Offshore wind farms are vulnerable to cyberattacks      (via sciencedaily.com)     Original source 

Researchers have presented a new study on cyberattack risks to offshore wind farms in Glasgow, United Kingdom. They looked specifically at wind farms that use voltage-source-converter high-voltage direct-current (VSC-HVDC) connections, which are rapidly becoming the most cost-effective solution to harvest offshore wind energy around the world. They found that their complex, hybrid-communication architecture presents multiple access points for cyberattacks.

New study unveils how plants control the production of reactive oxygen species      (via sciencedaily.com)     Original source 

Reactive oxygen species (ROS), though generally regarded as toxic byproducts of biological processes, serve many important functions in plants. However, the precise mechanism that plants use to regulate the production of ROS remains elusive. In a recent study, researchers clarified how an important ROS-generating enzyme is activated, revealing mechanisms likely conserved across all land plants. Their findings could pave the way for breakthroughs in agricultural and environmental remediation tools.

Discovering the physics behind 300-year-old firefighting methods      (via sciencedaily.com)     Original source 

Inspired by a 1725 fire engine that pumped water at larger distances and higher speeds than previously possible, authors analyzed the pressure chamber's Windkessel effect to capture the physics behind this widely used, enduring technology. They compared the initial state of the chamber, the rate at which bucket brigades could pour water in (volumetric inflow), the length of time pressure builds, and the effects on output flow rate. Next, the authors plan to examine the physiological Windkessel involved in the heart-aorta system.
