Published Solar batteries: New material makes it possible to simultaneously absorb light and store energy
(via sciencedaily.com) Researchers are making progress on the design of a solar battery made from an abundant, non-toxic and easily synthesized material composed of 2D carbon nitride.
Published Scientists vacuum animal DNA from air in a Danish forest
(via sciencedaily.com) Original source Over 60 animal species in three days. That is how many mammals, birds and amphibians researchers found DNA traces from in the air in a Danish forest. The results can pave the way for a new and innovative way of mapping biodiversity.
Published Self-healing plastic becomes biodegradable
(via sciencedaily.com) Original source Chemists develop mineral plastics with numerous positive properties from sustainable basic building blocks and, together with biologists, demonstrate the material's excellent microbiological degradability.
Published How to move communities away from flooding risks with minimal harm
(via sciencedaily.com) Original source As sea levels rise and flooding becomes more frequent, many countries are considering a controversial strategy: relocation of communities. A Stanford analysis of planned relocations around the world reveals a blueprint for positive outcomes.
Published Making renewable, infinitely recyclable plastics using bacteria
(via sciencedaily.com) Original source Scientists engineered microbes to make the ingredients for recyclable plastics -- replacing finite, polluting petrochemicals with sustainable alternatives. The new approach shows that renewable, recyclable plastics are not only possible, but also outperform those from petrochemicals.
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 Global wildlife trade risks altering evolutionary history and ecosystem function, study suggests
(via sciencedaily.com) Original source Some of the world's most distinct and ancient animal species, which play crucial roles in our planet's ecosystems, are exploited for the wildlife trade across large parts of the world, according to new research.
Published Genetic study reveals that a captive-bred population could save endangered crocodile from extinction
(via sciencedaily.com) Original source Performing a genetic evaluation on the largest captive-bred population of the critically endangered Orinoco crocodile, researchers have revealed that the population preserves much of its founder diversity and no inbreeding, making it suitable for implementing wild releases. Since this species is almost extinct in the wild, the news brings hope for the recovery of populations.
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 Forgotten tropical plants rediscovered after 100-plus years with the help of community science
(via sciencedaily.com) Original source Deep in the tropical Andes, a genus called Nasa harbored elusive and forgotten plant species. Through the collaborative efforts of botanists and citizen scientists on iNaturalist, these plants have been rediscovered after decades, some even after more than a century.
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.
