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.

Scientists reveal how the brain responds to six different types of love

Posted by in category: neuroscience

The researchers also gathered behavioral data, asking participants how strongly they felt the emotions described in each story and how similar these feelings were across different objects of love. This helped the team link subjective emotional experiences to the observed brain activity.

“We use state-of-the-art technology to measure what happens in the brain when a person feels love,” Rinne told PsyPost. “We studied many different types of love and were able to show how different types of love activate the brain in different ways. Our results help explain why the word ‘love’ is used in so many different contexts. Our research also offers insights into why we feel stronger affection for those we are close to compared to strangers, even though the underlying brain processes of affection are the same for all types of interpersonal relationships.”

The study found that different types of love engage both shared and distinct regions of the brain. At a general level, all types of love activated areas associated with social cognition, including the medial prefrontal cortex, the temporoparietal junction, and the precuneus. These regions are involved in understanding others’ thoughts and emotions, a process known as theory of mind. This suggests that even when we experience love for non-human objects, like nature, our brain still engages these neural pathways.
