Published Mashed up purple marine bacteria makes an excellent eco-friendly fertilizer
(via sciencedaily.com) Original source New research reports that biomass made from the purple photosynthetic marine bacterium Rhodovulum sulfidophilum is an excellent nitrogen fertilizer. The biomass fertilizer proved to be just as effective as common inorganic synthetic fertilizers but avoids several side effects that harm the environment, making it an eco-friendly alternative.
Published Carbon dioxide's heavy stamp on temperature: Doubling CO2 may mean 7 to 14 degree increase
(via sciencedaily.com) Original source A doubling of the amount of CO2 in the atmosphere could cause an increase in the average temperature on earth from 7 to even a maximum of 14 degrees. That is shown in the analysis of sediments from the Pacific Ocean off the coast of California.
Published Boosting biodiversity without hurting local economies
(via sciencedaily.com) Original source Protected areas, like nature reserves, can conserve biodiversity without harming local economic growth, countering a common belief that conservation restricts development. A new study outlines what is needed for conservation to benefit both nature and people.
Published Human activity: A double-edged sword in the face of drought
(via sciencedaily.com) Original source A professor analyzes the conflicting impacts of human activities on extreme spring droughts.
Published Promise green hydrogen may not always be fulfilled
(via sciencedaily.com) Original source Green hydrogen often, but certainly not always, leads to CO2 gains.
Published Up to 30 percent more time: Climate change makes it harder for women to collect water, study finds
(via sciencedaily.com) Original source By 2050, climate change could increase the amount of time women in households without running water spend collecting water by up to 30 percent on global average, according to a new study. In regions of South America and Southeast Asia, the time spent collecting water could double due to higher temperatures. Scientists estimate the large welfare losses that could result from climate impacts and highlights how women are particularly vulnerable to changing future climate conditions.
Published Membrane protein analogues could accelerate drug discovery
(via sciencedaily.com) Original source Researchers have created a deep learning pipeline for designing soluble analogues of key protein structures used in pharmaceutical development, sidestepping the prohibitive cost of extracting these proteins from cell membranes.
Published Restoring the Great Salt Lake would have environmental justice as well as ecological benefits
(via sciencedaily.com) Original source Inland seas around the world are drying up due to increasing human water use and accelerating climate change, and their desiccation is releasing harmful dust that pollutes the surrounding areas during acute dust storms. Using the Great Salt Lake in Utah as a case study, researchers show that dust exposure was highest among Pacific Islanders and Hispanic people and lower in white people compared to all other racial/ethnic groups, and higher for individuals without a high school diploma. Restoring the lake would benefit everyone in the vicinity by reducing dust exposure, and it would also decrease the disparities in exposure between different racial/ethnic and socioeconomic groups.
Published Changing climate will make home feel like somewhere else
(via sciencedaily.com) Original source The impacts of climate change are being felt all over the world, but how will it impact how your hometown feels? An interactive web application allows users to search 40,581 places and 5,323 metro areas around the globe to match the expected future climate in each city with the current climate of another location, providing a relatable picture of what is likely in store.
Published Climate models underestimate carbon cycling through plants
(via sciencedaily.com) Original source The carbon stored globally by plants is shorter-lived and more vulnerable to climate change than previously thought, according to a new study.
Published At least one in four US residential yards exceed new EPA lead soil level guideline
(via sciencedaily.com) Original source Roughly one in four U.S. households have soil exceeding the new U.S. Environmental Protection Agency's lead screening levels of 200 parts per million (ppm), halved from the previous level of 400 ppm, a new study found. For households with exposure from multiple sources, the EPA lowered the guidance to 100 ppm; nearly 40% of households exceed that level, the study also found.
Published Non-native plants and animals expanding ranges 100 times faster than native species
(via sciencedaily.com) Original source An international team of scientists has recently found that non-native species are expanding their ranges many orders of magnitude faster than native ones, in large part due to inadvertent human help. Even seemingly sedentary non-native plants are moving at three times the speed of their native counterparts in a race where, because of the rapid pace of climate change and its effect on habitat, speed matters. To survive, plants and animals need to be shifting their ranges by 3.25 kilometers per year just to keep up with the increasing temperatures and associated climactic shifts -- a speed that native species cannot manage without human help.
Published Blessing in disguise: Mycoviruses enhance fungicide effectiveness against plant pathogens
(via sciencedaily.com) Original source Researchers discovered that mycoviruses, or oomycete viruses, can increase the sensitivity of plant pathogenic oomycete to fungicides like metalaxyl. Their findings suggest greater potential for mycoviruses in biocontrol and contributing to sustainable agriculture.
Published When in drought: Researchers map which parts of the Amazon are most vulnerable to climate change
(via sciencedaily.com) Original source Some areas of the Amazon rainforest are more resilient to drought than others, new research shows. But if not managed carefully, we could 'threaten the integrity of the whole system,' researchers say.
Published Mirror-image chemicals may revolutionize drug delivery
(via sciencedaily.com) Original source More than 130 years after cyclodextrins were first discovered and reported, a team of scientists has created chemical mirror images of these complex carbohydrates in the laboratory. This discovery may revolutionize how medications are delivered to patients.
Published Tight-knit communities can prevent environmental progress
(via sciencedaily.com) Original source New research indicates that strong community bonds could hinder rather than help environmental initiatives.
Published Large wildfires create weather that favors more fire
(via sciencedaily.com) Original source A new study shows soot from large wildfires in California traps sunlight, making days warmer and drier than they ought to be.
Published Advanced artificial intelligence: A revolution for sustainable agriculture
(via sciencedaily.com) Original source The rise of advanced artificial intelligence (edge AI) could well mark the beginning of a new era for sustainable agriculture. A recent study proposes a roadmap for integrating this technology into farming practices. The aim? To improve the efficiency, quality and safety of agricultural production, while addressing a range of environmental, social and economic challenges.
Published New material puts eco-friendly methanol conversion within reach
(via sciencedaily.com) Original source Researchers have developed innovative, eco-friendly quantum materials that can drive the transformation of methanol into ethylene glycol. This discovery opens up new possibilities for using eco-friendly materials in photocatalysis, paving the way for sustainable chemical production.
Published Custom-made molecules designed to be invisible while absorbing near-infrared light
(via sciencedaily.com) Original source Researchers used theoretical calculations assessing electron orbital symmetry to synthesize new molecule designed to be both transparent and colorless while absorbing near-infrared light. This compound demonstrates the first systematic approach to producing such materials and have applications in advanced electronics. This compound also shows semiconducting properties.
