Published Pancake stack of films on a balloon most accurate gamma-ray telescope
(via sciencedaily.com) Original source A pancake stack of radioactivity-sensitive films carried through the sky by a balloon was able to take the world's most accurate picture of a neutron star's gamma ray beam. To achieve this, researchers combined the oldest method of capturing radioactive radiation with the newest data capturing techniques and a clever time-recording device.
Published Insects already had a variety of defense strategies in the Cretaceous
(via sciencedaily.com) Original source Analyses of amber show that insect larvae were already using a wide variety of tactics to protect themselves from predators 100 million years ago.
Published Blue PHOLEDs: Final color of efficient OLEDs finally viable in lighting
(via sciencedaily.com) Original source Lights could soon use the full color suite of perfectly efficient organic light-emitting diodes, or OLEDs, that last tens of thousands of hours. The new phosphorescent OLEDs, commonly referred to as PHOLEDs, can maintain 90% of the blue light intensity for 10-14 times longer than other designs that emit similar deep blue colors. That kind of lifespan could finally make blue PHOLEDs hardy enough to be commercially viable in lights that meet the Department of Energy's 50,000-hour lifetime target. Without a stable blue PHOLED, OLED lights need to use less-efficient technology to create white light.
Published 360-degree head-up display view could warn drivers of road obstacles in real time
(via sciencedaily.com) Original source Researchers have developed an augmented reality head-up display that could improve road safety by displaying potential hazards as high-resolution three-dimensional holograms directly in a driver's field of vision in real time.
Published Aerogel can become the key to future terahertz technologies
(via sciencedaily.com) Original source High-frequency terahertz waves have great potential for a number of applications including next-generation medical imaging and communication. Researchers have shown that the transmission of terahertz light through an aerogel made of cellulose and a conducting polymer can be tuned. This is an important step to unlock more applications for terahertz waves.
Published Unveiling ancient secrets: 3D preservation of trilobite soft tissues sheds light on convergent evolution of defensive enrollment
(via sciencedaily.com) Original source Researchers describe unusual trilobite fossils prepared as thin sections showing the 3D soft tissues during enrollment. The study reveals the soft undersides of enrolled trilobites and the evolutionary mechanism that allows arthropods to enroll their bodies for protection from predators and adverse environmental conditions.
Published Mysterious fruit shown to be the oldest known fossils of the Frankincense and Myrrh family
(via sciencedaily.com) Original source Early in the 1970s, paleontologists discovered strange fossilized fruits between hardened rock from one of the largest volcanic eruptions in Earth's history. The identity of these fossils remained elusive for the next several decades. Using CT scanning, scientists have now determined they are the oldest fossils from species in the Frankincense and Myrrh family.
Published Snowflakes swirling in turbulent air as they fall through a laser light sheet
(via sciencedaily.com) Original source A winter wonderland calls to mind piles of fluffy, glistening snow. But to reach the ground, snowflakes are swept into the turbulent atmosphere, swirling through the air instead of plummeting directly to the ground. Researchers found that regardless of turbulence or snowflake type, acceleration follows a universal statistical pattern that can be described as an exponential distribution.
Published Gentle x-ray imaging of small living specimens
(via sciencedaily.com) Original source Researchers all over Germany have developed a new system for X-ray imaging, which is suited for both living specimens and sensitive materials. The system records images of micrometer resolution at a minimum radiation dose. In a pilot study, the researchers tested their method on living parasitic wasps and observed them for more than 30 minutes.
Published First observation of how water molecules move near a metal electrode
(via sciencedaily.com) Original source A collaborative team of experimental and computational physical chemists has made an important discovery in the field of electrochemistry, shedding light on the movement of water molecules near metal electrodes. This research holds profound implications for the advancement of next-generation batteries utilizing aqueous electrolytes.
Published Ultrafast lasers map electrons 'going ballistic' in graphene, with implications for next-gen electronic devices
(via sciencedaily.com) Original source Research reveals the ballistic movement of electrons in graphene in real time. The observations could lead to breakthroughs in governing electrons in semiconductors, fundamental components in most information and energy technology.
Published Morocco earthquake had unusual deep slip, according to new modeling
(via sciencedaily.com) Original source In their rapid characterization of the magnitude 6.8 Al Haouz earthquake in Morocco, researchers suggest that the earthquake ruptured roughly 25 kilometers deep beneath the surface.
Published A promising pairing: Scientists demonstrate new combination of materials for quantum science
(via sciencedaily.com) Original source For the first time, scientists publish results on a new chip composed of diamond and lithium niobate. The results demonstrate the combination as a promising candidate for quantum devices.
Published AI provides more accurate analysis of prehistoric and modern animals, painting picture of ancient world
(via sciencedaily.com) Original source A new study of the remains of prehistoric and modern African antelopes found that AI technology accurately identified animals more than 90% of the time compared to humans, who had much lower accuracy rates depending on the expert.
Published This next generation blue light could potentially promote or hinder sleep on command
(via sciencedaily.com) Original source Blue light from LED lamps and consumer electronics can mess with your sleep because it disrupts production of the natural sleep hormone melatonin. Tinted glasses or displays in night mode can mask, but don't remove, a portion of the disruptive wavelengths. But now, researchers report that they have designed more 'human-centric' LEDs that could potentially enhance drowsiness or alertness on command.
Published Researchers create stable hybrid laser by 3D printing micro-optics onto fibers
(via sciencedaily.com) Original source For the first time, researchers have shown that 3D-printed polymer-based micro-optics can withstand the heat and power levels that occur inside a laser. The advance enables inexpensive compact and stable laser sources that would be useful in a variety of applications, including the lidar systems used for autonomous vehicles.
Published Best areas for rewilding European bison
(via sciencedaily.com) Original source Simulations integrate historical records, fossils, and ancient DNA to reveal why the European bison nearly went extinct, and pinpoint optimal areas for conservation. Since the near-extinction of the European bison, enormous conservation efforts have helped to restore wild populations, and its numbers are on the rise. However, the study authors argue that ensuring the species's long-term protection and recovery requires understanding why they nearly went extinct in the first place. 'Our study also suggests areas where rewilding attempts are most likely to be successful,' said lead author July Pilowsky, currently a disease ecologist at Cary Institute of Ecosystem Studies. Pilowsky completed the research while working on their PhD at University of Adelaide and University of Copenhagen.
