Published 'Smart' walking stick could help visually impaired with groceries, finding a seat
(via sciencedaily.com) For people who are blind or visually impaired, finding the right products in a crowded grocery store can be difficult without help. A team of computer scientists is trying to change that.
Published Malformed seashells, ancient sediment provide clues about Earth's past
(via sciencedaily.com) Shrunken seashells and unusually dark sediment cores have helped geoscientists better understand the chronology and character of events that led to Ocean Anoxic Event 2, nearly 100 million years ago.
Published In the Neanderthal site of Combe-Grenal, France, hunting strategies were unaffected by changing climate
(via sciencedaily.com) Neanderthals in Combe-Grenal (France) preferred to hunt in open environments, and their hunting strategies did not alter during periods of climatic change, according to a new study.
Published Global warming reaches central Greenland
(via sciencedaily.com) A temperature reconstruction from ice cores of the past 1,000 years reveals that today's warming in central-north Greenland is surprisingly pronounced. The most recent decade surveyed in a study, the years 2001 to 2011, was the warmest in the past 1,000 years, and the region is now 1.5 °C warmer than during the 20th century, as researchers report. Using a set of ice cores unprecedented in length and quality, they reconstructed past temperatures in central-north Greenland and melting rates of the ice sheet.
Published A precision arm for miniature robots
(via sciencedaily.com) Until now, microscopic robotic systems have had to make do without arms. Now researchers have developed an ultrasonically actuated glass needle that can be attached to a robotic arm. This lets them pump and mix minuscule amounts of liquid and trap particles.
Published Feathered robotic wing paves way for flapping drones
(via sciencedaily.com) Birds fly more efficiently by folding their wings during the upstroke, according to a recent study. The results could mean that wing-folding is the next step in increasing the propulsive and aerodynamic efficiency of flapping drones.
Published Study offers most detailed glimpse yet of planet's last 11,000 summers and winters
(via sciencedaily.com) An international team of collaborators have revealed the most detailed look yet at the planet's recent climactic history, including summer and winter temperatures dating back 11,000 years to the beginning of what is known as the Holocene.
Published Project aims to expand language technologies
(via sciencedaily.com) Only a fraction of the 7,000 to 8,000 languages spoken around the world benefit from modern language technologies like voice-to-text transcription, automatic captioning, instantaneous translation and voice recognition. Researchers want to expand the number of languages with automatic speech recognition tools available to them from around 200 to potentially 2,000.
Published Rodent extinctions in Hispaniola may have been caused by humans
(via sciencedaily.com) Hispaniola once had among the highest diversity of rodents in the Caribbean. Today, only one rodent species remains, and its prospects for survival are uncertain. New carbon dates place the blame squarely on humans.
Published Climate change could cause 'disaster' in the world's oceans
(via sciencedaily.com) Original source Climate change will slow down deep overturning ocean circulation in the coming centuries. Using three dozen Earth system models, researchers have concluded that the Southern Meridional Overturning Circulation could completely shut down by 2300, causing disaster to the marine ecosystem on a large portion of the planet.
Published Bering Land Bridge formed surprisingly late during last ice age
(via sciencedaily.com) A new study that reconstructs the history of sea level at the Bering Strait shows that the Bering Land Bridge connecting Asia to North America did not emerge until around 35,700 years ago, less than 10,000 years before the height of the last ice age (known as the Last Glacial Maximum). The findings indicate that the growth of the ice sheets -- and the resulting drop in sea level -- occurred surprisingly quickly and much later in the glacial cycle than previous studies had suggested.
Published Can the AI driving ChatGPT help to detect early signs of Alzheimer's disease?
(via sciencedaily.com) The artificial intelligence algorithms behind the chatbot program ChatGPT -- which has drawn attention for its ability to generate humanlike written responses to some of the most creative queries -- might one day be able to help doctors detect Alzheimer's Disease in its early stages. Research recently demonstrated that OpenAI's GPT-3 program can identify clues from spontaneous speech that are 80% accurate in predicting the early stages of dementia.
Published Words prove their worth as teaching tools for robots
(via sciencedaily.com) What is the best way to teach a robot? Sometimes it may simply be to speak to it clearly. Researchers found that human-language descriptions of tools can accelerate the learning of a simulated robotic arm lifting and using a variety of tools.
Published Cheerful chatbots don't necessarily improve customer service
(via sciencedaily.com) Humans displaying positive emotions in customer service interactions have long been known to improve customer experience, but researchers wanted to see if this also applied to AI. They conducted experimental studies to determine if positive emotional displays improved customer service and found that emotive AI is only appreciated if the customer expects it, and it may not be the best avenue for companies to invest in.
Published Should we tax robots?
(via sciencedaily.com) A small tax on robots, as well as on trade generally, will help reduce income inequality in the U.S., according to economists.
Published Early forests did not significantly change the atmospheric CO2
(via sciencedaily.com) Original source Scientists have discovered that the atmosphere contained far less CO2 than previously thought when forests emerged on our planet, the new study has important implications for understanding how land plants affect the climate.
Published New theory on timing for human settlement of some parts of tropical Pacific
(via sciencedaily.com) Spread across vast distances, the islands of the tropical Pacific Ocean are thought to have been populated by humans in two distinct migrations beginning approximately 3,330 years ago. The first followed a northern route out of what is today the Philippines and the second followed a southern route from Taiwan and New Guinea. People arrived on the islands between these routes -- now making up the Federated States of Micronesia -- about 1,000 years later. But a new finding by sea-level researchers suggests that the islands in Micronesia were possibly settled much earlier than supposed and that voyagers on the two routes may have interacted with one another.
Published New winged robot can land like a bird
(via sciencedaily.com) Researchers have developed a method that allows a flapping-wing robot to land autonomously on a horizontal perch using a claw-like mechanism. The innovation could significantly expand the scope of robot-assisted tasks.
Published Linking fossil climate proxies to living bacteria helps climate predictions
(via sciencedaily.com) Fossilized microbial skins can give us a glimpse of how the climate was in the deep geological past. By discovering the 'missing link' between such fossil skins and the skins of living bacteria, researchers have greatly improved the accuracy of climate reconstructions and predictions.
Published Climate change played key role in dinosaur success story
(via sciencedaily.com) Climate change, rather than competition, played a key role in the ascendancy of dinosaurs through the Late Triassic and Early Jurassic periods.
