Researchers show pesticide contamination is more than apple skin deep
Researchers reporting in ACS’ Nano Letters have developed a high-tech imaging method to detect pesticide contamination at low levels, and its application on fruits reveals that current food safety practices may be insufficient.
ALS diagnosis and survival linked to metals in blood, urine
People with higher levels of metals found in their blood and urine may be more likely to be diagnosed with — and die from — amyotrophic lateral sclerosis, or ALS, a University of Michigan-led study suggests.
New solutions to keep drinking water safe as pesticide use skyrockets worldwide
Water scientists from Australia and China have proposed a more effective method of removing organic pesticides from drinking water, reducing the risk of contamination and potential health problems.
Unlocking banana disease resistance: key enzymes identified for phytoalexin synthesis
A breakthrough in banana disease resistance was achieved with the identification of novel O-methyltransferases (OMTs) involved in the biosynthesis of phenylphenalenone phytoalexins. These compounds, found in wild bananas, hold promise for developing disease-resistant commercial cultivars.
Study Finds Pesticide Use Linked to Parkinson’s in Rocky Mountain, Great Plains Region
Pesticides and herbicides used in farming have been linked to Parkinson’s disease in the Rocky Mountain and Great Plains region of the country, according to a preliminary study released today, February 27, 2024, that will be presented at the American Academy of Neurology’s 76th Annual Meeting taking place April 13–18, 2024, in person in Denver and online.
Pesticides to help protect seeds can adversely affect earthworms’ health
Research published in ACS’ Environmental Science & Technology Letters reveals that worms are affected by small amounts of chemicals from pesticide-treated seeds.
Drawing a tube of blood could assess ALS risk from environmental toxin exposure
Investigators have developed a new risk score that assesses a person’s risk for developing ALS, as well as for survival after diagnosis, using a blood sample based on exposure to toxins in the environment, a new study shows.
An Environmental Wake-Up Call for Neurology
The Presidential Symposium at the American Neurological Association’s 2022 Annual Meeting (ANA2022) in Chicago will shine a spotlight on the role of environmental exposures — air pollution, pesticides, microplastics, and more — in diseases like dementias and developmental disorders.
A midge fly can be a source of currently used pesticides for birds, bats
Researchers reporting in ACS’ Environmental Science & Technology have observed that non-biting midge larvae accumulate contemporary pesticides from polluted water and retain the substances into adulthood. As a result, animals that eat the adult flies could consume small amounts of pesticides daily.
Americans should see improved water quality after federal judge strikes down water pollution rule, WVU scientist says
Nicolas Zegre, a hydrology researcher at West Virginia University, is available to discuss the recent ruling tossing Trump-era regulations allowing pollution — including industrial waste, pesticides and other chemicals — to be discharged into small streams and other waterways.
Protecting gardens and crops from insects using the ‘smell of fear’
Herbivorous insects are a threat to gardeners’ hard work, and are increasingly resistant to pesticides. Today, scientists report they have bottled the “smell of fear” from predators to repel destructive insects without the need for harsh substances. They will present their results at ACS Fall 2021.
Two strands are tougher than one
Despite assumptions, dsRNA has traits that make it stand apart from the more common single-stranded RNA. The finding has implications for a range of fields
Pollen-sized technology protects bees from deadly insecticides
A Cornell University-developed technology provides beekeepers, consumers and farmers with an antidote for deadly pesticides, which kill wild bees and cause beekeepers to lose around a third of their hives every year on average.
WHO ‘needs to act’ on suicides caused by pesticides
Scientists are calling for more stringent pesticide bans to lower deaths caused by deliberately ingesting toxic agricultural chemicals, which account for one fifth of global suicides.
Experimental Biology 2021 Press Materials Available Now
Embargoed press materials are now available for the virtual Experimental Biology (EB) 2021 meeting, featuring cutting-edge multidisciplinary research from across the life sciences. EB 2021, to be held April 27–30, is the annual meeting of five scientific societies bringing together thousands of scientists and 25 guest societies in one interdisciplinary community.
Risk factors in India mystery illness make cause difficult to determine
This month, more than 500 people have been hospitalized in southern India with a mysterious illness. Lead and nickel were found in blood samples from those hospitalized and organochlorine, normally found in pesticides, was also found in some water samples.…
Bacteria Can Defuse Dangerous Chemical In Passaic River
Bacteria that can help defuse highly toxic dioxin in sediments in the Passaic River – a Superfund hazardous waste site – could eventually aid cleanup efforts at other dioxin-contaminated sites around the world, according to Rutgers scientists. Their research, published in the journal Environmental Science & Technology, needs further work to realize the full potential of the beneficial bottom-dwelling microbes.
Data omission in key EPA insecticide study shows need for critical review of industry analysis
For nearly 50 years, a statistical omission tantamount to data falsification sat undiscovered in a critical study at the heart of regulating one of the most controversial and widely used pesticides in America — chlorpyrifos.
Poison control: Chasing the antidote
A fast-acting antidote to mitigate the effects of organophosphate poisoning requires a reactivator that can effectively and efficiently cross the blood-brain barrier, bind loosely to the enzyme, chemically snatch the poison and then leave quickly. Oak Ridge National Laboratory is using neutron diffraction data towards improving a novel reactivator design.
Rutgers Expert Can Discuss Earthwise Lawn and Landscape Care, Farming
New Brunswick, N.J. (June 15, 2020) – Rutgers University–New Brunswick Professor William T. Hlubik is available for interviews on environmentally friendly lawn and landscape care, sustainable gardening and agriculture, home and commercial vegetable and small fruit production, and how to…
Lights out? Fireflies face extinction threats of habitat loss, light pollution, pesticides
Habitat loss, pesticide use and, artificial light are the three most serious threats endangering fireflies across the globe, raising the spectre of extinction for certain species whose features render them more vulnerable to specific threats. Impacts range from loss of biodiversity to ecotourism.
Study finds potential link between cardiovascular death and some types of pesticides
A new data analysis from the University of Iowa finds that people who have high levels of exposure to pyrethroid insecticides are three times more likely to die of cardiovascular disease than people with little or no exposure.
