Since 2010, the scientific literature has exploded with research examining light’s effects on individual species, from birds to fish to trees to humans. The news, in general, isn’t good. Artificial light changes animal migration and reproduction, tree leaf growth, bird nesting and fledging, pollination, human sleep, and much more. It even affects the spread of diseases. In July, researchers reported that West Nile–virus–infected house sparrows that live in light- polluted conditions are infectious for two days longer than those that live in darkness are, increasing the risk of a West Nile outbreak by 41 percent.

Jeans into insulation, plastic bottles into coats – details like this make people more inclined to use the blue bin.

When you throw something in the recycling bin, do you ever stop to think about what it could become? And when you do, does it make you more inclined to use that recycling bin, instead of lazily tossing an item in the trash? Several consumer psychologists designed a study around these questions, in an effort to determine whether or not explaining to people what their recyclables are transformed into would help boost recycling rates.

The University of Alberta’s vice-president of university relations has resigned over the school’s “beefier barley” billboards, which were slammed as promoting climate change.

“The messaging on the ad called the reputation of the University of Alberta and its extensive research on climate change into question,” vice-president of university relations Jacqui Tam said in an announcement posted Sunday.

“As Vice-President (University Relations), I apologize for this and take responsibility. In the best interests of the institution, I am announcing my departure from the University of Alberta, effective immediately.”

Imagine waking up every morning in a house that is just as alive as you are. With synthetic biology, your future home could be a living, breathing marvel of nature and biotechnology. Yes, it’s a bold ambition. But this kind of visionary thinking could be the key to achieving sustainability for modern cities.

A new analysis of whales suggests that each one is worth about $2 million in carbon sequestration — and the global population is thus worth about $1 trillion.

How do whales sequester carbon? By eating stuff, getting big, then drifting to the bottom of the ocean after they die. This makes them carbon sinks on a scale even bigger than most trees

Many traced the issue to the 1980s when a massive flood left turmeric crops wet and relatively dull in color. Demand for bright yellow curry led turmeric processors to add lead chromate—an industrial yellow pigment commonly used to color toys and furniture—to their product. The practice continued as a cheap, fast way to produce a desirable color.

There’s a new trend in tea — out with the old, flat paper tea bags and in with the pyramid-shaped mesh bags that allow bigger leaves extra breathing room. The bags, which have been around since at least 2006, are sometimes called “silken” sachets. They can be made from hemp, corn-based plastics, nylon or PET (polyethylene terephthalate). But most often it’s one of the latter two: plastics.

But research out this week in Environmental Science & Technology reveals that plastic tea bags are doing a lot more than holding on to your tea. When you steep them in hot water — AKA make tea — they break down just enough to release billions of plastic microparticles right into your beverage.

In September 2018, a project in Myanmar used drones to fire “seed missiles” into remote areas of the country where trees were not growing. Less than a year later, thousands of those seed missiles have sprouted into 20-inch mangrove saplings that could literally be a case study in how technology can be used to innovate our way out of the climate change crisis.
