How will we feed our growing population in the face of an increasingly extreme climate? Many experts suggest the answer lies in breeding novel crop varieties that can withstand the increases in drought, heat, and extreme rainfall events predicted in the not-too-distant future. But breeding is only part of the equation, according to new research from the University of Illinois and several collaborating institutions across the Midwestern U.S.

"It might not be necessary to put all the stress of climate adaptation and mitigation on new varieties. Instead, if we can manage agroecosystems more appropriately, we can buffer some of the effects of climate instability," says U of I and USDA Agricultural Research Service ecologist Adam Davis.

When you go out for sushi or visit a seafood restaurant, how sure can you be that you’re really getting what you’ve ordered? Last week, Oceana released some shocking findings: Around the world, an average of one in five samples of seafood is mislabeled.

The report examined 25,000 samples worldwide and reviewed more than 200 published studies from 55 different countries. Every continent was represented apart from Antarctica. The mislabeling was present in every part of the seafood supply chain, including retail, wholesale, distribution, import/export, packaging, processing, and landing.

That’s bad news for many reasons – mislabeling makes dining dangerous for consumers (not all of these species are considered suitable for human consumption), and difficult for people who are trying to avoid mercury exposure or who simply want to dine more sustainably. In most cases, cheap fish were being passed off as more expensive varieties.

Marine ecosystems are responsible for about half of global annual primary production and more than one billion people rely on fish as their primary protein source. Latest studies show that enormous warm water bubbles in the ocean are having a noticeable impact on ecosystems. How should we interpret these changes?

This is an issue of global concern. Climate change, urbanization, and resource depletion (more mouths to feed, burn wood in stoves for, graze more cattle for) is still happening at a fast an alarming clip, influencing our planet’s ability to store CO2 emissions, and protect diversity. 

The U.S. National Flood Insurance Program, which holds policies for more than 5 million homes, is $23 billion in debt after a string of natural disasters this century. As climate change further strains the program, analysts say it is time to shift its focus from rebuilding to mitigating risk.

More than 2,100 properties across the U.S. enrolled in the National Flood Insurance Program have flooded and been rebuilt more than 10 times since 1978, according to a new analysis of insurance data by the Natural Resources Defense Council (NRDC). One home in Batchelor, Louisiana has flooded 40 times over the past four decades, receiving $428,379 in insurance payments. More than 30,000 properties in the program, run by the Federal Emergency Management Agency, have flooded multiple times over the years. Those homes, known as “severe repetitive loss properties,” make up just 0.6 percent of federal flood insurance policies. But they account for 10.6 percent of the program’s claims — totaling $5.5 billion in payments.

The new data illustrates the serious problems facing the nation’s flood insurance program. The National Flood Insurance Program (NFIP), which currently provides policies for more than 5 million American homes, is $23 billion in debt following a string of major natural disasters over the last decades, including as Hurricanes Katrina and Sandy.

Mozuku is a unique Okinawan seaweed. Scientifically known as Cladosiphon okamuranus, this alga is popular in Japanese cuisine, and it has been farmed for more than 35 years. The cultivation of this seaweed is a key element in the economy of Okinawa: in 2006, the Japanese Cabinet Office estimated a 20,000 ton production, with an economic value of billions of Yen. 99% of this seaweed is produced in Okinawa, almost entirely farmed by humans. When in 2015 the production dropped for causes related with the higher temperature of the ocean, political institutions and research centres started to coordinate in order to develop a strategy to preserve this Okinawan treasure.

Hundreds of millions of birds are killed in collisions with windows each year in the U.S. alone, and although high-rise buildings tend to be the biggest individual culprits, the vast number of suburban homes across the continent means that even a few deaths per house add up fast. A new study in The Condor: Ornithological Applications examines the factors that affect window collision rates at homes and shows that yards that are more attractive to birds are also the sites of more collisions.

Working with Alberta homeowners who collectively contributed more than 34,000 days' worth of collision data, Justine Kummer of the University of Alberta and her colleagues found that the presence of a bird feeder, whether a house was in an urban or rural area, and the height of the vegetation in the yard were the most important predictors of collisions. Of Alberta's 421 bird species, 53 were represented in the data, mostly common urban species.

Most animal lovers wouldn’t dream of harming an animal for fashion. Fur? No, thank you. Leather? I don’t think so. Yet they might be unknowingly killing sharks — and highly endangered kinds on top of that — for their beauty routine.

Unbeknownst to most, one little ingredient in products like sunscreens, moisturizing lotions, lip balms, lipsticks and face creams is responsible for the death of over three million sharks annually.

Killer ingredient

“Squalene is a naturally occurring compound found in large quantities in the liver of sharks,” explains the shark protection group Shark Trust. “A sharks’ large oily liver helps to control its position in the water column, however many cosmetics companies use the oil (and an associated compound called squalane) as a base for their moisturizing and skin care creams, lipstick and gloss, as it is non-greasy and softens skin.”

Out of the 125,000 K-12 schools in the United States, over 3,700 are running on solar power. Three-thousands of these schools installed their solar power systems within the past six years, as solar technology continues to become less expensive and more sophisticated.

This trend in powering our schools reflects the growing recognition by district and state officials that photovoltaic electrical systems offer significant financial and environmental benefits. Here are four key reasons why more schools are making this transition.

Dining in dimly lit restaurants has been linked to eating slowly and ultimately eating less than in brighter restaurants, but does lighting also impact how healthfully we order?

New research findings forthcoming in the Journal of Marketing Research illustrate that those dining in well-lit rooms are about 16-24% more likely to order healthy foods than those in dimly lit rooms. Furthermore, the researchers found evidence that this effect is due mainly to the level of diners’ alertness. “We feel more alert in brighter rooms and therefore tend to make more healthful, forward-thinking decisions,” explains lead author Dipayan Biswas, PhD, University of South Florida.
