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.

And that’s Medical Notes this week.

Medical Notes this week…

You may need to rethink your drink. A study in the journal Alzheimer’s and Dementia shows that excess sugar, especially the fructose in soda, may damage your brain. People who drink a lot of sugary beverages are more likely to have a poor memory, a smaller overall brain volume, and a significantly smaller hippocampus, a part of the brain that’s important for learning and memory. But researchers say don’t reach for lo-cal soda. Another study in the journal Stroke, shows that people who drink diet soda are nearly three times as likely to have a stroke and develop dementia as those who don’t drink diet soda.

Courses that teach mindfulness and meditation help women, but a new study shows they don’t help men at all. The study in the journal Frontiers in Psychology shows that while women are more prone to depression and downcast mood overall, learning mindfulness significantly helps them overcome it. However, men are mostly unaffected.

And finally, where a baby’s born makes a big difference in how much they cry. A study in the Journal of Pediatrics finds that on average, babies cry about two hours a day their first few weeks of life. Over three hours per day is officially a colicky baby. And you’ll find more of them in England, Canada and Italy than anywhere else. About a quarter to a third of babies there cry more than three hours a day. The lowest percentages were in Denmark and Germany, where only about five percent of babies spend so much time crying.

And that’s Medical Notes this week.
