Published Self-repairing mitochondria use novel recycling system
(via sciencedaily.com) Original source A newly identified identified cellular mechanism allows mitochondria to recycle localized damage and maintain healthy function.
Published Mobile species are 'glue' which connect different habitats together
(via sciencedaily.com) Original source A groundbreaking study conducted across 30 field sites in the southwest UK has revealed the importance of incorporating varied habitats into the landscape at large.
Published Hydropower generation projected to rise, but climate change brings uncertain future
(via sciencedaily.com) Original source Although climate change may bring increased precipitation to many parts of the United States, some areas may face drier conditions and lower streamflow, resulting in decreased hydropower generation.
Published Surprising mechanism for removing dead cells identified
(via sciencedaily.com) Original source A tandem signaling process turns ordinary cells into an efficient cleanup crew.
Published Biophysics: From filament pick-up sticks to active foams
(via sciencedaily.com) Original source Physicists have developed a new model that describes how filaments assemble into active foams.
Published Sharing risk to avoid power outages in an era of extreme weather
(via sciencedaily.com) Original source Heat waves, droughts, and fires place growing stress on the West's electric grid. New research suggests that more integrated management of electricity resources across the region could significantly reduce the risk of power outages and accelerate the transition to clean energy.
Published Molecular wires with a twist
(via sciencedaily.com) Original source Researchers have developed molecular wires with periodic twists. By controlling the lengths of regions between twists, the electrical conductivity of individual polymer chains can be enhanced. This work may lead to novel organic electronics or single-molecule wires.
Published Compound in rosemary extract can reduce cocaine sensitivity
(via sciencedaily.com) Original source A team of researchers has discovered that an antioxidant found in rosemary extract can reduce volitional intakes of cocaine by moderating the brain's reward response, offering a new therapeutic target for treating addiction.
Published Renewable energy policies provide benefits across state lines
(via sciencedaily.com) Original source New research suggests U.S. states with clean energy policies provide benefits to their neighbors, including states without their own renewable energy policies.
Published Researchers teaching artificial intelligence about frustration in protein folding
(via sciencedaily.com) Original source Scientists have found a new way to predict how proteins change their shape when they function, which is important for understanding how they work in living systems. While recent artificial intelligence (AI) technology has made it possible to predict what proteins look like in their resting state, figuring out how they move is still challenging because there is not enough direct data from experiments on protein motions to train the neural networks.
Published Gut bioelectricity provides a path for 'bad' bacteria to cause diseases
(via sciencedaily.com) Original source Researchers have discovered a novel bioelectrical mechanism that pathogens like Salmonella use to find entry points in the gut lining that would allow pathogens to pass and cause infection.
Published Humpbacks are among animals who manufacture and wield tools
(via sciencedaily.com) Original source Researchers suggest a new designation of the humpback whales they study: tool wielders. Researchers have known that humpback whales create "bubble-nets" to hunt, but they have learned that the animals don't just create the bubble-nets; they manipulate this unique tool in a variety of ways to maximize their food intake in Alaskan feeding grounds.
Published Hospital bacteria tracked better than ever before with new technique
(via sciencedaily.com) Original source New method provides high-resolution surveillance data about multiple common antibiotic-resistant bacteria at once and could help prevent the spread of infections.
Published Environmental laws failing to slow deforestation
(via sciencedaily.com) Original source Australia's environmental laws are failing to stop high rates of tree clearing to make way for agriculture, development and mining.
Published Mother's gut microbiome during pregnancy shapes baby's brain development
(via sciencedaily.com) Original source A study in mice has found that the bacteria Bifidobacterium breve in the mother's gut during pregnancy supports healthy brain development in the fetus.
Published Incorporating humidity improves estimations of climate impacts on health
(via sciencedaily.com) Original source Governments, medical institutions and other bodies require accurate models on health-related matters in order to better organize their activities. Climate change has measurable impacts on society, including on human mortality. However, current models to assess the health impacts of climate change do not account for every environmental parameter, especially humidity, which could influence heat stress perceived by the human body, leaving room for improvement. Researchers have now incorporated humidity data from hundreds of cities into so-called heat stress indicators (HSIs) and assessed their performances in predicting heat-related deaths.
Published New view of North Star reveals spotted surface
(via sciencedaily.com) Original source High-resolution images show large spots on the surface of Polaris.
Published How early-life antibiotics turn immunity into allergy
(via sciencedaily.com) Original source Researchers have shown how and why the depletion of microbes in a newborn's gut by antibiotics can lead to lifelong respiratory allergies. The research team identified a specific cascade of events that lead to allergies and asthma, opening many new avenues for exploring potential preventions and treatments.
Published 'Masters of shape-shifting': How darkling beetles conquered the world
(via sciencedaily.com) Original source Large-scale genomic analysis of darkling beetles, a hyper-diverse insect group of more than 30,000 species worldwide, rolls back the curtain on a 150-million-year evolutionary tale of one of Earth's most ecologically important yet inconspicuous creatures, according to new research.
Published Demand for low-quality credits undermines the voluntary carbon market, study finds
(via sciencedaily.com) Original source Researchers have shown that the 20 companies retiring the most offsets from the voluntary carbon market -- or VCM -- over the past four years have largely relied on low-quality, low-cost credits. These include major oil companies, airlines and aircraft makers, automotive manufacturers, logistics operators, and others.
