Could this copycat black hole be a new type of star?      (via sciencedaily.com)     Original source 

It looks like a black hole and bends light like a black hole, but it could actually be a new type of star. Though the mysterious object is a hypothetical mathematical construction, new simulations by Johns Hopkins researchers suggest there could be other celestial bodies in space hiding from even the best telescopes on Earth.

Now you can be comfortable in your e-skin      (via sciencedaily.com)     Original source 

Researchers have designed a cellulose nanofiber paper (nanopaper) that can be used as a substrate for on-skin electronics. The porous structure of the nanopaper means that it can conform and adhere to the skin well enough for effective signal transfer and allows moisture to pass through for breathability and comfort. It is hoped that the nanopaper can soon be used to acquire electrophysiological data, such as ECGs in the clinic.

Teasing strange matter from the ordinary      (via sciencedaily.com)     Original source 

In a unique analysis of experimental data, nuclear physicists have made observations of how lambda particles, so-called 'strange matter,' are produced by a specific process called semi-inclusive deep inelastic scattering (SIDIS). What's more, these data hint that the building blocks of protons, quarks and gluons, are capable of marching through the atomic nucleus in pairs called diquarks, at least part of the time.

Team designs four-legged robotic system that can walk a balance beam      (via sciencedaily.com)     Original source 

Researchers have designed a system that makes an off-the-shelf quadruped robot nimble enough to walk a narrow balance beam -- a feat that is likely the first of its kind.

Coastal species persist on high seas on floating plastic debris      (via sciencedaily.com)     Original source 

The high seas have been colonized by a surprising number of coastal marine invertebrate species, which can now survive and reproduce in the open ocean, contributing strongly to the floating community composition. Researchers found coastal species, representing diverse taxonomic groups and life history traits, in the eastern North Pacific Subtropical Gyre on over 70 percent of the plastic debris they examined. Further, the debris carried more coastal species than open ocean species.

New details of Tully monster revealed      (via sciencedaily.com)     Original source 

For more than half a century, the Tully monster (Tullimonstrum gregarium), an enigmatic animal that lived about 300 million years ago, has confounded paleontologists, with its strange anatomy making it difficult to classify. Recently, a group of researchers proposed a hypothesis that Tullimonstrum was a vertebrate similar to cyclostomes (jawless fish like lamprey and hagfish). If it was, then the Tully monster would potentially fill a gap in the evolutionary history of early vertebrates. Studies so far have both supported and rejected this hypothesis. Now, using 3D imaging technology, a team in Japan believes it has found the answer after uncovering detailed characteristics of the Tully monster which strongly suggest that it was not a vertebrate. However, its exact classification and what type of invertebrate it was is still to be decided.

Can you describe a sensation without feeling it first?      (via sciencedaily.com)     Original source 

Research with a unique, perhaps one-of-a-kind individual, shows that you can comprehend and use tactile language and metaphors without relying on previous sensory experiences. These findings challenge notions of embodied cognition that insist that language comprehension and abstract thought require direct memory of such sensations.

Ancient DNA reveals the multiethnic structure of Mongolia's first nomadic empire      (via sciencedaily.com)     Original source 

The Xiongnu, contemporaries of Rome and Egypt, built their nomadic empire on the Mongolian steppe 2,000 years ago, emerging as Imperial China's greatest rival and even inspiring the construction of China's Great Wall. In a new study, researchers find that the Xiongnu were a multiethnic empire, with high genetic diversity found across the empire and even within individual extended elite families. At the fringes of the empire, women held the highest positions of power, and the highest genetic diversity was found among low-status male servants, giving clues to the process of empire building that gave rise to Asia's first nomadic imperial power.

Playing hide and seek with planets      (via sciencedaily.com)     Original source 

An international team of astronomers announced the first exoplanet discovered through a combined approach of direct imaging and precision measurements of a star's motion on the sky. This new method promises to improve the efficiency of exoplanet searches, paving the way for the discovery of an Earth twin.

New exoplanet discovered      (via sciencedaily.com)     Original source 

Astronomers report the first exoplanet jointly discovered through direct imaging and precision astrometry, a new indirect method that identifies a planet by measuring the position of the star it orbits. Data from the Subaru Telescope in Hawai`i and space telescopes from the European Space Agency (ESA) were integral to the team's discovery.

A sharper look at the M87 black hole      (via sciencedaily.com)     Original source 

The iconic image of the supermassive black hole at the center of M87 has gotten its first official makeover based on a new machine learning technique called PRIMO. The team used the data achieved the full resolution of the array.

M87 in 3D: New view of galaxy helps pin down mass of the black hole at its core      (via sciencedaily.com)     Original source 

From Earth, giant elliptical galaxies resemble highly symmetric blobs, but what's their real 3D structure? Astronomers have assembled one of the first 3D views of a giant elliptical galaxy, M87, whose central supermassive black hole has already been imaged by the Event Horizon Telescope. M87 turns out to be triaxial, like a potato. The revised view provides a more precise measure of the mass of the central black hole: 5.37 billion solar masses.

James Webb Space Telescope images challenge theories of how universe evolved      (via sciencedaily.com)     Original source 

Astronomers find that six of the earliest and most massive galaxy candidates observed by the James Webb Space Telescope so far appear to have converted nearly 100% of their available gas into stars, a finding at odds with the reigning model of cosmology.

Apes may have evolved upright stature for leaves, not fruit, in open woodland habitats      (via sciencedaily.com)     Original source 

Anthropologists have long thought that our ape ancestors evolved an upright torso in order to pick fruit in forests, but new research from the University of Michigan suggests a life in open woodlands and a diet that included leaves drove apes' upright stature.

Researchers discover tiny galaxy with big star power using James Webb telescope      (via sciencedaily.com)     Original source 

Using new observations from the James Webb Space Telescope, astronomers looked more than 13 billion years into the past to discover a unique, minuscule galaxy that could help astronomers learn more about galaxies that were present shortly after the Big Bang.

Oldest bat skeletons ever found described from Wyoming fossils      (via sciencedaily.com)     Original source 

Scientists have described a new species of bat based on the oldest bat skeletons ever recovered. The study on the extinct bat, which lived in Wyoming about 52 million years ago, supports the idea that bats diversified rapidly on multiple continents during this time.
