Published Fiddler crab eye view inspires researchers to develop novel artificial vision
(via sciencedaily.com) Artificial vision systems are implemented in motion sensing, object detection, and self-driving vehicles. However, they are not suitable for changing external environments and are limited to a hemispherical field-of-view (FOV). Addressing this issue, researchers have now developed a novel artificial vision with 360-degree FOV that can image both terrestrial and aquatic environments. The system, modeled after the eye structure of the fiddler crab, could help realize the all-weather vision and panoramic object detection.
Published Space travel: Bone aging in fast forward
(via sciencedaily.com) Long periods in space damage bone structure irreparably in some cases and can make parts of the human skeleton age prematurely by up to 10 years, according to new research. Adapted training programs in conjunction with medication could provide better protection for astronauts on future space missions. The research findings also have implications for treating rheumatic conditions in clinical practice.
Published A paper battery with water switch
(via sciencedaily.com) A team of researchers has developed a water-activated disposable paper battery. The researchers suggest that it could be used to power a wide range of low-power, single-use disposable electronics -- such as smart labels for tracking objects, environmental sensors and medical diagnostic devices -- and minimize their environmental impact.
Published Taking your time makes a difference
(via sciencedaily.com) Researchers find that stem cells in the developing brain of modern humans take longer to divide and make fewer errors when distributing their chromosomes to their daughter cells, compared to those of Neanderthals.
Published New bioremediation material to clean up 'forever chemicals'
(via sciencedaily.com) Original source A novel bioremediation technology for cleaning up per- and polyfluoroalkyl substances, or PFAS, chemical pollutants that threaten human health and ecosystem sustainability, has been developed. The material has potential for commercial application for disposing of PFAS, also known as 'forever chemicals.'
Published Listening to the people results in a more sustainable future energy system
(via sciencedaily.com) By taking into account the demographics and preferences of US racial groups, clarified through a nationally representative survey of 3,000 US residents, researchers have created a 'desirable' electricity generation mix for 2050 that includes 50% more energy from renewables than current projections. Combining such bottom-up input with top-down energy system goals set by policymakers could help meet both the needs and preferences of the population along with emission and climate goals.
Published Octopus lures from the Mariana Islands found to be oldest in the world
(via sciencedaily.com) An archaeological study has determined that cowrie-shell artifacts found throughout the Mariana Islands were lures used for hunting octopuses and that the devices, similar versions of which have been found on islands across the Pacific, are the oldest known artifacts of their kind in the world.
Published New Antarctic study shows levels of 'forever chemicals' reaching the remote continent have been increasing
(via sciencedaily.com) New evidence from Antarctica shows that toxic 'fluorinated forever chemicals' have increased markedly in the remote environment in recent decades and scientists believe CFC-replacements could be among likely sources.
Published Engineers develop stickers that can see inside the body
(via sciencedaily.com) Engineers designed an adhesive patch that produces ultrasound images of the body. The stamp-sized device sticks to skin and can provide continuous ultrasound imaging of internal organs for 48 hours.
Published How charred detritus dispersed from Goleta Beach in wake of 2018 Montecito, California, debris flow
(via sciencedaily.com) The catastrophic debris flow that affected Montecito, Calif., in early January, 2018 was the result of a rare confluence of severe events. The Thomas Fire had been raging for weeks in Ventura and Santa Barbara counties, and an unusually strong winter storm dumped half an inch of rain in five minutes on the newly-charred hills above the suburban enclave. With the tough vegetation that holds the hillsides in place burned off by the fire, tons of water, silt, burnt plant matter and rocks roared down the slopes and engulfed the community below, causing massive damage and the death of 23 residents.
Published Burro-ing into the past
(via sciencedaily.com) A new study reveals that introduced donkeys and indigenous pumas are helping to resurrect extinct food webs in Death Valley.
Published Magnetic quantum material broadens platform for probing next-gen information technologies
(via sciencedaily.com) Scientists have used neutron scattering to determine whether a specific material's atomic structure could host a novel state of matter called a spiral spin liquid. By tracking tiny magnetic moments known as 'spins' on the honeycomb lattice of a layered iron trichloride magnet, the team found the first 2D system to host a spiral spin liquid.
Published Graphene scientists capture images of atoms 'swimming' in liquid
(via sciencedaily.com) Graphene scientists have created a novel 'nano-petri dish' using two-dimensional (2D) materials to create a new method of observing how atoms move in liquid.
Published Smoke from Western wildfires can influence Arctic sea ice
(via sciencedaily.com) Sea ice and wildfires may be more interconnected than previously thought, according to new research.
Published Oldest DNA from domesticated American horse lends credence to shipwreck folklore
(via sciencedaily.com) Feral horses have roamed freely across the island of Assateague off the coast of Maryland and Virginia for hundreds of years, but exactly how they got there has remained a mystery. In a new study, ancient DNA extracted from a 16th century cow tooth from one of Spain's first Caribbean colonies turns out to be from a horse. Analysis of the DNA suggest that old folk tales claiming that horses were marooned on Assateague following the shipwreck of a Spanish galleon are likely more fact than fiction.
Published Ancient DNA clarifies the early history of American colonial horses
(via sciencedaily.com) A newly identified 16th century horse specimen is among the oldest domestic horses from the Americas known to date, and its DNA helps clarify the history of horses in the Western Hemisphere, according to a new study.
Published High-status Danish Vikings wore exotic beaver furs
(via sciencedaily.com) Beaver fur was a symbol of wealth and an important trade item in 10th Century Denmark, according to a new study.
Published Western U.S. wildfire smoke plumes are getting taller, researchers find
(via sciencedaily.com) In recent years the plumes of smoke crawling upward from Western wildfires have trended taller, with more smoke and aerosols lofted up where they can spread farther and impact air quality over a wider area. The likely cause is climate change, with decreased precipitation and increased aridity in the Western U.S. that intensifies wildfire activity.
Published A key role for quantum entanglement
(via sciencedaily.com) A method known as quantum key distribution has long held the promise of communication security unattainable in conventional cryptography. An international team of scientists has now demonstrated experimentally, for the first time, an approach to quantum key distribution that is based on high-quality quantum entanglement -- offering much broader security guarantees than previous schemes.
Published Quantum cryptography: Hacking is futile
(via sciencedaily.com) An international team has successfully implemented an advanced form of quantum cryptography for the first time. Moreover, encryption is independent of the quantum device used and therefore even more secure against hacking attempts.
