The Whitest Paint Is Here & It’s the Coolest – Could Help Curb Global Warming

"Using high-accuracy temperature reading equipment called thermocouples, the researchers demonstrated outdoors that the paint can keep surfaces 19 degrees Fahrenheit cooler than their ambient surroundings at night. It can also cool surfaces 8 degrees Fahrenheit below their surroundings under strong sunlight during noon hours.

The paint’s solar reflectance is so effective, it even worked in the middle of winter. During an outdoor test with an ambient temperature of 43 degrees Fahrenheit, the paint still managed to lower the sample temperature by 18 degrees Fahrenheit."

"Cool" concept...but does that last sentence actually mean the temperature dropped well below freezing?

New Type of Battery Created That Can Charge 10x Faster Than Lithium-Ion Batteries

"A battery manufactured using our polymer will charge in seconds – about ten times faster than a traditional lithium-ion battery. This has already been demonstrated through a series of experiments. However, at this stage, it is still lagging behind in terms of capacity – 30 to 40% lower than in lithium-ion batteries."

Genetic Engineering 2.0: An On-Off Switch for Gene Editing

“The big story here is we now have a simple tool that can silence the vast majority of genes,” says Weissman, who is also a professor of biology at MIT and an investigator with the Howard Hughes Medical Institute. “We can do this for multiple genes at the same time without any DNA damage, with great deal of homogeneity, and in a way that can be reversed. It’s a great tool for controlling gene expression.”
