Published Powering the quantum revolution: Quantum engines on the horizon
(via sciencedaily.com) Original source Scientists unveil exciting possibilities for the development of highly efficient quantum devices.
Published New qubit circuit enables quantum operations with higher accuracy
(via sciencedaily.com) Researchers have developed a novel superconducting qubit architecture that can perform operations between qubits with much higher accuracy than scientists have yet been able to achieve. This architecture, which utilizes a relatively new type of superconducting qubit called fluxonium, is scalable and could be used to someday build a large-scale quantum computer.
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 Pollen analysis suggests peopling of Siberia and Europe by modern humans occurred during a major Pleistocene warming spell
(via sciencedaily.com) Original source A new study appearing in Science Advances compares Pleistocene vegetation communities around Lake Baikal in Siberia, Russia, to the oldest archeological traces of Homo sapiens in the region. The researchers use the 'remarkable evidence' to tell a compelling story from 45,000-50,000 years ago with new detail: how the first humans migrated across Europe and Asia.
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.
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.
Published New study reveals a long history of violence in ancient hunter-gatherer societies
(via sciencedaily.com) Original source Violence was a consistent part of life among ancient communities of hunter-gatherers, according to a new study that looked for signs of trauma on 10,000-year-old skeletal remains from burial sites in northern Chile.
Published Scientists successfully maneuver robot through living lung tissue
(via sciencedaily.com) Scientists have shown that their steerable lung robot can autonomously maneuver the intricacies of the lung, while avoiding important lung structures.
Published 'Garbatrage' spins e-waste into prototyping gold
(via sciencedaily.com) Building on work in human-computer interaction that aims to incorporate sustainability and reuse into the field, researchers introduce 'garbatrage,' a framework for prototype builders centered around repurposing underused devices.
Published Let it flow: Recreating water flow for virtual reality
(via sciencedaily.com) A research team has harnessed the power of deep reinforcement learning to replicate the flow of water when disturbed. The replication allowed for recreating water flow in real time based on only a small amount of data, opening up the possibility for virtual reality interactions involving water.
Published Slow growth in crocodile ancestors pre-dated their semi-aquatic lifestyle
(via sciencedaily.com) Original source A groundbreaking study is reshaping our understanding of crocodile evolution by pinpointing the onset of slow growth rates to the Late Triassic period, much earlier than the previously assumed Early Jurassic timeline. The research highlights newly discovered fossil crocodile ancestors (known as crocodylomorphs) that exhibited slow growth rates, similar to modern-day crocodilians. Intriguingly, these early crocodylomorphs were not the lethargic, semi-aquatic creatures we are familiar with today; they were small, active, and fully terrestrial. The study also suggests that this slow-growth strategy was not a mere evolutionary quirk but a survival mechanism, as only the slow-growing crocodylomorphs managed to survive the End-Triassic mass extinction. This stands in stark contrast to the fast-growing dinosaurs of the same era, setting the stage for the divergent evolutionary paths that would later define their modern descendants.
Published Cloud services without servers: What's behind it
(via sciencedaily.com) A new generation of cloud services is on the rise. It is based on the paradigm of 'serverless computing'. A recent article deals with the history, status and potential of serverless computing.
Published Prehistoric fish fills 100 million year gap in evolution of the skull
(via sciencedaily.com) Original source X-rays of an ancient jawless fish shows earliest-known example of internal cartilage skull, unlike that of any other known vertebrate.
Published Combustion powers bug-sized robots to leap, lift and race
(via sciencedaily.com) Researchers combined soft microactuators with high-energy-density chemical fuel to create an insect-scale quadrupedal robot that is powered by combustion and can outrace, outlift, outflex and outleap its electric-driven competitors.
Published Engineers grow full wafers of high-performing 2D semiconductor that integrates with state-of-the-art chips
(via sciencedaily.com) Researchers have grown a high-performing 2D semiconductor to a full-size, industrial-scale wafer. In addition, the semiconductor material, indium selenide (InSe), can be deposited at temperatures low enough to integrate with a silicon chip.
Published Scientists develop method to detect deadly infectious diseases
(via sciencedaily.com) Researchers have developed a way of detecting the early onset of deadly infectious diseases using a test so ultrasensitive that it could someday revolutionize medical approaches to epidemics. The test is an electronic sensor contained within a computer chip. It employs nanoballs -- microscopic spherical clumps made of tinier particles of genetic material -- and combines that technology with advanced electronics.
Published RNA for the first time recovered from an extinct species
(via sciencedaily.com) Original source A new study shows the isolation and sequencing of more than a century-old RNA molecules from a Tasmanian tiger specimen preserved at room temperature in a museum collection. This resulted in the reconstruction of skin and skeletal muscle transcriptomes from an extinct species for the first time. The researchers note that their findings have relevant implications for international efforts to resurrect extinct species, including both the Tasmanian tiger and the woolly mammoth, as well as for studying pandemic RNA viruses.
Published AI-driven tool makes it easy to personalize 3D-printable models
(via sciencedaily.com) With Style2Fab, makers can rapidly customize models of 3D-printable objects, such as assistive devices, without hampering their functionality.
