HIV increase among county’s young black men prompts CDC to focus on prevention

Friday, February 4th, 2011

A startling increase in the number of reported HIV infections among young black men in Milwaukee County who have sex with men may be linked to several risk factors, including internalized homophobia and living on the streets, according to a joint investigation by local, state and federal health officials released Thursday.

The investigation began after the Wisconsin Division of Public Health noted a 144% increase in reported HIV diagnoses in Milwaukee County from 2000 to 2008 among black men ages 15 to 29 who have sex with men.

The resulting investigation – which involved the state, Milwaukee Health Department and U.S. Centers for Disease Control and Prevention – found the increase likely wasn’t due to intensified testing efforts, but to increased transmission of HIV through high risk behavior and nondisclosure of HIV status.

If the spike in HIV diagnoses among young black men isn’t reversed, the entire metro area could see increased rates, Milwaukee Health Commissioner Bevan Baker warned Thursday.

A higher percentage of young black males than nonblack males have male sex partners at least five years older, according to the investigation, which involved a sampling of Milwaukee County men with HIV or syphilis diagnoses. Older men are more likely to be infected with HIV.

The Milwaukee Health Department last summer announced a multifaceted strategy to boost HIV testing, reduce stigma in the community and teach men to protect themselves.

The city partnered with Diverse & Resilient, an organization that works to improve the public health of lesbian, gay, transgender and bisexual individuals. That group networked with multiple other community groups and the medical community. It has trained 60 men to help provide information to the targeted population. (more…)

NASA’s Week of Surprises for Shuttle Crew

Sunday, January 16th, 2011

First the Wife of Endeavour Commander Mark Kelly Is Shot, Then a Crew Member Has Bike Accident

The events of the last two Saturdays have stunned NASA in a way the space agency could never anticipated.

Mark Kelly, Endeavour’s commander for the space shuttle mission in April, found himself on the way to Arizona where his wife, Rep, Gabrielle Giffords, was critically injured in a shooting. Kelly, at his wife’s bedside while she fights for recovery, asked NASA to name a backup commander, Rick Sturckow, for Kelly’s mission.

This past weekend, astronaut Tim Kopra was injured during a bicycle ride. The extent of his injuries has not been released, but they are serious enough to have mission managers scrambling to consider who could take his place on the STS 133 mission, Discovery’s oft-delayed final flight, which is tentatively scheduled to launch next month.

NASA’s choices: Wait for Kopra to heal from his injuries, or replace him on the mission. Kopra has been training for his two spacewalks for well over a year — his mission was originally scheduled to fly in September 2010 and it was once the last space shuttle flight before the fleet was retired.

Astronauts give up anything risky when they start training for a flight — no car racing, no sky diving, no scuba diving, no mountain climbing. Drew Feustel, who flew on the last mission to repair the Hubble Space Telescope, had to indulge his love for fast cars on the sidelines, watching his sons’ race. Scott Parazynksi climbed Mount Everest only after he retired from the astronaut corps. (more…)

Scientist Plans to Clone Woolly Mammoth

Sunday, January 16th, 2011

Scientist Plans to Clone Woolly Mammoth (Just Not For Theme Park)

Get your Jurassic Park and Lord of the Rings: Return of the King jokes ready. A professor at Japan’s Kyoto University is claiming that he’ll be able to resurrect a woolly mammoth within roughly four years’ time, bringing new life to a species that died out more than 5,000 years prior.

Even though Dr. Akira Iritani isn’t going to attempt to duplicate DNA strains from animals trapped in amber, the technique he’s propositioning—which was already used by Dr. Teruhiko Wakayama of the Riken Centre for Developmental Biology to clone a mouse previously frozen for sixteen years—does sound fairly close to that on paper.

Iritani intends to travel up to a Russian mammoth research laboratory this summer in order to acquire the correct tissue from a frozen mammoth. If he can uncover a working sample of at least three square centimeters, he’ll claims that he’ll be able to insert the nuclei of the frozen mammoth cells into the egg cells of an African elephant. Following a 600-day gestation period, out pops a new woolly mammoth—in theory.

“Now that the technical problems have been overcome, all we need is a good sample of soft tissue from a frozen mammoth,” said Iritani in an interview with the Daily Telegraph. (more…)

Down’s syndrome DNA blood test ‘better screening offer’

Thursday, January 13th, 2011

A DNA blood test for Down’s syndrome could save nearly all pregnant women from invasive tests like amniocentesis, say experts.

Invasive testing takes place in 3% to 5% of pregnant women in the UK – some 30,000 women – and increases the risk of miscarriage.

The new DNA blood test could bring this down to 0.1%, according to a study in the British Medical Journal.

Around one woman in every 100 who has an invasive test will miscarry.

Some faced with the dilemma choose not to go for a diagnostic test – which involves having a needle inserted into their bump to draw off a sample of placenta cells or some of the fluid that bathes the baby – particularly if their estimated risk of having a child with Down’s syndrome is smaller than the chance of miscarriage.

The non-invasive DNA blood test could offer another option. (more…)

NASA trumpets rocky exoplanet find

Tuesday, January 11th, 2011

Kepler-10b is ‘planetary missing link’

NASA has announced it’s nailed the first “bone-fide” [sic] rocky exoplanet, which at 1.4 times the diameter of Earth is the smallest such body spotted to date outside our solar system.

As its name suggests, Kepler-10b was identified orbiting star Kepler-10 – at a distance of 560 light years from Earth – by the agency’s habitable planet-seeking Kepler mission.

Between May 2009 and January 2010, the spacecraft identified a list of stars as potential hosts of small planets. Its photometer clocked the miniscule drops in light as a body transited Kepler-10, enabling atronomers to calculate the potential planet’s size, orbital period and distance from the star.

Further work by the WM Keck Observatory 10-meter telescope in Hawaii, specifically measuring “tiny changes in the star’s spectrum, called Doppler shifts, caused by the telltale tug exerted by the orbiting planet on the star”, allowed scientists to announce a confirmed find.

Kepler-10b orbits every 0.84 days, has a mass 4.6 times that of Earth, and a density of 8.8 grams per cubic centimeter, or “similar to that of an iron dumbbell”, as NASA nicely puts it.

Google Launches Worldwide Science Fair

Tuesday, January 11th, 2011

Google has launched an online science fair, allowing any student with an Internet connection and a Google account to take part in the competitive event.

“You may have participated in local or regional science fairs where you had to be in the same physical space to compete with kids in your area. Now any student with an idea can participate from anywhere, and share their idea with the world,” Google wrote in a blog post.

The Google Global Science Fair 2011 is open to students aged 13-18 years old, working solo or in groups of up to three. Applicants should come up with their own hypothesis, create an experiment to test it, and present the results and conclusion in either a two-minute video or a 20-slide presentation. Current entries from offline local science fairs will also be accepted when embedded into Google’s application. Registration is open through April 4, 2011.

In partnership with the European Centre for Nuclear Research (CERN), the LEGO Group, National Geographic and Scientific American, Google is awarding 12 prizes, including the grand prize of a 10-day trip to the Galapagos with National Geographic Explorer and a Google scholarship worth $50,000. Select winners will also receive internship opportunities with the sponsors. (more…)

Verizon website downtime reminiscent of AT&T iPhone preorder troubles

Tuesday, January 11th, 2011

Strong interest in the newly announced Verizon iPhone appears to have caused intermittent outages on the Verizon website Tuesday, resembling AT&T’s iPhone 4 preorder woes from last year.

Scattered reports of downtime on the Verizon Wireless website seem to indicate that pent up demand for the Verizon iPhone has overwhelmed the carrier’s servers at times throughout the day.

According to one AppleInsider reader, attempts to access the upgrade section of Verizon’s website timed out or received the message: “Safari can’t open the page because the server unexpectedly dropped the connection. This sometimes occurs when the server is busy. Wait for a few minutes, and then try again.”

Several other readers have also reported being unable to access the Verizon website on Tuesday.

Verizon announced the much-rumored and long-awaited CDMA iPhone earlier Tuesday at a press event in New York City. (more…)

CES 2011: Five Essential Trends

Sunday, January 9th, 2011

What a difference a year makes. Last year’s CES was remarkable mostly for its complete lack of remarkableness. I have trouble remembering a single product I saw and everyone seemed depressed. The mood at CES 2011 was akin to the vibe in a locker room on game day or backstage at a big performance: Excited, energized and maybe a bit edgy.

I wondered if it was just me who noticed this, so I asked the best judge of the mood in Vegas: a local cab driver.

“The mood is totally different this year. People are upbeat,” my driver told me. He said that he could tell there were a lot more attendees at this year’s CES, and they just seemed happier.

The feeling on the convention floor was the same: electric. Mobile analyst Sascha Segan noted that virtually none of the major products unveiled at this year’s CES had pricing info. I told him that’s actually a good thing. It means vendors are showing us stuff early, taking the risk of unveiling unfinished products, marketing plans and ideas. I love that.

Overall the show was, well, overwhelming, but in a good way. Alongside the finished and polished products were prototype and experiments. Sony devoted an entire area to the future of 3D – most of it did not need glasses and looked very cool. There were wacky designs like the Lady Gaga Polaroid product line and a general sense of fun on the show floor. There we’re also trends.

1.Tablets

With 75 tablets introduced at CES 2011, I was right to label this year’s show tabletpalooza. There were lots of Android tablets and the most popular size was 10.1 inches. I have to admit I do not like these somewhat long and thin devices compared to the Apple iPad’s 4:3 aspect ratio, but I’m sure I could grow used to it. The tablets look alike and feel alike. They all have multiple cameras, HD or near HD screens, some have slightly rubberized backs, and others more polish. Virtually all are black.

We named the Motorola Xoom the best tablet of the show. It’s the first to show off Android 3.0 (also known as Honeycomb). Unfortunately, the on-the-floor demo was simply a video of the interface. On the other hand, you could walk over to the RIM booth and try the Blackberry Playbook’s zippy QNX interface for yourself. As I’ve said before, I like what I’ve seen of the Playbook, even the 7-inch screen size feels right—and I’m not typically a fan of that form factor.

That said, I get why everyone is so excited about the Xoom. Most manufacturers I talk to that are building Android tablets (which is like everyone) won’t ship until Google releases Honeycomb. That should happen in the spring. Even from the video I can see that the interface has been completely redone for the larger tablet screen. Xoom deserves the nod as the best tablet of the show because of the stunning hardware and incredible promise of Android 3.0, and it’s the tablet I’m most anxious to see later this year.

2.Super Phones

I did not expect to see so many new phones at CES (seriously, what will anyone have left for Mobile World Congress in Barcelona next month?). The emergence of the Super Phone was not entirely surprising, but I do like the branding. It’s better than calling these really powerful cell phones “Tiny Computers.”

Super Phones, which all look virtually identical, are characterized by their Tegra 2 CPUs, high-resolutino screens, 4G connectivity, and plethora of output ports, including HDMI out so you can play Angry Birds on your HDTV—at full 1080p resolution, no less.

Amidst these handhelds was the fascinating Motorola Atrix. Remember the Redfly, a small, red, super-thin dummy laptop that hooked up to your phone to give it a large screen and keyboard (and nothing else)? Well this is that, but done in a way that makes a lot more sense. You get a very sexy and slim, roughly 13-inch phone charger and super phone dock that also sports its own LED screen, full-sized keyboard, and Webtop App, which acts as sort of a super-light, wrap-around OS. The phone is still powering everything, but you can run a handful of apps, including the Firefox web browser, on the specialized desktop interface, while having large-screen access to every single feature of your tiny comp…er…Atrix Super Phone. You can even run virtualized desktop client apps through it. In other words, you may never need a real desktop or laptop for your office again. People fell in love with this product at the show; I spent some time with it and agree it shows tremendous promise. (more…)

Exercise Cuts Prostate Cancer Death Risk

3 Hours of Vigorous Activity a Week Associated With a 61% Lower Risk of Prostate Cancer-Specific Death, Researchers Say

Men diagnosed with prostate cancer may be able to reduce their risk of death not just from prostate cancer but from any cause by exercising vigorously for at least three hours per week, new research indicates.

A study performed by researchers at the Harvard School of Public Health and the University of California-San Francisco examined the records of 2,705 men who had been diagnosed with nonmetastatic prostate cancer over an 18-year period in a project known as the Health Professionals Follow-Up Study. The men in the study reported the time they spent exercising on a weekly basis. This included running, bicycling, walking, swimming, other sports, and even outdoor work.

Non-vigorous and vigorous activity proved beneficial for overall survival, the study says.

Men who walked less than 90 minutes per week at a normal to brisk pace had a 46% lower risk of dying from any cause compared to men who walked less than 90 minutes per week.

Men who reported vigorous activity for at least three hours per week had a 61% lower risk of a prostate cancer-specific death, compared with men who exercised for less than an hour per week. (more…)

DNA analysis confirms body as that of slain NIU student Keller

Friday, January 7th, 2011

The family of 18-year-old Antinette “Toni” Keller knew in their hearts that the charred body authorities discovered in a park last year near Northern Illinois University was hers, even before DNA testing confirmed it.

“This definitely makes the reality more tangible and vivid,” said Mary Tarling, Keller’s cousin and a spokeswoman representing Keller’s family.

Prosecutors in DeKalb County said Thursday at a brief hearing in DeKalb County Circuit Court that DNA analysis confirmed the body was that of Keller, an NIU art student from Plainfield.

A fragment of thighbone was sent to Dallas-based laboratory Orchid Cellmark several weeks ago to compare it with saliva samples from Keller’s mother and father, DeKalb County State’s Attorney Clay Campbell said.

Keller disappeared Oct. 14. A body believed to be hers was discovered Oct. 16, but positive identification had not been made.

William Curl, who is charged with murder, sexual assault and arson in Keller’s death, is being held on about $5 million bail. He appeared in court Thursday via video.

A forensic anthropologist is testing the charred remains.

Attorneys will reconvene in court Feb. 17.
