Astronomers discover 49 new galaxies in under three hours      (via sciencedaily.com)     Original source 

New work aimed to study the star-forming gas in a single radio galaxy. Although the team didn't find any star-forming gas in the galaxy they were studying, they instead discovered other galaxies while inspecting the data. In total, the gas of 49 galaxies was detected.

Wild bird gestures 'after you'      (via sciencedaily.com)     Original source 

A small-bird species, the Japanese tit (Parus minor), uses wing movements as a gesture to convey the message 'after you,' according to new research. When a mating pair arrives at their nest box with food, they will wait outside on perches. One will then often flutter its wings toward the other, apparently indicating for the latter to enter first. The researchers say that this discovery challenges the previous belief that gestural communication is prominent only in humans and great apes, significantly advancing our understanding of visual communication in birds.

If faces look like demons, you could have this extraordinary condition      (via sciencedaily.com)     Original source 

Imagine if every time you saw a face, it appeared distorted. Well, for those who have a very rare condition known as prosopometamorphopsia (PMO), which causes facial features to appear distorted, that is reality. A new study reports on a unique case of a patient with PMO. The research is the first to provide accurate and photorealistic visualizations of the facial distortions experienced by an individual with PMO.

James Webb Space Telescope captures the end of planet formation      (via sciencedaily.com)     Original source 

How much time do planets have to form from a swirling disk of gas and dust around a star? A new study gives scientists a better idea of how our own solar system came to be.

Signs of life would be detectable in single ice grain emitted from extraterrestrial moons      (via sciencedaily.com)     Original source 

Could life be found in frozen sea spray from moons orbiting Saturn or Jupiter? New research finds that life can be detected in a single ice grain containing one bacterial cell or portions of a cell. The results suggest that if life similar to that on Earth exists on these planetary bodies, that this life should be detectable by instruments launching in the fall.

Tudor era horse cemetery in Westminster revealed as likely resting place for elite imported animals      (via sciencedaily.com)     Original source 

Archaeological analysis of a near unique animal cemetery discovered in London nearly 30 years ago has revealed there was an international horse trading network, orchestrated by the elites of late medieval and Tudor England, which brought superior physical specimens to the UK for jousting and for use as status symbols.

Researchers name prehistoric amphibian ancestor discovered in Smithsonian collection after Kermit the Frog      (via sciencedaily.com)     Original source 

Scientists have uncovered the fossilized skull of a 270-million-year-old ancient amphibian ancestor in the collection of the Smithsonian's National Museum of Natural History. The team of researchers described the fossil as a new species of proto-amphibian, which they named Kermitops gratus in honor of the iconic Muppet, Kermit the Frog.

Heat to blame for space pebble demise      (via sciencedaily.com)     Original source 

The dust of comets fills the space between the planets, collectively called the zodiacal cloud. Still, severe breakdown has reduced that dust in size so much that it now scatters sunlight efficiently, causing the faint glow in the night sky known as the 'zodiacal light.' It was long thought that high-speed collisions pulverized the comet ejecta, but now a team of researchers reports that heat is to blame.

Decoding the plant world's complex biochemical communication networks      (via sciencedaily.com)     Original source 

A research team has begun translating the complex molecular language of petunias. Their grammar and vocabulary are well hidden, however, within the countless proteins and other compounds that fill floral cells. Being rooted to the ground, plants can't run away from insects, pathogens or other threats to their survival. But plant scientists have long known that they do send warnings to each other via scent chemicals called volatile organic compounds.

Deep Earth electrical grid mystery solved      (via sciencedaily.com)     Original source 

To 'breathe' in an environment without oxygen, bacteria in the ground beneath our feet depend upon a single family of proteins to transfer excess electrons, produced during the 'burning' of nutrients, to electric hairs called nanowires projecting from their surface.

Scientists find one of the most ancient stars that formed in another galaxy      (via sciencedaily.com)     Original source 

The first generation of stars transformed the universe. Inside their cores, simple hydrogen and helium fused into a rainbow of elements. When these stars died, they exploded and sent these new elements across the universe. The iron running in your veins and the calcium in your teeth and the sodium powering your thoughts were all born in the heart of a long-dead star.

Robotic metamaterial: An endless domino effect      (via sciencedaily.com)     Original source 

If it walks like a particle, and talks like a particle... it may still not be a particle. A topological soliton is a special type of wave or dislocation which behaves like a particle: it can move around but cannot spread out and disappear like you would expect from, say, a ripple on the surface of a pond. Researchers now demonstrate the atypical behavior of topological solitons in a robotic metamaterial, something which in the future may be used to control how robots move, sense their surroundings and communicate.

Scientists have created a giant quantum vortex to mimic a black hole in superfluid helium that has allowed them to see in greater detail how analogue black holes behave and interact with their surroundings.

Study reveals 'cozy domesticity' of prehistoric stilt-house dwellers in England's ancient marshland      (via sciencedaily.com)     Original source 

Detailed reports on thousands of artifacts pulled from 'Britain's Pompeii' reveals the surprisingly sophisticated domestic lives of Bronze Age Fen folk some 3,000 years ago -- from home interiors to recipes, clothing, kitchenware and pets.

Astrophysicist's research could provide a hint in the search for dark matter      (via sciencedaily.com)     Original source 

Dark matter is one of science's greatest mysteries. Although it is believed to make up about 85 percent of the cosmos, scientists know very little about its fundamental nature. Research provides some of the most stringent constraints on the nature of dark matter yet. It also revealed a small hint of a signal that, if real, could be confirmed in the next decade or so.

New archive of ancient human brains challenges misconceptions of soft tissue preservation      (via sciencedaily.com)     Original source 

A new study has challenged previously held views that brain preservation in the archaeological record is extremely rare. The team compiled a new archive of preserved human brains, which highlighted that nervous tissues actually persist in much greater abundances than traditionally thought, assisted by conditions that prevent decay.
