Super-bright black holes could reveal if the universe is pixelated
Posted by Dan Breeden in category: cosmology
Space-time may not be continuous but instead made up of many discrete bits – and we may be able to see their effects near the edges of unusually bright black holes.

Nanotechnology: A potential cure for incurable diseases
Posted by Dan Breeden in categories: biotech/medical, nanotechnology, neuroscience
Nanotechnology is poised to transform neurological disorder treatments by overcoming the blood-brain barrier, enabling effective medication delivery for conditions like dementia and Alzheimer’s. This innovative approach also shows promise in dermatology and cancer treatment, enhancing drug absorption and targeting, while minimizing side effects. Experts at AIIMS highlighted ongoing research and potential breakthroughs expected in the next few years.

Asymmetric dearomative single-atom skeletal editing of indoles and pyrroles
Posted by Dan Breeden in category: biotech/medical
Skeletal editing has emerged as an appealing strategy for scaffold-hopping-based drug discovery, but the enantioselective single-atom skeletal editing of N-heteroarenes is challenging. Now, using trifluoromethyl N-triftosylhydrazones as carbene precursors, the enantiodivergent dearomative skeletal editing of indoles and pyrroles has been achieved through asymmetric carbon-atom insertion.
One day our Sun will die, and consume our world in fire, but is it possible to refuel our Sun so that it might live trillions and trillions of year to come?

What Your Brain Is Really Doing When You’re Doing ‘Nothing’: Default Mode Network
Posted by Shubham Ghosh Roy in category: neuroscience
When your mind is wandering, your brain’s “default mode” network (DMN) is active. Its discovery 20 years ago inspired a raft of research into networks of brain regions and how they interact with each other. New research, including a recent study of the brain on psilocybin, is revealing the default mode networks’s role in memory, social awareness and sense of self.

More than 40% of coral species face extinction, according to new research
Posted by Quinn Sena in categories: climatology, existential risks
Yikes o.o! What I believe is that we need to have cooling systems underwater to keep things cooler so coral and fish can survive. It could also mean even that fish food supplies could run out in the future from the ocean.
Following a global assessment, the IUCN Red List of Threatened Species has revealed that 44% of reef-building coral species globally are at risk of extinction. The announcement was made at the ongoing COP29 UN climate conference.
Dr. Michael Sweet, Professor of Molecular Ecology and Head of the Aquatic Research Facility at the University of Derby, is among a pool of experts who contributed to the global coral assessment, which has revealed the severe impacts of our rapidly changing climate.

3D-Printed Solutions Shield Electronics from Electrostatic Discharge
Posted by Natalie Chan in categories: 3D printing, chemistry
Electrostatic discharge (ESD) protection is a significant concern in the chemical and electronics industries. In electronics, ESD often causes integrated circuit failures due to rapid voltage and current discharges from charged objects, such as human fingers or tools.
With the help of 3D printing techniques, researchers at Lawrence Livermore National Laboratory (LLNL) are “packaging” electronics with printable elastomeric silicone foams to provide both mechanical and electrical protection of sensitive components. Without suitable protection, substantial equipment and component failures may occur, leading to increased costs and potential workplace injuries. The team’s research is featured in ACS Applied Materials & Interfaces.
3D printing is a rapidly growing manufacturing method that enables the production of cellular foams with customizable pore architectures to achieve compressive mechanical properties that can be tailored to minimize permanent deformation by evenly distributing stress throughout the printed architecture.

An AI Chemist Made A Catalyst to Make Oxygen On Mars Using Local Materials
Posted by Dan Breeden in categories: chemistry, humor, information science, robotics/AI, space travel
Breaking oxygen out of a water molecule is a relatively simple process, at least chemically. Even so, it does require components, one of the most important of which is a catalyst. Catalysts enable reactions and are linearly scalable, so if you want more reactions quickly, you need a bigger catalyst. In space exploration, bigger means heavier, which translates into more expensive. So, when humanity is looking for a catalyst to split water into oxygen and hydrogen on Mars, creating one from local Martian materials would be worthwhile. That is precisely what a team from Hefei, China, did by using what they called an “AI Chemist.”
Unfortunately, the name “AIChemist” didn’t stick, though that joke might vary depending on the font you read it in. Whatever its name, the team’s work was some serious science. It specifically applied machine learning algorithms that have become all the rage lately to selecting an effective catalyst for an “oxygen evolution reaction” by utilizing materials native to Mars.
