How to see the invisible: Using the dark matter distribution to test our cosmological model      (via sciencedaily.com)     Original source 

Astrophysicists have measured a value for the 'clumpiness' of the universe's dark matter (known to cosmologists as 'S8') of 0.776, which does not align with the value derived from the Cosmic Microwave Background, which dates back to the universe's origins. This has intriguing implications for the standard cosmological model.

Technology advance paves way to more realistic 3D holograms for virtual reality and more      (via sciencedaily.com)     Original source 

Researchers have developed a new way to create dynamic ultrahigh-density 3D holographic projections. They now describe their new approach, called three-dimensional scattering-assisted dynamic holography (3D-SDH). They show that it can achieve a depth resolution more than three orders of magnitude greater than state-of-the-art methods for multiplane holographic projection.

Hubble sees possible runaway black hole creating a trail of stars      (via sciencedaily.com)     Original source 

There's an invisible monster on the loose, barreling through intergalactic space so fast that if it were in our solar system, it could travel from Earth to the Moon in 14 minutes. This supermassive black hole, weighing as much as 20 million Suns, has left behind a never-before-seen 200,000-light-year-long 'contrail' of newborn stars, twice the diameter of our Milky Way galaxy. It's likely the result of a rare, bizarre game of galactic billiards among three massive black holes.

Hubble unexpectedly finds double quasar in distant universe      (via sciencedaily.com)     Original source 

The early universe was a rambunctious place where galaxies often bumped into each other and even merged together. Using NASA's Hubble Space Telescope and other space and ground-based observatories, astronomers investigating these developments have made an unexpected and rare discovery: a pair of gravitationally bound quasars, both blazing away inside two merging galaxies. They existed when the universe was just 3 billion years old.

Robots predict human intention for faster builds      (via sciencedaily.com)     Original source 

Humans have a way of understandings others' goals, desires and beliefs, a crucial skill that allows us to anticipate people's actions. Taking bread out of the toaster? You'll need a plate. Sweeping up leaves? I'll grab the green trash can. This skill, often referred to as 'theory of mind,' comes easily to us as humans, but is still challenging for robots. But, if robots are to become truly collaborative helpers in manufacturing and in everyday life, they need to learn the same abilities. Computer science researchers aim to teach robots how to predict human preferences in assembly tasks, so they can one day help out on everything from building a satellite to setting a table.

Students use machine learning in lesson designed to reveal issues, promise of A.I.      (via sciencedaily.com)     Original source 

In a new study, researchers had 28 high school students create their own machine-learning artificial intelligence (AI) models for analyzing data. The goals of the project were to help students explore the challenges, limitations and promise of AI, and to ensure a future workforce is prepared to make use of AI tools.

Absolute zero in the quantum computer      (via sciencedaily.com)     Original source 

Absolute zero cannot be reached -- unless you have an infinite amount of energy or an infinite amount of time. Scientists in Vienna (Austria) studying the connection between thermodynamics and quantum physics have now found out that there is a third option: Infinite complexity. It turns out that reaching absolute zero is in a way equivalent to perfectly erasing information in a quantum computer, for which an infinetly complex quantum computer would be required.

Smart watches could predict higher risk of heart failure      (via sciencedaily.com)     Original source 

A study looked at data from 83,000 people who had undergone a 15-second electrocardiogram (ECG) comparable to the kind carried out using smart watches and phone devices. The researchers identified ECG recordings containing extra heart beats which are usually benign but, if they occur frequently, are linked to conditions such as heart failure and arrhythmia (irregular heartbeats). They found that people with an extra beat in this short recording (one in 25 of the total) had a twofold risk of developing heart failure or an irregular heart rhythm (atrial fibrillation) over the next 10 years.

AI algorithm unblurs the cosmos      (via sciencedaily.com) 

Researchers adapted a well-known computer-vision algorithm used for sharpening photos and, for the first time, applied it to astronomical images from ground-based telescopes. While astrophysicists already use technologies to remove blur, the adapted AI-driven algorithm works faster and produces more realistic images than current technologies. The resulting images are blur-free and truer to life.

'Taffy galaxies' collide, leave behind bridge of star-forming material      (via sciencedaily.com)     Original source 

The Gemini North telescope, one half of the International Gemini Observatory, operated by NSF's NOIRLab, captured a dazzling image of UGC 12914 and UGC 12915, which are nicknamed the Taffy Galaxies. Their twisted shape is the result of a head-on collision that occurred about 25 million years prior to their appearance in the image. A bridge of highly turbulent gas devoid of significant star formation spans the gap between the two galaxies.
