In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: the atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.$$!ad_code_content_spilt_video_ad!$$” Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the fascinating experiment. In the laboratory, her team observed how macrodroplets formed in a quantum gas.

When you see a photo of a dog bounding across the lawn, it’s pretty easy for us humans to imagine how the following moments played out. Well, scientists at MIT have just trained machines to do the same thing, with artificial intelligence software that can take a single image and use it to to create a short video of the seconds that followed. The technology is still bare-bones, but could one day make for smarter self-driving cars that are better prepared for the unexpected, among other applications.

The software uses a deep-learning algorithm that was trained on two million unlabeled videos amounting to a year’s worth of screen time. It actually consists of two separate neural networks that compete with one another. The first has been taught to separate the foreground and the background and to identify the object in the image, which allows the model to then determine what is moving and what isn’t.

The diamonds are made from radioactive graphite and can generate a small electric current for thousands of years.

New paper describes for first time how scientists can test controversial idea that speed of light is not a constant.

Researchers have figured out why plasma fields rapidly snap and reconnect.

Since man first explored space, it has been a largely peaceful environment. But now US adversaries are deploying weapons beyond Earth’s atmosphere, leading the US military to prepare for the frightening prospect of war in space.

“As humans go out there, there has always been conflict. Conflict in the Wild West as we move in the West … conflict twice in Europe for its horrible world wars,” Gen. John Hyten, head of US Strategic Command, told CNN. “So, every time humans actually physically move into that, there’s conflict, and in that case, we’ll have to be prepared for that.”

The field, now called low-energy nuclear reactions, may have legit results—or be stubborn junk science.

Wearable fitness devices could help you with your personal longevity strategy.

NEW YORK — Activity monitors could improve our health and extend our lives — if only we could be motivated to use them. Those are the conclusions of two new studies about the promise and perils of relying on fitness trackers to measure and guide how we move.

The monitors, which are expected to be a popular holiday gift again this year, can generally track our steps, speed, stance (sitting or not), distance, energy expenditure and heart rate. The absolute accuracy of these numbers, however, is somewhat suspect, with past studies finding errors in many of the monitors’ measurements. But the inaccuracies are usually consistent, the studies show, so the trackers can reliably indicate how our movements change from day to day.

THERE are multiple timelines playing out in parallel universes, according to a team of researchers.

The sensational claim was made by a team of physicists, who believe that the parallel universes can all affect one another.
