Published Genetics provide key to fight crown-of-thorns starfish



Scientists are one step closer to combating coral-destroying crown-of-thorns starfish, following a study into the pest's genetics.
Published Most dangerous areas for whale shark-shipping vessel collisions revealed



Heavily-used shipping lanes that pass through whale shark feeding grounds pose a threat to the species, according to scientists who have revealed areas where the creatures are at the highest risk.
Published Metalens expands Its reach from light to sound



Engineers achieve a wide field-of-hearing acoustic metalens free from aberrations.
Published New viruses that could cause epidemics on the horizon



Suddenly they appear and -- like the SARS-CoV-2 coronavirus -- can trigger major epidemics: Viruses that nobody had on their radar. They are not really new, but they have changed genetically. In particular, the exchange of genetic material between different virus species can lead to the sudden emergence of threatening pathogens with significantly altered characteristics.
Published Island birds more adaptable than previously thought



The researchers found that birds were more evolutionarily similar on smaller, more isolated islands than on larger, less remote places. The team had expected to find that forested areas had more numerous and more varied species of birds compared to farmland areas. But they were surprised to find that the opposite was true: Areas with farms and human settlements had more species of birds and greater diversity than forested areas.
Published US Navy Growler jet noise over Whidbey Island could impact 74,000 people's health



As often as four days a week, Boeing EA-18G Growler electronic attack aircraft based at Naval Air Station Whidbey Island fly loops overhead as pilots practice touch-and-go landings. The noise is immense. New research shows that the noise isn't just disruptive -- it presents a substantial risk to public health.
Published New record holder for smallest dispersers of ingested seeds: Woodlice



Even bugs as small as woodlice can disperse seeds they eat, setting a new record for smallest animal recorded to do so. The discovery underscores the crucial yet often overlooked role that small invertebrates play in ecosystems.
Published Acceptance of animals in urban environments



How do city residents feel about animals in their immediate surroundings? A recent study shows how different the acceptance of various wild animals in urban areas is. Important factors are the places where the animals are found and their level of popularity -- squirrels and ladybugs come out on top here. The results have important implications for urban planning and nature conservation.
Published This sound-suppressing silk can create quiet spaces



Researchers developed a silk fabric, which is barely thicker than a human hair, that can suppress unwanted noise and reduce noise transmission in a large room.
Published Chimps learn and improve tool-using skills even as adults, study finds



Chimpanzees continue to learn and hone their skills well into adulthood, a capacity that might be essential for the evolution of complex and varied tool use, according to a new study.
Published Why getting in touch with our 'gerbil brain' could help machines listen better



Researchers have debunked a 75-year-old theory about how humans determine where sounds are coming from, and it could unlock the secret to creating a next generation of more adaptable and efficient hearing devices ranging from hearing aids to smartphones.
Published DDT pollutants found in deep sea fish off Los Angeles coast



As the region reckons with its toxic history of offshore dumping off the California coast, new findings raise troubling questions about whether the banned pesticide remains a threat to wildlife and human health.
Published In medieval England, leprosy spread between red squirrels and people, genome evidence shows



Evidence from archaeological sites in the medieval English city of Winchester shows that English red squirrels once served as an important host for Mycobacterium leprae strains that caused leprosy in people, researchers report.
Published Artificial intelligence enhances monitoring of threatened marbled murrelet



Artificial intelligence analysis of data gathered by acoustic recording devices is a promising new tool for monitoring the marbled murrelet and other secretive, hard-to-study species.
Published Missing link in species conservation: Pharmacists, chemists could turn tide on plant, animal extinction



As the world faces the loss of a staggering number of species of animals and plants to endangerment and extinction, one scientist has an urgent message: Chemists and pharmacists should be key players in species conservation efforts.
Published Researchers parse oddity of distantly related bats in Solomon Islands that appear identical



A study of body size in leaf-nosed bats of the Solomon Islands has revealed surprising genetic diversity among nearly indistinguishable species on different islands.
Published Protecting endangered monkeys from poachers, habitat loss



The 17 species of red colobus monkey living across Africa, including in the Tai Project field station region, have been singled out by scientists as a priority conservation target. Protection of these monkeys, they assert, can be expected to produce benefits throughout tropical African forests where hunting and climate change have led to dramatic wildlife and habitat loss.
Published Fading lights: Multiple threats to North America's firefly populations



Scientists have applied a data-driven approach to understanding firefly population dynamics on a continental scale. Key findings from this new study indicate that fireflies, part of the beetle order, are sensitive to various environmental factors, from short-term weather conditions to longer climatic trends, including the number of growing-degree days related to temperature accumulations.
Published More plants on the menu of ancient hunter-gatherers



It has long been thought that meat played an important role in the diet of hunter-gatherers before the Neolithic transition. However, due to the scarcity of well-preserved human remains from Paleolithic sites, little information exists about the dietary habits of pre-agricultural human groups. A new study challenges this notion by presenting compelling isotopic evidence of a strong preference for plants among 15,000-year-old hunter-gatherers from Morocco. This is the first time a significant amount of plant consumption has been measured for a pre-agricultural population, shedding new light on the dietary practices of ancient human societies.
Published Florida dolphin found with highly pathogenic avian flu



Report details first-ever finding of highly pathogenic avian influenza virus in North American dolphin.
