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.....»»
Compost produced from organic solid waste could replace 21% of industrial fertilizers in urban agriculture
The organic solid waste that citizens deposit in brown recycling bins could currently produce the amount of compost needed to satisfy 8% of the nutrients demanded by urban and peri-urban agriculture, reducing environmental impacts such as soil eutrop.....»»
iPhone roadmap is ‘most ambitious in the product’s history,’ per John Ternus
Innovation on the iPhone looks different than it used to. The product line is coming up on two decades of change, so understandably updates these days are more evolutionary than revolutionary. However, we could be on the cusp of a major wave of iPhon.....»»
People around the world are using courts to question whether climate policies are fair
Coal workers suing their government over job losses. Indigenous people using the courts to block wind farms or anti-deforestation policies that violate their cultural rights. What these cases have in common is they challenge the fairness of climate p.....»»
Biodegradable microplastics study helps quantify their climate change and ecotoxicity impacts
Over 20 million tons of plastic are estimated to end up in the environment every year, with much of it breaking down into microplastics that are harmful to the health of humans and wildlife. Biodegradable and bio-based plastics made from organic mate.....»»

May 2024 super geomagnetic storm challenges current space weather prediction models
During May 2024, a series of eruption events on the sun saw the largest geomagnetic storm hit Earth in two decades. The largest since the solar storms of Halloween 2003, it occurred from May 10 to May 13, producing aurorae as far south as the Canary.....»»
Education and gender equality: Focus on girls isn"t fair and isn"t enough, say researchers
For the past two decades, investing in girls' schooling has been hailed as a cornerstone of promoting gender equality in sub-Saharan Africa. Between 2016 and 2018, the World Bank Group invested US$3.2 billion in education projects benefiting adolesce.....»»
Invasive flathead catfish impacting Susquehanna"s food chain, researchers find
Flathead catfish—native to the Mississippi River basin—were first detected in the Susquehanna River in Pennsylvania in 2002, according to the U.S. Geological Survey. In the two decades since then, the invasive species has spread throughout the ri.....»»
Leveraging skyscraper architecture: New design enhances porosity and structural stability for metal-organic frameworks
The Burj Khalifa, the tallest building in the world, employs advanced construction techniques designed to withstand wind, seismic activity, and its own massive weight. Among these techniques is the "Meta Column System," which plays a pivotal role by.....»»
Bumblebee queens choose to hibernate in pesticide-contaminated soil, scientists discover
An alarming discovery from University of Guelph researchers raises concerns for bumblebee health, survival and reproduction. U of G environmental sciences researchers Drs. Nigel Raine and Sabrina Rondeau have found that bumblebee queens are more like.....»»
A new generation of telescopes will probe the "unknown unknowns" that could transform our knowledge of the universe
In recent decades, we've learned huge amounts about the universe and its history. The rapidly developing technology of telescopes—both on Earth and in space—has been a key part of this process, and those that are due to start operating over the n.....»»
Abiotic organic synthesis research proposes new mechanism for organic condensation
A Chinese research team has reported the discovery of abiotic organic compounds in the oceanic crust of the Southwest Indian Ridge and proposed a molecular mechanism for organic condensation......»»
Aquaculture could harm animal welfare or protect it, depending on what species the farms raise
The global aquaculture industry has tripled in size since the year 2000, with producers raising a mind-boggling diversity of species, from seaweeds and clams to carp, salmon and cuttlefish. Many of these creatures are undomesticated and lead complex.....»»
