See how dormant potential energy explodes in psychedelic swirls when chemicals meet by combining oils, alcohols and inks in Petri dishes. Via the dazzling, colourful patterns that emerge, Gatti draws a line back to the surface of the Sun, where the constant churn of a volatile chemical reaction makes life on Earth possible.
Physicists with the Harvard-MIT Center for Ultracold Atoms have just announced new success with a particular style of quantum computer —a “programmable quantum simulator”. In this architecture, they take supercold rubidium atoms and use optical tweezers (beams of light) to arrange the atoms into shapes.
As the Harvard Gazette writes …
This new system allows the atoms to be assembled in two-dimensional arrays of optical tweezers. This increases the achievable system size from 51 to 256 qubits. Using the tweezers, researchers can arrange the atoms in defect-free patterns and create programmable shapes like square, honeycomb, or triangular lattices to engineer different interactions between the qubits.
Black holes are getting weirder by the day. When scientists first confirmed the behemoths existed back in the 1970s, we thought they were pretty simple, inert corpses. Then, famed physicist Stephen Hawking discovered that black holes aren’t exactly black and they actually emit heat. And now, a pair of physicists has realized that the sort-of-dark objects also exert a pressure on their surroundings.
The finding that such simple, non-rotating “black holes have a pressure as well as a temperature is even more exciting given that it was a total surprise,” co-author Xavier Calmet, a professor of physics at the University of Sussex in England, said in a statement.
Earlier this year, two astronomers discovered what could be the largest comet ever seen in the solar system while combing through data collected by the Dark Energy Survey. Now, a new study led by the same scientists describes this beefy deep space monster as the “nearly spherical cow of comets.”
The comet is cataloged as Comet C/2014 UN271 but is also known as Comet Bernardinelli-Bernstein for its discovery duo, Pedro Bernardinelli and Gary Bernstein, both from the University of Pennsylvania.

New chip eliminates the need for specific decoding hardware, could boost efficiency of gaming systems, 5G networks, the internet of things, and more.
A new silicon chip can decode any error-correcting code through the use of a novel algorithm known as Guessing Random Additive Noise Decoding (GRAND). The work was led by Muriel Médard, an engineering professor in the MIT Research Laboratory of Electronics.

Depression is a serious medical condition that plagues modern society. Several theories have been proposed to explain the physiological basis of depression, of which the “neurogenic hypothesis of depression” has garnered much attention.
To use the metaphor of our Information Age, consciousness to humans is as Cloud to computers. Just like your smartphone, your brain is a ‘bio’-logical computing device of your mind, an interface for physical reality. Our minds are connected into the greater mind-network, as computers in the Cloud. Viewed in this way, consciousness is ‘non-local’ Cloud, our brain-mind systems are receivers, processors and transmitters of information within that Cloud. What were the most significant factors in evolution of the human mind? What’s the connection between quantum physics and consciousness? What role does quantum information play in our self-reflective consciousness? What is non-local consciousness? Do our minds create reality? These are some of the most salient questions addressed in this Part II of the documentary.

Back to Aliens, we find “Building Better Worlds” as the main slogan of the nefarious Weyland-Yutani Corporation. Apparently, terraforming (and presumably mining) celestial bodies is a large part of their galactic business. When acid hits the fan and the xenomorphs take over Hadley’s Hope, their operations on LV-426 have been active for decades. But is that enough time for Acheron (formally labelled as LV-426) to develop a breathable atmosphere?
The film itself doesn’t have many answers when it comes to terraforming, but the procedure appears to revolve around reutilizing the existing atmosphere – breaking down pre-existing elements, transforming, and redistributing them – instead of starting from scratch, which would indeed take centuries. Basically, mankind can’t turn any planet or planetoid into an Earth-like environment in the Alien universe; most components need to be present already, same goes for the atmospheric conditions. This fixes the centuries-long problem that comes up in other works of fiction, or at least makes the storytelling more realistic.
Complementary material detailing the Alien universe’s history and technology claim the first “Automated Atmosphere Processor” became a reality in 2,029 with a first terraforming process happening on Gliese 667 Cc during the 2030s and ending around 2040. The Weyland Corp Terraforming Division was created in 2,072 effectively starting a new age of space exploration. As stated before, native atmospheres are transformed thanks to the company’s “Atmosphere Processing Plants” and other techniques, such as algae bloom tanks that consume excess carbon dioxide and generate oxygen. It all depends on the properties of planets which have been previously scouted, inspected, and approved for viable terraformation.
Back in 2,014 the World Health Organization (WHO) warned that within a decade, antibiotic-resistant bacteria could make routine surgery, organ transplantation, and cancer treatment life-threateningly risky — and spell the end of modern medicine as we know it.
Antibiotics are a cornerstone of modern medicine, used to treat infections and to protect vulnerable patients undergoing surgery or chemotherapy. The world desperately needs new antibiotics, and Covid-19 has only exacerbated the problem.
