Ghosts of past pesticide use can haunt organic farms for decades
Although the use of pesticides in agriculture is increasing, some farms have transitioned to organic practices and avoid applying them. But it's uncertain whether chemicals applied to land decades ago can continue to influence the soil's health after.....»»
Sun shoots out biggest solar flare in almost 2 decades, but Earth should be out of the way this time
The sun produced its biggest flare in nearly two decades Tuesday, just days after severe solar storms pummeled Earth and created dazzling northern lights in unaccustomed places......»»

Scientists develop sticky pesticide to combat pest insects
Researchers from Wageningen University & Research (WUR) and Leiden University have engineered a biological barrier that protects plants from diseases and pests. It concerns a sticky substance that is sprayed on leaves, to which pests stick......»»
Tracing the origins of organic matter in Martian sediments
Although Mars presents a barren, dusty landscape with no signs of life so far, its geological features such as deltas, lakebeds, and river valleys strongly suggest a past where water once flowed abundantly on its surface. To explore this possibility,.....»»
Long-term study finds organic farming leads to adaptations in the genetic material in plants
Plants adapt genetically over time to the special conditions of organic farming. This has been demonstrated in a long-term study conducted at the University of Bonn......»»
Discovery of biomarkers in space—conditions on Saturn"s moon Enceladus simulated in the laboratory
In 2018, very large organic molecules were discovered in ice particles on Saturn's moon Enceladus. It is still unclear whether they indicate the existence of life or were created in some other way. A recent study could help to answer this question. I.....»»
Identity crisis: Climate destroying wonders that gave US parks their names
Glacier National Park's ice fortress is crumbling. The giant trees of Sequoia National Park are ablaze. And even the tenacious cacti of Saguaro National Park are struggling to endure a decades-long drought......»»
Researchers demonstrate low-loss and polarization-independent integrated optical colorless ROADM
The implementation of integrated optical switches shows promise in the size reduction of ROADMs for greater flexibility and compactness, ultimately leading to robust single-chip solutions. Despite decades of research on switches with various structur.....»»
New "forever chemical" cleanup strategy discovered
As the U.S. Environmental Protection Agency cracks down on insidious "forever chemical" pollution in the environment, military and commercial aviation officials are seeking ways to clean up such pollution from decades of use of fire suppressant foams.....»»
