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.

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 fine structure constant.

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.

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.

Researcher says virus enters ‘defence line’ and causes circulation problems, which can lead to multiple organ failure.

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 building blocks for a large-scale implementation of quantum electrodynamics in ultracold atoms,” 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 building 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.

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.

When black holes swallow down massive amounts of matter from the space around them, they’re not exactly subtle about it. They belch out tremendous flares of X-rays, generated by the material heating to intense temperatures as it’s sucked towards the black hole, so bright we can detect them from Earth.

This is normal black hole behaviour. What isn’t normal is for those X-ray flares to spew forth with clockwork regularity, a puzzling behaviour reported last year from a supermassive black hole at the centre of a galaxy 250 million light-years away. Every nine hours, boom — X-ray flare.

After careful study, astronomer Andrew King of the University of Leicester in the UK believes he has identified the cause — a dead star that’s endured its brush with a black hole, trapped on a nine-hour, elliptical orbit around it. Every close pass, or periastron, the black hole slurps up more of the star’s material.
