Why did “A Brief History of Time” make its author the most famous scientist in the world?

For 50 years, AeroVironment has advanced UAV development. Today, the company is a Technology Solutions Provider at the intersection of four future-defining technologies: robotics, sensors, analytics and connectivity. Its culture of experimentation and R&D dates back to its founder, Dr. Paul MacCready Jr., whose achievements earned him the nickname “the father of human-powered flight”. From deploying the world’s most popular sUAS to designing the helicopter that’s en route to fly in Mars’ thin atmosphere, AeroVironment’s collective accomplishments provide a case study of imagination, innovation and collaboration — one that has and will bring effective solutions to frontlines, farms and frontiers, yesterday, today and tomorrow.

Leading the Way: UAS Capabilities – Onward and Upward

From solar-powered aircraft to the first hand-launched small UAS (sUAS) for military reconnaissance, AeroVironment literally launched the era of small aerial vehicles for environmental, commercial and defense purposes. For 35 years, the company has made its UAVs smaller and simpler, yet with multiple and ever-more-innovative functionality.

Days after the first malware targeting Apple M1 chips was discovered in the wild, researchers have disclosed yet another previously undetected piece of malicious software that was found in about 30000 Macs running Intel x86_64 and the iPhone maker’s M1 processors.

However, the ultimate goal of the operation remains something of a conundrum, what with the lack of a next-stage or final payload leaving researchers unsure of its distribution timeline and whether the threat is just under active development.

Calling the malware “Silver Sparrow,” cybersecurity firm Red Canary said it identified two different versions of the malware — one compiled only for Intel x86_64 and uploaded to VirusTotal on August 31, 2020 (version 1), and a second variant submitted to the database on January 22 that’s compatible with both Intel x86_64 and M1 ARM64 architectures (version 2).

Developers for Apple’s platforms are being hacked through importing shared Xcode projects infected with malware.

Researchers from SentinelOne detailed the growing trend after discovering a macOS malware dubbed XcodeSpy.

“Threat actors are abusing the Run Script feature in Apple’s Xcode IDE to infect unsuspecting Apple Developers via shared Xcode Projects,” the researchers explained.

Would aliens be friendly or a threat? — Part I of a new series.

Any advanced alien species would have a social structure, but would also likely have predatory roots.

Scientists from MIT and the Indian Institute of Technology Madras have grown small amounts of self-organizing brain tissue, known as organoids, in a tiny 3D-printed system that allows observation while they grow and develop. The work is reported in Biomicrofluidics.

Current technology for real-time observation of growing organoids involves the use of commercial culture dishes with many wells in a glass-bottomed plate placed under a microscope. The plates are costly and only compatible with specific microscopes. They do not allow for the flow or replenishment of a nutrient medium to the growing tissue.

Recent advances have used a technique known as microfluidics, where a nutrient medium is delivered through small tubes connected to a tiny platform or chip. These microfluidic devices are, however, expensive and challenging to manufacture.

PARIS: Scientists believe they may have discovered a “brand-new force of nature” at CERN’s Large Hadron Collider that could explain why certain atomic particles behave unexpectedly and which may transform our understanding the rudiments of physics.

Authors of the research said this week that their results should “get physicists’ hearts beating just a little faster” after they discovered evidence of a “brand-new” type of particle.

Since its inception over a decade ago, the Large Hadron Collider (LHC) has sought to delve into the secrets of the universe by studying the smallest discreet particles of matter as they collide at nearly the speed of light.

“Before we began this study, we had extensive data showing that spaceflight completely reprogrammed Salmonella at every level to become a better pathogen,”

Astronauts face many challenges to their health, due to the exceptional conditions of spaceflight. Among these are a variety of infectious microbes that can attack their suppressed immune systems.

Now, in the first study of its kind, Cheryl Nickerson, lead author Jennifer Barrila, and their colleagues describe the infection of human cells by the intestinal pathogen Salmonella Typhimurium during spaceflight. They show how the microgravity environment of spaceflight changes the molecular profile of human intestinal cells and how these expression patterns are further changed in response to infection. In another first, the researchers were also able to detect molecular changes in the bacterial pathogen while inside the infected host cells.
