Researchers report more condom use among teenagers

WASHINGTON (AP) ? More high school students are using condoms than 20 years ago ? but progress has stalled with a lot of work still needed to protect young people from the AIDS virus, government researchers reported Tuesday.

Today, 4 of every 10 new HIV infections occur in people younger than 30, according to the Centers for Disease Control and Prevention ? and the teen years, just as youths become sexually active, are key for getting across the safe-sex message.

Using a long-standing survey of high school students' health, the CDC tracked how teen sexual behavior has changed over 20 years. The results are decidedly mixed.

About 60 percent of sexually active high school students say they used a condom the last time they had sex, researchers told the International AIDS Conference. That's an improvement from the 46 percent who were using condoms in 1991.

"This is good news," said Dr. Kevin Fenton, director of CDC's HIV prevention center. But, "we need to do a lot more."

The problem: Condom use reached a high of 63 percent back in 2003.

Black students are most likely to heed the safe-sex message, yet their condom use dropped from a high of 70 percent in 1999 to 65 percent last year, the study found.

If mom and dad get antsy about discussing condoms, well, about half of high school students have had sex, a proportion that hasn't changed much over the two decades, the CDC reported. Today, 47 percent say they've had sex, down just a bit from 54 percent in 1991. Again, black teens made the most progress, with 60 percent sexually active today compared with 82 percent two decades ago.

The more partners, the more risk. Fifteen percent of high school students say they've had four or more partners, down from 19 percent in 1991.

Fenton said part of the problem is that many school systems don't have strong enough sex education policies that include teaching teens about how to prevent HIV. But he cautioned that the CDC study can't link the abstinence-only policies pushed by Congress through the late 1990s and early 2000s to the stalled progress.

Overall, though, a characteristic of the young is to think they're invincible, Fenton added.

Lawrence Stallworth, 20, of Cleveland can attest that they're not. He learned he was infected with HIV at age 17, when he was a high-school senior, after a hospitalization. A black gay man, he's among one of the nation's highest-risk groups.

He's now an Ohio AIDS activist who works to teach young people that they need to protect themselves, and how.

"I want people to have the tools to keep themselves safe," said Stallworth, who at this week's AIDS conference is working with the nonprofit Advocates for Youth to increase young people's awareness of an epidemic that in the U.S., today gets little publicity.

Part of that involves our society getting "better at being more open about being able to talk about sex," Stallworth added. "It's still a taboo issue."

Indeed, at this week's conference, the world's largest AIDS meeting, young gay black men in the U.S. are emerging as a population in special danger from rising HIV infections.

Black gay and bisexual men account for 1 in 500 Americans but 1 in 4 new HIV infections. The odds that a black man who has sex becomes infected rise from 1 in 4 at age 25 to a stunning 60 percent by age 40, said Phill Wilson of the Black AIDS Institute.

But they're not the only ones at risk. The CDC recommends that everyone in the U.S. ages 13 to 65 be tested for HIV at least once. Those at increased risk ? such as people who have multiple sex partners or men who have sex with men ? should be tested more frequently, at least once a year.

In South Carolina, 18-year-old Quinandria Lee offers an example of the safe sex practices that CDC says more young people should adopt.

Lee was frustrated at her school's abstinence-only focus. She learned about both male and female condoms from the South Carolina Contraceptive Campaign, and last year her principal allowed her to teach her classmates about them. Condoms are the only contraceptive that also protect against HIV infection.

But Lee credits her mother's frank talk about sex with this key protective step: Lee persuaded her boyfriend to go with her to a clinic where both got a clean bill of health before they ever had sex. Still, they use a condom every time.

"It's hard," she said of that get-tested conversation. But "you can't be too sure."

Developers: Better secure your in-app purchase transactions with free Beeblex service

Developers, better secure your in-app purchase transactions with free Beeblex service

Following the recent App Store in-app purchase hack that worked as a man-in-the-middle attack to spoof iTunes, rip off vendors, and potentially harvest user data, developer Marco Tabini has launched a new, free Beeblex service to better the secure the process for everyone. Except for the hackers, of course. And that's the point.

Beeblex works by providing developers with a small library that can be easily integrated within their apps and, in a matter of minutes, be used to validate IAP receipts to determine their validity. The algorithm used to perform the validation uses asymmetric encryption to protect all data, and is designed to deter man-in-the-middle attacks and certificate spoofing. In addition, Beeblex keeps track of receipt identification tokens and reports duplicates to the app, helping reduce the incidence of unauthorized receipt reuse.

The upside is more secure transactions, and -- free. The only potential downside is downtime on Beeblex's end, though they've built mechanisms into their SDK to defer transactions in case of any loss of service, be it on their end or simply because a user loses data connection.

It's not, and is not being advertised as, a bulletproof solution, but it can and will make the apps using it a harder and perhaps less attractive target for hackers.

Samsung Galaxy S, II and III pitted against one another in DisplayMate shootout

Samsung Galaxy S, II and III pitted against one another in Display Mate shootout

Feeling nerdy? Good, because the folks at DisplayMate have put together quite the comparison of the three different AMOLED displays featured in the Samsung Galaxy S, II and III smartphones. While the study places an emphasis on quantitative measures -- and thus leaves more subjective qualities out of the discussion -- the comparison is nonetheless an insightful look into the progression of Samsung's AMOLED display technology. Curiously, some elements remain unchanged, such as color gamut, which is 138 percent of the sRGB standard across all displays and is to blame for images that appear over-saturated. In terms of color temperature, DisplayMate reveals that while Samsung is trending closer to a white of natural daylight, even the Galaxy S III -- which measures 7,900 K -- is still far too bluish in comparison to an ideal 6,500 K.

Believe it or not, but there's one area that DisplayMate suggests is subtly worsening over time, and that's light reflection. The issue is nearly moot, however, as the 5 percent reflectance of the Galaxy S III is but a small shift from the previous iterations, and what's more, this remains among the lowest reflectance in the industry. We'd be fools to try and summarize all of DisplayMate's findings, but if you're curious to learn more -- and we hope you are -- be sure to hit up the source link below.

Alarm Clock by doubleTwist for Android offers a few new ways to wake up

Alarm Clock by doubleTwist for Android makes waking up less sucky

Awhile back doubleTwist decided to dabble in something other than media sync and cooked up a simple alarm clock Android app. Fast forward a few months, and it's now featured prominently in Google Play, but what's so great about it? After all, there's only so much you can do with an alarm clock, right?

All of the core functions are there, such as repeating and multiple alarms, each with custom labels and user-picked sounds and volume. There are flip and analog-style faces with a low-brightness nightstand mode available, plus custom snooze durations and vibration toggles. Beyond that, things get a bit more interesting.

Instead of setting alarms for just any ol' time, doubleTwist's app offers ideal times to set alarms in line with common sleep cycle durations. That way, you can either figure out what time you should go to sleep if you want to get up for a certain hour, or what time would be best to wake up without messing with your natural rhythm.  Based on your location and the latest weather reports, the app can also figure out what time the sun is rising, if you're the type to go by Mother Nature's alarm clock.

APNewsBreak: Texas switches to 1-drug execution

(AP) ? Texas will use one drug to carry out executions instead of its usual three-drug method because it has run out of the second drug, prison officials said Tuesday.

The Texas Department of Criminal Justice will use just pentobarbital, the agency said in a Tuesday statement to The Associated Press. Pentobarbital is a sedative that is typically the first of three drugs administered.

The agency's stock of the second drug, pancuronium bromide, expired, and it was unable to obtain more, spokesman Jason Clark said.

Clark said other states also now use one drug and courts have upheld the procedure. Inmates in several states have challenged their executions on the basis of what drugs are used.

Texas is the nation's most active death penalty state. It has executed 482 people since the state reinstated capital punishment in 1982. Five people have been executed this year.

"Implementing the change in protocol at this time will ensure that the agency is able to fulfill its statutory responsibility for all executions currently scheduled," Clark said in the statement.

Texas' next execution is scheduled for July 18. Yokamon Hearn was convicted of the 1998 slaying of a 23-year-old stockbroker from Plano, north of Dallas.

Hearn's attorney, Richard Burr, said Tuesday that he was examining the change but had not decided whether to file any new motions over it.

Several states have had difficulty obtaining drugs to carry out executions. Texas prison officials said in May that the state had enough pentobarbital for 23 executions. No executions have taken place since then.

A 5-gram dose ? about 3.4 ounces ? is the first lethal drug used during each execution in Huntsville, according to Texas execution procedures.

Last year, one of the drugs Texas had used in the process, sodium thiopental, became unavailable when its European supplier bowed to pressure from death penalty opponents and stopped making it. No other vendor could be found, so the drug was replaced by pentobarbital, which is also used to put down animals.

Pancuronium bromide is a muscle relaxant typically used after pentobarbital. The final drug, potassium chloride, stops the heart.

Four other states ? Arizona, Idaho, Ohio and Washington ? have used a single drug to carry out executions, according to the Death Penalty Information Center. Ohio was the first to use just pentobarbital, for a March 2011 execution.

In April, an Arizona inmate shook for several seconds after receiving a lethal dose of pentobarbital. The drug was used by itself in that case.

Other states have switched to other drugs, including propofol, the anesthetic blamed for Michael Jackson's death, to do single-drug executions.

An inmate on Oklahoma's death row asked a federal court Tuesday to halt his execution because Oklahoma has just one dose of pentobarbital left. Michael Hooper is scheduled to be executed Aug. 14.
