Published Deep neural networks don't see the world the way we do
(via sciencedaily.com) Original source Computational models of hearing and vision can build up their own idiosyncratic 'invariances' -- meaning they respond the same way to stimuli with very different features, according to scientists.
Published New organ-on-a-chip model of human synovium could accelerate development of treatments for arthritis
(via sciencedaily.com) Original source The synovium is a membrane-like structure that lines the knee joint and helps to keep the joint happy and healthy, mainly by producing and maintaining synovial fluid. Inflammation of this tissue is implicated in the onset and progression of arthritic diseases such as rheumatoid and osteoarthritis. Therefore, treatments that target the synovium are promising in treating these diseases. However, we need better models in the laboratory that allow us to find and test new treatments. We have developed an organ-on-a-chip based model of the human synovium, and its associated vasculature, to address this need.
Published Extraordinary fossil find reveals details about the weight and diet of extinct saber-toothed marsupial
(via sciencedaily.com) Original source A 13-million-year-old saber-toothed marsupial skeleton discovered during paleontological explorations in Colombia is the most complete specimen recovered in the region.
Published A step towards AI-based precision medicine
(via sciencedaily.com) Original source Artificial intelligence, AI, which finds patterns in complex biological data could eventually contribute to the development of individually tailored healthcare. Researchers have developed an AI-based method applicable to various medical and biological issues. Their models can for instance accurately estimate people's chronological age and determine whether they have been smokers or not.
Published Race to find world's oldest mammal fossils led to mud-slinging
(via sciencedaily.com) Original source The hunt for the world’s most ancient mammals descended into academic warfare in the seventies, researchers have discovered.
Published What is the impact of predictive AI in the health care setting?
(via sciencedaily.com) Original source Models built on machine learning in health care can be victims of their own success, according to researchers. Their study assessed the impact of implementing predictive models on the subsequent performance of those and other models.
Published AI language models could help diagnose schizophrenia
(via sciencedaily.com) Original source Scientists have developed new tools, based on AI language models, that can characterize subtle signatures in the speech of patients diagnosed with schizophrenia.
Published Researchers create a neural network for genomics -- one that explains how it achieves accurate predictions
(via sciencedaily.com) Original source A team of computer scientists has created a neural network that can explain how it reaches its predictions. The work reveals what accounts for the functionality of neural networks--the engines that drive artificial intelligence and machine learning--thereby illuminating a process that has largely been concealed from users.
Published Survival of the newest: the mammals that survive mass extinctions aren't as 'boring' as scientists thought
(via sciencedaily.com) Original source For decades, scientists have assumed that mammals and their relatives that survived challenging times (like those during mass extinctions) made it because they were generalists that were able to eat just about anything and adapt to whatever life threw at them. A new study into the mammal family tree through multiple mass extinctions revealed that the species that survived aren't as generic as scientists had thought: instead, having new and different traits can be the key to succeeding in the aftermath of a catastrophe.
Published Machine learning used to probe the building blocks of shapes
(via sciencedaily.com) Original source Applying machine learning to find the properties of atomic pieces of geometry shows how AI has the power to accelerate discoveries in maths.
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 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 Groundbreaking mathematical proof: New insights into typhoon dynamics unveiled
(via sciencedaily.com) Original source A research team has provided irrefutable proof that certain spherical vortices exist in a stable state.
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 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 New research reveals extreme heat likely to wipe out humans and mammals in the distant future
(via sciencedaily.com) Original source A new study shows unprecedented heat is likely to lead to the next mass extinction, akin to when the dinosaurs died out, eliminating nearly all mammals in some 250 million years time.
Published Drug discovery on an unprecedented scale
(via sciencedaily.com) Boosting virtual screening with machine learning allowed for a 10-fold time reduction in the processing of 1.56 billion drug-like molecules. Researchers teamed up with industry and supercomputers to carry out one of the world's largest virtual drug screens.
Published Researchers' analysis of perching birds points to new answers in evolutionary diversification
(via sciencedaily.com) Original source When Charles Darwin traveled to the Galapagos Islands almost 200 years ago as a gentleman naturalist, he used the power of observation to develop his theory that species evolve over time.
Published AI helps bring clarity to LASIK patients facing cataract surgery
(via sciencedaily.com) Scientists develop computer models of patients' eyes to identify the ideal intraocular lenses and visual simulators for patients to experience how they will see with them.
Published Dinosaur feathers reveal traces of ancient proteins
(via sciencedaily.com) Original source Palaeontologists have discovered X-ray evidence of proteins in fossil feathers that sheds new light on feather evolution.
