Emotion-detection applications built on outdated science, report warns  

Software that purportedly reads emotions in faces is being deployed or tested for a variety of purposes, including surveillance, hiring, clinical diagnosis, and market research. But a new scientific report finds that facial movements are an inexact gauge of a person's feelings, behaviors or intentions.

New low-cost thermoelectric material works at room temperature  

The widespread adoption of thermoelectric devices that can directly convert electricity into thermal energy for cooling and heating has been hindered, in part, by the lack of materials that are both inexpensive and highly efficient at room temperature. Now researchers have reported the discovery of a new material that works efficiently at room temperature while requiring almost no costly tellurium, a major component of the current state-of-the-art material.

MASCOT Confirms What Scientists Have Long Suspected  

Berlin, Germany (SPX) Jul 17, 2019 Ryugu and other asteroids of the common 'C-class' consist of more porous material than was previously thought. Small fragments of their material are therefore too fragile to survive entry into the atmosphere in the event of a collision with Earth. This has revealed the long-suspected cause of the deficit of this meteorite type in finds on Earth. Researchers at the German Aerospace Center (

Community size matters when people create a new language  

Why do some languages have simpler grammars than others? Researchers propose that the size of the community influences the complexity of the language that evolves in it. When small and large groups of participants played a 'communication game' using only gibberish words they had to invent, the languages invented by larger groups were more systematic than languages of smaller groups, showing that community size is important for shaping grammar.

This New Virtual Reality Glove Lets You Grab Digital Objects  

The VR glove in action.(Credit: Song et al, Scientific Reports, (2019) 9:8988) Our squishy human brains are notoriously easy to fool. Whether it's optical illusions or more advanced trickery, it doesn't take much to exploit our mind's weaknesses. But, that's also what enables virtual reality (VR) systems, where technology can effectively transport us to a digital world. And thanks to a newly developed VR glove, the effect might soon be better than ever. A team of engineer...

A graphene superconductor that plays more than one tune  

Researchers have developed a graphene device that's thinner than a human hair but has a depth of special traits. It easily switches from a superconducting material that conducts electricity without losing any energy, to an insulator that resists the flow of electric current, and back again to a superconductor -- all with a simple flip of a switch.

Sperm may offer the uterus a 'secret handshake'  

Why does it take 200 million sperm to fertilize a single egg? Part of the reason is bombardment by the female immune system, which very few sperm survive. Researchers have discovered a molecular handshake between sperm and uterine cells that may help sperm evade this attack -- or may help the immune system target the weakest sperm.

Pasadena CA (JPL) Jul 17, 2019 Raising crops on Mars is far easier in science fiction than it will be in real life: The Red Planet is an inhospitable world. Among other challenges, subzero temperatures mean water can persist on the surface only as ice, and the planet's atmosphere offers little protection to plants (or people) from the Sun's radiation. Of course, NASA has plans to eventually put humans on Mars, using les
