Obama makes impassioned plea for gun control legislation

By Steve Holland

WASHINGTON (Reuters) - President Barack Obama attempted on Thursday to inject fresh momentum into efforts to pass gun-control legislation, pleading with U.S. lawmakers not to forget those shot to death in Newtown, Connecticut three months ago.

Amid signs that he may have to accept a scaled-down version of gun legislation, Obama sounded a note of frustration in calling upon Americans to demand action from the U.S. Congress in the weeks ahead.

He said the legislation's opponents, the powerful U.S. gun lobby led by the National Rifle Association, are "doing everything they can" to derail the effort barely 100 days after the Sandy Hook Elementary School massacre, in which a gunman killed 20 children, six staff members and then himself.

"The entire country pledged we would do something about it and that this time would be different. Shame on us if we've forgotten. I haven't forgotten those kids. Shame on us if we've forgotten," said Obama, appearing at the White House with mothers of children who had been shot to death.

The gunman in Newtown, Adam Lanza, fired 154 rounds in less than 5 minutes, selecting high capacity magazines from a home arsenal stocked with swords, knives and a cache of guns, officials said Thursday.

Despite events like this, a grassroots organizing effort by Obama supporters and a high-profile advertising campaign funded by New York Mayor Michael Bloomberg to keep up the pressure, gun legislation has been stalled on Capitol Hill in recent weeks.

The best chance of success for gun-control advocates is that Congress will approve universal background checks for gun purchasers and tougher penalties for gun trafficking.

Less likely to pass are bans on assault weapons and high-capacity ammunition clips, two of the main proposals to emerge from Vice President Joe Biden's gun violence task force, formed by Obama after the Newtown shootings.

'JUST THE BEGINNING'

Biden seemed to acknowledged the challenge when he said on a conference call on Wednesday organized by Mayors Against Illegal Guns that the administration will keep pressing for action regardless of what Congress does in the immediate future.

"Let me say this as clearly as I can: This is just the beginning," Biden said.

Obama had hoped at the outset of his second term to use his re-election mandate to make rapid progress on three major issues: gun violence, deficit-reduction and immigration reform.

All are moving slowly, however.

Immigration may offer the best prospect for action as Republicans seek to attract more Hispanic Americans who voted overwhelming for Obama and his Democrats in the 2012 elections.

Republicans insist that any pathway to citizenship for 11 million illegal immigrants be preceded by certification that U.S. borders are secure.

The biggest stumbling block to an immigration bill concerns creation of a guest-worker program to allow immigrants to cross the U.S.-Mexican border legally for temporary jobs.

U.S. labor unions, which worry such a program would lead to a loss of jobs for Americans, and the U.S. Chamber of Commerce have yet to arrive at a formula acceptable to both. Their agreement is considered crucial to bringing Congress along.

Obama has said he is encouraged by the progress, and he believes the dispute over the guest-worker program can be resolved. After first declaring the U.S.-Mexican border sufficiently secure, Obama now says it can be improved, a position that may permit him to make a deal with Republicans.

"I'm actually optimistic about this, in part because I think both Republicans as well as Democrats are now recognizing that it's the right thing to do," Obama told Univision, a Spanish-language network, in an interview on Wednesday.

Obama's attempt to negotiate a "grand bargain" aimed at reducing the U.S. budget deficit is facing old-fashioned political gridlock and could collapse into a partisan sinkhole.

In a fresh round of schmoozing to discuss this and other legislative items, Obama will dine with a dozen Republican senators on April 10, the second such meeting he will have held in his attempts to engage his political opponents.

TAXING THE RICH

Lawmakers are still bruised from a fight over $85 billion in automatic spending cuts that went into effect a month ago despite Obama's attempt to head them off.

Obama still wants what Republicans refused to give him in that budget fight, an increase in taxes on the wealthy by eliminating some deductions and loopholes. Republicans instead want to cut spending.

The White House struck a pessimistic note this week on the prospects for success given the Republican leadership's refusal to agree to raise more tax revenues.

"As long as Republicans are saying we're not going to ask the wealthiest and well-connected to pay a single dime to reduce our deficit, then it is hard to imagine that we're going to reach a compromise," White House deputy press secretary Josh Earnest said Wednesday.

The difficulties in gaining passage of major legislation reflects the continued grip partisan politics holds on Washington, with the White House and Senate run by Democrats and the House of Representatives controlled by Republicans. This makes the 2014 midterm congressional elections of increasing importance.

"Look, it's what we all thought when Obama was re-elected," said Larry Sabato, director of the University of Virginia's Center for Politics. "There is just not going to be a lot of new legislation in Obama's second term, unless he wins the House in 2014, and even then it looks very, very tough."

Mountain pine beetle genome decoded

Mar. 26, 2013 ? The genome of the mountain pine beetle -- the insect that has devastated B.C.'s lodgepole pine forests -- has been decoded by researchers at the University of British Columbia and Canada's Michael Smith Genome Sciences Centre.

This is a first for the mountain pine beetle and only the second beetle genome ever sequenced. The first was the red flour beetle, a pest of stored grains. The genome is described in a study published Tuesday in the journal Genome Biology.

"We know a lot about what the beetles do," says Christopher Keeling, a research associate in Prof. Joerg Bohlmann's lab at the Michael Smith Laboratories. "But without the genome, we don't know exactly how they do it."

"Sequencing the mountain pine beetle genome provides new information that can be used to help manage the epidemic in the future."

The genome revealed large variation among individuals of the species -- about four times greater than the variation among humans.

"As the beetles' range expands and as they head into jack pine forests where the defensive compounds may be different, this variation could allow them to be more successful in new environments," says Keeling.

Researchers isolated genes that help detoxify defence compounds found under the bark of the tree -- where the beetles live. They also found genes that degrade plant cell walls, which allow the beetles to get nutrients from the tree.

Keeling, Bohlmann and their colleagues also uncovered a bacterial gene that has jumped into the mountain pine beetle genome. This gene codes for an enzyme that digests sugars.

"It might be used to digest woody tissue and/or the microorganisms that grow in the beetle's tunnels underneath the bark of the tree," said Keeling. "Gene transfers sometimes make organisms more successful in their environments."

This study involved researchers from the University of Northern British Columbia and the University of Alberta.

Characteristics of the mountain pine beetle genome

  • 12 pairs of chromosomes
  • Approximately 13,000 genes
  • The mountain pine beetle separated from the red flour beetle -- the only other beetle genome sequenced to date -- about 230 million years ago. According to Keeling, "the two insects have about the same relatedness as a pine tree and a head of lettuce."
  • The mountain pine beetle is closely related to other significant pests in North American forests such as the southern pine beetle, Douglas-fir beetle, eastern larch beetle, and spruce beetle. Insights gained from sequencing the mountain pine beetle genome can be transferred to these beetles, and other forest insect pests around the world.

Mountain pine beetle epidemic

The mountain pine beetle has infested over 18 million hectares of lodgepole pine in British Columbia -- an area more than five times larger than Vancouver Island -- causing enormous damage to the environment and forest industry. In recent years, the insect has moved further north and east, over the Canadian Rockies, and is now approaching the Alberta-Saskatchewan border. It is also beginning to infest other pine trees -- jack pine, a jack-lodgepole hybrid, limber pine, and the endangered whitebark pine. Jack pine boreal forests extend from Alberta to the Atlantic provinces. The mountain pine beetle also lives in Colorado, Wyoming, Arizona and South Dakota.

Clean electricity from bacteria? Researchers make breakthrough in race to create 'bio-batteries'

Mar. 25, 2013 ? Scientists at the University of East Anglia have made an important breakthrough in the quest to generate clean electricity from bacteria.

Findings published today in the journal Proceedings of the National Academy of Sciences (PNAS) show that proteins on the surface of bacteria can produce an electric current by simply touching a mineral surface.

The research shows that it is possible for bacteria to lie directly on the surface of a metal or mineral and transfer electrical charge through their cell membranes. This means that it is possible to 'tether' bacteria directly to electrodes -- bringing scientists a step closer to creating efficient microbial fuel cells or 'bio-batteries'.

The team collaborated with researchers at Pacific Northwest National Laboratory in Washington State in the US.?

Shewanella oneidensis is part of a family of marine bacteria. The research team created a synthetic version of this bacteria using just the proteins thought to shuttle the electrons from the inside of the microbe to the rock.

They inserted these proteins into the lipid layers of vesicles, which are small capsules of lipid membranes such as the ones that make up a bacterial membrane. Then they tested how well electrons travelled between an electron donor on the inside and an iron-bearing mineral on the outside.

Lead researcher Dr Tom Clarke from UEA's school of Biological Sciences said: "We knew that bacteria can transfer electricity into metals and minerals, and that the interaction depends on special proteins on the surface of the bacteria. But it was not been clear whether these proteins do this directly or indirectly though an unknown mediator in the environment.

"Our research shows that these proteins can directly 'touch' the mineral surface and produce an electric current, meaning that is possible for the bacteria to lie on the surface of a metal or mineral and conduct electricity through their cell membranes.

"This is the first time that we have been able to actually look at how the components of a bacterial cell membrane are able to interact with different substances, and understand how differences in metal and mineral interactions can occur on the surface of a cell.

"These bacteria show great potential as microbial fuel cells, where electricity can be generated from the breakdown of domestic or agricultural waste products.

"Another possibility is to use these bacteria as miniature factories on the surface of an electrode, where chemicals reactions take place inside the cell using electrical power supplied by the electrode through these proteins."

Biochemist Liang Shi of Pacific Northwest National Laboratory said: "We developed a unique system so we could mimic electron transfer like it happens in cells. The electron transfer rate we measured was unbelievably fast -- it was fast enough to support bacterial respiration."

The finding is also important for understanding how carbon works its way through the atmosphere, land and oceans.

"When organic matter is involved in reducing iron, it releases carbon dioxide and water. And when iron is used as an energy source, bacteria incorporate carbon dioxide into food. If we understand electron transfer, we can learn how bacteria controls the carbon cycle," said Shi.

The project was funded by the Biotechnology and Biological Sciences Research Council (BBSRC) and the US Department of Energy.

Study: Health overhaul to raise claims cost 32 pct

WASHINGTON (AP) ? Insurance companies will have to pay out an average of 32 percent more for medical claims on individual health policies under President Barack Obama's overhaul, the nation's leading group of financial risk analysts has estimated.

That's likely to increase premiums for at least some Americans buying individual plans.

The report by the Society of Actuaries could turn into a big headache for the Obama administration at a time when many parts of the country remain skeptical about the Affordable Care Act.

While some states will see medical claims costs per person decline, the report concluded the overwhelming majority will see double-digit increases in their individual health insurance markets, where people purchase coverage directly from insurers.

The disparities are striking. By 2017, the estimated increase would be 62 percent for California, about 80 percent for Ohio, more than 20 percent for Florida and 67 percent for Maryland. Much of the reason for the higher claims costs is that sicker people are expected to join the pool, the report said.

The report did not make similar estimates for employer plans, the mainstay for workers and their families. That's because the primary impact of Obama's law is on people who don't have coverage through their jobs.

The administration questions the design of the study, saying it focused only on one piece of the puzzle and ignored cost relief strategies in the law such as tax credits to help people afford premiums and special payments to insurers who attract an outsize share of the sick. The study also doesn't take into account the potential price-cutting effect of competition in new state insurance markets that will go live on Oct. 1, administration officials said.

At a White House briefing on Tuesday, Health and Human Services Secretary Kathleen Sebelius said some of what passes for health insurance today is so skimpy it can't be compared to the comprehensive coverage available under the law. "Some of these folks have very high catastrophic plans that don't pay for anything unless you get hit by a bus," she said. "They're really mortgage protection, not health insurance."

A prominent national expert, recently retired Medicare chief actuary Rick Foster, said the report does "a credible job" of estimating potential enrollment and costs under the law, "without trying to tilt the answers in any particular direction."

"Having said that," Foster added, "actuaries tend to be financially conservative, so the various assumptions might be more inclined to consider what might go wrong than to anticipate that everything will work beautifully." Actuaries use statistics and economic theory to make long-range cost projections for insurance and pension programs sponsored by businesses and government. The society is headquartered near Chicago.

Kristi Bohn, an actuary who worked on the study, acknowledged it did not attempt to estimate the effect of subsidies, insurer competition and other factors that could mitigate cost increases. She said the goal was to look at the underlying cost of medical care.

"Claims cost is the most important driver of health care premiums," she said.

"We don't see ourselves as a political organization," Bohn added. "We are trying to figure out what the situation at hand is."

On the plus side, the report found the law will cover more than 32 million currently uninsured Americans when fully phased in. And some states ? including New York and Massachusetts ? will see double-digit declines in costs for claims in the individual market.

Uncertainty over costs has been a major issue since the law passed three years ago, and remains so just months before a big push to cover the uninsured gets rolling Oct. 1. Middle-class households will be able to purchase subsidized private insurance in new marketplaces, while low-income people will be steered to Medicaid and other safety net programs. States are free to accept or reject a Medicaid expansion also offered under the law.

Obama has promised that the new law will bring costs down. That seems a stretch now. While the nation has been enjoying a lull in health care inflation the past few years, even some former administration advisers say a new round of cost-curbing legislation will be needed.

Bohn said the study overall presents a mixed picture.

Millions of now-uninsured people will be covered as the market for directly purchased insurance more than doubles with the help of government subsidies. The study found that market will grow to more than 25 million people. But costs will rise because spending on sicker people and other high-cost groups will overwhelm an influx of younger, healthier people into the program.

Some of the higher-cost cases will come from existing state high-risk insurance pools. Those people will now be able to get coverage in the individual insurance market, since insurance companies will no longer be able to turn them down. Other people will end up buying their own plans because their employers cancel coverage. While some of these individuals might save money for themselves, they will end up raising costs for others.

Part the reason for the wide disparities in the study is that states have different populations and insurance rules. In the relatively small number of states where insurers were already restricted from charging higher rates to older, sicker people, the cost impact is less.

"States are starting from different starting points, and they are all getting closer to one another," said Bohn.

The study also did not model the likely patchwork results from some states accepting the law's Medicaid expansion while others reject it. It presented estimates for two hypothetical scenarios in which all states either accept or reject the expansion.

Larry Levitt, an insurance expert with the nonpartisan Kaiser Family Foundation, reviewed the report and said the actuaries need to answer more questions.

"I'd generally characterize it as providing useful background information, but I don't think it's complete enough to be treated as a projection," Levitt said. The conclusion that employers with sicker workers would drop coverage is "speculative," he said.

Another caveat: The Society of Actuaries contracted Optum, a subsidiary of UnitedHealth Group, to do the number-crunching that drives the report. United also owns the nation's largest health insurance company. Bohn said the study reflects the professional conclusions of the society, not Optum or its parent company.
