By building the most general framework for the n-particle Hardy’s paradox and Hardy’s inequality, the results of the new paper provide a stronger Hardy’s paradox, and can also detect more quantum entangled states. As the success probability for the three-qubit generalized Hardy’s paradox reaches 0.25, the researchers are very hopeful that it will be observed in future experiments.

Researcher Dr. Dena Dubal, from the University of California San Francisco, is considering a new approach to combat neurodegenerative diseases, such as Alzheimer’s disease and dementia, using a protein known as klotho.

Aging is the foundation of age-related diseases

Instead of trying to understand each of these diseases and the complex mechanisms unique to both, she considered what all these conditions have in common; the answer, of course, is aging.

SAN JUAN, P.R. — They call what they are building Puertopia. But then someone told them, apparently in all seriousness, that it translates to “eternal boy playground” in Latin. So they are changing the name: They will call it Sol.

Dozens of entrepreneurs, made newly wealthy by blockchain and cryptocurrencies, are heading en masse to Puerto Rico this winter. They are selling their homes and cars in California and establishing residency on the Caribbean island in hopes of avoiding what they see as onerous state and federal taxes on their growing fortunes, some of which now reach into the billions of dollars.

And these men — because they are almost exclusively men — have a plan for what to do with the wealth: They want to build a crypto utopia, a new city where the money is virtual and the contracts are all public, to show the rest of the world what a crypto future could look like. Blockchain, a digital ledger that forms the basis of virtual currencies, has the potential to reinvent society — and the Puertopians want to prove it.

Under-the-skin chip (credit: EPFL)

A tiny (one-centimeter-square) biosensor chip developed at EPFL is designed to be implanted under your skin to continuously monitor concentrations of pH, temperature, and metabolism-related molecules like glucose, lactate and cholesterol, as well as some drugs.

The chip would replace blood work, which may take hours — or even days — for analysis and is a limited snapshot of conditions at the moment the blood is drawn.

If the goose that laid the golden egg had a real-life counterpart, it would be C. metallidurans. This hardy little bacterium consumes toxic metals and excretes tiny gold nuggets, but how and why it does so has never been fully understood. Now, German and Australian researchers have peered inside the microorganism and figured out that mechanism.

C. metallidurans has carved out a nice little niche for itself, usually living in soils full of heavy metals, which are toxic to most other microorganisms. But this bacteria has evolved a defense mechanism to help it not only survive but thrive under those conditions, and its ability to turn toxic compounds into gold is well known enough to once earn it a place in an alchemy art installation.

“Apart from the toxic heavy metals, living conditions in these soils are not bad,” says Dietrich H. Nies, an author on the new study. “There is enough hydrogen to conserve energy and nearly no competition. If an organism chooses to survive here, it has to find a way to protect itself from these toxic substances.”
