Dwarf galaxies provide new insights on dark matter

ScienceDaily (Apr. 2, 2012) ? There's more to the cosmos than meets the eye. About 80 percent of the matter in the universe is invisible to telescopes, yet its gravitational influence is manifest in the orbital speeds of stars around galaxies and in the motions of clusters of galaxies. Yet, despite decades of effort, no one knows what this "dark matter" really is. Many scientists think it's likely that the mystery will be solved with the discovery of new kinds of subatomic particles, types necessarily different from those composing atoms of the ordinary matter all around us. The search to detect and identify these particles is underway in experiments both around the globe and above it.

Scientists working with data from NASA's Fermi Gamma-ray Space Telescope have looked for signals from some of these hypothetical particles by zeroing in on 10 small, faint galaxies that orbit our own. Although no signals have been detected, a novel analysis technique applied to two years of data from the observatory's Large Area Telescope (LAT) has essentially eliminated these particle candidates for the first time.

"In effect, the Fermi LAT analysis compresses the theoretical box where these particles can hide," said Jennifer Siegal-Gaskins, a physicist at the California Institute of Technology in Pasadena, Calif., and a member of the Fermi LAT Collaboration.

WIMPs, or Weakly Interacting Massive Particles, represent a favored class of dark matter candidates. Some WIMPs may mutually annihilate when pairs of them interact, a process expected to produce gamma rays -- the most energetic form of light -- that the LAT is designed to detect.

"One of the best places to look for these faint gamma-ray signals is in dwarf spheroidal galaxies, small satellites of our own Milky Way galaxy that we know possess large amounts of dark matter," Siegal-Gaskins explained. "From an astrophysical perspective, these are downright boring systems, with little gas or star formation and no objects like pulsars or supernova remnants that emit gamma rays."

In addition, many dwarfs lie far away from the plane of our galaxy, which produces a broad band of diffuse gamma-ray emission that stretches all around the sky. Selecting only dwarf galaxies at great distances from this plane helps minimize interference from the Milky Way.

The team examined two years of LAT-detected gamma rays with energies in the range from 200 million to 100 billion electron volts (GeV) from 10 of the roughly two dozen dwarf galaxies known to orbit the Milky Way. Instead of analyzing the results for each galaxy separately, the scientists developed a statistical technique -- they call it a "joint likelihood analysis" -- that evaluates all of the galaxies at once without merging the data together. No gamma-ray signal consistent with the annihilations expected from four different types of commonly considered WIMP particles was found.

For the first time, the results show that WIMP candidates within a specific range of masses and interaction rates cannot be dark matter. A paper detailing these results appeared in the Dec. 9, 2011, issue of Physical Review Letters.

"The fact that we look at 10 dwarf galaxies jointly not only increases the statistics, but it also makes the analysis much less sensitive to fluctuations in the gamma-ray background and to uncertainties in the way the dark matter may be distributed around the dwarfs," said Maja Llena Garde, a graduate student at Stockholm University in Sweden and a co-author of the study.

For any given properties of a dark matter particle, the distribution of the particles has a significant impact on the expected gamma-ray signal, a wrinkle that often is handled inadequately, if at all, in previous studies.

The motions of a dwarf galaxy's stars trace out the profile of the massive dark matter halo in which they're embedded, but these tiny galaxies often have very few stars to track. The result is uncertainty in the way dark matter is distributed along the line of sight to the dwarf, which affects the expected flux of gamma rays detected by the LAT. By addressing uncertainties in the dwarfs' dark matter profiles, the LAT team's results are among the most accurate.

"An important element of this work is that we were able to take the statistical uncertainties from an updated study of the dwarf stellar motions and factor it into the LAT data analysis," said Johann Cohen-Tanugi, a physicist at the Laboratory of the Universe and Particles at the University of Montpellier 2 in France and a member of the research team.

"This treatment constitutes a significant step forward, and we hope that future studies will follow our example," noted co-author Jan Conrad, a physics professor at Stockholm University.

The team is in the process of following up the two-year analysis with new ones that will incorporate additional Fermi observing time, improvements made to the LAT's sensitivity and the inclusion of higher-energy gamma rays. Additionally, sky surveys now ramping up may discover new dwarf galaxies that can be included in future studies.

Other members of the LAT Collaboration presenting APS talks on Fermi's dark matter work include Alex Drlica-Wagner and Elliott Bloom, both from the Kavli Institute for Particle Astrophysics and Cosmology (KIPAC), jointly located at SLAC National Accelerator Laboratory and Stanford University, Calif.

Greta Van Susteren: Am I Wrong About This?

Yes, of course the president wants his signature health care law upheld by the U.S. Supreme Court... but I suspect (suspect, since no honest person can say he knows) that it would help him politically if the statute were to be struck down in its entirety. This November election could be close and enthusiasm really matters in a close election. So how does he rev up the enthusiasm? Right now he has considerable drag e.g., gas prices.

Striking down the statute could really rev up the president's base -- add fuel to their current political mantra fire about a 'war on women.' I can think of the ads now, can't you? The president's enthusiasm level among his supporters has been sagging -- something that happens during a second term campaign -- and he needs something to throw his weight behind to really drive his supporters to the polls. An existing health care law won't do it since it feels a bit like, 'been there, done it.' Striking the law down, on the other hand, could really be used to put political panic in his supporters.

Plus... if the law is stricken by the U.S. Supreme Court, those current less-than-enthusiastic Republican voters, and the independents furious about health care may not find their way to the polls come November if they have achieved what they already wanted -- getting rid of the health care law. They may feel a bit ho-hum about voting since they got what they wanted.

Of course if some giant international or domestic event happens, health care law will become irrelevant as it gets pushed down our collective radar screen. And of course, much could happen between now and November.

What do you think? Am I wrong? (By the way, people I know who spends lots of time thinking about politics say I am wrong about this one... )

The Best Registry Cleaner for Windows XP - Technology

The best registry cleaner for XP

XP might be a few years old, but it is still one of the registry cleaners the most popular in the world. But it also has a major problem in the form of ?registration?. To resolve this problem, you only need a registry cleaner, but what is best for XP?

fact is that all the registry cleaners to more or less the same job ? to clean up part of your system as a ?registration?. The registry is a critical component of XP that has all the settings and options for your computer. All of your emails on your current desktop are stored in the database, making it one of the most important and well-used in your system.

This is good, but why the registry is such a problem is simple ? because it is so important, is constantly with XP 100 files in it every day ?. and, unfortunately, is often confused with XP, many of these files stored in the wrong direction, so they corrupt or damaged. This is a big problem, because it contains files that you can read the ?vital? to Windows very difficult, which makes your computer run more slowly and with many errors. To resolve this problem, we only use a registry cleaning tool ? But with so many Windows XP, it is important that you get the best.

Registry cleaners work by scanning every file in your computer registry and fix any of them are imperfect, he found or damaged. This makes your computer, you can find the files it needs when it needs it, making it run much smoother and faster. However, the register as the ?brains? of the computer, so you can be sure that your registry cleaner does not remove / destroy part of it, that your computers are needed.

This is a very sensitive part of Windows XP, the best registry cleaner to go into an agreement with all the problems in the safest way possible, we must.

There are only a handful of registry cleaners, work well under XP ? it is those who have perfectly by a professional team of developers, the time and resources to ensure that their software is created. We found that registry cleaner is safe and reliable for Windows XP called RegAce. RegAce is a very popular detergent, which has exploded in recent months, thanks to unique features that it is apart from the rest. An advanced scanning engine allows you to quickly find and solve potential problems based backup XP and most comprehensive to protect your computer, even if something goes wrong.

US women seek revenge against Japan

By ERIC TALMADGE

SENDAI, Japan (AP) -It was one of those games - one of those really big games - that just doesn't sit right for U.S. women's football coach Pia Sundhage.

As far as she is concerned, her team played better than Japan in last year's World Cup final. She still thinks they should have won.

Now, she is looking ahead to the Olympics. And again, Japan is on her mind.

"We have something to prove every time we play Japan," Sundhage said Saturday ahead of a matchup between the two rivals at the Kirin Challenge Cup on Japan's home turf.

The exhibition tournament features three of the top four-ranked teams in the world. The U.S. national team is ranked No. 1 just ahead of Germany, while Japan is No. 3. The other team competing for the title, Brazil, is No. 4.

The U.S. women's squad, which plays Japan on Sunday, goes into the match the favorite. They have a solid record against the Japanese - 22-1-4 - but have lost some big ones lately.

In the victory that made them national heroes, the Japanese team came from behind twice and held on to better the U.S. women in a penalty shootout following a 2-2 draw to win the World Cup final in Germany last summer. It was the team's first win over the United States, and came as the country was still coming to grips with the devastating earthquake and tsunami that ravaged the northern coastline of Japan in March last year.

"In the World Cup, I think we played better than Japan," Sundhage said. "I think we were a little bit unlucky."

But in their most recent game, the Japanese also won 1-0 on March 5 to advance to the final of the Algarve Cup in Portugal. The U.S. had to settle for third place, but went out strongly with a 4-0 win over Sweden. Japan lost the final to Germany.

Both teams are now looking ahead to the Olympics, which start in July in London.

"We are ready and well," Sundhage said. "I don't think we are as well connected as we will be for the Olympics. We are building up for that."

Japan's coach, Norio Sasaki, said his team is at it peak, although it will be playing without star midfielder Homare Sawa, the FIFA women's world player of the year.

"This is a really important chance for us to beat the United States and Brazil ahead of the Olympics," he said. "They are both great teams."

Sundhage said her team will be focused on playing an aggressive game and will try to keep possession of the ball so that they do not have to defend as much against the Japanese, who are a highly skilled, technical squad.

"One thing is absolutely clear - they have always been a technical team, and they are a more physical team today," she said.

After Sunday's opener, the U.S. plays Brazil on Tuesday. The final game, Brazil vs. Japan, is on Thursday.

CHICAGO The use of metformin in men with prostate cancer before prostatectomy helped to reduce certain metabolic parameters and slow the growth rate of the cancer, according to the results of a phase II study.

Anthony M. Joshua, M.B.B.S., Ph.D., staff medical oncologist at the Princess Margaret Hospital, University Health Network in Toronto, Ontario, Canada, presented the data at the AACR Annual Meeting 2012, held here March 31 - April 4.

Metformin is the most commonly prescribed medication for diabetes. Prior laboratory research has suggested that metformin may also help to improve prognosis in patients with prostate cancer by slowing the growth of the cancerous cells.

To follow up on the laboratory clues, Joshua and colleagues evaluated 22 men with confirmed prostate cancer who had been assigned up to 500 mg of metformin three times a day prior to undergoing prostatectomy.

"This gave us the ability to compare what the prostate cancer looked like when it was first diagnosed to what it looked like when the prostate cancer was removed from the body," said Joshua. "We were able to directly measure the effect of metformin on the prostate cancer."

Patients were assigned metformin for a median duration of 41 days. During that time, none of the men reported grade 3 adverse events, and all of them underwent prostatectomy with no adverse effect related to use of metformin.

The researchers found that metformin significantly reduced fasting glucose, insulin growth factor-1, body mass index and waist-to-hip ratio.

In addition, "although these are preliminary results, metformin appeared to reduce the growth rate of prostate cancer in a proportion of men," Joshua said. "Also, it appeared to reduce one of the main growth pathways that may have contributed to the overall growth of the tumor."

These results may have implications for men with prostate cancer who also have diabetes or early undiagnosed diabetes and for men with prostate cancer whose tumors have characteristics that make them sensitive to metformin, according to Joshua.

"This research builds on the hypothesis that metformin has a role in prostate cancer," he said. "Exactly what that role will be will depend on the results of the analysis currently being completed by our study team and others worldwide."

Joshua is particularly interested in better defining the precise mechanism of action and the subpopulation of patients with prostate cancer for whom metformin has the potential to improve outcomes.

Title: A phase II study of neoadjuvant metformin in prostatic carcinoma

Author Block: Anthony M. Joshua1, Vanessa Zannella1, Barbara Bowes1, Marianne Koritzinsky2, Joan Sweet1, Andrew Evans1, John Trachtenberg1, Michael Jewett1, Antonio Finelli1, Neil Fleshner1, Michael Pollak3. 1Princess Margaret Hospital, Toronto, Ontario, Canada; 2Ontario Cancer Institute, Toronto, Ontario, Canada; 3Jewish General Hospital, Montreal, Quebec, Canada.

Background: Metformin is an inhibitor of the complex 1 in the respiratory chain, and is widely used in diabetes due to its effect on reducing insulin resistance. It has also been recently described to have effects via AMPK on inhibiting the mTOR kinase. Significant preclinical and epidemiological studies suggest its role in chemoprevention. These actions provide significant rationale to evaluate its utility in prostate cancer. We conducted a phase II single centre study of neoadjuvant metformin in localised prostate cancer.

Methods: Men were required to have histologically confirmed prostate cancer involving at least 20% of at least 1 unfragmented biopsy core. Exclusion criteria included patients who on initial assessment are found to be on treatment with any drug used for the treatment of any form of diabetes, or patients that begin treatment for any form of diabetes during the course of the study. Pts were treated with up to 500mg tid of metformin. The primary objectives were to demonstrate safety and tolerability of neoadjuvant metformin administration in men with prostate cancer and to document changes in phospho-AKT signalling indices.

Results: 24 patients were enrolled with 22 evaluable; median age was 64 yrs (range, 45-70 yrs). Baseline characteristics included median PSA 6 ng/mL (range, 3.22-36.11ng/mL). Median duration of drug treatment was 41 days (range 18-81). No grade 3 adverse events were reported, all patients underwent subsequent radical prostatectomy with adverse effects related to metformin. Significant pre-and post changes were noted in serum IGF1 (p=0.02), fasting glucose (p=0.03), BMI (p

Conclusions: Neoadjuvant metformin is well tolerated prior to radical prostatectomy. Data to date indicates promising effects on metabolic parameters, tissue results will be presented including proliferation indices and signaling pathway assessments.

(AP) ? For years, kopek-pinching Soviets sat down in a cheap restaurant in a former mansion of the nobility for plain meals, unaware of the treasure secreted nearby.

Workers restoring the building this week finally found it, unexpectedly, in a storage space hidden between two floors ? more than 1,000 pieces of jewelry, silver service sets stamped with the name of one of Russia's most prominent noble families, mirrors and brushes in silver frames. Many of them were wrapped in newspapers dated from the early months of 1917, as Russia careened toward the Bolshevik Revolution that ended life as the nobles had known it.

Friday's announcement of the find by the Intarsia company, which is performing the restoration work, excited the news media and sparked arguments over who can claim the valuables. The find is so new that experts haven't had time to inspect the goods and estimate their value.

The treasure tale touches on two of Russia's most renowned and romantic figures: Peter the Great and Alexander Pushkin.

The mansion was purchased in 1875 by Duke Vasily Naryshkin, whose family included Nataliya Naryshkina, the second wife of Czar Alexis and the mother of Peter the Great. The mansion had been put together by connecting two 18-century houses, one of which belonged to Pushkin's African grandfather Abram Gannibal.

After the Bolsheviks nationalized private property, part of the mansion was turned into a stolovaya, a canteen-like restaurant serving utilitarian meals, according to Russian news reports. Following the collapse of the Soviet Union, the building housed apartment, became private apartments, then was purchased by Intarsia to be turned into a conference and cultural center.

Intarsia said it would like to display the treasures for public view in the cultural center once it's completed; for now, they're in custody of the city's committee for historical preservation.

But who has the final claim to them hasn't been resolved.

Sergei Malinkovich, head of a regional Communist organization, told the Rosbalt news agency that his group will apply for ownership of the items on the grounds that the group is the successor to the Communists who nationalized state property.

"The essential thing here is that at the moment of the creation of the hiding-place, the treasure was no longer property of the Naryshkins," he said.

The state news agency, meanwhile, cited Ivan Artsishevsky, chairman of the House of Romanov in Russia, as saying it appears the closest relative to the Naryshkins who occupied the house lives in France, but that it was unclear if this person would seek the valuables.
