Published 'Lost' birds list will aid in protecting species
(via sciencedaily.com) Original source A group of scientists has released the first comprehensive list of birds that haven't been documented with sound or video in more than a decade.
Published Tiny New Zealand bird delivers a lesson in birdsong evolution
(via sciencedaily.com) Original source Scientists are rethinking the evolution of vocal learning in birds. New Zealand's smallest bird, the rifleman or titipounamu, may have a rudimentary version of the talent possessed by parrots, hummingbirds and songbirds.
Published New dart launcher may be better way to inject animals with drugs
(via sciencedaily.com) Original source A new type of dart launcher has been developed as a safer and more cost-effective alternative to firearms or air guns to inject animals with drugs or tracking chips.
Published The scary, yet promising world of phages, the pathogen's pathogen
(via sciencedaily.com) Original source Researchers are unlocking the mystery of how bacteria harness viruses to wipe out the competition. The answers could help spur the development of alternatives to antibiotics.
Published Outdoor recreation noise affects wildlife behavior and habitat use, study finds
(via sciencedaily.com) Original source We may go to the woods seeking peace and quiet, but are we taking our noise with us? A recent study indicates that the answer is yes -- and that this noise can trigger a fear response, as if escaping from predators. This new science calls into question whether otherwise high-quality habitat truly provides refugia for wildlife when recreationists are present and underscores the challenges land managers face in balancing outdoor recreational opportunities with wildlife conservation.
Published A 'liquid battery' advance
(via sciencedaily.com) Original source A team aims to improve options for renewable energy storage through work on an emerging technology -- liquids for hydrogen storage.
Published Humans are the elephant in the room where conservation is debated
(via sciencedaily.com) Original source Studies working to map conservation historically have left humans out of the equation. This study proposes ways to build in the outsized footprint created by people in wild places.
Published Specialist and migratory birds at greater risk under climate change
(via sciencedaily.com) Original source Following decades of decline, even fewer birds will darken North American skies by the end of the century, according to a new analysis. The study examines the long-term effects of climate change on the abundance and diversity of bird groups across the continent as a whole while accounting for additional factors that put birds at risk.
Published Algae offer real potential as a renewable electricity source
(via sciencedaily.com) Original source The need to transition away from fossil fuels to more sustainable energy production is critical. That's why a team of researchers is looking at a potential power source that not only produces no carbon emissions but removes carbon as it works: algae.
Published Semiconductor doping and electronic devices: Heating gallium nitride and magnesium forms superlattice
(via sciencedaily.com) Original source A study revealed that a simple thermal reaction of gallium nitride with metallic magnesium results in the formation of a distinctive superlattice structure. This represents the first time researchers have identified the insertion of 2D metal layers into a bulk semiconductor. By carefully observing materials through various cutting-edge characterization techniques, the researchers uncovered new insights into the process of semiconductor doping and elastic strain engineering.
Published Lazy predator: A new species of mountain pitviper from China
(via sciencedaily.com) Original source Researchers have discovered a new species of medium-sized venomous snake in Yunnan, China. Ovophis jenkinsi is dark brownish-grey in color with trapezoidal patches on its back. It is endemic to China's Yingjiang County and is not difficult to find in the wild. In the future, researchers plan to collect more information about this new species, including its appearance, distribution, and habits.
Published Two can play that game: juvenile dolphins who play together are more successful as adults
(via sciencedaily.com) Original source Juvenile social play predicts adult reproductive success in male bottlenose dolphins, a new study has found.
Published Elephants have names for each other like people do, new study shows
(via sciencedaily.com) Original source Wild African elephants address each other with name-like calls, a rare ability among nonhuman animals, according to a new study. Researchers used machine learning to confirm that elephant calls contained a name-like component identifying the intended recipient, a behavior they suspected based on observation. The study suggests elephants do not imitate the receiver's call to address one another but instead use arbitrary vocal labels like humans.
Published Discovery highlights 'critical oversight' in perceived security of wireless networks
(via sciencedaily.com) Original source A research team has uncovered an eavesdropping security vulnerability in high-frequency and high-speed wireless backhaul links, widely employed in critical applications such as 5G wireless cell phone signals and low-latency financial trading on Wall Street.
Published Fish out of water: How killifish embryos adapted their development
(via sciencedaily.com) Original source The annual killifish lives in regions with extreme drought. A research group now reports that the early embryogenesis of killifish diverges from that of other species. Unlike other fish, their body structure is not predetermined from the outset. This could enable the species to survive dry periods unscathed.
Published Fish in schools have an easier time swimming in rough waters
(via sciencedaily.com) Original source Swimming through turbulent water is easier for schooling fish compared to solitary swimmers, according to a new study.
Published US public opinion on social media is warming to nuclear energy, but concerns remain
(via sciencedaily.com) Original source The U.S. public displays more positive than negative sentiment toward nuclear energy but concerns remain about waste, cost and safety, according to an analysis of 300,000 posts on social media.
Published Flapping frequency of birds, insects, bats and whales described by universal equation
(via sciencedaily.com) Original source A single universal equation can closely approximate the frequency of wingbeats and fin strokes made by birds, insects, bats and whales, despite their different body sizes and wing shapes, researchers report in a new study.
Published Fishy mystery of marine reptile solved
(via sciencedaily.com) Original source The identity of a prehistoric marine reptile has finally been revealed after experts discovered that some of its remains actually belonged to fish.
Published Early summer fishing can have an evolutionary impact, resulting in smaller salmon
(via sciencedaily.com) Original source A new genetic study found that heavy fishing in the early part of the fishing season may result in younger and smaller Atlantic salmon. This information can help to conserve large fish essential for the diversity and viability of salmon populations.
