Wladimir Klitschko to fight Povetkin in October

(AP) ? Wladmir Klitschko will defend his multiple heavyweight titles against mandatory challenger Alexander Povetkin in a highly anticipated showdown on Oct. 5 in Moscow.

Klitschko's management says the fight, long in the making, will take place in the Olympic Arena.

"This is the best fight that the heavyweight division has to offer at the moment," Klitschko said in a statement Tuesday.

Klitschko holds the IBF and IBO belts and is also the WBO and WBA "super champion." Povetkin, 33, is WBA's "regular champion."

Klitschko's older brother Vitali is the WBC champion. The Ukraine-born brothers have dominated the heavy division for a decade.

Russia's Povetkin is like Wladimir Klitschko a former Olympic champion and has a 26-0 record, with 18 KOs.

Klitschko is 60-3. His last fight was a sixth-round TKO over Francesco Pianeta in May.

The Klitschkos rarely fight outside Germany, their base.

"I've never boxed in Moscow and I'm looking forward to many Ukrainians and Russians who will come to the arena and create a special atmosphere," Klitschko said.

Povetkin, who beat Ruslan Chagaev on points in August 2011 for the then-vacant title, also last fought in May and stopped Polish challenger Andrzej Wawrzyk in the third round for his fourth successful title defense.

Klitschko, 37, will be in his 24th title fight.

Brain differences seen in depressed preschoolers

July 1, 2013 ? A key brain structure that regulates emotions works differently in preschoolers with depression compared with their healthy peers, according to new research at Washington University School of Medicine in St. Louis.

The differences, measured using functional magnetic resonance imaging (fMRI), provide the earliest evidence yet of changes in brain function in young children with depression. The researchers say the findings could lead to ways to identify and treat depressed children earlier in the course of the illness, potentially preventing problems later in life.

"The findings really hammer home that these kids are suffering from a very real disorder that requires treatment," said lead author Michael S. Gaffrey, PhD. "We believe this study demonstrates that there are differences in the brains of these very young children and that they may mark the beginnings of a lifelong problem."

The study is published in the July issue of the Journal of the American Academy of Child & Adolescent Psychiatry.

Depressed preschoolers had elevated activity in the brain's amygdala, an almond-shaped set of neurons important in processing emotions. Earlier imaging studies identified similar changes in the amygdala region in adults, adolescents and older children with depression, but none had looked at preschoolers with depression.

For the new study, scientists from Washington University's Early Emotional Development Program studied 54 children ages 4 to 6. Before the study began, 23 of those kids had been diagnosed with depression. The other 31 had not. None of the children in the study had taken antidepressant medication.

Although studies using fMRI to measure brain activity by monitoring blood flow have been used for years, this is the first time that such scans have been attempted in children this young with depression. Movements as small as a few millimeters can ruin fMRI data, so Gaffrey and his colleagues had the children participate in mock scans first. After practicing, the children in this study moved less than a millimeter on average during their actual scans.

While they were in the fMRI scanner during the study, the children looked at pictures of people whose facial expressions conveyed particular emotions. There were faces with happy, sad, fearful and neutral expressions.

"The amygdala region showed elevated activity when the depressed children viewed pictures of people's faces," said Gaffrey, an assistant professor of psychiatry. "We saw the same elevated activity, regardless of the type of faces the children were shown. So it wasn't that they reacted only to sad faces or to happy faces, but every face they saw aroused activity in the amygdala."

Looking at pictures of faces often is used in studies of adults and older children with depression to measure activity in the amygdala. But the observations in the depressed preschoolers were somewhat different than those previously seen in adults, where typically the amygdala responds more to negative expressions of emotion, such as sad or fearful faces, than to faces expressing happiness or no emotion.

In the preschoolers with depression, all facial expressions were associated with greater amygdala activity when compared with their healthy peers.

Gaffrey said it's possible depression affects the amygdala mainly by exaggerating what, in other children, is a normal amygdala response to both positive and negative facial expressions of emotion. But more research will be needed to prove that. He does believe, however, that the amygdala's reaction to people's faces can be seen in a larger context.

"Not only did we find elevated amygdala activity during face viewing in children with depression, but that greater activity in the amygdala also was associated with parents reporting more sadness and emotion regulation difficulties in their children," Gaffrey said. "Taken together, that suggests we may be seeing an exaggeration of a normal developmental response in the brain and that, hopefully, with proper prevention or treatment, we may be able to get these kids back on track."

Funding for this study comes from the National Institute of Mental Health (NIMH) of the National Institutes of Health (NIH). It also was supported by the Klingenstein Third Generation Foundation and the Communities Healing Adolescent Depression and Suicide (CHADS) Coalition for Mental Health. NIH Grant number K23 MH098176.

People show more humorous creativity when primed with thoughts of death

July 2, 2013 ? Humor is an intrinsic part of human experience. It plays a role in every aspect of human existence, from day-to-day conversation to television shows. Yet little research has been conducted to date on the psychological function of humor. In human psychology, awareness of the impermanence of life is just as prevalent as humor. According to the Terror Management Theory, knowledge of one's own impermanence creates potentially disruptive existential anxiety, which the individual brings under control with two coping mechanisms, or anxiety buffers: rigid adherence to dominant cultural values, and self-esteem bolstering.

A new article by Christopher R. Long of Ouachita Baptist University and Dara Greenwood of Vassar College is titled Joking in the Face of Death: A Terror Management Approach to Humor Production. Appearing in the journal HUMOR, it documents research on whether the activation of thoughts concerning death influences one's ability to creatively generate humor. As humor is useful on a fundamental level for a variety of purposes, including psychological defense against anxiety, the authors hypothesized that the activation of thoughts concerning death could facilitate the production of humor.

For their study, Long and Greenwood subdivided 117 students into four experimental groups. These groups were confronted with the topics of pain and death while completing various tasks. Two of the test groups were exposed unconsciously to words flashed for 33 milliseconds on a computer while they completed tasks -- the first to the word "pain," the second to the word "death." The remaining two groups were prompted in a writing task to express emotions concerning either their own death or a painful visit to the dentist. Afterward, all four groups were instructed to supply a caption to a cartoon from The New Yorker.

These cartoon captions were presented to an independent jury who knew nothing about the experiment. The captions written by individuals who were subconsciously primed with the word death were clearly voted as funnier by the jury. By contrast, the exact opposite result was obtained for the students who consciously wrote about death: their captions were seen as less humorous.

Based on this experiment, the researchers conclude that humor helps the individual to tolerate latent anxiety that may otherwise be destabilizing. In this connection, they point to previous studies indicating that humor is an integral component of resilience.

In light of the finding that the activation of conscious thoughts concerning death impaired the creative generation of humor, Long and Greenwood highlight the need for additional research, not only to explore the effectiveness of humor as a coping mechanism under various circumstances, but also to identify its emotional, cognitive, and/or social benefits under conditions of adversity.

(AP) ? Cristiano Gulias took a deep drag from his mini-cigar and did the unthinkable ? he started a political discussion in a coffee shop the morning after Brazil's national soccer team won a major championship.

Call it a post-protest phenomenon, the rapid politicization of a nation whose people have finally "awakened," as millions of Brazilians chanted during hundreds of protests over the past two weeks.

Political observers in Brazil say that President Dilma Rousseff, following a perplexing week of silence after massive protests broke out on June 17, now better understands the powerful political wave that has swept Brazil and is responding to it. Her actions have helped temporarily take the fire out of the movement.

"Now is the time for the people to sit and bargain with our leaders," Gulias, 84, who strongly supports the protests, said at a Sao Paulo coffee shop as another regular nodded his head in agreement. "We're fighting for the fulfillment of a million broken promises politicians have given us. We've demanded that our voices be heard."

Despite a poll showing a plunge in her popularity, some argue Rousseff has started to rebound by showing Gulias and other citizens that she wants them to be heard within a political system virtually all Brazilians complain has long since stopped listening to them.

On Tuesday, the president will deliver to congress her recommendations on what items should be included in a national plebiscite on political reform.

That's helped end the massive size of the protests, though they are still seen each day in a smaller and scattered fashion. On Tuesday, truckers protesting against highway tolls blocked roads in eight states, crippling traffic in some areas.

Also helping Rousseff is the end of the high-profile Confederations Cup soccer tournament this past weekend, which Brazil won, and the beginning of the South American nation's winter school vacation. The tournament angered citizens upset with the billions of dollars spent on stadiums while they endure underfunded schools and hospitals, and the protests were originally organized by university students.

"She took her time, but since first responding Dilma is giving answers and putting forward proposals that address protesters' concerns," said Helena Singer, a sociologist and professor at the University of Sao Paulo. "Her strong backing of political reform was bold. She's made proposals on health care and education that were on the demonstrators' agenda. The worst thing she did was to delay, but she's responding to the protesters now."

In addition to pushing congress to approve a plebiscite giving Brazilians the chance to vote on what sort of political reform they want to see, Rousseff also says she wants oil royalties used to fund education, announced $23 billion in new spending on urban transportation, and she said she'll import thousands of foreign doctors to work in underserved, poor areas.

She has ordered her Cabinet to focus on and devise solutions for five priority areas: fiscal responsibility and controlling inflation, political reform, health care, public transport and education.

All those moves helped calm the waters. While not offering immediate solutions to the problem of Brazil's poor public services, they at least gave protesters the sense that she was listening to them and starting to work on their demands.

The biggest danger facing Rousseff and the tenuous truce protesters seem to have given her is an area where her government has garnered the most criticism: its economic policy, which many say gives the state too big of a role, scaring away international investors in the short term and ultimately hobbling the nation's ability to economically evolve and become more competitive.

"None of Dilma's proposals address the underlying problem that the economic policy of her government seems lost, it's not effective," said Alexandre Barros, with the Early Warning political risk group in Brasilia. "The economy isn't growing and prices are rising. People can no longer consume as much as they want, creating anger and fear in the middle class."

A new poll from the respected Datafolha published Sunday in the Folha de S.Paulo newspaper backs that up. It shows that 38 percent of Brazilians think their spending power is on the decline, up from 25 percent a year ago. It also showed 44 percent think unemployment will rise, 13 percentage points higher than a year back.

The same poll found that 30 percent of respondents rated Rousseff's government as "great/good," a sharp fall from the 57 percent who gave it that rating three weeks ago before the demonstrations began.

Datafolha interviewed 4,717 people on June 27 and 28. The poll had a margin of error of 2 percentage points.

The U.S.-based political risk consulting firm Eurasia Group said in a Monday research note that the poll numbers mark "the end of a cycle of politics in which incumbents held absurdly high approval ratings, but it doesn't mean Rousseff is politically dead."

For now, Brazilians largely seem to be working to digest the upheaval seen and anger vented on the streets during the protests. They appear willing to give Rousseff the chance to respond, though the patience will not be long-lived.

"I don't think there is any consensus among the people of what all of this yet means," said Marcia Shimabukoro, a 22-year-old university student in Sao Paulo. "Before, we all felt alone and unable to provoke change. Now, we've shown we can become a powerful mass that must be heard. It's a cultural shift for my generation."

Lonesome George, the Iconic Gal pagos Tortoise, Gets Prepared for Taxidermy [Video]

The world?s most famous tortoise will soon make a return to public display?in mounted form.

The last of his species, Lonesome George was an icon for conservation and evolution. He was found alone on Pinta Island, part of the Gal?pagos archipelago, in 1971?human hunting and introduced goats had destroyed his kind and his habitat. So conservationists transported the 90-kilogram (200-pound) reptile to the Charles Darwin Research Station on Santa Cruz Island. Although two females of a closely related subspecies from Isabella Island kept him company, sadly, no eggs ever successfully hatched.

After his death in June 2012 (he was believed to be at least 100 years old), researchers froze his body and shipped him to the American Museum of Natural History in New York City, whose skilled taxidermists will preserved him for posterity. He will go on display at the museum in the winter before returning home to the Gal?pagos.

The nearly six-minute video outlines the preparation, which includes figuring out how best to pose and mount him?which is more complicated than you?d think.

Kelly Olynyk: A good pick for the Boston Celtics?

Kelly Olynyk was a break-out star at Gonzaga University this year. But is Kelly Olynyk, a 7-foot forward, a good choice for the Boston Celtics?

By David Clark Scott,?Staff writer / June 29, 2013

Gonzaga's Kelly Olynyk scores against Santa Clara during a January 2013 NCAA college basketball game in Santa Clara, Calif. Olynyk was chosen by the Boston Celtics in the first round of the NBA Draft.

There are no sure things in any NBA draft. The parquet floors of the NBA are littered with the shattered hopes and dreams of top draft picks.

But there's good reason for Celtics fans to be optimistic about center/power forward Kelly Olynyk. And let's face it, with the departure of Doc Rivers, Paul Pierce, and Kevin Garnett, Boston fans are searching for a silver lining.

Here's why Celtics general manager Danny Ainge traded up in the draft in order to get Olynyk.

Olynyk's no Kevin Garnett but he brings some needed size inside. At 7 feet, 234 pounds, he's a presence in the paint. He's smart (the son of a coach). He's a very efficient shooter, especially inside.

"This season, he took 63% of his shots at the rim and made 73% of them. Owning a variety of weird moves in the post, Olynyk has found many ways to be one of the most efficient players in the country, as he leads the NCAA in PER [Player Efficiency Rating] at 36.2.," points out Sam Vecenie of SB Nation.??

There are some who suggest that Olynyk may be a one-season wonder. He red-shirted in his junior year at Gonzaga to bulk up to play the post position. That turned out to be an intelligent move. He also has some international experience under his belt because he played with Canada's national basketball team while they were preparing for the Olympics.

While he's built to play the post, he's also got a 20-foot jump shoot ? something every successful big man in the NBA has today.?

Olynyk's weaknesses?

Well, Kevin O'Connor of?the Celtics Blog on SB nation is blunt in his assessment:

"His defensive game is nonexistent and he lacks the athletic tools to improve there. He's also not very good on the boards and gets pushed around despite his size. Olynyk lacks the athleticism to move side-to-side defensively, making him a liability in the pick-and-roll. Despite standing at 7-feet tall, he hasn't shown the ability to be a good rebounder at the next level."

Still, on balance, O'Connor likes Ainge's choice.

Taking his strengths, weaknesses, and long, floppy locks into account, what makes Olynyk a good fit for the Celtics?

Ainge is reportedly rebuilding the team around Rajon Rondo ? the one player he says he won't trade ? as well as Jeff Green and Avery Johnson. Ainge will likely use Jared Sullinger and Olynyk to fill the big power-forward shoes left by the departing Kevin Garnett.?

There's no question that this will be a rebuilding year for the Celtics. They will lose a lot of games, and fans will pin for the days of Rivers, Garnett, and Pierce.

But what Ainge finds appealing about Olynyk is that, unlike a lot of college draft picks, he can play in the NBA now. He has the size and shots. But he also has some room for improvement.

Boston.com sports writer Gary Dzen lists five reasons the Celtics took Olynyk, including this one:

"Olynyk is unorthodox, but he's gotten it done at a very high level for Gonzaga. There are two schools to drafting, and the Celtics seem to be moving away from the school of best athlete wins the day. JaJuan Johnson, who was the Celtics' pick in the 2011 draft, had the body but never developed the game.... On the other side, Jared Sullinger, Glen Davis, and Nate Robinson are examples of unorthodox Celtics players who have produced. Boston knows Olynyk can play."

And Olynyk's coach at Gonzaga, Mark Few, tells the Boston Herald's Tom Layman that his former big man has the intangibles to succeed with the Celtics.

?I think he?s a highly competitive person and player,? Few said. ?I think it?s not something he will fear and it will be something he will look forward to. You just put him on the floor and he?s going to do whatever it takes to win.?
