First single molecule microscopic visualization of the full-length human BRCA2 protein binding to DNA

Posted by in categories: biotech/medical, genetics

Using a self-built inverted microscope complete with laser optical tweezers to capture DNA, Yale Cancer Center and University of California Davis researchers for the first time created a visualization of the full-length human BRCA2 protein at the single molecule level.

Mutations in the breast cancer susceptibility gene, BRCA2, can significantly increase an individual’s lifetime risk of developing cancer. Approximately one in every 400 people carry a BRCA gene mutation accounting for a significant proportion of cancer that is heritable. The study was published on March 28 in the Proceedings of the National Academy of Sciences.

“If you carry a BRCA mutation, you have this incredibly high risk for breast and , and also for men, prostate and ,” said Yale Cancer Center member and co-author of the paper, Ryan Jensen, Ph.D., who is also an associate professor of therapeutic Radiology at Yale School of Medicine.

Trojanized Tor browsers target Russians with crypto-stealing malware

Posted by in categories: cryptocurrencies, cybercrime/malcode

A surge of trojanized Tor Browser installers targets Russians and Eastern Europeans with clipboard-hijacking malware that steals infected users’ cryptocurrency transactions.

Kaspersky analysts warn that while this attack is not new or particularly creative, it’s still effective and prevalent, infecting many users worldwide.

While these malicious Tor installers target countries worldwide, Kaspersky says that most are targeting Russia and Eastern Europe.

Scientists Have Just Found An Untouched Civilization In The Amazon Jungle

Posted by in category: futurism

There are a number of places on earth that remain shrouded in mystery, despite the best efforts of scientists to explain them. Some of these places are locations where strange things have happened for centuries, while others are relatively new. But one thing is for sure – they all remain a mystery.

DARPA wants a Spec Ops plane with a set of insane characteristics — and it wants it fast

Posted by in category: transportation

It can take off vertically with a lead-up (defined as the length of runway needed for take-off) of less than 300 feet, hover in austere environments, and fly forward at more than 450 miles per hour. And, by the way, it’s probably a fixed-wing plane.

That, at least, is the idea behind DARPA’s SPRINT X-plane, a project in the beginning stages of development for use by the U.S. Special Operations Command (SOCOM). The Defense Advanced Research Projects Agency recently called for proposals for a plane with a mind-bending set of capabilities. According to the March solicitation, DARPA wants a scaled demonstrator ready to fly within the next three-and-a-half years.

SPRINT, naturally, stands for “SPeed and Runway INdependent Technologies.”

“Rock” Containing Stunning Agate Turns Out To Be 60-Million-Year-Old Dinosaur Egg

Posted by in category: futurism

Back in 1,883, a pretty agate mineral was registered to the Natural History Museum’s Mineralogy Collection. Around 15 centimeters (6 inches) across, almost completely spherical but otherwise unassuming, the specimen has remained in the collection for the last 175 years, until a chance finding revealed it to be a dinosaur egg.

The specimen’s pretty colors of light pink and white interior caught the eye of Robin Hansen, one of the Mineral Curators at the museum who helped prepare the specimen when it was selected to go on display in 2018. Then a trip to a mineral show in France helped reveal the significance of the rock.

‘While I was looking around the show, a dealer showed me an agatised dinosaur egg, which was spherical, had a thin rind, and dark agate in the middle,” recounts Hansen in a statement. “That was the lightbulb moment when I thought: ‘Hang on a minute, that looks a lot like the one we’ve just put on display in the Museum!’”

Oxygen-Ion Batteries Are Safe, Cheap To Produce, and Last Forever

Posted by in categories: energy, materials

Li-ion batteries power almost everything these days, but their star is waning as more promising chemistries are developed. Scientists at the Technische Universität Wien (TU Wien) in Austria have invented a new battery type that uses abundant materials. The Oxygen-ion battery is cheap to produce and can last forever.

Kickstarter Exoskeleton Claims It Gives Wearer Superhuman Abilities

Posted by in category: cyborgs

Another week, another exoskeleton on Kickstarter.

A Shanghai-based startup called Hypershell is trying its luck with an AI-powered exoskeleton that promises to take a big load off the next time you’re on a hike or run — and they say it’s even small enough to fit inside a backpack.

But the jury is still out on whether it’s anything more than a sci-fi-looking fashion accessory. To anyone thinking of backing, all the usual caveats about crowdfunding apply — it might not work at all, nevermind well, and it’s not uncommon to receive nothing at all.
