All Things Considered

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.

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 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.

The Aurora, Colo., theater where 12 people were killed in a mass shooting last summer reopens Thursday, with a private event for victims' families and first responders.

But some families are giving the event a pass, arguing that the decision to reopen is insensitive. Jessica Watts lives just a few miles from the theater where her cousin, Jonathan Blunk, and 11 others were killed and dozens more wounded.

People who volunteer for medical research usually expect to remain anonymous. That includes people who donate their DNA for use in genetic studies.

But now researchers have shown that in some cases, they can trace research subjects' DNA back to them with ease. And they say the risk of being identified from genetic information will only increase.

Childhood vaccines for diseases like measles, polio and whooping cough have repeatedly been proved safe and effective. Even so, some parents still worry that the schedule of vaccinations — 24 immunizations by the age of 2 — can be dangerous. That worry is likely misplaced, according to a yearlong review of all available scientific data.
