Theories on how the Milky Way formed are set to be rewritten following discoveries about the behavior of some of its oldest stars.

An investigation into the orbits of the Galaxy’s metal-poor stars—assumed to be among the most ancient in existence—has found that some of them travel in previously unpredicted patterns.

“Metal-poor stars—containing less than one-thousandth the amount of iron found in the Sun—are some of the rarest objects in the galaxy,” said Professor Gary Da Costa from Australia’s ARC Center of Excellence in All Sky Astrophysics in 3 Dimensions (ASTRO 3D) and the Australian National University.

There is some precedent for international treaties regarding the exploration of other worlds, most-notably the Outer Space Treaty of 1976 or the Artemis Accords. But these amount to little more than non-aggression pacts. The COSPAR convention came closer to what is needed by declaring the inherent hazards to science and terrestrial life that go with exploring other worlds. However, at present, such documents merely recommendations to governments and industry. There are no current means for enforcing the guidelines.

Elon Musk, the founder of SpaceX, talks with Commercial Crew astronauts and the current NASA Administrator, Jim Bridenstine. The merger between the public and private sectors of the aerospace industry is seen clearly with the partnership between NASA and SpaceX, as it was the first private company to bring American astronauts to the International Space Station.

Bryna Kra searches for the patterns in sequences of numbers that explain how complicated dynamical systems evolve over time.

In their paper published in Frontiers of Physics, Franco Vazza (astrophysicist at the University of Bologna) and Alberto Feletti (neurosurgeon at the University of Verona) investigated the similarities between two of the most challenging and complex systems in nature: the cosmic network of galaxies and the network of neuronal cells in the human brain.

Despite the substantial difference in scale between the two networks (more than 27 orders of magnitude), their quantitative analysis, which sits at the crossroads of cosmology and neurosurgery, suggests that diverse physical processes can build structures characterized by similar levels of complexity and self-organization.

The human brain functions thanks to its wide neuronal network that is deemed to contain approximately 69 billion neurons. On the other hand, the observable universe can count upon a cosmic web of at least 100 billion galaxies. Within both systems, only 30% of their masses are composed of galaxies and neurons. Within both systems, galaxies and neurons arrange themselves in long filaments or nodes between the filaments. Finally, within both systems, 70% of the distribution of mass or energy is composed of components playing an apparently passive role: water in the brain and dark energy in the observable Universe.

Small, boxy satellites are ridesharing their way into outer space—and may lead to important advances in laser communications and cybersecurity.

NVIDA has surpassed the 2 terabyte-per-second memory bandwidth mark with its new GPU, the Santa Clara graphics giant announced Monday.

The top-of-the-line A100 80GB GPU is expected to be integrated in multiple GPU configurations in systems during the first half of 2021.

Earlier this year, NVIDIA unveiled the A100 featuring Ampere architecture, asserting that the GPU provided “the largest leap in performance” ever in its lineup of graphics hardware. It said AI training on the GPU could see performance boosts of 20 times the speed of its earlier generation units.

The world’s first restaurant experience that provides clientele the opportunity to eat meat grown directly from chicken cells has been opened in the Israeli town of Ness Ziona.

Like walking and breathing and could one day allow people to control prosthetics simply by thinking…

The US Army is funding a project that could lead to brain-machine interfaces. It includes an algorithm capable of isolating brain signals and linking them to specific behaviors such as walking and breathing.

Scientists have detected two bright radio bursts from a magnetar in our galaxy, as they get closer to discovering the source of the blasts.

Earlier this month, scientists discovered that fast radio bursts were coming from the object, in a major breakthrough in the search for the source of those mysterious blasts of energy. It was the first time an FRB had been detected coming from inside our Milky Way, and also the first time such a blast had been traced back to a particular source.

Now scientists say they have found new bursts coming from that same magnetar. That should help further indicate whether it is really a source of FRBs – and whether the same process could be powering those bursts we have discovered coming from elsewhere in the universe.
