Could your computer please be more polite? Thank you

In a tense time when a pandemic rages, politicians wrangle for votes and protesters demand racial justice, a little politeness and courtesy go a long way. Now researchers at Carnegie Mellon University have developed an automated method for making communications more polite. Specifically, the method takes nonpolite directives or requests -- those that use either impolite or neutral language -- and restructures them or adds words to make them more well-mannered.

CMU demonstrates nanoscale technology that causes plants to absorb nutrients with nearly 100% efficiency

Spraying plants with fertilizers and pesticides is typically a highly lossy affair – as little as 1% of the substances currently used in industrial and food production farming is actually taken up by the plant, while the rest leaches off into the soil. A new technology demonstrated for the first time by Carnegie Mellon University’s Greg Lowry and his team reverses that – cause a plant to absorb molecules with up to 99 percent efficiency, meaning only 1 percent is wasted. There are efficiency ...

Smartphone videos produce highly realistic 3D face reconstructions

Normally, it takes pricey equipment and expertise to create an accurate 3D reconstruction of someone's face. Now, Carnegie Mellon University researchers have pulled off the feat using video recorded on an ordinary smartphone. Shooting a continuous video of the front and sides of the face generates a dense cloud of data. A two-step process developed by CMU's Robotics Institute uses that data, with some help from deep learning algorithms, to build a digital reconstruction of the face.

A neuroscientist's take on synthetic telepathy, electrified ESP, and mind control

Telepathy. ESP. The ability to communicate thoughts, feelings, or experiences without using our known sensory channels is a timeless superpower. Soon, advances in neuroscience, molecular biology, and computer science will make some kinds of synthetic telepathy possible. Meanwhile though, methods to treat brain disorders through magnetic stimulation of brain circuits could enable crude (or eventually not-so-crude) mind control. National Institutes of Health neuroscientist R. Douglas Fields -- a...
