All Things Considered on KCCU-HD2

A presidential inauguration is an event defined by huge, sweeping optics: the National Mall full of cheering Americans; a grandiose platform in front of the Capitol building; the parade down Pennsylvania Avenue. And the centerpiece: a speech.

On Monday, President Obama will give his second inaugural address — and he faces a challenge in crafting a speech for this moment.

Modern scientists trying to understand climate change are engaged in an unlikely collaboration — with two beloved but long-dead nature writers: Henry David Thoreau and Aldo Leopold.

The authors of Walden and A Sand County Almanac and last spring's bizarrely warm weather have helped today's scientists understand that the first flowers of spring can continue to bloom earlier, as temperatures rise to unprecedented levels.

The construction industry in the U.S. is staging a comeback. In one indicator, the Commerce Department announced Thursday that new homebuilding has reached its highest level in 4 1/2 years.

While that's a promising sign for the industry, more than 2 million construction jobs have been lost in the sector since employment hit its peak. While some might expect that means plenty of people are ready to fill the new jobs, many markets around the country are actually experiencing a shortage of construction workers.

Getting the results of a genetic test can be a bit like opening Pandora's box. You might learn something useful or interesting, or you might learn that you're likely to develop an incurable disease later on in life.

The federal government hit its debt limit at the end of last year. Since then, the Treasury Department has been taking what it calls "extraordinary measures" to keep the government funded and avoid defaulting on U.S. obligations.

House Republicans are wrestling with the best strategy at a retreat Thursday and Friday in Virginia. And some have been denying that there is a risk of default if the debt ceiling isn't raised.
