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.....»»
One-pot strategy to simultaneously achieve heterodehydrocoupling of hydrostannane and reduction of quinoline
Heteroatom tin compounds (SSn, OSn, NSn, PSn) composed of heteroatoms S, O, N, P and tin atoms have attracted intense attention due to their wide applications in organic synthesis and pharmaceutical fields. The current methods for synthesis of such c.....»»
Scientists combine a spatially distributed sediment delivery model and biogeochemical model to estimate fluxes by water
Water erosion is the most active process controlling soil formation and evolution, which can affect the redistribution of carbon between terrestrial, aquatic, and atmospheric ecosystems. Erosion-induced organic carbon dynamic process should not be mi.....»»
Family farms are fast disappearing: Research shows how young generations can take them up successfully
While some might think that family-run farms are a thing of the past, they are in fact the dominant business model in Europe. In 2020, they accounted for slightly more than 9 in every 10 of the EU's 9.1 million farms......»»

NASA"s Chandra releases timelapse movies of Crab Nebula and Cassiopeia A
New movies of two of the most famous objects in the sky—the Crab Nebula and Cassiopeia A—are being released from NASA's Chandra X-ray Observatory. Each includes X-ray data collected by Chandra over about two decades. They show dramatic changes in.....»»
A shade closer to more efficient organic photovoltaics
Transparent solar cells will transform the look of infrastructure by enabling many more surfaces to become solar panels. Now, materials called non-fullerene acceptors that can intrinsically generate charges when exposed to sunlight could make semitra.....»»
How studying trends in human lifespans can measure progress in addressing inequality
People are living longer lives compared to previous generations but, over the last few decades, there has been a hidden shift—they are passing away at increasingly similar ages......»»
Sugar gums have a reputation as risky branch-droppers but they"re important to bees, parrots and possums
I had the good fortune to care for the sugar gum at The University of Melbourne's Burnley Gardens in Victoria where I worked for many decades. It was a fine tree—tall and dominating. Less than a year after my retirement, it shed a couple of major l.....»»
A chemical mystery solved—the reaction that explains large carbon sinks
A mystery that has puzzled the scientific community for more than 50 years has finally been solved. A team from Linköping University, Sweden, and Helmholtz Munich have discovered that a certain type of chemical reaction can explain why organic matte.....»»
Apple Silicon might get used for AI chips in server farms
A new rumor claims that Apple will use TSMC's 3nm technology for an AI server processor that it is designing alongside its iPhone and Mac chips.It's already known that TSMC has been developing 3 nanometer processors, and believed that Apple has bough.....»»
Gone in a puff of smoke: 52,000 square kilometers of "long unburnt" Australian habitat has vanished in 40 years
Landscapes that have escaped fire for decades or centuries tend to harbor vital structures for wildlife, such as tree hollows and large logs. But these "long unburnt" habitats can be eliminated by a single blaze......»»
Light-activated materials perform well in treatment of textile effluent
Photoelectrochemical processes have been considered sustainable alternatives for the remediation of water contaminated by domestic or industrial effluents. Simply put, the strategy consists of using solar energy to degrade organic pollutants......»»
Laser-treated cork absorbs oil for carbon-neutral ocean cleanup
Oil spills are deadly disasters for ocean ecosystems. They can have lasting impacts on fish and marine mammals for decades and wreak havoc on coastal forests, coral reefs, and the surrounding land. Chemical dispersants are often used to break down oi.....»»
Record electron temperatures for a small-scale, sheared-flow-stabilized Z-pinch fusion device achieved
In the nine decades since humans first produced fusion reactions, only a few fusion technologies have demonstrated the ability to make a thermal fusion plasma with electron temperatures hotter than 10 million degrees Celsius, roughly the temperature.....»»
New small molecule helps scientists study regeneration
Regenerating damaged tissues or organs has been a dream of scientists for decades. Now, researchers at the FMI and Novartis Biomedical Research have discovered a new molecule that activates a protein involved in regeneration. The tool holds promise f.....»»
First discovery in decades of blue whales near Seychelles
Blue whales are fascinating animals. At 24–30 meters in length (longer than a basketball court) they are the largest creatures on Earth. They are also among the rarest. Estimates suggest that there are only about 5,000 to 15,000 blue whales left in.....»»
The history -- and triumph -- of Arm and Apple Silicon
Decades ago, Apple started down a path that has revolutionized both its own products and the entire technology industry. Here's where Apple Silicon began, and where it's going.Apple's M-series chips rejuvenated the Mac rangeFrom the very beginning of.....»»
Crucial building blocks of life on Earth can more easily form in outer space, says new research
The origin of life on Earth is still enigmatic, but we are slowly unraveling the steps involved and the necessary ingredients. Scientists believe life arose in a primordial soup of organic chemicals and biomolecules on the early Earth, eventually lea.....»»
Scientists assess paths toward maintaining BC caribou until habitat recovers
Thanks to drastic and evidence-based solutions, more southern mountain caribou roam Western Canada today than in previous decades; however, herd numbers are too fragile to sustain themselves without continued intervention......»»
