Published Study finds nearly half of U.S. counties have at least one 'pharmacy desert'
(via sciencedaily.com) Original source Nearly half of counties in the United States have at least one 'pharmacy desert' where there is no retail pharmacy within 10 miles, according to a new study.
Published Two epicenters led to Japan's violent Noto earthquake on New Year's Day
(via sciencedaily.com) Original source The 7.5- magnitude earthquake beneath Japan's Noto Peninsula on Jan. 1, 2024, occurred when a 'dual-initiation mechanism' applied enough energy from two different locations to break through a fault barrier -- an area that locks two sides of a fault in place and absorbs the energy of fault movement, slowing it down or stopping it altogether.
Published A leaky sink: Carbon emissions from forest soil will likely grow with rising temperatures
(via sciencedaily.com) Original source The soils of northern forests are key reservoirs that help keep the carbon dioxide that trees inhale and use for photosynthesis from making it back into the atmosphere.
Published NASA's DART impact permanently changed the shape and orbit of asteroid moon
(via sciencedaily.com) Original source A new study provides insights on the geophysics behind asteroid formation and evolution.
Published Innovative field experiments shed light on biological clocks in nature
(via sciencedaily.com) Original source A new study has used a series of innovative field experiments to show how plants combine circadian clock signals with environmental cues under naturally fluctuating conditions.
Published Scientists call for an update in environmental decision making that takes human rights into account
(via sciencedaily.com) Original source Researchers argue that to protect human wellbeing global decisions with the potential to impact the environment must be guided by our understanding of the inseparable connection between humans and nature. The article's authors are aiming to support fair and inclusive decision-making for a healthy ocean for people and planet.
Published Toward a code-breaking quantum computer
(via sciencedaily.com) Original source Building on a landmark algorithm, researchers propose a way to make a smaller and more noise-tolerant quantum factoring circuit for cryptography.
Published Colorful traits in primates ease tensions between groups
(via sciencedaily.com) Original source Primate ornamentation plays a crucial role in communication not only within social groups but also between them, according to a new study. The research reveals that the males of species with overlapping home ranges often display vibrant colors or elaborate features, traits that may help reduce intergroup aggression by enabling quick assessments of potential rivals.
Published Life after (feigned) death
(via sciencedaily.com) Original source A new study has revealed what animals do after they have feigned death in order to avoid being killed by a predator and what the context of this behavior is.
Published Mitochondria are flinging their DNA into our brain cells
(via sciencedaily.com) Original source A new study finds that mitochondria in our brain cells frequently fling their DNA into the cells' nucleus, where the mitochondrial DNA integrates into chromosomes, possibly causing harm.
Published Creature the size of a dust grain found hiding in California's Mono Lake
(via sciencedaily.com) Original source Mono Lake is a beautiful but harsh environment, its salty and arsenic-laced water home to brine shrimp, alkali flies and little else. Scientists recently discovered an unsuspected resident, however, a microscopic creature -- a choanoflagelatte -- that forms colonies that harbor their own unique bacterial microbiomes. The creature, part of the sister group to all animals, could shed light on the evolution of animals' intimate interactions with bacteria and the rise of multicellular life.
Published Fighting coastal erosion with electricity
(via sciencedaily.com) Original source New research has systematically demonstrated that a mild zap of electricity can strengthen a marine coastline for generations -- greatly reducing the threat of erosion in the face of climate change and rising sea levels. The new process forms natural cement between grains of sand, transforming it into solid, immoveable rock. Mollusks use a similar process to turn naturally occurring minerals into shells.
Published DNA tech offers both data storage and computing functions
(via sciencedaily.com) Original source Researchers have demonstrated a technology capable of a suite of data storage and computing functions -- repeatedly storing, retrieving, computing, erasing or rewriting data -- that uses DNA rather than conventional electronics. Previous DNA data storage and computing technologies could complete some but not all of these tasks.
Published Will EEG be able to read your dreams? The future of the brain activity measure as it marks 100 years
(via sciencedaily.com) Original source One hundred years after the human brain's electrical activity was first recorded, experts are celebrating the legacy of its discovery and sharing their predictions and priorities for its future. A survey saw respondents -- with 6,685 years of collective experience -- presented with possible future developments for EEG, ranging from those deemed 'critical to progress' to the 'highly improbable,' and asked to estimate how long it might be before they were achieved.
Published Tarantulas have surprising partnerships with other species and their hairiness may be a defense mechanism
(via sciencedaily.com) Original source A new study reveals that tarantulas are often on friendly terms with amphibians, reptiles, and even army ants, which are known to feed on spiders. The researchers suggest that the dense hair covering tarantulas may have in fact evolved as a defense mechanism against these predatory ants.
Published Hydrogels can play Pong by 'remembering' previous patterns of electrical simulation
(via sciencedaily.com) Original source Non-living hydrogels can play the video game Pong and improve their gameplay with more experience, researchers report. The researchers hooked hydrogels up to a virtual game environment and then applied a feedback loop between the hydrogel's paddle -- encoded by the distribution of charged particles within the hydrogel -- and the ball's position -- encoded by electrical stimulation. With practice, the hydrogel's accuracy improved by up to 10%, resulting in longer rallies. The researchers say that this demonstrates the ability of non-living materials to use 'memory' to update their understanding of the environment, though more research is needed before it could be said that hydrogels can 'learn.'
Published Alzheimer's drug may someday help save lives by inducing a state of 'suspended animation'
(via sciencedaily.com) Original source Researchers have found that an Alzheimer's drug, donepezil, can induce a safe and reversible torpor-like state in tadpoles of the Xenopus laevis species at room temperature. This 'biostasis' achievement could offer a way to slow down the human body's processes and buy patients more time to survive critical injuries and diseases, even when disaster strikes far from a hospital.
Published Antarctica vulnerable to invasive species hitching rides on plastic and organic debris
(via sciencedaily.com) Original source A new study reveals how ocean biology and marine pollution can end up on Antarctica's shoreline.
Published A deep dive for environmental data on coastal oceans
(via sciencedaily.com) Original source A new study addresses the lack of data on how much human-generated carbon dioxide is present in coastal oceans -- the saltwater ecosystems that link the land and sea. Capturing this data is crucial to calculating how much emissions must be cut in the future.
Published To kill mammoths in the Ice Age, people used planted pikes, not throwing spears, researchers say
(via sciencedaily.com) Original source Archeologists say new findings might help resolve the debate about Clovis points and reshape how we think about what life was like roughly 13,000 years ago. After an extensive review of writings and artwork -- and an experiment with replica Clovis point spears -- a team of archaeologists says humans may have braced the butt of their weapons against the ground in a way that would impale a charging animal. The force would have driven the spear deeper into the predator's body, unleashing a more damaging blow than even the strongest prehistoric hunters would have been capable of by throwing or jabbing megafauna.
