Researchers continue to search for a brain booster to combat the cognitive effects of advancing age, and they may have found one in human umbilical cord blood. A study in the journal Nature shows that human cord blood injected into old mice significantly improved the function of their brains. Researchers were then able to isolate the responsible factor in the newborn blood, a protein called timp-2. Timp-2 injected into old mice produced the same effects. Researchers say the findings could lead to new treatments of age-related mental decline.
More women who’ve had cancer are having children, but those kids are more likely to be born prematurely, with a below average birth weight. A study in the Journal of the American Medical Association shows that breast cancer treatment produces nearly double the risk for preterm birth later, while cancers such as Hodgkins lymphoma increased the risk by 6%. Doctors don’t know if those children have greater health risks later on in life.
And finally, a study now proves that when people get their pictures taken, most of them say “take my left side. It’s my better side.” And when people view pictures, they perceive the left side of faces to be more expressive. That’s according to a study in the journal Brain and Cognition. Scientists explain that the left side of the face is controlled by the right side of the brain, which is more involved in emotion.
Women who’ve suffered a miscarriage and are trying to get pregnant again might want to think about taking a daily baby aspirin. A study in the Journal of Clinical Endocrinology and Metabolism tested women who had lost a previous pregnancy and scored high for inflammation in the body. Researchers found that those who took a daily low dose aspirin were 31 percent more likely to become pregnant than women who took a placebo and 35 percent more likely to carry the baby to term. However, researchers say it’s too early to recommend aspirin to prevent pregnancy loss.
Statistics show that obese girls don’t do as well in school as their thinner counterparts. But a new study in the journal Sociology of Education finds that at least part of the difference may be due to discrimination on the part of their teachers. Researchers say even when they score the same on ability tests, obese white girls receive worse grades than their thinner peers.
And finally here’s one more thing to put on the list of things to never eat—snow. And it doesn’t matter what color the snow is. A study in the journal Environmental Science, Processes and Impacts finds that snow is remarkably efficient at absorbing particulate air pollution that you find in car exhaust. It’s like a sponge. So catching snowflakes with your tongue may not be as pure as we thought.
Show Synopsis: Freezing eggs in their 30’s allows women to preserve fertility well into their 40’s. The concept was originally meant for women whose fertility was threatened by disease or medical treatment, but today the majority of those having eggs frozen are doing so for social or career reasons. Now egg freezing is even offered as a corporate benefit in some places. Experts discuss the procedure and its uses.
