This plant chemical takes away soreness, but it turns out it also makes injured and bruised muscles heal faster.

Andrew Sinclair does not have anything to lose. He takes a number of drugs including the anti-diabetic medication metformin, given to him by his son David, the renowned Australian biologist and professor of genetics at Harvard Medical School, to combat the ill-effects of ageing.

David Sinclair says his father remains in good health, travelling, socialising and exercising with the energy of a man far younger than his 80 years.

David Sinclair will discuss why ageing should be classified as a disease at the Festival of Dangerous Ideas.

Recent findings of new Higgs modes in unconventional superconductors require a classification and characterization of the modes allowed by nontrivial gap symmetry. Here we develop a theory for a tailored nonequilibrium quantum quench to excite all possible oscillation symmetries of a superconducting condensate. We show that both a finite momentum transfer and quench symmetry allow for an identification of the resulting Higgs oscillations. These serve as a fingerprint for the ground state gap symmetry. We provide a classification scheme of these oscillations and the quench symmetry based on group theory for the underlying lattice point group. For characterization, analytic calculations as well as full scale numeric simulations of the transient optical response resulting from an excitation by a realistic laser pulse are performed. Our classification of Higgs oscillations allows us to distinguish between different symmetries of the superconducting condensate.

At a time when Beijing and Washington should be cooperating, both sides are locked in a strategic competition.

Dinorah Delfin has unleashed another exceptional edition of Immortalist Magazine. One of the best aspects is the dueling articles on the future states of Artificial General Intelligence (AGI).

Daniel Faggella constructs another dismal, dreary, depressing, destruction of hope for a benevolent artificial general intelligence. Emphasis on depressing. He has a wonderful way of creating a series of logical roadblocks to any optimism that there is a future with a compassionate artificial general intelligence. But he seems to be arguing against a contention that probably nobody believes in. He is arguing that there is no certainty that an artificial general intelligence will be benevolent. Most thinking humanoids are going to agree with that perspective. As he points out forcefully in his concluding and strongest rebuttal: no one knows what the future holds.

But no one is looking for absolute certainty in the far future. Transhumanists in general are looking for a path forward to an existence full of superhappiness, superintelligence and superlongevity.

How did Viruses evolve?

The evolutionary history of viruses remains unclear. Some researchers hypothesize that viruses evolved from mobile genetic elements that gained the ability to move between cells. Other researchers postulate that viruses evolved from more complex organisms that lost the ability to replicate independently. Still others hypothesize that DNA viruses gave rise to the eukaryotic nucleus or that viruses predate all cellular life-forms. Reasonable arguments can be made for all of these hypotheses. It may be that viruses arose multiple times, via each of these mechanisms. It may be that viruses arose from a mechanism yet to be described. Continuing studies of viruses and their hosts may provide us with clearer answers.

Percentage of patients with PCR-positive nasopharyngeal samples from inclusion to day6 post-inclusion in COVID-19 patients treated with hydroxychloroquine only, in COVID-19 patients treated with hydroxychloroquine and azithomycin combination, and in COVID-19 control patients.

Possible treatments for coronavirus:

Remdesivir by the firm Gilead was developed to fight other viruses including Ebola (where it was shown to be ineffective) and it hasn’t yet been approved for treating anything. Still, it has shown early promise in treating some coronavirus patients in China, according to doctors, and manufacturer Gilead is moving ahead with final stage clinical trials in Asia. It has also been used to treat at least one US patient so far.

NIH’s Anthony Fauci, one of the top government scientists overseeing the coronavirus response, has said it could be available in the next “several months.”

A team led by Prof. Guo Guangcan from University of Science and Technology of China (USTC) of the Chinese Academy of Sciences (CAS) and collaborators first realized distribution of high-dimensional orbital angular momentum entanglement over a 1 km few-mode fiber. The result is published in Optica.

Increasing the channel capacity and tolerance to noise in quantum communications is a strong practical motivation for encoding quantum information in multilevel systems, qudits as opposed to qubits. From a foundational perspective, entanglement in higher dimensions exhibits more complex structures and stronger non-classical correlations. High-dimensional entanglement has demonstrated its potential for increasing channel capacity and resistance to noise in quantum information processing. Despite these benefits, the distribution of high-dimensional entanglement is relatively new and remains challenging.

The orbital angular momentum of photon is a high dimensional system which has been paid much attention to in recent years. However, orbital angular momentum entanglement is susceptible to atmospheric turbulence or mode crosstalk and mode dispersion in optical fibers. It can only transmit a few meters, and is limited to two-dimensional entanglement distribution.
