Most people take speech for granted, but it’s actually a complex process that involves both motions of the mouth and vibrations of folded tissues, called vocal cords, within the throat. If the vocal cords sustain injuries or other lesions, a person can lose the ability to speak. Now, researchers reporting in ACS Nano have developed a wearable artificial throat that, when attached to the neck like a temporary tattoo, can transform throat movements into sounds.

Scientists have developed detectors that measure movements on human skin, such as pulse or heartbeat. However, the devices typically can’t convert these motions into sounds. Recently, He Tian, Yi Yang, Tian-Ling Ren and colleagues developed a prototype artificial throat with both capabilities, but because the device needed to be taped to the skin, it wasn’t comfortable enough to wear for long periods of time. So the researchers wanted to develop a thinner, skin-like artificial throat that would adhere to the neck like a temporary tattoo.

To make their artificial throat, the researchers laser-scribed graphene on a thin sheet of polyvinyl alcohol film. The flexible device measured 0.6 by 1.2 inches, or about double the size of a person’s thumbnail. The researchers used water to attach the film to the skin over a volunteer’s throat and connected it with electrodes to a small armband that contained a circuit board, microcomputer, power amplifier and decoder. When the volunteer noiselessly imitated the throat motions of speech, the instrument converted these movements into emitted sounds, such as the words “OK” and “No.” The researchers say that, in the future, mute people could be trained to generate signals with their throats that the device would translate into speech.

TEPIC, Mexico (Thomson Reuters Foundation) — Tequila, avocado and corn are proving their worth beyond Mexican fiesta staples as key components for a fast-growing bioplastics market, with companies transforming waste from processing food crops into products such as bags, plates and even car parts.

Bioplastics make up less than 5 percent of the millions of tonnes of plastic produced each year around the world.

But as governments and consumers fret about the damage plastic is doing to the world’s oceans, scientists are experimenting by converting materials from cactus to shrimp shells and human waste into alternative greener plastics.

Technology that translates cortical activity into speech would be transformative for people unable to communicate as a result of neurological impairment. Decoding speech from neural activity is challenging because speaking requires extremely precise and dynamic control of multiple vocal tract articulators on the order of milliseconds. Here, we designed a neural decoder that explicitly leverages the continuous kinematic and sound representations encoded in cortical activity to generate fluent and intelligible speech. A recurrent neural network first decoded direct cortical recordings into vocal tract movement representations, and then transformed those representations to acoustic speech output. Modeling the articulatory dynamics of speech significantly enhanced performance with limited data. Naïve listeners were able to accurately identify and transcribe decoded sentences. Additionally, speech decoding was not only effective for audibly produced speech, but also when participants silently mimed speech. These results advance the development of speech neuroprosthetic technology to restore spoken communication in patients with disabling neurological disorders.

TARRYTOWN, N.Y., Aug. 12, 2019 /PRNewswire/ — Regeneron Pharmaceuticals, Inc. (NASDAQ: REGN) today announced that the Company was informed by study investigators that a randomized, controlled trial evaluating four investigational therapies for Ebola virus infection was stopped early because.

In a recent Security Response Center update from Microsoft, the company detailed the discovery of two “critical” Remote Code Execution (RCE) vulnerabilities.

The vulnerabilities are “wormable”, meaning that any future malware that exploits these could jump from computer to computer without any need for users sending it across.

Samsung will release a smartphone using new fast chargoing graphene battery technology that can fully charge in under 30 minutes according to gadgets leaker Evan Blass (@EVLeaks).

Samsung will release a smartphone powered by new graphene battery technology that can fully charge in under 30 minutes in 2020, or possibly 2021. This will be three to five times faster than today’s lithium-ion batteries which take about 90 minutes to charge.

In 2017, Samsung Advanced Institute of Technology (SAIT) announced they had developed a “graphene ball,” a unique battery material that enables a 45% increase in capacity, and five times faster-charging speeds than standard lithium-ion batteries. The breakthrough provides promise for the next generation secondary battery market, particularly related to mobile devices and electric vehicles. In its research, SAIT collaborated closely with Samsung SDI as well as a team from Seoul National University’s School of Chemical and Biological Engineering.

Robots are about to go underground — for a competition anyways.

The Defense Advanced Research Projects Agency (DARPA), the branch of the U.S. Department of Defense dedicated to developing new emerging technologies, is holding a challenge intended to develop technology for first responders and the military to map, navigate, and search underground. But the technology developed for the competition could also be used in future NASA missions to caves and lava tubes on other planets.

You open your browser to look at the Web. Do you know who is looking back at you?

Over a recent week of Web surfing, I peered under the hood of Google Chrome and found it brought along a few thousand friends. Shopping, news and even government sites quietly tagged my browser to let ad and data companies ride shotgun while I clicked around the Web.

This was made possible by the Web’s biggest snoop of all: Google. Seen from the inside, its Chrome browser looks a lot like surveillance software.
