In Istanbul, major public transit projects are back under way after years of paralysis. The problem wasn't a lack of financing, but the layer upon layer of ancient artifacts that turned up every time the earthmovers started their work.

The excavation began eight years ago on projects intended to ease Istanbul's notoriously clogged traffic.

The job included building a tunnel under the Bosphorus Strait and linking it to a rail and subway network. When the dig was stopped several years ago, eyes rolled and shoulders shrugged.

Life is hard for albinos throughout Africa, but especially in the East African nation of Tanzania. At best, they face raw prejudice; at worst, they are hunted for their flesh, the results of superstitious beliefs.

Albino killings have been reported in a dozen African countries from South Africa to Kenya, but they are worse in Tanzania than anywhere else.

Superstorm Sandy sparked a lot of interest in rising sea levels when it swept across the Northeast last month and flooded parts of the coast. Over the next century, more water — and higher sea levels — could come from melting ice in Greenland and Antarctica. How much has been unclear.

But now scientists have developed a much clearer view of how quickly that ice has been melting over the past two decades. And that will help researchers forecast the rate of sea-level rise in the years to come.

Before Secretary of State Hilary Rodham Clinton passes the reins to her successor, she's got a few loose ends to tie up. One of them is mapping out the U.S.'s continuing efforts to combat AIDS around the world.

Now Clinton isn't talking about ending the HIV pandemic altogether. Rather, she hopes to prevent most new infections from occurring in the first place and to stop HIV-positive people from developing AIDS.
