Peering Into the Abyss: AI and Physics Unite to Unveil a Black Hole Flare in 3D

Posted by in categories: cosmology, physics, robotics/AI

Using AI and ALMA data, scientists create a groundbreaking 3D video of flares around our galaxy’s central black hole, offering new insights into its dynamic environment.

Scientists believe the environment immediately surrounding a black hole is tumultuous, featuring hot magnetized gas that spirals in a disk at tremendous speeds and temperatures. Astronomical observations show that within such a disk, mysterious flares occur up to several times a day, temporarily brightening and then fading away. Now a team led by Caltech scientists has used telescope data and an artificial intelligence (AI) computer-vision technique to recover the first three-dimensional video showing what such flares could look like around Sagittarius A* (Sgr A*, pronounced sadge-ay-star), the supermassive black hole at the heart of our own Milky Way galaxy.

Breakthrough in Bioinformatics: AI Predicts Cell Type Transformations

Posted by in categories: biotech/medical, health, robotics/AI

Advances in gene sequencing technology and computing power have significantly increased the availability of bioinformatic data and processing capabilities. This convergence provides an ideal opportunity for artificial intelligence (AI) to develop methods to control cellular behavior.

In a new study, Northwestern University researchers have reaped fruit from this nexus by developing an AI-powered transfer learning approach that repurposes publicly available data to predict combinations of gene perturbations that can transform cell type or restore diseased cells to health.

The study was recently published in the Proceedings of the National Academy of Sciences.

Formation of memory assemblies through the DNA-sensing TLR9 pathway

Posted by in categories: biotech/medical, neuroscience

Learning results in persistent double-stranded DNA breaks, nuclear rupture and release of DNA fragments and histones within hippocampal CA1 neurons that, following TLR9-mediated DNA damage repair, results in their recruitment to memory circuits.

How spicy does mustard get depending on the soil?

Posted by in category: futurism

Serious wine drinkers often have their preferences: Some prefer sweet hints of chocolate in a Malbec from Argentina, while others are drawn to a spicy and fruity Cabernet Sauvignon from Napa Valley. Wine connoisseurs firmly believe that the soil in which grapes are grown determines how it tastes.

Generative A.I. Arrives in the Gene Editing World of CRISPR

Posted by in categories: bioengineering, biotech/medical, robotics/AI

Generative A.I. technologies can write poetry and computer programs or create images of teddy bears and videos of cartoon characters that look like something from a Hollywood movie.

Now, new A.I. technology is generating blueprints for microscopic biological mechanisms that can edit your DNA, pointing to a future when scientists can battle illness and diseases with even greater precision and speed than they can today.

Witnessing the Birth of Skyrmions

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

Using thin layers of chiral nematic liquid crystals, researchers have observed the formation dynamics of skyrmions.

A skyrmion is a topologically stable, vortex-like field configuration that cannot be smoothly morphed to a uniform state [1]. First proposed by physicist Tony Skyrme in 1961 as a model of the nucleon [2], the concept has since been studied in condensed-matter physics and adjacent fields [3]. In particular, skyrmions have cropped up in studies of magnetism [4], Bose-Einstein condensates [5], quantum Hall systems [6], liquid crystals [7], and in other contexts (see, for example, Viewpoint: Water Can Host Topological Waves and Synopsis: Skyrmions Made from Sound Waves). Skyrmions exhibit fascinating properties such as small size, stability, and controllability, which give them great potential for applications in spintronics, data storage, and quantum computing.
