Stressed Fit to Kill

1 Anxiety Can Hasten Aging, Shorten Lifespan

According to a study conducted by researchers at Brigham and Women's Hospital, a teaching affiliate of Harvard in Boston, a common form of psychological stress known as phobic anxiety may speed up the human aging process and contribute to serious diseases. The link is through telomeres, which protect chromosomes and prolong their effectiveness. Shortened telomeres are associated with accelerated aging and death, and with heart disease, cancer, and dementia. In the hospital's study of 5,243 women aged 42 to 69, those who manifested a high phobic anxiety level had telomeres shorter than unstressed peers by an average difference in length that translates biologically to six years of life. Researchers caution that whether anxiety causes short telomeres or vice-versa is still unclear.

Terrorism Not Suspected

2 Needles Found in Sandwiches on Delta Flights

Needles were found in turkey sandwiches aboard Delta Air Lines flights from Amsterdam to the US. The FBI is investigating, according to reports that say sewing needles were found in 5 sandwiches, injuring one passenger. The sandwiches were made in Amsterdam by catering company Gate Gourmet which handles meals for more than 3 million airline flights/year. After the needles were found, other Delta flights were notified and flight attendants stopped serving the sandwiches. The company is treating this as a criminal case and terrorism is not suspected, say Dutch authorities. "Delta has taken immediate action with our in-flight caterer at Amsterdam to ensure the safety and quality of the food we provide onboard our aircraft," the airline said in a written statement.

Qsymia May Be Available First

3 Comparing Belviq and Qsymia Diet Drugs

Belviq and Qsymia (formerly known as Qnexa) may be the first new weight loss drugs approved in years, but they're very different drugs, reports WebMD. While Belviq works with serotonin switches in the brain and may end up as a controlled substance due to the possibly of abuse as a hallucinogenic drug, Qsymia (phentermine and topiramate) works by suppressing appetite, increasing the feeling of fullness and making food taste less appealing. Since the DEA will rule on how to schedule Belviq, it may not be available until early 2013. Qsymia will be available around September 2012. Both drugs are approved for obesity, and for treating overweight patients with a BMI of 27 or more and a health condition caused by weight, such as diabetes or high cholesterol.

And Why Qnexa Name Nixed

4 How to Say Belviq and Qsymia

New drug names can be a challenge to pronounce, and Belviq and Qsymia (phentermine and topiramate) are no exceptions. The two new weight loss drugs were approved this summer by the FDA, and are not yet available. According to Vivus Pharmaceuticals, Qsymia is pronounced kyoo-sim-EE-uh. WebMD reports that Vivus preferred the drug name Qnexa, but the FDA thought it sounded too much like other drug names. Women taking Qsymia must also use birth control, and the drug will only be available from "certified pharmacies." Arena Pharmaceuticals says that Belviq is pronounced bel-VEEK. Belviq, which works by increasing levels of serotonin, may be classified as a controlled substance by the DEA.

Fast Food and Marriage Don't Mix

5 Chick-fil-a Is Opposed to Gay Marriage

Chick-fil-A, a fast-food chain with 1,600 locations, is at the center of a social storm, reports CNN. The company President Dan Cathy told Baptist Press that they are "guilty as charged" in their support of traditional family instead of gay marriage. CNN reports that Chick-fil-A is a top Google trend today, and Chick-fil-A's Facebook page and Twitter are battlegrounds. The company updated their Facebook page hours ago with comments including this: "Going forward, our intent is to leave the policy debate over same-sex marriage to the government and political arena." Some people have decided to stop eating at the fast-food chain known for their chicken sandwiches and cow mascot. Will the comments of the company president affect your decision to dine at Chick-fil-A?

Look at Mutations, Recombination

6 Sperm Genome Has Been Sequenced

Researchers at Stanford University have sequenced the entire DNA in 91 human sperm cells and hope the information obtained can help them in understanding infertility and other conditions. A sperm sample was obtained from a 40 year old man who had healthy children and previously had his genome sequenced. Researchers looked at the number of recombination events, which makes people a genetic combination of their ancestors and found an average of 23. Two sperm completely lacked some chromosomes and there were 25 to 36 mutations due to a change in one nucleotide, the building blocks of DNA that were only present in the man’s sperm. Researchers believe this knowledge could be used for the early detection of fertility problems in men and in screening for healthy sperm for in vitro fertilization.
