At about 5:30 p.m. on Monday, two washing machine-sized space probes crashed into the surface of the moon. It was all by design and marked the end of NASA's GRAIL mission.

Last week I shared an interview with Stephan Lewandowsky, a cognitive psychologist and Winthrop Professor in the Department of Psychology at the University of Western Australia. Lewandowsky's recent research investigates why people do or don't accept the lessons of contemporary climate science, and in my post we discussed the provocative new finding that rejecting anthropogenic climate change is associated with conspiratorial thinking.

What do Jesuit priests, gin and tonics, and ancient Chinese scrolls have in common? They all show up in our animated history of malaria.

After the tragedy in Newtown, Connecticut on Friday, many parents dropping their kids off at school this morning are facing a lot of anxiety. Today in Your Health, we asked NPR's science correspondent Shankar Vedantam to come by to talk about how tragedies shape our perceptions of risk.

SHANKAR VEDANTAM, BYLINE: Good morning, David.
GREENE: So tell us what we know from school shootings of the past. I mean, what sort of impact will this tragedy have on parents and how they think?
The Environmental Protection Agency is tightening the standard for how much soot in the air is safe to breathe. Fine particles come from the combustion of fossil fuels by cars and industrial facilities. They're linked to all kinds of health problems, including heart attacks and lung ailments like asthma. States will be required to clean up their air to the level specified by the new standard.
