Rice crops that can save farmers money and cut pollution
July 29, 2016 03:31 PM - University of Toronto via ScienceDaily

A new U of T Scarborough study has identified "superstar" varieties of rice that can reduce fertilizer loss and cut down on environmental pollution in the process.

The study, authored by U of T Scarborough Professor Herbert Kronzucker in collaboration with a team at the Chinese Academy of Sciences, looked at 19 varieties of rice to see which ones were more efficient at using nitrogen.

"We have this bucolic idea of agriculture -- animals grazing or vast fields of majestic crops -- but the global reality is it's one of the biggest drivers of environmental pollution and climate change," says Kronzucker.

Scientists unlock 'green' energy from garden grass
July 21, 2016 11:52 AM - Cardiff University via EurekAlert!

Garden grass could become a source of cheap and clean renewable energy, scientists have claimed.

A team of UK researchers, including experts from Cardiff University's Cardiff Catalysis Institute, have shown that significant amounts of hydrogen can be unlocked from fescue grass with the help of sunlight and a cheap catalyst.

It is the first time that this method has been demonstrated and could potentially lead to a sustainable way of producing hydrogen, which has enormous potential in the renewable energy industry due to its high energy content and the fact that it does not release toxic or greenhouse gases when it is burnt.

Co-author of the study Professor Michael Bowker, from the Cardiff Catalysis Institute, said: "This really is a green source of energy.

Is your makeup killing sharks?

Natalia Lima, Care2

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.”
