White Holes: The Antithesis of Black Holes

Posted by in category: cosmology

We can consider white holes and black holes to be the two sides of the same coin. A perfect pair of antonyms. White holes first found their place, like many others, in Einstein’s theory of relativity. But it was left just there until theorists began pondering over its existence quite recently.

What is a white hole?

Insight, a white hole looks exactly like a black hole. It has mass, probably a ring of dust and gas around it. But the similarities end there. According to Carlo Ravelli, a theoretical physicist at the Centre de Physique Theorique in France, “It’s only in the moment when things come out that you can say, ‘ah, this is a white hole,”.

Sonic Black Holes Could Let Us Finally Understand One of the Biggest Mysteries in Physics

Posted by in categories: cosmology, physics

There can be other kinds of black holes that trap other physical phenomena, like sound waves, and these kinds of black holes, known as sonic black holes, might be critical to understanding their light-consuming counterparts in the wider universe.

Most important of all, what can sonic black holes tell us about one of modern physics’ most contentious debates, the so-called Information Paradox? A recent study attempted to find out, and its results seem to make the problem more complicated, not less.

Intel unveils second-generation neuromorphic computing chip

Posted by in category: computing

Intel today announced a major update to its neuromorphic computing program, including a second-generation chip called Loihi 2 and Lava, an open-source framework for developing “neuro-inspired” applications. The company is now offering two Loihi 2-based neuromorphic systems — Oheo Gulch and Kapoho Point. They will be available through a cloud service to members of the Intel Neuromorphic Research Community (INRC) and Lava via GitHub for free.

Full Story:


Intel unveiled the second generation of its neuromorphic chip and claims it will be able to solve planning and optimization problems.

Machine learning algorithm could provide Soldiers feedback

Posted by in categories: information science, military, robotics/AI

November 12 2020


RESEARCH TRIANGLE PARK, N.C. — A new machine learning algorithm, developed with Army funding, can isolate patterns in brain signals that relate to a specific behavior and then decode it, potentially providing Soldiers with behavioral-based feedback.

“The impact of this work is of great importance to Army and DOD in general, as it pursues a framework for decoding behaviors from brain signals that generate them,” said Dr. Hamid Krim, program manager, Army Research Office, an element of the U.S. Army Combat Capabilities Develop Command, now known as DEVCOM, Army Research Laboratory. “As an example future application, the algorithms could provide Soldiers with needed feedback to take corrective action as a result of fatigue or stress.”

NASA Readies for Future Artemis Moon Missions with Rocket Engine Test

Posted by in category: space travel

NASA marked a significant milestone Sept. 30 in its plans for future missions to the Moon and, eventually, Mars with completion of an RS-25 single-engine Retrofit-2 test series at Stennis Space Center near Bay St. Louis, Mississippi.


BepiColombo will complete its first of six Mercury flybys on October 1st. Some cameras will be operating so we’ll get some images. Some science, too.

BepiColombo Meets Mercury for the First Time on October 1

Posted by in category: space

BepiColombo will complete its first of six Mercury flybys on October 1st. Some cameras will be operating so we’ll get some images. Some science, too.


BepiColombo made a quick visit to Venus in August and is on to its next rendezvous. On October 1st it’ll perform a flyby of Mercury, the spacecraft’s eventual destination. This visit is just a little flirtation—one of six—ahead of its eventual orbital link-up with Mercury in late 2025.

Fractal Brain Networks Support Complex Thought

Posted by in category: neuroscience

Summary: When people engage in complex thoughts, their brain networks organize into fractal-like patterns.

Source: Dartmouth College.

Understanding how the human brain produces complex thought is daunting given its intricacy and scale. The brain contains approximately 100 billion neurons that coordinate activity through 100 trillion connections, and those connections are organized into networks that are often similar from one person to the next.

Brain-cleaning sleeping cap gets US Army funding

Posted by in categories: biotech/medical, neuroscience, wearables

Interesting.


Everybody knows sleep is important, but there’s still a lot we don’t understand about what it actually does to the brain – and how its benefits could be boosted. To investigate, the US Army has awarded researchers at Rice University and other institutions a grant to develop a portable skullcap that can monitor and adjust the flow of fluid through the brain during sleep.

Most of us are familiar with the brain fog that comes with not getting enough sleep, but the exact processes going on in there remain mysterious. In 2012 scientists made a huge breakthrough in the field by discovering the glymphatic system, which cleans out toxic waste products from the brain during deep sleep by flushing it with cerebrospinal fluid. Disruptions to sleep – and therefore the glymphatic system – have been increasingly associated with neurological disorders such as Alzheimer’s.
