Published A touch-responsive fabric armband -- for flexible keyboards, wearable sketchpads
(via sciencedaily.com) Original source It's time to roll up your sleeves for the next advance in wearable technology -- a fabric armband that's actually a touch pad. Researchers say they have devised a way to make playing video games, sketching cartoons and signing documents easier. Their proof-of-concept silk armband turns a person's forearm into a keyboard or sketchpad. The three-layer, touch-responsive material interprets what a user draws or types and converts it into images on a computer.
Published Joyful music could be a game changer for virtual reality headaches
(via sciencedaily.com) Original source Listening to music could reduce the dizziness, nausea and headaches virtual reality users might experience after using digital devices, research suggests. Cybersickness -- a type of motion sickness from virtual reality experiences such as computer games -- significantly reduces when joyful music is part of the immersive experience, the study found. The intensity of the nausea-related symptoms of cybersickness was also found to substantially decrease with both joyful and calming music.
Published Quantum entanglement of photons doubles microscope resolution
(via sciencedaily.com) Original source Using a "spooky" phenomenon of quantum physics, researchers have discovered a way to double the resolution of light microscopes.
Published Researchers discover that the ice cap is teeming with microorganisms
(via sciencedaily.com) Original source Greenlandic ice is teeming with life, both on the surface and underneath. There are microscopic organisms that until recently science had no idea existed. There is even evidence to suggest that the tiny creatures color the ice and make it melt faster.
Published Sensor enables high-fidelity input from everyday objects, human body
(via sciencedaily.com) Original source Couches, tables, sleeves and more can turn into a high-fidelity input device for computers using a new sensing system.
Published Lithography-free photonic chip offers speed and accuracy for artificial intelligence
(via sciencedaily.com) Original source Researchers have created a photonic device that provides programmable on-chip information processing without lithography, offering the speed of photonics augmented by superior accuracy and flexibility for AI applications. Achieving unparalleled control of light, this device consists of spatially distributed optical gain and loss. Lasers cast light directly on a semiconductor wafer, without the need for defined lithographic pathways.
Published Brain activity decoder can reveal stories in people's minds
(via sciencedaily.com) Original source A new AI-based system called a semantic decoder can translate a person's brain activity -- while listening to a story or silently imagining telling a story -- into a continuous stream of text. Unlike other thought decoding systems in development, this system does not require subjects to have surgical implants, making the process noninvasive.
Published Engineers 'grow' atomically thin transistors on top of computer chips
(via sciencedaily.com) Original source A new method enables 2D-material semiconductor transistors to be directly integrated onto a fully fabricated 8-inch silicon wafer, which could enable a new generation of transistor technology, denser device integration, new circuit architectures, and more powerful chips.
Published Male California sea lions are becoming bigger and better fighters as their population rebounds
(via sciencedaily.com) Original source California sea lions have managed to maintain -- and, in the case of males, increase -- their average body size as their population grows and competition for food becomes fiercer. This is in contrast to other marine mammals, whose average body size tends to decrease as their numbers increase. Researchers report that sexual selection was a strong driving force for males to grow bigger and to strengthen muscles in their neck and jaw that help them fight for mates. Both male and female sea lions evaded food shortages by diversifying their diets and, in some cases, foraging further from the shore.
Published Brain circuits for locomotion evolved long before appendages and skeletons
(via sciencedaily.com) Original source Scientists found parallels between the neural circuitry that guides locomotion in sea slugs and in more complex animals like mammals.
Published Robot fish makes splash with motion breakthrough
(via sciencedaily.com) Original source A coil-powered robot fish could make underwater exploration more accessible.
Published How a horse whisperer can help engineers build better robots
(via sciencedaily.com) Original source New research shows us that age-old interactions between people and their horses can teach us something about building robots designed to improve our lives.
Published Ocean ecosystem: Mixotrophic microorganisms play key role
(via sciencedaily.com) Original source Researchers have identified a previously unknown group of bacteria, called UBA868, as key players in the energy cycle of the deep ocean. They are significantly involved in the biogeochemical cycle in the marine layer between 200 and 1000 meters.
Published Jellyfish-like robots could one day clean up the world's oceans
(via sciencedaily.com) Original source Roboticists have developed a jellyfish-inspired underwater robot with which they hope one day to collect waste from the bottom of the ocean. The almost noise-free prototype can trap objects underneath its body without physical contact, thereby enabling safe interactions in delicate environments such as coral reefs. Jellyfish-Bot could become an important tool for environmental remediation.
Published Scientists have full state of a quantum liquid down cold
(via sciencedaily.com) Original source A team of physicists has illuminated certain properties of quantum systems by observing how their fluctuations spread over time. The research offers an intricate understanding of a complex phenomenon that is foundational to quantum computing.
Published Whales stop by Gold Coast bay for day spa fix with full body scrubs
(via sciencedaily.com) Original source A new Griffith University study has found that humpback whales will use sandy, shallow bay areas to 'roll' around in sandy substrates to remove dead skin cells on their return journeys south to cooler waters. Using data and footage collected from the tags, whales were observed performing full and side rolls in up to 49m water depth on the sea floor that was lined with fine sand or rubble.
Published Elephant seals drift off to sleep while diving far below the ocean surface
(via sciencedaily.com) Original source For the first time, scientists have recorded brain activity in a free-ranging, wild marine mammal, revealing the sleep habits of elephant seals during the months they spend at sea. The new findings show that while elephant seals may spend 10 hours a day sleeping on the beach during the breeding season, they average just 2 hours of sleep per day when they are at sea on months-long foraging trips. They sleep for about 10 minutes at a time during deep, 30-minute dives, often spiraling downward while fast asleep, and sometimes lying motionless on the seafloor.
Published Reinforcement learning: From board games to protein design
(via sciencedaily.com) Original source An AI strategy proven adept at board games like Chess and Go, reinforcement learning, has now been adapted for a powerful protein design program. The results show that reinforcement learning can do more than master board games. When trained to solve long-standing puzzles in protein science, the software excelled at creating useful molecules. In one experiment, proteins made with the new approach were found to be more effective at generating useful antibodies in mice than were previous methods. If this method is applied to the right research problems, it likely could accelerate progress in a variety of scientific fields.
Published The climate crisis and biodiversity crisis can't be approached as two separate things
(via sciencedaily.com) Original source Anthropogenic climate change has, together with the intensive use and destruction of natural ecosystems through agriculture, fishing and industry, sparked an unprecedented loss of biodiversity that continues to worsen. In this regard, the climate crisis and biodiversity crisis are often viewed as two separate catastrophes. An international team of researchers calls for adopting a new perspective.
Published Two qudits fully entangled
(via sciencedaily.com) Original source Recently quantum computers started to work with more than just the zeros and ones we know from classical computers. Now a team demonstrates a way to efficiently create entanglement of such high-dimensional systems to enable more powerful calculations.
