The chemical industry produces not just valuable vitamins, pharmaceuticals, flavours and pesticides, but often a large amount of waste, too.This is particularly true of pharmaceutical and fine-chemical production, where the volume of desired product may be just a fraction of the volume of waste and unsaleable by-products of synthesis.Pérez-Ramírez and his group have now collaborated with other European scientists and an industry partner to develop just such a solid catalyst for a major chemical reaction, as the researchers report in the magazine Nature Nanotechnology.Their catalyst is a molecular lattice composed of carbon and nitrogen atoms (graphitic carbon nitride) that features cavities of atomic dimensions into which the researchers placed palladium atoms.Efficient catalyst for a Nobel-prizewinning reactionBy making tiny particles of this palladium-carbon-nitrogen material, the scientists were able to show that it catalyses what is known as the Suzuki reaction very efficiently.
DURHAM, N.C. -- The last 10 years have seen a surge in the use of tiny substances called nanomaterials in agrochemicals like pesticides and fungicides.But when combined with nutrient runoff from fertilized cropland and manure-filled pastures, these "nanopesticides" could also mean more toxic algae outbreaks for nearby streams, lakes and wetlands, a new study finds.The results appear June 25 in the journal Ecological Applications.Too small to see with all but the most powerful microscopes, engineered nanomaterials are substances manufactured to be less than 100 nanometers in diameter, many times smaller than a hair's breadth.Those interactions could intensify harmful algal blooms in wetlands, according to experiments led by Marie Simonin, a postdoctoral associate with biology professor Emily Bernhardt at Duke University.They are also used on farms for slow- or controlled-release plant fertilizers and pesticides and more targeted delivery, and because they are effective at lower doses than conventional products.
So what can we actually do about it day-to-day?The big things that can be done to clean our air, such as a potential petrol and diesel car ban by 2030, are ultimately jobs for the government.Here are a few tips for you to try this Clean Air Day, and for the rest of the year.Buy organic when you canThis is a great thing to do as part of a sustainable lifestyle, but particularly to keep certain pollutants out of the air.Organic products are likely to have been grown and processed with less pesticides, resulting in less chemicals being released into the air.
The project will use a biological method for manufacturing pheromones, which provide a safe and sustainable alternative to harmful pesticides, reducing the environmental impact of agriculture.In project SUSPHIRE, the team of European scientists aim to use synthetic biology to produce insect sex pheromones in plants and fungi, building on the success of the Polytechnic University of Valencia's entry into the 2014 iGEM competition with project "SexyPlant" in which they produced insect sex-pheromones in plants.Improving on the initial proof-of-concept, the new research will identify and validate key biosynthetic enzymes for the bioproduction of the superfamily insect group Coccoidea (scale insects and mealybugs) pheromones.Bioengineering can provide viable alternatives to manufacturing, expanding the use of pheromones that will be much kinder to our environment."Dr Diego Orzaez, who will present the project at ACHEMA, The World Forum and Leading Show for the Process Industries, in Frankfurt, added: "With an ever-growing global human population, increasing agricultural production through prevention of crop losses to pests has the potential for enormous economic and social impact.Further information on pesticide use
Unfortunately, to show our appreciation, humans are killing off bees in staggering numbers—destroying their habitats and poisoning them with pesticides.In a greenhouse at West Virginia University, a machine called the BrambleBee is learning to roll around pollinating blackberry bushes, knocking their flowers around (blackberry flowers self-pollinate, so bees or robots just have to jostle them to spread around the pollen).It's no replacement for bees, but in a world with too many humans and not enough pollinators, robots like this could help feed our kind.First it uses lidar, spraying lasers to build a 3-D map of the greenhouse so it can find its way around.For the moment, it looks for QR codes as a stand-in for flowers, but the researchers are close to getting it to snap photos of actual flowers.Next, once it’s positioned itself in front of a plant, another camera on that arm will make an even higher-resolution 3-D map of the crop.

The many threats facing bumblebees can be tested using a "virtual safe space" created by scientists at the University of Exeter.Bumble-BEEHAVE provides a computer simulation of how colonies will develop and react to multiple factors including pesticides, parasites and habitat loss.The tool lets researchers, farmers, policymakers and other interested parties test different land management techniques to find out what will be most beneficial for bees.Field experiments can be very timely and costly, so results from Bumble-BEEHAVE can help refine and reduce the number of experiments needed."We know that pollinator decline is a really big problem for crops and also for wildflowers," said Dr Grace Twiston-Davies, of the Environment and Sustainability Institute at the University of Exeter's Penryn Campus in Cornwall."It's a free, user-friendly system and we're already starting to work with land managers and wildlife groups on the ground."
To slow the evolutionary progression of weeds and insect pests gaining resistance to herbicides and pesticides, policymakers should provide resources for large-scale, landscape-level studies of a number of promising but untested approaches for slowing pest evolution.Such landscape studies are now more feasible because of new genomic and technological innovations that could be used to compare the efficacy of strategies for preventing weed and insect resistance.That's the takeaway recommendation from a North Carolina State University review paper addressing pesticide resistance published today in the journal Science.Pesticide resistance exacts a tremendous toll on the U.S. agricultural sector, costing some $10 billion yearly.Costs could also increasingly accrue on human lives.Consider glyphosate, the powerhouse weed killer used ubiquitously in the United States to protect major crops like corn and soybeans.

With several types of bees and bumblebees on the endangered-species list, some governments are starting to do their part to protect the lives of these essential pollinators.The European Union voted Friday to ban outdoor use of pesticides that harms bees.The new restrictions go further in protecting bees than those put in place in 2013 that only banned the use of neonicotinoids used on specific crops."The commission had proposed these measures months ago, on the basis of the scientific advice from the European Food Safety Authority," Vytenis Andriukaitis, commissioner for health and food safety, said in a statement on Friday."Bee health remains of paramount importance for me since it concerns biodiversity, food production and the environment."Bayer Crop Science, the company that developed one of the banned neonicotinoids, said it was a "sad day for farmers and a bad deal for Europe."
The European Union is taking drastic steps to help protect the world’s bee population and will ban the most commonly used pesticides by the end of the year.The ban applies to open fields, but not closed greenhouses.The move follows many studies indicating that these pesticides are contributing to a drastic decrease in bee populations, an issue that threatens the world’s crops.The restriction applies to pesticides known as neonicotinoids, which are: clothianidin, imidacloprid, and thiamethoxam.The EU points toward a recent scientific review from the European Food Safety Authority (EFSA), which has found that most neonicotinoids are harmful to bee populations.This isn’t the first time Europe has targeted pesticides as a way to save bees.
Three pesticides have caused colony collapse disorder will be banned in the EU.Europe's bees no longer need to worry about for three pesticides that have been identified as involved in recent years, colony collapse disorder.the EU's member states have at least decided to ban the outdoor use of the three neonikotinoiderna imidacloprid, clothianidin and thiamethoxam, developed by the German Bayer and u.s. Syngenta.the Subjects have since 2013 has already been a ban on the cultivation of, for example, maize, oilseed rape and sunflowers, but is now stopped for all uses, with the exception of the greenhouses."I am pleased that member states now finally dare to take the ban to the full.Our organic system requires that the bees survive and succeed pollinate", comments the Swedish EU-mep Fredrick Federley (C) via text message to TT.
Biologists at the University of California San Diego have developed a method of manipulating the genes of an agricultural pest that has invaded much of the United States and caused millions of dollars in damage to high-value berry and other fruit crops.Research led by Anna Buchman in the lab of Omar Akbari, a new UC San Diego insect genetics professor, describes the world's first "gene drive" system--a mechanism for manipulating genetic inheritance--in Drosophila suzukii, a fruit fly commonly known as the spotted-wing drosophila.As reported April 17 in the Proceedings of the National Academy of Sciences, Buchman and her colleagues developed a gene drive system termed Medea (named after the mythological Greek enchantress who killed her offspring) in which a synthetic "toxin" and a corresponding "antidote" function to dramatically influence inheritance rates with nearly perfect efficiency."We've designed a gene drive system that dramatically biases inheritance in these flies and can spread through their populations," said Buchman.It's a new method for manipulating populations of these invasive pests, which don't belong here in the first place."Native to Japan, the highly invasive fly was first found on the West Coast in 2008 and has now been reported in more than 40 states.
The small acreage she rents from her family’s farm to grow corn, soybeans, and small grains and raise chickens, hogs, and sheep, is surrounded by large swaths of conventional corn and soy.“All winter long, I go to meetings set up for the conventional system of corn and [soy]beans,” Johnson, who runs Joia Food Farm, wrote in an email recently.And this is at one of the top ag universities in the U.S.”In an industry now worth $47 billion, organic certification can earn farmers like Johnson a premium, and the growth in demand has been consistent, year over year.And although Johnson believes deeply that farming in harmony with the natural world—and without synthetic pesticides—is the right thing to do, she is less sure that the economic boost organic offers can make a real difference to turn around some of the most challenging trends in Iowa.Meanwhile, Congressman Peter Welch, a Democrat from Vermont, has been mulling the same set of questions in his state—where rural residents find themselves in a very different universe from their rural and suburban counterparts.
Chemical pesticides play a vital role in modern agriculture by helping to protect crops against a range of pests and diseases.However, while there is no denying how useful they are, they also come with potential negatives.They have created a new eco-friendly RNA-based vaccine, designed to help plants fight back without damage to the surrounding environment.The vaccine works by triggering RNA interference.This describes an automatic defense mechanism found in plants, animals, and other eukaryotic organisms.“To reduce the application of chemical pesticides, our technology proposes the treatment of plants with nature-derived double-stranded dsRNA molecules,” Manfred Heinlein, a cell biology expert who worked on the project, told Digital Trends.
Scientists working in the Antarctic have announced that the very first crop of vegetables has been harvested in a new greenhouse that doesn’t use any earth, daylight, or pesticides.The project is part of research that is designed to help astronauts to cultivate fresh foods on other planets.The greenhouse is at the German Neumeyer-Station III.So far the researchers have picked about eight pounds of salad greens, 18 cucumbers, and 70 radishes that were all grown inside a high-tech greenhouse while outside temperatures are in the -20C range.The researchers hope to be able to harvest 4-5kg of fruit and vegetables weekly from their greenhouse.That would be over eight pounds of fresh edibles per week.
You don’t have to be a pamphlet-distributing, faux leather-shoe wearing militant vegetarian to realize that vegetables are going to be pretty important in space.Whether it’s long periods of time spent on the International Space Station or the eventual dream of colonizing other planets, the ability to grow veg outside of Earth’s atmosphere is going to be crucial for our survival.Or, at least, our ability to enjoy life in the stars without suffering from a massive lack of fiber and assorted nutrients.Fortunately, science is here to help.Scientists in Antarctica this week announced that they have successfully grown the first crop of vegetables without the help of earth, daylight or pesticides.This was achieved using cutting-edge hydroponics techniques — including replacing the soil with nutrient-rich water and using LED lighting to double for sunlight.
Novel technologies are being sought to replace the traditional pesticides used to protect plants, particularly edible plants such as cereals.A new collaborative project between the University of Helsinki and the French National Centre for Scientific Research (CNRS) is shedding light on the efficacy of environmentally friendly RNA-based vaccines that protect plants from diseases and pests.Plant diseases and pests cause considerable crop losses and threaten global food security.The diseases and pests have traditionally been fought with chemical pesticides, which spread throughout our environment and may be hazardous to human health, beneficial organisms and the environment."A new approach to plant protection involves vaccinating plants against pathogens with double-stranded RNA molecules that can be sprayed directly on the leaves," explains Dr Minna Poranen of the Molecular and Integrative Biosciences Research Programme at the University of Helsinki's Faculty of Biological and Environmental Sciences.The vaccine triggers a mechanism known as RNA interference, which is an innate defence mechanism of plants, animals and other eukaryotic organisms against pathogens.
Australian scientists have confirmed the hybridisation of two of the world's major pest species, into a new and improved mega-pest.One of the pests, the cotton bollworm, is widespread in Africa, Asia and Europe and causes damage to over 100 crops, including corn, cotton, tomato and soybean.It is extremely mobile and has developed resistance to all pesticides used against it.The other pest, the corn earworm, is a native of the Americas and has comparatively limited resistance and host range.Australia's Commonwealth Scientific and Industrial Research Organisation (CSIRO) researchers in a paper published in the Proceedings of the National Academy of Sciences of the USA provides clear evidence of the hybridisation of the two moths in Brazil."A hybrid such as this could go completely undetected should it invade another country," Research Director leading CSIRO's Biosecurity Risk Evaluation and Preparedness Program Dr Paul De Barro said.
