Published Engineers develop breakthrough 'robot skin'
(via sciencedaily.com)
Original source 
Smart, stretchable and highly sensitive, a new soft sensor opens the door to a wide range of applications in robotics and prosthetics. When applied to the surface of a prosthetic arm or a robotic limb, the sensor skin provides touch sensitivity and dexterity, enabling tasks that can be difficult for machines such as picking up a piece of soft fruit. The sensor is also soft to the touch, like human skin, which helps make human interactions safer and more lifelike.
Published Roosters might recognize themselves in the mirror
(via sciencedaily.com)
Original source 
Scrape, cluck, lay eggs -- that's it? Anyone involved in chicken farming knows that the animals are capable of much more. Researchers have found evidence that roosters could recognize themselves in a mirror. Whether this is successful, however, depends on the experimental conditions -- a finding that points beyond the experiment with roosters and could also be of importance for other animal species.
Published Uranus aurora discovery offers clues to habitable icy worlds
(via sciencedaily.com)
Original source 
Astronomers confirm the existence of an infrared (IR) aurora on Uranus. This could help astronomers identify exoplanets that might support life, a large number of which are icy worlds.
Published Shape-shifting fiber can produce morphing fabrics
(via sciencedaily.com)
Original source 
FibeRobo is a liquid crystal elastomer fiber that can change its shape in response to thermal stimuli. Compatible with existing textile manufacturing machinery, it could be used to make morphing textiles, like a jacket that changes its insulating properties.
Published Rider on the storm: Shearwater seabird catches an 11 hour ride over 1,000 miles in a typhoon
(via sciencedaily.com)
Original source 
New research suggests that increasingly severe weather driven by climate change may push oceangoing seabirds to their limits.
Published Massive space explosion observed creating elements needed for life
(via sciencedaily.com)
Original source 
Scientists have observed the creation of rare chemical elements in the second-brightest gamma-ray burst ever seen -- casting new light on how heavy elements are made.
Published Scientists discover molten layer covering Martian core
(via sciencedaily.com)
Original source 
NASA's InSight mission to Mars helped scientists map out Mars' internal structure, including the size and composition of its core, and provided general hints about its tumultuous formation. But findings from a new paper could lead to reanalysis of that data. An international team of researchers discovered the presence of a molten silicate layer overlying Mars' metallic core -- providing new insights into how Mars formed, evolved and became the barren planet it is today.
Published 'Dim-witted' pigeons use the same principles as AI to solve tasks
(via sciencedaily.com)
Original source 
A new study provides evidence that pigeons tackle some problems just as artificial intelligence would -- allowing them to solve difficult tasks that would vex humans.
Published Bizarre new fossils shed light on ancient plankton
(via sciencedaily.com)
Original source 
Recently discovered microfossils date back half a billion years. Resembling modern-day algae, they provide insight into early life in our oceans.
Published Raining cats and dogs: Global precipitation patterns a driver for animal diversity
(via sciencedaily.com)
Original source 
A team has identified several factors to help answer a fundamental ecological question: why is there a ridiculous abundance of species some places on earth and a scarcity in others? What factors, exactly, drive animal diversity? They discovered that what an animal eats (and how that interacts with climate) shapes Earth's diversity.
Published Finding the genes that help kingfishers dive without hurting their brains
(via sciencedaily.com)
Original source 
Scientists studied the genomes of 30 kingfisher species to try to identify the genes that allow kingfishers to dive headfirst into water without huring their brains. The researchers found that the diving birds have unusual mutations to the genes that produce tau: a protein that helps stabilize tiny structures in the brain, but which can build up in humans with traumatic brain injuries or Alzheimer's disease. The researchers suspect that these variations in the kingfishers' tau proteins might protect their brains when they dive.
Published Astrophysicists scan the Galaxy for signs of life
(via sciencedaily.com)
Original source 
Astrophysicists are scanning the Universe for 'technosignatures' emanating from distant planets that would provide support for the existence of intelligent, alien life. Researchers plan to monitor millions of star systems.
Published Origin of ancient mummified baboons found in Egypt
(via sciencedaily.com)
Original source 
Primatologists are using genetic analysis to determine the geographic origin of ancient mummified baboons found in Egypt. The team finds evidence that the two legendary trading regions of Punt and Adulis may have been the same place separated by a thousand years of history.
Published How quantum light 'sees' quantum sound
(via sciencedaily.com)
Original source 
Researchers have proposed a new way of using quantum light to 'see' quantum sound. A new paper reveals the quantum-mechanical interplay between vibrations and particles of light, known as photons, in molecules. It is hoped that the discovery may help scientists better understand the interactions between light and matter on molecular scales. And it potentially paves the way for addressing fundamental questions about the importance of quantum effects in applications ranging from new quantum technologies to biological systems.
Published Researchers probe how a piece of the moon became a near-Earth asteroid
(via sciencedaily.com)
Original source 
Two years after the striking discovery that a near-Earth asteroid could be a chunk of the moon, another UArizona research group has found that a rare pathway could have enabled this to happen.
Published LIGO surpasses the quantum limit
(via sciencedaily.com)
Original source 
Researchers report a significant advance in quantum squeezing, which allows them to measure undulations in space-time across the entire range of gravitational frequencies detected by LIGO.
Published Plants transformed into detectors of dangerous chemicals
(via sciencedaily.com)
Original source 
What if your house plant could tell you your water isn't safe? Scientists are closer to realizing this vision, having successfully engineered a plant to turn beet red in the presence of a banned, toxic pesticide.
Published Plant-based materials give 'life' to tiny soft robots
(via sciencedaily.com)
Original source 
A team of researchers has created smart, advanced materials that will be the building blocks for a future generation of soft medical microrobots. These tiny robots have the potential to conduct medical procedures, such as biopsy, and cell and tissue transport, in a minimally invasive fashion.
Published Simulating cold sensation without actual cooling
(via sciencedaily.com)
Original source 
The perception of persistent thermal sensations, such as changes in temperature, tends to gradually diminish in intensity as our bodies become accustomed to the temperature. This phenomenon leads to a shift in our perception of temperature when transitioning between different scenes in a virtual environment. Researchers have now developed a technology to generate a virtual cold sensation via a non-contact method without physically altering the skin temperature.
Published Fungal evolution discovered: Mycena can now invade living hosts
(via sciencedaily.com)
Original source 
Biologists have long known mushrooms of the genus Mycena, commonly known as bonnet mushrooms, as fungi that live off of dead trees and plants. New research demonstrates that bonnets can also find their ways into young, healthy trees and plants, where they try to cooperate. In doing so, they have made an evolutionary leap which challenges our understanding of the ecological roles of fungi.
