Published Study suggests even more reasons to eat your fiber
(via sciencedaily.com) Original source Health professionals have long praised the benefits of insoluble fiber for bowel regularity and overall health. New research suggests even more reasons we should be prioritizing fiber in our regular diets. Researchers found that each plant source of insoluble fiber contains unique bioactives -- compounds that have been linked to lower incidence of cardiovascular disease, cancer and Type 2 diabetes -- offering potential health benefits beyond those of the fiber itself.
Published Raining cats and dogs: Global precipitation patterns a driver for animal diversity
(via sciencedaily.com) Original source A team has identified several factors to help answer a fundamental ecological question: why is there a ridiculous abundance of species some places on earth and a scarcity in others? What factors, exactly, drive animal diversity? They discovered that what an animal eats (and how that interacts with climate) shapes Earth's diversity.
Published Climate report: 'Uncharted territory' imperils life on Earth
(via sciencedaily.com) Original source An international coalition of climate scientists says that the Earth's vital signs have worsened beyond anything humans have yet seen, to the point that life on the planet is imperiled.
Published Scientists develop new method to create stable, efficient next-gen solar cells
(via sciencedaily.com) Original source Next-generation solar materials are cheaper and more sustainable to produce than traditional silicon solar cells, but hurdles remain in making the devices durable enough to withstand real-world conditions. A new technique could simplify the development of efficient and stable perovskite solar cells, named for their unique crystalline structure that excels at absorbing visible light.
Published Certain per- and polyfluoroalkyl 'forever chemicals' identified as potential risk factor for thyroid cancer
(via sciencedaily.com) Original source Researchers have discovered a link between certain per- and polyfluoroalkyl substances (PFAS) and an increased risk for thyroid cancer.
Published Climate is increasing risk of high toxin concentrations in Northern US lakes
(via sciencedaily.com) Original source As climate change warms the Earth, higher-latitude regions will be at greater risk for toxins produced by algal blooms, according to new research. The findings identify water temperatures of 20 to 25 degrees Celsius (68 to 77 degrees Fahrenheit) as being at the greatest risk for developing dangerous levels of a common algae-produced toxin called microcystin.
Published Increased West Antarctic Ice Sheet melting 'unavoidable'
(via sciencedaily.com) Original source The West Antarctic Ice Sheet will continue to increase its rate of melting over the rest of the century, no matter how much we reduce fossil fuel use, according to new research. A substantial acceleration in ice melting likely cannot now be avoided, which implies that Antarctica's contribution to sea level rise could increase rapidly over the coming decades.
Published Does urbanization trigger plant evolution?
(via sciencedaily.com) Original source Urban environments have become hotspots for understanding how rapid evolution occurs in response to extreme environmental changes. These habitats exert selective pressures on resident organisms that impact their evolutionary trajectories. Recently, researchers investigated how the creeping woodsorrel plant might adapt in response to elevated temperatures that result from urbanization. Understanding these effects can help predict evolutionary traits to manage plant evolution in the face of shifting climatic conditions.
Published Land use: Producing more food and storing more carbon
(via sciencedaily.com) Original source Doubling food production, saving water, and increasing carbon storage capacity -- this may sound paradoxical, but would be theoretically feasible considering the biophysical potential of the Earth. Reaching this goal, however, would require a radical spatial reorganization of land use.
Published Pivotal breakthrough in adapting perovskite solar cells for renewable energy
(via sciencedaily.com) Original source A huge step forward in the evolution of perovskite solar cells will have significant implications for renewable energy development.
Published New extremes in stratospheric water vapor
(via sciencedaily.com) Original source The focus of new research was to determine how deep, how much and how frequently water in the stratosphere was being increased by thunderstorms.
Published El Niño's changing patterns: Human influence on natural variability
(via sciencedaily.com) Original source Two recent scientific studies provide new insights into Earth's climate dynamics, with a particular focus on the El Niño phenomenon. The results show how El Niño responds to natural factors over extended periods, while highlighting the increasing role of human activities in shaping this climatic phenomenon in the modern era.
Published Scientists discover deepest known evidence of coral reef bleaching
(via sciencedaily.com) Original source Scientists have discovered the deepest known evidence of coral reef bleaching, more than 90 metres below the surface of the Indian Ocean. Identified during a research cruise, the damage to the deeper reefs in the Central Indian Ocean has been attributed to significant changes in the region's ocean temperature caused by the Indian Ocean Dipole. The researchers have also warned such incidences are only likely to increase as a result of present and future climate change.
Published New study finds 50-year trend in hurricane escalation linked to climate change
(via sciencedaily.com) Original source New research by climate scientists indicates that there have been great changes to Atlantic hurricanes in just the past 50 years, with storms developing and strengthening faster.
Published Cut emissions and improve farming to protect wilderness
(via sciencedaily.com) Original source Humanity must cut carbon emissions and use farmland more efficiently to protect our planet's remaining wilderness, new research shows.
Published Urgent action needed to address climate change threats to coastal areas
(via sciencedaily.com) Original source Global coastal adaptations are 'incremental in scale', short-sighted and inadequate to address the root causes of vulnerability to climate change, according to an international team of researchers.
Published California supervolcano is cooling off but may still cause quakes
(via sciencedaily.com) Original source New high-resolution images of the Long Valley Caldera indicate that the subsurface environment is cooling off, releasing gas and fluids that contribute to seismic activity.
Published Biodegradable plastics still damaging to fish
(via sciencedaily.com) Original source Biodegradable plastics may not be the solution to plastic pollution many hoped for, with a new study showing they are still harmful to fish.
Published Drought conditions expose rivers to hotter water temperatures
(via sciencedaily.com) Original source A new study reveals how reduced water flows and rising atmospheric temperatures are set to heat our rivers -- creating major challenges for aquatic life, ecosystems, and society.
Published Reef-devouring predator survives coral bleaching and feasts on the survivors
(via sciencedaily.com) Original source The crown-of-thorns starfish is nature's ultimate coral predator that has a circle of life perfectly adapted to warming waters.
