As more urban folk strive to produce their own food, gardens both large and small are popping up everywhere. And while it's not unheard of for city dwellers to keep bees and even chickens, only a brave few have been willing to try their hand at goats.

Like hedge fund manager Mark Spitznagel, who recently tried to revitalize Detroit's Brightmoor neighborhood with a herd of 18 baby goats.

13.7: Cosmos And Culture

Science Defines The Shores Of Our Ignorance

In the quest to understand our world and the universe in which it sits, Marcelo Gleiser advises: "Not all questions have answers. To hope that science will answer all questions is to want to shrink the human spirit, clip its wings, rob it from its multifaceted existence."
Goddard/Arizona State University NASA

The very first time I met Marcelo Gleiser he wanted us to start some trouble. Already established as a leading theoretical physicist, Marcelo wanted us to form a group blog to more fully explore science in its full human context (that blog, of course, became this blog: 13.7 Cosmos And Culture). Both of us retained the passion and excitement for science that had started us on the path to research.

U.S. Offshore Wind Energy Area Would Nearly Double Under New Plan

Originally published on Wed June 18, 2014 11:55 am

The Department of the Interior is proposing a large expansion of U.S. efforts to make energy from offshore winds, with a plan centered off the Massachusetts coast. Here, a 2010 photo shows a sunrise over Nantucket Sound.

A large swath of the Atlantic Ocean could soon be used to generate electricity, as a U.S. agency proposes opening more than 1,000 square miles of ocean to wind energy projects. The area is off the coast of Massachusetts, which has been working on the proposal with federal officials.

Is Collecting Animals For Science A Noble Mission Or A Threat?

Originally published on Wed June 18, 2014 8:29 am

DNA from these crab plovers, collected in Djibouti, Africa, should help scientists figure out how the unusual species fits into the family tree, says the Smithsonian's Helen James.

Behind the scenes at the Smithsonian's National Museum of Natural History, there's a vast, warehouse-like room that's filled with metal cabinets painted a drab institutional green. Inside the cabinets are more than a half-million birds — and these birds are not drab. Their colorful feathers make them seem to almost glow.

Plastics Don't Disappear, But They Do End Up In Seabirds' Bellies

The vast majority of debris in the ocean — about 75 percent of it — is made of plastic. It can consist of anything from plastic bottles to packaging materials, but whatever form it takes, it doesn't go away easily.

While plastic may break down into smaller and smaller pieces, some as small as grains of sand, these pieces are never truly biodegradable. The plastic bits, some small enough that they're called microplastics, threaten marine life like fish and birds, explains Richard Thompson, a professor of marine biology at Plymouth University in the U.K.

The Hubble Space Telescope is being pressed into service to search for a post-Pluto "icy body" as a last stop for NASA's New Horizons probe.

The Baltimore-based committee that metes out observing time for the HST announced today that it is allotting time to look for a suitable Kuiper Belt object for New Horizons to flyby after it passes close to Pluto in July 2015.

'Pink Slime' Is Making A Comeback. Do You Have A Beef With That?

A much-maligned beef product that was once frequently added to hamburger is making a comeback. Two years ago, beef processors cut back sharply on producing what they call "lean, finely textured beef" after the nasty nickname for it, "pink slime," caught on in the media. Now, higher beef prices are leading to increased demand for the product.

To prepare, grocery stores and beef processors are getting ready for a new round of questions from consumers.

Your Brain's Got Rhythm, And Syncs When You Think

Even if you can't keep a beat, your brain can. "The brain absolutely has rhythm," says Nathan Urban, a neuroscientist at Carnegie Mellon University in Pittsburgh.

When you concentrate, Urban says, your brain produces rapid, rhythmic electrical impulses called gamma waves. When you relax, it generates much slower alpha waves.

From red to white to orange to blue, fish flesh can land almost anywhere on the color spectrum.

What's behind this huge variation? A lot of things — from genetics to bile pigments. And parsing the rainbow can tell us something about where a fish came from, its swimming routine and what it ate.

Red yellowfin tuna: A classic of the sashimi counter, the yellowfin tuna is also the Michael Phelps of the fish world. And its athletic prowess has a lot to do with its ruby red flesh.

Finally! A Decent Espresso On The International Space Station

Italian astronaut Luca Parmitano, during his stay on the International Space Station last year, said the one thing he missed was a real cup of espresso.

Engineers on the ground in Italy were way ahead of him.

They had already been hard at work solving the problems of zero-gravity espresso, and now they're ready to launch ISSpresso, "the first capsule-based espresso system able to work in the extreme conditions of space."
