A Tennessee teen has become the youngest person in America—and possibly the world—to build a working nuclear reactor and achieve fusion.

Jackson Oswalt, now 14, set out on the ambitious project when he was just 12, according to USA Today, and achieved nuclear fusion in his Memphis home just hours before he turned 13 on Jan. 19, 2018.

“A couple of years back, all I did was play video games,” he told the news outlet. “And I decided I didn’t want to spend all my life doing video games.”

The manuscript had amassed more than about problematic figures and data on PubPeer.

During the pre-vaccination years, people died at younger ages not only because of poor sanitation and hygiene, but also mostly due to these 14 fatal diseases.

NASA and commercial crew provider SpaceX are targeting 2:48 a.m. EST Saturday, March 2, for the launch of the Demo-1 uncrewed flight test to the International Space Station. The uncrewed test flights will be the first time a commercially-built and operated American rocket and spacecraft designed for humans will launch to the space station.

Live coverage will begin on NASA Television and the agency’s website Friday, Feb. 22 with prelaunch events.

The SpaceX Crew Dragon spacecraft will launch on a Falcon 9 rocket from the historic Launch Complex 39A at NASA’s Kennedy Space Center in Florida. About 10 minutes after launch, Crew Dragon will reach its preliminary orbit. It is scheduled to dock to station Sunday, March 3 at 5:55 a.m. ESThe Crew Dragon spacecraft will carry about 400 pounds of crew supplies and equipment to the space station and return some critical research samples to Earth.

Researchers at the Salk Institute have moved a step closer to a possible therapy for Hutchinson-Gilford progeria syndrome, a rare genetic disorder that is often described as accelerated aging, as people with it appear to age far faster than normal. Using a new CRISPR/Cas9 gene therapy in a mouse model, they were able to slow down the pace of the condition, improve health, and increase lifespan.

What is Hutchinson-Gilford progeria?

Progeria is a degenerative disorder caused by a mutation in the LMNA gene. This disease has an early onset and progresses rapidly, and animals and humans with progeria show symptoms that are similar to regular aging, only on a much-accelerated timescale, giving them drastically shorter lifespans than normal. Humans with this condition rarely live very long, with the average being only 13 years old.

“Paul and Laura have made huge contributions to the biomedical gerontology field in recent years. Their work focuses on the characterisation and alleviation of the aspects of aging that are driven by DNA damage. At UA2019, their talks will describe their recent advances in the mechanistic understanding of DNA damage, aided by spectacularly good mouse models, and also their identification of natural products with potent senolytic activity”, says Aubrey de Grey.

The basics of heart health have been drilled into our brains: Eat less saturated fat. Keep moving. Know your “numbers” for cholesterol, blood pressure and BMI.

But what about that brain itself? Although life expectancy has more than doubled since 1900, our “mindspan” — how long we stay cognitively healthy — hasn’t kept pace.
