"Fishing" for toxic contaminants using superparamagnetic nanoparticles
Once a water source is contaminated, it can be costly and difficult to remediate. Natural remedies can take hundreds of years and still may not successfully remove all the dangerous contaminants. When it comes to global public health issues such as t.....»»
Impact of drought on drinking water contamination: Disparities found affecting Latino/a communities
Long-term exposure to contaminants such as arsenic and nitrate in water is linked to an increased risk of various diseases, including cancers, cardiovascular diseases, developmental disorders and birth defects in infants......»»
Community focused approaches to fisheries governance transform local perceptions
A new study from WCS reveals that community capacity-building interventions, even those with only indirect environmental links, significantly improved perceptions of fisheries management and conservation in coastal fishing villages in East Africa. Th.....»»
Fishing disrupts squaretail grouper mating behavior, study finds
Populations of squaretail grouper face an uncertain future as new research shows fishing that targets their spawning sites is causing males to be repeatedly scared away from their territories during their short mating meetups......»»
Big sharks equal big impact, but there"s a big problem: Those most affected by fishing are most needed for ocean health
Shark conservation must go beyond simply protecting shark populations—it must prioritize protecting the ecological roles of sharks, according to new research published in Science......»»
Researchers develop an energy efficient, reusable, and versatile catalytic system using abundant cobalt
Controlling the crystal phase of cobalt nanoparticles leads to exceptional catalytic performance in hydrogenation processes, report scientists from Tokyo Tech......»»
Ammonia-free gallium nitride semiconductor production found to improve crystal quality, reduce environmental impact
Gallium nitride (GaN) semiconductors can now be grown without ammonia, a toxic chemical that needs a sophisticated detoxifying system before it can be released into the atmosphere. The new technique is not only more environmentally friendly but also.....»»
Green synthesis of copper oxide nanoparticles from mangifera indica: A solution for agricultural disease management
A research team has successfully synthesized green copper oxide nanoparticles (CuO.NPs) from Mangifera indica (M. indica) leaf extract. The CuO.NPs showed potent activity against gram-positive and negative bacteria, as well as fungicidal effects on p.....»»
Air pollution makes it harder for bees to smell flowers
Contaminants can alter plant odors and warp insects’ senses, disrupting the process of pollination. Scientists are uncovering various ways that air pollution can interfere with the ability of insects to pollinate plants. (credi.....»»
Exploring cadmium-induced alterations in the expression profile of microRNAs
Cadmium (Cd), a toxic heavy metal, has been identified as a significant environmental pollutant due to its widespread industrial use and persistence in the environment. Chronic exposure to Cd poses a considerable threat to human health, as it accumul.....»»
New nanoparticles boost immune system in mice to fight melanoma and breast cancer
Vanderbilt researchers have developed a set of nanoparticles that stimulate the immune system in mice to fight cancer and may eventually do the same in humans......»»
Seabirds are threatened by trawl fisheries, study finds
Seabirds are among the most threatened creatures globally, often due to incidental mortality (bycatch) in fisheries. Several hundreds of thousands of seabirds are thought to be killed worldwide each year by two of the three main types of fishing gear.....»»
Reducing carbon dioxide to acetate with a polyaniline catalyst coated in cobalt oxide nanoparticles
Acetic acid, also known as acetate, and other products that can be developed from acetic acid are used in a variety of industries, from food production to medicine to agriculture. Currently, acetate production uses a significant amount of energy and.....»»
"Truly frightening": Pesticides increasingly laced with forever chemicals
Toxic "forever chemicals" are increasingly being used in US pesticides, threatening human health as they contaminate waterways and are sprayed on staple foods, a study said Wednesday......»»
Study links nanoparticles to oxidative stress and neuron death
Researchers at the University of Kentucky have a better understanding of the regulation of extracellular vesicles by oxidative stress and how these vesicles spread oxidative stress and may damage neurons. Extracellular vesicles are nanoparticles rele.....»»
Woodchip bioreactor helps reduce pesticide run-off from horticulture greenhouses
Pesticides seeping out of intensive horticulture into waterways have long-concerned NSW north coast communities. Now a new Southern Cross University study provides evidence that bioreactors can significantly limit this toxic run-off......»»
New car smell reaches toxic levels on hot days, researchers find
A study of volatile organic compounds (VOCs) emitted by new cars on hot summer days finds concerning levels of formaldehyde and other aldehydes......»»
Gold co-catalyst improves photocatalytic degradation of micropollutants, finds study
To remove micropollutants such as pesticides and trace chemicals from the environment, you need something equally small and cunning. One potential method is photocatalysis, which uses semiconducting nanomaterials powered by sunlight to adsorb toxic c.....»»
Environmental groups ask feds to take over Georgia"s coal ash program
A handful of environmental groups filed a petition July 18 asking the U.S. Environmental Protection Agency (EPA) to claw back oversight of the disposal of Georgia's toxic coal ash from state regulators, citing concerns over groundwater contamination......»»
Crown-of-thorns starfish larvae feast on toxic cyanobacteria, study finds
Researchers have uncovered an under-the-sea phenomenon where coral-destroying crown-of-thorns starfish larvae have been feasting on blue-green algae bacteria known as "sea sawdust.".....»»
Study shows how organic molecules impact gold nanoparticles" electrochemical properties
A new study shows how organic molecules greatly influence the redox potential of gold nanoparticles, with differences up to 71 mV. Using experiments and computer simulations, the study highlights the important role of capping agents in controlling th.....»»
