Published Birders and AI push bird conservation to the next level
(via sciencedaily.com) Original source Big data and artificial intelligence (AI) are being used to model hidden patterns in nature, not just for one bird species, but for entire ecological communities across continents. And the models follow each species’ full annual life cycle, from breeding to fall migration to non-breeding grounds, and back north again during spring migration.
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 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 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 Scientists identify evolutionary gateway helping pneumonia bacteria become resistant to antibiotics
(via sciencedaily.com) Original source An evolutionary gateway which helps pneumonia cells become resistant to antibiotics has been discovered.
Published Genetics of attraction: Mate choice in fruit flies
(via sciencedaily.com) Original source Genetic quality or genetic compatibility? What do female fruit flies prioritize when mating? Researchers show that both factors are important at different stages of the reproductive process and that females use targeted strategies to optimize the fitness of their offspring.
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 Insights into early snake evolution through brain analysis
(via sciencedaily.com) Original source Recent study sheds new light on the enigmatic early evolution of snakes by examining an unexpected source: their brains. The results emphasize the significance of studying both the soft parts of animals’ bodies and their bones for understanding how animals evolved.
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 Did animal evolution begin with a predatory lifestyle?
(via sciencedaily.com) Original source Surprising findings on the development of sea anemones suggest that a predatory lifestyle molded their evolution and had a significant impact on the origin of their nervous system. The researchers were able to show that the young life stages (larvae) of the small sea anemone Aiptasia actively feed on living prey and are not dependent on algae. To capture its prey, the anemone larvae use specialized stinging cells and a simple neuronal network.
Published A turtle time capsule: DNA found in ancient shell
(via sciencedaily.com) Original source Paleontologists discover possible DNA remains in fossil turtle that lived 6 million years ago in Panama, where continents collide.
Published Sperm swimming is caused by the same patterns that are believed to dictate zebra stripes
(via sciencedaily.com) Original source Patterns of chemical interactions are thought to create patterns in nature such as stripes and spots. This new study shows that the mathematical basis of these patterns also governs how sperm tail moves.
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 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 Study shows birds that have evolved greater complexity are less biodiverse
(via sciencedaily.com) Original source Research shows that birds with more complex skeletons are more specialized and so are less species rich.
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.
Published AI increases precision in plant observation
(via sciencedaily.com) Original source Artificial intelligence (AI) can help plant scientists collect and analyze unprecedented volumes of data, which would not be possible using conventional methods. Researchers have now used big data, machine learning and field observations in the university's experimental garden to show how plants respond to changes in the environment.
Published Efficient training for artificial intelligence
(via sciencedaily.com) New physics-based self-learning machines could replace the current artificial neural networks and save energy.
