Romney hammers Obama’s Health Care: Calls for Repeal

Posted on by

First Republican Presidential candidate to vow reversal

From National Review:

It is an historic usurpation of the legislative process — he unleashed the nuclear option, enlisted not a single Republican vote in either chamber, bribed reluctant members of his own party, paid-off his union backers, scapegoated insurers, and justified his act with patently fraudulent accounting.

His health-care bill is unhealthy for America. It raises taxes, slashes the more private side of Medicare, installs price controls, and puts a new federal bureaucracy in charge of health care. It will create a new entitlement even as the ones we already have are bankrupt. For these reasons and more, the act should be repealed. That campaign begins today.

McCain: We’re going to repeal this Sucker

Posted on by

Mainstream Republican gets Tea Party fever

Known as a cautious old guard Republican, Senator John McCain let it rip on George Stephanopolous yesterday morning. Stephanopoulous was taken aback by the old fighter pilot's dogged determination.

From ABC News GMA via Breitbart:

It's a massive government takeover of the health care system of America... With all this euphoria inside the Beltway, all this champagne popping, outside the Beltway the American people don't like it. And we're going to try to repeal it. There will be a very spirited campaign coming up between now and November. And there will be a very heavy price to pay for it.

And in another interview McCain promised to give a big middle finger to the Dems. From The Hill:

"There will be no cooperation for the rest of the year," McCain said during an interview Monday on an Arizona radio affiliate. "They have poisoned the well in what they've done and how they've done it."

Just 5 Questions: Fingerprinting the Climate

Posted on by
NASA's DC-8 sits on the runway at Dryden's Aircraft Operations Facility in Palmdale, Calif., prior to the Operation IceBridge test flight on March 17, 2010NASA's Operation IceBridge mission, the largest airborne survey ever flown of Earth's polar ice, kicks off its second year of study when NASA aircraft arrive in Greenland March 22.

The IceBridge mission allows scientists to track changes in the extent and thickness of polar ice, which is important for understanding ice dynamics. IceBridge began in March 2009 as a means to fill the gap in polar observations between the loss of NASA's Ice, Cloud and land Elevation Satellite, or ICESat, and the launch of ICESat-2, planned for 2015. Annual missions fly over the Arctic in March and April and over Antarctica in October and November.

"NASA's IceBridge mission is characterizing the changes occurring in the world's polar ice sheets," said Tom Wagner, cryosphere program manager at NASA Headquarters in Washington. "The mission's goal is to collect the most important data for improving predictive models of sea level rise and global climate change."

NASA research pilots Dick Ewers (center) and Bill Brockett (right) of Dryden Flight Research Center, Edwards, CalifResearchers plan to resurvey previous flight lines and former ground tracks of ICESat while adding new areas of interest. Scientists also will target some areas that have been undergoing mysterious changes. The major glaciers in southeast Greenland once thinned simultaneously, but some of those glaciers have been thinning at an accelerated rate -- as much as 40 feet per year -- while others have thickened. And glaciers in northwest Greenland, once a stable region, have mostly begun to thin.

In preparation for approximately 200 science flight hours during the spring 2010 campaign, engineers have been outfitting NASA's DC-8 aircraft with an array of science instruments. On March 21-22, the aircraft will travel to Thule, Greenland, where researchers and crew will spend about five weeks making 10 to 12 science flights. The first priority is to survey Arctic sea ice, which reaches its maximum extent each year in March or early April. High- and low-altitude flights also will survey Greenland's ice sheet and outlet glaciers.

In mid-April, the engineers will transfer the science instruments to the smaller, more maneuverable P-3B aircraft. The crew will spend May making another 10 to 12 science flights from Kangerlussuaq and Thule, Greenland.

Both aircraft will carry the Airborne Topographic Mapper, or ATM -- a laser altimeter similar to those on ICESat. ATM measures changes in the surface elevation of the ice by reflecting lasers from the ground back to the aircraft and converting the readings into elevation maps. Another laser altimeter, the Land, Vegetation, and Ice Sensor, operates at higher altitudes and can survey larger areas quickly.

NASA's Operation IceBridge mission will make science flights from Kangerlussuaq and Thule, Greenland, in spring 2010 to survey the area's ice sheet, outlet glaciers and sea iceThe spring flights are led by project scientists Lora Koenig of NASA's Goddard Space Flight Center in Greenbelt, Md., and Michael Studinger of Goddard Earth Science and Technology Center at the University of Maryland. The mission also includes scientists, crew and technicians from Goddard, Wallops, NASA's Dryden Flight Research Center in Edwards, Calif., NASA's Ames Research Center in Moffett Field, Calif.; The Earth Institute at Columbia University in Palisades, N.Y.; the University of Kansas; and the University of Washington.

The versatility of the planes will allow some new observations not currently possible from satellites. Radar instruments from the University of Kansas and a gravimeter from Columbia University will allow scientists to "see" snow, ice, and bedrock characteristics at depths below the surface. Such information will enhance our understanding of glacier and ice sheet processes and will help scientists predict a glacier's future behavior.

"NASA has a unique capability to look at these things from a bird's-eye perspective, not only from space but also from multiple long-range, high performance aircraft," said John Sonntag, a senior scientist with URS Corporation in Wallops Island, Va., and member of the IceBridge management team. "If not for IceBridge, the global science community and the public would miss out on a great deal of knowledge about Greenland and Antarctica."

Shuttle Detector at Heart of Volcano Alert System

Posted on by
Tim Griffin works with the mobile leak detector in the back seat of a Costa Rican airplane before a sampling flightAs Tim Griffin and his team were working on better ways to detect hazardous gases on the shuttle launch pad, they found out they also could build something to find hazardous gases venting from a volcano.

That means they may be only a short time away from building an early warning system for volcano eruptions -- a system that could give those near an active cone days or more to evacuate to safety.

"There are all kinds of volcano eruptions, some have all kinds of gases and some don't have any gases," Griffin said. "The long-term idea for this is that we'd be able to characterize the volcanoes. Then if the volcano becomes more active, we can get a better idea of what's going on, how active it is, (and) do we think it's going to be a violent eruption or mainly gases coming out?"

Tim Griffin, foreground, and designer Richard Arkin miniaturized the leak detector system used by the space shuttle and then found out it could be used for volcano studiesGriffin, who is the chief of NASA Kennedy Space Center's Chemical Analysis Branch and holds a Ph.D. in chemistry, never studied volcanoes. Instead, his group's goal was to shrink the leak detection system at the launch pad from the size of three refrigerators to something that could be carried by hand, in a car or perhaps inside a spacecraft.

"This project started off as a way to push the boundaries with our shuttle system," said Richard Arkin of ASRC Aerospace, the detector's co-designer. "We wanted to make it smaller, more powerful and lighter while still maintaining operational abilities and maintenance."

Parts of the miniaturization work were easy, such as going from numerous sampling ports required at the pad to a single port for the smaller machine. Other aspects, such as building smaller pumps and other components, required innovation and invention. In both, a mass spectrometer is used to find out what chemicals are present in the air.

They also set out to make the unit relatively autonomous, but still reliable and hearty.

At this point, the detector weighs in at 75 pounds. It stands about 9 inches tall and its footprint is a bit larger than a backpack. In fact, one of the goals of the project is to make it small enough to be carried in a backpack.

Griffin was talking about some of the work involved in chemical analysis at a conference when officials from Costa Rica's scientific program asked about applying the technology to the volcanic studies. It started to look like a natural fit.

The mobile leak detector was placed inside a small aircraft and flown over the Turrialba volcano to gauge the air around the volcanoCosta Rica proved a good testing ground for the equipment because most of the population lives around or near four active volcanoes. They don't worry only about sudden eruptions, but also high concentrations of carbon dioxide the volcanoes vent. The gas tends to kill all vegetation and livestock near the venting areas, but people can't see the carbon dioxide.

The detector showed a way to find out where the gas pockets are and how they change. The team flew the detector on three different kinds of airplanes, where it modeled the chemicals in volcanic plumes in three dimensions, a level of precision that astonished Arkin.

"That was something that I never thought about doing," Arkin said.

Tim Griffin and his team of researchers carried the leak detector by hand into the cone of the Turrialba volcano in Costa Rica in 2005The team also put the detector in the backseat of a car and drove it through Costa Rican cities to sample the air and also carried it into the volcanoes by hand. In the future, Griffin wants to load it inside drones so the detection system can fly directly into the plumes of erupting mountains without endangering a pilot.

The results are expected to provide more information to help researchers pinpoint what volcanoes are doing at any given time, and when or if they might be about to spew.

Although the highest potential is still a few years away for the detection system, Griffin said he can envision a time when there are a number of detectors based around the world ready to scan volcanoes suspected of erupting. The extra information could be enough to convince officials to order an evacuation before it's too late.

A Sleep Remedy with Proprietary Secrets

Posted on by

A new product, Dream Water, is designed to help one relax, fall asleep and improve the quality of sleep using the all natural ingredients melatonin, GABA and 5-HTP (tryptophan). A single-dose 2.5 oz bottle retails for $2.99. They also offer a more dilute formulation in an 8 oz bottle. They suggest drinking half a bottle, keeping it at your bedside, and drinking more if you wake during the night. What dosage will you get from half a bottle? From a whole bottle? There’s no way to know. They offer a money back guarantee, free shipping, free samples, and lots of testimonials; but they refuse to disclose how much of what is in their product.

The DSHEA only permits structure and function claims like “supports prostate health,” but this product is clearly being promoted as a remedy for insomnia. The “Quack Miranda warning” is not displayed on the home page, but the “Dream Responsibly” page says “These statements have NOT been evaluated by the Food and Drug Administration. This product is NOT intended to diagnose, treat, prevent or cure any disease.”

Is it legal to sell this as a remedy for insomnia? I guess the legality depends on whether you define insomnia as a disease. Maybe they define it as an impairment in a function that needs supporting. Maybe they can get away with it.

What’s the scientific evidence?

It’s a “perfect blend” of three ingredients that they say produce relaxation and sleep. Do these three natural medicines really work for insomnia? I looked up the ingredients in The Natural Medicines Comprehensive Database.

  • Melatonin: For primary insomnia, melatonin reduces the time it takes to fall asleep by 12 minutes but does not improve sleep efficiency. There have been reports of adverse effects like elevated blood pressure and increased bleeding tendency in patients taking Coumadin. There are concerns about possible interactions with 11 categories of drugs, from antidiabetes drugs to contraceptives. The Dream Water website doesn’t mention any of this.
  • Tryptophan is rated as “possibly unsafe” and there is “insufficient reliable evidence to rate” effectiveness for insomnia. There is a long list of possible interactions with several other categories of drugs.
  • GABA – insomnia is not even on the NMCD’s list of things that “people use this for.” They found insufficient reliable information about safety and effectiveness to even give it a rating. We don’t think GABA even crosses the blood-brain barrier.

Inquiring Minds Want to Know

I wrote their representative and asked:

I’m wondering about the dosage. Can you tell me how much melatonin, tryptophan and GABA are in each bottle? Have any placebo-controlled studies been done?

She answered:

Unfortunately we cannot share specifics as the formula is proprietary. We also don’t have any formal placebo testing as of yet.

I replied:

So you’re suggesting that I use something with an unknown amount of active drugs, something that has not been properly tested, and that I simply take your word for it that the company has found a “perfect blend” without knowing how they found it or what exactly they found? No thanks, I’m not that gullible.

She answered:

I completely understand your concerns.

Gee, knowing that she understands makes me feel so much better….

Double Standard?

ConsumerLab tests dietary supplements to assess purity and to determine if they contain the amount of ingredient claimed on the container label. How can they determine whether the amount in the container matches amount listed on the label if there is no amount listed on the label? And if they test Dream Water and measure the amounts of the 3 components, wouldn’t that reveal the proprietary secret?

I wonder about the folks who are selling Dream Water. If they had an infection, would they be willing to take a new pharmaceutical product that was not FDA approved, that was an untested mixture of 3 prescription antibiotics, two of which had not been proven effective for that infection? Would they buy it if the dosage of the ingredients was kept secret, and would they be willing to trust the word of some unidentified person in the pharmaceutical company that it was an optimal mixture (someone who was claiming to somehow know it was optimal without bothering to test it)?

For crying out loud, even my food labels specify how many grams of fat are in a serving!
