You are 200 miles directly above the Martian surface — looking down. This image was taken by the Mars Reconnaissance Orbiter on Jan. 27, 2010. (The color was added later.) What do we see? Well, sand, mostly. As you scroll down, there's a ridge crossing through the image, then a plain, then dunes, but keep looking. You will notice, when you get to the dunes, there are little black flecks dotting the ridges, mostly on the sunny side, like sunbathing spiders sitting in rows. Can you see them?

A sunny day at the beach has plusses and minuses for your health.
A little bit of sun can help your body produce vitamin D, but the sun's ultraviolet radiation raises your risk for skin cancer. And, it turns out, UV radiation poses another threat — it physically weakens your skin.
It's rare that a batter receives a standing ovation for a three-pitch strikeout. But that's exactly what happened last night in Miami.
Adam Greenberg came to the plate in a big-league uniform seven years after his only major-league at bat. As Mark told us last week, Greenberg was a Chicago Cub in 2005 making his major league debut against the Marlins.

An effort to share counter-terrorism intelligence across federal and local law enforcement has turned out to be a useless and expensive exercise that also put Americans' civil liberties at risk, a newly-released Senate subcommittee report (pdf) finds.
The scathing nature of the report is perhaps best summed up by the testimony of Harold "Skip" Vandover, who headed the reporting branch of the Department of Homeland Security.

Generation Y is asking why.
Why is it so hard to find a job? Why is health care so expensive? Smart questions from a smart generation. Their inquiries — and the presidential candidate they think can provide the best answers — could be a decisive factor in the 2012 election. If not the Tipping Point, as least a Tilting Point.
For many millennials, economic prospects are murky.

In their first debate Wednesday night, the two presidential candidates will explain their plans for fixing the U.S. economy.
The problems are complicated and long-standing, so the solutions may not be easy to spell out in the two minutes allowed for each answer under the debate rules.
But President Obama, the Democratic incumbent, and former Gov. Mitt Romney, his Republican challenger, will try, and about 60 million people are expected to tune in. This first debate will focus on domestic issues, with the economy topping the list of homefront problems.
