Published Colliding neutron stars provide a new way to measure the expansion of the Universe
(via sciencedaily.com) Original source In recent years, astronomy has seen itself in a bit of crisis: Although we know that the Universe expands, and although we know approximately how fast, the two primary ways to measure this expansion do not agree. Now astrophysicists suggest a novel method which may help resolve this tension.
Published Skin behind the ears and between the toes can host a collection of unhealthy microbes
(via sciencedaily.com) Original source Scrubbing behind the ears and between the toes may help keep the skin in those regions healthy, new research suggests. The microbiome, or the collection of microbes living on and in the human body, are known to play a role in human health and the skin is no different. A new study has shown that the composition of the skin microbiome varies across dry, moist and oily regions of the skin.
Published Solving a sticky, life-threatening problem
(via sciencedaily.com) Original source Researchers have zeroed in on C. auris' uncanny ability to stick to everything from skin to catheters and made a startling discovery: it uses a protein similar to that used by barnacles and mollusks.
Published Polyps as pixels: Innovative technique maps biochemistry of coral reefs
(via sciencedaily.com) Original source Using an innovative new approach to sampling corals, researchers are now able to create maps of coral biochemistry that reveal with unprecedented detail the distribution of compounds that are integral to the healthy functioning of reefs.
Published Wild Asian elephants display unique puzzle solving skills
(via sciencedaily.com) Original source A new study has documented the abilities of individual wild Asian elephants to access food by solving puzzles that unlocked storage boxes. It is the first research study to show that individual wild elephants have different willingness and abilities to problem solve in order to get food.
Published Boo to a goose -- new animal behaviour tech aims to save wildlife
(via sciencedaily.com) Original source Facial recognition software used to study the social behavior of individual Greylag Geese in Europe will soon be used to monitor one of the rarest geese in the world, the Cape Barren Goose in South Australia. The technology was used to assess how each bird responds to images of themselves, other flock mates or partners and researchers say it could be used by other scientists or in citizen science apps around the world to monitor and record endangered wildlife or even to promote the welfare of animals in captivity.
Published Scientists unveil fire-safe fuel
(via sciencedaily.com) Original source Chemical engineers have designed a fuel that ignites only with the application of electric current. Since it doesn't react to flames and cannot start accidental fires during storage or transport, it is a 'safe' liquid fuel.
Published Why are killer whales harassing and killing porpoises without eating them?
(via sciencedaily.com) Original source For decades, fish-eating killer whales in the Pacific Northwest have been observed harassing and even killing porpoises without consuming them —- a perplexing behavior that has long intrigued scientists.
Published Whales Around the World Play With Kelp Clumps
(via sciencedaily.com) Original source A new article has analyzed another understudied behavior in baleen (filter-feeding) whales such as humpback whales in different populations across the northern and southern hemispheres. They appeared to roll around and 'play' with clumps of kelp and seaweed at the water's surface. The research also emphasizes that the behavior was similar in different individuals, regardless of where in the world it occurred.
Published Extreme weight loss: Star sheds unexpected amounts of mass just before going supernova
(via sciencedaily.com) Original source A newly discovered nearby supernova whose star ejected up to a full solar mass of material in the year prior to its explosion is challenging the standard theory of stellar evolution. The new observations are giving astronomers new insight into what happens in the final year prior to a star's death and explosion.
Published Strength is in this glass's DNA
(via sciencedaily.com) Original source Scientists were able to fabricate a pure form of glass and coat specialized pieces of DNA with it to create a material that was not only stronger than steel, but incredibly lightweight.
Published Down goes antimatter! Gravity's effect on matter's elusive twin is revealed
(via sciencedaily.com) For the first time, in a unique laboratory experiment at CERN, researchers have observed individual atoms of antihydrogen fall under the effects of gravity. In confirming antimatter and regular matter are gravitationally attracted, the finding rules out gravitational repulsion as the reason why antimatter is largely missing from the observable universe.
Published Powering the quantum revolution: Quantum engines on the horizon
(via sciencedaily.com) Original source Scientists unveil exciting possibilities for the development of highly efficient quantum devices.
Published New proof for black hole spin
(via sciencedaily.com) Original source The supermassive black hole at the heart of galaxy M87, made famous by the first picture of a black hole shadow, has yielded another first: the jet shooting out from the black hole has been confirmed to wobble, providing direct proof that the black hole is spinning.
Published One-hour training is all you need to control a third robotic arm, study finds
(via sciencedaily.com) A new study has found that people can learn to use supernumerary robotic arms as effectively as working with a partner in just one hour of training.
Published New insights into the atmosphere and star of an exoplanet
(via sciencedaily.com) A new study of the intriguing TRAPPIST-1 exoplanetary system has demonstrated the complex interaction between the activity of the system's star and its planetary features.
Published Hidden supermassive black holes reveal their secrets through radio signals
(via sciencedaily.com) Astronomers have found a striking link between the amount of dust surrounding a supermassive black hole and the strength of the radio emission produced in extremely bright galaxies.
Published Jellyfish, with no central brain, shown to learn from past experience
(via sciencedaily.com) Original source Even without a central brain, jellyfish can learn from past experiences like humans, mice, and flies, scientists report for the first time. They trained Caribbean box jellyfish (Tripedalia cystophora) to learn to spot and dodge obstacles. The study challenges previous notions that advanced learning requires a centralized brain and sheds light on the evolutionary roots of learning and memory.
Published Astronomers discover newborn galaxies with the James Webb Space Telescope
(via sciencedaily.com) With the launch of the James Webb Space Telescope, astronomers are now able to peer so far back in time that we are approaching the epoch where we think that the first galaxies were created. Throughout most of the history of the Universe, galaxies seemingly tend to follow a tight relation between how many stars they have formed, and how many heavy elements they have formed. But for the first time we now see signs that this relation between the amount of stars and elements does not hold for the earliest galaxies. The reason is likely that these galaxies simply are in the process of being created, and have not yet had the time to create the heavy elements.
Published Astronomers find abundance of Milky Way-like Galaxies in early Universe, rewriting cosmic evolution theories
(via sciencedaily.com) Galaxies from the early Universe are more like our own Milky Way than previously thought, flipping the entire narrative of how scientists think about structure formation in the Universe, according to new research.
