(Em)powering world peace and prosperity using astroelectricity

Posted by in categories: engineering, nuclear energy, solar power, space, sustainability

Mike Snead, P.E., president of the Spacefaring Institute, was invited to present at the Envision Humanity conference held in Portugal on 18 July 2020. This presentation was delivered via video. It addresses the world green energy needed to “globally reset” human civilization using astroelectricity (GEO space-based solar power) to achieve sustainable, prosperous living worldwide. The presentation also shows why the “Green New Deal’s” call to use terrestrial nuclear and renewable energy to replace fossil carbon fuels is not a practical solution. The presentation provides an interesting way to understand the magnitude of the engineering challenge and options available to complete this important transition to sustainable energy.

Ridley Scott is back to making operatic sci-fi in new Raised by Wolves trailer

Posted by in category: alien life

https://youtube.com/watch?v=VnwttF7uv1I

The first two episodes will be directed by Ridley Scott, who has a history of producing grandiose, high-concept, philosophical sci-fi (see: Prometheus and Alien Covenant) as well as treatises on religious tribalism (like in Kingdom of Heaven).


The visual spectacle aims to be a think piece on the role of faith in civilization.

Please remain calm while the robot swabs your nose

Posted by in categories: biotech/medical, robotics/AI

Taiwanese medtech firm Brain Navi has created a robot that autonomously swabs your nose as part of a test for COVID-19. The startup says the robot could make mass-testing faster and more reliable, but doctors say the machine might just be too scary for patients to bear.

Posted by in categories: robotics/AI, security

This piece was written as part of the Artificial Intelligence and International Stability Project at the Center for a New American Security, an independent, nonprofit organization based in Washington, D.C. Funded by Carnegie Corporation of New York, the project promotes thinking and analysis on AI and international stability. Given the likely importance that advances in artificial intelligence could play in shaping our future, it is critical to begin a discussion about ways to take advantage of the benefits of AI and autonomous systems, while mitigating the risks. The views expressed here are solely those of the author and do not represent positions of IEEE Spectrum or the IEEE.

New Bluetooth Vulnerability: Hackers Could Spy on You

Posted by in categories: cybercrime/malcode, encryption, mobile phones

O,.o.


Millions of us use Bluetooth wireless communications every day—to make phone calls when driving, with our fitness trackers, streaming at work or play. Innocent enough, seemingly. But no technology comes without a warning: a recently discovered Bluetooth vulnerability allows hackers to spy on your conversations or take control of your smart phone. The vulnerability deals with the encryption between two devices. It even has a name—a KNOB hack (Key Negotiation Of Bluetooth).

This is not the first time Bluetooth has been hacked and it likely won’t be the last. And this one has its limitations. To take advantage of the KNOB vulnerability the hacker has to be in close proximity of your phone. There is also currently no evidence that this vulnerability has been exploited maliciously.

Genetic Variants May Explain High Levels of Antibodies Against Epstein-Barr Virus in MS, Study Suggests

Posted by in categories: biotech/medical, genetics, neuroscience

Genetic variants may contribute to increased levels of antibodies against proteins of the Epstein-Barr virus — a known environmental risk factor for multiple sclerosis (MS) — in MS patients and their siblings, a study suggests.

The study, “EBNA-1 titer gradient in families with multiple sclerosis indicates a genetic contribution,” was published in the journal Neurology, Neuroimmunology and Neuroinflammation.

Martian Soil May Not Support Astronaut Agriculture

Posted by in categories: chemistry, food, space

In The Martian, Matt Damon’s character is able to survive being marooned on Mars by growing potatoes in the Martian soil. While fictional, this plot point reflects a real need for in-situ resource utilization (ISRU) to support long-term human space exploration missions. A new study by a team from the Florida Institute of Technology suggests that the Martian soil may be more hostile to plant life than previously thought and that the capability of growing Martian potatoes will require additional development to make agriculture feasible.

The researchers studied three examples of Martian regolith simulants. These simulants are produced from materials found on Earth to reproduce the mineralogy and chemistry of the soil we expect to find on Mars. They found that none of these simulants were able to support plant life on their own, partly due to nitrogen deficiency, and only two were able to do so when nutrient supplements were added. More crucially, none of these simulants could support plant life at all when calcium perchlorate — a common, and toxic, substance on Mars’s surface — was added. Their results suggest that any scheme for ISRU agriculture on the surface of Mars must plan to remediate, or otherwise avoid, the toxic effects of perchlorate before attempting an extraterrestrial harvest.
