"Think of a sailboat in space. If you've one and you're trying to sail into the wind, you've to tack back and forth. But with a diffractive sail, you would be able to sail directly into the wind, getting the most efficient thrust. And be able to explore the Sun like never before," Amber Dubill of the Johns Hopkins University Applied Physics Laboratory in Laurel, Maryland, tells IE about her project.
Researchers at the University of Helsinki have demonstrated that brains synchronize while playing online games even when the participants are not physically present in the same room.
