Herbal remedy for radioactive soil contamination
A herb that grows abundantly in coastal areas can be used to rid the soil around nuclear plants of cesium, a radioactive by-product of reactors, says a new study......»»
Researchers develop high-sensitivity technique to detect mercury in soil
Environmental pollution by heavy metals is a major social problem. Among these metals, mercury (Hg) is strictly controlled due to its high toxicity. Focusing on soil, which is closely related to our daily lives, the environmental standard for mercury.....»»
US farmers want to adapt to climate change, but crop insurance won"t let them
In Kansas, where a prolonged drought has killed crops and eroded the soil, Gail Fuller's farm is like an oasis. Sheep, cows and chickens graze freely on crops and vegetation in a paradisiacal mess......»»
Inspired by cicada wings, researchers study the insects" antimicrobial properties to develop antibacterial surfaces
Trillions of periodical cicadas—several species of the genus Magicicada that emerge every 13 or 17 years—broke soil across the Eastern U.S. this summer. News outlets likened the event to Armageddon, an apocalypse or an invasion. But what about us.....»»
Are chemicals still spreading near Placer County missile site in Northern California? New probe data show the latest
The most recent data collected by the U.S. Army Corps of Engineers at the Titan-1 missile silo site in Placer County found that despite longstanding concerns, new soil vapor monitoring probes closest to homes in the Sun City Lincoln Hills development.....»»
Electrothermal mineralization process offers more environmentally friendly, cost-effective method for soil remediation
Rice University chemist James Tour has led a research team to develop a rapid electrothermal mineralization (REM) process, which in seconds can remediate the accumulation of synthetic chemicals that can contaminate soil and the environment. The study.....»»
Team develops a technique to detect nutrients in soil faster and more affordably
Every year, Missouri farmers lose millions of dollars in valuable nutrients that wash away into rivers and lakes. These nutrients—nitrates and phosphates found in fertilizers—are crucial for plant growth, but they wreak havoc on aquatic life when.....»»
Elevated levels of antibiotic resistance genes should be considered a new factor of global change, researchers say
Human-caused global change is a complex phenomenon comprising many factors such as climate change, environmental contamination with chemicals, microplastics, light pollution, and invasive plants. One of the main tasks of global change biology is to i.....»»
Environmental groups ask feds to take over Georgia"s coal ash program
A handful of environmental groups filed a petition July 18 asking the U.S. Environmental Protection Agency (EPA) to claw back oversight of the disposal of Georgia's toxic coal ash from state regulators, citing concerns over groundwater contamination......»»
Electrified membranes with carbon nanotubes offer faster nitrate removal in drinking water
Nitrate contamination in water has long presented threats to the environment and human health. Now, Yale researchers have developed an efficient and effective way to remove it......»»
Rhythmic gene expression in plants is crucial for symbiosis with nutrient-providing bacteria, study finds
Legumes thrive in low-nitrogen environments by partnering with rhizobia, soil bacteria that convert atmospheric nitrogen into ammonium, a usable form for the plants. These beneficial bacteria are housed in root nodules formed on legume roots......»»
Study reveals key gene protecting plants from harmful metals in soil
The negative impact of human activity on Earth doesn't just affect our planet's atmosphere—it goes much deeper, into its soils. For instance, excessive application of manure or sewage sludge can increase heavy metal concentrations in agricultural l.....»»
Unraveling the DNA mystique of Saposhnikovia divaricata: New horizons in herbal medicine
Scientists have decoded the genetic blueprint of Saposhnikovia divaricata, a traditional medicinal herb. Their research provides a detailed genome sequence, shedding light on the plant's evolutionary adaptations and the genetic foundations of its the.....»»
Study highlights the benefits of mixing cover crops
A University of Kentucky study titled "Productivity benefits of cereal-legume cover crop mixtures under variable soil nitrogen and termination times" suggests that mixing cover crops is a beneficial strategy for modern agriculture......»»
Forest monitoring reveals self-cleansing effect of radiocesium in ecosystem after Fukushima Daiichi plant accident
A forest monitoring survey conducted more than 13 years after the Fukushima Daiichi Nuclear Power Plant accident has revealed that the natural downward migration of radiocesium in soil exhibits a decontamination effect that reduces the air dose rate.....»»
Smart soil can water and feed itself
A newly engineered type of soil can capture water out of thin air to keep plants hydrated and manage controlled release of fertilizer for a constant supply of nutrients......»»
Study identifies rhizobacteria to combat Striga and boost sorghum yields in Ethiopia
A research team has identified potential Striga-suppressing rhizobacteria associated with sorghum, which have been shown to significantly reduce Striga seed germination rates. This study highlights the value of soil-borne bacteria as bioherbicides to.....»»
Ground surface conditions found to impact speed and distance of leaking natural gas
When natural gas leaks from a subsurface pipeline, a ground cover of water/snow saturation, asphalt paving or a combination of these can cause the gas to migrate away from the leak site up to three to four times farther than through dry soil, a new s.....»»
Irish peat soils are far more vast than previously known, suggests study
New figures suggest peat soils cover 13% more area than previous peat soil maps, which are useful in land use planning—with peat soils critical in absorbing greenhouse gases (GHG) and helping to meet some of Ireland's most pressing environmental ch.....»»
Kenyan crop contamination outbreak inspires grad student to improve rice storage
While half the global population relies on rice as a staple, about 15% of rice produced each year is contaminated by potentially fatal aflatoxins. Seeing this threaten lives in her home country of Kenya prompted a graduate research assistant to focus.....»»
