Researchers alter mouse gut microbiomes
Posted by Xavier Rosseel in categories: biotech/medical, food, health, sustainability
Humans choose food based on the way it looks, smells, and tastes. But the microbes in our guts use a different classification system — one that is based on the molecular components that make up different fibers. In a study published September 19 in the journal Cell, investigators found particular components of dietary fiber that encourage growth and metabolic action of beneficial microbes in the mouse gut.
The research aims to develop ways to identify compounds that can enhance the representation of health-promoting members of the gut microbial community. The goal is to identify sustainable, affordable dietary fiber sources for incorporation into next-generation, more nutritious food products.
“Fiber is understood to be beneficial. But fiber is actually a very complicated mixture of many different components,” says senior author Jeffrey Gordon, a microbiologist at the Washington University School of Medicine in St. Louis. “Moreover, fibers from different plant sources that are processed in different ways during food manufacturing have different constituents. Unfortunately, we lack detailed knowledge of these differences and their biological significance. We do know that modern Western diets have low levels of fiber; this lack of fiber has been linked to loss of important members of the gut community and deleterious health effects.”

Richard Dawkins’ New Book, “Outgrowing God,” Brings Atheism to Younger Readers
Posted by Steve Nichols in category: futurism
Just to put this out there: There’s no shortage of Christian apologists who have written books tailored to a younger audience, and the Bible itself has all kinds of children’s editions. But when Dawkins’ book comes out, you can expect Christian writers to accuse Dawkins of trying to indoctrinate children into godlessness. Even though he’s doing exactly what they do, except from a different perspective. The difference is he actually has evidence on his side.
The book will be released this October.

New study links this common skin condition with an increased risk in heart disease
Posted by Genevieve Klien in categories: biotech/medical, genetics
Over 3 million new cases of dermatitis appear in the US per year. Although dermatitis is broadly defined by the sensitivity of the skin, the condition is actually further segmented by a group of diseases. By far the most popular of these is atopic dermatitis, alternatively and perhaps more popularly known as eczema, affecting about 30% of the population. Genetics and environmental factors are the most conclusive predictors but no cause has ever been explicitly determined. The pathology is able to be determined physically, as inflamed skin grows craked and hardens.
Though a new report published in the Journal of the American Academy of Dermatology presents some internal risk increases for sufferers to consider. The Danish researchers set out to examine the association between hospital-diagnosed atopic dermatitis and atrial fibrillation, writing in the report, “Atopic dermatitis is characterized by chronic inflammation, which is a risk factor for atrial fibrillation. P atients with hospital-diagnosed atopic dermatitis have a 20% increased long-term risk of atrial fibrillation, but the absolute risk remains low.”

The green revolution is necessary but not enough!
Posted by Adriano Autino in categories: space, sustainability
It is not a matter of “saving the planet”, but saving civilization and its development.
The only sustainable development is the one that aims at space, using the immense resources of the Solar System.

ATTUALITÀ DELLA MOZIONE FINALE DEL 2NDO CONGRESSO NAZIONALE DI SPACE RENAISSANCE ITALIA
La rivoluzione verde è necessaria ma non sufficiente! Non si tratta di “salvare il pianeta”, ma di salvare la civiltà ed il suo sviluppo. L’unico sviluppo sostenibile è quello che punta allo spazio, ad utilizzare le immense risorse del Sistema Solare.
All’agenda dei 17 obiettivi 2030 per lo sviluppo sostenibile dell’ONU deve essere aggiunto il 18mo obiettivo:

Are We Alone? ‘Ad Astra’ Star Brad Pitt Talks Aliens, Science Fiction and More
Posted by Derick Lee in categories: alien life, entertainment
When starting to create the movie, Gray said “Ad Astra” would be a “science feature fact” film and that he would endeavour to make it the most realistic space movie yet created. He admitted he had to adjust that vision as production continued. “A lot of times when you start working on a project, you start to say unbelieveably dumb things,” he joked.
Brad Pitt says his new space movie “Ad Astra” won’t have a clear position on whether humanity is alone in the universe.

AgeX Therapeutics Publishes Theoretical Basis of Human Cell Age-Reversal in the Journal Regenerative Medicine
Posted by Montie Adkins in categories: biotech/medical, business, life extension
A unified theory of ageing, there is a vid and a paper linked within.
ALAMEDA, Calif.—( BUSINESS WIRE )—AgeX Therapeutics, Inc. (“AgeX”; NYSE American: AGE), a biotechnology company focused on therapeutics for human aging and regeneration, announced today that founder and CEO Michael D. West, Ph.D., and colleagues have authored a paper in the peer-reviewed scientific journal Regenerative Medicine on the theoretical foundation of the Company’s induced Tissue Regeneration (iTRTM) technology. The paper presents the work of the company’s scientists in describing a unified theory of aging and regeneration that could pave the way for the development of new therapies for a variety of age-related degenerative diseases and conditions.
“The longevity sector is advancing at an accelerating pace, but for the most part, without a consensus on the fundamental root causes of aging,” commented Dr. West. “We believe that it is now possible to collate the diverse observations about aging into a unified model. In the paper titled, ‘Toward a Unified Theory of Aging and Regeneration’ we outline such a theory that underlies the technological underpinnings of the company’s induced tissue regeneration (iTR) program.”

Bridge between quantum mechanics and general relativity still possible
Posted by Saúl Morales Rodriguéz in categories: particle physics, quantum physics, space
Quantum mechanics and the general theory of relativity form the bedrock of the current understanding of physics—yet the two theories don’t seem to work together. Physical phenomena rely on relationship of motion between the observed and the observer. Certain rules hold true across types of observed objects and those observing, but those rules tend to break down at the quantum level, where subatomic particles behave in strange ways.
An international team of researchers developed a unified framework that would account for this apparent break down between classical and quantum physics, and they put it to the test using a quantum satellite called Micius. They published their results ruling out one version of their theory on Sept 19th in Science.
Micius is part of a Chinese research project called Quantum Experiments at Space Scale (QUESS), in which researchers can examine the relationship with quantum and classical physics using light experiments. In this study, the researchers used the satellite to produce and measure two entangled particles.
