Published New study reveals that tree species diversity increases spider density
(via sciencedaily.com) Original source The link between tree diversity and spider populations can help homeowners and other land managers better plan tree plantings to naturally mitigate the effects of climate change.
Published New insights into the origin of the Indo-European languages
(via sciencedaily.com) Original source An international team of linguists and geneticists has achieved a significant breakthrough in our understanding of the origins of Indo-European, a family of languages spoken by nearly half of the world's population.
Published New research method determines health impacts of heat and air quality
(via sciencedaily.com) Original source The planet experienced the hottest day on record earlier this month and climate projections estimate the intensity of heat waves and poor air quality will increase and continue to cause severe impacts. Researchers have refined and expanded a method of data collection to assess their health impacts.
Published Climate change threatens 771 endangered plant and lichen species
(via sciencedaily.com) Original source All plants and lichens listed as endangered under the Endangered Species Act are sensitive to climate change but there are few plans in place to address this threat directly, according to new research.
Published Delaying methane mitigation increases risk of breaching Paris Agreement climate goal, study finds
(via sciencedaily.com) Original source A new study shows that efforts to reduce methane emissions are needed immediately if we are to meet global climate change goals. A key element of the 2015 Paris Agreement, a legally binding international treaty on climate change, is the commitment to limit average global temperatures increases to well below 2°C above pre-industrial levels, and pursue efforts to limit global warming to 1.5°C above pre-industrial levels. This requires reaching net-zero CO2 emissions by or around 2050 -- and deep reductions in methane and other emissions.
Published Earlier and earlier high-Arctic spring replaced by 'extreme year-to-year variation'
(via sciencedaily.com) Original source About 15 years ago, researchers reported that the timing of spring in high-Arctic Greenland had advanced at some of the fastest rates of change ever seen anywhere in the world. But, according to new evidence, that earlier pattern has since been completely erased. Instead of coming earlier and earlier, it seems the timing of Arctic spring is now driven by tremendous climate variability with drastic differences from one year to the next.
Published Arctic terns may navigate climate dangers
(via sciencedaily.com) Original source Arctic terns -- which fly on the longest migrations of any animal on Earth -- may be able to navigate the dangers posed by climate change, new research suggests.
Published Soil microbes help plants cope with drought, but not how scientists thought
(via sciencedaily.com) Original source In a multi-generation experiment, researchers found microbes helped plants cope with drought, but not in response to plants' cries for help. Instead, the environment itself selected for drought-tolerant microbes. And while those hardy microbes were doing their thing, they just happened to make plants more drought-tolerant, too.
Published Gloomy climate calculation: Scientists predict a collapse of the Atlantic ocean current to happen mid-century
(via sciencedaily.com) Original source Important ocean currents that redistribute heat, cold and precipitation between the tropics and the northernmost parts of the Atlantic region will shut down around the year 2060 if current greenhouse gas emissions persist. This is the conclusion based on new calculations that contradict the latest report from the IPCC.
Published Researchers recover vital resources from wastewater sludge
(via sciencedaily.com) Original source If you were ever to see sewage sludge up close, you might be hard-pressed to find any redeemable value; however, researchers now see it another way.
Published Dynamic pricing superior to organic waste bans in preventing climate change
(via sciencedaily.com) Original source While composting and organic waste ban policies are gaining popularity across the United States, a new study finds dynamic pricing could be the most effective way for grocery chains to keep perishables out of landfills, reducing food waste by 21% or more.
Published Improving recyclable waste classification with laser-induced breakdown spectroscopy
(via sciencedaily.com) Original source Delving into the intricacies of waste management, researchers explore the application of laser-induced breakdown spectroscopy technology for the identification and classification of recyclable waste. They collected and analyzed the spectra of 80 recyclable waste samples, classifying them into paper, plastic, glass, metal, textile, and wood based on LIBS spectra. This crucial step toward waste management optimization demonstrates a significant stride toward improving environmental sustainability and promoting resource reuse.
Published New robot boosts solar energy research
(via sciencedaily.com) Original source Researchers have created a robot capable of conducting experiments more efficiently and sustainably to develop a range of new semiconductor materials with desirable attributes. The researchers have already demonstrated that the new technology, called RoboMapper, can rapidly identify new perovskite materials with improved stability and solar cell efficiency.
Published Risk of fatal heart attack may double in heat wave and high fine particulate pollution days
(via sciencedaily.com) Original source An analysis of more than 202,000 heart attack deaths between 2015-2020 in a single Chinese province found that days that had extreme heat, extreme cold or high levels of fine particulate matter (PM2.5) air pollution were significantly associated with the risk of death from a heart attack, especially in women and older adults.
Published Study links cadmium levels in women's urine to endometriosis
(via sciencedaily.com) Original source Women with a history of endometriosis had higher concentrations of cadmium in their urine compared to those without that diagnosis, according to a new study that suggests the toxic metal could be linked to the development of endometriosis.
Published Advancing chemical recycling of waste plastics
(via sciencedaily.com) Original source New research focuses on optimizing a promising technology called pyrolysis, which can chemically recycle waste plastics into more valuable chemicals.
Published Study improves understanding of how bacteria benefit plant growth
(via sciencedaily.com) Original source Scientists have found that competition between strains of beneficial bacteria in the soil degrades the service that the bacteria provide to their hosts.
Published Renewable solar energy can help purify water, the environment
(via sciencedaily.com) Chemists have demonstrated that water remediation can be powered in part -- and perhaps even exclusively -- by renewable energy sources.
Published Biosurfactants might offer an environmentally friendly solution for tackling oil spills
(via sciencedaily.com) Original source Can biosurfactants increase microbiological oil degradation in North Sea seawater? An international research team has been exploring this question and the results have revealed the potential for a more effective and environmentally friendly oil spill response.
Published Nature inspires breakthrough achievement: Hazard-free production of fluorochemicals
(via sciencedaily.com) Original source A team of chemists have developed an entirely new method for generating critically important fluorochemicals that bypasses the hazardous product hydrogen fluoride (HF) gas. The findings could achieve an immense impact in improving the safety and carbon footprint of a growing global industry.
