Published Mapped: 33 new big game migrations across American West
(via sciencedaily.com) Original source A new set of maps that document the movements of ungulates was published today in the fourth volume of the Ungulate Migrations of the Western United States. The maps in this collaborative report series reveal the migration routes and critical ranges used by ungulates, or hooved mammals, in the western U.S., furthering scientists' understanding of the geography of big game migrations.
Published Ants in Colorado are on the move due to climate change
(via sciencedaily.com) Original source Ant species living in Boulder's foothills have shifted their habitat over the last six decades, potentially affecting local ecosystems, suggests a new study.
Published Quantum breakthrough when light makes materials magnetic
(via sciencedaily.com) Original source The potential of quantum technology is huge but is today largely limited to the extremely cold environments of laboratories. Now, researchers have succeeded in demonstrating for the very first time how laser light can induce quantum behavior at room temperature -- and make non-magnetic materials magnetic. The breakthrough is expected to pave the way for faster and more energy-efficient computers, information transfer and data storage.
Published Breakthrough for next-generation digital displays
(via sciencedaily.com) Original source Researchers have developed a digital display screen where the LEDs themselves react to touch, light, fingerprints and the user's pulse, among other things. Their results could be the start of a whole new generation of displays for phones, computers and tablets.
Published What's quieter than a fish? A school of them
(via sciencedaily.com) Original source Swimming in schools makes fish surprisingly stealthy underwater, with a group able to sound like a single fish. Engineers working with a high-tech simulation of schooling mackerel offer new insight into why fish swim in schools and promise for the design and operation of much quieter submarines and autonomous undersea vehicles.
Published 'Teacher Toads' can save native animals from toxic cane toads
(via sciencedaily.com) Original source Scientists from Macquarie University have come up with an innovative way to stop cane toads killing native wildlife by training goannas to avoid eating the deadly amphibians.
Published Could new technique for 'curving' light be the secret to improved wireless communication?
(via sciencedaily.com) Original source A study that could help revolutionize wireless communication introduces a novel method to curve terahertz signals around an obstacle.
Published Will the convergence of light and matter in Janus particles transcend performance limitations in the optical display industry?
(via sciencedaily.com) Original source Team successfully exerted electrical control over polaritons, hybridized light-matter particles, at room temperature.
Published New four-terminal tandem organic solar cell achieves 16.94% power conversion efficiency
(via sciencedaily.com) Original source Researchers have fabricated a new four-terminal organic solar cell with a tandem configuration with a 16.94% power conversion efficiency (PCE). The new device is composed by a highly transparent front cell that incorporates a transparent ultrathin silver (Ag) electrode of only 7nm, which ensures its efficient operation.
Published Innovative sensing platform unlocks ultrahigh sensitivity in conventional sensors
(via sciencedaily.com) Original source Engineers unlock the power of exceptional points (EPs) for advanced optical sensing. EPs -- specific conditions in systems where extraordinary optical phenomena can occur -- can be deployed on conventional sensors to achieve a striking sensitivity to environmental perturbations.
Published Dinosaur study challenges Bergmann's rule
(via sciencedaily.com) Original source A new study calls into question Bergmann's rule, an 1800s-era scientific principle stating that animals in high-latitude, cooler climates tend to be larger than close relatives living in warmer climates.
Published Heat stress from ocean warming harms octopus vision
(via sciencedaily.com) Original source While climate change has led to an increase in the abundance of octopuses, heat stress from projected ocean warming could impair their vision and impact the survivability of the species.
Published Four in five bird species cannot tolerate intense human pressures
(via sciencedaily.com) Original source In a recent study, researchers found that 78% of the world's bird species do not thrive in the most modified human-dominated environments. These species are also most likely to have declining populations.
Published Kerr-enhanced optical spring for next-generation gravitational wave detectors
(via sciencedaily.com) Original source A novel technique for enhancing optical spring that utilizes the Kerr effect to improve the sensitivity of gravitational wave detectors (GWDs) has recently been developed. This innovative design uses optical non-linear effects from the Kerr effect in the Fabry-Perot cavity to achieve high signal amplification ratios and optical spring constant, with potential applications in not only GWDs but also in a range of optomechanical systems.
Published Rusty-patched bumblebee's struggle for survival found in its genes
(via sciencedaily.com) Original source The rusty-patched bumblebee, once common in the United States, has declined from about 90% of its former range. Researchers conducted the first range-wide genetic study of the endangered species to inform recovery efforts.
Published Demand for critical minerals puts African Great Apes at risk
(via sciencedaily.com) Original source A recent study shows that the threat of mining to the great ape population in Africa has been greatly underestimated.
Published Researchers visualize quantum effects in electron waves
(via sciencedaily.com) Original source One of the most fundamental interactions in physics is that of electrons and light. In an experiment, scientists have now managed to observe what is known as the Kapitza-Dirac effect for the first time in full temporal resolution. This effect was first postulated over 90 years ago, but only now are its finest details coming to light.
Published More social birds are more adventurous feeders
(via sciencedaily.com) Original source A new study has found that birds that are more social are more likely to use novel sources of food.
Published Intelligent liquid
(via sciencedaily.com) Original source Researchers have developed a programmable meta-fluid with tunable springiness, optical properties, viscosity and even the ability to transition between a Newtonian and non-Newtonian fluid. The first-of-its-kind meta-fluid uses a suspension of small, elastomer spheres -- between 50 to 500 microns -- that buckle under pressure, radically changing the characteristics of the fluid. The meta-fluid could be used in everything from hydraulic actuators to program robots, to intelligent shock absorbers that can dissipate energy depending on the intensity of the impact, to optical devices that can transition from clear to opaque.
Published Sunrise to sunset, new window coating blocks heat -- not view
(via sciencedaily.com) Original source Windows welcome light into interior spaces, but they also bring in unwanted heat. A new window coating blocks heat-generating ultraviolet and infrared light and lets through visible light, regardless of the sun's angle. The coating can be incorporated onto existing windows or automobiles and can reduce air-conditioning cooling costs by more than one-third in hot climates.
