Published Environmental toxin PCB found in deep sea trench
(via sciencedaily.com) Original source Researchers on a deep-sea expedition have found PCB in sediment samples from the more than 8,000-meter-deep Atacama Trench in the Pacific Ocean.
Published Less ice, fewer calling seals
(via sciencedaily.com) Original source For several years, a team of researchers used underwater microphones to listen for seals at the edge of the Antarctic. Their initial findings indicate that sea-ice retreat has had significant effects on the animals' behavior: when the ice disappears, areas normally full of vocalizations become very quiet.
Published New approach estimates long-term coastal cliff loss
(via sciencedaily.com) Original source A new method for estimating cliff loss over thousands of years in Del Mar, California, may help reveal some of the long-term drivers of coastal cliff loss in the state.
Published Processing data at the speed of light
(via sciencedaily.com) Original source Scientists have developed an extremely small and fast nano-excitonic transistor.
Published Predictive power of climate models may be masked by volcanoes
(via sciencedaily.com) Original source Simulated volcanic eruptions may be blowing up our ability to predict near-term climate, according to a new study.
Published It's all in the wrist: Energy-efficient robot hand learns how not to drop the ball
(via sciencedaily.com) Original source Researchers have designed a low-cost, energy-efficient robotic hand that can grasp a range of objects -- and not drop them -- using just the movement of its wrist and the feeling in its 'skin'.
Published Study re-evaluates hazards and climate impacts of massive underwater volcanic eruptions
(via sciencedaily.com) Original source Material left on the seafloor by bronze-age underwater volcanic eruptions is helping researchers better understand the size, hazards and climate impact of their parent eruptions, according to new research.
Published Warm liquid spewing from Oregon seafloor comes from Cascadia fault, could offer clues to earthquake hazards
(via sciencedaily.com) Original source Oceanographers discovered warm, chemically distinct liquid shooting up from the seafloor about 50 miles off Newport. They named the unique underwater spring 'Pythia's Oasis.' Observations suggest the spring is sourced from water 2.5 miles beneath the seafloor at the plate boundary, regulating stress on the offshore subduction zone fault.
Published Table tennis brain teaser: Playing against robots makes our brains work harder
(via sciencedaily.com) Original source Brain scans taken during table tennis reveal differences in how we respond to human versus machine opponents.
Published Technology advance paves way to more realistic 3D holograms for virtual reality and more
(via sciencedaily.com) Original source Researchers have developed a new way to create dynamic ultrahigh-density 3D holographic projections. They now describe their new approach, called three-dimensional scattering-assisted dynamic holography (3D-SDH). They show that it can achieve a depth resolution more than three orders of magnitude greater than state-of-the-art methods for multiplane holographic projection.
Published Ice sheets can collapse faster than previously thought possible
(via sciencedaily.com) Original source Ice sheets can retreat up to 600 meters a day during periods of climate warming, 20 times faster than the highest rate of retreat previously measured. An international team of researchers used high-resolution imagery of the seafloor to reveal just how quickly a former ice sheet that extended from Norway retreated at the end of the last Ice Age, about 20,000 years ago.
Published Warming Arctic draws marine predators northwards
(via sciencedaily.com) Original source Marine predators have expanded their ranges into the Arctic waters over the last twenty years, driven by climate change and associated increases in productivity.
Published Origami-inspired robots can sense, analyze and act in challenging environments
(via sciencedaily.com) A multidisciplinary team has created a new fabrication technique for fully foldable robots that can perform a variety of complex tasks without relying on semiconductors.
Published Robotic hand can identify objects with just one grasp
(via sciencedaily.com) Newly created soft-rigid robotic fingers incorporate powerful sensors along their entire length, enabling them to produce a robotic hand that could accurately identify objects after only one grasp.
Published English language pushes everyone -- even AI chatbots -- to improve by adding
(via sciencedaily.com) Original source A linguistic bias in the English language that leads us to 'improve' things by adding to them, rather than taking away, is so common that it is even ingrained in AI chatbots, a new study reveals.
Published Scientists discover hidden crab diversity among coral reefs
(via sciencedaily.com) The Indo-West Pacific is the largest marine ecosystem on Earth, but scientists who study its diversity have to contend with a problem so well-known it was remarked upon by Charles Darwin: related species in the IWP have similar appearances, making it difficult to assess just how many there are. A new study reveals that nearly identical crab species have one consistently distinguishing feature, which only evolves when their ranges overlap.
Published Can AI predict how you'll vote in the next election?
(via sciencedaily.com) Artificial intelligence technologies like ChatGPT are seemingly doing everything these days: writing code, composing music, and even creating images so realistic you'll think they were taken by professional photographers. Add thinking and responding like a human to the conga line of capabilities. A recent study proves that artificial intelligence can respond to complex survey questions just like a real human.
Published Deep ocean currents around Antarctica headed for collapse, study finds
(via sciencedaily.com) Antarctic circulation could slow by more than 40 per cent over the next three decades, with significant implications for the oceans and the climate.
Published New chip design to provide greatest precision in memory to date
(via sciencedaily.com) Everyone is talking about the newest AI and the power of neural networks, forgetting that software is limited by the hardware on which it runs. But it is hardware become 'the bottleneck.' New collaborators might change that. They believe that they have developed a new type of chip with the best memory of any chip thus far for edge AI (AI in portable devices). To put it in context, right now, ChatGPT is running on a cloud. The new innovation, followed by some further development, could put the power of a mini version of ChatGPT in everyone's personal device. It could make such high-powered tech more affordable and accessible for all sorts of applications.
Published Most of world's salt marshes likely to be underwater by 2100, study concludes
(via sciencedaily.com) Salt marshes are some of the most biologically productive ecosystems on Earth. They play an outsized role in nitrogen cycling, act as carbon sinks, protect coastal development from storm surge, and provide critical habitats and nurseries for many fish, shellfish, and coastal birds. According to new research, more than 90 percent of the world's salt marshes are likely to be underwater by the end of the century. These findings come from a 50-year study of ecosystem changes in Great Sippewissett Marsh in Falmouth, Mass.
