NASA’s exoplanet hunter TESS spots a record-breaking 3-star system

Posted by in categories: robotics/AI, space

The team spotted the record-breaking triple star system because of strobing starlight caused by the stars crossing in front of each other, as seen from our position on Earth.

The team turned to machine learning to analyze vast amounts of data from TESS to spot a pattern indicating these eclipses. They then called upon the aid of citizen scientists to further filter this data to spot interesting signals.

“We’re mainly looking for signatures of compact multi-star systems, unusual pulsating stars in binary systems, and weird objects,” Rappaport said. “It’s exciting to identify a system like this because they’re rarely found, but they may be more common than current tallies suggest.”

A smooth exit from eternal inflation?

Posted by in categories: cosmology, quantum physics

I think Stephen hawking was right about the Einstein physics of our universe but at the quantum mechanical realm it breaks all the rules with infinite energy.


The usual theory of inflation breaks down in eternal inflation. We derive a dual description of eternal inflation in terms of a deformed Euclidean CFT located at the threshold of eternal inflation. The partition function gives the amplitude of different geometries of the threshold surface in the no-boundary state. Its local and global behavior in dual toy models shows that the amplitude is low for surfaces which are not nearly conformal to the round three-sphere and essentially zero for surfaces with negative curvature. Based on this we conjecture that the exit from eternal inflation does not produce an infinite fractal-like multiverse, but is finite and reasonably smooth.

Toyota unveils its secret and shocks the world: This engine is both combustion and zero-emission

Posted by in categories: energy, sustainability, transportation

In a surprise revelation, Toyota has sent shockwaves throughout the automotive world with an all-new engine that melds combustion technology with the potential for zero emissions. This stealth development may transform our thinking about green energy and the future of transportation. For two decades, the world has been struggling over what the road to sustainable transport would look like, and to date, EVs have proven a front-runner. However, Toyota’s latest development puts a monkey wrench into that thinking by suggesting that a hydrogen-powered combustion engine may be what carries us into the future.

While Toyota is no stranger to innovation—it gave the world its first mass-produced hybrid, the Prius, back in 1997—it has traditionally taken a more cautious approach toward anything resembling an electric vehicle. Less conservatively speaking, the hydrogen-powered combustion engine signifies a quantum leap. This latest motor technology is based on a variant of the same 1.6-liter turbocharged three-cylinder used in its GR Corolla and GR Yaris. Instead, it relies on hydrogen, not traditional gasoline, to run the engine, making it cleaner than conventional combustion engines.

This innovative engine could also hold the key to one of the most significant challenges for the car-making industry: balancing high performance with sustainability. While electric cars take away that visceral experience from driving enthusiasts, Toyota’s hydrogen engine ensures a gasoline-powered car’s rumble, response, and mechanical integrity. The company tested it thoroughly through the grueling conditions of motorsports, including endurance events such as the Fuji 24 Hours.

Research provides new insights into role of mechanical forces in gene expression

Posted by in category: biotech/medical

The genome inside each of our cells is modeled by tension and torsion—due in part to the activity of proteins that compact, loop, wrap and untwist DNA—but scientists know little about how those forces affect the transcription of genes.

New Molecule Mimics Exercise and Fasting Effects

Posted by in categories: health, neuroscience

Summary: Researchers have developed a molecule called LaKe that mimics the metabolic effects of strenuous exercise and fasting. This molecule increases lactate and ketone levels in the body, providing similar benefits to running 10 kilometers on an empty stomach, without physical exertion or dietary changes.

Currently being tested in human trials, LaKe shows promise for helping people with limited physical ability maintain health, and may also aid in treating brain conditions like Parkinson’s and dementia. The discovery offers a potential new path for those unable to follow strict exercise or fasting routines.
