Published Ruffed grouse population more resilient than expected, genetic study finds
(via sciencedaily.com) Original source Despite decades of decline, a genetic analysis of ruffed grouse reveals that Pennsylvania's state bird harbors more genetic diversity and connectivity than expected. The findings suggest that the iconic game bird could be maintained in persistent numbers if appropriate protections are implemented.
Published Bird species changing faster than expected in protected areas
(via sciencedaily.com) Original source A recent study has found that bird communities inside and outside protected areas are beginning to resemble each other as a result of climate change. In both areas, southern species increase in abundance, while northern species decrease.
Published Could future AI crave a favorite food?
(via sciencedaily.com) Original source Can artificial intelligence (AI) get hungry? Develop a taste for certain foods? Not yet, but a team of researchers is developing a novel electronic tongue that mimics how taste influences what we eat based on both needs and wants, providing a possible blueprint for AI that processes information more like a human being.
Published These robots helped explain how insects evolved two distinct strategies for flight
(via sciencedaily.com) Original source Robots helped achieve a major breakthrough in our understanding of how insect flight evolved. The study is a result of a six-year long collaboration between roboticists and biophysicists.
Published Honeybees are more selective in their choices for nutrition than previously thought
(via sciencedaily.com) Original source An international research group examined which plants honeybees favor when collecting nectar and pollen. The choices honeybees make have an impact on their health and also on humans, as honeybees pollinate important crop plants.
Published Insect cyborgs: Towards precision movement
(via sciencedaily.com) Original source Insect cyborgs may sound like something straight out of the movies, but hybrid insect computer robots, as they are scientifically called, could pioneer a new future for robotics. It involves using electrical stimuli to control an insect’s movement. Now, an international research group has conducted a study on the relationship between electrical stimulation in stick insects' leg muscles and the resulting torque (the twisting force that causes the leg to move).
Published Unique voice print in parrots
(via sciencedaily.com) Original source Individual voice could help birds be recognized in a flock, no matter what they say.
Published Power of rhythm as a design element in evolution and robotics
(via sciencedaily.com) Original source As the internet quickly fills with viral videos of futuristic robots darting and racing around like the animals they’re built to mimic, researchers say that there’s an element of their movement’s programming that should not be overlooked: rhythm.
Published Instant evolution: AI designs new robot from scratch in seconds
(via sciencedaily.com) Original source Researchers developed the first AI to date that can intelligently design robots from scratch by compressing billions of years of evolution into mere seconds. It's not only fast but also runs on a lightweight computer and designs wholly novel structures from scratch — without human-labeled, bias-filled datasets.
Published To prepare for next pandemic, researchers tackle bird flu
(via sciencedaily.com) Original source Researchers have developed an improved way to test potential vaccines against bird flu.
Published Genome study reveals 30 years of Darwin's finch evolution
(via sciencedaily.com) Original source An international team of researchers has released a landmark study on contemporary evolutionary change in natural populations. Their study uses one of the largest genomic datasets ever produced for animals in their natural environment, comprising nearly 4,000 Darwin's finches. The study has revealed the genetic basis of adaptation in this iconic group.
Published Explosion in fish biodiversity due to genetic recycling
(via sciencedaily.com) Original source The rapid formation of 500 different species of fish in a single lake, each with specialized ecological roles, resulted from a small but genetically diverse hybrid population.
Published Timing plant evolution with a fast-ticking epigenetic clock
(via sciencedaily.com) Original source Recent discoveries in the field of epigenetics, the study of inheritance of traits that occur without changing the DNA sequence, have shown that chronological age in mammals correlates with epigenetic changes that accumulate during the lifetime of an individual. In humans, this observation has led to the development of epigenetic clocks, which are now extensively used as biomarkers of aging. While these clocks work accurately from birth until death, they are set back to zero in each new generation. Now, an international team shows that epigenetic clocks not only exist in plants, but that these clocks keep ticking accurately over many generations.
Published Wild Asian elephants display unique puzzle solving skills
(via sciencedaily.com) Original source A new study has documented the abilities of individual wild Asian elephants to access food by solving puzzles that unlocked storage boxes. It is the first research study to show that individual wild elephants have different willingness and abilities to problem solve in order to get food.
Published Boo to a goose -- new animal behaviour tech aims to save wildlife
(via sciencedaily.com) Original source Facial recognition software used to study the social behavior of individual Greylag Geese in Europe will soon be used to monitor one of the rarest geese in the world, the Cape Barren Goose in South Australia. The technology was used to assess how each bird responds to images of themselves, other flock mates or partners and researchers say it could be used by other scientists or in citizen science apps around the world to monitor and record endangered wildlife or even to promote the welfare of animals in captivity.
Published Why are killer whales harassing and killing porpoises without eating them?
(via sciencedaily.com) Original source For decades, fish-eating killer whales in the Pacific Northwest have been observed harassing and even killing porpoises without consuming them —- a perplexing behavior that has long intrigued scientists.
Published Unleashing the power of AI to track animal behavior
(via sciencedaily.com) Scientists have created a non-invasive movement tracking method called GlowTrack that uses fluorescent dye markers to train artificial intelligence to capture movement, from a single mouse digit to the human hand. GlowTrack has applications spanning biology, robotics, medicine, and beyond.
Published One-hour training is all you need to control a third robotic arm, study finds
(via sciencedaily.com) A new study has found that people can learn to use supernumerary robotic arms as effectively as working with a partner in just one hour of training.
Published Caribbean parrots thought to be endemic are actually relicts of millennial-scale extinction
(via sciencedaily.com) Original source For the first time, researchers have extracted ancient DNA from Caribbean parrot fossils and archaeological specimens, showing that species thought to be endemic to particular islands were historically more widespread and diverse.
Published Colorful primates don't have better color vision, study finds
(via sciencedaily.com) Original source Primate species with better color vision are not more likely to have red skin or fur coloration, as previously thought.
