Dangerous Human Experimentation

1 Campus Facebook Blackout: Unethical Human Research

Harrisburg University of Science and Technology provost Eric Darr wondered if students and faculty could cope without Facebook, Twitter, MySpace, and AOL Instant Messenger, so he decided to block them, as well as the campus collaborative network, for one week. But even before the blackout starts some claim that it constitutes an experiment that requires approval from the school's institutional review board for human subjects research. "This sounds unethical.... How one can justify cutting off important communication media without ... consent," asks Ph.D. candidate Kevin Guidry. "What human subjects board would allow this type of surprise experimenting?," echos a university librarian, adding that students may "miss ... their medication-taking reminders [from] Facebook."

Time to Quit the Habit

2 One in Five Americans Still Smoke

After 40 years of declining smoking rates, the Centers for Disease Control and Prevention finds that one in five Americans smokes and this statistic has been stable for the past five years, says the LA Times. Smoking, the leading cause of preventable deaths in the US, kills about 446,000 Americans annually. West Virginia and Kentucky have the highest rate of smokers with about 26 percent of adults puffing regularly. California and Utah, with 13 and 10 percent of residents who smoke, report the lowest national rates. Smoking is not an equal opportunity habit. While six percent of college graduates smoke, almost 50 percent of GED holders and 25 percent of those who didn’t graduate high school smoke regularly. In addition, 31 percent of people living below the poverty level smoke.

Improvements After First Year

3 Both Parents at Risk for Depression

Both moms and dads have a greater risk for depression in the first year after a child's birth, but the risk also remains elevated into the child’s adolescence, say British researchers. The study followed almost 87,000 families in the United Kingdom, reports New York Times. In all, 39 percent of mothers and 21 percent of fathers in the study experienced depression within the child's first 12 years. Researchers found that the mother's risk for depression dropped by half after the first year, while fathers had only 25 percent of the risk faced by new dads. The findings, published in The Archives of Pediatrics and Adolescent Medicine, reveal that depression risk remained elevated compared to the general population until the child reached 12 years, when data collection for the study ended.

Grow What You Can't Reattach

4 Woman Regrows Tip of Pinky Finger

"Great success story, but gory: She kept the tip of her finger?!"
- Bianca in the comments

Deepa Kulkarni didn't want to leave the tip of her pinky finger behind, but when doctors said it couldn't be reattached, Kulkarni discovered a new procedure known as tissue regeneration, reports CNN. An accident involving a door left the woman without the tip of her right pinky finger, but she kept it in the freezer hoping to find a doctor who would help her. While Kulkarni couldn't find a doctor to reattach her fingertip, she did learn about a new procedure called tissue regeneration that gave her hope for a full fingertip once again. Kulkarni couldn't find a doctor near her that used tissue regeneration, so she educated a doctor with her research and persuaded him to try the procedure on her. It worked! Kulkarni still keeps the tip of pinky finger in her freezer though.

Blood Tests Prove Benefits

5 Massage Can Boost Immune System

A single Swedish massage, which is more vigorous than a lighter touch massage, may give a boost to your immune system, say researchers from Cedars-Sinai Medical Center. After a 45-minute Swedish massage, study participants experienced an increase in lymphocytes, which aid the immune system, reports Chicago Tribune. Blood samples taken before the massage and up to an hour after also showed that the individuals in the Swedish massage group, all of whom were healthy, experienced notable decreases in a hormone that can contribute to aggressive behavior, arginine vasopressin. In addition, participants receiving the Swedish massage also had small decreases in the stress hormone cortisol.

Surpassing Braille

6 Blind Can Listen to Playboy Image Descriptions

Some blind people don't have to settle for just the text-only Braille edition when it comes to Playboy magazine, says MSNBC. Houston-based Taping For The Blind, Inc. recruits volunteers who tape detailed descriptions of magazines for the blind. Suzy Hanks, who reads the news for a classic rock station, volunteers to describe the women in Playboy images. MSNBC notes that Suzy describes the images "without innuendo." An example of one of Suzy's descriptions from MSNBC follows: "Latina, brunette with dark chocolate brown eyes. She has long curly brown hair." Blind listeners tune into the readings at no cost through special radios that pick up the signal. Around 3,000 people subscribe to the service to hear descriptions of tabloids, newsweeklies and other periodicals.

Vaccinate Thyself

7 Patch Would Allow for Self-Vaccination

Researchers vaccinated mice against H5N1 using virus-like particles (VLPs) with the newly developed microneedle vaccine patch and found that the protective immunity they induced was equal to or greater than the immunity from the standard intramuscular injection that has to be given by a trained individual. An individual could vaccinate him or herself with the microneedle vaccine, which researchers see as the best approach during a pandemic. The VLPs induce a long-lasting immunity without causing disease and the skin has an excellent immune system that makes the patch an ideal method of vaccination. The seasonal flu hospitalizes over 200,000 and kills 36,000 in the United States every year, and pandemic strains continue to arise.

Double Attack on Sperm

8 Smoking May Damage Sperm in Men and Male Embryos

Two studies show that smoking can harm sperm in men who smoke and in male embryos from women who smoke while pregnant. In one study, 53 heavy smokers and 63 nonsmoking men had levels of protamines in their sperm analyzed. Protamines are key in sperm development and start the process that forms and packages chromosomes that contain DNA. Protamine levels in the sperm of men who smoked were 14 percent lower compared to the sperm of non-smokers. Oxidative stress related to smoking increased DNA damaged in the smokers' sperm. Another study found the number of germ cells in the testes of 24 male embryos between 37 and 68 days after conception were 55 percent lower from women who smoked compared to those from women who never smoked. Previous research revealed similar results in female embryos.

Tumor Biology Provides Insight

9 Biopsies Before and After Drug Measure Success

Finding the most effective dose for an experimental melanoma pill may be guided by biopsies taken before and after treatment, according to Plexxikon, the company that developed PLX4032. The drug blocks the mutated protein BRAF, found in 50 to 60 melanoma patients, from allowing the tumor to grow. Resistance does develop and analyzing the biopsies will help researchers understand how the drug is working. It will also help in developing more effective drugs. Gideon Bollag of Plexxikon said, "Looking at the biopsies from patients before treatment and two weeks after, we show we can inhibit the target directly in the tumor." Another drug developed by Roche, GDC-0973, is going to be combined with PLX4032 in hopes of prolonging its effects.
