Published Computer vision researcher develops privacy software for surveillance videos
(via sciencedaily.com) Original source Computer vision can be a valuable tool for anyone tasked with analyzing hours of footage because it can speed up the process of identifying individuals. For example, law enforcement may use it to perform a search for individuals with a simple query, such as 'Locate anyone wearing a red scarf over the past 48 hours.'
Published Artificial intelligence helps scientists engineer plants to fight climate change
(via sciencedaily.com) Original source Scientists are using artificial intelligence software to analyze plant root systems, laying out a protocol that can be applied to gather data on crop and model plant phenotypes (physical characteristics) more efficiently and with equal or greater accuracy than existing methods.
Published Scientists tune the entanglement structure in an array of qubits
(via sciencedaily.com) Original source A new technique can generate batches of certain entangled states in a quantum processor. This advance could help scientists study the fundamental quantum property of entanglement and enable them to build larger and more complex quantum processors.
Published Artificial intelligence can develop treatments to prevent 'superbugs'
(via sciencedaily.com) Original source Cleveland Clinic researchers developed an artficial intelligence (AI) model that can determine the best combination and timeline to use when prescribing drugs to treat a bacterial infection, based solely on how quickly the bacteria grow given certain perturbations. PNAS recently published their findings.
Published These giant, prehistoric salmon had tusk-like teeth
(via sciencedaily.com) Original source Oncorhynchus rastrosus, a giant species of salmon that lived in the North American Pacific Northwest a few million years ago, sported a pair of front teeth that projected out from the sides of its mouth like tusks, according to a new study.
Published Why can't robots outrun animals?
(via sciencedaily.com) Original source Robotics engineers have worked for decades and invested many millions of research dollars in attempts to create a robot that can walk or run as well as an animal. And yet, it remains the case that many animals are capable of feats that would be impossible for robots that exist today.
Published Computer game in school made students better at detecting fake news
(via sciencedaily.com) Original source A computer game helped upper secondary school students become better at distinguishing between reliable and misleading news.
Published Holographic displays offer a glimpse into an immersive future
(via sciencedaily.com) Original source Researchers have invented a new optical element that brings us one step closer to mixing the real and virtual worlds in an ordinary pair of eyeglasses using high-definition 3D holographic images.
Published Researchers find oldest undisputed evidence of Earth's magnetic field
(via sciencedaily.com) Original source A new study has recovered a 3.7-billion-year-old record of Earth's magnetic field, and found that it appears remarkably similar to the field surrounding Earth today.
Published Opening up the potential of thin-film electronics for flexible chip design
(via sciencedaily.com) Original source The mass production of conventional silicon chips relies on a successful business model with large 'semiconductor fabrication plants' or 'foundries'. New research by shows that this 'foundry' model can also be applied to the field of flexible, thin-film electronics.
Published Bioluminescence first evolved in animals at least 540 million years ago
(via sciencedaily.com) Original source Bioluminescence first evolved in animals at least 540 million years ago in a group of marine invertebrates called octocorals, according to the results of a new study. The study focuses on an ancient group of marine invertebrates that includes soft corals, pushes back the previous oldest dated example of trait by nearly 300 million years.
Published This tiny chip can safeguard user data while enabling efficient computing on a smartphone
(via sciencedaily.com) Original source A new chip can efficiently accelerate machine-learning workloads on edge devices like smartphones while protecting sensitive user data from two common types of attacks -- side-channel attacks and bus-probing attacks.
Published Super Mario hackers' tricks could protect software from bugs
(via sciencedaily.com) Original source Video gamers who exploit glitches in games can help experts better understand buggy software, students suggest.
Published Fossil frogs share their skincare secrets
(via sciencedaily.com) Original source Palaeontologists have solved a hundred-year-old mystery of how some fossil frogs preserve their fleshy parts -- it's all down to their skin. Palaeontologists studied 45-million-year-old fossil frogs from the Geiseltal site in central Germany. Remarkably, the fossils show full body outlines of the soft tissues. The team discovered that the excellent condition of the fossil frogs is due to preservation of ancient skin remnants.
Published 2D materials rotate light polarization
(via sciencedaily.com) Original source Physicists have shown that ultra-thin two-dimensional materials such as tungsten diselenide can rotate the polarization of visible light by several degrees at certain wavelengths under small magnetic fields suitable for use on chips.
Published Accelerating the discovery of new materials via the ion-exchange method
(via sciencedaily.com) Original source Researchers have unveiled a new means of predicting how to synthesize new materials via the ion-exchange. Based on computer simulations, the method significantly reduces the time and energy required to explore for inorganic materials.
Published Teaching a computer to type like a human
(via sciencedaily.com) Original source A new typing model simulates the typing process instead of just predicting words.
Published Skyrmions move at record speeds: A step towards the computing of the future
(via sciencedaily.com) Original source Scientists have discovered that the magnetic nanobubbles known as skyrmions can be moved by electrical currents, attaining record speeds up to 900 m/s. Anticipated as future bits in computer memory, these nanobubbles offer enhanced avenues for information processing in electronic devices. Their tiny size provides great computing and information storage capacity, as well as low energy consumption. Until now, these nanobubbles moved no faster than 100 m/s, which is too slow for computing applications. However, thanks to the use of an antiferromagnetic material as medium, the scientists successfully had the skyrmions move 10 times faster than previously observed. These results offer new prospects for developing higher-performance and less energy-intensive computing devices.
Published How 3D printers can give robots a soft touch
(via sciencedaily.com) Original source Soft skin coverings and touch sensors have emerged as a promising feature for robots that are both safer and more intuitive for human interaction, but they are expensive and difficult to make. A recent study demonstrates that soft skin pads doubling as sensors made from thermoplastic urethane can be efficiently manufactured using 3D printers.
Published First evidence of human occupation in lava tube cave in Saudi Arabia
(via sciencedaily.com) Original source New research has highlighted an area in Arabia that once acted as a key point for cultural exchanges and trades amongst ancient people -- and it all took place in vast caves and lava tubes that have remained largely untapped reservoirs of archaeological abundance in Arabia. Through meticulous excavation and analysis, the international team uncovered a wealth of evidence at Umm Jirsan, spanning from the Neolithic to the Chalcolithic/Bronze Age periods (~10,000-3,500 years ago).
