This is the only solely ion propelled series of aircrafts that can lift their power supplies against earth’s gravity. These prototypes were patented specifically for lifting their onboard power supplies and the widely published patent has been in effect since 2014.

While the craft wasn’t working at full power for this test footage since their was a power loss, the safety tether still went completely loose when the craft was energized, and it is also shown flying outdoors. There is an indoor flight that lasted for almost 2 minutes continually when it was flying at its best. There is a video of that and other sustained flights on this YouTube channel.

Previously all heavier than air ion propelled aircrafts had to be connected through thin wires to large heavy power supplies that remained fixed to the ground.

This series of prototypes have been independently verified to fly with onboard power since 2006. It was necessary to increase the EAD thrust to weight ratio by several orders of magnitude as well as other upgrades to get it operational.

“The axons of nerve cells function a bit like a railway system, where the cargo is essential components required for the cells to survive and function. In neurodegenerative diseases, this railway system can get damaged or blocked,” Tasneem Khatib, the study’s first author, explained in a statement. “We reckoned that replacing two molecules that we know work effectively together would help to repair this transport network more effectively than delivering either one alone, and that is exactly what we found.”

Most neurodegenerative diseases are caused by multiple genetic abnormalities, making them difficult to address with gene therapy targeted at single mutations. Astellas is working on a gene therapy that expresses two proteins, and a University of Cambridge team has shown that it holds promise in glau…

Harvard University researchers have identified the biological mechanism of how chronic stress impairs hair follicle stem cells, confirming long-standing observations that stress might lead to hair loss.

In a mouse study published in the journal Nature, the researchers found that a major stress hormone causes to stay in an extended resting phase, without regenerating the follicle and hair. The researchers identified the specific cell type and molecule responsible for relaying the stress signal to the stem cells, and showed that this pathway can be potentially targeted to restore hair growth.

“My lab is interested in understanding how stress affects stem cell biology and tissue biology, spurred in part by the fact that everyone has a story to share about what happens to their skin and hair when they are stressed. I realized that as a skin stem cell biologist, I could not provide a satisfying answer regarding if stress indeed has an impact—and more importantly, if yes, what are the mechanisms,” said Ya-Chieh Hsu, Ph.D., the Alvin and Esta Star Associate Professor of Stem Cell and Regenerative Biology at Harvard and senior author of the study. “The skin offers a tractable and accessible system to study this important problem in depth, and in this work, we found that stress does actually delay stem cell activation and fundamentally changes how frequently hair follicle stem cells regenerate tissues.”

In a first, scientists have revealed that animal and human DNA can be plucked straight out of thin air. The development heralds a promising new scientific technique with possible applications for ecology, forensics, and medicine, according to a new study.

“For example, this technique could help us to better understand the transmission of airborne diseases such as COVID-19.”

The research team is working with partners in industry, including the company NatureMetrics, to see how the technique can be applied in other ways, the university said.

A U.S. startup combined radioactive isotopes from nuclear waste with ultra-slim layers of nanodiamonds to assemble a ridiculous battery that allegedly can last 28000 years.

According to the California startup in question, called NDB (Nano Diamond Battery), their product is a “high-power diamond-based alpha, beta, and neutron voltaic battery.”

The energy comes from waste graphite that was previously used in graphite-cooled nuclear reactors. The radioactive graphite is encased in layers of nano-thin, single crystalline diamond, which act both as a semiconductor and heat sink.

Brown University is facing a cyberattack that has forced the school to shut some systems down — in an event that Brown is calling an “utmost priority.”

Jack Wrenn, a fifth-year doctoral candidate, said that official information was still “frustratingly scant” as of Wednesday night.

Wrenn provided a timeline as to what he understood transpired, and when the university community was notified.

European automaker Renault debuted its new cheap electric cars, the Kwid series, in India for a little over $6000 USD. The incredibly low price has left many consumers wondering why certain counties have access to cheap EV cars, while buyers in Europe and the United States are expected to pay more than quadruple that price for similar vehicles. It turns out there is a conspiracy and Europeans and North Americans who want electric cars are getting gouged by automakers, and it all has to do with gaining access to new markets.

The Kwid specifications are nearly identical to a Dacia, also a Renault brand. The difference: a European Dacia is double the price of an Indian Kwid. Meanwhile, the U.S. market misses entirely on either of these vehicles. The only electric cars available in America are dominated by premium brands and high price tags, making them unaffordable for most.

Cheap electric cars are available. The question is, why are Americans and Europeans being ripped off by electric vehicle manufacturers?
