CIA Agents Must Be Exhausted

1 Secrets Burden Us Like Actual Weights

A series of behavioral experiments reported by Tufts University psychologists indicates that having to keep a secret is not only stressful, but is experienced as an actual physical burden, and the more important the secret, the heavier the sense of weight. Subjects were asked to recall either trivial or meaningful secrets, or to conceal either important or insignificant facts during an interview, and then asked to rate various tasks. Those in the "major secret" group judged hills to be steeper, distances from a target to be greater, and various household tasks to be more strenuous than the "minor secret" keepers. Their conclusion: the more burdensome a secret, the more we behave as if it were a physical weight, and some secrets can be literally exhausting, perhaps even harmful.

FDA Says Fess Up

2 Tobacco Must Disclose Harmful Chemicals

Companies that make tobacco products must start telling consumers about all of the harmful chemicals inside the products, ruled the FDA on Friday. Tobacco companies also have to prove their "reduced harm" claims. The FDA was able to make this ruling under the new Family Smoking Prevention and Tobacco Control Act, reports WebMD. While there are more than 7,000 chemicals inside tobacco products, the list of harmful chemicals that must be reported includes only 93 chemicals. This is the first time that all tobacco importers and makers will have to report the quantities of possibly harmful chemicals and chemical compounds in each regulated tobacco product offered for sale in the U.S., says the director of the FDA's Center for Tobacco Products, Lawerence Deyton, MD.

Moms Today Take 2.5 Hours Longer

3 Baby Delivery Times Longer Than 50 Years Ago

Today, most first-time moms take 6.5 hours to give birth, while first-time mothers 50 years ago took barely four hours, finds a new federal study. NPR reports that the research reveals that first-time mothers today are four years older on average, and they weigh more too. Also, babies born today are 4 ounces heavier than in the 1960s. However, the researchers believe that the important causes for longer labors today have more to do with medicine. Use of epidural anesthesia, known to increase labor up to 90 minutes, is given to up to 85 percent of modern mothers, compared to only 4 percent in 50s and 60s. Yet, 19 percent of women today also receive the drug oxytocin, which may shorten labor time. The study is published in American Journal of Obstetrics and Gynecology.

Superinfection = Super Antibody

4 Two HIV Strains Increase Antibody Activity

Results from a study involving 12 women infected with two strains of HIV, known as a “superinfection,” and three healthy controls found that having both strains present increased the presence of “elite neutralizing” antibodies that could target multiple strains of the virus that causes AIDS over a long period of time. Not only were more of these antibodies in superinfected women, but they were more potent in their ability to neutralize the virus. Researchers hope this study sheds light on how to design an effective vaccine. Previous attempts at developing one have only yielded moderate success. Anti-HIV antibodies do inhibit infection and this study shows that a mixture of different viral strains could be the best approach to eliciting a strong antibody response from the immune system.
