Published The 2022 Durban floods were the most catastrophic yet recorded in KwaZulu-Natal
(via sciencedaily.com) Original source Research shows flooding events in the province have doubled in the last century.
Published Cities will need more resilient electricity networks to cope with extreme weather
(via sciencedaily.com) Original source Dense urban areas amplify the effects of higher temperatures, due to the phenomenon of heat islands in cities. This makes cities more vulnerable to extreme climate events. Large investments in the electricity network will be necessary to cool us down during heatwaves and keep us warm during cold snaps, according to a new study.
Published Warm liquid spewing from Oregon seafloor comes from Cascadia fault, could offer clues to earthquake hazards
(via sciencedaily.com) Original source Oceanographers discovered warm, chemically distinct liquid shooting up from the seafloor about 50 miles off Newport. They named the unique underwater spring 'Pythia's Oasis.' Observations suggest the spring is sourced from water 2.5 miles beneath the seafloor at the plate boundary, regulating stress on the offshore subduction zone fault.
Published Family tree of 'boring' butterflies reveals they're anything but
(via sciencedaily.com) Original source Important species often get overlooked if they lack flashy colors or charismatic behavior. This is true of euptychiine butterflies, one of the most common insects in the Amazon Rainforest that have been largely ignored by scientists and naturalists throughout the 20th century. A new study pieces together the natural history of the group, in which males can look so unlike females, they've been repeatedly mistaken for separate species, diversity has been drastically underestimated, and more than 100 unnamed species are waiting on scientific description.
Published Early crop plants were more easily 'tamed'
(via sciencedaily.com) Original source Borrowing a page from what we know about animal behavior, archaeologists say that we should reassess our understanding of the process of plant domestication.
Published Scientists advocate for integration of biogeography and behavioral ecology to rapidly respond to biodiversity loss
(via sciencedaily.com) Original source An interdisciplinary team of researchers is advocating for convergent research that integrates the fields of biogeography and behavioral ecology to more rapidly respond to challenges associated with climate change and biodiversity loss.
Published Shutting down nuclear power could increase air pollution
(via sciencedaily.com) Original source A new study shows that if U.S. nuclear power plants are retired, the burning of coal, oil, and natural gas to fill the energy gap could cause more than 5,000 premature deaths.
Published Solar cells charging forward
(via sciencedaily.com) Original source An environmentally friendlier solution to solar cell production with enhanced performance utilizes PEDOT:PSS/silicon heterojunction solar cells. This hybrid type is made of organic-inorganic material, which could potentially ease the production process compared to conventional silicon-only solar cells. It avoids manufacturing solar cells in vacuums and high-temperature processes, which require large and expensive equipment and a great amount of time.
Published Rooting out how plants control nitrogen use
(via sciencedaily.com) Original source Nitrogen is such a crucial nutrient for plants that vast quantities of nitrogen-containing fertilizers are spread on farmlands worldwide. However, excess nitrogen in the soil and in drainage run-off into lakes and rivers causes serious ecological imbalances. A recent study has uncovered the regulatory mechanisms at work when plants utilize nitrogenous fertilizers in their roots, a positive step in the quest to generate crops that require less fertilizer while still producing the yields needed to feed the world.
Published Scientists show how we can anticipate rather than react to extinction in mammals
(via sciencedaily.com) Original source Most conservation efforts are reactive. Typically, a species must reach threatened status before action is taken to prevent extinction, such as establishing protected areas. A new study shows that we can use existing conservation data to predict which currently unthreatened species could become threatened and take proactive action to prevent their decline before it is too late.
Published Engineered plants produce sex perfume to trick pests and replace pesticides
(via sciencedaily.com) Original source Tobacco plants have been engineered to manufacture an alluring perfume of insect sex pheromones, which could be used to confuse would-be pests looking for love and reduce the need for harmful pesticides.
Published Scientists discover a way Earth's atmosphere cleans itself
(via sciencedaily.com) Original source Human activities emit many kinds of pollutants into the air, and without a molecule called hydroxide (OH), many of these pollutants would keep aggregating in the atmosphere.
Published Spike in major league home runs tied to climate change
(via sciencedaily.com) Original source A new study identifies the influence of climate change in the greater number of home runs in major league baseball in recent years. The researchers found that more than 500 home runs since 2010 can be attributed to warmer, thinner air caused by global warming, and that rising temperatures could account for 10% or more of home runs by 2100 if greenhouse gas emissions continue unabated. The researchers examined how the average number of home runs per year could rise for each major league ballpark with every 1-degree Celsius increase in the global average temperature.
Published Fully recyclable printed electronics ditch toxic chemicals for water
(via sciencedaily.com) Original source Engineers have produced fully recyclable printed electronics that replace the use of chemicals with water in the fabrication process. By bypassing the need for hazardous chemicals, the demonstration points down a path industry could follow to reduce its environmental footprint and human health risks.
Published Long-forgotten equation provides new tool for converting carbon dioxide
(via sciencedaily.com) Original source To manage atmospheric carbon dioxide and convert the gas into a useful product, scientists have dusted off an archaic -- now 120 years old -- electrochemical equation.
Published Sierra squirrels find their niche amid a changing climate
(via sciencedaily.com) Original source A new study of squirrels in California's Sierra Nevada mountains finds that climate is just one factor impacting where species make their homes in a changing world.
Published US forests face an unclear future with climate change
(via sciencedaily.com) Original source Climate change might compromise how permanently forests are able to store carbon and keep it out of the air. In a new study, researchers found that the regions most at risk to lose forest carbon through fire, climate stress or insect damage are those regions where many forest carbon offset projects have been set up. The authors assert that there's an urgent need to update these carbon offsets protocols and policies.
Published New pesticide exposure test developed to protect inexperienced cannabis farmers
(via sciencedaily.com) Original source Chemists created a more reliable, robust and efficient way to monitor pesticide exposure and help protect the health and safety of agricultural workers, especially for emerging sectors like the cannabis industry.
Published Newly discovered probiotic could protect Caribbean corals threatened by deadly, devastating disease
(via sciencedaily.com) Original source Researchers have discovered the first effective bacterial probiotic for treating and preventing stony coral tissue loss disease (SCTLD), a mysterious ailment that has devastated Florida's coral reefs since 2014 and is rapidly spreading throughout the Caribbean. The probiotic treatment provides an alternative to the use of the broad-spectrum antibiotic amoxicillin, which has so far been the only proven treatment for the disease but which runs the risk of promoting antibiotic-resistant bacteria.
Published Moving towards 3 degrees of warming -- the phasing out of coal is too slow
(via sciencedaily.com) Original source The use of coal power is not decreasing fast enough. The Paris Agreement's target of a maximum of 2 degrees of warming appear to be missed, and the world is moving towards a temperature increase of 2.5 -- 3 degrees. At the same time it is feasible to avoid higher warming.
