More older adults living with HIV/AIDS

The miracle of growing old was all but unimaginable for them 30 years ago, at the dawn of the age of AIDS. But today the number of people 50 and older diagnosed with HIV or living with AIDS is booming. According to the federal Centers for Disease Control, people who are 50 and older account for more than 15 percent of the nation's new HIV diagnoses. That percentage is expected to double within the next four years, making older adults America's fastest growing HIV demographic. | 07/15/11 06:23:17 By - Anita Creamer

Was FBI too quick to judge anthrax suspect the killer?

Scouring the anthrax-laced mail that took five lives and terrorized the East Coast in 2001, laboratory scientists discovered a unique contaminant — a tiny scientific fingerprint that they hoped would help unmask the killer. Yet once FBI agents concluded that the likely culprit was Bruce Ivins, they stopped looking for the contaminant. That decision could reignite the debate over whether its agents found the real killer. | 04/20/11 17:11:00 By - Greg Gordon

Researchers confirm subsea Gulf oil plumes are from BP well

Through a chemical fingerprinting process, researchers have definitively linked clouds of underwater oil to BP's runaway Deepwater Horizon well — the first direct scientific link between the subsurface oil clouds commonly known as "plumes" and the BP oil spill. The finding confirms what in the early days of the spill was denied by BP and viewed skeptically by NOAA — that much of the crude from the Deepwater Horizon well stayed beneath the surface of the water. | 07/23/10 21:10:00 By - Sara Kennedy

Gulf's oil slick, already waning, could vanish with the wind

Starved of its daily dose of crude and under assault by wind, waves, sun, oil-eating bacteria and the largest fleet of oil skimmers ever assembled, the massive oil slick that has stalked the Gulf of Mexico for three months has been shrinking for the past week. Now, a blustery tropical system expected to hit the main spill area Saturday could literally blow much of the slick's remnants away. | 07/23/10 20:06:00 By - Curtis Morgan

Amid leak worries, feds and BP focus on killing Gulf well

The government and BP continue to monitor leaks that appeared this weekend to be an ominous threat to their effort to contain the gush of oil in the Gulf of Mexico. But they've also renewed their focus on permanently capping the well that killed 11 people, fouled the Gulf of Mexico and wreaked economic havoc on the region. | 07/19/10 19:42:00 By - Erika Bolstad

Duke scientist placed on leave over Rhodes Scholar claim

A well-regarded Duke University cancer researcher has been placed on leave and at least temporarily denied access to a research grant while the university investigates whether he falsely claimed to be a Rhodes Scholar on applications for federal funding. | 07/17/10 18:27:43 By - Eric Ferreri

BP continues tests, but can't guarantee cap will succeed

BP will proceed with its delicate testing of its containment cap that could continue to keep oil from spewing into the Gulf of Mexico from its failed well, but the team monitoring the testing isn't 100 percent confident the cap will be successful. | 07/16/10 20:29:00 By - Erika Bolstad

Despite Gulf cleanup efforts, nature will have to do most of it

Now that BP has shut off oil flowing into the Gulf of Mexico from its broken well for the first time in 12 weeks, the company faces a Herculean task of cleaning up the region's oily mess. | 07/16/10 18:15:00 By - Renee Schoof

Here's some hope for Gulf: Spill-eating microbes spike

The number of naturally occurring microbes that eat methane grew surprisingly fast inside a plume spreading from BP's ruptured oil well, an oceanographer who was one of the first to detect the plumes said Tuesday. | 07/13/10 18:11:00 By - Renee Schoof

His mission: save the planet's oceans

John Bruno is now at the center of international debate about the health of the oceans, co-writing a sweeping account of the problems in last month's issue of the journal Science. His conclusion — that global climate change is putting the world's largest ecosystem in peril — has added to a growing level of alarm about oceans. | 07/11/10 14:21:24 By - SARAH AVERY

FDA nears approval of genetically engineered salmon

They may not be the 500-pound "Frankenfish" that some researchers were talking about 10 years ago, but a Massachusetts company says it's on the verge of receiving federal approval to market a quick-growing Atlantic salmon that's been genetically modified with help from a Pacific Chinook salmon. | 07/11/10 00:01:00 By - Les Blumenthal

Scientists urge U.S. to move quickly to study Gulf oil spill

Frustrated with limited data on the BP oil gusher, a group of independent scientists has proposed a large experiment that would give a clearer understanding of where the oil and gas are going and where they'll do the most damage. Thye say their mission must be undertaken immediately, before BP kills the runaway well. | 07/08/10 18:18:00 By - Renee Schoof

Weedkiller takes a toll on nation's oldest grape vine

For centuries, a massive grapevine has grown on the northern end of Roanoke Island in North Carolina, surviving nor'easters, bugs and mildew for maybe 400 years. Then a utility contractor sprayed it with weedkiller. | 07/05/10 17:11:49 By - Bruce Henderson

Judges rule Obama can't close Yucca Mountain nuclear dump

Three administrative judges within the Nuclear Regulatory Commission ruled last week that Congress designated Yucca Mountain in 1987 to receive highly toxic waste and that only an act of Congress can close it. President Obama and Energy Secretary Steven Chu cannot withdraw the government's application to dump waste there. | 07/04/10 05:34:16 By - James Rosen

BP wasted no time preparing for oil spill lawsuits

In the immediate aftermath of the Deepwater Horizon disaster, BP publicly touted its expert oil clean-up response, but its preparations for the legal fight to come was what really impressed. In a matter of days, BP signed up experts who otherwise would work for plaintiffs, shopped for top-notch legal teams and drew up waivers for volunteers, fishermen and workers that would take away some of their right to sue. | 07/03/10 15:52:00 By - Marc Caputo

Another Gulf mystery: Who's in charge of oil spill research?

As an unprecedented amount of oil fouls the Gulf of Mexico, research scientists and ocean experts say the Obama administration's efforts to discover the magnitude of the damage are surprisingly uncoordinated. | 07/02/10 15:36:00 By - Renee Schoof

EPA says more testing needed to know dispersants' impacts

The first round of government tests of the chemical dispersants that are being used to break up the massive oil spill in the Gulf of Mexico found that they aren't overly damaging to shrimp and small fish, but more tests are needed to determine what happens when they're mixed with oil. | 06/30/10 19:47:00 By - Renee Schoof

Health of Exxon Valdez cleanup workers was never studied

You'd think that more than 20 years after the Exxon Valdez oil spill, scientists would know what, if any, long-term health dangers face the thousands of workers needed to clean up the Gulf of Mexico spill. You'd be wrong. | 06/29/10 19:55:00 By - Kyle Hopkins

Mississippi officials slam Coast Guard as BP oil hits shores

What South Mississippi officials had been fearing for weeks came true Sunday when large, gooey globs of weathered oil, chocolate-colored oil patties and tar balls washed ashore in quantity along the Mississippi Coast. Local officials were livid, saying the Coast Guard and BP had failed to move fast enough Saturday, even though it was apparent the oil was heading toward the shoreline. | 06/27/10 22:19:28 By - Anita Lee and Margaret Baker

Louisiana applauds judge's offshore drilling ruling

The oil industry employs 32,000 people in Louisiana's coastal parishes and pumps an estimated $3 billion into the state economy. In cities like Houma in Terrebonne Parish, more than 60 percent of the jobs are oil-related. So when U.S. District Judge Martin Feldman ruled last week that the Obama administration had overstepped its authority by ordering a six-month moratorium on deep water drilling in the Gulf of Mexico, he became a folk hero. | 06/27/10 18:17:00 By - Lesley Clark and Robert Samuels

BP played big role in Alaska blowout preventer probe

When two Alaska state agencies received complaints in 2005 that a BP drilling contractor routinely cheated on tests of blowout preventers and that BP knew it, the agencies let both companies join the investigation. In at least three instances, after witnesses confirmed allegations, company lawyers took them aside for private conversations. One witness recanted his statement immediately after emerging from his private meeting with a company attorney, state records show. | 06/26/10 17:03:00 By - Richard Mauer

Arctic drilling still a no-go, despite judge's moratorium ruling

The ruling by a federal judge in New Orleans overturning an offshore drilling moratorium in the Gulf of Mexico does not affect the Interior Department's decision not to consider applications to drill in the Arctic until 2011. | 06/22/10 19:17:46 By - Erika Bolstad

Are Australian honeybees behind U.S. hive collapse?

Disease-carrying honeybees imported from Australia may be responsible for a mysterious disorder that's decimated bee hives around the country, and federal regulators say they'd consider import restrictions if necessary. | 06/20/10 00:01:00 By - Les Blumenthal

MMS blasted for lax offshore drilling scrutiny

The Minerals Management Service, the beleaguered regulator caught in the crosshairs over its faulty scrutiny of BP's runaway oil well in the Gulf of Mexico, has been lax in its inspections of deep-sea drilling, an independent watchdog said Thursday. | 06/17/10 18:42:00 By - Reid Davenport

BP's Gulf leak boosts interests in oil-eating microbes

One scientist compares the microbes to the yellow chompers in the Pac-Man video game — hungry and single-minded as they gobble hydrocarbons from the oily waters, marshes and shores of the Gulf of Mexico. | 06/17/10 18:11:25 By - Fred Tasker

BP's oil recovery stats show how wrong leak estimates were

BP recovered 18,600 barrels of oil from its gushing Deepwater Horizon well on Wednesday, the most so far, but still just a fraction of what is spewing into the Gulf of Mexico. The amount serves as a reminder of the weeks-long reluctance of both BP and the Obama administration to recognize the full extent of the disaster. | 06/17/10 13:19:45 By -

Newest oil spill flow rate: 35,000 to 60,000 barrels daily

The runaway Deepwater Horizon well is pouring 35,000 to 60,000 barrels a day of oil into the Gulf of Mexico, the Obama administration said Tuesday. Energy Secretary Steven Chu, however, warned that the estimate is still preliminary, and that it might be revised upward. | 06/15/10 17:38:15 By - Renee Schoof

Plan to burn excess oil from BP well raises health questions

Plans to burn hundreds of thousands of gallons of oil from BP's blown-out well are raising new questions about the health and safety of the thousands of workers on rigs and vessels near the spill site. | 06/11/10 18:53:00 By - Renee Schoof and Marisa Taylor
