Published Global inventory of sound production brings us one step closer to understanding aquatic ecosystems
(via sciencedaily.com) Original source Our understanding of which aquatic species produce sounds just took a big step forward. Scientists have created an inventory of species confirmed or expected to produce sound underwater.
Published Hotter weather caused by climate change could mean more mosquitoesv
(via sciencedaily.com) Original source Research along James River in Richmond suggests that climate change could shorten window for predators to prey on larvae.
Published Scientists collect aardvark poop to understand how the species is impacted by climate in Africa
(via sciencedaily.com) Original source In a new study of aardvarks, researchers spent months in sub-Saharan Africa collecting poop from the animal and concluded that aridification of the landscape is isolating them, which they say could have implications for their long-term survival.
Published New method could help estimate wildlife disease spread
(via sciencedaily.com) Original source A new method could be used to estimate the prevalence of disease in free-ranging wildlife and help determine how many samples are needed to detect a disease.
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 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 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 Earliest evidence for domestic yak found using both archaeology, ancient DNA
(via sciencedaily.com) Original source The high-altitude hero of the Himalayas, yak are among the few large animals that can survive the extremely cold, harsh and oxygen-poor conditions of the Tibetan Plateau. In the mountainous regions of Asia, yak and yak-cattle hybrids serve as vital sources of meat, milk, transportation and fuel. However, little is known about their history: when or where yak were domesticated. In a new study, researchers report archaeologically and genetically confirmed evidence for domestic yak, dating back 2,500 years, by far the oldest record.
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 Trees in wetter regions more sensitive to drought
(via sciencedaily.com) Original source This holiday season brings surprising news about your Christmas tree. Scientists just discovered that globally, trees growing in wetter regions are more sensitive to drought. That means if your tree hails from a more humid clime, it's likely been spoiled for generations.
Published Study overturns conventional wisdom about wild turkey nesting survival
(via sciencedaily.com) Original source A new study finds that precipitation levels during nesting season are not related to reproductive success for wild turkeys, which runs counter to the conventional wisdom regarding the role that rainfall plays in wild turkey nesting success. The findings shed new light on how climate change may affect wild turkey populations.
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.
Published Why the long face? Scientists solve a major puzzle in mammal skull shape evolution
(via sciencedaily.com) Original source Horses have developed long faces simply 'because they can,' a team of evolutionary biologists say. In a major review of how mammalian heads evolve, scientists found that adaptations to feeding explain why large species of mammals often have much longer faces compared to smaller closely related species -- a pattern referred to as Craniofacial Evolutionary Allometry (CREA).
Published Migratory bats can detect Earth's magnetic field
(via sciencedaily.com) Original source Pipistrelle bats have a magnetic compass and calibrate it at sunset, according to a new study. An international team of researchers has used behavioral experiments to show that two different components of the Earth's magnetic field influence the orientation of these animals. Like birds, they seem to be sensitive to magnetic inclination.
Published In a new light -- new approach overcomes long-standing limitations in optics
(via sciencedaily.com) Original source When you look up at the sky and see clouds of wondrous shapes, or struggle to peer through dense, hazy fog, you're seeing the results of 'Mie scattering', which is what happens with light interacts with particles of a certain size. There is a growing body of research that aims to manipulate this phenomenon and make possible an array of exciting technologies. Researchers have now developed a new means of manipulating Mie scattering from nanostructures.
Published Extremely rare bird captured on film
(via sciencedaily.com) Original source A striking and extremely rare half-female, half-male bird has been spotted by a zoologist.
Published Chance twists ordered carbon nanotubes into 'tornado films'
(via sciencedaily.com) Original source Scientists have developed two new methods to create ordered carbon nanotube films with either a left- or right-handed chiral pattern.
Published Conjoined 'racetracks' make new optical device possible
(via sciencedaily.com) Original source Kerry Vahala and collaborators from UC Santa Barbara have found a unique solution to an optics problem.
Published Hybrid device significantly improves existing, ubiquitous laser technology
(via sciencedaily.com) Original source Researchers have developed a chip-scale laser source that enhances the performance of semiconductor lasers while enabling the generation of shorter wavelengths. This pioneering work represents a significant advance in the field of photonics, with implications for telecommunications, metrology, and other high-precision applications.
Published First observation of structures resulting from 3D domain swapping in antibody light chains
(via sciencedaily.com) Original source Antibodies hold promise as therapeutic agents. However, their tendency to aggregate poses significant challenges to drug development. In a groundbreaking study, researchers now provide novel insights into the structure formed due to 3D domain swapping of the antibody light chain, the part of the antibody contributing to antigen binding. Their findings are expected to lead to improvements in antibody quality and the development of novel drugs.
