(via sciencedaily.com) Original source A newly developed plant-based plastic material releases nine times less microplastics than conventional plastic when exposed to sunlight and seawater, a new study has found.
Published Drawing inspiration from plants: A metal-air paper battery for wearable devices
(via sciencedaily.com) Original source Drawing inspiration from the way plants breathe, a group of researchers has created a paper-based magnesium-air battery that can be used in GPS sensors or pulse oximeter sensors. Taking advantage of paper's recyclability and lightweight nature, the engineered battery holds promise for a more environmentally friendly source of energy.
Published Unleashing disordered rocksalt oxides as cathodes for rechargeable magnesium batteries
(via sciencedaily.com) Original source Researchers have made a groundbreaking advancement in battery technology, developing a novel cathode material for rechargeable magnesium batteries that enables efficient charging and discharging even at low temperatures.
Published New materials discovered for safe, high-performance solid-state lithium-ion batteries
(via sciencedaily.com) Original source All-solid-state lithium-ion batteries offer enhanced safety and energy density compared to liquid electrolyte counterparts, but face challenges like lower conductivity and insufficient electrode contact. In a recent study, scientists have discovered a stable, highly conductive lithium-ion conductor in the form of a pyrochlore-type oxyfluoride. This innovation addresses the need for non-sulfide solid electrolytes, offering higher conductivity and stability and paves the way for advanced all-solid-state lithium-ion batteries with improved performance and safety.
Published Are high-purity cathode materials truly necessary?
(via sciencedaily.com) Original source Researchers introduce a groundbreaking alternative to reduce secondary battery costs.
Published Going 'back to the future' to forecast the fate of a dead Florida coral reef
(via sciencedaily.com) Original source How coral populations expand into new areas and sustain themselves over time is limited by the scope of modern observations. Going back thousands of years, a study provides geological insights into coral range expansions by reconstructing the composition of a Late Holocene-aged subfossil coral death assemblage in an unusual location in Southeast Florida and comparing it to modern reefs throughout the region. Findings offer a unique glimpse into what was once a vibrant coral reef assemblage and discover if history can repeat itself in the face of climate change.
Published Scientists warn: The grey seal hunt is too large
(via sciencedaily.com) Original source Researchers warn that today's hunting quotas of about 3,000 animals pose a risk to the long-term survival of the grey seal in the Baltic Sea. The conclusions of this new study are based on statistics from 20th century seal hunting and predictions of future climate change.
Published Implantable batteries can run on the body's own oxygen
(via sciencedaily.com) Original source From pacemakers to neurostimulators, implantable medical devices rely on batteries to keep the heart on beat and dampen pain. But batteries eventually run low and require invasive surgeries to replace. To address these challenges, researchers have devised an implantable battery that runs on oxygen in the body. The study shows in rats that the proof-of-concept design can deliver stable power and is compatible with the biological system.
Published Severe hurricanes boost influx of juveniles and gene flow in a coral reef sponge
(via sciencedaily.com) Original source A study is the first to evaluate substrate recolonization by sponges in the U.S. Virgin Islands after two catastrophic storms using genetic analyses to understand how much clonality verses sexual recruitment occurs on coral reefs post-storms. Results show that populations of clonal marine species with low pelagic dispersion, such as A. cauliformis, may benefit from increased frequency and magnitude of hurricanes to maintain genetic diversity and combat inbreeding, enhancing the resilience of Caribbean sponge communities to extreme storm events.
Published Two coral snakes recorded battling for prey in a scientific first
(via sciencedaily.com) Original source Two red-tailed coral snakes have been observed competing over a caecilian in the first documented wild case of kleptoparasitism within the family Elapidae.
Published Citizen scientists contribute vital information about 35 seahorse species
(via sciencedaily.com) Original source Thanks to diligent observers, seahorses, those enigmatic and charismatic fish, are not only being discovered in new habitats and expanded geographic ranges, they are also being found at new ocean depths. While their capacity for male pregnancy has long fascinated people, new information on sex ratio and pregnancy seasonality has been discovered.
Published New all-liquid iron flow battery for grid energy storage
(via sciencedaily.com) Original source A new iron-based aqueous flow battery shows promise for grid energy storage applications.
Published Caller ID of the sea: Tagging whale communication and behavior
(via sciencedaily.com) Original source Biologists use a novel method of simultaneous acoustic tagging to gain insights into the link between whale communication and behavior
Published Rays were more diverse 150 million years ago than previously thought
(via sciencedaily.com) Original source Scientists have explored the puzzling world of rays that lived 150 million years ago and discovered a previously hidden diversity -- including a new ray species. This study significantly expands the understanding of these ancient cartilaginous fish and provides further insights into a past marine ecosystem.
Published Entanglements of humpback whales in fish farms rare -- and naivety could be to blame
(via sciencedaily.com) Original source The first study of humpback whale entanglements in B.C. aquaculture facilities found eight over 13 years, with the curiosity of young whales a potential contributing factor.
Published Forest, stream habitats keep energy exchanges in balance, global team finds
(via sciencedaily.com) Original source Forests and streams are separate but linked ecosystems, existing side by side, with energy and nutrients crossing their porous borders and flowing back and forth between them. For example, leaves fall from trees, enter streams, decay and feed aquatic insects. Those insects emerge from the waters and are eaten by birds and bats. An international team has now found that these ecosystems appear to keep the energy exchanges in balance -- a finding that the scientists called surprising.
Published Scientists weigh up current status of blue whale populations around the world
(via sciencedaily.com) Original source The largest living animal, the blue whale (Balaenoptera musculus) which averages about 27 meters in length, has slowly recovered from whaling only to face the rising challenges of global warming, pollution, disrupted food sources, shipping, and other human threats. In a major new study, biologists have taken a stock of the number, distribution and genetic characteristics of blue whale populations around the world and found the greatest differences among the eastern Pacific, Antarctic subspecies and pygmy subspecies of the eastern Indian and western Pacific.
Published Killer whales use specialized hunting techniques to catch marine mammals in the open ocean
(via sciencedaily.com) Original source Killer whales foraging in deep submarine canyons off the coast of California represent a distinct subpopulation that uses specialized hunting techniques to catch marine mammals, researchers report.
Published Ancient giant dolphin discovered in the Amazon
(via sciencedaily.com) Original source Measuring between 3 to 3.5 meters, 16 million years old: Paleontologists have announced the discovery of a new species of freshwater dolphin in the Peruvian Amazon region. Surprisingly, its closest living relatives can be found in the river dolphins of South Asia.
Published Crawfish could transfer ionic lithium from their environment into food chain
(via sciencedaily.com) Original source Lithium-ion rechargeable batteries are showing up in ever more devices, and the increasing use of this technology means more lithium is expected to find its way into the environment as a contaminant. In new research, a team has explored how this ion accumulates in a common Southern crustacean, the crawfish, with implications for the environment and public health.
