A newly proposed table-top experiment might be able to demonstrate that gravity is quantized

Posted by in categories: particle physics, quantum physics

Tl;dr: Experimentalists are bringing increasingly massive systems into quantum states. They are now close to masses where they might be able to just measure what happens to the gravitational field.

Quantum effects of gravity are weak, so weak they are widely believed to not be measurable at all. Freeman Dyson indeed is fond of saying that a theory of quantum gravity is entirely unnecessary, arguing that we could never observe its effects anyway. Theorists of course disagree, and not just because they’re being paid to figure out the very theory Dyson deems unnecessary. Measurable or not, they search for a quantized version of gravity because the existing description of nature is not merely incomplete – it is far worse, it contains internal contradictions, meaning we know it is wrong.

Take the century-old double-slit experiment, the prime example for quantum behavior. A single electron that goes through the double-slit is able to interact with itself, as if it went through both slits at once. Its behavior is like that of a wave which overlaps with itself after passing an obstacle. And yet, when you measure the electron after it went through the slit it makes a dot on a screen, like a particle would. The wave-like behavior again shows up if one measures the distribution of many electrons that passed the slit. This and many other experiments demonstrate that the electron is neither a particle nor a wave – it is described by a wave-function from which we obtain a probability distribution, a formulation that is the core of quantum mechanics.

“When the Rosetta spacecraft deployed the Philae lander to land on a comet last November, the world held its breath. … Little surprise too that space is back on the design agenda as a primary source of inspiration. Visiting Design Miami/Basel in June, it was obvious that the “Philae effect” was having an impact much closer to home.”

What Protects Elephants From Cancer?

Posted by in categories: biotech/medical, life extension

Elephants are long-lived, and rather large. Given their size and longevity, scientists have pondered what protects them from cancer for a long time. Thanks to new research, we now know.

A mystery unlocked

Cancer is a big problem. A staggering 1 in 2 people born after 1960 in the UK are predicted to develop cancer at some point in their lifetime. We may be living longer, but the extra years are coming with a raised cancer risk. We may be getting better at treatment, but we’re still finding out exactly what causes it, and how we can prevent it from being a danger altogether.

Key to longevity? Blocking over 200 genes boosts lifespan

Posted by in categories: biotech/medical, genetics, health, life extension, nanotechnology

Aging is 100% genetic, the reason you go from infant to child to adult to old age.

We need to be scrutinizing Progeria, and the case of the girl who died at 20 and was stuck at the age of a toddler, for the key to the genes that will pause aging. While nanotechnology advances parallel with the cure for all diseases.


Once a bucket of genes linked to aging is removed, the lifespan of cells increases significantly, American scientists discovered during ten years of meticulous research, stressing that the results could be applied to humans.

Close cousins? Comparison between Earth and Kepler-452b and their host stars

Posted by in category: space

Scientists using data from NASA’s Kepler mission have confirmed the first near-Earth-size planet orbiting in the habitable zone of a sun-like star. The habitable zone is the region around a star where temperatures are just right for water to exist in its liquid form.

The artistic concept compares Earth (left) to the new planet, called Kepler-452b, which is about 60 percent larger. The illustration represents one possible appearance for Kepler-452b — scientists do not know whether the planet has oceans and continents like Earth.

Both planets orbit a G2-type star of about the same temperature; however, the star hosting Kepler-452b is 6 billion years old, 1.5 billion years older than our sun. As stars age, they become larger, hotter and brighter, as represented in the illustration. Kepler-452b’s star appears a bit larger and brighter.

[AMA] My name is Liz Parrish, CEO of BioViva, the first patient to be treated with gene therapy to reverse aging, ask me anything. • /r/Futurology

Posted by in categories: bioengineering, biotech/medical, education, genetics, health, life extension

Liz Parrish is the Founder and CEO of BioViva Sciences USA Inc. BioViva is committed to extending healthy lifespans using gene therapy. Liz is known as “the woman who wants to genetically engineer you,” she is a humanitarian, entrepreneur and innovator and a leading voice for genetic cures. As a strong proponent of progress and education for the advancement of gene therapy, she serves as a motivational speaker to the public at large for the life sciences. She is actively involved in international educational media outreach and sits on the board of the International Longevity Alliance (ILA). She is an affiliated member of the Complex Biological Systems Alliance (CBSA) whose mission is to further scientific understanding of biological complexity and the nature and origins of human disease. She is the founder of BioTrove Investments LLC and the BioTrove Podcasts which is committed to offering a meaningful way for people to learn about and fund research in regenerative medicine. She is also the Secretary of the American Longevity Alliance (ALA) a 501©(3) nonprofit trade association that brings together individuals, companies, and organizations who work in advancing the emerging field of cellular & regenerative medicine with the aim to get governments to consider aging a disease. I am not a medical doctor or scientist. I can not answer details of therapy. I would like to discuss my experience of creating BioViva, organizing the gene therapies, and then finally being able to administer it to the first human.
