Optogenetics is a very promising technique – among other things, it may one day be used to reduce anxiety, treat addiction, and even reverse blindness. A newly developed device could soon also make it considerably less invasive, and thus more doable. Source of Article
Leveraging salt could help us avoid much of the cost and difficulty in sourcing scarcer lithium, and Chinese giant CATL is looking to lead the charge by launching its first commercial sodium-ion battery. Source of Article
A new mathematical study suggests that the abandoned Ascent Stage of the Apollo 11 mission's Eagle Lunar Module, long believed to have crashed on the Moon in 1969, may be circling our largest natural satellite in a stable orbit. Source of Article
Scientists have stumbled across a mechanism by which the immune system triggers the secretion of fat cells through the skin. The mechanism may translate from mice into humans, but turning it into a safe obesity therapy could be challenging. Source of Article
Although optical fibers are highly effective at data transmission, they're also relatively brittle. An experimental new type of optical fiber addresses that limitation, by incorporating a core made of liquid glycerol. Source of Article
Following the official launch of "the world's most powerful tidal turbine" in April, Orbital Marine Power has announced that the O2 has started grid-connected power generation at the European Marine Energy Centre in Orkney. Source of Article
About 66 million years ago, a gigantic object crashed into the Earth, triggering a mass extinction that took out the dinosaurs. Now, scientists say they’ve traced the culprit back to its point of origin, identifying it as a “dark primitive asteroid.” Source of Article
We're seeing some significant advances in efforts to leverage light-sensitive proteins to improve human health, a field known as optogenetics, but new research out of Germany flips the script on this emerging technology. Source of Article
Boston's Form Energy says its iron-air batteries store up to 100 hours' worth of energy at a tenth the cost of a lithium battery farm. They could make a huge contribution to long-term storage as the world makes its transition toward renewable energy. Source of Article
Microglia are immune cells that clean out unwanted debris in the brain and central nervous system, but it turns out they might help heal injured neurons too – a discovery that could pave the way for new treatments for epilepsy and other conditions. Source of Article
