Closing critical gap in weather forecasting Posted: 07 Dec 2019 04:35 AM PST Scientists working on the next frontier of weather forecasting are hoping that weather conditions 3-to-4 weeks out will soon be as readily available as seven-day forecasts. Having this type of weather information--called subseasonal forecasts--in the hands of the public and emergency managers can provide the critical lead time necessary to prepare for natural hazards like heat waves or the next polar vortex. |
Dramatic health benefits following air pollution reduction Posted: 06 Dec 2019 02:36 PM PST Reductions in air pollution yielded fast and dramatic impacts on health-outcomes, as well as decreases in all-cause morbidity, according to new findings. |
Reduced soil tilling helps both soils and yields Posted: 06 Dec 2019 10:22 AM PST By monitoring crops through machine learning and satellite data, scientists have found farms that till the soil less can increase yields of corn and soybeans and improve the health of the soil -- a win-win for meeting growing food needs worldwide. |
Novel way to ID disease-resistance genes in chocolate-producing trees found Posted: 06 Dec 2019 10:22 AM PST Chocolate-producing cacao trees that are resistant to a major pathogen were identified by an international team of plant geneticists. The findings point the way for plant breeders to develop trees that are tolerant of the disease. |
How do you cultivate a healthy plant microbiome? Posted: 06 Dec 2019 07:01 AM PST Crops today never see their parents' microbiome, so how do they develop a leaf microbial community that's healthy and resistant to invasion by pathogens? Biologists sequenced the microbiomes of tomatoes through four generations and saw three-quarters of the bacteria disappear, leaving a core community that proved resistant to random invaders. The findings show it's possible to cultivate a robust plant microbiome, and suggests that probiotic additions could survive on crops, providing lasting benefits. |
Wildlife in tropics hardest hit by forests being broken up Posted: 05 Dec 2019 11:17 AM PST Tropical species are six times more sensitive to forests being broken up for logging or farming than temperate species, says new research. |
Using green products leads to a warm glow in shoppers Posted: 05 Dec 2019 10:06 AM PST A new article suggests that spending some of that money on green products might make consumers feel quite a bit better about their purchases. The study looks at the so-called ''greenconsumption effect'' -- how using a green product creates a ''warm glow'' feeling in users -- and what it means for retailers in an increasingly eco-conscious marketplace. |
A solution for cleaning up PFAS, one of the world's most intractable pollutants Posted: 05 Dec 2019 10:06 AM PST Engineers have developed a treatment train for a PFAS compound called HFPO-Dimer Acid, also known by its trade name, GenX. |
Prenatal and early life exposure to multiple air pollutants increases odds of toddler allergies Posted: 05 Dec 2019 10:05 AM PST A new article shows a significant association between multiple prenatal and early life exposures to indoor pollutants and the degree of allergic sensitivity in 2-year-olds. |
Microwave treatment is an inexpensive way to clean heavy metals from treated sewage Posted: 05 Dec 2019 10:05 AM PST A team of researchers studying new methods to remove toxic heavy metals from biosolids -- the solid waste left over after sewage treatment -- found the key is a brief spin through a microwave. |
Whales may owe their efficient digestion to millions of tiny microbes Posted: 05 Dec 2019 10:05 AM PST A study shows that the microbial communities inside whales may play an important role in the digestion of one of the ocean's most abundant carbon-rich lipids, known as a wax ester. |
Your food may help make stickier, safer glues for laptops, packaging, furniture Posted: 05 Dec 2019 08:31 AM PST A group of scientists has taken inspiration from the field, kitchen and the ocean to create strong glues. |
First 'lab in a field' experiment reveals a sunnier side of climate change Posted: 05 Dec 2019 08:31 AM PST Pioneering experiments using heated field plots to test the responses of crops to temperature have revealed an unexpected plus side of climate change for farmers. |
Multiple correlations between brain complexity and locomotion pattern in vertebrates Posted: 05 Dec 2019 07:33 AM PST Researchers have uncovered multi-level relationships between locomotion - the ways animals move - and brain architecture, using high-definition 3D models of lizard and snake brains. |
Less rice, more nutritious crops will enhance India's food supply Posted: 04 Dec 2019 02:04 PM PST India can sustainably enhance its food supply if its farmers plant less rice and more nutritious and environmentally-friendly crops, including finger millet, pearl millet, and sorghum, according to a new study. |
How to improve water quality in Europe Posted: 03 Dec 2019 07:20 AM PST Toxic substances from agriculture, industry and households endanger water quality in Europe -- and by extension, ecosystems and human health. As part of the SOLUTIONS project, over 100 international scientists have developed methods and practical solutions for identifying pollutants and assessing the risks posed by chemical cocktails. This is intended to help reduce pollution in water resources. Researchers have described how politicians can implement these scientific results in 15 policy briefs. |
Genomic gymnastics help sorghum plant survive drought Posted: 03 Dec 2019 06:10 AM PST A new study provides the first detailed look at how the sorghum plant exercises exquisite control over its genome -- switching some genes on and some genes off at the first sign of water scarcity, and again when water returns -- to survive when its surroundings turn harsh and arid. |
