Scientists say Haiti could be hit by another earthquake soon

The chance of another big earthquake in Haiti in the near future is great enough that people in Port-au-Prince should sleep in tents, geologists said Monday. The probability of an aftershock of magnitude 7 or greater in Haiti in the next 30 days is 3 percent, the probability of one magnitude 6 or greater is 25 percent, and of one magnitude 5 or greater is about 90 percent, according to a report by the United States Geological Survey. | 02/02/10 07:05:55 By - Fred Tasker

A 7.0 quake in South Carolina? Not impossible, scientists say

A new state-of-the-art radar system on the Washington coast will make it easier for meteorologists to track heavy weather coming off the Pacific Ocean, as some scientists say the intensity of winter storms and waves pounding the Northwest shore is increasing. | 01/10/10 00:01:00 By - Les Blumenthal

Dust: Tiny particles with a big impact

Dust is everywhere, burrowing under beds, piling up on windowsills, clogging guns and machinery, irritating eyes, noses and lungs. It soars thousands of miles over continents and oceans, sometimes obliterating the sky. Now scientists are beginning to have new respect for the way dust alters the environment and affects the health of people, animals and plants. | 12/30/09 14:45:00 By - Robert S. Boyd

A plethora of numbers traces a decade of change

At the beginning of the decade, the median average household income in the United States was $44,900, and Bill Gates, running Microsoft, then America's most valuable business, was worth an estimated $85 billion. As the first decade ends, the median average income, adjusted for inflation, is down to $38,924 and Gates' inflation-adjusted net worth is just $38.5 billion. Exxon Mobil has supplanted Microsoft as the country's most valuable company. | 12/29/09 15:48:00 By -

Florida avocado growers fear spread of exotic Asian beetle

The redbay ambrosia beetle has been discovered in Florida's Martin County afer sweeping through the Carolinas and Georgia.

Studies indicate CT scans might cause cancer

Two studies in the United States have found that radiation from computed tomographic (CT) scanners may cause cancer long after patient exposure. Researchers from the University of California, San Francisco, found that CT scans emit higher levels of radiation than was thought at first. A separate study done by the National Cancer Institute estimated that radiation from more than 70 million CT scans performed in the United States in 2007 will ultimately cause about 29,000 cases of cancer, and a possible 15,000 deaths. | 12/22/09 11:41:18 By - Carol Reiter

Winter's arrived, which in Alaska means spring is coming

Between the winter solstice and Jan. 1, Anchorage will pick up one minute more of daylight every day as the sun sets later. On Jan. 2, dawn will begin coming earlier as well, meaning that while the rest of the United States has just seen winter arrive, Alaskans are seeing spring on the horizon. | 12/21/09 14:10:30 By - Rosemary Shinohara

Arctic research pushes scientists to extremes

If you want to know how polar bears are doing, it's not enough to spy on them with satellite telemetry and other technology. You have to go where they live. To get some answers, they traveled to a part of the world few get to see, and far fewer get to see from beneath the sea ice. Or would want to. | 12/21/09 06:33:56 By - Debra McKinney

Adult stem cells may help repair hearts, study finds

Adult stem cells might help repair hearts damaged by heart attack — in part by becoming heart cells themselves. That was the finding of a new study, released Monday, that points to a promising new treatment for heart-attack patients that could reduce mortality and lessen the need for heart transplants. Adult stem cells also could help heal livers, kidneys, pancreases and other organs. | 12/01/09 07:01:55 By - Fred Tasker

Stakes are high as doubt is cast on forensic lab techniques

Experts: Careless work of Texas medical examiners costly

Over the years, Texas medical examiners have misidentified bodies, botched examinations and had to do a double take on cases of individuals later exonerated by law enforcement. That has opened the door for innocent men and women to go to prison and killers to go free.

Do TV medical shows provoke higher health costs?

Pushing medical practice to the extreme may be the cost of keeping viewers hooked on Fox's hit show, which dramatizes the diagnoses of rare maladies.

Blame the EPA: Lead mining threat lingers in a Kansas town

The Environmental Protection Agency has bought out the residents of Picher, Okla., because of the remaining threat from leftover lead tailings and cave-ins from the mining industry that essentially collapsed in 1970.

Older people not on priority list for swine flu vaccinations

Pregnant women, children and people who have certain health conditions are considered the most vulnerable to complications from the new flu virus, and they will be given priority for the shots this fall. Older people, who are among the hardest hit for seasonal flu, are not on the list. They appear to have some immunity to the new bug, perhaps from exposures to related H1N1 viruses that circulated before 1957. | 07/30/09 06:45:02 By - Sarah Avery

Big, mysterious blob floating off Alaska coast? It's algae

A sample of the giant black mystery blob that hunters discovered this month floating in Alaska's Chukchi Sea has been identified. Not bunker oil seeping from an aging, sunken ship. Not a sea monster. It looks to be a stringy batch of algae. | 07/17/09 15:29:00 By - Kyle Hopkins

Gravity wells could provide 'parking lots' for spaceships

Some NASA folks call them "parking lots" in space. They're unusual locations where gravity loses its pull and a spaceship can loiter, rather like a marble at the bottom of a cup, without using a lot of fuel. Three of them are 930,000 miles outside Earth's orbit. One is between the Earth and the sun, and another is hidden on the far side of the sun. | 07/14/09 15:45:00 By - Robert S. Boyd

Dallas hospital to study estrogen's effect on traumatic brain injuries

Energy bill nears vote in House, but what's in it for consumers?

How much will it cost the average American household to reduce the U.S. share of global warming pollution and shift to cleaner sources of energy produced at home?

Projection: It'll be years before jobs return to much of U.S.

Unlike the labor market collapse that killed millions of U.S. jobs in a matter of months, the nation's return to peak employment will not be nearly as uniform nor as swift. While signs indicate that the worst of the recession may be over, only six metropolitan areas across the country are expected to regain their pre-recession employment levels by the end of 2009, according to projections from IHS Global Insight, a leading economic forecaster. | 06/14/09 06:00:00 By - Tony Pugh

Texas wind farms deploy radar so birds, not feathers, can fly

Some GPS satellites could fail before replacements arrive

GPS satellites originally scheduled to head skyward in 2006 in a $7 billion-plus program aimed at keeping the system going are awaiting launch in 2010. The delay means pieces of the high-altitude network could start falling out of service as early as next year.

Zombie fire ants wander in Texas — until heads fall off

It sounds like something out of science fiction: zombie fire ants. But it's all too real. Fire ants wander aimlessly away from the mound. Eventually their heads fall off, and they die.

Researchers can't agree on severity of swine flu outbreak

More than a month into the swine flu outbreak that has now affected 13 countries, medical experts are wondering aloud whether the contagious disease will ever become the deadly pandemic that everyone fears.

Progress: Cheap pens that write right (and don't smear)

Disposable pens used to be things you wanted to dispose of by throwing them across the room. They skipped. They had to be muscled across the page.
