Horse Owners Can Manage Flies with Wasps

Horses need help when it comes to insect pests like flies. But, unfortunately, horse owners are in the dark about how best to manage flies because research just hasn't been done, according to a new overview of equine fly management in the latest issue of the Journal of Integrated Pest Management, an open-access journal that is written for farmers, ranchers, and extension professionals.

Pesticide use leads to endocrine disrupters in French lettuce

An investigation has found that the majority of French lettuce contains traces of hormone disrupting chemicals, some of which are banned. Journal de l Environnement reports. The French NGO Générations Futures released the results of an inquiry into chemical contamination in food products on Tuesday (22 September). After examining the contaminants in strawberries in July 2013, the NGO published a report this week entitled EXPPERT 5, examining lettuce, the fourth most popular vegetable in France.The findings were less than impressive: of the 31 products bought in supermarkets in the French departments of the Oise and the Somme, grown on conventional farms, over 77% contained traces of at least two pesticides, and only 19% were pesticide-free.

How does Aspirin work its miracles?

A recent study led by researchers at the Cornell University-affiliated Boyce Thompson Institute (BTI) in collaboration with colleagues at Rutgers and Italy’s San Raffaele University and Research Institute, shows that aspirin’s main breakdown product, salicylic acid, blocks the protein, HMGB1, which could explain many of the drug’s therapeutic properties.The findings appear Sept. 23, 2015, in the journal Molecular Medicine.“We’ve identified what we believe is a key target of aspirin’s active form in the body, salicylic acid, which is responsible for some of the many therapeutic effects that aspirin has,” said senior author Daniel Klessig, a professor at BTI and Cornell University. “The protein, HMGB1, is associated with many prevalent, devastating diseases, including rheumatoid arthritis, heart disease, sepsis and inflammation-associated cancers, such as colorectal cancer and mesothelioma,” he said.

Nearly half of US seafood supply is wasted

As much as 47 percent of the edible U.S. seafood supply is lost each year, mainly from consumer waste, new research from the Johns Hopkins Center for a Livable Future (CLF) suggests. The findings, published in the November issue of Global Environmental Change, come as food waste in general has been in the spotlight and concerns have been raised about the sustainability of the world’s seafood resources.

Emissions from Melting Permafrost Could Cost Trillions

While rain forests have long scored attention for their role in trapping carbon, discussions concerning the Arctic have centered on whether or not, or how much, we are going to allow companies to drill for oil far up north. Now, scientists are suggesting the Arctic should have renewed focus for another reason: Climate change, accelerated by the melting of permafrost and resulting greenhouse gas emissions, could cost the global economy, in the long run, as much as $43 trillion.

Just how much waste are Americans creating?

A new Yale-led study reveals that we’re disposing of more than twice as much solid waste as we thought we were here in the good ol’ U.S. of A.Published on Sept. 21 in the Nature Climate Change journal and co-authored by Yale professor Julie Zimmerman and University of Florida professor Timothy G. Townsend, this study found that based on landfill measurements instead of government estimates, analysis of figures revealed that America tosses five pounds of trash per person per day.Let that soak in for a moment. Five pounds of garbage. Per day. Per person. But it gets better, and by better, I mean worse.

'Wisdom index' indicates we are not prepared for tsunamis

The world may not be well prepared for the next significant tsunami, reports Northwestern University tsunami expert Emile A. Okal in a new study that includes a “wisdom index” for 17 tsunamis since 2004.

Rising sea levels and stronger storms increase flood danger

New research has found rising sea levels and stronger storms associated with climate change will produce longer-lasting, more intense periods of flooding.

Feds Set Food Waste Reduction Goals

Food waste in the U.S. is a big problem, accounting for about 31 percent of the nation’s food supply, or 133 billion pounds. It makes up 21 percent of U.S. municipal solid waste in landfills, and as a result it accounts for the lion’s share of landfill methane emissions. Methane is a greenhouse gas with a warming potential 21 times that of carbon dioxide — and landfills are the third largest source of methane emissions in the U.S.

Why do Millenials, Gen Y have more trouble keeping excess weight off?

If you are struggling with weight gain, you might be surprised to know that your parents had it easier - they could eat more and exercise less, and still avoid obesity, according to a recent study out of York University's Faculty of Health."Our study results suggest that if you are 25, you'd have to eat even less and exercise more than those older, to prevent gaining weight," says Professor Jennifer Kuk in the School of Kinesiology and Health Science. "However, it also indicates there may be other specific changes contributing to the rise in obesity beyond just diet and exercise."
