They called it "the brick." And Martin Cooper says it really did look like one: 8 inches high, an inch and a half wide, 4 inches deep, and weighing 2 1/2 pounds.
In other words, the world's first hand-held cellphone, the Motorola DynaTAC, weighed the equivalent of about eight iPhones. (Try jamming that into a pocket.)
"The battery life was only 20 minutes," says Cooper, a former vice president at Motorola who has been called the "father of the cellphone." "But that was not a problem because you couldn't hold that heavy thing up for more than 20 minutes."
New York Mets pitcher R.A. Dickey delivers his signature pitch, with its unusual grip, against the Arizona Diamondbacks on May 6. He's the only knuckleballer in the major leagues, and the pitch has earned him a 12-1 record so far this season.
Silk is in neckties, scarves and some fancy underwear and pajamas. Before too long, it might just help keep people from getting sick with measles or polio.
Vaccines play an important role in health, but can be tricky to transport to the far corners of the world. Many vaccines and some other drugs require constant refrigeration — from the factories where they're made to the places where they're ultimately injected into people.

The Justice Department has unsealed criminal charges against four more people it says are connected to the death of U.S. Border Patrol Agent Brian Terry, as the FBI offered a $1 million reward for information leading to the capture of the fugitives.
Susan Clark (left) argues with another protester about the Affordable Care Act outside the U.S. Supreme Court. Chief Justice John Roberts likened the law's Medicaid expansion provision to "a gun to the head" of states.
Nothing breeds lawsuits like uncertainty. That being the case, the Supreme Court's landmark health care ruling is almost certain to open the door to lawsuits challenging the federal government's authority.
The court ruled the federal government can't force states to participate in a major expansion of Medicaid or else risk losing existing Medicaid funds from Washington. That threat amounted to unconstitutional coercion.
The southern African nation of Botswana is grappling with a relatively new problem in the evolving AIDS pandemic: It now has a large group of HIV-positive adolescents.
The teenagers were infected at birth before Botswana managed to almost wipe out mother-to-child transmission of the virus. These children have survived because of a public health system that provides nearly universal access to powerful anti-AIDS drugs.
