Alabama's northern counties are under a flood watch as potentially heavy rains move into the state. The National Weather Service says storms crossing into the Tennessee Valley will bring rainfall totals from 1 to 3 inches by Tuesday, as some areas could receive as much as 5 inches of rain. The heaviest precipitation is expected to fall overnight Monday. Forecasters say northeastern Alabama should receive the heaviest rains. The weather service says streams along the Tennessee River will rise because of runoff from the storms. / Tennessee Valley Authority

The Tennessee Valley Authority plans to add around 100 jobs at its Browns Ferry Nuclear Plant in the next year. The plan, announced Wednesday, is part of an effort to improve performance and safety. TVA chief nuclear officer Preston Swafford says officials will probably start the hiring process in a couple of months. Keith Polson, Browns Ferry site vice president, says the new jobs will involve various specialties such as engineering, maintenance, radiation protection, chemistry, work control and emergency planning.

Death Toll Climbs In Congo Ebola Outbreak

Sep 13, 2012

As health workers try to contain an Ebola outbreak in the Democratic Republic of the Congo, the death toll has increased to 31.

The deaths from the hemorrhagic fever outbreak doubled in the past week. World Health Organization spokesman Tarik Jasarevic tells Shots that's because they have discovered more people who were originally infected.

Fast food giant McDonald's announced a big move yesterday to begin posting calories on menu boards. It's also making smaller changes designed to help Americans make healthier choices; smaller changes you might not even notice.

But NPR's Allison Aubrey reports they can make a real difference.

There's no ready euphemism for this, so be warned.

The New York City Board of Health voted unanimously today in favor of a new regulation that would require parents of young boys who undergo ritual circumcisions involving "direct oral suction" to sign a consent form first.

To protect children against whooping cough, doctors recommend five shots of vaccine before they turn 7.

But what happens after that? How long does the protection last?

Beginning next week, McDonald's plans to add calorie counts to its menu boards — both at drive-thrus and restaurant counters. Studies suggest that calorie boards alone don't change consumers' purchasing patterns. But consumers do seem to take note, and public health experts say it's one tangible step to helping consumers make healthier choices.

The numbers for West Nile virus cases continue to rise, up 35 percent in the last week. But the Centers for Disease Control and Prevention is confident the nation has turned the corner on its worst-ever epidemic of West Nile virus disease.

Arctic sea ice has melted dramatically this summer, smashing the previous record. The Arctic has warmed dramatically compared with the rest of the planet, and scientists say that's what's driving this loss of ice.

To be sure, ice on the Arctic Ocean always melts in the summer. Historically, about half of it is gone by mid-September. But this year, three-fourths of the ice has melted away, setting a dramatic new benchmark.

Scientific testing has confirmed a link between oil from the massive BP spill and tar found on Alabama beaches after Hurricane Isaac. Auburn University researcher Joel Hayworth said Tuesday a chemical analysis showed that tar balls collected after Isaac were associated with the type of oil spilled after the explosion on the Deepwater Horizon rig in 2010. Auburn researchers collected about 15 pounds of tar balls after the storm, and officials from Gulf Shores and Orange Beach picked up still more.

NFL Charities is awarding more than $1.5 million in grants for sports-related medical research at 15 organizations, with nearly two-thirds of the money going to study concussion prevention and treatment. This year's grants include research on stem cells and nervous system injuries; MRI methods after concussions; and the effect of temperature on the severity of potential brain injuries.

The health care overhaul law makes it easier for most people with private insurance to get the vaccines they need without going into their pockets for a copay. Medicare beneficiaries don't get the quite same sweet deal, though.

Flu pandemics don't happen very often. So many people might feel the relative fizzle of a flu pandemic three years ago somehow immunizes the globe against another one for awhile.

But don't relax, say the authors of a report published online in the Proceedings of the National Academy of Sciences.

The current poster child for global warming is a polar bear, sitting on a melting iceberg. Some health officials argue the symbol should, instead, be a child.

That's because emerging science shows that people respond more favorably to warnings about climate change when it's portrayed as a health issue rather than as an environmental problem.

If you're dieting, you know you've got to count calories, carbs and fats. But if you really want to take off the weight and keep it off, you might want to pay more attention to the glycemic index, which is essentially a measure of how quickly foods are digested.

The nation is in the midst of a kidney stone epidemic.

New research shows 1 in 10 American men and 1 in 14 women has had one. And prevalence of kidney stones has shot up in recent years.

Rains Improving Drought Conditions In Alabama

Sep 7, 2012 / National Drought Mitigation Center

Heavy rains have helped ease drought conditions in Alabama, but about one-third of the state remains unusually dry. The latest update from the U.S. Drought Monitor shows about two-thirds of the state is drought-free, a big improvement from just a few weeks ago. But a third of the state remains abnormally dry or in a drought. Dry conditions cover a wedge-shaped area extending from the Hale-Bibb county line eastward to the Georgia line. Conditions are worst in about a dozen counties that include the Auburn area.

Researchers report that women with genetic mutations that put them at dramatically increased risk of developing breast cancer may also face a heightened risk from radiation used during medical screening and diagnosis.

The imaging tools that help doctors identify disease, injury or damage to the body have long been known to carry some risk of cancer, in large part because ionizing radiation can damage the genetic material in the body.

San Francisco is trying a new tactic to fight AIDS. Health workers are aggressively testing people for HIV and then immediately putting those who test positive on potent antiretroviral drugs.

BP Says Old Oil From Spill Exposed By Isaac

BP says Hurricane Isaac's scouring waves exposed deposits of buried tar on the Louisiana coast that were left over from its massive oil spill in 2010. Louisiana officials closed a stretch of beach near Fourchon on Tuesday after scouts said they found large tar mats. BP acknowledged Wednesday the oil was from its spill.

UAB Sports Medicine / Children's Hospital of Alabama.

It's football season and for many young athletes that means lots of practices and training to get in shape for the big game every week. It's also a prime time for these players to get injured. Drew Ferguson is a licensed athletic trainer and Director of Sports Medicine at Children's Hospital of Alabama. Ferguson says extra care needs to be taken at youth levels to keep players safe because they lack the resources of the older counterparts.

An estimated 14.9 percent of U.S. households — 17.9 million in total — "had difficulty" at some point last year getting food because they just didn't have enough money or other resources, the U.S. Department of Agriculture reported this morning.

In 2010, 14.5 percent of households were similarly "food insecure" at some point, USDA says.

Even worse:

Flooding Causes Damage In West, South Alabama

Sep 4, 2012

Flooding caused by remnants of Hurricane Isaac has caused extensive damage in parts of western and southern Alabama.

Swirling water lapped at the doors of businesses in downtown Selma. At least 20 cars filled with quick-rising water at an automotive dealership before workers could move them.

In Gordo, about two dozen houses were flooded, two bridges were washed out and several families had to be rescued in the town of 1,750 people.

And a commissary that provides food for thousands of elderly people in western Alabama filled with about a foot of water in Brent.

After decades of encouragement, Americans are getting their blood pressure checked more often.

And there's a little more good news, according to the Centers for Disease Control and Prevention. Most adults with high blood pressure are being treated these days.

But, and you knew there had to be a but, more than half of all Americans with hypertension — about 36 million people, all told — still haven't got it under control.

McDonald's Goes Vegetarian — In India

Sep 4, 2012

McDonald's, home of the iconic Big Mac, is going vegetarian. Well, at least in India, where 20 to 42 percent or more of the population (depending on how you count) eschews meat, according to the Food and Agriculture Organization.

A growing number of companies are changing their health insurance plans to include benefits for transgender employees.

Yet even though professional groups such as the American Medical Association recommend coverage of services for transgender people —who identify with a gender other than the one they were born as—many companies continue to hold back. One of their big worries is cost.

Yes, organics is a $29 billion industry and still growing. Something is pulling us toward those organic veggies that are grown without synthetic pesticides or fertilizers.

But if you're thinking that organic produce will help you stay healthier, a new finding may come as a surprise. A new study published in the Annals of Internal Medicine finds scant evidence of health benefits from organic foods.

This paragraph from NASA worried us:

"In one study, astronomers used WISE to identify about 2.5 million actively feeding supermassive black holes across the full sky, stretching back to distances more than 10 billion light-years away. About two-thirds of these objects never had been detected before because dust blocks their visible light. WISE easily sees these monsters because their powerful, accreting black holes warm the dust, causing it to glow in infrared light."

Scientists have known for decades that lab rats and mice will live far longer than normal if they're fed a super-low-calorie diet, and that's led some people to eat a near-starvation diet in the hopes that it will extend the human life span, too.

But a new study in monkeys suggests they may be disappointed.

The long-awaited results of this study, which started back in 1987, show that rhesus monkeys fed a diet with 30 percent fewer calories than normal did not live unusually long lives.
