In an analysis of how regulators review pesticides for their potential to cause cancer, researchers at Silent Spring Institute identified more than two dozen registered pesticides that were linked with mammary gland tumors in animal studies. The new findings raise concerns about how the US Environmental Protection Agency (EPA) approves pesticides for use and the role of certain pesticides in the development of breast cancer.
As humans continue to send large quantities of carbon into the atmosphere, much of that carbon is absorbed by the ocean, and UConn researchers have found high CO2 concentrations in water can make fish grow smaller.
Angel sharks are sharks, but with their peculiarly flat body they rather resemble rays. An international research team led by Faviel A. López-Romero and Jürgen Kriwet of the Institute of Palaeontology has now investigated the origin of this body shape. The results illustrate how these sharks evolved into highly specialised, exclusively bottom-dwelling ambush predators and thus also contribute to a better understanding of their threat from environmental changes. The study is published in the journal Scientific Reports.
Rice is the most widely consumed staple food source for a large part of the world's population. It has now been confirmed that rice can contribute to prolonged low-level arsenic exposure leading to thousands of avoidable premature deaths per year.
Researchers have demonstrated the use of tinted, semi-transparent solar panels to generate electricity and produce nutritionally-superior crops simultaneously, bringing the prospect of higher incomes for farmers and maximising use of agricultural land.
Forty years after Dan Luoma found an unsual truffle collection, scientists confirmed it is a new species and named it after Luoma.
Researchers examined the outcome of an entangled bottlenose dolphin calf with monofilament fishing line wrapped tightly around its upper jaw. It was successfully disentangled and immediately released it back into its natural habitat. Surviving only two years, results showed long-term severe damage due to this entanglement including emaciation. There are about 1,000 bottlenose dolphins that live in the Indian River Lagoon, which also is a very popular location for recreational fishing.
Clean-up devices that collect waste from the ocean surface won't solve the plastic pollution problem, a new study shows.
Finding out if the food and water we consume are safe from toxic and carcinogenic metals can now be much faster and simpler. Researchers at the University Johannesburg developed an efficient and more sensitive method to test for dangerous levels of heavy metals, like arsenic, cadmium and chromium in vegetables and water. The method can be used to test other foods also. A clay-based adsorbent makes testing for several metals at the same time possible.
Like humans, cattle are social creatures with complex relationships that change as group dynamics evolve. New research into social grooming interactions between a small herd of dairy cows illustrated patterns of behavior that could be used to better align future farm management practices with the social needs of bovines. Previous research has demonstrated that happier cows are healthier and more productive.
