Published Occupational exposure to particles may increase the risk of chronic kidney disease
(via sciencedaily.com) Original source Exposure to dust and particles at work may increase the risk of chronic kidney disease, a new study shows. Among Swedish construction workers, followed since the 1970s, the risk was 15% higher among exposed.
Published 'DNA scavengers' can stop some antibiotic resistance from spreading
(via sciencedaily.com) Original source For nearly a century, scientists have waged war on antibiotic-resistant microbes. Researchers say they've found a new way to prevent it -- by unleashing 'DNA scavengers' in wastewater treatment plants.
Published AI approach to drought zoning
(via sciencedaily.com) Original source A recent study shows that climate change may cause many areas in Canada to experience significant droughts by the end of the century. In response, the researchers have introduced an advanced AI-based method to map drought-prone regions.
Published Engineered Bacteria make thermally stable plastics similar to polystyrene and PET
(via sciencedaily.com) Original source Bioengineers around the world have been working to create plastic-producing microbes that could replace the petroleum-based plastics industry. Now, researchers have overcome a major hurdle: getting bacteria to produce polymers that contain ring-like structures, which make the plastics more rigid and thermally stable. Because these molecules are usually toxic to microorganisms, the researchers had to construct a novel metabolic pathway that would enable the E. coli bacteria to both produce and tolerate the accumulation of the polymer and the building blocks it is composed of. The resulting polymer is biodegradable and has physical properties that could lend it to biomedical applications such as drug delivery, though more research is needed.
Published Benefits and downside of fasting
(via sciencedaily.com) Original source Researchers identified a signaling pathway in mice that boosts intestinal stem cells' regeneration abilities after fasting. When cancerous mutations occurred during this regenerative period, mice were more likely to develop early-stage intestinal tumors.
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 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 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 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 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 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.
