Scientists develop AI that can turn brain activity into text

Posted by in categories: cyborgs, neuroscience, robotics/AI

“We are not there yet but we think this could be the basis of a speech prosthesis,” said Dr Joseph Makin, co-author of the research from the University of California, San Francisco.

Writing in the journal Nature Neuroscience, Makin and colleagues reveal how they developed their system by recruiting four participants who had electrode arrays implanted in their brain to monitor epileptic seizures.

These participants were asked to read aloud from 50 set sentences multiple times, including “Tina Turner is a pop singer”, and “Those thieves stole 30 jewels”. The team tracked their neural activity while they were speaking.

Astronomers Observe Blasting Supermassive Black Hole Jets From The Early Universe

Posted by in category: cosmology

O,.,o.


In the far reaches of the Universe, astronomers have managed to capture a rare interaction. As a supermassive black hole ravenously slurps down matter around it, it’s sending out jets of plasma — pushing into and heating the gas in the galaxy around it.

This is difficult to capture at the best of times, but this case was a particularly impressive feat. The galaxy in question is a whopping 11 billion light-years away — when the Universe was less than 3 billion years old.

NASA’s new spacesuit can withstand over 120°C, removes toxic gases and regulates temperature

Posted by in category: space

NASA’s new spacesuit may not look any different from the one used for spacewalks outside the International Space Station recently, but the US space agency says the suit is designed to achieve more complex tasks than its predecessors. The new suit, which will be worn by astronauts on the Artemis lunar exploration program, is called the Exploration Extravehicular Mobility Unit, or xEMU for short.

While the spacesuit is still under development, its features have been finalised. It’s already being tested underwater, and orbital testing is scheduled for 2023. Take a look:

1. Can extreme withstand temperatures of −250 degrees Fahrenheit in shade and up to 250 degrees Fahrenheit in the sun.

Electricity from the coldness of the universe

Posted by in categories: computing, physics, solar power, space, sustainability

The obvious drawback of solar panels is that they require sunlight to generate electricity. Some have observed that for a device on Earth facing space, which has a frigid temperature, the chilling outflow of energy from the device can be harvested using the same kind of optoelectronic physics we have used to harness solar energy. New work, in a recent issue of Applied Physics Letters, from AIP Publishing, looks to provide a potential path to generating electricity like solar cells but that can power electronics at night. For more information see the IDTechEx report on Energy Harvesting Microwatt to Megawatt 2019–2029.

An international team of scientists has demonstrated for the first time that it is possible to generate a measurable amount of electricity in a diode directly from the coldness of the universe. The infrared semiconductor device faces the sky and uses the temperature difference between Earth and space to produce the electricity.

“The vastness of the universe is a thermodynamic resource,” said Shanhui Fan, an author on the paper. “In terms of optoelectronic physics, there is really this very beautiful symmetry between harvesting incoming radiation and harvesting outgoing radiation.”

Energy-harvesting design aims to turn Wi-Fi signals into usable power

Posted by in categories: internet, mobile phones, physics

Any device that sends out a Wi-Fi signal also emits terahertz waves —electromagnetic waves with a frequency somewhere between microwaves and infrared light. These high-frequency radiation waves, known as “T-rays,” are also produced by almost anything that registers a temperature, including our own bodies and the inanimate objects around us.

Terahertz waves are pervasive in our daily lives, and if harnessed, their concentrated power could potentially serve as an alternate source. Imagine, for instance, a cellphone add-on that passively soaks up ambient T-rays and uses their energy to charge your phone. However, to date, waves are wasted energy, as there has been no practical way to capture and convert them into any usable form.

Now physicists at MIT have come up with a blueprint for a they believe would be able to convert ambient terahertz waves into a , a form of electricity that powers many household electronics.

Physicists develop new photon source for tap-proof communication

Posted by in categories: encryption, quantum physics, space

An international team with the participation of Prof. Dr. Michael Kues from the Cluster of Excellence PhoenixD at Leibniz University Hannover has developed a new method for generating quantum-entangled photons in a spectral range of light that was previously inaccessible. The discovery can make the encryption of satellite-based communications much more secure in the future.

A 15-member research team from the U.K., Germany and Japan has developed a new method for generating and detecting quantum-entangled photons at a wavelength of 2.1 micrometers. In practice, entangled photons are used in encryption methods such as quantum key distribution to completely secure telecommunications between two partners against eavesdropping attempts. The research results are presented to the public for the first time in the current issue of Science Advances.

It has been regarded as technically possible to implement encryption mechanisms with entangled photons in the near-infrared range of 700 to 1550 nanometers. However, these have disadvantages, especially in satellite-based communication. They are disturbed by light-absorbing gases in the atmosphere as well as the background radiation of the sun. With existing technology, end-to-end encryption of transmitted data can only be guaranteed at night, but not on sunny and cloudy days.
