 Science is producing amusing results week by week investigating subjects and topics that may change the way our children will live their life a few decades from now on. Here is this week's selection:
Weight loss success linked with active self-control regions of the brainNew research suggests that higher-level brain functions have a major role in losing weight. In a study among 24 participants at a weight-loss clinic, those who achieved greatest success in terms of weight loss demonstrated more activity in the brain regions of the lateral prefrontal cortex associated with self-control.

An 18-nucleotide miRNA called miR-720 is produced in a predictable pattern as blood ages, which would allow sports officials to detect this kind of blood doping for the first time. The finding might also improve blood storage. Source: Duke University When fathers exercise, children are healthier, even as adultsMost parents know that the diet and exercise habits of a pregnant woman impacts the health of her baby, but little is known about how a father's health choices are passed to his children. A new study finds that lifestyle practices of fathers prior to conception may have a major impact on the lifelong health of their children.

The research revealed that gut microbiota composition at two years of life is associated with body mass index (BMI) at age 12. In addition, the BMI at age two was not significantly higher in children who later became overweight/obese, indicating that gut microbiota composition may be the earliest warning sign for detecting obesity.

They have done so by stimulating the body's so-called cold and nicotinic receptors.

Researchers have found that better cardiorespiratory fitness leads to longer life, with no limit to the benefit of aerobic fitness. Researchers retrospectively studied 122,007 patients who underwent exercise treadmill testing between Jan. 1, 1991, and Dec. 31, 2014, to measure all-cause mortality relating to the benefits of exercise and fitness.
