Internet porn means birds 'n' bees talk comes earlier, says expert

A boy works on a laptop.

A father recently sat down to have "the talk" with his 10-year-old son. After he got through the basics on the birds and the bees, the boy asked, "Why do men wear masks when they're having sex?"

Though the father said he had parental controls engaged on his iPad, the son managed to find a fetish site depicting men in masks.

As the anecdote told by sex educator Cindy Gallop so plainly illustrates, kids look at porn. Kids look at porn on the Internet. And yes, let's go further: Your kids look at porn on the Internet. Gross? Probably, yes. But it's reality.

Keeping your kids from Internet porn is practically impossible, experts agree. Whether kids under 18 deliberately searched out sexually explicit sites, or stumbled upon them accidentally, approximately 40 percent see Internet porn every year, the study found. And yes, all that exposure does leave a mark: "Although research is scarce, investigators see links between young people who access Web porn and unhealthy attitudes toward sex," the American Psychological Association noted in 2007.

But parents don't have to be powerless. Explaining to your kids that difference between pornography and what goes on between consenting adults in real life is key, say some sex educators. You won't want to do it. Your kid won't want to hear it. And unfortunately, because of the Internet, that conversation has to come sooner rather than later. But it may make all the difference to kids when they're grown.

"This is not because 8-year-olds go looking for porn, it's a function of what they're shown on someone's cellphone on the playground, what happens when they go out to the neighbor's house," said Gallop, a fervent proponent of reality-based sex education. Preparing kids for a healthy sex life as adults was part of her message Saturday at "The Future of Porn" talk at South by Southwest Interactive in Austin.

Gallop is CEO and founder of Make Love Not Porn, a website dedicated to correcting sexual misconceptions picked up by viewers of professional for-profit pornography. The Internet venture does this, in part, by curating videos of "real sex" uploaded to the platform by "real people" ? not "porn stars." (Obviously, the video portion of the website is for adults only.) But as Gallop emphasized, the misconceptions picked up through pornography can start at a very young age.

"It doesn't matter what parental controls you put in place, kids live their lives in other places ... or an 8-year-old does something really cute and innocent. They discover a new naughty word and they Google it." Next thing you know, Gallop pointed out, that curious boy or girl is one or two clicks away from something he or she is too young to understand.

The exposure may result in relationships that lack scope and communication. "Too many young people start their sexual careers attempting to duplicate porn, not realizing that this model lacks so much," noted sex educator and author Dr. Marty Klein recently wrote in the Huffington Post.

"With valuable face-to-face communication increasingly replaced by brief digital syllables ... young adults' ability to simply talk about what goes on in bed ... is lagging further and further behind the needs of their sexual encounters ? whether hookup or more intimate."

Kids don't want to hear a lot of things. They don't want to hear that they shouldn't drive too fast or date the mean hot person or eat fast food all the time. But if the Internet is going to put your kids in the path of a virtual tsunami of porn, the least you can do is warn them about it.

Therapies for ALL and AML targeting MER receptor hold promise of more effect with less side-effect

Therapies for ALL and AML targeting MER receptor hold promise of more effect with less side-effect

Monday, March 11, 2013

Two University of Colorado Cancer Center studies show that the protein receptor Mer is overexpressed in many leukemias, and that inhibition of this Mer receptor results in the death of leukemia cells ? without affecting surrounding, healthy cells.

The first study, published today in the journal Oncogene, worked with acute myeloid leukemia (AML), for which current chemotherapies offer a cure rate of only about 55 percent.

"In about 2/3 of all AML patients and about 90 percent of adult AML patients, we found that the Mer receptor was upregulated. Mer receptor protein shouldn't exist in normal myeloid cells, but we found it abnormally expressed," says Doug Graham, MD, PhD, investigator at the CU Cancer Center and associate professor of pediatrics and immunology at the University of Colorado School of Medicine.

The Mer receptor sits within the cell membrane, and when it becomes activated the cell receives signals to grow and survive. Leukemia and perhaps many solid cancers have taken advantage of Mer's cell survival function to assist the cancer's rampant proliferation. When Graham and colleagues used shRNA to silence the production of Mer in leukemia cells, they showed decreased leukemia cell survival, increased sensitivity to existing chemotherapies and longer survival in mouse models of leukemia.

A second study, published this month in Blood Cancer Journal, shows similar results with acute lymphoblastic leukemia (ALL), the most common pediatric cancer.

"The ALL cure rate is already over 80 percent, but for patients who relapse, the prognosis is much less optimistic. We need targeted therapies to use as second-line treatments for the population for whom existing therapies aren't lasting, particularly in patients with relapsed T cell ALL," Graham says.

Second, he points out that a quarter of pediatric ALL patients who respond to existing chemotherapies do so at the price of significant long-term side-effects. "And so in addition to increased survival, the second goal of targeted therapies is decreased side-effects," Graham says.

Inhibition of the Mer protein receptor is promising on both accounts.

"Not only do B-cell and T-cell leukemia cells die when you knock down Mer receptor expression, but these cells are also much more sensitive to existing chemotherapies. By hitting Mer, we're making the chemotherapy more effective," Graham says.

In ALL and AML, Graham's studies show that making Mer inhibition means that less chemotherapy may have equal or stronger effect. Strong preliminary evidence shows that Mer may be the key to less toxic, more effective therapies for leukemia.

Samsung's latest Galaxy S IV teaser shows the outline of... a phone

Samsung's latest Galaxy S IV teaser the rough outline of what appears to be a phone

Pause for your latest Galaxy S IV news break ahead of the March 14th unveiling: Samsung's Mobile US Twitter account has posted this picture showing what appears to be a smartphone (shocker!) -- that matches our existing Galaxy S III 1:1 minus the earpiece and with a slightly shifted logo FWIW -- shrouded in shadow. We'll understand if you've been overtaken by awe and need a moment, Jeremy certainly seemed impressed.

Curiosity sleeps as solar blast races toward Mars

(AP) ? Curiosity hunkered down after the sun unleashed a blast that raced toward Mars.

While the hardy rover was designed to withstand punishing space weather, its handlers decided to power it down as a precaution since it suffered a recent computer problem.

"We're being more careful," project manager Richard Cook of the NASA Jet Propulsion Laboratory said Wednesday.

While Curiosity slept, the Opportunity rover and two NASA spacecraft circling overhead carried on with normal activities.

On Tuesday, scientists noticed a huge flare erupting from the sun that hurled a stream of radiation in Mars' direction. The solar burst also spawned a cloud of superheated gas that barreled toward the red planet at 2 million mph.

The eruption did not appear severe or extreme, but "middle of the road, all things considered" said space weather chief Bob Rutledge at the National Oceanic and Atmospheric Administration.

The solar tempest was not expected to have an impact on Earth. In the past, such outbursts have triggered solar storms with the ability to disrupt utility grids, airline flights, satellite networks and GPS services. They're also known to produce shimmering auroras in places farther from the poles.

Since Mars lacks a planet-wide magnetic field, it does not experience geomagnetic storms. Rather, the planet sees a spike in radiation, Rutledge said.

Powerful solar blasts can cause trouble to Mars spacecraft. In 2003, an intense solar flare knocked out the radiation detector on the Odyssey orbiter.

NASA does not expect similar drama from the latest solar activity.

In the worst-case scenario, one or more of the working Mars spacecraft may enter "safe mode" in which science activities are halted but they remain in contact with Earth.

"We'll be watching and seeing what happens," said Roger Gibbs, JPL deputy manager for the Mars exploration program.

The unsettled space weather comes as Curiosity is recovering from a memory hiccup that put its science experiments on hold. It was the first major problem to hit the car-size rover since it landed last year in an ancient crater near the Martian equator to hunt for the chemical building blocks of life.

Engineers were in the middle of troubleshooting when they decided to wait for the weather to pass. The delay means it'll take longer for Curiosity to return to analyzing the pinch of rock powder it collected from a recent drilling.

Since its instruments are turned off, it can't use its radiation sensor to track the solar particles.

"It's just bad timing," Cook said.

Illinois GOP didn't have votes to oust chairman

CHICAGO (AP) ? A member of the Illinois Republican Party's central committee says a meeting was canceled partly because there weren't enough votes to fire party chairman Pat Brady.

Some committeemen wanted to oust Brady, largely because he publicly supported a bill to legalize gay marriage earlier this year.

A meeting had been scheduled for Saturday. It was canceled Friday night amid pressure from prominent Republicans, including U.S. Sen. Mark Kirk and House Republican Leader Tom Cross.

State Sen. Dave Syverson is a committeeman and GOP treasurer from Rockford. He says the vote would have been close, but members who had concerns about Brady separate from his gay marriage stance "didn't want to be tied up in" that flap.

A spokesman for Kirk says he's pleased and "it's time to move on."
