Man gets mind-controlled robotic arm powered by Bluetooth
short by Gaurav Shroff / on 26 Apr 2017,Wednesday
A Dutch patient recently received a 'click-on prosthetic arm' that can be controlled with his thoughts. The arm is directly connected to the bone while the "mind control" is enabled by connecting patient's nerves to the arm, with a Bluetooth bracelet to receive signals. The click-on device doesn't need a prosthesis socket and can be removed easily, doctors said.

India's coal plants may hinder Paris climate goals: US study
short by Gaurav Shroff / on 27 Apr 2017,Thursday
India's plan to build nearly 370 coal-fired power plants may "single-handedly jeopardise" the planet's effort to achieve Paris Agreement's goals of limiting global warming, US researchers have warned. Coal power plants contributed to 41% of global carbon dioxide emissions in 2015, researchers said, adding that if India produced 40% power from non-fossil sources, electricity demands would be met.

Discovery credits of Ring Nebula corrected after 238 years
short by Gaurav Shroff / on 26 Apr 2017,Wednesday
Historians credit French astronomer Antoine Darquier for the discovery of the Ring Nebula in 1779. However, US-based scientists found his compatriot Charles Messier found the Nebula a week before, calling it M57. On comparing their notes, scientists found that Messier credited Darquier as the first person to "spot" the Nebula after the former's discovery, which had confused the historians.
