New Electronic Device Developed to Help Mute People Talk

New Electronic Device Developed to Help Mute People Talk

Two Chinese researchers have created a prototype device that can be taped to the skin to measure the motions and vibrations of the vocal cords and transform them into sounds.

The researchers also improved the device so it becomes thinner and lighter, so when attached to the neck like a temporary tattoo, it doesn't cause the wearer any discomfort, the German News Agency reported.

According to the ACS Nano journal, speech is 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.

Researchers He Tian, Yi Yang, Tian-Ling Ren and colleagues used 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.

The Science Daily website reported that the instrument converts the throat's 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.

Researchers have long said that the human brain is not set up to multitask — but new research is challenging that understanding.

Experts previously explained that when we believe we’re multitasking, we’re actually just quickly switching between tasks. That’s because the area of the brain that manages thinking, the prefrontal cortex, can only really handle one thing at a time, according to The Independent.

But another region of the brain involved in memory lends a helping hand over time, new research has shown. When people needed to perform image sorting tests over the course of weeks, the tests initially activated the prefrontal cortex and later activated the temporal cortex.

Over time, the brain is remodeled, Maximilian Riesenhuber, a professor of neuroscience at Georgetown University School of Medicine, explained in a statement. The prefrontal cortex passes responsibility to the temporal cortex and is free for “whatever else you want to do, increasing your capacity.”

“What we show is that the circuitry actually changes so the brain can do two things at once,” he said. “This really is true multitasking.”

The researchers wanted to understand why people need to focus when learning a task for the first time and can also do other things simultaneously when they become experienced. For example, long-time drivers are able to listen to music and engage in conversations.

Men and women in the small study were trained to sort morphed images of cars into two categories using an image-sorting app, completing more than 30,000 trials over the course of 5-10 weeks.

The researchers scanned their brains before and after they completed the trials, revealing the change.

“Previous studies have shown that parts of the temporal cortex can be activated by particular object categories in experienced observers – birds, cars, even Pokémon – but a limitation of all of those studies is that they only looked after people became experts,” Patrick Cox, an assistant professor of psychology at Lehigh University, said.

He added: “The strength of this study is that it is longitudinal: We measure before and after training, so we can see that extensive training essentially put a category-selective area in the temporal lobe that was not there before.”

It’s unclear why right now. However, multitasking has been linked to experiencing stress and other mental health impacts, Brown University Health points out. That’s part of why experts say it could actually hinder productivity.

“This is unlocking a whole new set of questions,” he said. “What is the source of that variability? We don’t know yet.”

Swimmers will for the second year be able to cool off at designated points along the Seine River in Paris this summer, authorities said Friday, as well as along the Marne River in the suburbs.

In Paris, the swimming season was to open at three official bathing sites on July 4, the mayor's office said.

The Seine reopened to swimmers last summer for the first time in a century, after Paris poured more than a billion euros ($1.15 billion) into a years-long effort to making the waters clean enough to use in the 2024 Olympics.

Sites this year will again include the Bras de Grenelle near the Eiffel Tower, the Bras Marie -- a short walk from Notre-Dame -- and Bercy, on the eastern side.

Some 100,000 people last year queued to jump in, the city said, despite a slow start to the season with rain disrupting the water quality.

Some 50,000 swimmers jumped into the Marne River in the eastern suburbs last year.

The bathing spots in Joinville-le-Pont, Champigny-sur-Marne, Saint-Maur-des-Fosses and Maison-Alfort would again welcome swimmers. A fifth spot would be added this year at Neuilly-sur-Marne northeast of Paris.

French authorities warned against swimming in parts of the rivers without lifeguards.

Independent Researcher Exposes Basic Blunder in Scores of Cancer Studies

An independent researcher has uncovered potential blunder in scores of scientific studies, including cancer-related research, as a result of inappropriate antibody use in laboratory experiments, raising questions about the reliability of some of the results published in prestigious scientific journals.

The researcher found that scientists at Cambridge, Oxford, Stanford and other universities appear to have accidentally used the wrong ingredient in their experiments, muddling two proteins with similar names but entirely different sequences and functions.

Several British media outlets said researcher Sholto David reviewed the full text of 334 research papers to determine whether the antibody used in the studies was correctly intended for p16-ARC or incorrectly used to try and bind p16-INK4a.

P16-INK4a acts as a tumor suppressor by halting the cell cycle and is widely studied in cancer biology and is considered a key biomarker of ageing.

He found astonishing result: 95% of these papers have got it wrong.

“The vast majority of researchers who purchased antibodies have tried to use them to investigate p16-INK4a expression. Only 17 used these p16-ARC antibodies correctly,” he said in his research.

David said the implications are not good, to put it mildly.

“And these are not just insignificant papers. There are papers with hundreds of citations in high impact journals claiming to probe for p16-INK4a with antibodies which do not bind p16-INK4a,” he noted.
