The biggest of the three is predicted to be up to 30 metres wide.

Remarkable rules have been detected in the apparent chaos of disequilibrium processes. Different systems behave identically in many ways, if they belong to the same “universality class.” This means that experiments can be carried out with quantum systems that are easy to handle in order to obtain precise information about systems that cannot be directly studied in the experiment—such as the Big Bang.
Some phenomena are so complicated that it is impossible to precisely calculate them. This includes large quantum systems, which consist of many particles, particularly when they are not in an equilibrium state, but changing rapidly. Such examples include the wild particle inferno that occurs in particle accelerators when large atoms collide, or conditions just after the Big Bang, when particles rapidly expanded and then cooled.
At TU Wien and Heidelberg University, remarkable rules have been detected in the apparent chaos of disequilibrium processes. This indicates that such processes can be divided into universality classes. Systems belonging to the same class behave identically in many ways. This means that experiments can be carried out with quantum systems that are easy to handle in order to obtain precise information about other systems that cannot be directly studied in the experiment. These findings have since been published in the journal Nature.

This year, more candidates with degrees in science, medicine and engineering ran for Congress than ever before. Of the nearly two-dozen new candidates in this crop, at least seven won seats in the House of Representatives.
This year, scientists, doctors and engineers ran for office like never before. Here’s how they did.

We as human have to live with a lot of unfortunate realities, including the fact that a lot of the things we love end up being bad for us. We all know by now that if we binge on tasty treats too much we’ll end up eating ourselves into an early grave, but in recent years it’s become increasingly clear that coffee, a well known vice of millions and millions of people, is actually pretty good for you.
Recent studies have shown that being a regular coffee drinker can reduce your risk of all kinds of ailments, including heart attack and stroke. Now, a new research effort reveals that dark roast coffee is particularly good at warding off some nasty brain conditions, including Alzheimer’s and Parkinson’s disease.

Wormholes — yawning gateways that could theoretically connect distant points in space-time — are usually illustrated as gaping gravity wells linked by a narrow tunnel.
But their precise shape has been unknown.
Now, however, a physicist in Russia has devised a method to measure the shape of symmetric wormholes — even though they have not been proven to exist — based on the way the objects may affect light and gravity. [8 Ways You Can See Einstein’s Theory of Relativity in Real Life].

Researchers at Carnegie Mellon University have recently developed a new model that enables fast and accurate object detection in high-resolution 4K and 8K video footage using GPUs. Their attention pipeline method carries out a two-stage evaluation of every image or video frame under rough and refined resolution, limiting the total number of evaluations necessary.
In recent years, machine learning has attained remarkable results in computer vision tasks, including object detection. However, most object recognition models typically perform best on images with a relatively low resolution. As the resolution of recording devices is rapidly improving, there is a rising need for tools that can process high-resolution data.
“We were interested in finding and overcoming the limitations of current approaches,” Vít Růžička, one of the researchers who carried out the study told TechXplore. “While plenty of data sources record in high resolution, current state-of-the-art object detection models, such as YOLO, Faster RCNN, SSD, etc., work with images that have a relatively low resolution of approximately 608 × 608 px. Our main objective was to scale the object detection task to 4K-8K videos (up to 7680 × 4320 px) while maintaining high processing speed. We also wanted to understand if and by how much we can benefit from high resolution compared to using low-resolution images, in terms of accuracy of the models.”
