Published Deer are expanding north, and that's not good for caribou
(via sciencedaily.com) Original source In the boreal forest of Western Canada, researchers have considered that both changing climate and increased habitat alteration have enabled deer to push farther north.
Published How do birds flock? Researchers do the math to reveal previously unknown aerodynamic phenomenon
(via sciencedaily.com) Original source How do birds fly in a coordinated and seemingly effortless fashion? Part of the answer lies in precise, and previously unknown, aerodynamic interactions, reports a team of mathematicians. Its breakthrough broadens our understanding of wildlife, including fish, who move in schools, and could have applications in transportation and energy.
Published Human activities have an intense impact on Earth's deep subsurface fluid flow
(via sciencedaily.com) Original source Hydrologists predict human-induced underground fluid fluxes to rise with climate change mitigation strategies like carbon sequestration.
Published Artificial intelligence helps scientists engineer plants to fight climate change
(via sciencedaily.com) Original source Scientists are using artificial intelligence software to analyze plant root systems, laying out a protocol that can be applied to gather data on crop and model plant phenotypes (physical characteristics) more efficiently and with equal or greater accuracy than existing methods.
Published How light can vaporize water without the need for heat
(via sciencedaily.com) Original source Researchers discovered that light can cause evaporation of water from a surface without the need for heat. This 'photomolecular effect' could be important for understanding climate change and for improving some industrial processes.
Published Positive perceptions of solar projects
(via sciencedaily.com) Original source A new survey has found that for residents living within three miles of a large-scale solar development, positive attitudes outnumbered negative attitudes by almost a 3-to-1 margin. Researchers surveyed almost 1,000 residents living near solar projects.
Published Hurricanes jeopardize carbon-storing New England forests
(via sciencedaily.com) Original source Many American companies are relying on carbon offsets to reduce their carbon footprint, especially those who have pledged to achieve 'net-zero emissions.' Sequestering carbon in forests is an example of a nature-based solution that is being used to address climate change, but a new study suggests that hurricanes could pose a risk. The results show that a single hurricane may wipe out 5% to 10% of total above-ground forest carbon, through tree damage, in New England.
Published Can climate change accelerate transmission of malaria? Pioneering research sheds light on impacts of temperature
(via sciencedaily.com) Original source A groundbreaking study combined novel experimental data within an innovative modeling framework to examine how temperature might affect transmission risk of malaria in different environments in Africa.
Published Diversity and productivity go branch-in-branch
(via sciencedaily.com) Original source Researchers found that forests with higher trait diversity not only adapt better to climate change but may also thrive. The study unveiled how tree functional trait diversity plays a pivotal role in mitigating climate warming. In the face of environmental stress, these diverse trees have been shown to maintain higher productivity levels, in contrast to monoculture forests.
Published Nanofibers rid water of hazardous dyes
(via sciencedaily.com) Original source A special nanostructure has been developed to filter a widespread class of harmful dyes from water. A crucial component is a material that is considered waste: used cellulose, for example in the form of cleaning cloths or paper cups. The cellulose is utilized to coat a fine nano-fabric to create an efficient filter for polluted water.
Published Securing competitiveness of energy-intensive industries through relocation: The pulling power of renewables
(via sciencedaily.com) Original source Countries with limited potential for renewables could save up to 20 percent of costs for green steel and up to 40 percent for green chemicals from green hydrogen if they relocated their energy-intensive production and would import from countries where renewable energy is cheaper.
Published This salt battery harvests osmotic energy where the river meets the sea
(via sciencedaily.com) Original source Estuaries -- where freshwater rivers meet the salty sea -- are great locations for birdwatching and kayaking. In these areas, waters containing different salt concentrations mix and may be sources of sustainable, 'blue' osmotic energy. Researchers report creating a semipermeable membrane that harvests osmotic energy from salt gradients and converts it to electricity. The new design had an output power density more than two times higher than commercial membranes in lab demonstrations.
Published Modeling broader effects of wildfires in Siberia
(via sciencedaily.com) Original source As wildfires in Siberia become more common, global climate modeling estimates significant impacts on climate, air quality, health, and economies in East Asia and across the northern hemisphere.
Published Researchers find oldest undisputed evidence of Earth's magnetic field
(via sciencedaily.com) Original source A new study has recovered a 3.7-billion-year-old record of Earth's magnetic field, and found that it appears remarkably similar to the field surrounding Earth today.
Published Shoreline model predicts long-term future of storm protection and sea-level rise
(via sciencedaily.com) Original source Researchers have created a coastal evolution model to analyze how coastal management activities on barrier islands, meant to adapt to sea-level rise, can disrupt natural processes that are keeping the barrier islands above water. Replenishing beaches and clearing over-washed roads may not be the best long term strategy.
Published High-resolution lidar sees birth zone of cloud droplets
(via sciencedaily.com) Original source Scientists demonstrated the first-ever remote observations of the fine-scale structure at the base of clouds. The results show that the air-cloud interface is a transition zone where aerosol particles suspended in Earth's atmosphere give rise to the droplets that ultimately form clouds. The research will enable scientists to gain insight into how changes in atmospheric aerosol levels could affect clouds and climate.
Published Eruption of mega-magnetic star lights up nearby galaxy
(via sciencedaily.com) Original source While ESA's satellite INTEGRAL was observing the sky, it spotted a burst of gamma-rays -- high-energy photons -- coming from the nearby galaxy M82. Only a few hours later, ESA's XMM-Newton X-ray space telescope searched for an afterglow from the explosion but found none. An international team realized that the burst must have been an extra-galactic flare from a magnetar, a young neutron star with an exceptionally strong magnetic field.
Published Frog species evolved rapidly in response to road salts
(via sciencedaily.com) Original source When we think of evolution, we think of a process that happens over hundreds or thousands of years. In research recently published, a species of frog that has evolved over the course of merely 25 years. The adaptation was spurred on by something many assume is innocuous: salt.
Published Critical minerals recovery from electronic waste
(via sciencedaily.com) Original source A nontoxic separation process recovers critical minerals from electronic scrap waste.
Published Asian monsoon lofts ozone-depleting substances to stratosphere
(via sciencedaily.com) Original source Powerful monsoon winds, strengthened by a warming climate, are lofting unexpectedly large quantities of ozone-depleting substances high into the atmosphere over East Asia, according to new research. The study found that the East Asian Monsoon delivers more than twice the concentration of very short-lived ozone-depleting substances into the upper troposphere and lower stratosphere than previously reported.
