Scientists on the hunt for evidence of quantum gravity's existence at the South Pole      (via sciencedaily.com)     Original source 

An Antarctic large-scale experiment is striving to find out if gravity also exists at the quantum level. An extraordinary particle able to travel undisturbed through space seems to hold the answer.

Uncovering the mystery of Dorset's Cerne Giant      (via sciencedaily.com)     Original source 

For centuries, the Cerne Giant, a figure carved into a hillside in Dorset, has fascinated locals and visitors to the area. A new paper proposes that the Cerne Giant can in fact be dated to the early Middle Ages, and, as a result, its cultural context and significance more clearly understood.

A self-cleaning wall paint      (via sciencedaily.com)     Original source 

Beautiful white wall paint does not stay beautiful and white forever. Often, various substances from the air accumulate on its surface. This can be a desired effect because it makes the air cleaner for a while -- but over time, the color changes and needs to be renewed. Now, special titanium oxide nanoparticles have been developed that can be added to ordinary, commercially available wall paint to establish self-cleaning power: The nanoparticles are photocatalytically active, they can use sunlight not only to bind substances from the air, but also to decompose them afterwards.

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.

Rays were more diverse 150 million years ago than previously thought      (via sciencedaily.com)     Original source 

Scientists have explored the puzzling world of rays that lived 150 million years ago and discovered a previously hidden diversity -- including a new ray species. This study significantly expands the understanding of these ancient cartilaginous fish and provides further insights into a past marine ecosystem.

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.
