Neuroimaging Of Brain Shows Who Spoke To A Person And What Was Said
Posted by Richard Christophr Saragoza in categories: computing, information science, neuroscience
Flashback to 2 years ago…
Scientists from Maastricht University have developed a method to look into the brain of a person and read out who has spoken to him or her and what was said. With the help of neuroimaging and data mining techniques the researchers mapped the brain activity associated with the recognition of speech sounds and voices.
In their Science article “‘Who’ is Saying ‘What’? Brain-Based Decoding of Human Voice and Speech,” the four authors demonstrate that speech sounds and voices can be identified by means of a unique ‘neural fingerprint’ in the listener’s brain. In the future this new knowledge could be used to improve computer systems for automatic speech and speaker recognition.
Seven study subjects listened to three different speech sounds (the vowels /a/, /i/ and /u/), spoken by three different people, while their brain activity was mapped using neuroimaging techniques (fMRI). With the help of data mining methods the researchers developed an algorithm to translate this brain activity into unique patterns that determine the identity of a speech sound or a voice. The various acoustic characteristics of vocal cord vibrations (neural patterns) were found to determine the brain activity.

Is Life Extension Natural? | LifeXtenShow
Posted by Paul Battista in category: life extension
Aging is just natural, while rejuvenation therapies aren’t, but does this mean we should accept aging as it is and forget about rejuvenation? Not at all, and as Nicola explains in this video, just because something is natural, it’s not also automatically good for you.

Latest claim of turning hydrogen into a metal may be the most solid yet
Posted by Quinn Sena in category: materials
If true, the study would complete a decades-long quest to find the elusive material. But such claims have been made prematurely many times before.

At 100 years old, the world’s oldest billionaire still goes to the office every day
Posted by Franco Cortese in category: life extension
At 100 years old, the world’s oldest billionaire would be forgiven for taking it easy and enjoying the riches of his eight-decade career.
But for Chang Yun Chung, founder of Pacific International Lines (PIL), staying at home isn’t an option. Despite handing over the role of executive chairman to his son, Teo Siong Seng, earlier this year, the centenarian Singaporean insists on going into the office every day.
“It’s my habit,” Chang told CNBC in a recent episode of “Managing Asia.”

Wasp Colony Given Colored Construction Paper Builds an Amazing Rainbow Nest
Posted by Quinn Sena in categories: biological, drones, habitats
Biology student Mattia Menchetti performed an experiment on a colony of European paper wasps which yielded some very colorful results. Paper wasps are known for their water-resistant nests constructed out of fibers of dead wood and plant stems which have been chewed into a pulp and mixed with saliva. Menchetti provided a captive colony of these wasps with colored paper and in a beautiful display of entomological artwork, the insects produced a vibrant, rainbow nest.
Menchetti began by giving the wasps bits of yellow paper, and slowly introduced more and more multicolored sheets. The colony happily made use of the material to construct a sturdy, technicolor home to house their larvae. Paper wasps are some of the most common wasp species, typically seen in backyards around North America. They tend to establish a single nest across multiple seasons and generations; for this reason, their homes must be incredibly durable. A protein found in the saliva of these wasps is actually so effective at waterproofing their nests that it has been used by scientists to construct a biodegradable drone.
Menchetti has performed a variety of scientific studies about insects, mammals, and the ecology of alien species, which he explains in further detail on his website.

Discovered: Lord Byron’s Copy of Frankenstein Signed by Mary Shelley
Posted by Quinn Sena in category: neuroscience
The story behind the writing of Frankenstein is famous. In 1816, Mary Shelley and Percy Bysshe Shelley, summering near Lake Geneva in Switzerland, were challenged by Lord Byron to take part in a competition to write a frightening tale. Mary, only 18 years old, later had a waking dream of sorts where she imagined the premise of her book:
When I placed my head on my pillow, I did not sleep, nor could I be said to think. My imagination, unbidden, possessed and guided me, gifting the successive images that arose in my mind with a vividness far beyond the usual bounds of reverie. I saw — with shut eyes, but acute mental vision, — I saw the pale student of unhallowed arts kneeling beside the thing he had put together. I saw the hideous phantasm of a man stretched out, and then, on the working of some powerful engine, show signs of life, and stir with an uneasy, half vital motion.
This became the kernel of Frankenstein; or, The Modern Prometheus, the novel first published in London in 1818, with only 500 copies put in circulation.

Diamond on silicon chips are running at 100 Gigahertz and can also make power chips for directing 10,000 volts
Posted by Quinn Sena in categories: computing, mobile phones
Circa 2016
Diamond computer chips running at 100-GHz have been demonstrated by Akhan Semiconductor. They are currently using design rules in the 100s of nanometers.
Developers are focusing on power applications on 12-inch wafers. They hope to drive down the costs of production with higher volumes. Power devices are moving into pilot production at a fab. They are using the fab-lite model—that is produce small- to medium-sized runs themselves. They will then transfer their process to foundries when they ramp up into volume production.
