Western Japan’s Sakurajima volcano erupts —weather agency

Posted by in category: climatology

A volcano on Japan’s western major island of Kyushu, called Sakurajima, erupted at about 8:05 p.m. (1105 GMT) on Sunday, the Japanese Meteorological Agency (JMA) said, but media said there were no immediate reports of damage.

There were reports of volcanic stones raining down at a distance of 2.5 km (1.5 miles) from the volcano, NHK public television said. The eruption alert level has been raised to 5, the highest, with some areas advised to evacuate, NHK said. Sakurajima is one of Japan’s most active volcanoes and eruptions of varying levels are frequent. In 2019 it spewed ash 5.5 km (3.4 miles) high.

Amazing James Webb image looks like a wormhole

Posted by in category: cosmology

Early data from the James Webb Space Telescope is already starting to come in, with exciting finds like views of Jupiter and a potential sighting of the most distant galaxy ever observed. But there’s a lot more Webb data being shared, and much of it is publicly available through the Space Telescope Science Institute’s MAST archive. That means enterprising astronomers are already digging through James Webb data to perform their own analyses, and have created some amazing visuals.

Gabriel Brammer, an associate professor at the University of Copenhagen, composed and shared this incredible and faintly terrifying image on Twitter. It shows the galaxy Messier 74, captured in the mid-infrared range by Webb’s MIRI instrument as part of the PHANGS-JWST project.

“Let’s just see what JWST observed yesterday …” Brammer wrote on Twitter. Then, echoing all of our sentiments, “Oh, good god.”

The world of technology is rapidly shifting from flat media viewed in the third person to immersive media experienced in the first person. Recently dubbed “the metaverse,” this major transition in mainstream computing has ignited a new wave of excitement over the core technologies of virtual and augmented reality. But there is a third technology area known as telepresence that is often overlooked but will become an important part of the metaverse.

Community Newsletter: An ‘unexpected autistic,’ presynaptic optogenetics, neuroanatomy art

Posted by in categories: genetics, neuroscience

Heating up Twitter feeds this week was a new commentary about a rarely discussed perspective on autism, talk about the use of optogenetics tools to manipulate ‘presynapses,’ a possible explanation for decision-making differences between the sexes, and a striking illustration of the human brain.

Reality doesn’t exist until you measure it, quantum parlor trick confirms

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

😳!!!


The Moon isn’t necessarily there if you don’t look at it. So says quantum mechanics, which states that what exists depends on what you measure. Proving reality is like that usually involves the comparison of arcane probabilities, but physicists in China have made the point in a clearer way. They performed a matching game in which two players leverage quantum effects to win every time—which they can’t if measurements merely reveal reality as it already exists.

“To my knowledge this is the simplest [scenario] in which this happens,” says Adan Cabello, a theoretical physicist at the University of Seville who spelled out the game in 2001. Such quantum pseudotelepathy depends on correlations among particles that only exist in the quantum realm, says Anne Broadbent, a quantum information scientist at the University of Ottawa. “We’re observing something that has no classical equivalent.”

“The Crisis of the Day” Stated the U.S. Supreme Court When Ruling Against the EPA’s Oversight of the Environment

Posted by in categories: chemistry, climatology, sustainability

At the time climate change was only beginning to be talked about in the scientific community as well as behind the scenes among researchers working for fossil fuel companies.

Climate change fit the EPA’s mandate. And unlike an oil or chemical spill, no reputable scientist would see climate change as equivalent to “the crisis of the day.” But this phrase appears in Chief Justice John Roberts’ opinion justifying the decision in West Virginia v. EPA to deny the Agency its power to regulate carbon emissions from coal-fired power plants which based on the mandated powers described above is its purview (see points 3, 4, and 5).

Protein sequence design by deep learning

Posted by in categories: information science, robotics/AI, space

The design of protein sequences that can precisely fold into pre-specified 3D structures is a challenging task. A recently proposed deep-learning algorithm improves such designs when compared with traditional, physics-based protein design approaches.

ABACUS-R is trained on the task of predicting the AA at a given residue, using information about that residue’s backbone structure, and the backbone and AA of neighboring residues in space. To do this, ABACUS-R uses the Transformer neural network architecture6, which offers flexibility in representing and integrating information between different residues. Although these aspects are similar to a previous network2, ABACUS-R adds auxiliary training tasks, such as predicting secondary structures, solvent exposure and sidechain torsion angles. These outputs aren’t needed during design but help with training and increase sequence recovery by about 6%. To design a protein sequence, ABACUS-R uses an iterative ‘denoising’ process (Fig.
