STDs rife among US teenage girls March 11, 2008

Human papillomavirus, HPV

HPV, which can cause cancer, was found to be the most common STD

One in four teenage girls in the United States has a sexually-transmitted disease, a study has indicated. The study, by the federal Centers for Disease Control and Prevention (CDC), found an even higher prevalence of STDs among black girls.

Researchers analysed data from a nationally representative sample of 838 US girls aged 14 to 19.

A virus that causes cervical cancer - HPV - was the most common, followed by chlamydia, trichomoniasis and herpes.

The CDC says the study is the first in its kind to examine the prevalence of common sexually transmitted diseases among adolescent girls.

It found that nearly half of the African-American girls surveyed had at least one STD, while the rate was 20% among white and Mexican-American teenagers.

Human papillomavirus, or HPV, affected 18% of the girls surveyed, chlamydia 4%, trichomoniasis 2.5%, and herpes simplex virus 2%.

Screening recommended

The CDC’s Devin Fenton said it was a serious issue because the diseases could lead to infertility and cervical cancer.

“Screening, vaccination and other prevention strategies for sexually active women are among our highest public health priorities,” he said.

The CDC is recommending annual chlamydia screening for all sexually active women under 25, and HPV vaccines for girls aged 11 to 12, followed by booster injections.

John Douglas, the CDC’s head of STD prevention, says screenings are underused because teenagers often do not think they are at risk.

Analysts say some doctors are also reluctant to discuss screening with teenage patients because of confidentiality concerns, knowing parents would have to be told of the results.

 

Lunar Eclipse March 2, 2008

Credit & Copyright: Alex Mukensnable Explanation: Just opposite the setting Sun, the already-eclipsed Moon rose over the Hawaiian Islands on February 20. A view near the 14,000 foot peak of volcanic Mauna Kea on the Big Island, a popular spot for astronomers, offered this remarkable play of shadows and sunlight. With snowy cinder cones in the foreground, the Moon lies within the shadow cast by the mountain — a shadow extending across a lower cloud deck and on through Earth’s dense atmosphere. As the lunar eclipse is drawing to a close, the curved shadow of the limb of planet Earth itself can also be traced across the Moon’s surface, some 400,000 kilometers away.

Amazing moment the world’s biggest Christ was struck by lightning

This was the dramatic scene as the world’s largest statue of Jesus was hit by lightning. The bolt parted the thunderclouds over Rio de Janeiro, Brazil, to strike Christ the Redeemer.

The statue is 130ft tall, is made of 700 tons of reinforced concrete and stands atop the 2,296ft Corcovado mountain overlooking the city.

It was named one of the new Seven Wonders of the World in 2007.

Sunday’s storm caused havoc in Rio, felling trees in several neighbourhoods - but did not damage the statue.

Brave New World Convinced Bush December 28, 2007

Aldous Huxley’s ‘Brave New World’ Convinced Bush To Ban Embryonic Stem Cell Research

bushvetoesem.jpg Shortly after taking office, President Bush announced a policy allowing federal funding of research only on existing stem cell lines, despite the urging of several of his advisers and the scientific community for expanded funding. Bush has nevertheless remained stubborn, twice vetoing legislation that would have lifted the restrictions.

In a new piece in Commentary magazine, Jay Lefkowitz — who advised Bush on stem cells — reveals how the President formulated his 2001 policy. While Bush heard from a variety of groups on both sides of the issue, the turning point appeared to come when Lefkowitz read from Aldous Huxley’s fictional novel, Brave New World, and scared Bush:

A few days later, I brought into the Oval Office my copy of Brave New World, Aldous Huxley’s 1932 anti-utopian novel, and as I read passages aloud imagining a future in which humans would be bred in hatcheries, a chill came over the room.

“We’re tinkering with the boundaries of life here,” Bush said when I finished. “We’re on the edge of a cliff. And if we take a step off the cliff, there’s no going back. Perhaps we should only take one step at a time.”

It’s unclear what passage Lefkowitz read, but Brave New World opens with a scene at the Central London Hatchery and Conditioning Centre, where embryos are turned into full human beings — often dozens of pairs of “identical twins” to ensure “social stability.”

Scientists are not proposing such fictional experiments and recognize the need to balance ethics with scientific progress. In fact, the legislation expanding embryonic stem cell research (vetoed by Bush) — actually proposed ethics regulations that were stricter than Bush’s. Additionally, a bill banning human cloning was blocked by conservatives in Congress in June.

Six years since the President’s misguided, outdated restrictions, the scientific community has come together in support of lifting this ban. Even University of Wisconsin Professor James Thomson, whose work isolating embryonic stem cells has been used by the right wing — including Lefkowitz — as vindication for Bush’s policies, has stressed that the administration’s restrictive stem cell policies are “counter to both scientific and public opinion” and are inhibiting potential treatments.
