What will a gallon of milk set you back? How about a new car? You probably have a rough idea.
But what about a new knee or a hip replacement? Chances are you have no clue. And you aren't alone. The surgeons who implant the devices probably don't know either, a survey finds.
Medicare spends about $20 billion each year on implanted medical devices. Nearly half of the total goes to orthopedic procedures. As the population ages and more Americans get joint replacements, the spending on implants is likely to keep rising.
The unmarked, unpaved streets of Juba, the capital of South Sudan, can be tough for an outsider to navigate.
By the time I found the house of Peter Adwok Nyaba, the country's former minister of higher education, science and technology, it was already 5 p.m. The sun was dangerously low on the horizon. I had less than an hour to interview Adwok and get back to my hotel before the citywide curfew โ imposed when the violence began three weeks before โ took effect. After 6, there would be no one on the streets except myself and soldiers.
Britain's southwest coast is getting slammed by a winter storm, with high winds driving waves as high as 27 feet ashore in an unusual event that meteorologists say is likely linked to the bone-chilling "polar vortex" gripping much of the U.S.
In Lisbon, the waiting area of Portugal's biggest maternity hospital is empty. You can hear the hum of soda machines across the hall. There's just one expectant father, pacing the room.
Mario Carvalho, 40, has a toddler son and now awaits the birth of his baby girl.
"Today, I hope!" he says with a nervous smile.
The birth of a new baby is a joyous occasion. But in Portugal, it's an increasingly rare one. Since the economic crisis hit, the country's birthrate has dropped 14 percent, to less than 1.3 babies per woman โ one of the lowest in the world.
European scientists were alarmed in 2008 when they discovered streams of methane bubbles erupting from the seafloor in Norway's high Arctic. This gas, which contributes to global warming, was apparently coming from methane ice on the seafloor. A follow-up study finds that methane bubble plumes at this location have probably been forming for a few thousand years, so they are not the result of human-induced climate change. But continued warming of ocean water can trigger more methane releases in the Arctic, with potentially serious consequences to the climate.
The U.S. Forest Service has proposed a large salvage logging operation in the area affected by last year's historic Rim Fire, which burned 410-square miles of California's Sierra Nevada. The proposal is meeting stiff opposition from environmental groups who say the land is better left untouched.

It's -16 degrees today here in Chicago, which for many of us has triggered hibernation mode. Fortunately the great Jerry's Sandwiches has created the Ignatius R., with enough calories to get us to the end of winter, which we expect to occur sometime in August.

Frostbite isn't usually a major worry here in Washington, D.C., but with wind chills below zero forecast for half of the Lower 48 by Tuesday morning, millions of people from the Plains to the East Coast will have to start thinking like Arctic explorers while waiting for a school bus or heading to work.
Noses, fingers, toes and ears face the biggest risk. Those body parts have less blood flowing through them and a lot less mass than the body's core. They're also more likely to be exposed to the elements. Obviously, bundling up those tender parts is key.
