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…
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,…
Study in twins finds our sensitivity is partly in our genes
Some people are more sensitive than others — and around half of these differences can be attributed to our genes, new research has found. Source: https://www.sciencedaily.com/releases/2020/06/200603104552.htm
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…
