Health supplements are essential to strengthen a woman's immune system & fill in the nutritional gaps that are not met by regular food consumption. Special care must be given to varied health issues that are more prevalent in women.
Luckily, there are now health supplements available aimed specifically for women. Most of these health supplements are packed with vitamins & minerals that help boost women health as well as fortify her body's immune system. For example, health supplements with amino acids & antioxidant vitamins (A, C, E) are good for preventing cancer.
Calcium & magnesium are effective in reducing the symptoms of premenstrual syndrome. Vitamin E is crucial in keeping the skin healthy & vibrant as well as improving the body's defense system. Calcium & vitamin D are critical in preventing the attack of osteoporosis. Folic acid is a good supplement that pregnant women could take to prevent defects in the baby's neurological system. Needless to say, there's a large variety of supplements that meet the needs of women health .
Most of these are promptly available in drugstores as well as in specialty health supplement stores. Still, it's important to note that these supplements can't take the place of good diet, regular exercise & a healthy lifestyle. Nevertheless, these health supplements are critical in offering the necessary vitamins & minerals that women need.

NEW YORK (AP) ? Diet Pepsi is tweaking its formula to stay sweet a little longer.
PepsiCo Inc. is testing new artificial sweeteners that let the soda keep its taste for a longer period of time. The problem is that the current sweetener used in the soda ? aspartame ? loses its potency faster than high fructose corn syrup, the sweetener that's used in most regular sodas.
A person with knowledge of the situation says the company had considered importing versions of Diet Pepsi sold in other countries to the U.S. But now it's testing other sweetener mixes, with a new version set to come out as soon as next year.
The new version will use the same formula that creates Diet Pepsi's overall taste, according to the person, who requested anonymity because she wasn't authorized to speak publicly. But it will use a mix of artificial sweeteners, including acesulfame-potassium, or ace-K, that has a longer shelf life.
Aspartame on its own is more sensitive to heat, which is a problem when sodas are sitting in trucks or waiting to be shipped to retailers.
In an e-mailed statement, PepsiCo said that it's "always looking at ways to provide the best consumer experience," but that it has no plans to change the taste formula of Diet Pepsi.
It's not the first time PepsiCo is tweaking a diet soft drink. The company, based in Purchase, N.Y., made a similar switch to its Diet Mountain Dew in 2006. The Coca-Cola Co. tweaked the sweetener used Diet Sprite in 2000.
By blending artificial sweeteners, companies create a "synergistic effect" that prolongs the sweetener's potency, said John Sicher, publisher of the industry tracker Beverage Digest.
PepsiCo's latest tinkering comes as an increasing number of diet drinks have come on the market. Coca-Cola in 2005 introduced its Coke Zero, which is intended to taste more like the original Coke. Pepsi followed up two years alter with Pepsi Max. But Pepsi Max hasn't performed as strongly as Coke Zero.
After losing market share to Coke in recent years, PepsiCo is looking to bolster its flagship soda brand this year. The company is significantly boosting advertising for Pepsi, which two years ago was edged out by Diet Coke as the No. 2 soda in the country. Coke remains No. 1.
Diet Pepsi ranks as No. 7, according to Beverage Digest, and its sales volume last year was about half that of Diet Coke,.
A spokesman for Coca-Cola, Scott Williamson, said there are no changes planned for Diet Coke, which still uses only aspartame as a sweetener.
The U.S. Food and Drug Administration approved ace-K for use in 1998. It is often used in combination with other artificial sweeteners, according to the Center for Science in the Public Interest, a food safety advocacy group. The sweetener is used in a wide range of foods, including baked goods, chewing gum and gelatin desserts, as well as diet soft drinks.

ScienceDaily (Aug. 29, 2012) ? A new study by researchers at UT Dallas' Center for Vital Longevity, Duke University, and the University of Michigan has found that the strength of communication between the left and right hemispheres of the brain predicts performance on basic arithmetic problems. The findings shed light on the neural basis of human math abilities and suggest a possible route to aiding those who suffer from dyscalculia-- an inability to understand and manipulate numbers.
It has been known for some time that the parietal cortex, the top/middle region of the brain, plays a central role in so-called numerical cognition--our ability to process numerical information. Previous brain imaging studies have shown that the right parietal region is primarily involved in basic quantity processing (like gauging relative amounts of fruit in baskets), while the left parietal region is involved in more precise numerical operations like addition and subtraction. What has not been known is whether the two hemispheres can work together to improve math performance. The new study demonstrates that they can. The findings were recently published online in Cerebral Cortex.
In the study, conducted in Dallas and led by Dr. Joonkoo Park, now a postdoctoral fellow at Duke University, researchers used functional magnetic resonance imaging, or fMRI, to measure the brain activity of 27 healthy young adults while they performed simple numerical and arithmetic tasks. In one task, participants were asked to judge whether two groups of shapes contained the same or different numbers of items. In two other tasks, participants were asked to solve simple addition and subtraction problems.
Consistent with previous studies, the researchers found that the basic number-matching task activated the right parietal cortex, while the addition and subtraction tasks produced additional activity in the left parietal cortex. But they also found something new: During the arithmetic tasks, communication between the left and right hemispheres increased significantly compared with the number-matching task. Moreover, people who exhibited the strongest connection between hemispheres were the fastest at solving the subtraction problems.
"Our results suggest that subtraction performance is optimal when there is high coherence in the neural activity in these two brain regions. Two brain areas working together rather than either region alone appears to be key" said co-author Dr. Denise C. Park, co-director of the UT Dallas Center for Vital Longevity and Distinguished University Chair in the School of Behavioral and Brain Sciences. Park (no relation to the lead author) helped direct the study along with Dr. Thad Polk, professor of psychology at the University of Michigan.
Lead author Dr. Joonkoo Park points out that the findings suggest that disrupted or inefficient neural communication between the hemispheres may contribute to the impaired math abilities seen in dyscalculia, the numerical equivalent of dyslexia. "If such a causal link exists," he said, "one very interesting avenue of research would be to develop training tasks to enhance parietal connectivity and to test whether they improve numerical competence."
Such a training program might help develop math ability in children and could also help older adults whose arithmetic skills begin to falter as a normal part of age-related cognitive decline.
This research was supported by a grant to Dr. Denise C. Park from the National Institute on Aging.

Bankruptcy can be stressful and it can also bring relief. On one hand, having people go through all of your personal financial information can be formidable. On the other, however, after the bankruptcy has been discharged, you can get a fresh start and begin to re-build your credit. Continue reading to learn what you need to know to make your bankruptcy almost painless.
TIP! Always be honest with the information you give about your finances. Not only is hiding income and assets wrong, it is also a crime.
When consulting with your bankruptcy lawyer, be sure to disclose all of your significant debts. This obviously includes information on your credit card debts, medical bills, and other outstanding debts, but you should keep in mind that it also includes any loans that you have taken from relatives or friends.
If you need to file for bankruptcy, consider retaining a bankruptcy lawyer. Here are some of the things a qualified bankruptcy attorney can do for you: give you solid advice, simplify the complexity of the process, represent you in the courtroom. Attorneys can prepare your documents and help you with any concerns you may have.
If you have a co-debtor, consider the ramifications that filing a Chapter 7 bankruptcy will have. When you file under Chapter 7, you will no longer be legally responsible for any debts that were signed by yourself and a co-debtor. This does not dissolve any co-signers of the debt, and your creditors will continue to try and collect from them.
TIP! Once a person?s debts outstrip his or her ability to repay them, bankruptcy may be the only option left. If this sounds familiar, you should read up on the bankruptcy laws in your state.
Do not even think about paying your taxes with credit and petitioning for bankruptcy right after. In most states, this is not dischargeable debt. Therefore, you will end up owing the IRS a lot of money. Transferring the debt to another medium (e.g. a credit card) won?t magically make a tax debt discharagable, either. So it does not help you to put the tax bill on your charge card if you know the debt will be discharged anyway.
Bankruptcy is both a good and a bad thing; it depends on perspective. Regardless of your reason for filing, be aware information is the closest friend you have during the entire thing. The advice you have been provided with has probably helped you better understand bankruptcy. Make good use of these tips. You will be glad you did

MOGADISHU, Somalia (AP) ? Somalia's parliament Tuesday elected former labor minister Mohamed Osman Jawari as the new speaker, a key step toward the election of a president and the country's transition from a failed state to a nation with an effective government.
The process to select Somalia's next government has been criticized for corruption and threats of violence, international observers say. Nonetheless, some praise it as a watershed moment in the Horn of Africa nation's road to peace and stability.
While Somalia has had transitional administrations since 2004, it has not had a functioning central government since 1991, when warlords overthrew a longtime dictator and turned on each other, plunging the impoverished nation into chaos.
The last day of the eight-year U.N.-backed transitional government was Aug. 20 and the U.N. wanted a new president in place by then. But political bickering, violent threats and seat-buying schemes delayed progress toward the selection and seating of 275 members of the new Parliament that will select a president.
Jawari was elected the speaker of Parliament on Tuesday by just 228 legislators.
A group of Somali elders has been tasked with selecting the full list of 275 parliamentarians, but the election of the speaker went ahead without the complete number.
Jawari was challenged by Ali Khalif Galaydh, who had been Somalia's prime minister in 2000-2001 but led in the first round of voting. Galaydh pulled out in the second round, saying he favored Jawari for the post and Jawari was then declared the winner.
The U.N. special representative for Somalia, Augustine Mahiga, called Tuesday's election of a speaker "a moment of progress and optimism" and "an important step on the road to restoring accountable and participatory governance."
He said that some 260 members of Parliament have either been sworn in or are pending imminent ratification, and he urged that the 15 remaining lawmakers be selected and seated quickly so the election of a new president can take place "within 10 days."
Mahiga said the election of deputy speakers of Parliament will take place in the immediate future.
"The new federal Parliament must be allowed to exercise its authority with independence, transparency and free from undue influence and coercion," he said in a statement.
In a report to the U.N. Security Council circulated Tuesday, U.N. Secretary-General Ban Ki-moon said the final months of the transitional government were "fraught with setbacks" but also characterized by formidable Somali and international efforts to establish "a more legitimate and representative government with new leadership and representative government with new leadership and institutions."
He said the election of the speaker, deputy speakers and a president "will offer Somalia a leadership with a new mandate to continue working on the peace process and the reconstruction of the country."
But Ban predicted "a rough and unpredictable road ahead" and expressed serious concern at reports of "corrupt practices and intimidation by those seeking to influence the political process."
The secretary-general warned that "establishing and maintaining stability and security in Somalia will not be easy."
"Many spoilers fear that an orderly society with established institutions of governance and rule of law will compromise their ill-gained privileges," he said.
Ban urged Somalis "to rise up to the challenge and, jointly with their leaders, start building a peaceful and prosperous country."

TBILISI, Georgia (AP) ? A government official says Georgian forces have freed 10 people who were taken hostage by militants who illegally entered the country from the Russian republic of Dagestan.
Salome Makahkradze, a spokeswoman for Georgia's Interior Ministry, said the military operation against the militants at a Georgia-Russia border began Wednesday and was still under way. He said all the hostages have been released, but he refused to provide further details.
The Georgian TV station Imedi said several of the militants have been wounded in the fighting.
Georgia shares its northeastern border with Russia's Dagestan, which has been plagued by near-daily violence of Islamic militants.

NEW YORK (Reuters) - Some two dozen topless women protested in a New York City park on a hot, sweaty Sunday as part of what they called "National Go-Topless Day" to draw attention to inequality in topless rights between men and women. There were topless men in the park, too, but nobody paid them much attention, a disparity, organizers said, that demonstrated the need for the event. The topless women drew crowds of onlookers who took pictures and video with their cell phones. ...

You may not have noticed, but I?ve been gone for three weeks. Oh, I?ve been around, but a few weeks ago I decided to take a week-long blogging sabbatical to take care of some family matters. And then I got sick, and one week turned into three weeks. In retrospect, I needed those three weeks off to recharge and give myself a bit of a rest. Three years of blogging every day can certainly take a toll on you. But this less than voluntary break did take its toll on me.
In some ways, I really missed blogging, not just for the writing component of it, which I love, but also because of feeling disconnected from my blogging community. The members of that community have become a part of my daily life, and much of our online conversation takes place in the comments of various blogs. When that?s not happening, I definitely feel a void.
But while being disconnected for much of the time, and only on social media platforms for a limited amount of time, I gained a new sense of appreciation for the role that technology and the Internet play in our lives. Here are a few of my thoughts and observations:
1. The importance of connections ? When you?re laid up in bed for a bit, the outside world seems far away. While I didn?t get online much, I was touched by the private messages I got from a number of friends wondering what was wrong. I couldn?t always respond, but it was nice to have people checking in on me. The importance of this for those who are truly confined to their homes for longer periods of times or permanently is undeniable.
As for my family, my wife was down in NC with her parents for a week with no Internet access at all. The ability to text each other throughout the day was what kept us both sane.
And since I get Twitter DMs pushed to my phone, I even had the chance to meet a few online friends who were swinging through my town for a short period of time. Even though I felt horrible, it was worth dragging myself out of bed to meet them.
2. The importance of online information ? During the past month the Internet was a great source of info, from researching local retirement communities and nursing homes (not for me!) to laying in bed trying to figure out what was wrong with me, and to find the only 24-hour pharmacy in our area. When you?re in major pain in the middle of the night, you don?t want to lay in bed until morning in order to get your antibiotic and painkiller prescriptions!
3. The importance of mobile ? While I was laid up in bed, I didn?t have my computer, so in the middle of the night I was limited to my small 5? Samsung Galaxy Player (Android). It was a lifesaver. As I searched the Internet for information, I was grateful for mobile optimized sites, and painfully reminded of how difficult it is when a site you want to use doesn?t work well on mobile devices. The increased and rapid pace of mobile adoption by users makes it that much more important for businesses to make sure that their websites are ready for this shift. It?s already happening.
4. The failure of directory sites ? I?ve never been a fan of the online Yellow Pages or other directory sites, but my experiences during this time made me dislike them even more. Trying a simple search for ?24-hour pharmacy Lancaster PA? was excruciating. I kept getting directory lists of what SHOULD have been 24-hour pharmacies, but we only have one in the area. The directory listings did nothing but give me more lists of pharmacies, whether they were open 24 hours or not.
If you have a website, do your own optimization for search engines, and don?t waste your money on directory sites. Google is already a directory. Those directory sites do nothing but muddy up the digital waters.
5. The rapidly changing entertainment landscape ? During the past month, Netflix has been my best friend. My 5? tablet is perfect for watching videos, playing Words with Friends, and keeping up with other forms of entertainment, including the Olympics. Convergence is happening, and recent studies from Pew and others are showing some rather exciting possible futures for television and the entertainment industry. It?s pretty darn exciting, and we can?t even fathom where all of this will be in the next five years.
So I?m glad to be back, heading into a very busy Fall season with my work load and a heavier than normal teaching load. I?m looking forward to it, and now that I?m back on the blog, I?m also looking forward to really reconnecting with all of you.
Have you ever taken an involuntary break from the Internet and social media? Did it give you a new appreciation or fresh perspective on technology?

Visual Research Methods Visual data have been of concern to the social sciences in two ways: visual records produced by the investigator, and visual documents produced by those under study. In recent years, however, this dichotomy between the observer and the observed has begun to collapse (as it has across the qualitative social sciences more generally) and a third kind of visual record or, more accurately, representation, has emerged: the collaborative representation.
Thus visual anthropology and visual sociology proceed methodologically by making visual representations (studying society by producing images), by examining pre-existing visual representations (studying images for information about society), and by collaborating with social actors in the production of visual representations. Methodologically, the use of photography, film and video to document areas of social and cultural life would appear to be straightforward and un-problematic. Click here to read more?

It seems the newest member of HTC's mid-range smartphone line-up -- previously known as the Proto -- is actually the Desire X, according to several Scandinavian retailers (see coverage). Also, Hong Kong blog ePrice, who gave the new model the blurrycam treatment, claims that the specs line up with all the rumors: a 4-inch, 800 x 480 display, Android 4.0 with Sense 4.0, Beats Audio, dual-core 1Ghz processor and 5-megapixel camera. HTC should formally out the phone this week at IFA, but its European presence and similarity to the China-only New Desire V means it's likely an international version -- without the continental sticker shock.

Isaac threatens to become a Category 2 hurricane by mid week. Louisiana governor declares a state of emergency.
Tropical Storm Isaac lashed south Florida with winds and heavy rain on Sunday after battering the Caribbean, threatening to interrupt most U.S. offshore oil production in the Gulf of Mexico and disrupting plans for the Republican National Convention in Tampa.

Isaac is expected to strengthen to a Category 2 hurricane and hit the Gulf Coast somewhere between Florida and Louisiana at midweek - on or near the seventh anniversary of Hurricane Katrina - the U.S. National Hurricane Center (NHC) said in an advisory.
A hurricane warning was issued for the Gulf Coast from Louisiana to the Florida Panhandle, including New Orleans, which was devastated when Katrina struck the city on Aug. 29, 2005, killing more than 1,800 people and causing billions of dollars of damage to the Gulf Coast.
RECOMMENDED: Five ways to prepare for a hurricane
In Louisiana, Governor Bobby Jindal declared a state of emergency and said 15 low-lying parishes outside New Orleans' newly built, $14.5 billion flood defense system would likely be under mandatory evacuation orders by Monday.
"There's really nothing that's going to stop this storm from forming and from strengthening," said Jindal, a seasoned crisis manager who has weathered such disasters as the 2010 BP oil spill.
On Mississippi's Gulf Coast, residents started stocking up on supplies and securing their homes. "It is packed. They are clearing the shelves," said Lindy Stewart after shopping at a Sam's Club in Gulfport. Stewart said she bought bread, lunch meat and other "stuff you need to survive a couple of days without power."
The Mississippi State Port Authority ordered the port of Gulfport cleared of all cargo vessels and cargo containers.
Isaac is forecast to become a hurricane either late Monday or Tuesday. The NHC said Isaac was expected to eventually intensify to a Category 2 hurricane with "extremely dangerous" sustained winds of 105 miles per hour (169 kph) as it swept up the warm waters of the Gulf of Mexico.
Forecasters are predicting a more westward track that could bring Isaac over the heart of the U.S. offshore oil patch, which produces about 23 percent of U.S. oil output and 7 percent of its natural gas output.
SHUTTING OIL PRODUCTION
Meteorologists at Weather Insight, an arm of Thomson Reuters, predict the storm will spur short-term shutdowns of 85 percent of the U.S. offshore oil production capacity and 68 percent of the natural gas output.
With the threat to offshore oil infrastructure and Louisiana refineries, U.S. crude oil prices traded up 75 cents to $96.90 a barrel in Asia trading early Monday.

LOME, Togo (AP) ? The female wing of a civil rights group is urging women in Togo to stage a week-long sex strike to demand the resignation of the country's president.
Women are being asked to start withholding sex from their husbands or partners as of Monday, said Isabelle Ameganvi, leader of the women's wing of the group Let's Save Togo. She said the strike will put pressure on Togo's men to take action against President Faure Gnassingbe.
Ameganvi, a lawyer, told The Associated Press that her group is following the example of Liberia's women, who used a sex strike in 2003 to campaign for peace.
"We have many means to oblige men to understand what women want in Togo," Ameganvi said.
The sex strike was announced at a rally Saturday of several thousand in the capital city, Lome. The demonstration was organized by a coalition that is protesting recent electoral reforms, which they say will make it easier for Gnassingbe's party to win re-election in the parliamentary polls set for October.
Gnassingbe came to power in 2005, following the death of his father, Eyadema Gnassingbe, who ruled the West African country for 38 years. Gnassingbe has not commented on the sex strike, nor has his wife. Earlier this month, two anti-Gnassingbe protests were dispersed by police using tear gas and more than 100 people were arrested.
At Saturday's rally, which ended peacefully, Jean-Pierre Fabre, leader of the National Alliance for Change opposition party, called for Gnassingbe's resignation. Other opposition leaders called for civil disobedience.
But it is the sex strike that has people talking in this small country of more than 6 million people.
"It's a good thing for us women to observe this sex strike as long as our children are in jail now. I believe that by observing this, we will get them released," Abla Tamekloe said. "For me, it's like fasting, and unless you fast, you will not get what you want from God."
When asked if her husband would agree, Tamekloe said: "It is easy for me to observe it. I am used to it, but I am not sure my husband will accept, but I have to explain to him."
Another Togolese woman said she supports the sex strike, but she does not know if she can carry it out for a full week.
"I do agree that we women have to observe this sex strike but I know my husband will not let me complete it. He may agree at first, but as far as I know him, he will change overnight," Judith Agbetoglo said. "So I don't believe I can do the one-week sex strike. Otherwise, I will have serious issues with him. He likes that too much."
Though the call for a sex strike seemed to please many women, some men, including heads of opposition parties and human rights groups in the anti-Gnassingbe coalition, did not believe it would be a success.
"One week sex strike is too much," said Fabre of the National Alliance for Change, who suggested a shorter period, amid laughter from the crowd at the demonstration. "Let's go for only two days".
Others were skeptical of Isabelle Ameganvi's call.
"It is easy for her to say because she is not married herself. She does not live with a man at home," said Ekoue Blame, a Togolese journalist. "Does she think women who live with their husband will be able to observe that? By the way, who controls what couples do behind closed doors?"

When Neil Armstrong walked on the moon all those years ago, he made his country believe that anything was possible with ingenuity and dedication ? and in the process became one of America's greatest heroes, his friends, colleagues and admirers said Saturday after news that the former astronaut had died.
"When I think of Neil, I think of someone who for our country was dedicated enough to dare greatly," said former astronaut John Glenn, who went through jungle training in Panama with Armstrong as part of the astronaut program and was a close friend. He said Armstrong showed exemplary skill and dedication.
The idea of Armstrong as a humble pilot who served his country above all echoed around the country Saturday, by visitors to museums that fete his accomplishments and by his former NASA colleagues. Armstrong died Saturday at age 82 from complications resulting from cardiovascular procedures, his family said.
In California, visitors and staff at the Griffith Observatory paused for a moment of silence. At the Armstrong Air and Space Museum in Armstrong's hometown of Wapakoneta, Ohio, a black ribbon hung over a plaque of Armstrong in the museum's entryway and a U.S. flag was lowered in Armstrong's memory.
Tourist Jonathon Lack, a judge from Anchorage, Alaska, said he decided to visit the Air and Space Museum in Washington, D.C., after hearing of Armstrong's death.
"What really hit me is that he was in his 30s when he walked on the moon," said Lack, who is 42. "That made me think about how little I've done."
He saw in Armstrong's death a reminder of an America where people dreamed big things and sought to accomplish the inconceivable.
Armstrong commanded the Apollo 11 spacecraft that landed on the moon July 20, 1969, capping the most daring of the 20th-century's scientific expeditions during the climax of a heated space race with the Soviet Union.
Armstrong and Buzz Aldrin spent nearly three hours walking on the lunar surface, collecting samples, conducting experiments and taking photographs. Aldrin, who became the public face of the moon landing after shy Armstrong recoiled from the public eye, said his colleague's leap changed the world forever and became a landmark moment in human history.
"Whenever I look at the moon, it reminds me of the moment over four decades ago when I realized that even though we were farther away from Earth than two humans had ever been, we were not alone," he said. "Virtually the entire world took that memorable journey with us. I know I am joined by millions of others in mourning the passing of a true American hero and the best pilot I ever knew."
The third astronaut on the mission, Michael Collins, circled the moon in the mother ship 60 miles overhead while the other two went to the surface. "He was the best, and I will miss him terribly," Collins said, according to NASA's website.
The Apollo 11 command module Columbia is on display at the Air and Space Museum, and visitors there Saturday gathered around it to remember Armstrong and his accomplishments.
Bob Behnken, the chief of the NASA Astronaut Office, said Armstrong's historic step was the reason many became astronauts.
"Neil Armstrong was a very personal inspiration to all of us within the astronaut office," he said. "The only thing that outshone his accomplishments was his humility about those accomplishments. "
Daniel Zhou, a student at Armstrong's alma mater Purdue University in Indiana and a member of Students for the Exploration and Development of Space, said Saturday was sad day.
"He will always be a source of inspiration for our generation, and for the generations to come, as we ask ourselves, 'Why explore space?'" Zhou said.
At New York's Intrepid Sea, Air and Space Museum, a 1960 photo of Armstrong hangs near the space shuttle Enterprise ? showing a youthful NASA pilot standing and smiling next to the X-15 rocket plane he was testing.
On Saturday afternoon, many among the hundreds of visitors filing past the mammoth white display didn't know he had died.
'I'm shocked!" said Dennis McKowan, 49, a computer network engineer from Sunnyvale, Calif., on a business trip to New York. "I used to skip school to watch the Apollo launches."
He was a child when he watched the moon landing.
"How do you top that? No one has gone farther yet."

Stowers Institute for Medical Research
KANSAS CITY, MOTwo opposing teams battle it out to regulate gene expression on the DNA playing field. One, the activators, keeps DNA open to enzymes that transcribe DNA into RNA. Their repressor opponents antagonize that effort by twisting DNA into an inaccessible coil around histone proteins, an amalgam called chromatin, effectively blocking access to DNA by enzymes that elongate an RNA strand.
Both teams maneuver by chemically modifying histonesthe activators by decorating histones with acetyl groupslet's call them green flagscausing them to loosen their grip on DNA. The repressors retaliate by marking histones with red flags, often methyl groups, which call in de-acetylase enzymes to clip off the green flags, restore the chromatin barrier and end that round of gene expression. Disturbing this biochemical balance lies at the heart of many diseases, particularly cancer.
Recently, the lab of Jerry Workman, Ph.D., investigator at the Stowers Institute for Medical Research, reported in the journal Nature that a reserve of "pre-acetylated" histones sits on the chromatin sidelines ready to sub for histones whose green flags get clipped by repressors, a tactic aiding the activators called "histone exchange". In a companion study published in the Aug. 26, 2012 Advance Online Publication of Nature Structural & Molecular Biology the Workman lab now shows that a repressor called Set2 in yeast recruits a protein assistant to block the histone exchange. That study reveals a heretofore unknown mechanism to keep gene activation under control and ensure that erroneous transcription does not occur.
"Accurate gene expression is critical for normal cell function, and when this control is lost cells grow abnormally," says Workman. "These two studies identify mechanisms used by cells to regulate gene expression, which is important for our understanding of what goes wrong in diseases marked by unregulated cell growth, like cancer."
The study began when the group, in collaboration with Stowers proteomics experts Michael Washburn, Ph.D., and Laurence Florens, Ph.D., applied mass spectrometry analysis to identify any protein expressed in yeast Saccharomyces cerevisiae that bound to chromatin in regions patrolled by Set2. Those regions were readily apparent by the presence of Set2's red flag methyl group planted in a specific histone protein interacting with DNA.
"We knew that Set2 added this mark in the middle and downstream parts of genes to recruit de-acetylases," says the study's lead author Michaela Smolle, Ph.D., a postdoctoral researcher in the Workman lab. "But the proteomic search allowed us to cast a wide net for other proteins associated with that marka bit like fishing."
Among the fish caught was a component of a yeast chromatin "remodeler" known as Isw1, providing circumstantial evidence that the Set2 red flag attracts Isw1 as well as de-acetylases. Additional genomic experiments evaluating the entire genome of a yeast mutant lacking Set2 supported that idea: not only were the red methyl flags missing but the chromatin landscape was devoid of Isw1 as well.
To assess Isw1's biological function the group exploited yet another yeast mutant, this one lacking the ISW1 gene itself. Microarray analysis of global transcription in ISW1 CHD1 mutants showed widely perturbed gene expression marked by aberrant expression of RNA snippets rather than complete transcripts. Biologists view the presence of such "cryptic transcripts" as indicators of cellular stress.
Analysis of acetylation and methylation patterns in chromatin of ISW1 mutants revealed the probable cause: mutants showed ramped up histone exchange activity marked by excessive levels green-flagged pre-acetylated histones along the length of many genes, a condition likely favoring initiation of truncated RNAs.
"Our work shows that the Set2 methylation mark plays two important roles to ensure that RNA transcription starts only at the beginning of the gene and not in the middle," says Workman. "On one hand, it recruits Isw1 to block incoming histones, and on the other it also recruits a deacetylase to remove any acetylation marks that might happen to have sneaked in."
The Workman lab uses yeast, fruit flies and mammalian cells to study multiple factors that activate and repress transcription. Thus far, they have characterized players in the repressive Set2 pathway primarily in yeast, in part because yeast represents an ideal organism for mutational analysis and has a fairly small genome6,000 genes compared to the 25,000 or so in humans or mice.
Smolle notes that although yeast genomes are simpler, the principles that govern Set2 activity in yeast will likely hold true for its human counterparts, among them the human protein SETD2. "Yeast has a single methylase, while humans have several, and flies and humans have several Isw1-like proteins," she says. "While you cannot equate one with the other precisely, you can be reasonably sure that what happens in yeast happens in humans as well but tends to be more complicated."
Workman agrees, adding that these discoveries have significant implications for human disease. "Strikingly, the human homolog of Set2, SETD2, is implicated as a tumor suppressor in breast cancer and in renal carcinoma, and those cells are deficient in the SETD2 methylation mark," he says. "These findings strongly suggest that SETD2 could be important in controlling cell growth and preventing tumors. Thanks to yeast, we now know more about how Set2 does that."

ScienceDaily (Aug. 23, 2012) ? Applied physicists at the Harvard School of Engineering and Applied Sciences (SEAS) have created an ultrathin, flat lens that focuses light without imparting the distortions of conventional lenses.
At a mere 60 nanometers thick, the flat lens is essentially two-dimensional, yet its focusing power approaches the ultimate physical limit set by the laws of diffraction.
Operating at telecom wavelengths (i.e., the range commonly used in fiber-optic communications), the new device is completely scalable, from near-infrared to terahertz wavelengths, and simple to manufacture. The results have been published online in the journal Nano Letters.
"Our flat lens opens up a new type of technology," says principal investigator Federico Capasso, Robert L. Wallace Professor of Applied Physics and Vinton Hayes Senior Research Fellow in Electrical Engineering at SEAS. "We're presenting a new way of making lenses. Instead of creating phase delays as light propagates through the thickness of the material, you can create an instantaneous phase shift right at the surface of the lens. It's extremely exciting."
Capasso and his collaborators at SEAS create the flat lens by plating a very thin wafer of silicon with an nanometer-thin layer of gold. Next, they strip away parts of the gold layer to leave behind an array of V-shaped structures, evenly spaced in rows across the surface. When Capasso's group shines a laser onto the flat lens, these structures act as nanoantennas that capture the incoming light and hold onto it briefly before releasing it again. Those delays, which are precisely tuned across the surface of the lens, change the direction of the light in the same way that a thick glass lens would, with an important distinction.
The flat lens eliminates optical aberrations such as the "fish-eye" effect that results from conventional wide-angle lenses. Astigmatism and coma aberrations also do not occur with the flat lens, so the resulting image or signal is completely accurate and does not require any complex corrective techniques.
The array of nanoantennas, dubbed a "metasurface," can be tuned for specific wavelengths of light by simply changing the size, angle, and spacing of the antennas.
"In the future we can potentially replace all the bulk components in the majority of optical systems with just flat surfaces," says lead author Francesco Aieta, a visiting graduate student from the Universit? Politecnica delle Marche in Italy. "It certainly captures the imagination."
Aieta's and Capasso's coauthors at SEAS included postdoctoral research associates Patrice Genevet and Nanfang Yu (Ph.D. '09), graduate students Mikhail A. Kats and Romain Blanchard, and visiting scholar Zeno Gaburro.
The work was supported by the National Science Foundation (NSF), the NSF-funded Harvard Nanoscale Science and Engineering Center, and the Center for Nanoscale Systems at Harvard (a member of the NSF-supported National Nanotechnology Infrastructure Network). The researchers also individually received support from the Robert A. Welch Foundation, the European Communities Seventh Framework Programme, and an NSF Graduate Research Fellowship.

SHELBY, N.C. -- Andrew Mendoza and Anthony Timmons combined on a three-hit shutout to lift Lakewood, Calif., to a 4-0 victory that eliminated Milford from the American Legion World Series Saturday.
Sean Cameron had two of Milford's three hits. The other came from Ed Michaud. Post 196, which went 10-0 to win the the Connecticut and Northeast Region championship, finishes 28-8.
Mendoza and Kyle Clary hit a pair of doubles as Lakewood took a 4-0 lead against Milford starter Cody Hadden after two innings.
Three of those runs scored on a pair of wild pitches and an error.
Milford reliever Jacob Saley pitched a three-hit shutout through the final six innings, but Milford's lineup never got a runner past second base.
Mendoza allowed just two hits and struck out 5 in 6 1/3 innings before Timmons closed the game.
He allowed just one hit and struck out two.
