“Unexpected” Events have been Detected at the world’s most Sensitive Dark Matter Experiment.

Unusual behaviour could require new physics to be explained

Researchers do not claim to have found dark matter, but they say that there is an as yet unexplained and unexpected rate of events found in data from the experiment, and that they do not know the source.

The new breakthrough could be a sign of an entirely newly discovered kind of particle, or unpredicted behaviour that may require us to fundamentally change our understanding of physics.

The results come from the XENON collaboration, which brought together researchers from across the world who were attempting to detect dark matter. It did so using an experiment known as XENON1T, which was located deep underground in Italy.

Seeing evidence of dark matter would be one of the biggest possible breakthroughs in science...

Light-activated ‘CRISPR’ Triggers Precision Gene Editing and Super-fast DNA Repair

In a series of experiments using human cancer cell lines, scientists at Johns Hopkins Medicine say they have successfully used light as a trigger to make precise cuts in genomic material rapidly, using a molecular scalpel known as CRISPR, and observe how specialized cell proteins repair the exact spot where the gene was cut.

Results of the experiments, published June 11 in Science, not only reveal new details about the DNA repair process, but also are likely, the researchers say, to speed up and aid understanding of the DNA a...

Intel, Google, UC Berkeley AI team Trains Robot to do sutures

The next time you go to a hospital for surgery, the surgeon’s assistant may be a robot.

In a collaboration between Google Brain, Intel Corporation and the University of California, Berkeley, researchers have ‘trained’ robots to mimic surgical procedures through the use of instructional videos.

UC Berkeley professors have previously used YouTube videos as a guide for robots to learn various motions such as jumping or dancing, while Google has trained robots to understand depth and motion. The team applied that knowledge to their latest project, Motion2Vec, in which videos of actual surgical procedures are used for instruction...

Astronomers detect Regular Rhythm of Radio Waves, with origins unknown

CHIME, pictured here, consists of four large antennas, each about the size and shape of a snowboarding half-pipe, and is designed with no moving parts. Rather than swiveling to focus on different parts of the sky, CHIME stares fixedly at the entire sky, looking for fast radio burst sources across the universe.

Signal from 500 million light years away is the first periodic pattern of radio bursts detected. A team of astronomers, including researchers at MIT, has picked up on a curious, repeating rhythm of fast radio bursts emanating from an unknown source outside our galaxy, 500 million light years away.

Fast radio bursts, or FRBs, are short, intense flashes of radio waves that are thought to be the product of small, distant, extremely dense objects, though exac...
