Solar farms could make fertile habitats for bees and butterflies

The buzz about the puzzling mass demise of honey bees, monarch butterflies and other crucial pollinators has prompted plenty of personal protection pledges. Now, a movement is afoot to plant these “gardens” at a much larger scale.

The campaign, advocated by Minnesota-based non-profit Fresh Energy, encourages developers of utility-scale solar projects to plant their land with wildflowers, native grasses and other beneficial vegetation rather than gravel or dirt.

Its pitch: Using just one 2,500-acre solar field for this purpose is like planning 750,000 12-foot by 12-foot backyard pollinator gardens — such as the ones advocated by the Xerces Society.

McConnell: Chemical reform could get a vote in the fall

Read the full story in The Hill.

Senate Majority Leader Mitch McConnell (R-Ky.) said Thursday that an overhaul of federal chemical safety laws could come up for a vote when lawmakers return from their summer recess.

A Senate panel passed a bipartisan update of the Toxic Substances Control Act (TSCA) in April, and McConnell said in June that the bill could hit the floor this summer. But lawmakers never considered it before they left town on Wednesday for a five-week recess.

Bio-inspired robots: A force for good or evil?

Whether for good or ill, robotics has been a prime application venue for bio-inspired design. More organic devices are being developed at an increasing rate because of progress in our ability to process information, make things smaller and use new materials with novel properties.

This pattern undoubtedly will continue, and it is part of a larger technological trend of integrating machine and human interfaces. Our machines will look more and more lifelike — and, perhaps, we will look more and more like machines (witness Google Glass).

Snakeskin: A design breakthrough for robots and race cars?

Even though a snake’s skin is dry as a bone, we often think of it as wet and slick. There’s a good reason for that — the animals have evolved a coating of scales that helps them slide seemingly without effort across any surface.

Nature’s design is actually more complex than just making a supersmooth skin, though: Each scale overlaps the one behind it to diminish friction in the forward direction while creating enough on the rear of the scale to let the snake propel forward. Each scale is also built to maximize resistance against wear.

Expert friction control and durability make snake and lizard skin very interesting to engineers who want to build those characteristics into machines.

Eventually, replica reptile materials could find a use in high-end automotive engineering, such as Formula One racecars, or in the coming generation of search-and-rescue and exploration robots modeled off snakes.

Lost jobs and the collateral damage of climate change

The following is an excerpt from the book “Decent Work, Green Jobs and the Sustainable Economy.”

Environmental challenges and social challenges are inextricably linked. Economic growth, job creation and incomes depend on — and can degrade — natural resources and systems. However, they can also restore and enhance environmental sustainability.

Given the scale and the urgency of these challenges, it is clear that the world will have neither the resources nor the time to tackle them separately or consecutively. They need to be addressed together, in a comprehensive and complementary manner.

The questions are, then, whether and how an environmentally sustainable economy can offer opportunities to create decent work and improve social inclusion.

Green Surfactants Close to Surface

From cosmetics and pharmaceuticals to agricultural products and paint, surfactants are ubiquitous in consumer and industrial areas. The compounds make up a multi-billion-dollar market, according to the NSF.

Taking cues from surfactants made by common bacteria, the Univ. of Arizona research team is exploring new biosurfactants based on sugars generally referred to as glycolipids. The sugar structure ensure the surfactants are biodegradable.

Detroit wildlife refuge could be model for urban conservation

When you think of wildlife refuges, Detroit probably isn’t the first place that pops to mind. But conservation scientists are paying increasing attention to the potential of urban spaces. Current State’s April Van Buren talks with John H. Hartig, who manages the Detroit River International Wildlife Refuge, about his new book “Bringing Conservation to Cities.”
