The team developed a new liquid metal coating that can transform ordinary paper into self-adhesive gadgets capable of conducting heat and electricity. Although liquid metal is used in circuits and wearable sensors, the possibility of it being a coating has been unexplored until now.

Engineers from Rice University and the University of Maryland have created full-motion video technology that could potentially be used to make cameras that peer through fog, smoke, driving rain, murky water, skin, bone and other media that reflect scattered light and obscure objects from view.

“Imaging through scattering media is the ‘holy grail problem’ in optical imaging at this point,” said Rice’s Ashok Veeraraghavan, co-corresponding author of an open-access study published today in Science Advances. “Scattering is what makes light—which has lower wavelength, and therefore gives much better spatial resolution—unusable in many, many scenarios. If you can undo the effects of scattering, then imaging just goes so much further.”

WASHINGTON — Satellite manufacturer Terran Orbital has signed an agreement with French aerospace giant Safran to explore U.S.-based production of satellite propulsion systems, the companies announced June 23.

Under the agreement, Safran Electronics & Defense and Terran Orbital will investigate opportunities and prerequisites for the production of electric propulsion systems for satellites based on Safran’s PPSX00 plasma thruster.

The PPSX00 is a hall effect plasma thruster, recently introduced by Safran for the low Earth orbit satellite market.

The foremost physiological effect of psychedelics in the brain is to significantly reduce activity in multiple brain areas, which contradicts the mainstream reductionist expectation. Physicalist neuroscientists have proposed that an increase in brain noise explains the subjective richness of a psychedelic experience, but a psychedelic experience isn’t akin to TV static, argues Bernardo Kastrup.

Before 2012, the generally accepted wisdom in neuroscience was that psychedelic substances—which lead to unfathomably rich experiential states—stimulate neuronal activity and light up the brain like a Christmas tree. Modern neuroimaging, however, now shows that they do precisely the opposite: the foremost physiological effect of psychedelics in the brain is to significantly reduce activity in multiple brain areas, while increasing it nowhere in the brain beyond measurement error. This has been consistently demonstrated for multiple psychedelic substances (psilocybin, LSD, DMT), with the use of multiple neuroimaging technologies (EEG, MEG, fMRI), and by a variety of different research groups (in Switzerland, Brazil, the United Kingdom, etc.). Neuroscientist Prof. Edward F. Kelly and I published an essay on Scientific American providing an overview of, and references to, many of these studies.

These results contradict the mainstream metaphysics of physicalism for obvious reasons: experience is supposed to be generated by metabolic neuronal activity. A dead person with no metabolism experiences nothing because their brain has no activity. A living person does because their brain does have metabolic activity—or so the story goes. And since neuronal activity supposedly causes experiences, there can be nothing to experience but what can be traced back to patterns of neuronal activity (otherwise, one would have to speak of disembodied experience). Ergo, richer, more intense experience—such as the psychedelic state—should be accompanied by increased activity somewhere in the brain; for it is this increase that supposedly causes the increased richness and intensity of the experience.

People who owned black-and-white television sets until the 1980s didn’t know what they were missing until they got a color TV. A similar switch could happen in the world of genomics as researchers at the Berlin Institute of Medical Systems Biology of the Max Delbrück Center (MDC-BIMSB) have developed a technique called Genome Architecture Mapping (“GAM”) to peer into the genome and see it in glorious technicolor. GAM reveals information about the genome’s spatial architecture that is invisible to scientists using solely Hi-C, a workhorse tool developed in 2009 to study DNA interactions, reports a new study in Nature Methods by the Pombo lab.

With a black-and-white TV, you can see the shapes but everything looks grey. But if you have a color TV and look at flowers, you realize that they are red, yellow and white and we were unaware of it. Similarly, there’s also information in the way the genome is folded in three-dimensions that we have not been aware of.

ALBUQUERQUE, N.M. — In people with epilepsy, seizure-alert dogs can smell small changes in body chemistry and warn of an impending seizure an hour or more before it occurs. Inspired by this feat of nature, a team of researchers has sniffed out a way to replicate the ability with technology.

According to a recent tweet from Twitter owner Elon Musk who recently confirmed the app, Twitter is preparing to launch its own video app for Smart TVs.
