Feathered friends can become unlikely helpers for tropical coral reefs facing climate change threat      (via sciencedaily.com)     Original source 

Tropical coral reefs are among our most spectacular ecosystems, yet a rapidly warming planet threatens the future survival of many reefs. However, there may be hope for some tropical reefs in the form of feathered friends. A new study has found that the presence of seabirds on islands adjacent to tropical coral reefs can boost coral growth rates on those reefs by more than double.

Jays jump in while crows hold out for the treat      (via sciencedaily.com)     Original source 

New research has found that two similar species of birds behave very differently around their favorite food when they have company. Biologists compared the behavior of two species of corvids, Eurasian jays and New Caledonian crows, both capable of displaying self-control through delayed gratification. The researchers found that jays will settle for an immediate, less preferred food option when another bird is present, while crows will always hold out for their favorite food, regardless of the social context.

'Friendly' hyenas are more likely to form mobs      (via sciencedaily.com)     Original source 

Research reveals strong social relationships make hyenas more likely to team up against lions, even when there's no obvious benefit.

Artificial intelligence makes gripping more intuitive      (via sciencedaily.com)     Original source 

Artificial hands can be operated via app or with sensors placed in the muscles of the forearm. New research shows: a better understanding of muscle activity patterns in the forearm supports a more intuitive and natural control of artificial limbs. This requires a network of 128 sensors and artificial intelligence based techniques.

Enhanced AI tracks neurons in moving animals      (via sciencedaily.com)     Original source 

Scientists have developed a pioneering new method that uses deep learning and a new technique called 'targeted augmentation' to track neurons in moving and deforming animals.

New study identifies the greatest threat to wildlife across North America and Canada: people      (via sciencedaily.com)     Original source 

A biology student studied more than 600,000 wildlife rehabilitation center records to look at the human impact on wild animals, from lead poisonings to window strikes to vehicle collisions.

Artificial light is luring birds to cities and sometimes to their deaths      (via sciencedaily.com)     Original source 

Scientists used weather radar data to map bird stopover density in the United States and found that artificial light is a top indicator of where birds will land. City lights lure birds into what can be an ecological trap -- with buildings that lead to collisions, less habitat, scarcer food, and more people and cats. The study provides the first continent-wide maps of migration stopover hotspots in the contiguous United States, and knowing these broadscale layover patterns can help in the development of conservation plans.

Tiny electromagnets made of ultra-thin carbon      (via sciencedaily.com)     Original source 

Graphene, that is extremely thin carbon, is considered a true miracle material. An international research team has now added another facet to its diverse properties with new experiments: Experts fired short terahertz pulses at micrometer-sized discs of graphene, which briefly turned these minuscule objects into surprisingly strong magnets. This discovery may prove useful for developing future magnetic switches and storage devices.

Earliest-known fossil mosquito suggests males were bloodsuckers too      (via sciencedaily.com)     Original source 

Researchers have found the earliest-known fossil mosquito in Lower Cretaceous amber from Lebanon. What's more, the well-preserved insects are two males of the same species with piercing mouthparts, suggesting they likely sucked blood. That's noteworthy because, among modern-day mosquitoes, only females are hematophagous, meaning that they use piercing mouthparts to feed on the blood of people and other animals.

Crocodile family tree mapped: New light shed on croc evolution      (via sciencedaily.com)     Original source 

Around 250 million years ago, 700 species of reptiles closely related to the modern-day crocodile roamed the earth, now new research reveals how a complex interplay between climate change, species competition and habitat can help explain why just 23 species of crocodile survive today.

Scientists navigate uncharted waters in fish immunology research      (via sciencedaily.com)     Original source 

Upon infection or immunization, all jawed vertebrate species generate proteins called antibodies that bind and neutralize pathogens. Strong and long-lasting antibody responses in warm-blooded species such as mammals are produced in secondary lymphoid microstructures (SLMs) among which germinal centers (GCs) are the centerpiece. Despite the apparent absence of GCs or similar SLMs in cold-blooded vertebrates (e.g., fish), these species can mount significant antibody responses that can persist for several months. Thus, for decades, the outstanding question has remained as to how and where antibody responses are generated in species that lack GCs or analogous SLM structures.

To help autonomous vehicles make moral decisions, researchers ditch the 'trolley problem'      (via sciencedaily.com)     Original source 

Researchers have developed a new experiment to better understand what people view as moral and immoral decisions related to driving vehicles, with the goal of collecting data to train autonomous vehicles how to make 'good' decisions. The work is designed to capture a more realistic array of moral challenges in traffic than the widely discussed life-and-death scenario inspired by the so-called 'trolley problem.'

Scientists build tiny biological robots from human cells      (via sciencedaily.com)     Original source 

Scientists have created tiny moving biological robots from human tracheal cells that can encourage the growth of neurons across artificial 'wounds' in the lab. Using patients' own cells could permit growth of Anthrobots that assist healing and regeneration in the future with no nead for immune suppression.

Broadband buzz: Periodical cicadas' chorus measured with fiber optic cables      (via sciencedaily.com)     Original source 

Through an emerging technology called distributed fiber optic sensing, cables bringing high-speed internet to American households can be used to detect temperature changes, vibrations, and even sound. And periodical cicadas -- the insects that emerge by the billions every 13 or 17 years and make a racket with their mating calls -- are loud enough to be detected. A new study shows how fiber optic sensing could open new pathways for charting populations of these famously ephemeral bugs.
