Applying quantum-impurity theory to quantum fluids of light

Posted by in categories: particle physics, quantum physics

A Monash-led study develops a new approach to directly observe correlated, many-body states in an exciton-polariton system that go beyond classical theories.

The study expands the use of quantum impurity theory, currently of significant interest to the cold-atom physics community, and will trigger future experiments demonstrating many-body quantum correlations of microcavity polaritons.

This AI wrote such emo lyrics that humans thought it was My Chemical Romance

Posted by in category: robotics/AI

I got my rig in the back of my Beemer. Professional when I graze, I’m professional when I argue. 40 glass, I’m laughing at that s***, I’ma be roaring at that s***

The experiment also revealed which genres are hardest for AI songwriters to master.

The respondents struggled to spot which pop and country lyrics were written by an AI. And its rock song was so emo that they thought it was written by My Chemical Romance or Nirvana.

New findings suggest laws of nature ‘downright weird,’ not as constant as previously thought

Posted by in categories: quantum physics, space

Not only does a universal constant seem annoyingly inconstant at the outer fringes of the cosmos, it occurs in only one direction, which is downright weird.

Those looking forward to a day when science’s Grand Unifying Theory of Everything could be worn on a t-shirt may have to wait a little longer as astrophysicists continue to find hints that one of the cosmological constants is not so constant after all.

In a paper published in Science Advances, scientists from UNSW Sydney reported that four new measurements of light emitted from a quasar 13 billion light years away reaffirm past studies that found tiny variations in the .

Why synthetic biology is about much more than resurrecting woolly mammoths

Posted by in categories: bioengineering, biotech/medical, genetics

Synthetic biology has been described as a kind of “genetic engineering on steroids”.


Synthetic biology …Simply mentioning this term — whether at a cocktail party or on a pop culture TV show — evokes a plethora of responses. These could range from puzzled looks to questions about the somewhat famous, though likely quixotic, quest to resurrect a woolly mammoth from remnants recovered in Siberia. Also, on the radar screen is synthetic biology as applied to the development of drugs and biological weapons. But flying below the radar — and, oddly, the sweet spot for investments by governments and private industry — is a less sexy focus on the industrial uses of synthetic biology. Such uses range from environmental clean-ups to new energy sources.

Restoring Telomerase Activity in Telomere Biology Diseases

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

Researchers have demonstrated that it is possible to restore telomerase activity in stem cells affected by telomere biology diseases, which prevent them from producing telomerase and repairing their telomeres.

Telomeres and telomerase

Each chromosome that stores our genetic information has a protective cap at each end known as a telomere, a specific DNA sequence that is repeated thousands of times. This sequence has two purposes: it protects the coding regions of the chromosome and prevents it from being damaged, and it acts as a clock that controls the number of replications a cell can make; this is known as the Hayflick limit.

Quantum electrodynamics experiment ‘major step toward’ large-scale implementation

Posted by in categories: particle physics, quantum physics

The fundamental laws of physics are based on symmetries that determine the interactions between charged particles, among other things. Using ultracold atoms, researchers at Heidelberg University have experimentally constructed the symmetries of quantum electrodynamics. They hope to gain new insights for implementing future quantum technologies that can simulate complex physical phenomena. The results of the study were published in the journal Science.

The theory of quantum electrodynamics deals with the electromagnetic interaction between electrons and light particles. It is based on so-called U symmetry, which, for instance, specifies the movement of particles. With their experiments, the Heidelberg physicists, under the direction of Junior Professor Dr. Fred Jendrzejewski, seek to advance the efficient investigation of this complex physical theory. They recently experimentally realized one elementary building block. “We see the results of our research as a major step toward a platform built from a chain of properly connected for a large-scale implementation of quantum in ,” explains Prof. Jendrzejewski, who directs an Emmy Noether group at Heidelberg University’s Kirchhoff Institute for Physics.

According to the researchers, one possible application would be developing large-scale quantum devices to simulate complex physical phenomena that cannot be studied with particle accelerators. The elementary block developed for this study could also benefit the investigation of problems in materials research, such as in strongly interacting systems that are difficult to calculate.

See a string of lights in the sky? It was probably SpaceX’s ‘Starlink’ satellites

Posted by in categories: economics, satellites

We’re getting many calls and emails from WGN viewers who say they spotted a strange string of lights crossing the night sky on Sunday.

No, it’s not planes flying in formation or a meteor shower. It’s actually a satellite string that’s part of SpaceX’s “Starlink” project. You can read more about it below.

While much of the world economy stands still, SpaceX is running full speed ahead.
