Science Weekly - 271018

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 and brain function
  • green leafy veggies against Age Related Macular Degeneration
  • how blood doping in sports can be caught
  • how a father's lifestyle prior conception can affect the child's health throughout their life
  • early obesity markers found in children
  • boosting weight loss by combining the effects of smoking and cold on mice
  • what role cardiorespiratpry fitness plays in longevity
  • alcohol causes changes in the brain that affect our memories and may promote addiction.

​Weight loss success linked with active self-control regions of the brain

New 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.

Eating leafy greens could help prevent macular degeneration

A new study has shown that eating vegetable nitrates, found mainly in green leafy vegetables and beetroot, could help reduce your risk of developing early-stage age-related macular degeneration (AMD).

New finding could unmask blood doping in athletes

Autologous blood doping, in which an athlete is transfused with their own stored red blood cells to increase their oxygen capacity for competition, might be detectable now with the use of a microRNA marker of blood aging. 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.

When fathers exercise, children are healthier, even as adults

Most 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.

Gut microbiota of infants predicts obesity in children

Evaluating the gut microbiota of infants may help identify children who are at risk for becoming overweight or obese. 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.

Researchers make mice lose weight by imitating effects from cold and nicotine

Inspired by some of the effects from winter swimming and smoking, researchers have found a way to improve the metabolism of mice and make them lose weight. They have done so by stimulating the body's so-called cold and nicotinic receptors.

Better cardiorespiratory fitness leads to longer life

Elite performers had an 80 percent reduction in mortality risk when compared to lower performers.
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.

Just a few drinks can change how memories are formed

Researchers have found that alcohol hijacks a conserved memory pathway in the brain and changes which versions of genes are made, forming the cravings that fuel addiction.
