Reducing pesticide use with nanoparticles
Researchers at the Adolphe Merkle Institute and the Department of Biology at the University of Fribourg have discovered how certain silica nanoparticles could act as a traceless, degradable, and highly efficient treatment against some plant pathogens.....»»
Ecological impact of eucalyptus trees: Balancing benefits and risks
A new study has found that Eucalyptus trees, widely planted in Israel's Western Negev, have a significant allelopathic effect, reducing herbaceous plant biomass and flowering density of red anemones, particularly in unshaded areas......»»
New approach uses "cloaked" proteins to deliver cancer-killing therapeutics into cells
An interdisciplinary collaboration has designed a way to "cloak" proteins so that they can be captured by lipid nanoparticles, which are akin to tiny bubbles of fat. These bubbles are small enough to sneak their hidden cargo into living cells, where.....»»
Producing gold nano-particles (and hydrogen) in water without the need for toxic chemicals
In a surprise discovery, Flinders University nanotechnology researchers have produced a range of different types of gold nanoparticles by adjusting water flow in the novel vortex fluidic device—without the need for toxic chemicals. The article, "Na.....»»
Ambitious targets are needed to end ocean plastic pollution by 2100, analysis finds
A collaboration between researchers at Imperial College London and GNS Science, suggests that reducing plastic pollution by 5% per year would stabilize the level of microplastics—plastics less than 5 mm in length—in the surface oceans......»»
Study unveils strategy for improving mechanical properties of aluminum composites
Particle-reinforced aluminum matrix composites (PRAMCs), in which the aluminum matrix is reinforced with nanoparticles, exhibit great potential for applications in the aerospace and automobile industries. These materials combine the advantages of bot.....»»
Packaged-meat labels that show freshness could replace use-by dates, reducing food waste
Patches that change color as raw meat freshness deteriorates in sealed refrigerated products could soon become a reality on supermarket shelves, making it easier for shoppers to know if it's still good to eat and reducing food waste......»»
Forvia headlamp concept cuts weight, emissions while upholding performance
A new headlamp concept by French supplier Forvia promises 60 percent weight savings over a traditional light while reducing carbon emissions by more than two-thirds over its life......»»
Apple likely to produce quarter of iPhones in India by 2028, not half by 2027 as predicted
Apple plans to boost its iPhone production in India, increasing from below 15% to 25% by 2028. This target underscores Apple’s commitment to building a robust network of local suppliers and reducing its reliance on Chinese suppliers. It’s also a.....»»
Decarbonization dynamics: New analysis unveils shifting trends in the voluntary carbon offset market
As humanity grapples with the fight against climate change, reducing greenhouse gas emissions is urgently necessary. One way to achieve this is through the carbon offset market, where organizations or individuals can buy credits from emissions-reduci.....»»
Early retirement of old vehicles won"t save the planet, says study
Lifespan caps for passenger vehicles have limited effect on reducing greenhouse gas emissions and could drive up costs and material use, finds a new study published in Environmental Research: Infrastructure and Sustainability. The research shows that.....»»
Reducing distrust in social media is not straightforward, computer scientists warn
Are anti-misinformation interventions on social media working as intended? It depends, according to a new study led by William & Mary researchers and published in the Proceedings of the CHI Conference on Human Factors in Computing Systems (CHI '24)......»»
How scientific conference attendees can reduce their carbon footprint
Climate researchers often emphasize the fact that reducing carbon emissions is in everyone's best interest, and should involve all of us. But how good are they at minimizing their own carbon footprint?.....»»
Uneven strain distribution induces detwinning in penta-twinned nanoparticles
Twinned nanoparticles have regions of clear symmetry that share the same crystal lattice, separated by a clear boundary. Changing the twin structure can affect the properties of the nanoparticles, which makes controlling twinning to create tailored n.....»»
How do we reduce pesticide use while empowering farmers? A more nuanced approach could help
Pesticides threaten humans, wildlife and our environment. Food production must change......»»
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......»»
Research explores ways to mitigate the environmental toxicity of ubiquitous silver nanoparticles
Silver has long been used to thwart the spread of illness and in recent years silver nanoparticles have been incorporated into products ranging from sanitizers, odor-resistant clothes and washing machines to makeup, food packaging and sports equipmen.....»»
Reducing prejudice in war zones proves challenging
There are 62.5 million internally displaced persons worldwide, according to 2022 data by the UNHCR, the United Nations Refugee Agency. These individuals were forced to leave their homes but remain in the same country......»»
Researchers can now accurately measure the emergence and damping of a plasmonic field
An international research team led by Universität Hamburg, DESY, and Stanford University has developed a new approach to characterize the electric field of arbitrary plasmonic samples, like, for example, gold nanoparticles. Plasmonic materials are o.....»»
A photocatalyst for sustainable syngas production from greenhouse gases
Researchers have developed a novel photocatalyst, named Rh/InGaN1-xOx, which is a nanoarchitecture consisting of rhodium nanoparticles anchored on oxygen-modified indium gallium nitride nanowires grown on silicon substrates......»»
Computer models show heat waves in north Pacific may be due to China reducing aerosols
A team of oceanographers and planetary scientists at the Ocean University of China, working with a pair of colleagues from the U.S. and one in Germany, has found via computer modeling, that recent heat waves in the north Pacific may be due to a large.....»»
