Woah.

In a new video released by jetpack maker Gravity Industries, a jetsuit-wearing special ops soldier from the Netherlands Maritime Special Operations Force can be seen boarding a ship — by flying there from a nearby pursuit vessel.

It’s a spectacular demonstration of Gravity Industries’ flying technology. Rather than having to pursue and approach the ship in the tailing vessel, the jetpack-enhanced soldier simply takes to the skies and effortlessly lands on the deck of the ship — in a fraction of the time boarding would have taken otherwise.

Gravity has quickly emerged as one of the biggest players in the jetpack field over the last few years, offering its jetsuit technologies to first responders and military forces around the world. It has even allowed journalists to give the suit a test drive, albeit with safety tethers.

In the weeks following its launch in early 2006, when NASA ’s New Horizons was still close to home, it took just minutes to transmit a command to the spacecraft, and hear back that the onboard computer received and was ready to carry out the instructions.

As New Horizons crossed the solar system, and its distance from Earth jumped from millions to billions of miles, that time between contacts grew from a few minutes to several hours. And on April 17 at 12:42 UTC (or April 17 at 8:42 a.m. EDT), New Horizons reached a rare deep-space milepost – 50 astronomical units from the Sun, or 50 times farther from the Sun than Earth is.

Here’s one way to imagine just how far 50 AU is: Think of the solar system laid out on a neighborhood street; the Sun is one house to the left of “home” (or Earth), Mars would be the next house to the right, and Jupiter would be just four houses to the right. New Horizons would be 50 houses down the street, 17 houses beyond Pluto!

Rejuvenate Bio’s treatment is a gene therapy that dials up expression of the genes sTGFbetaR2 and FGF21 to reduce levels of the cytokine TGF-beta1 and boost levels of the hormone FGF21, respectively. Both genes are associated with longevity.

“What we have seen from using a combination of two genes is the ability to affect multiple age-related diseases at once,” Oliver said.

Rejuvenate Bio published data in November 2019 showing that targeting these two genes in mice reduced kidney atrophy and reversed weight gain and Type 2 diabetes. The company had given extra copies of those genes, alone and in combination with each other and another gene called alpha-Klotho to see if they could boost the mice’s health and life spans. It found out that more isn’t necessarily better, as mice that were given all three genes together fared worse than the other animals did.

Liftoff is scheduled for Thursday, April 22.

CAPE CANAVERAL, Fla. — NASA has given SpaceX the official go-ahead for the launch of its next crew mission to the International Space Station.

That mission, called Crew-2, will blast off on a SpaceX Falcon 9 rocket at 6:11 a.m. EST (1011 GMT) on Thursday morning (April 22) from NASA’s historic Pad 39A and Kennedy Space Center in Florida. It will be the second flight of this particular Crew Dragon. The capsule, named “Endeavour,” first carried NASA astronauts Bob Behnken and Doug Hurley to and from the space station last year for the Demo-2 test flight.

Behind the scenes of the Electron-Ion Collider, green accelerators that waste no energy, and chiral magnetic effect results debuting this summer.

When the Electron Ion Collider received the go-ahead in January 2020, it became the only new major accelerator in the works anywhere in the world.

“All the stars aligned,” said Elke-Caroline Aschenauer, Brookhaven National Laboratory Staff Scientist and a leader in developing the EIC plans. “We have the technology to build this unique particle accelerator and detector to do the measurements that, together with the underlying theory, can for the first time provide answers to longstanding fundamental questions in nuclear physics.”

AI systems can lead to race or gender discrimination.

The US Federal Trade Commission has warned companies against using biased artificial intelligence, saying they may break consumer protection laws. A new blog post notes that AI tools can reflect “troubling” racial and gender biases. If those tools are applied in areas like housing or employment, falsely advertised as unbiased, or trained on data that is gathered deceptively, the agency says it could intervene.

“In a rush to embrace new technology, be careful not to overpromise what your algorithm can deliver,” writes FTC attorney Elisa Jillson — particularly when promising decisions that don’t reflect racial or gender bias. “The result may be deception, discrimination — and an FTC law enforcement action.”

As Protocol points out, FTC chair Rebecca Slaughter recently called algorithm-based bias “an economic justice issue.” Slaughter and Jillson both mention that companies could be prosecuted under the Equal Credit Opportunity Act or the Fair Credit Reporting Act for biased and unfair AI-powered decisions, and unfair and deceptive practices could also fall under Section 5 of the FTC Act.

Someday, scientists believe, tiny DNA-based robots and other nanodevices will deliver medicine inside our bodies, detect the presence of deadly pathogens, and help manufacture increasingly smaller electronics.

Researchers took a big step toward that future by developing a new tool that can design much more complex DNA robots and nanodevices than were ever possible before in a fraction of the time.

In a paper published on April 19, 2021, in the journal Nature Materials, researchers from The Ohio State University – led by former engineering doctoral student Chao-Min Huang – unveiled new software they call MagicDNA.
