The nation's space agency is tearing down a rocket test stand in Huntsville that was once used by engineers working to send astronauts to the moon.
The National Aeronautics and Space Administration says workers will use explosives to demolish the concrete towers of Test Stand 4696 at Redstone Arsenal near Huntsville on Friday.
The 239-foot-tall tower was built in 1962 to test F-1 engines, which helped power Saturn V rockets to the moon. Documents show it hasn't been used since 1969, the year astronauts first landed on the lunar surface.
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.
Mercury is not the first planet to come to mind if you were searching for ice in the solar system. After all, the surface temperature across most of the planet is hot enough to melt lead.
But at the poles on Mercury it's a different story. Almost no sun reaches the poles, and as a result, temperatures can drop to less than -100 degrees Fahrenheit. Now, three papers in the journal Science suggest there really is ice at the bottom of craters near the poles on Mercury.
Spinach has lots of opportunities to pick up E. coli and other bugs during harvest and growing. Here, a Mexican migrant worker cuts organic spinach during the fall harvest at Grant Family Farms in Wellington, Co.
Salad producers haven't succeeded in banishing E. coli and other dangerous microbes from fresh greens, though they've tried hard. As we've reported before, it's a major challenge to both growers and the environment. But one scientist thinks he's making progress – with a spinach spa that zaps bad bugs with ultrasound.
The way some doctors see it, asking patients whether they own a gun is no more politically loaded than any other health-related question they ask.
So when a Florida law that prohibited them from discussing gun ownership with patients passed last year, they moved to fight it. A federal judge issued a permanent injunction blocking enforcement of the law in July.

Some people are allergic to peanuts, others to shellfish, fruits, or wheat. But this rare allergy is a carnivore's worst nightmare: A tick bite that can cause a case of itchy red hives every time you eat meat. Yup, get bit by one of these buggers and you may be saying farewell to your filet Mignon.
For some people around the country, this is no nightmare, it's a reality – and it may be coming to your neck of the woods.
In Washington, lawmakers are trying to work out a deal to keep the economy from going over the fiscal cliff. Many economists predict those automatic tax hikes combined with deep spending cuts set to go into effect on New Year's Day would throw the economy back into recession.
A group of top CEOs has been urging lawmakers to reach a deal to keep that from happening. Mark Bertolini is one of them. He's CEO of the health insurer Aetna and he said tax increases are as important as spending cuts. We called him to talk more.
Uncle Sam wants you to email your doctor. A federal law passed in 2009 says that physicians have to start offering their patients online communication, or Medicare will start docking how much it pays them in the future.
Some patients hope that having online access to their doctors will mean they can cut down on how often they have to go to the doctor's office. But fresh research suggests that patients with online access actually schedule more office visits.

A few months ago, I let you in on a little secret about Greek yogurt. Not all of this extra-thick, protein-rich yogurt is made the old-style way, by straining liquid out of it it. Some companies are creating that rich taste by adding thickeners, such as powdered protein and starch.
A light micrograph image of telomeres, shown in yellow, at the end of human chromosomes. Women tend to have longer telomeres than men and tend to outlive men, according to new research matching genetic information with medical records.
A massive research project in California is beginning to show how genes, health habits and the environment can interact to cause diseases. And it's all possible because 100,000 people agreed to contribute some saliva in the name of science.
Many teens aspire to have lean bodies and big muscles, like the professional athletes they so admire. But they don't always want (or know how) to sweat to get them. A new study finds a surprisingly high number of teens have used steroids to try to slim down and bulk up.
Six percent of teenagers say they've used steroid drugs in the past year, which is a lot higher than the 1.1 percent reported in a 2011 survey.
