The importance of the Earth's atmosphere in creating the large storms that affect satellite communications      (via sciencedaily.com)     Original source 

Large geomagnetic storms disrupt radio signals and GPS. Now, researchers have identified the previous underestimated role of the ionosphere, a region of Earth's upper atmosphere that contains a high concentration of ions and free electrons, in determining how such storms develop. Understanding the interactions that cause large geomagnetic storms is important because they can disrupt radio signals and GPS. Their findings may help predict storms with the greatest potential consequences.

DNA Origami nanoturbine sets new horizon for nanomotors      (via sciencedaily.com)     Original source 

Researchers introduce a pioneering breakthrough in the world of nanomotors -- the DNA origami nanoturbine. This nanoscale device could represent a paradigm shift, harnessing power from ion gradients or electrical potential across a solid-state nanopore to drive the turbine into mechanical rotations. The core of this pioneering discovery is the design, construction, and driven motion of a 'DNA origami' turbine, which features three chiral blades, all within a minuscule 25-nanometer frame, operating in a solid-state nanopore. By ingeniously designing two chiral turbines, researchers now have the capability to dictate the direction of rotation, clockwise or anticlockwise.

Scientists discover deepest known evidence of coral reef bleaching      (via sciencedaily.com)     Original source 

Scientists have discovered the deepest known evidence of coral reef bleaching, more than 90 metres below the surface of the Indian Ocean. Identified during a research cruise, the damage to the deeper reefs in the Central Indian Ocean has been attributed to significant changes in the region's ocean temperature caused by the Indian Ocean Dipole. The researchers have also warned such incidences are only likely to increase as a result of present and future climate change.
