Filament structure found to activate and regulate CRISPR-Cas ‘protein scissors’

Posted by in categories: biotech/medical, genetics

CRISPR-Cas systems help to protect bacteria from viruses. Several different types of CRISPR-Cas defense systems are found in bacteria, which differ in their composition and functions. Among them, the most studied proteins today are Cas9 and Cas12, also known as DNA or “gene scissors,” which have revolutionized the field of genome editing, enabling scientists to edit genomes and correct disease-causing mutations precisely.

Dockworkers are waging a battle against automation. The rest of us may want to take notes

Posted by in categories: economics, robotics/AI

The dockworkers striking up and down the East Coast are, culturally and geographically, a world apart from the Hollywood actors and writers who staged a four-month walkout last year. But their protests share a common core principle: They don’t want bots taking their jobs.

It’s a fight you can expect to see playing out a lot more as advanced automation and AI creep into virtually every workforce.

Here’s the deal: The East Coast port strike is getting a lot of attention for its potential disruption to the economy — which is precisely the point. Longshore work can be grueling, and the people working at ports are vital to getting all of the stuff we want to buy onto store shelves. No dockworkers means no bananas (or whatever), which means no profits for the companies that produce and ship them.

The Quest for True AI Consciousness — From the Turing Test to Consciousness 2.0

Posted by in category: robotics/AI

In the ongoing journey to create and understand AI (artificial intelligence), a key challenge has been determining if and when a machine has achieved consciousness.

While early AI research focused on mimicking human behavior, modern advancements have revealed the limitations of traditional evaluations like the Turing Test.

As we push the boundaries of AI development, we must redefine how we measure machine intelligence, moving beyond surface-level interactions to explore deeper levels of awareness, creativity and self-consciousness.

Microtubules and Consciousness: Exploring Energy Transfer and Quantum Theories

Posted by in categories: biological, neuroscience, quantum physics

Send us a text.

Put simply, the brain is not too warm or wet for consciousness to exist as a wave that connects with the universe.

For decades, Penrose has been working with anesthesiologist Stuart Hameroff on a theory of consciousness called Orchestrated Objective Reduction (Orch OR). Penrose primarily handles the physics of Orch OR, whereas Hameroff handles the biology. Their theory addressed serious gaps in established scientific frameworks spanning physics, neuroscience and psychology. All, some or none of the hypotheses in this theory might prove out experimentally. See the paper below as a step towards proof.

Webb Telescope Unveils New Chemical Insights on Pluto’s Moon Charon

Posted by in categories: chemistry, evolution, particle physics, space

What secrets can Pluto’s moon, Charon, reveal about the formation and evolution of planetary bodies throughout the solar system? This is what a recent study published in Nature Communications hopes to address as an international team of researchers led by the Southwest Research Institute (SwRI) used NASA’s James Webb Space Telescope (JWST) to conduct the first-time detection of hydrogen peroxide and carbon dioxide on Charon’s surface, which adds further intrigue to this mysterious moon, along with complementing previous discoveries of water ice, ammonia-bearing species, and organic materials, the last of which scientists hypothesize could explain Charon’s gray and red surface colors.

“The advanced observational capabilities of Webb enabled our team to explore the light scattered from Charon’s surface at longer wavelengths than what was previously possible, expanding our understanding of the complexity of this fascinating object,” said Dr. Ian Wong, who is a staff scientist at the Space Telescope Science Institute and a co-author on the study.

Detecting hydrogen peroxide is significant since it forms from the broken-up oxygen and hydrogen atoms after water ice is exposed to cosmic rays, solar wind, or solar ultraviolet light. This indicates that the Sun’s activity influences surface processes so far away, with Charon being approximately 3.7 billion miles from the Sun. The researchers determined that Charon’s carbon dioxide serves as a light coating on Charon’s water-ice heavy surface. While the surface of Charon was studied in-depth from NASA’s New Horizons mission in 2015, these new findings provide greater understanding of the physics-based processes responsible for Charon’s unique surface features.

Artificial left ventricle mimics the shape and function of the human heart

Posted by in category: biotech/medical

A team of biomechanical engineers at the University of New South Wales, working with a colleague from Queensland University of Technology and cardiac surgeons at St Vincent’s Hospital, Sydney, has developed an artificial human heart left ventricle (LV) that can be used for training heart surgeons and other doctors.

Sharpest Image Of Earth’s Radiation Belt Taken By NASA Shows Hot Plasma Encircling The Planet

Posted by in category: space travel

The Jupiter Icy Moons Explorer (JUICE) mission run by the European Space Agency (ESA) has taken the sharpest images ever produced of the Earth’s radiation belt. JUICE has a long mission ahead of it. Launched in April 2023, the spacecraft has to make several gravitational assists before it reaches its target of Jupiter and three of its largest moons…

Formation of Super-Earths is Limited Near Metal-Poor Stars — New study may help the search for life beyond Earth

Posted by in categories: alien life, solar power

In a new study, astronomers report novel evidence regarding the limits of planet formation, finding that after a certain point, planets larger than Earth have difficulty forming near low-metallicity stars.

Using the sun as a baseline, astronomers can measure when a star formed by determining its metallicity, or the level of heavy elements present within it. Metal-rich stars or nebulas formed relatively recently, while metal-poor objects were likely present during the early universe.

Previous studies found a weak connection between metallicity rates and planet formation, noting that as a star’s metallicity goes down, so, too, does planet formation for certain planet populations, like sub-Saturns or sub-Neptunes.
