To many people, breast cancer screening means a mammogram. But for millions of poor, mostly young women who visit Planned Parenthood, it is usually just a physical exam by the only health professional they may ever see.

Those clinical breast exams are controversial ? government advisers don't endorse them. Yet for some, this simple exam has helped spot breast cancer. And Susan G. Komen for the Cure isn't the only group paying Planned Parenthood to do them ? the government does, too. Komen actually funds relatively few.

Surprises like these are emerging about both groups in the dustup over Komen's decision to bar Planned Parenthood from future grants because of a probe spurred by anti-abortion groups. The decision was reversed on Friday after a huge backlash, with critics saying Komen was hurting the very women it aims to serve.

They are women such as Tina Love, an independent filmmaker in Santa Barbara, Calif., whose sister-in-law is famed breast surgeon Dr. Susan Love. Four years ago, when she was 41, Tina Love went to a Planned Parenthood clinic in Santa Barbara.

"I had a lump and I didn't have health insurance," she explained. The agency sent her for a free mammogram, which led to her cancer being diagnosed and treated.

It's not known exactly how many cancers Planned Parenthood has found. But just last June, Komen said screenings it paid for caught 177 cancers over the last five years.

Some things you may not know about Planned Parenthood:

? Most of its services ? 71 percent ? are for birth control and testing and treatment of sexually transmitted diseases. Abortions made up 3 percent of its services in 2010. Cancer screening accounted for about 15 percent.

? Most of Planned Parenthood's clients are too young for breast cancer screening under most guidelines, although they are prime age for cervical cancer screening. About 80 percent are under 35.

? Planned Parenthood doesn't follow the U.S. Preventive Services Task Force guidelines, which do not endorse clinical breast exams and recommend mammograms only every other year starting at age 50. Instead, Planned Parenthood does a physical breast exam on any woman of any age as part of a regular physical, and refers for mammograms any women 40 and older.

? Komen paid for just 170,000 of the more than 4 million clinical breast exams Planned Parenthood performed nationwide over the last five years, and just 6,400 of Planned Parenthood's 70,000 mammography referrals in that time.

? The government has long paid Planned Parenthood for services related to cancer and sexually transmitted diseases. The group gets federal and state money for breast cancer screening service through a program for poor and uninsured women.

Dr. Vanessa Cullins, a vice president with Planned Parenthood Federation of America, defended its use of clinical breast exams. The exam, in which a doctor feels the breast for lumps, is "a good tool" when followed with mammograms and other tests as needed, she said.

In women who may not see other doctors, "we are encouraging breast self-awareness" so that if a lump is found, they'll seek help, she said.

It worked for Michele Azzaro, 45, of Dallas, who first went to Planned Parenthood when she found a lump back in her 20s. It turned out not to be cancerous, and a mammogram provided through Planned Parenthood ruled out cancer again last year.

Azzaro is unemployed and has no insurance, and has relied on Planned Parenthood for cholesterol tests and pretty much all her medical needs for more than two decades.

"Without having their services, I honestly don't know what I would do," she said. "I'm grateful they've been there for me and millions of other women like me."

Muscle Making and Health and fitness center Tools | Pan Teras

Posted on by jack

Muscle mass constructing happens to be an artwork. Nowadays this artwork is becoming practiced by most of the younger era at the gymnasium. Muscle creating helps folks reach a confident outlook. Each time a person builds muscular tissues, his physique becomes strong and can make him appear sturdy. In past times, muscle progress and system health and fitness had been restricted only to guys, but at this time even females are going to gyms to realize physique health. Using an energetic mind and power, folks can obtain the difficult.

Muscle mass building is not really a chance if people have the mandatory machines. In advance of making muscle groups, persons should assemble facts with regards to the club they choose. They must find out about distinct varieties of devices readily available. People have to judge gyms determined by couple of troubles like convenience, style of facility, health and fitness measures adopted, energy beverages applied, and conditioning equipment offered. In the past dumbbells and barbells have been frequently viewed in gyms. These days, while using modify in technological innovation, fashion in gym equipment has started out strengthening.

Almost all of the equipment suppliers are creating the most up-to-date devices to convince buyers. Devices used in gyms is dependent upon the sort. As an example: If folks want to build muscle tissues of their palms, legs and abdomen they must use multi station machines. Multi station gymnasium tools is classified into 4 groups: five station, eight station, 10 station gym and 12 station health and fitness center. Inside a twelve station, all leg movements are coated and it?s handful of boards that help in creating again muscles.

If people today want to physical exercise in a personalized physical fitness center, they need to use customized gymnasium gear. Personalized fitness center products comprises of treadmills, stepper and rowing. Some treadmills offer you three in one workouts. They?re able to become a rowing machine, a twitter, also being a flat bed treadmill. Within a business health and fitness center, people can come across equipment like a lat pulley, cross about pulley, leg ext curl, t-bar, forty five hack squat, and so on.

You can find exclusive plans constructed particularly for hardcore muscle mass builders. This segment includes of large dumbbells and bearings. Many of these bars are present in 10-100 Kg?s. Based to the club, persons can look for these major weights when they want.

BMW PR stunt backfires with weather disaster

By msnbc.com staff

BMW?apologized after?a PR?strategy to pay for the naming rights to a weather system backfired -- that system turned into the deep freeze that's claimed dozens of lives across Europe.

The goal was to promote BMW's?Mini Cooper brand?by paying Germany's meteorological office 299 euros ($392) to name?a system "Cooper"?-- a practice in place since 2002 to help fund?weather monitoring work in Germany. Unfortunately for BMW, the system it was assigned to?turned out to be a killer.

"Of course we are sorry. It was not intentional, you cannot tell in advance what a weather system will do," a company spokeswoman told The Independent of London.

BMW also has had?plans to later this year?name a low-pressure?system "Minnie" -- no word whether that's still in the works, though.

Board rejects mercy for condemned Ohio arsonist (AP)

COLUMBUS, Ohio ? A death row inmate's theory that a mysterious "man in red" could have started the arson fire that killed his 3-year-old son is "an extraordinary stretch of the imagination," the state parole board ruled Wednesday in unanimously rejecting his plea for mercy.

Michael Webb doesn't dispute the 1990 blaze was arson, but he denies starting it and says investigators using now-discredited methods came to the wrong conclusion about where in the house the flames broke out. He says the correct determination points to someone else as the culprit.

Investigators say Webb set the fire to kill his family, collect the insurance and start a new life with his mistress.

The Webb case is one in a series of cases around the U.S. that represents a new legal frontier: Defense attorneys are using advances in the science of fire investigation to challenge arson convictions, in much the same way they are employing DNA to clear those in prison for murder and rape.

The board called Webb's theory of an alternate suspect who could have entered the house undetected "an extraordinary stretch of the imagination."

"Given the overwhelming evidence of guilt, there is no manifest injustice in this case that would warrant the grant of executive clemency," the board said.

Clermont County prosecutor Don White said Wednesday that he wasn't surprised because he always thought Webb's claim was meritless. A message left with Webb's attorney wasn't immediately returned.

Gov. John Kasich has the final say on clemency for Webb, whose execution is on hold because of an unrelated lawsuit over lethal injection.

Research in recent decades has challenged long-held assumptions about how flames spread and the tell-tale signs they leave.

"Our scientific understandings have improved in recent years, and the effect of that has to be to say, `We've got some innocent people who've been declared guilty based on misunderstandings,'" said John Hall, director of analysis and research for the National Fire Protection Association.

For example, decades ago, it was common for investigators to conclude an accelerant like gasoline was used if a fire burned particularly hot. In fact, the new arson science has found no such correlation, experts say. Another mistaken assumption: A V-shaped pattern on a wall of a burned building is proof of arson. All it shows is where a fire started.

One of the biggest arson cases to come under attack is that of Cameron Todd Willingham, convicted in a 1991 fire in Texas that killed his three daughters. He was executed in 2004. But some experts since then have testified that the blaze was probably accidental.

The primary evidence against Willingham was the testimony of arson investigators for the state fire marshal's office, who said they found pour patterns and puddling on the floor. They said those were signs that someone had poured an accelerant throughout Willingham's home.

But Craig Beyler, chairman of the International Association of Fire Safety Science, wrote in a 2009 report that investigators did not have enough evidence to make an arson finding. He cited findings in the field of fire research that were arrived at since the 1991 blaze or became widely accepted after the original investigation.

For example, tests have found that pour-like patterns on the floor can occur because of radiant heat, even without accelerants, according to Beyler's report. Experiments have also found that melted plastics can create patterns that look like liquid spills, Beyler said.

In Ohio, Webb's chief argument is that a fire investigator wrongly concluded that the 1990 blaze started near a closet or a bathroom where Webb acknowledged he was standing.

In a report submitted on Webb's behalf earlier this month, Gerald Hurst, a chemist and fire investigator in Austin, Texas, said that based on gasoline-spill experiments conducted around the U.S. in the years since the crime, the origin of the fire could have been anywhere on the main floor.

That is important to Webb's case because of statements by one of his teenage daughters that she saw "a man in red" in the house the morning of the fire. Webb's attorneys argue that that person could have been the boyfriend of Webb's other daughter.

Webb's lawyers acknowledge Hurst's findings don't exonerate Webb, but say they raise enough questions to justify a new trial.

Prosecutors dismiss the "man in red" theory, saying the girl's statements varied, that no evidence implicating the boyfriend was found, and that the daughter could have actually seen Webb holding a red gas can. They say Webb is presenting nothing new.

Webb is making "a contention of innocence that is refuted by the hard evidence in the case," Clermont County prosecutors said in their filing with the parole board.

Innocence Projects around the country, which previously concentrated on defendants whose convictions could be challenged through DNA, have taken on a number of deadly arson cases in recent years, including ones in Michigan, Iowa and Pennsylvania.

'Cool' gas may form and strengthen sunspots

ScienceDaily (Jan. 31, 2012) ? Hydrogen molecules may act as a kind of energy sink that strengthens the magnetic grip that causes sunspots, according to scientists from Hawaii and New Mexico using a new infrared instrument on an old telescope.

"We think that molecular hydrogen plays an important role in the formation and evolution of sunspots," said Dr. Sarah Jaeggli, a recent University of Hawaii at Manoa graduate whose doctoral research formed a key element of the new findings. She conducted the research with Drs. Haosheng Lin, also from the University of Hawaii at Manoa, and Han Uitenbroek of the National Solar Observatory in Sunspot, NM. Jaeggli now is a postdoctoral researcher in the solar group at Montana State University. Their work is published in the Feb. 1, 2012, issue of The Astrophysical Journal.

They used the new Facility Infrared Spectropolarimeter (FIRS; Seeing Red, below) at the Dunn Solar Telescope at Sunspot, NM, and the older Horizontal Spectrograph. Although built in 1969, the Dunn now is equipped with advanced adaptive optics that correct for much of atmospheric blurring.

The team analyzed seven active regions on the Sun, one in 2001 and six during December 2010 to December 2011 as Sunspot Cycle 23 faded away. The full sunspot sample has 56 observations of 23 different active regions.

Sunspots appear to come and go in approximate 11-year cycles. They are brighter than an arc-welder's torch, but appear black because the surrounding solar surface is so much brighter. Galileo and his contemporaries discovered sunspots in 1610. George Ellery Hale discovered magnetism in spots in 1908, and scientists soon determined that intense magnetism suppresses the normal convective motions present throughout the solar photosphere and forms "cool" spots.

But the details remain a mystery. Among the clues solar physicists have observed is a direct relationship between the spot's inner temperature and its magnetic field strength. But at very low temperatures, the field strength makes a sharp rise.

"This result is puzzling," Jaeggli and her colleagues wrote. It implies some undiscovered mechanism inside the spot.

One suspect is hydrogen atoms combining into hydrogen molecules (H2). The Sun is about 90 percent hydrogen atoms (plus 10 percent helium and 0.13 percent everything else). Most of the hydrogen is ionized atoms since the average surface temperature is an inferno-like 5780K (9944 deg. F). Yet it is a "cool star" since astronomers can detect heavy-element molecules in the solar spectrum. In 1997 they even found water, as traces of super-heated steam, inside spots.

This suggests that a spot's cool umbra, the "black" shadow at center, might let hydrogen molecules combine in surface layers. As early as 1986 the late Prof. Per E. Maltby and colleagues at the University of Oslo predicted that the gas in the umbra could be as much as 5 percent hydrogen molecules.

Such a shift would cause a major change in sunspot dynamics. A basic law of physics is that gas particles exert the same pressure whether they are atoms or molecules. A hydrogen molecule will provide half the pressure of the two atoms it used to be. And bonds between atoms oscillate and rotate, thus storing energy without raising the temperature. (This is why water absorbs a lot of heat before boiling.)

"The formation of a large fraction of molecules may have important effects on the thermodynamic properties of the solar atmosphere and the physics of sunspots," Jaeggli wrote.

But direct measurement of hydrogen molecules in spots is beyond our grasp for now, so the team measured a stand-in, the hydroxyl radical made of one atom each of hydrogen and oxygen (OH). About 1 percent of the mass of the Sun is oxygen. OH dissociates (breaks into atoms) at a slightly lower temperature than H2, meaning H2 can also form in regions where OH is present. By coincidence, one of its infrared spectral lines is 1565.2nm, almost the same as the 1565nm line of iron, used for measuring magnetism in a spot and one of the lines FIRS is designed to observe. (These are twice the wavelength of the deepest red, 770nm, the human eye can see.)

First using the older HSG in 2001, and then with the more advanced FIRS in 2009-10, the team measured magnetic fields across sunspots, and the OH intensity inside spots. From that, they calculated the H2 concentrations.

"We found evidence that significant quantities of hydrogen molecules form in sunspots that are able to maintain magnetic fields stronger than 2,500 Gauss," Jaeggli said. By comparison, Earth's magnetic field, which turns a compass needle, is about one-half Gauss. The team estimated a hydrogen molecule quantity of a few percent.

Jaeggli said its presence leads to a temporary "runaway" intensification of the magnetic field. Magnetic flux emerges from the interior and suppresses convection at the surface, trapping cool gas that has radiated its energy into space. Molecular hydrogen forms, reducing the volume. This is more transparent than atomic hydrogen, so more energy radiates into space, cooling the gas further. Hot gases around the emerging flux compress the cooler region and intensify the magnetic field.

Eventually it levels out, partly from energy radiating in from the surrounding gas. Otherwise, the spot would grow without bounds. As the magnetic field weakens, the H2 and OH molecules heat up and dissociate back to atoms, compressing the remaining cool regions and keeping the spot from collapsing.

The team says that simulations are needed to test their observations. They also note that most of the active regions observed are of modest field strength. They expect that Cycle 24, which is now ramping up, will provide stronger active regions for a test of their hypothesis.

NSO's mission is to advance knowledge of the Sun, both as an astronomical object and as the dominant external influence on Earth, by providing forefront observational opportunities to the research community. NSO is operated by Association of Universities for Research in Astronomy (AURA Inc.) under a cooperative agreement with the National Science Foundation (NSF) for the benefit of the astronomical community.

Founded in 1967, the Institute for Astronomy at the University of Hawaii at Manoa conducts research into galaxies, cosmology, stars, planets, and the Sun. Its faculty and staff are also involved in astronomy education, deep space missions, and in the development and management of the observatories on Haleakala and Mauna Kea.

Seeing Red

The Facility Infrared Spectropolarimeter (FIRS) at the National Solar Observatory's Dunn Solar Telescope is an advanced imaging spectropolarimeter developed by Haosheng Lin and colleagues at the Institute for Astronomy, University of Hawaii at Manoa, and NSO.

FIRS provides simultaneous spectral coverage at visible and infrared wavelengths through the use of a unique dual-armed spectrograph. The geometry of the spectrograph has been specially designed to capture 630.2nm and 1564.8nm lines of hot, neutral iron (Fe I) with maximum efficiency. It can be re-tuned so the infrared arm instead captures light from helium or silicon around 1083nm or, for this study, OH at 1565nm.

In addition, the spectrograph operates in a multiple slit mode. By using narrowband filters, the spectra from four consecutive slit positions can be imaged at once on the same detector. This feature decreases fourfold the time necessary to scan across a large area on the sun, making it an ideal instrument for the study of quickly developing active regions as illustrated in this "data cube" movie. It also operates simultaneously with other instruments at the Dunn, making for powerful observational capabilities.
