Salt Lake City and County filed one lawsuit.

and an advocacy group plans to launch their own.

Both cite the National Environmental Policy Act.

The law, known as NEPA, requires federal agencies to conduct environmental reviews for projects.

And the plaintiffs say the Department of Homeland Security hasn't done that.

Seema Kakade teaches at the University of Maryland's law school.

She says NEPA is sometimes called the Magna Carta of environmental law.

A similar lawsuit in Maryland put a detention center there on hold.

Now Homeland Security is conducting an environmental review.

Hagfish are long, tubular, deep-sea dwellers.

They kind of look like intestines.

Their bodies are grayish-pink, and they have teeth but no jaw.

They're not cute, but Utah State biology professor Justin Jones says they have something else going for them.

They exude a slime when they're bitten to clog the gills of predators.

And it's useful because of its fibers.

Jones' lab can make those fibers without any hagfish involved.

Now they're studying how to turn them into clothing.
