types of responses will be an important step toward the rational design of new approaches to pain therapy. The findings were published in the journal Neuron.

Scientists have discovered for the first time that adult mouse brains produce new cells in the amygdala, a finding that could eventually lead to better treatments for conditions like anxiety and depression, as well as a better understanding of the brain overall.

The amygdala handles a lot of our emotional responses, especially those relating to fear, and broken connections inside it can lead to anxiety disorders such as post-traumatic stress disorder (PTSD).

If the brain is capable of regenerating neurons in the amygdala, then that’s potentially one way of fighting back against these mental health issues, according to the team from the University of Queensland in Australia.

Forever Labs, a startup in Y Combinator’s latest batch, is preserving adult stem cells with the aim to help you live longer and healthier.

Stem cells have the potential to become any type of cell needed in the body. It’s very helpful to have younger stem cells from your own body on hand should you ever need some type of medical intervention, like a bone marrow transplant as the risk of rejection is greatly reduced when the cells are yours.

Mark Katakowski spent the last 15 years studying stem cells. What he found is that not only do we have less of them the older we get, but they also lose their function as we age. So, he and his co-founders Edward Cibor and Steve Clausnitzer started looking at how to bank them while they were young.

In a recent study, Stanford scientists were able to transfer electricity wirelessly to a moving lightbulb. The technology they developed help overcome the limited driving range of electric cars, currently one of their biggest drawbacks.

If electric cars could recharge while driving down a highway, it would virtually eliminate concerns about their range and lower their cost, perhaps making electricity the standard fuel for vehicles.

Who wouldn’t want to have breakfast on the French Riviera, take a walk along the Great Wall of China in the afternoon, and then cap off the evening by staring at stars above the Alaskan wilderness? That fantastic day might be possible soon, thanks to British aerospace firm Reaction Engines Limited (REL). The company is working on an aircraft that will be able to transport passengers anywhere in the world in just four hours.

Yes. That’s four hours.

The technology furor that has emerged way before 2014, and swept across the country can’t be more pronounced. As many as 17 national-level innovation demonstration zones from coastal Shenzhen to inland Chengdu city have been handpicked by the State Council, or China’s cabinet, and allowed to offer favourable policies to spur innovation and drive regional economic growth based on their respective strengths and geographical advantages.

Beijing has picked 17 tech hubs across the country to transform from a manufacturing-reliant economy to one led by tech and innovation.

China’s five year plan to eliminate birth defects by preimplantation genetic diagnosis of embryos.

Gene-editing with CRISPR has been in the headlines over the past month and touted as a way of eliminating genetic diseases. But the cruder and cheaper technique of preimplantation genetic diagnosis does the same. And it is exploding in China. According to a feature in Nature, fertility doctors there “have been pursuing a more aggressive, comprehensive and systematic path towards its use there than anywhere else”.

The government’s current five-year plan for economic development has made reproductive medicine, including PGD, a priority. In 2004, only four clinics in the whole country were licensed to perform PGD; now there are 40.
