(AP) — Heart-clogging trans fats were once a staple of the American diet, plentiful in baked goods, microwave popcorn and fried foods. Now, mindful of the health risks, the Food and Drug Administration is getting rid of what's left of them for good.

The FDA announced Thursday it will require the food industry to gradually phase out artificial trans fats, saying they are a threat to public health.

Thanks to criticism from the medical community and number of local laws, many trans fats have been taken out of the food supply already. But the FDA said Thursday that getting rid of the remainder — the average American still eats around a gram of trans fat a day — could prevent an additional 20,000 heart attacks and 7,000 deaths each year.

"While consumption of potentially harmful artificial trans fat has declined over the last two decades in the United States, current intake remains a significant public health concern," said FDA Commissioner Margaret Hamburg.

The agency isn't yet setting a timeline for the phase-out, but it will collect comments for two months before officials determine how long it will take. Different foods may have different timelines, depending how easy it is to find a substitute.

"We want to do it in a way that doesn't unduly disrupt markets," said Michael Taylor, FDA's deputy commissioner for foods. Still, he says, the food "industry has demonstrated that it is, by and large, feasible to do."

Scientists say there are no health benefits to trans fats and they can raise levels of so-called "bad" cholesterol and lower "good" cholesterol, increasing the risk of heart disease — the leading cause of death in the United States. Trans fats are widely considered the worst kind for your heart, even worse than saturated fats, which also can contribute to heart disease.

Trans fats are used both in processed food and in restaurants, often to improve the texture, shelf life or flavor of foods. Though they have been removed from many items, the fats are still found in some processed foods, including in many baked goods like pie crusts, biscuits and ready-to-eat frostings that use the more-solid fats to keep consistency.

They are also sometimes used by restaurants that use the fats for frying. Many larger chains have phased them out, but smaller restaurants may still get food containing trans fats from suppliers.

To phase them out, the FDA said it had made a preliminary determination that trans fats no longer fall in the agency's "generally recognized as safe" category, which is reserved for thousands of additives that manufacturers can add to foods without FDA review. Once trans fats are off the list, anyone who wants to use them would have to petition the agency for a regulation allowing it, and that would likely not be approved.

The fats are created when hydrogen is added to vegetable oil to make it more solid, which is why they are often called partially hydrogenated oils. The FDA is not targeting small amounts of trans fats that occur naturally in some meat and dairy products, because they would be too difficult to remove and aren't considered a major public health threat on their own.

Many companies have already phased out trans fats, prompted by new nutrition labels introduced by FDA in 2006 that list trans fats and an by an increasing number of local laws, like one in New York City, that have banned them. In 2011, Wal Mart pledged to remove all artificial trans fats from the foods the company sells by 2016.

In a statement, New York City Mayor Michael Bloomberg said it was his city's 2007 ban that prompted much of the progress. "Our prohibition on trans fats was one of many bold public health measures that faced fierce initial criticism, only to gain widespread acceptance and support," he said.

Indeed, consumers have slowly eaten fewer of the fats. According to the FDA, trans fat intake among American consumers declined from 4.6 grams per day in 2003 to around one gram per day in 2012. And a handful of other countries have banned them as well, including Switzerland and Denmark. Other countries have enacted stricter labeling laws.

Dr. Leon Bruner, chief scientist at the Grocery Manufacturers Association, said in a statement his group estimates that food manufacturers have voluntarily lowered the amount of trans fats in food products by 73 percent.

The group, which represents the country's largest food companies, did not speculate on a reasonable timeline or speak to how difficult the move may be for some manufacturers. Bruner said in a statement that "consumers can be confident that their food is safe, and we look forward to working with the FDA to better understand their concerns and how our industry can better serve consumers."

FDA officials say they have been working on trans fat issues for around 15 years — the first goal was to label them — and have been collecting data to justify a possible phase-out since just after President Barack Obama came into office in 2009.

The advocacy group Center for Science in the Public Interest first petitioned FDA to ban trans fats nine years ago. The group's director, Michael Jacobson, says the move is "one of the most important lifesaving actions the FDA could take."

He says the agency should try to move quickly as it determines a timeline.

"Six months or a year should be more than enough time, especially considering that companies have had a decade to figure out what to do," Jacobson said.

AP Photos: Nashville turns up the glamour at CMAs


Country music stars were all dressed up with somewhere to go: the Country Music Awards.

The event in Nashville, Tenn., on Wednesday night was another chance for Taylor Swift to be belle of the ball and this time she did it in a bateau-neck red gown with embroidery and a thin leather belt by Elie Saab.

But there were other stars who took this moment in the spotlight to shine — in sequins and baubles — including Jennifer Nettles, who wore a crystal-and-mirror beaded gown by Naeem Khan on the red carpet and a Georges Chakra blush-colored beaded jumpsuit onstage.

Carrie Underwood did several outfit changes. Among them: She wore a midnight-blue gown with white porcelain cherry blossoms by Theia and a short, black tuxedo-style romper by Chagoury decorated with Swarovski crystals.

Kacey Musgraves went with a short-hemline head turner, choosing a yellow handkerchief dress by Sally LaPointe for her performance. Earlier she was in a Blumarine outfit with a short dress under a long, sheer floral overlay. Kimberly Perry of The Band Perry did the short-long switch, too, in a 14-karat gold and sterling mesh mini by Rubin Singer when she was singing and a more delicate ivory-colored embroidered gown for the arrivals line.

Connie Britton did her own two-in-one turn in a Georges Hobeika gown that had a demure black-beaded collar and a slim, sexy bodice.

DETROIT (AP) — A convicted felon who was wearing body armor when police arrested him in a Detroit suburb will be questioned in an investigation into the fatal shooting of three men in a back gambling room of an east side barbershop.

Detroit Police Chief James Craig described the man as a person of interest in Wednesday evening's shooting at Al's Barber Shop that left six other people wounded. Speaking at a Thursday news conference at police headquarters, Craig said the bloodshed may have stemmed from an ongoing feud.

Craig did not name the person of interest and provided few details about the arrest. He said Rochester police picked up the man north of Detroit without incident on an unrelated felonious assault charge.

"Police wear body armor. Why would a community member be driving around in body armor?" said Craig, who described the latest mass shooting in Detroit as "urban terrorism."

Craig said 20 to 30 people were gambling in a tiny back room at the barbershop in a strip mall shortly before 6 p.m. when shots were fired from a high-powered rifle through an open back door.

When the gunfire began, the gamblers tried to escape the room through a door that led back into the barbershop, but that the jam of bodies prevented them from escaping.

"The shooter struck nine of the individuals inside the location," Craig said, adding that many people in the room were armed and at least one returned fire.

"Officers were able to develop information that there was an ongoing feud between a particular individual and several members of the gambling party," the chief said.

Craig declined to say whether police think the person of interest is the shooter. But he would say that the shooter is suspected in at least two other violent crimes.

Two of Wednesday's shooting victims died inside the gambling room. The third died later at a hospital. The conditions of the survivors were not available.

A witness told police that the shooter pulled into a rear alley and fired shots at someone in a pickup truck. He then got out of the car and began shooting into the open rear door of the barbershop.

Wednesday night police said they were seeking two vehicles believed to have been involved in the shooting.

Lorne Carter told the Detroit Free Press that he was smoking a cigarette against the wall of a nearby business when he heard what sounded like 30 to 40 rapid shots.

Detroit has one of the highest violent crime rates in the country. Including Wednesday night's barbershop slayings, 289 criminal homicides have been committed so far this year in Detroit.

Criminal homicides accounted for 386 of the 461 death investigations in 2012.

"Anytime you have ... shootings of nine, it certainly does rise up as one of Detroit's more violent incidents," Craig said.

Craig said one person was shot and three others wounded during a shooting in October 2012 on the city's west side. Seven teenagers — including five students at Cody Ninth Grade Academy — were shot and wounded while waiting at a bus stop near that school in June 2009.

Discovering a new species is, among biologists, akin to hitting a grand slam, and University of South Carolina ichthyologist Joe Quattro led a team that recently cleared the bases. In the journal Zootaxa, they describe a rare shark, the Carolina hammerhead, that had long eluded discovery because it is outwardly indistinguishable from the common scalloped hammerhead. Through its rarity, the new species, Sphyrna gilberti, underscores the fragility of shark diversity in the face of relentless human predation.


Quattro, a biology professor in USC's College of Arts and Sciences, didn't set out to discover a new cryptic species, let alone one found exclusively in saltwater. When he started as an assistant professor at USC in 1995, he was largely focused on fish in the freshwater rivers that flow through the state before emptying into the western Atlantic Ocean.


He has wide interests that include conservation, genetic diversity and taxonomy. A driving force in his scientific curiosity is a desire to better understand evolution. As it turns out, South Carolina's four major river basins the Pee Dee, the Santee, the Edisto and the Savannah are a source of particularly rich ore for mining insight into evolutionary history.

Glacial influence had limits


Quattro grew up in Maryland, earned a doctorate at Rutgers University in New Jersey, and completed a post-doc at Stanford University. "New Jersey and Maryland, in particular, had huge glacial influences," said Quattro. "The areas where rivers now flow were covered with glaciers until 10,000 to 15,000 years ago, and as the glaciers receded the taxa followed them upstream."


In contrast, rivers south of Virginia were not covered with glaciers. "In other words, these rivers have been around for quite some time," Quattro said. "The Pee Dee and the Santee are two of the largest river systems on the East coast. And we just got curious how distinct are these rivers from one another?"


Beginning with the pygmy sunfish, Quattro and colleagues examined the genetic makeup of fish species within the ancient freshwater drainage systems. They found the banded pygmy sunfish in all the South Carolina rivers in fact, this widespread species is found in nearly all the river systems of the U.S. southeastern and Gulf coasts, starting from the plains of North Carolina, around Florida, and all the way to and up the Mississippi River.


But two species are much rarer. The bluebarred pygmy sunfish is found only in the Savannah and Edisto systems. The Carolina pygmy sunfish is found only in the Santee and Pee Dee systems. Both species coexist with the common banded pygmy sunfish in these river systems, but are found nowhere else in the world.


From an evolutionary standpoint, it's a noteworthy finding. These rare species are related to the widespread species, yet the details of the inter-relationships such as which predates the others and is thus an ancestral species still defy ready description. The fact that a rare and a common species are located together in an ancient river system is important information in the ongoing struggle to clearly define evolutionary history. In the past, scientists drew taxonomic charts almost solely on the basis of physical structure (morphology) and available fossils. The genetic data revolution of recent decades is helping redefine biology in a much more precise manner, but the process is still in the early going.

From the river to the sea


Quattro has been doing his part by slowly moving down the river systems to the ocean, collecting genetic data the whole way down. In the freshwater rivers, he has examined pygmy sunfishes, other sunfishes and basses. Closer to the sea, he has looked at short-nosed sturgeon, which spend most of their time in the estuary (where the river meets the ocean), but do venture up the river to spawn. And further downriver still, he has looked at shark pups.


South Carolina is a well-known pupping ground for several species of sharks, including the hammerhead. The female hammerhead will birth her young at the ocean-side fringes of the estuary; the pups remain there for a year or so, growing, before moving out to the ocean to complete their life cycle.


In the process of looking at hammerheads, Quattro, his student William Driggers III and their colleagues quickly uncovered an anomaly. The scalloped hammerheads (Sphyrna lewini) that they were collecting had two different genetic signatures, in both the mitochondrial and nuclear genomes. Searching the literature, they found that Carter Gilbert, the renowned curator of the Florida Museum of Natural History from 1961 to 1998, had described an anomalous scalloped hammerhead in 1967 that had 10 fewer vertebrae than S. lewini. It had been caught near Charleston and, because the sample was in the National Museum of Natural History, the team was able to examine it morphologically and suggest that it constituted a cryptic species that is, one that is physically nearly indistinguishable from the more common species.


After publishing the preliminary genetic evidence for the new, cryptic species in the journal Marine Biology in 2006, Quattro and colleagues followed up by making thorough measurements (of 54 cryptic individuals and 24 S. lewini) to fully describe in Zootaxa the new species, S. gilberti, named in Gilbert's honor. The difference in vertebrae, 10 fewer in the cryptic species, is the defining morphological difference.


Apart from the satisfaction of discovery, Quattro has established locations and genetic signatures for a number of closely related, yet distinct, species in South Carolina's rivers, estuaries and coastal waters. The results will go a long way in furthering efforts to accurately define taxonomy and evolutionary history for aquatic life.


His team's work also demonstrates the rarity of the new species. "Outside of South Carolina, we've only seen five tissue samples of the cryptic species," Quattro said. "And that's out of three or four hundred specimens."


Shark populations have greatly diminished over the past few decades. "The biomass of scalloped hammerheads off the coast of the eastern U.S. is less than 10 percent of what it was historically," Quattro said. "Here, we're showing that the scalloped hammerheads are actually two things. Since the cryptic species is much rarer than the lewini, God only knows what its population levels have dropped to."

Shark populations have greatly diminished over the past few decades. "The biomass of scalloped hammerheads off the coast of the eastern U.S. is less than 10 percent of what it was historically," Quattro said. "Here, we're showing that the scalloped hammerheads are actually two things. Since the cryptic species is much rarer than the lewini, God only knows what its population levels have dropped to."

New SD card format is speedy enough for 4K video

Outside of a few smartphones, 4K video capture has largely been limited to pro-level hardware; the SD cards in regular cameras frequently can't handle so many pixels at once. That won't be a problem in the near future, as the SD Association has just unveiled an Ultra High Speed Class 3 (U3) card ...

New Institute will focus on training, research and the latest safety information



The University of Houston will be part of a Texas-based operation established by the Bureau of Safety and Environmental Enforcement to manage the Ocean Energy Safety Institute, according to an announcement Thursday.

The five-year, $5 million agreement will be managed by the Texas A&M Engineering Experiment Station's Mary Kay O'Connor Process Safety Center, working with UH, Texas A&M University and the University of Texas at Austin.

Ramanan Krishnamoorti, chief energy officer for the University of Houston, said the goal will be to provide both industry and regulators with reliable knowledge about critical safety issues.

"Safety is going to have to be integrated into rapidly evolving technology to support ultra-deep exploration and production," he said. "Regulators have to be kept in the loop. We can bring the best academic minds to work with industry and government regulators to implement the best available and safest technology in deep water and extreme environments."

The announcement was made today in College Station, where representatives of the bureau gathered with those from the three universities.

"I look forward to working closely with our partners at the Institute on finding ways to improve safety offshore," said Brian Salerno, director of the Bureau of Safety and Environmental Enforcement (BSEE). "The Institute will develop a program of research, technical assistance and education that serves as a center of expertise in offshore oil and gas exploration, development and production technology, including frontier areas, such as high temperature/high pressure reservoirs, deep water and Arctic exploration and development."

The Institute stems from a recommendation from the Ocean Energy Safety Advisory Committee, a federal advisory group comprised of representatives from industry, federal government agencies, non-governmental organizations and the academic community.

It won't have regulatory authority over the offshore industry but is intended to be a source of unbiased, independent information.
M. Sam Mannan, chemical engineering professor at Texas A&M and principal investigator for the project, said each of the three universities involved bring something to the institute.

"We applaud BSEE for supporting this major undertaking of national importance that will impact ocean energy safety for the nation and world for years to come," he said.

Krishnamoorti, who heads the UH energy initiative and is a co-principal investigator for the Institute, said the University of Houston's strengths include its proximity to, and relationship with, companies engaged in the offshore industry, many of whom are based in Houston, as well as several of its academic programs.

UH has the nation's only subsea engineering program, and Krishnamoorti said the University's geosciences and seismic programs also will be an advantage for the new Institute, as will its imaging center, the National Center for Airborne Laser Mapping, which could provide continuous monitoring for leaks or spills.

The Institute, which was first proposed after the 2010 Deepwater Horizon oil spill, will provide recommendations and technical assistance to BSEE related to emerging technologies and the best available and safest technologies. In addition, it will develop and maintain an equipment failure monitoring system and train federal employees to enable them to remain current on state-of-the-art technology.

The Institute will also promote collaboration among federal agencies, industry, standards organizations, academia and the National Academy of Sciences. Information on issues related to offshore research and best practices will be shared with industry, government and the public through Institute-held forums.
