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 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.
But those measures will run out sometime between the middle of February and early March. Then it's up to Congress to raise the debt limit.
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.
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.
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.
As President Obama unveiled his gun control proposals Wednesday, he highlighted mass shootings at schools in Colorado, Virginia and Connecticut. He also mentioned another group of children, not in school — the ones on the street corners of Chicago.
Chicagoan Annette Holt was at the White House during Obama's address. Her teenage son, Blair, was shot to death five years ago on a Chicago bus as he shielded a fellow student from a spray of bullets.
In Syria, the staple of most meals is a thin, round, flat bread that we would probably call pita.
Back in November, as fierce fighting raged across Syria, people started to run out of this bread. Government forces were attacking bakeries in rebel-held areas and cutting off electricity so mills couldn't grind flour. By late last year, Syrians were desperate.
The Department of the Interior is huge — more than 70,000 employees manage a half-billion acres of public land, mostly in the West. The department does everything from operate national parks to administer Native American social programs and manage wild horses.
