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 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 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 Conversations with plants: Can we provide plants with advance warning of impending dangers?
(via sciencedaily.com) Original source Plant scientists have engineered a light-controlled gene expression system (optogenetics system) from a prokaryotic system into a eukaryotic system that is tailored for plants.
Published This parasitic plant convinces hosts to grow into its own flesh--it's also an extreme example of genome shrinkage
(via sciencedaily.com) Original source Balanophora shed one third of its genes as it evolved into a streamlined parasitic plant -- an extreme degree of genome shrinkage even among parasites. Along the way this subtropical plant developed the ability to induce the host plant to grow into the parasite's own flesh -- forming chimeric organs that mix host and parasite tissues.
Published Dinosaur feathers reveal traces of ancient proteins
(via sciencedaily.com) Original source Palaeontologists have discovered X-ray evidence of proteins in fossil feathers that sheds new light on feather evolution.
Published Ritual use of human remains dating from the Neolithic
(via sciencedaily.com) Original source An international study has documented post-mortem bone modifications not linked to consumption.
Published Scientists successfully maneuver robot through living lung tissue
(via sciencedaily.com) Scientists have shown that their steerable lung robot can autonomously maneuver the intricacies of the lung, while avoiding important lung structures.
Published New Mars gravity analysis improves understanding of possible ancient ocean
(via sciencedaily.com) Original source The first use of a novel method of analyzing Mars' gravitational force supports the idea that the planet once had an extensive northern ocean. In doing so, the method defines the scope of what scientists refer to as the northern Martian paleo-ocean in more detail.
Published Researchers make sand that flows uphill
(via sciencedaily.com) Engineering researchers have discovered that sand can actually flow uphill. A corresponding video shows what happens when torque and an attractive force is applied to each grain -- the grains flow uphill, up walls, and up and down stairs.
