Hackers Could Use IoT Botnets To Manipulate Energy Markets

An anonymous reader quotes a report from Wired: At the Black Hat security conference on Wednesday, [researchers at the Georgia Institute of Technology] will present their findings, which suggest that high-wattage IoT botnets — made up of power-guzzling devices like air conditioners, car chargers, and smart thermostats — could be deployed strategically to increase demand at certain times in any of…

Major Study Rules Out Super-High and Low Climate Sensitivity To CO2

Scott K. Johnson writes via Ars Technica: One of the most important numbers in climate science is 3C. This isn’t about a projection of future warming or the impacts that come with it, though. It’s about how much warming you get if you double the amount of greenhouse gasses in the atmosphere. That value can be made more general as a…

Hoax That Fooled Armed Protesters Was Created By a Socialist Troll on Food Stamps

Remember that anonymous online hoaxster who urged hundreds of armed protesters to counter a non-existent flag-burning event at America’s historic Civil War battefield at Gettysburg? An investigation by the Washington Post reveals that the hoaxster had in fact been a “lifelong Democrat” before instead registering in 2015 with the Socialist Party — and that he now collects food stamps:
Adam Rahuba, a…

Declining Eyesight Can Be Improved By Looking At Red Light, Pilot Study Says

swell shares the findings from a small pilot study that suggests a few minutes of looking into a deep red light could have a dramatic effect on preventing eyesight decline as we age. CNN reports: Researchers recruited 12 men and 12 women, whose ages ranged from 28 to 72. Each participant was given a small handheld flashlight that emitted a red…

New quantum sensing technique allows high-resolution nuclear magnetic resonance spectroscopy

Nuclear magnetic resonance (NMR) spectroscopy is a widely used tool for chemical analysis and molecular structure recognition. Because it typically relies on the weak magnetic fields produced by a small thermal nuclear spin polarization, NMR suffers from poor sensitivity compared to other analytical techniques. A conventional NMR apparatus typically uses large sample volumes of about a milliliter—large enough to contain around…

Supergiant atmosphere of Antares revealed by radio telescopes

An international team of astronomers has created the most detailed map yet of the atmosphere of the red supergiant star Antares. The unprecedented sensitivity and resolution of both the Atacama Large Millimeter/submillimeter Array (ALMA) and the National Science Foundation’s Karl G. Jansky Very Large Array (VLA) revealed the size and temperature of Antares’ atmosphere from just above the star’s surface, throughout…

A new catalog of infrared dark clouds

Infrared dark clouds (IRDCs) are dark patches of cold dust and gas seen in the sky against the bright diffuse infrared glow of warm dust in our galaxy. These IRDCs, massive and rich in molecules, are natural sites for star birth—one of the main reasons why astronomers are actively studying them. IRDCs were first detected by two early space infrared missions,…

Will you see Comet SWAN?

Another comet – Comet SWAN – is creating a buzz. There’ve been some amazing long-exposure photos of it. Will you be able to see it? Maybe, but conditions are challenging. Charts and more here. Source: https://earthsky.org/space/comet-c-2020-f8-swan-how-to-see-charts…
