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 Soft optical fibers block pain while moving and stretching with the body
(via sciencedaily.com) Original source New soft, implantable fibers can deliver light to major nerves through the body. They are an experimental tool for scientists to explore the causes and potential treatments for peripheral nerve disorders in animal models.
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 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.
Published Researchers: There is a need for more accurate accounting of nitrous oxide from agricultural crop residues
(via sciencedaily.com) Original source According to researchers, there is a need for changing the way of accounting greenhouse gases from agriculture. The current inventory of nitrous oxide from plant residues relies solely on the amount of nitrogen in the residues, while crucial factors such as the degradability of plant residues are not included. According to the researchers, this leads to misleading inventories, which also misrepresents possible mitigation measures.
Published Potential for 110% electricity increases in U. S. urban buildings
(via sciencedaily.com) Original source A research study tackled the critical issue of how city-scale building energy consumption in urban environments will evolve under the influence of climate change.
Published Researchers study one of the world's darkest rivers
(via sciencedaily.com) Original source They set out to study the Congo Basin's carbon cycle and in the process have become aware of one of the world's darkest blackwater rivers: the Ruki. In the first study on this major jungle river, an international research team explains how this blackness comes about and what it says about the river system's carbon balance.
Published New insights into the genetics of the common octopus: Genome at the chromosome level decoded
(via sciencedaily.com) Original source Octopuses are fascinating animals -- and serve as important model organisms in neuroscience, cognition research and developmental biology. To gain a deeper understanding of their biology and evolutionary history, validated data on the composition of their genome is needed, which has been lacking until now. Scientists have now been able to close this gap and, in a new study, determined impressive figures: 2.8 billion base pairs -- organized in 30 chromosomes. What sounds so simple is the result of complex, computer-assisted genome analyses and comparisons with the genomes of other cephalopod species.
Published Greener neighborhoods can protect us -- at the cellular level
(via sciencedaily.com) Original source A new study finds that greenspace -- the vegetation in a neighborhood's yards, parks and public spaces -- has a positive impact on a key genetic marker associated with exposure to stress. However, the study also finds that the positive impact of greenspace isn't enough to compensate for other environmental challenges, such as air pollution.
Published Germicidal UV lights could be producing indoor air pollutants, study finds
(via sciencedaily.com) Original source While useful for killing pathogens including SARS-CoV-2, 222-nanometer UV lights may produce harmful compounds in indoor spaces, and should be used with ventilation, researchers have found.
Published How to build greener data centers? Scientists say crank up the heat
(via sciencedaily.com) Original source Colder is not always better for energy-hungry data centers, especially when it comes to their power bills. A new analysis says that keeping the centers at 41°C, or around 105°F, could save up to 56% in cooling costs worldwide. The study proposes new temperature guidelines that may help develop and manage more efficient data centers and IT servers in the future.
Published Unlocking the secrets of cell behavior on soft substrates: A paradigm shift in mechanobiology
(via sciencedaily.com) Original source A research group has developed a new method for studying how cancer cells function in softer and stiffer tissue environments. This insight challenges the existing paradigm, opening up new possibilities for research in cancer biology and tissue engineering.
Published Subalpine forests in the Northern Rockies are fire resilient--for now
(via sciencedaily.com) Original source Using lake sediment cores, scientists determined how these subalpine ecosystems recovered after 4,800 years of fire.
Published New recipe for efficient, environmentally friendly battery recycling
(via sciencedaily.com) Original source Researchers are now presenting a new and efficient way to recycle metals from spent electric car batteries. The method allows recovery of 100 per cent of the aluminum and 98 per cent of the lithium in electric car batteries. At the same time, the loss of valuable raw materials such as nickel, cobalt and manganese is minimized. No expensive or harmful chemicals are required in the process because the researchers use oxalic acid -- an organic acid that can be found in the plant kingdom.
Published How to help save plants from extinction
(via sciencedaily.com) Original source Now is the time to identify the conditions that cause plants to die. Doing so will allow us to better protect plants by choosing conservation targets more strategically, botanists argue.
Published Ocean circulation, ice melt and increasing tourism could all be contributing to Arctic microplastics
(via sciencedaily.com) Original source Scientists measured microplastic concentrations in the highly productive Barents Sea and suggest that ocean circulation, ice melt, tourism, inadequate waste management, shipping and fishing are all likely contributors.
Published Research finds water quality in Gulf of Mexico improves when adding social costs to carbon emissions
(via sciencedaily.com) Original source Researchers took a closer look at what would happen to agriculture if there was an extra cost, or so-called social cost, added to fossil fuels, which are essential for making fertilizer used in farming. They found that while CO2 emissions would decline by as much as 50%, the cost of fertilizer would rise leading to a significant benefit on water quality by lessening fertilizer runoff contributing to the Gulf of Mexico's dead zone.
Published World may have crossed solar power 'tipping point'
(via sciencedaily.com) Original source The world may have crossed a 'tipping point' that will inevitably make solar power our main source of energy, new research suggests.
