Published Discovery of three novel minorisa species, the smallest predatory marine picoplankton
(via sciencedaily.com) Original source Researchers have made a significant discovery by identifying and characterizing three novel species within the Minorisa genus of marine picoplankton. Before this study, only one species of Minorisa was recognized. This finding reveals previously unseen diversity of Minorisa, thereby enhancing species identification and our understanding of its ecological functions in marine ecosystems.
Published Endangered whales live in area earmarked for gas exploration
(via sciencedaily.com) Original source Endangered whales and dolphins live year-round in an area of the Mediterranean earmarked for oil and gas exploration, new research shows.
Published Vision via sound for the blind
(via sciencedaily.com) Original source Smart glasses that use a technique similar to a bat's echolocation could help blind and low-vision people navigate their surroundings, according to researchers.
Published Algae's surprising potential to help ease climate change worries
(via sciencedaily.com) Original source The key to bringing global net-zero goals into reach may be algae, say researchers. Studies show impressive success of certain microalgae varieties to remove CO2 from the atmosphere then break it down into useful materials.
Published Rider on the storm: Shearwater seabird catches an 11 hour ride over 1,000 miles in a typhoon
(via sciencedaily.com) Original source New research suggests that increasingly severe weather driven by climate change may push oceangoing seabirds to their limits.
Published On the trail of the silver king: Researchers reveal unprecedented look at tarpon migration
(via sciencedaily.com) Original source New research unveils a dataset, gathered over five years, that gives the finest-grained detail into the timing and spatial extent of tarpon migration. The work leveraged networks of thousands of acoustic receivers that tracked 200 tarpon over more than five years. One of the key findings is that there are two distinct subgroups of tarpon, which has immediate implications for efforts to conserve the fish, known to anglers as the 'Silver King.'
Published Bizarre new fossils shed light on ancient plankton
(via sciencedaily.com) Original source Recently discovered microfossils date back half a billion years. Resembling modern-day algae, they provide insight into early life in our oceans.
Published Tiny spirits roam the corals of Japan -- two new pygmy squids discovered
(via sciencedaily.com) Original source Named after Japanese folklore, two cephalopod species have been discovered in the coastal waters of the Okinawa Islands.
Published Light, freshwater sticks to Greenland's east coast
(via sciencedaily.com) Original source Meltwater that runs along the east coast of Greenland, hardly enters the open ocean before reaching the western side of the island. In the changing climate, fresh water from Greenland and the Arctic could disrupt the circulation in the Atlantic Ocean.
Published Smartphone attachment could increase racial fairness in neurological screening
(via sciencedaily.com) Original source A new smartphone attachment could enable people to screen for a variety of neurological conditions, such as Alzheimer's disease and traumatic brain injury, at low cost -- and do so accurately regardless of their skin tone. The attachment fits over a smartphone's camera to capture clear video of pupil size changes, which can offer clues about an individual's neurological functions. The device helps the camera see the pupil easily in dark eye colors.
Published Adaptive optical neural network connects thousands of artificial neurons
(via sciencedaily.com) Original source Physicists working with computer specialists have developed a so-called event-based architecture, using photonic processors. In a similar way to the brain, this makes possible the continuous adaptation of the connections within the neural network.
Published Soft, living materials made with algae glow under stress
(via sciencedaily.com) Original source Researchers have developed soft yet durable materials that glow in response to mechanical stress, such as compression, stretching or twisting. The materials derive their luminescence from single-celled algae known as dinoflagellates, which are embedded within the materials. The work was inspired by the bioluminescent waves caused by dinoflagellates during red tide events at San Diego's beaches.
Published Ancient sea monster remains reveal oldest mega-predatory pliosaur
(via sciencedaily.com) Original source The fossils of a 170-million-year-old ancient marine reptile from the Age of Dinosaurs have been identified as the oldest-known mega-predatory pliosaur -- a group of ocean-dwelling reptiles closely related to the famous long-necked plesiosaurs. The findings are rare and add new knowledge to the evolution of plesiosaurs.
Published Soil carried on sea freight loaded with dangerous pests and diseases, research finds
(via sciencedaily.com) Original source While sea freight is recognised as a pathway for the movement of exotic organisms, there is little research that has quantified the risk. Soil collected from the external surfaces of sea freight was found to support live microorganisms, worms, seeds and insects, including various regulated biosecurity organisms. The research confirms that shipping containers provide a pathway for the movement of exotic species.
Published Eyes may be the window to your soul, but the tongue mirrors your health
(via sciencedaily.com) Original source A 2000-year-old practice by Chinese herbalists -- examining the human tongue for signs of disease -- is now being embraced by computer scientists using machine learning and artificial intelligence.
Published DNA shows where Washington culvert replacements helped spawning salmon
(via sciencedaily.com) Original source University and federal scientists used genetic sleuthing to study how salmon were affected by two major culvert replacements near the city of Bellingham. One project, a major upgrade under Interstate-5, had a big impact, while the other old culvert may have been less of a barrier to fish. Authors from the UW and NOAA are studying the use of environmental DNA, or eDNA, in future environmental impact reporting.
Published International team develops novel DNA nano engine
(via sciencedaily.com) Original source An international team of scientists has recently developed a novel type of nano engine made of DNA. It is driven by a clever mechanism and can perform pulsing movements. The researchers are now planning to fit it with a coupling and install it as a drive in complex nano machines.
Published Scientists discover deepest known evidence of coral reef bleaching
(via sciencedaily.com) Original source Scientists have discovered the deepest known evidence of coral reef bleaching, more than 90 metres below the surface of the Indian Ocean. Identified during a research cruise, the damage to the deeper reefs in the Central Indian Ocean has been attributed to significant changes in the region's ocean temperature caused by the Indian Ocean Dipole. The researchers have also warned such incidences are only likely to increase as a result of present and future climate change.
Published Waves of change: How sea-levels and climate altered the marine ecosystems at the South Pole 390-385 million years ago
(via sciencedaily.com) Original source New research reveals a chain of environmental disasters. These took place in what is today's South Africa, during an ancient time period called the Early-Middle Devonian. The crises led to the extinction of a unique group of marine animals called the Malvinoxhosan biota.
Published Physical theory improves protein folding prediction
(via sciencedaily.com) Original source Proteins are important molecules that perform a variety of functions essential to life. To function properly, many proteins must fold into specific structures. However, the way proteins fold into specific structures is still largely unknown. Researchers have developed a novel physical theory that can accurately predict how proteins fold. Their model can predict things previous models cannot. Improved knowledge of protein folding could offer huge benefits to medical research, as well as to various industrial processes.
