Goldman Sachs on Monday downgraded BlackBerry after a disappointing launch for the company's new smartphone, the Z10.

The Wall Street Journal reports that Goldman slashed its investment rating on the Canada-based company — formerly known as Research in Motion, or RIM — to neutral from buy, citing weak support for the new product.

Tiger Woods is back on top. With his victory at the Arnold Palmer Invitational at Bay Hill, Woods is now ranked the No. 1 player in the world.

As The Washington Post explains, this is the first time Woods is at the top since both his personal life and his professional life crumbled following a 2009 cheating scandal that ended in divorce and a plummet from the top of the golf world.

The Post says:

A nearly 5 mile section of 1604 on the Northwest Side will be expanded to four lanes in the next several years through a TxDOT project that could include the 151/1604 interchange project that was stopped indefinitely last year.

4.7 miles of 1604 from Bandera to Culebra will be expanded to four lanes. At the moment, the Texas Department of Transportation is deciding between four different construction companies who will design and build the project.

On Tuesday, March 24, 1863, at Steele’s Bayou north of Confederate held Vicksburg, there was yet another skirmish near Black Bayou, as Federal gunships and troops continued their struggle to traverse numerous swamps and lowlands. 

This action effectively ended the Union attempt to traverse Steele’s Bayou, forcing the Union gunboats and troops withdrawing.  While annoying to the Confederates, the Union expedition proved little except the impracticality of using inland waterways to reach Vicksburg. 

Longtime Washington Post columnist and NPR political analyst E.J. Dionne Jr. spoke about his book, "Our Divided Political Heart," at 7 p.m. on March 19 at St. Mary’s University as part of the Lin Great Speakers Series.
