CHICAGO, IL Get out there and regularly kick that soccer ball around with your kids, you may be helping them prevent a broken hip when they are older, say researchers presenting their work at the American Orthopaedic Society for Sports Medicine's Specialty Day in Chicago, IL.

"According to our study, exercise interventions in childhood may be associated with lower fracture risks as people age, due to the increases in peak bone mass that occurs in growing children who perform regular physical activity," said lead author, Bjorn Rosengren, MD, PhD of Skane University Hospital, Malmo, Sweden.

Rosengren and his colleagues conducted a population-based controlled exercise intervention for six years in children age 7-9 years in Malmo, Sweden. In the intervention group 362 girls and 446 boys received 40 minutes of daily physical education at school. The control group of 780 girls and 807 boys received 60 minutes of physical education per week. Researchers registered incident fractures in all participants and followed skeletal development annually. During the time of the study there were 72 fractures in the intervention group and 143 in the control group resulting in similar fracture risks. The increase in spine bone mineral density was higher in both the boys and girls in the intervention group.

During this same time, researchers performed a retrospective cross-sectional study of 709 former male athletes with a mean age of 69 years and 1,368 matched controls with a mean age of 70 years to determine how many had suffered fractures and rates of bone density loss. Within the former athletes group, bone mass density dropped only minimally from +1.0 to +0.7 standard deviations compared to the control group.

"Increased activity in the younger ages helped induce higher bone mass and improve skeletal size in girls without increasing the fracture risk. Our study highlights yet another reason why kids need to get regular daily exercise to improve their health both now and in the future," said Rosengren.

Parent induces guilt, child shows distress

Mar. 22, 2013 ? The use of guilt-inducing parenting in daily parent-child interaction causes children distress still evident on the next day, finds a new study carried out by Kaisa Aunola, Asko Tolvanenen, Jaana Viljaranta and Jari-Erik Nurmi at the University of Jyv?skyl?, Finland.

According to the study, the use of guilt-inducing parenting varied from one day to another. When parents used higher levels of guilt-inducing parenting on certain days, this was evident as atypically high levels of distress and anger among children still on the next day.

In guilt-inducing parenting, a parent tries to impact on the child?s behavior using psychological means rather than direct limit setting. For example, the parent may remind the child how much he or she makes effort for the child or show how ashamed she/he is because of the child?s behaviour. This kind of parenting is typical for parents who are themselves distressed or exhausted. The research by Aunola et al. showed that although the guilt-inducing parenting by both the mother and the father increased the child?s daily distress, the role of the father was especially important.

The research project lead by Professor Kaisa Aunola was funded by the Academy of Finland and the Jacobs Foundation. In the project, the daily interaction between about 150 children and their parents and teachers was followed up across the first grade of primary school using the diary method.

Cosmos Might Be A Few Million Years Older Than Advertised

Planck's view of the Cosmic Microwave Background.

Planck's view of the Cosmic Microwave Background.

European Space Agency

The universe is a bit older than we thought, according to a group of European scientists who say they've snapped the most detailed image to date of the afterglow of the Big Bang.

Their picture is a more refined look at the Cosmic Microwave Background, or CMB, the ambient thermal radiation that's left over from the birth of the universe. The CMB was discovered by accident in 1964 and its glow was first imaged a quarter-century later by the Cosmic Background Explorer (COBE). Since then, another probe, known as WMAP, has also taken a picture of the CMB.

According to a statement released by the European Space Agency, Planck's look at the CMB:

"... is based on the initial 15.5 months of data from Planck and is the mission's first all-sky picture of the oldest light in our Universe, imprinted on the sky when it was just 380,000 years old."

The scientists say their new data shows the universe is 13.82 billion years old, slightly more antiquated than the commonly accepted figure of 13.77 billion years, a difference of about 50 million years. (For comparison, the difference is roughly equivalent to being off by about three months on the age of an 80-year-old person).

The standard model of cosmology posits that fluctuations in the CMB produced the "seeds" that eventually sprouted stars and galaxies. It also says that the universe expanded at a dramatic pace during an infinitesimally brief period known as inflation, right after the Big Bang.

NPR science correspondent Geoff Brumfiel says that the new map "shows tiny fluctuations that provide new information about the universe [and] ... also confirms previous measurements showing that matter only makes up about a 20th of the known universe."

According to The Associated Press:

"[Planck] also found that the cosmos is expanding a bit slower than originally thought, has a little less of that mysterious dark energy than astronomers figured and a tad more normal matter. But scientists say those are small changes in calculations about the cosmos, nothing dramatic when dealing with numbers so massive.

" 'We've uncovered a fundamental truth of the universe,' said George Esfthathiou, director of the Kavli Institute for Cosmology at the University of Cambridge who announced the Planck satellite mapping. 'There's less stuff that we don't understand by a tiny amount.'"

[Update at 1:00 p.m. ET: While an older universe may have implications for the science world, it's also a challenge to folks here at NPR. As physicist, astronomer and veteran NPR blogger Marcelo Gleiser points out, a name change might be in the cards for our science blog, "13.7: Cosmos and Culture."]

Can intraplate earthquakes produce stronger shaking than at plate boundaries?

Mar. 20, 2013 ? New information about the extent of the 1872 Owens Valley earthquake rupture, which occurs in an area with many small and discontinuous faults, may support a hypothesis proposed by other workers that these types of quakes could produce stronger ground shaking than plate boundary earthquakes underlain by oceanic crust, like many of those taking place along the San Andreas fault.

Published estimates of the 1872 Owens Valley earthquake in southeastern California put the quake at a magnitude 7.4-7.5 to 7.7-7.9. Early work indicates the Owens Valley fault is ~140 kilometers long, and ~113 kilometers ruptured in 1872. Recent work comparing magnitude estimates from reported shaking effects versus fault rupture parameters suggests that the Owens Valley surface rupture was either longer than previously suspected, or that there was unusually strong ground shaking during the event. Colin Amos of Western Washington University and colleagues tested the hypothesis that the 1872 rupture may have extended farther to the south in Owens Valley. They conclude that the 1872 Owens Valley earthquake did not trigger additional rupture in the Haiwee area, indicating that the 1872 rupture was not likely significantly longer than previously reported.

Amos and colleagues dug trenches in the southwestern Owens Valley area to look at the prominent Sage Flat fault east of Haiwee Reservoir. The trench data, combined with dating of the exposed sediment, allowed them to preclude the southern extent of the 1872 rupture from the Sage Flat area and identify two other much older surface-rupturing earthquakes in the area 25,000 to 30,000 years ago. The evaluation of their trench site suggests that the only recent ground disturbance, possibly coincident with the 1872 earthquake, was mostly weak fracturing that may have resulted from ground shaking -- rather than triggered slip along a fault. Soil liquefaction -- the conversion of soil into a fluid-like mass during earthquakes -- likely occurred at other nearby saturated wetlands and meadows closer to the axis of the valley.

East Greensboro Performing Arts Center: Last Night's City Council ...

From the News & Record:

"Leaders of the groups synerG Young Professionals, Greensboro Jaycees, the Future Fund, Face to Face and the young lawyers section of the Greensboro Bar Association presented the City Council on Tuesday with a white paper on the changes they would like to see downtown."

Might I remind you that most of those groups are a part of Auction Action Greensboro and the Greensboro Partnership and receive their funding from the same. In other words: who do you really think will be calling the shots? That's right, the same old white men who have been calling the shots all along.

"Mayor Robbie Perkins said he would create a council committee to work with young professionals on downtown issues."

Again, behind closed doors. More delay, obfuscation and manipulation.? ?

?We felt we wanted to have a seat at the table,? said Tim Tsujii, a co-chairman of synerG.

Group members are worried that Greensboro trails other cities in wages and high-paying jobs and in having such urban amenities as diverse retail or unique entertainment.

?This, paired with organizational obstinacy for changes and innovative/creative solutions, creates significant obstacles and impediments to the improvement of our downtown,? according to the white paper.

But representatives said their concerns are bigger than the issues with one organization. "

They're right, but they won't be in control of anything.

"They also asked the council to focus on ?large transformation projects? such as the proposed performing arts center and to invest in a center city small business incubator."

In that last quote you'll find the real agenda,? ?large transformation projects? that tax our working class neighborhoods and take jobs away from where we need them most. That being where the vast majority of Greensboro's residents live. Why are 2000 residents Downtown getting all the amenities while almost 270,000 residents throughout the rest of the city do without? Because Downtown is where Greensboro's elite decided to invest their personal fortunes. And if it's a business incubator you want, here's a proven method and it should be city wide and not just downtown.

"Other news from the Greensboro City Council meeting....

Council members agreed to sell about 7 acres south of Lee Street to the South Elm Development Group for $428,000 an acre. The development is expected to be worth at least $50 million.

The development group will act as a master developer on the site, working with other companies that want to build or own specific buildings in the redevelopment.

It?s unclear what will be built on the property. The developers would like to see a proposed downtown university district there. It likely will be a year or so before any construction begins."

So it's still unclear what will be built on the City owned property but it gets approval anyway. Could you or I build anything in Greensboro without first telling the City what it was we were going to build. Don't give me that crap about how it fits the Redevelopment Plan.?? As I pointed out last week, South Elm Street Redevelopment isn't even a legal entity in North Carolina. Oh wait, I'm wrong, like most things Greensboro they have 2 names: South Elm Development Group is a Durham company.

"The city provided the nonprofit with the loan to help it move to a new building. Nonprofit leaders said it does not yet have enough new tenants and may have to lay off staff if it must start repaying the loan.

Council members Nancy Vaughan, Marikay Abuzuaiter and Tony Wilkins voted against the decision. Vaughan questioned the center?s decision to rent space to a U.S. division of an Italian furniture company. She said the center should be rented to start-up companies."

I'd like to personally thank councilmembers Vaughan, Abuzuaiter and Wilkins for standing up against corporate welfare to foreign corporations. This is in-fact exactly what happens when non profits rent space designed for local start-ups to foreign competitors. The Nussbalm Center proved themselves incapable of managing their own business and were forced to violate their own rules and return to the taxpayers' well just like all of Greensboro's connected "non profits" too often do. This is another reason why we really don't want the powers that be to be in charge of yet another business incubator.

" The council removed from its agenda a possible contract to hire the Triad Real Estate and Building Industry Coalition to lobby on behalf of the city.

The council made no comment about why it made the decision. City Manager Denise Turner Roth later said the city still may consider hiring a lobbyist but it won?t be TREBIC."

I think I know why they didn't approve the plan. I think my previous blog posts and e-mails concerning the subject might have alerted them. (Not that I was the only one.) Again, this was/is no more than an another attempt at corporate welfare. Let TREBIC fight and fund it's own battles. The City of Greensboro already has plenty of favorable representation at the State level concerning the Jordan Lake Rules which, by the way, the City saw coming since the 1960s and never addressed. Sometimes we are forced to pay for our mistakes like it or not.? I commend the Council on putting it off and recommend you not hire any lobbyist to bend the Jordan Lake Rules. After all, it was Greensboro that created the problem in the first place, trying to legislate our way out of it only proves Greensboro to be as sinister and low as Billy Jones (that would be me) is constantly making it out to be.
