‘Exhilarating’ implant turns thoughts to speech
“The mind-reading technology works in two stages. First an electrode is implanted in the brain to pick up the electrical signals that manoeuvre the lips, tongue, voice box and jaw. Then powerful computing is used to simulate how the movements in the mouth and throat would form different sounds. This results in synthesised speech coming out of a “virtual vocal tract”.”
The technology could eventually help those who have lost their voice to speak again.
Holotron presents a full-body exoskeleton for walking in VR
The full-body exoskeleton lets you feel and control all the forces your avatar feels.
The Holotron is a full-body exoskeleton, with several possible realizations for life-like control of any humanoid avatar, including implanted brain-computer interfaces.
Australian Radio Telescopes Just Completed a map of the Universe
CSIRO has made a detailed radio survey of the southern hemisphere, and discovered a million new galaxies.
Although radio astronomy has been around since the 1930s, it is only in recent years that astronomers have been able to make high-resolution maps of the radio sky. Sky maps are difficult for radio telescopes because radio antennas need to be focused on an extremely small patch of sky to capture images in high resolution. But with modern antennas and computer processing, we can now scan the sky quickly enough to map the heavens in a reasonable amount of time.
In the northern hemisphere, the most detailed radio sky maps have been done by the Very Large Array (VLA). In the 1990s the VLA made the first full-sky surveys of the northern sky. After its upgrade in the 2000s, the observatory began the VLA Sky Survey (VLASS), which has mapped nearly 10 million radio sources.
The location of the VLA lets it observe about 80% of the sky, but it cannot see the southern sky very well. For that, you’d need a radio observatory in the southern hemisphere. Fortunately, there is now a powerful radio telescope array in Australia, and it has recently made a detailed radio map.

Meshing Optics With Electronics: Physics Discovery Leads to Ballistic Optical Materials
Electronics are increasingly being paired with optical systems, such as when accessing the internet on an electronically run computer through fiber optic cables.
But meshing optics — which relies on particles of light called photons—with electronics—relying on electrons — is challenging, due to their disparate scales. Electrons work at a much smaller scale than light does. The mismatch between electronic systems and optical systems means that every time a signal converts from one to the other, inefficiency creeps into the system.
Now, a team led by a Purdue University scientist has found a way to create more efficient metamaterials using semiconductors and a novel aspect of physics that amplifies the activity of electrons. The study is published in the journal Optica.
Neuroscientists investigate the relationship between language and cognitive functions
In some ways, learning to program a computer is similar to learning a new language. It requires learning new symbols and terms, which must be organized correctly to instruct the computer what to do. The computer code must also be clear enough that other programmers can read and understand it.
In spite of those similarities, MIT neuroscientists have found that reading computer code does not activate the regions of the brain that are involved in language processing.
Instead, it activates a distributed network called the multiple demand network, which is also recruited for complex cognitive tasks such as solving math problems or crossword puzzles.
Entangled Photons Created 100 Times More Efficiently Than Previously Possible
Fast, ultra-bright photon source brings scalable quantum photonics within reach. Super-fast quantum computers and communication devices could revolutionize countless aspects of our lives — but first, researchers need a fast, efficient source of the entangled pairs of photons such systems use to tra.
Google Looks to Batteries as Replacement for Diesel Generators
O,.o.
Google will use large batteries to replace the diesel generators at one of its data centers in Belgium, describing the project as a first step towards using cleaner technologies to provide backup power for its millions of servers around the world.
“Our project in Belgium is a first step that we hope will lay the groundwork for a big vision: a world in which backup systems at data centers go from climate change problems to critical components in carbon-free energy systems,” said Joe Kava, Vice President for Data Centers at Google. “We’re aiming to demonstrate that a better, cleaner solution has advanced far enough to keep the internet up and running.”
Google becomes the second major hyperscale cloud operator to pursue a strategy to move beyond diesel generators. In July, Microsoft said it will eliminate its reliance on diesel fuel by the year 2030 and has begun testing hydrogen fuel cells as an alternative. These announcements have implications beyond company-built facilities, as Google and Microsoft are major tenants in third-party data centers, most of which use diesel generators for backup power.
