Changes in Sperm RNA May Shape Future Generations, Scientists Warn

Posted by in categories: biotech/medical, ethics, satellites

While the rest of the world debates the ethics of designer babies, a team at the University of Massachusetts Medical School (UMass) have shown that we might not need CRISPR to change the genes of future generations. Their paper, released this week in the journal Developmental Cell, shows that things like diet and stress might affect some crucial genetic components of sperm, and that these tiny changes have real effects on how babies develop.

The same way rockets bound for outer space contain “payloads” like satellites, or astronauts who battle giant balls of urine, sperm are also like little rockets containing their own cargo: “small RNAs.” This study found that not only do RNA sequences play a crucial role in how genes get expressed early on in human development, but they can also be radically changed by the lifestyles of fathers. Things like diet, and in particular, stress can change the makeup of this crucial RNA cargo and lead to observable changes in offspring, says researcher Colin Conine, Ph.D., at UMass Medical School’s Rando Lab.

“Labs all over the world have been able to link changes in dad’s lifestyle to changes in RNA in the sperm, and then that leads to phenotypes in the offspring,” Conine tells Inverse. “Our study was one of the first to really look at how changes small RNAs affect early development. We wanted to ask, what are the first steps that lead to these phenotypes down the road?”

Satellite startups turn to reinventing broadband, mapping and other industries

Posted by in categories: computing, mapping, mobile phones, satellites

Smartphones have disrupted transportation, payments and communication. But the underlying technology has tangentially changed a completely different sector: satellites.

The advances made in miniaturizing technologies that put a computer in your pocket — cameras, batteries, processors, radio antennas — have also made it easier and cheaper for entrepreneurs to launch matter into space. And investors are taking notice.

The chart below shows worldwide venture and PE investment in satellite technology companies.

Giant Satellite Fuel Tank Sets New Record for 3D Printed Space Parts

Posted by in categories: 3D printing, energy, satellites

DENVER, July 11, 2018 /PRNewswire/ — Lockheed Martin (NYSE: LMT) has embraced a 3D printed titanium dome for satellite fuel tanks so big you can’t even put your arms around it. The 46-inch- (1.16-meter-) diameter vessel completed final rounds of quality testing this month, ending a multi-year development program to create giant, high-pressure tanks that carry fuel on board satellites.

A Lockheed Martin engineer inspects one of the 3D printed dome prototypes at the company's space facility in Denver. The final dome measures 46 inches in diameter, large enough to fit 74.4 gallons of liquid.

The titanium tank consists of three parts welded together: two 3D printed domes that serve as caps, plus a variable-length, traditionally-manufactured titanium cylinder that forms the body.

Earth Views from the Space Station

Behold, the Earth! See live views of Earth from the coming to you by NASA’s High Definition Earth Viewing (HDEV) experiment.


Behold, the Earth! See live views of Earth from the International Space Station coming to you by NASA’s High Definition Earth Viewing (HDEV) experiment.

While the experiment is operational, views will typically sequence through the different cameras. If you are seeing a black image, the Space Station is on the night side of the Earth. If you are seeing an image with text displayed, the communications are switching between satellites and camera feeds are temporarily unavailable. Between camera switches, a black & gray slate will also briefly appear.

The rockets that are pushing the boundaries of space travel

Posted by in category: satellites

Friday morning at 5:24 am (0924 GMT), a rocket owned by the US company SpaceX will blast off from Florida carrying two and a half tons of gear from NASA, only to dock three days later and 250 miles (400 kilometers) above Earth at the International Space Station.

The itself is not new. It launched a NASA satellite into orbit two months ago, then landed back on Earth—upright—on a barge in the Atlantic Ocean off Cape Canaveral.

Even the Dragon capsule, carrying the cargo and affixed to the top of the rocket was used before, having flown a mission to the ISS in 2016.
