Pear Shapes Fare Worse

1 Weight Impairs Women’s Brain Function As They Age

Obese older women have worse memories than thinner ones, finds a study from Northwestern Med. In addition, pear-shaped women who carry their weight on their hips have worse memories than apple shaped women who carry theirs around their waists. The study is the first to correlate obesity and body shape with cognitive function. Using a specialized memory test on 8,745 participants, researchers found that for every one-point increase in a woman’s BMI, her memory score dropped accordingly. "The study tells us if we have a woman in our office, and we know from her waist-to-hip ratio that she's carrying excess fat on her hips, we might be more aggressive with weight loss," said lead author Diana Kerwin, MD. "We can't change where your fat is located, but having less of it is better."

Groups Investigate Shift Work

2 20 Possible Causes of Cancer

Three federal agencies and the American Cancer Society are targeting 20 possible causes of cancer for further investigation, reports MSNBC. The potential causes of cancer named by the groups include shift work, plus 19 chemicals: lead and lead compounds, indium phosphide, cobalt with tungsten carbide, titanium dioxide, welding fumes, refractory ceramic fibers, diesel exhaust, carbon black, styrene-7,8-oxide and styrene, propylene oxide, formaldehyde, acetaldehyde, dichloromethane, methylene chloride (DCM), trichloroethylene (TCE), tetrachloroethylene (perc, tetra, PCE), chloroform, polychlorinated biphenyls (PCBs), Di(2-ethylhexyl) phthalate (DEHP) and atrazine. All of the chemicals have been classified as possible carcinogens by the International Agency for Research on Cancer.

Fatso Tears off Chunks of Flesh

3 Drunk Man Tries to Ride Crocodile

While intoxicated, Michael Newman, a 36-year-old man, climbed into an enclosure at a wildlife park in Australia and attempted to ride on a saltwater crocodile, reports BBC. Earlier in the day, Newman had been kicked out of a local pub for being too drunk. Later, the man apparently scaled a fence at the wildlife park and attempted to sit on the 1,800 pound saltwater crocodile known as Fatso. The crocodile responded by tearing chunks of flesh from the man's right leg. Lucky for Newman, Fatso was a bit cold and sluggish, so he allowed the invading human to leave the enclosure and survive. Had the crocodile been more alert, the outcome would have easily been very different. The park's owner, Malcolm Douglas, claims that the crocodile is capable of delivering a single deadly bite.

Sniff Insulin to Boost the Brain

4 Insulin Improves Memory in Early Alzheimer's

Alzheimer’s patients or those with mild cognitive impairment who received insulin through their nose for four months improved their memory recall for two months. One hundred and nine patients with either condition without diabetes were either given a placebo or different doses of insulin placed in a nebulizer. Those who got a lower dose improved in both thinking and memory. Fifteen patients agreed to a spinal tap and researchers found that the proteins associated with Alzheimer’s were altered as well. While there is no recommendation to start treating patients with early Alzheimer’s in this manner, Dr. Suzanne Craft of the VA Puget Sound Health Care System and the University of Washington in Seattle, said “We believe our results are very promising and they warrant future trials."

The Ultimate Flu Vaccine

5 Two Flu Shots May Protect Against All Strains

NIAID is testing a flu vaccine that may end the need to produce a new one every flu season. The virus mutates a little every year, sometimes to a very virulent strain, such as H1N1, also known as “swine flu.” It would initially be given with the annual shot, but the hope is to end that. The vaccine is designed with much newer technology than grows the virus in chicken eggs. DNA based on the hemagglutin protein that is part of the virus is made and causes the body to produce an antibody to a part of the protein that is conserved between all strains. Flu strains from the years 1934 to 2007 were tested against the vaccine in ferrets and mice and they produced antibodies against them. The goal is to produce a vaccine that protects people for many decades or a lifetime.
