Published Cell division quality control 'stopwatch' uncovered
(via sciencedaily.com) Original source Biologists have uncovered a quality control timing mechanism tied to cell division. The 'stopwatch' function keeps track of mitosis and acts as a protective measure when the process takes too long, preventing the formation of cancerous cells.
Published How built environment correlates with risk of cardiovascular disease
(via sciencedaily.com) Original source Researchers have studied hundreds of elements of the built environment, including buildings, green spaces, pavements and roads, and how these elements relate to each other and influence coronary artery disease in people living in these neighborhoods. Their findings show that these factors can predict 63% of the variation in the risk of coronary heart disease from one area to another.
Published Parental avoidance of toxic exposures could help prevent autism, ADHD in children, new study shows
(via sciencedaily.com) Original source Researchers have found that parents with chemical intolerance are more likely to report children with autism and ADHD.
Published Open waste burning linked to air pollution in Northwestern Greenland
(via sciencedaily.com) Original source A case study on the effects of open waste burning on air quality in Northwestern Greenland calls attention to the importance of no-one-left-behind sustainable air quality monitoring in the Arctic region.
Published Study unlocks the power of visible light for sustainable chemistry
(via sciencedaily.com) Original source A breakthrough in sustainable molecular transformations has been announced. Chemists have developed an important way to harness the power of visible light to drive chemical processes with greater efficiencies, offering a greener alternative to traditional methods.
Published Synaptic protein change during development offers clues on evolution and disease
(via sciencedaily.com) Original source An analysis of how synaptic proteins change during early development reveals differences between mice and marmosets but also what's different in individuals with autism spectrum disorders. The findings offer first insights into the mechanism behind synaptic development and open up routes for research on possible treatments.
Published New method developed to isolate HIV particles
(via sciencedaily.com) Original source Researchers have developed a new method to isolate HIV from samples more easily, potentially making it easier to detect infection with the virus. They focus on peptide nanofibrils (PNFs) on magnetic microparticles, a promising tool and hybrid material for targeted binding and separation of viral particles.
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 How extratropical ocean-atmosphere interactions can contribute to the variability of jet streams in the Northern Hemisphere
(via sciencedaily.com) Original source Ocean-atmosphere coupling, the exchange in energy between the ocean and atmosphere, influences teleconnection patterns, the climate effects across vast geographical areas. However, its impact outside the tropics is unclear. A group of researchers examined the effect of ocean coupling on atmospheric circulation patterns in the Northern Hemisphere. They found that extratropical ocean-atmosphere coupling enhances teleconnection patterns and causes more meandering westerly jet streams, which are linked to extreme weather events.
Published Artificial reef designed by MIT engineers could protect marine life, reduce storm damage
(via sciencedaily.com) Original source Engineers designed an 'architected' reef that can mimic the wave-buffering effects of natural reefs while providing pockets for marine life. The sustainable and cost-saving structure could dissipate more than 95 percent of incoming wave energy using a small fraction of the material normally needed.
Published Understanding cattle grazing personalities may foster sustainable rangelands
(via sciencedaily.com) Original source New research finds that not all cattle are the same when it comes to grazing, and knowing that could lead to better animal health and range conditions.
Published A combination of approved drugs enhances the delivery of anti-bacterial medications to treat tuberculosis
(via sciencedaily.com) Original source Researchers have found that approved drugs that were originally shown to normalize blood vessels surrounding tumors (to improve drug delivery to cancer cells) can enhance the delivery of anti-microbial medications to kill tuberculosis bacteria residing in the lungs.
Published Climate change policies lose popularity when combined with pausing regulations or social justice
(via sciencedaily.com) Original source Legislators love bundling things together. It lets them accomplish more with less hassle and attempt to make legislation more appealing to a broader group. But a new study suggests that this can sometimes backfire. The authors found that pairing climate policies with other policies does not necessarily increase their popular appeal, and can actually reduce public support.
Published North American cities may see a major species turnover by the end of the century
(via sciencedaily.com) Original source Climate change may dramatically affect the animal species observed in North American cities, according to a new study.
Published Food matters: Healthy diets increase the economic and physical feasibility of 1.5°C
(via sciencedaily.com) Original source A global shift to a healthier, more sustainable diet could be a huge lever to limit global warming to 1.5 C, researchers find. The resulting reduction of greenhouse gas emissions would increase the available carbon budget compatible with limiting global warming to 1.5 C, and allow to achieve the same climate outcome with less carbon dioxide removal and less stringent CO2 emissions reductions in the energy system. This would also reduce emission prices, energy prices and food expenditures.
Published Land under water: What causes extreme flooding?
(via sciencedaily.com) Original source If rivers overflow their banks, the consequences can be devastating -- just like the catastrophic floods in North Rhine-Westphalia and Rhineland-Palatinate of 2021 showed. In order to limit flood damage and optimize flood risk assessment, we need to better understand what factors can lead to extreme forms of flooding and to what extent. Using methods of explainable machine learning, researchers have shown that floods are more extreme when several factors are involved in their development.
Published Sweet success: Sugarcane's complex genetic code cracked
(via sciencedaily.com) Original source Scientists created a highly accurate reference genome for one of the most important modern crops and found a rare example of how genes confer disease resistance in plants. Exploring sugarcane's genetic code could help researchers develop more resilient and productive crops, with implications for both sugar production and biofuels.
Published A solar cell you can bend and soak in water
(via sciencedaily.com) Original source Researchers have developed an organic photovoltaic film that is both waterproof and flexible, allowing a solar cell to be put onto clothes and still function correctly after being rained on or even washed.
Published Rock-wallaby bite size ‘packs a punch’
(via sciencedaily.com) Original source Australian rock-wallabies are 'little Napoleons' when it comes to compensating for small size, packing much more punch into their bite than larger relatives. Researchers made the discovery while investigating how two dwarf species of rock-wallaby are able to feed themselves on the same kinds of foods as their much larger cousins.
Published Scientists extract genetic secrets from 4,000-year-old teeth to illuminate the impact of changing human diets over the centuries
(via sciencedaily.com) Original source Researchers have recovered remarkably preserved microbiomes from two teeth dating back 4,000 years, found in an Irish limestone cave. Genetic analyses of these microbiomes reveal major changes in the oral microenvironment from the Bronze Age to today. The teeth both belonged to the same male individual and also provided a snapshot of his oral health.
