The James Webb Space Telescope finishes unfolding its primary mirror, concluding major deployments

Posted by in category: space

The James Webb Telescope (JWST) has finished unfolding its primary mirror, ending a series of major deployments that took place over the span of two weeks. All of those deployments needed to go perfectly in order for the massive space telescope, which was decades in the making, to function.

The JWST has two primary mirror panels on either side that it will use to collect infrared light from the distant Universe. Each of them consists of three gold-plated hexagonal mirrors. Today, the rightmost wing was successfully unfurled, just one day after the leftmost wing was deployed. Now that both sides have been locked into place, this completes the array of 18 mirrors that makes up the 21-foot-wide JWST.

Congratulations, @NASAWebb! You are fully deployed!

Researchers Use Machine Learning To Repair Genetic Damage

Posted by in categories: biotech/medical, genetics, life extension, robotics/AI

DNA damage is constantly occurring in cells, either due to external sources or as a result of internal cellular metabolic reactions and physiological activities. Accurate repair of such DNA damages is critical to avoid mutations and chromosomal rearrangements linked to diseases including cancer, immunodeficiencies, neurodegeneration, and premature aging.

A team of researchers at Massachusetts General Hospital and the National Cancer Research Centre have identified a way to repair genetic damage and prevent DNA alterations using machine learning techniques.

The researchers state that it is possible to learn more about how cancer develops and how to fight it if we understand how DNA lesions originate and repair. Therefore, they hope that their discovery will help create better cancer treatments while also protecting our healthy cells.

Hawking radiation mimicked in the lab

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

Circa 2014


Scientists have come closer than ever before to creating a laboratory-scale imitation of a black hole that emits Hawking radiation, the particles predicted to escape black holes due to quantum mechanical effects.

The black hole analogue, reported in Nature Physics1, was created by trapping sound waves using an ultra cold fluid. Such objects could one day help resolve the so-called black hole ‘information paradox’ — the question of whether information that falls into a black hole disappears forever.

3D-printed home cuts construction time from 4 weeks to 28 hours, says Habitat for Humanity

Posted by in categories: 3D printing, economics, habitats

Virginia mom April Stringfield is now the owner of Habitat for Humanity’s first 3D-printed home — built in record time, thanks to new construction tech.

The massive time and money savings from 3D printing means the nonprofit is very likely to print more in the future.

Super-Resolution Imaging of a Single Cold Atom on a Nanosecond Timescale

Posted by in category: particle physics

The team of academician GUO Guangcan of University of Science and Technology of China (USTC) of the Chinese Academy of Sciences has made important progress in the research of cold atom.

An atom is the smallest component of an element. It is made up of protons and neutrons within the nucleus, and electrons circling the nucleus.

‘We don’t need to work anymore’: Local artists crack the code of NFTs

Posted by in categories: blockchains, cybercrime/malcode, employment, finance

Such is the promise and peril of NFTs.

NFTs, or non-fungible tokens, offer many potential benefits to creators. They apply the mechanisms of scarcity to digital assets by allowing artists to render them as one-of-a-kind collectibles, like a painting or a baseball card. This means artists — especially digital artists — who have struggled to make their streamable, screenshot-able or reprintable work hold value — can price their items at rates appropriate for something in short supply.

However, the digital trading mechanism is still in nascent stages, and rife with scams, hacks and copyright issues. Beeple was hit by an organized hack, for example. While artists can sometimes find financial solvency with NFTs, other times, they lose millions.

A better black hole laser may prove a circuitous ‘Theory of Everything’

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

😮 circa 2021.


The fundamental forces of physics govern the matter comprising the Universe, yet exactly how these forces work together is still not fully understood. The existence of Hawking radiation — the particle emission from near black holes — indicates that general relativity and quantum mechanics must cooperate. But directly observing Hawking radiation from a black hole is nearly impossible due to the background noise of the Universe, so how can researchers study it to better understand how the forces interact and how they integrate into a “Theory of Everything”?
