China Shatters “Spooky Action at a Distance” Record, Preps for Quantum Internet

 

 

Results from the Micius satellite test quantum entanglement, pointing the way toward hack-proof global communications—and a new space race.

 

 

In a landmark study, a team of Chinese scientists using an experimental satellite has tested quantum entanglement over unprecedented distances, beaming entangled pairs of photons to three ground stations across China—each separated by more than 1,200 kilometres. The test verifies a mysterious and long-held tenet of quantum theory and firmly establishes China as the front-runner in a burgeoning “quantum space race” to create a secure, quantum-based global communications network—that is, a potentially unhackable “quantum internet” that would be of immense geopolitical importance. The findings were published Thursday in Science.

What does DNA sound like? Using music to unlock the secrets of genetic code

 

I’ve been studying molecular biology for many years. I also have a keen interest in music, having played with Sydney pop band the Hummingbirds. Usually, there is little overlap between these two pursuits, but I recently became aware of people using DNA sequences to create music.

This is called sonification. The people doing this usually treat DNA sequences as random patterns to create nice-sounding music. But what if we used musical notes to find out something useful about DNA sequences, like where mutations occur?

So I put on my coding hat and devised a tool that converts a DNA sequence into an audio stream. The results were recently published in the journal BMC Bioinformatics.

DNA Replication Has Been Filmed For The First Time, And It’s Not What We Expected

“It undermines a great deal of what’s in the textbooks.”

Here’s proof of how far we’ve come in science – in a world-first, researchers have recorded up-close footage of a single DNA molecule replicating itself, and it’s raising questions about how we assumed the process played out.

The real-time footage has revealed that this fundamental part of life incorporates an unexpected amount of ‘randomness’, and it could force a major rethink into how genetic replication occurs without mutations.

A New Test Could Detect Cancer Years Before Symptoms Show

IN BRIEF

A new non-invasive cancer test was able to detect cancer DNA in about 90 percent of blood samples, according to a recent study. This technique could help discover cancer years before actual symptoms appear.

SIMPLE AND NON-INVASIVE

Cancer research is one of the busiest fields in medical technology, and understandably so, as cancer remains one of the leading causes of death worldwide. While there are existing treatments available for cancer, these usually cause a terrible amount of strain on the body and aren’t always effective. But what if much of that could be avoided by early detection using a simple, non-invasive test? Researchers from the Memorial Sloan Kettering Cancer Center and genomics company Grail are close to developing such a procedure.

Einstein’s ‘Impossible’ Experiment Finally Performed

“Nunca digan que nunca sería posible “… “incensario pesimismo “….

A Hubble Space Telescope picture shows what’s known as an Einstein ring, when one galaxy bends and magnifies the light from a more distant one, as predicted by Einstein’s general theory of relativity. Astronomers have now used Hubble to see light from one star being bent by another in an experiment the famed physicist himself thought would be impossible to perform.
