Distance Matters

1 Anus-to-Scrotum Length Predicts Sperm Count

Most men have probably never considered their anus-to-scrotum length (anogenital distance), but researchers have studied how a shorter than average anogential distance is linked with low sperm counts. WebMD reports that the study from the University of Rochester found that men with shorter than average anogential distance are 7.3 times more likely to experience low sperm counts than men with a longer anus-to-scrotum length. Men with shorter anogential distance had poor sperm quality, including low sperm motility, low sperm concentration, low total mobile sperm count and poor sperm morphology. Almost a fourth of the 126 young men (mostly 19 years old) who volunteered for the study had low sperm counts. The research was published online in Environmental Health Perspectives.

The Core Area Has Three Jobs

2 Brain Has Three Layers of Short-Term Memory

Researchers have long debated whether the brain contains two or three layers of working memory, but new research by Rice University and Georgia Institute of Technology appears to prove that the brain contains three concentric layers of working memory. The working memory layers, or short-term memory, are where the brain stores readily available items. Researchers, publishing in Journal of Cognitive Psychology, believe that the short-term memory has three areas: the core that focuses on one active item, a surrounding area with at least three more active items, and a wider area containing passive items tagged for retrieval later. Researchers found that the core region (the focus of attention) has three purposes: direct attention to the correct item, retrieve item and update item.

No Reason to Stop Pap Smears

3 Older Women Should Get Cervical Cancer Screenings

Females aged 70 and older should not stop receiving regular Pap smears to check for cervical cancer, suggests a new study by the University of Pittsburgh Medical Center. The research findings, presented at the Society of Gynecologic Oncology's Annual Meeting on Women's Cancer, reveal that women aged 70 and older account for more than one of 10 cervical cancer cases in the U.S. Also, these older women are diagnosed more often with advanced cancer that's more difficult to treat than the cervical cancer found in younger women. WebMD reports that lead researcher Malgorzata Skaznik-Wikiel, MD, of Magee-Womens Hospital said that the rationale behind guidelines to discontinue cervical cancer screening in certain cases of women between ages 65 and 70 is unclear.

It Was No Joke to Mom

4 Flight Attendant Fired over Baby in Overhead Bin

A joke backfired when a Virgin Blue flight attendant put a 17-month-old baby inside an overhead compartment for peek-a-boo, reports the website Gadling. The infant's mother, passenger Natalie Williamson, told Australia's Sunday Herald Sun that she stood up and noticed people laughing, then said, "Get my son out of there now." The baby had been reportedly locked in the compartment for 10 seconds. Williamson, who was on a flight from Fiji to Sydney with her husband, has said that she's too traumatized by the incident to redeem the three free flights offered to her by Virgin Blue. According to the airline, Williamson's husband had been playing peek-a-boo with the overhead bin when the flight attendant decided to join in.

McDonald's Has More Revenue

5 Subway Outnumbers McDonald's in Locations

"All this may be good news for the restaurant giants, but on the whole, [it's] bad news for the consumer looking to eat healthy."
- Scallywag in the comments

In the fast-food wars, Subway appears to have won when it comes to number of locations, but McDonald's still makes more cash. NPR reports that Subway now has more than 34,000 locations in 95 countries, compared with McDonald's with a location count of more than 32,000 in 117 countries. McDonald's reported $24 billion in revenue last year, compared with $15.2 billion earned by Subway. The new largest restaurant chain has opened locations in non-traditional venues like an appliance store in Brazil, a riverboat in Germany, a Goodwill store in South Carolina, an automobile showroom in California and even a high school in Detroit, reports Wall Street Journal.

Makena Goes from $10 to $1,500

6 Drug for Preventing Preemies Costs More Next Week

Makena, a form of progesterone dispensed as a weekly shot for preventing premature births in high-risk women, will rise in cost from only $10 to $20 an injection to around $1,500 per shot, making the total cost during pregnancy as high as $30,000. Previously, the drug had been mixed by "special pharmacies that custom-compound treatments that are not federally approved," reports CBS News. Many obstetricians and the March of Dimes had supported KV Pharmaceutical becoming the sole provider of the drug. The change means more consistency and easier access to the drug. However, it seems that no one thought that giving KV Pharmaceutical government approval to exclusively sell Makena would result in such a huge price increase.

The Rhythm of Dementia

7 Arrhythmia After Stroke May Increase Dementia Risk

In a retrospective study the examined 15 previous studies involving a total of 46,637 people, researchers have determined that people who have had a stroke and have atrial fibrillation were at a 2.4 times greater risk of developing dementia compare to those who had a stroke and did not develop the arrhythmia. Atrial fibrillation results when the two upper chambers of the heart, the atria, do not beat in a coordinated manner. Twenty-five percent of those who suffered a stroke and had atrial fibrillation did develop dementia. Researchers hope these results will help in the development of treatments to prevent dementia and may result in more aggressive management of cardiovascular problems, particularly in stroke victims.

Cancer's Worst Enemy?

8 Animals Studies Suggest Nanodiamonds Fight Cancer

Researchers have demonstrated that nanodiamonds, tiny carbon particles, with chemotherapy drugs like doxirubicin attached to them have the ability to enter and shrink drug resistant breast and liver tumors. These results are very important because 90 percent of cancers that metastasize become difficult to treat due to drug resistance. Very high doses of doxirubicin that killed animals before the study was even finished were very well tolerated when bound to the nanodiamonds and the tumors shrank to the smallest sizes observed in the study. They are waste products from things like explosions, coal mines and oil refineries and processed to form particles only two to eight nanometers in diameter. More animals studies need to understand how it works before human clinical trials can begin.

CEREAL KILLERS SPOTTED in EUROPE

9 Cancer-Causing Cereal Boxes?

"That was one oddly written article by Fox. They seem to be trying to scare people out of using recycled cardboard boxes."
- Peggy in the comments

Swiss toxicologists are reporting that cancer-causing cereal boxes may be on the shelves of some European supermarkets. Certain types of recycled cereal boxes were shown to contain a high level of mineral oils that could potentially cause cancer. The mineral oils are thought to trace back to the ink from recycled newspapers used to make the boxes. European cereal brand Jordans has decided to discontinue the use of recycled cardboard boxes while Kelloggs and Weetabix both mull alternative eco-friendly options. American consumers have nothing to fear, as the process used to make recycled cereal boxes in Europe differs from the process used in America, says Deborah White, executive director at the Recycled Paperboard Technical Association.
