With the help of ESO’s Very Large Telescope (VLT), astronomers have found six galaxies lying around a supermassive black hole when the Universe was less than a billion years old. This is the first time such a close grouping has been seen so soon after the Big Bang and the finding helps us better understand how supermassive black holes, one of which exists at the centre of our Milky Way, formed and grew to their enormous sizes so quickly. It supports the theory that black holes can grow rapidly within large, web-like structures which contain plenty of gas to fuel them.

“This research was mainly driven by the desire to understand some of the most challenging astronomical objects —supermassive black holes in the early Universe. These are extreme systems and to date we have had no good explanation for their existence,” said Marco Mignoli, an astronomer at the National Institute for Astrophysics (INAF) in Bologna, Italy, and lead author of the new research published today in Astronomy & Astrophysics.

The new observations with ESO’s VLT revealed several galaxies surrounding a supermassive black hole, all lying in a cosmic “spider’s web” of gas extending to over 300 times the size of the Milky Way. “The cosmic web filaments are like spider’s web threads,” explains Mignoli. “The galaxies stand and grow where the filaments cross, and streams of gas—available to fuel both the galaxies and the central supermassive black hole—can flow along the filaments.”

Researchers have created a way for artificial neuronal networks to communicate with biological neuronal networks. The new system converts artificial electrical spiking signals to a visual pattern than is then used to entrain the real neurons via optogenetic stimulation of the network. This advance will be important for future neuroprosthetic devices that replace damages neurons with artificial neuronal circuitry.

A prosthesis is an artificial device that replaces an injured or missing part of the body. You can easily imagine a stereotypical pirate with a wooden leg or Luke Skywalker’s famous robotic hand. Less dramatically, think of old-school prosthetics like glasses and contact lenses that replace the natural lenses in our eyes. Now try to imagine a prosthesis that replaces part of a damaged brain. What could artificial brain matter be like? How would it even work?

Creating neuroprosthetic technology is the goal of an international team led by by the Ikerbasque Researcher Paolo Bonifazi from Biocruces Health Research Institute (Bilbao, Spain), and Timothée Levi from Institute of Industrial Science, The University of Tokyo and from IMS lab, University of Bordeaux. Although several types of artificial neurons have been developed, none have been truly practical for neuroprostheses. One of the biggest problems is that neurons in the brain communicate very precisely, but electrical output from the typical electrical neural network is unable to target specific neurons. To overcome this problem, the team converted the electrical signals to light. As Levi explains, “advances in optogenetic technology allowed us to precisely target neurons in a very small area of our biological neuronal network.”

In a recent study, scientists have made an unprecedented discovery: crows are not only clever; they also show consciousness and are aware of the world around them. This means they also have experiences that they feel and remember.

As per the research work published in the journal ‘Science’, researchers have discussed that crows show a primary or sensory consciousness. Such a form of consciousness was previously only found among primates before. This was the first time such a form of consciousness was recorded among a bird. Scientists believe this study will pave the path for researchers to understand better the evolution of awareness among the different living beings and how it affects the brain and thinking capacity among the various organisms.

It is difficult to understand the extent of consciousness, especially concerning birds because they do not speak the way we do, nor do we have sophisticated instruments to understand what goes inside their heads. Consciousness involves the thought process behind self-awareness and awareness of the world around oneself. With a good conscience, an individual often shows problem-solving traits and good decision-making skills – some visible strategies, both at which crows are good.

Most neurons in the human brain are generated from neural stem cells during embryonic development. After birth, a small reservoir of stem cells remains in the brain that keeps on producing new neurons throughout life. However, the question arises as to whether these new neurons really support brain function? And if so, can we improve brain capacity by increasing the number of neurons? The research group of Prof. Federico Calegari at the Center for Regenerative Therapies Dresden (CRTD) of TU Dresden has answered these questions, now published in the EMBO Journal.

In their latest study, the scientists analysed healthy adult mice in which the small reservoir of stem cells was manipulated in order to increase in number. As a result, the number of neurons, generated from these stem cells, also increased. In mice, these neurons mainly populate the brain area responsible for interpreting odours. In fact, olfaction is one to the most powerful senses in mice, fundamental for finding food and escape from predators. As powerful as the sense of smell naturally is in mice, in the following behavioural experiments the scientists found that mice with more neurons were able to distinguish extremely similar odours that normal mice failed to. Hence, this study is fundamental in proving that stem cells can be used to improve brain function.

“Evolution gave mice an extremely sensitive olfactory system. It is amazing that by adding few neurons we could improve something that seemed already close to perfection,” states Prof. Federico Calegari. “This study sets the basis for our research, which now is focused on finding out whether we could apply our strategy as a therapeutic approach in neurodegenerative models.”

The Moringa tree has been nicknamed ‘The Miracle Tree’ because it is a significant source of fats, proteins, crotonoids, vitamin C, iron, potassium, and other nutrients. The flowers, roots, and bark of the tree are a source for use in nutritional supplements and are also used for cosmetics, toiletries and skin oils.

This places Drake in the company of towering physicists with equations named after them, including James Clerk Maxwell and Erwin Schrödinger. Unlike those, Drake’s equation does not encapsulate a law of nature. Instead, it combines some poorly known probabilities into an informed estimate.

Whatever reasonable values you feed into the equation (see image below), it is hard to avoid the conclusion that we shouldn’t be alone in the galaxy. Drake remained a proponent and a supporter of the search for extraterrestrial life throughout his days, but has his equation taught us anything?

The most powerful Exascale Supercomputer is going to release in 2021 and will feature a total of 64 Exaflops. More than 6 times as much, as the Leonardo Supercomputer that’s also set to release this year.
This is accomplished with the help of a new type of processor technology from Tachyum that’s called “Prodigy” and is described as the first Universal Processor.

This new processor is set to enable General Artificial Intelligence at the speed of the human brain in real-time. It’s many times faster than the fastest intel xeon, nvidia graphics card or apple silicon. This new super-computer will enable previously-thought impossible simulations of the brain, medicine and more.
