Published Newborn baby inspires sensor design that simulates human touch
(via sciencedaily.com) Original source As we move into a world where human-machine interactions are becoming more prominent, pressure sensors that are able to analyze and simulate human touch are likely to grow in demand.
Published Self-driving cars lack social intelligence in traffic
(via sciencedaily.com) Original source Self-driving cars fall short when it comes to understanding the social codes in traffic that let human drivers decide whether to give way or drive on, according to new research.
Published New tool may help spot 'invisible' brain damage in college athletes
(via sciencedaily.com) Original source An artificial intelligence computer program that processes magnetic resonance imaging (MRI) can accurately identify changes in brain structure that result from repeated head injury, a new study in student athletes shows. These variations have not been captured by other traditional medical images such as computerized tomography (CT) scans. The new technology, researchers say, may help design new diagnostic tools to better understand subtle brain injuries that accumulate over time.
Published Robot centipedes go for a walk
(via sciencedaily.com) Original source Researchers show how their multilegged walking robot can be steered by inducing a dynamic instability. By making the couplings between segments more flexible, the robot changes from walking straight to moving in a curved path. This work can lead to more energy-efficient and reliable robotic navigation of terrain.
Published Super low-cost smartphone attachment brings blood pressure monitoring to your fingertips
(via sciencedaily.com) Original source Engineers have developed a simple 3D-printed attachment that clips over a smartphone's camera and flash to measure blood pressure at the user's fingertip. The clip works with a custom smartphone app and currently costs about 80 cents to make. Researchers say it could help make regular blood pressure monitoring easy, affordable and accessible to people in resource-poor communities.
Published Making the structure of 'fire ice' with nanoparticles
(via sciencedaily.com) Original source Cage structures made with nanoparticles could be a route toward making organized nanostructures with mixed materials, and researchers have shown how to achieve this through computer simulations.
Published Quantum scientists accurately measure power levels one trillion times lower than usual
(via sciencedaily.com) Original source Scientists have developed a nanodevice that can measure the absolute power of microwave radiation down to the femtowatt level at ultra-low temperatures -- a scale trillion times lower than routinely used in verifiable power measurements. The device has the potential to significantly advance microwave measurements in quantum technology.
Published Breakthrough in computer chip energy efficiency could cut data center electricity use
(via sciencedaily.com) Original source Researchers have made a breakthrough toward reducing the energy consumption of the photonic chips used in data centers and supercomputers.
Published Effects of crypto mining on Texas power grid
(via sciencedaily.com) Original source Scientists are working to understand how cryptocurrency mining impacts the power grid and how to use this information for further research, education and policymaking.
Published Earliest evidence of wine consumption in the Americas found in Caribbean
(via sciencedaily.com) Original source Scientists have found what they believe to be the earliest known evidence of wine drinking in the Americas, inside ceramic artefacts recovered from a small Caribbean island.
Published Artificial intelligence catalyzes gene activation research and uncovers rare DNA sequences
(via sciencedaily.com) Original source Biologists have used machine learning, a type of AI, to identify 'synthetic extreme' DNA sequences with specifically designed functions in gene activation. They tested 50 million DNA sequences and found synthetic DNA sequences with activities that could be useful in biotechnology and medicine.
Published Ancient climate change solves mystery of vanished South African lakes
(via sciencedaily.com) Original source New evidence for the presence of ancient lakes in some of the most arid regions of South Africa suggests that Stone Age humans may have been more widespread across the continent than previously thought.
Published Oldest architectural plans detail mysterious desert mega structures
(via sciencedaily.com) Original source Researchers have identified engravings in Jordan and Saudi Arabia as the oldest known scaled building plans in human history.
Published Humanity's earliest recorded kiss occurred in Mesopotamia 4,500 years ago
(via sciencedaily.com) Original source Written sources from Mesopotamia suggest that kissing in relation to sex was practiced by the peoples of the ancient Middle East 4,500 years ago.
Published Wiring up quantum circuits with light
(via sciencedaily.com) Original source The number of qubits in superconducting quantum computers has risen rapidly during the last years, but further growth is limited by the need for ultra-cold operating temperatures. Connecting several smaller processors could create larger, more computationally powerful quantum computers -- however doing so poses new challenges. Researchers have now demonstrated quantum entanglement between optical and microwave photons that could lay the foundation for such a future quantum network.
Published New wireless system for greater 5G access
(via sciencedaily.com) Original source A new paper on wireless connectivity introduces a new technique for increasing access to the 5G-and-beyond millimeter wave (mmWave) network.
Published A better way to study ocean currents
(via sciencedaily.com) Original source Computer scientists and oceanographers developed a machine-learning model that generates more accurate predictions about the velocities of ocean currents. The model could help make more precise weather forecasts or effectively predict how oil will spread after a spill.
Published Curved spacetime in a quantum simulator
(via sciencedaily.com) Original source The connection between quantum physics and the theory of relativity is extremely hard to study. But now, scientists have set up a model system, which can help: Quantum particles can be tuned in such a way that the results can be translated into information about other systems, which are much harder to observe. This kind of 'quantum simulator' works very well and can lead to new insights about the nature of relativity and quantum physics.
Published South Africa's desert-like interior may have been more inviting to our human ancestors
(via sciencedaily.com) Original source Lining the Cape of South Africa and its southern coast are long chains of caves that nearly 200,000 years ago were surrounded by a lush landscape and plentiful food.
Published Can't find your phone? There's a robot for that
(via sciencedaily.com) Original source Engineers have discovered a new way to program robots to help people with dementia locate medicine, glasses, phones and other objects they need but have lost.
