SpaceX ends launch hiatus with cargo Dragon mission

Posted by in categories: internet, satellites

WASHINGTON — SpaceX performed its first Falcon 9 launch in two months Aug. 29 sending a cargo Dragon spacecraft to the International Space Station.

The Falcon 9 lifted off from Launch Complex 39A at the Kennedy Space Center at 3:14 a.m. Eastern after a one-day delay because of weather. The Dragon spacecraft separated from the rocket’s upper stage about 12 minutes after liftoff and is scheduled to dock with the station at about 11 a.m. Eastern Aug. 30 for an approximately one-month stay.

The launch was the first for a Falcon 9 since the June 30 launch of the Transporter-2 rideshare mission, the longest pause since a three-month gap between launches from August to November 2019. One reason for the hiatus was a delay in Starlink launches to equip those satellites with laser inter-satellite links; the majority of the Falcon 9 launches this year have been Starlink missions.

Experimental Confirmation of the Fundamental Principle of Wave-Particle Duality

Posted by in categories: particle physics, quantum physics

Complementarity relation of wave-particle duality is analyzed quantitatively with entangled photons as path detectors.

The twenty-first century has undoubtedly been the era of quantum science. Quantum mechanics was born in the early twentieth century and has been used to develop unprecedented technologies which include quantum information, quantum communication, quantum metrology, quantum imaging, and quantum sensing. However, in quantum science, there are still unresolved and even inapprehensible issues like wave-particle duality and complementarity, superposition of wave functions, wave function collapse after quantum measurement, wave function entanglement of the composite wave function, etc.

To test the fundamental principle of wave-particle duality and complementarity quantitatively, a quantum composite system that can be controlled by experimental parameters is needed. So far, there have been several theoretical proposals after Neils Bohr introduced the concept of “complementarity” in 1,928 but only a few ideas have been tested experimentally, with them detecting interference patterns with low visibility. Thus, the concept of complementarity and wave-particle duality still remains elusive and has not been fully confirmed experimentally yet.

I’m A Longevity Expert & These Are My 5 Nonnegotiables To Live To 200

Posted by in category: life extension

It’s his personal mission to make it to 200.


Sergey Young has made it his personal mission to live to 200. Seriously: The longevity expert, founder of the Longevity Vision Fund, and author of The Science and Technology of Growing Young, has dedicated his entire career to helping at least 1 billion people live long, healthy lives—and make these technological advances affordable and accessible for all.

Through his work, he has identified what he calls lifestyle “longevity buckets” to increase your lifespan and healthspan (because who wants to live to 200 with a low quality of life?). “By implementing them, we can add 10 20 healthy and happy years to our life,” he says on this episode of the mindbodygreen podcast. “We can easily live 200 years.”

Physicists may have just detected a cloud of dark matter particles! It could also be primordial black holes, but either would be a major breakthrough.

Exploring Dubai’s Empty $13 Billion Man-Made Islands

Posted by in category: futurism

*BLACK FRIDAY DROP Out Now*: http://seek-discomfort.com/yes-theory.
This week only, with every purchase about $35, you’ll get a Free Seeker necklace.

The World Islands. A collection of 300 man-made islands built off the coast of Dubai to resemble an outline of the EARTH FROM THE SKY… Yet, after $13 billion was spent to complete them they’ve mostly been sitting there empty… I couldn’t believe this place actually existed.

The Science Behind NMN —A Stable, Reliable NAD+Activator and Anti-Aging Molecule

Posted by in categories: biotech/medical, genetics, life extension, neuroscience, science

Nad plus works for alzheimers.


In June of 2,018 the World Health Organization (WHO) released the 11th edition of its International Classification of Diseases, and for the first time added aging. The classification of aging as a disease paves the way for new research into novel therapeutics to delay or reverse age-related illnesses such as cancer, cardiovascular and metabolic disease, and neurodegeneration., Nutrient sensing systems have been an intense focus of investigation, including mTOR (the mammalian target of rapamycin) for regulating protein synthesis and cell growth; AMPK (activated protein kinase) for sensing low energy states; and sirtuins, a family of seven proteins critical to DNA expression and aging, which can only function in conjunction with NAD+ (nicotinamide adenine dinucleotide), a coenzyme present in all living cells.

Across the kingdom of life, an increase in intracellular levels of NAD+ triggers shifts that enhance survival, including boosting energy production and upregulating cellular repair. In fact, the slow, ineluctable process of aging has been described as a “cascade of robustness breakdown triggered by a decrease in systemic NAD+ biosynthesis and the resultant functional defects in susceptible organs and tissues.” Aging is marked by epigenetic shifts, genomic instability, altered nutrient sensing ability, telomere attrition, mitochondrial dysfunction, cellular senescence, stem cell exhaustion, and dysregulated intercellular communication.,

By middle age, our NAD+ levels have plummeted to half that of our youth. Numerous studies have demonstrated that boosting NAD+ levels increases insulin sensitivity, reverses mitochondrial dysfunction, and extends lifespan., NAD+ levels can be increased by activating enzymes that stimulate synthesis of NAD+, by inhibiting an enzyme (CD38) that degrades NAD+, and by supplementing with NAD precursors, including nicotinamide riboside(NR) and nicotinamide mononucleotide (NMN)., A conceptual framework called NAD World, formulated over the last decade by developmental biologist Shin-ichiro Imai, MD, PhD, of Washington University School of Medicine, posits NMN as a critical, systemic signaling molecule that maintains biological robustness of the communication network supporting NAD+..

Novel Nanophotonic Analog Processor Developed for High Performance Computing

Posted by in categories: computing, information science

Analog photonic solutions offer unique opportunities to address complex computational tasks with unprecedented performance in terms of energy dissipation and speeds, overcoming current limitations of modern computing architectures based on electron flows and digital approaches.

In a new study published on August 26 2021, in the journal Nature Communications Physics, researchers led by Volker Sorger, an associate professor of electrical and computer engineering at the George Washington University, reveal a new nanophotonic analog processor capable of solving partial differential equations. This nanophotonic processor can be integrated at chip-scale, processing arbitrary inputs at the speed of light.

The research team also included researchers at the University of California, Los Angeles, and City College of New York.

Scientists claim they discovered the “gate of consciousness”

Posted by in category: neuroscience

Because we can’t possibly absorb every single stimulus, our brain lets some of these signals filter through to our consciousness while others don’t.

But where specifically in the brain does that filtering take place? If somewhere in the brain exists the gateway to consciousness, which part of the brain functions as the gatekeeper?

Researchers at the University of Michigan Medical School set out to answer this question. Their study, published Tuesday in Cell Reports, suggests they’ve found the answer.
