Published Can pigeons match wits with artificial intelligence?
(via sciencedaily.com) Can a pigeon match wits with artificial intelligence? Researchers tested pigeons' learning abilities and concluded the birds employ the same basic process, called associative learning, as the most advanced AI technologies.
Published Plastic debris in the Arctic comes from all around the world
(via sciencedaily.com) In the course of five years, citizens who went on sailing cruises to the Arctic surveyed and collected plastic debris that had washed up on the shores of Svalbard. This has now been analyzed. According to the findings, one third of the plastic debris which still bore imprints or labels allowing an analysis of their origin came from Europe, and much of that number from Germany.
Published Long-term restoration of a biodiversity hotspot hinges on getting seeds to the right place at the right time
(via sciencedaily.com) New research shows that degraded savanna ecosystems can reap lasting benefits from a single seeding of native understory plants. Once a diverse understory of savanna plants became established, its long-term persistence was relatively unaffected by environmental factors -- with one exception. Higher temperatures during the height of the growing season were associated with poorer long-term survival among some species, indicating one threat posed by a warming climate.
Published More frequent atmospheric rivers hinder seasonal recovery of Arctic sea ice
(via sciencedaily.com) The Arctic is rapidly losing sea ice, even during winter months when temperatures are below freezing and ice should be recovering from the summer melt. A new study found powerful storms called atmospheric rivers are increasingly reaching the Arctic in winter, slowing sea ice recovery and accounting for a third of all winter sea ice decline, according to a team led by Penn State scientists.
Published Pacific Northwest heat dome tree damage more about temperature than drought, scientists say
(via sciencedaily.com) Original source Widespread tree scorch in the Pacific Northwest that became visible shortly after multiple days of record-setting, triple-digit temperatures in June 2021 was more attributable to heat than to drought conditions, researchers say.
Published Interactive cyber-physical human: Generating contact-rich whole-body motions
(via sciencedaily.com) Performing human-like motions that involve multiple contacts is challenging for robots. In this regard, a researcher has envisioned an interactive cyber-physical human (iCPH) platform with complementary humanoid (physical twin) and simulation (digital twin) elements. iCPH combines human measurement data, musculoskeletal analysis, and machine learning for data collection and augmentation. As a result, iCPH can understand, predict, and synthesize whole-body contact motions.
Published Robot: I'm sorry. Human: I don't care anymore!
(via sciencedaily.com) Humans are less forgiving of robots after multiple mistakes -- and the trust is difficult to get back, according to a new study.
Published Forest trees find a new watery 'sweet spot' when CO2 is high
(via sciencedaily.com) Original source Trees living in conditions where the carbon dioxide (CO2) has been artificially elevated are likely to become more efficient in conserving water.
Published Wildfires are increasingly burning California's snowy landscapes and colliding with winter droughts to shrink California's snowpack
(via sciencedaily.com) A research team examined what happens to mountain snowpacks when sunny, midwinter dry spells occur in forests impacted by severe wildfire.
Published Mistaken fossil rewrites history of Indian subcontinent for second time
(via sciencedaily.com) Scientists discovered the first-ever Dickinsonia fossil in India two years ago, changing our understanding of how the continent came to be. Now, new research shows the 'fossil' was just a beehive all along, changing our understanding for a second time, and the original scientists now support the new findings.
Published Climate change may cut US forest inventory by a fifth this century
(via sciencedaily.com) Original source A study found that under more severe climate warming scenarios, the inventory of trees used for timber in the continental United States could decline by as much as 23% by 2100. The largest inventory losses would occur in two of the leading timber regions in the U.S., which are both in the South.
Published New approach to 'punishment and reward' method of training artificial intelligence offers potential key to unlock new treatments for aggressive cancers
(via sciencedaily.com) A new 'outside-the-box' method of teaching artificial intelligence (AI) models to make decisions could provide hope for finding new therapeutic methods for cancer, according to a new study.
Published With rapidly increasing heat and drought, can plants adapt?
(via sciencedaily.com) As deserts expanded their range over the past 5-7 million years, many plants invaded the new biome and rapidly diversified, producing amazing adaptations to drought and heat. Can plants continue to adapt to increasing aridity caused by climate change? A new study that addressed the origins of desert adaptation concluded that one group of desert plants, rock daisies, came preadapted to aridity, likely helping them survive desert conditions. Not all plants may be so lucky.
Published Aquatic organisms respond to flooding and drought disturbance in different ways
(via sciencedaily.com) Populations of various species of aquatic insects and other invertebrates respond to flooding and waterway drying due to drought in different ways that can be anticipated, according to a new study that employed a novel method to assess the stability of stream ecosystems.
Published Deer browsing is just one of many factors shaping North American forests
(via sciencedaily.com) In a new study, a research team discovered evidence that browsing by white-tailed deer had relatively little long-term impact on two tree species in a northern forest.
Published Legged robots need more testing before real-world use
(via sciencedaily.com) When it comes to the 'evolution' of mobile robots, it may be a long time before legged robots are able to safely interact in the real world, according to a new study.
Published GPS tracking, simulations show optimal locations to help desert bighorn sheep cross freeways
(via sciencedaily.com) Desert bighorn sheep whose Southern California range is bisected by freeways may one day benefit from modeling designed to show where the animals would be most apt to use overpasses to safely cross the interstates.
Published A fairy-like robot flies by the power of wind and light
(via sciencedaily.com) The loss of pollinators, such as bees, is a huge challenge for global biodiversity and affects humanity by causing problems in food production. Researchers have now developed the first passively flying robot equipped with artificial muscle. Could this artificial fairy be utilized in pollination?
Published AI technology generates original proteins from scratch
(via sciencedaily.com) Scientists have created an AI system capable of generating artificial enzymes from scratch. In laboratory tests, some of these enzymes worked as well as those found in nature, even when their artificially generated amino acid sequences diverged significantly from any known natural protein.
Published Versatile robo-dog runs through the sandy beach at 3 meters per second
(via sciencedaily.com) Meet the new addition to the robo-dog family, 'RaiBo', that can run along the sandy beach without losing balance and walk through grassy fields and back on the hard-floored tracking fields all on its own -- no further tinkering necessary.
