A Magnetic Twist to Graphene Could Offer a Dramatic Increase in Processing Speeds Compared to Electronics
Posted by Genevieve Klien in categories: particle physics, quantum physics
Electrons in materials have a property known as ‘spin’, which is responsible for a variety of properties, the most well-known of which is magnetism. Permanent magnets, like the ones used for refrigerator doors, have all the spins in their electrons aligned in the same direction. Scientists refer to this behavior as ferromagnetism, and the research field of trying to manipulate spin as spintronics.
Down in the quantum world, spins can arrange in more exotic ways, giving rise to frustrated states and entangled magnets. Interestingly, a property similar to spin, known as “the valley,” appears in graphene materials. This unique feature has given rise to the field of valleytronics, which aims to exploit the valley property for emergent physics and information processing, very much like spintronics relies on pure spin physics.

Grumman’s LongShot drone can search & destroy
Posted by Raphael Ramos in categories: drones, military, robotics/AI
Instead of firing missiles, planes may carry and launch unmanned drones that will be able to shoot their own missiles to search and destroy targets.
Aerospace giant Northrop Grumman is wasting no time in this competition.
Just two days after DARPA named it as one of three competitors for the LongShot contract, the company released an image of its concept for an air-launched unmanned aircraft system (UAS), Aviation Week reported.

Cruelty-Free Wallets From Banana Tree Waste
Posted by Raphael Ramos in category: sustainability
So you like a leather wallet? Check out this sustainable alternative made from banana tree waste! After banana trees are harvested, they’re chopped down to make way for younger fruiting trees, and their waste can become SO MUCH STUFF! Cruelty-free and super cool, what’s not to love?
Neil Tyson is a man to listen to!!
Astrophysicist that I have learned much from.

How Solar Sails Are Remaking Space Exploration
Posted by Derick Lee in categories: business, robotics/AI, space
Using the pressure of the sun’s rays to propel spacecraft, solar sails will allow future unmanned missions to be longer and cheaper while reaching the outer solar system—and possibly beyond.
