A US company just deployed world’s largest communication satellite

Posted by in categories: internet, satellites

The 693-square-foot array is designed to provide 5G broadband connectivity directly with cellular devices via 3GPP standard frequencies.

Bluewalker 3 satellite, a test satellite by Texas-based firm AST SpaceMobile deployed its largest commercial communications array ever flow in space, in low Earth orbit, the company announced on Monday. The satellite was launched on a SpaceX Falcon 9 rocket in September, Interesting Engineering.

AI predicts that a dinosaur thought to be predatory may have been an herbivore

Posted by in category: robotics/AI

It’s commonly believed that many of these prehistoric animals were vicious carnivores.

Researchers used artificial intelligence (AI) to discover information on dinosaurs, specifically to find out if a certain dinosaur was a predator or not. AI has shown that the dinosaur typically thought to be a carnivore may actually have been an herbivore.

The new analysis was done by using deep convolutional neural networks (DCNNs) — computing systems based on neural networks of the brain — to track the fossils of these prehistoric reptiles.

Limitless nuclear fusion energy is one step closer thanks to burning plasma experiment

Posted by in categories: nuclear energy, physics

We could be a step closer to the commercially viable production of limitless nuclear fusion energy.

A group of nuclear fusion researchers at the National Ignition Facility (NIF) achieved self-heating “burning plasma” for the first time ever in January, bringing commercially viable nuclear fusion one step closer.

Now, a new analysis of the plasma, published in a paper in the journal Nature Physics, reveals surprising new details that could help the scientific community finally achieve the holy grail of nuclear fusion — net energy production.

Artificial light at night might be the cause of diabetes in more than 9 million Chinese adults

Posted by in category: biotech/medical

The new study found a correlation between outdoor artificial light at night (LAN) and higher rates of diabetes.

According to a new study, exposure to outdoor artificial light at night (LAN) is associated with an increased risk of diabetes, along with impaired glucose control.

The world’s population has reached 8 billion and counting

Posted by in categories: biotech/medical, health

A result of the gradual increase in human lifespan and high and persistent levels of fertility in some countries.

The world’s population hit eight billion today, November 15, and this is a “milestone in human development,” according to a statement by the United Nations (UN).

This unprecedented growth is due to the gradual increase in human lifespan owing to improvements in public health, nutrition, personal hygiene, and medicine.

Effective Philanthropy: That’s what Jeff Bezos wants to do with his $122 billion fortune

Posted by in category: Elon Musk

Bezos thinks that there are many ineffective ways of philanthropy and wants to avoid them as he prepares to give away all his wealth.

Amazon founder Jeff Bezos told during a short interview with CNN

With this announcement, Bezos joins the list of other billionaires in the world, such as Bill Gates, who have decided to give away their wealth during their lifetimes. After expressing his desire to remove himself from the list of billionaires, Gates donated $6 billion to his Foundation, which runs programs across the world.

Scientists Created a Black Hole in The Lab, And Then It Started to Glow

Posted by in categories: cosmology, mathematics, particle physics, quantum physics

A new kind of black hole analog could tell us a thing or two about an elusive radiation theoretically emitted by the real thing.

Using a chain of atoms in single-file to simulate the event horizon of a black hole, a team of physicists has observed the equivalent of what we call Hawking radiation – particles born from disturbances in the quantum fluctuations caused by the black hole’s break in spacetime.

This, they say, could help resolve the tension between two currently irreconcilable frameworks for describing the Universe: the general theory of relativity, which describes the behavior of gravity as a continuous field known as spacetime; and quantum mechanics, which describes the behavior of discrete particles using the mathematics of probability.

Wormholes May Already Have Been Detected, Physicists Say

Posted by in categories: cosmology, physics

Hypothetical bridges connecting distant regions of space (and time) could more or less look like garden variety black holes, meaning it’s possible these mythical beasts of physics have already been seen.

Thankfully however, if a new model proposed by a small team of physicists from Sofia University in Bulgaria is accurate, there could still be a way to tell them apart.

Play around with Einstein’s general theory of relativity long enough, it’s possible to show how the spacetime background of the Universe can form not only deep gravitational pits where nothing escapes – it can form impossible mountain peaks which can’t be climbed.
