Johns Hopkins engineers are testing out what they call "untethered microgrippers" as a better way to investigate hard-to-reach places.

President Obama has been hosting a series of visitors from the Middle East, and all of them have been urging the U.S. to get more involved in Syria.

Liyan Chen, a grad student in New York, was chatting online recently with her cousin in China.
"He said, 'I want Abbott milk powder,' " Chen told me. " 'I want you to buy it and ship it back.' "
Her cousin wanted her to buy three boxes of Abbott baby formula, sold under the brand name Similac, and ship it to him in China. She did some research and found out the shipping alone could cost $80. "They're not from a very well-off family, and that really surprised me," she said — especially because they can buy Abbott baby formula in stores in China.

The U.S. has remained at arm's length during two years of bloodletting in Syria that has claimed some 70,000 lives. But when the White House said Thursday it believed Syria has used chemical weapons, even in small quantities, it immediately set off a renewed debate on whether the U.S. might pursue a more aggressive policy.
Here are some of the key issues now under discussion:

Now we turn to Detroit, where police have been reportedly using a pretty controversial method to deal with vagrancy. Allegedly, police are taking homeless people off city streets - particularly in high tourist areas - then driving them outside of the city limits and leaving them there.
