Adolescent obesity is a national public health concern and, unchecked, places young people on a trajectory for a variety of health issues as they grow older. A new study from the University of Houston Department of Health and Human Performance (HHP) and Texas Obesity Research Center (TORC) suggests there is a relationship between long-term exposure to three specific types of family stressors and children becoming obese by the time they turn 18 years old.

Using data from the National Longitudinal Study of Youth, Assistant Professor Daphne Hernandez examined three family stress points ¬- family disruption, financial stress and maternal poor health - and applied those to data of more than 4,700 adolescents born between 1975 and 1990.

An unusual and very exciting form of carbon - that can be created by drawing on paper- looks to hold the key to real-time, high throughput DNA sequencing, a technique that would revolutionize medical research and testing. Led by Dr Jiri Cervenka and PhD candidate Nikolai Dontschuk from the University of Melbourne, the study also included scientists from the Australian Synchrotron and La Trobe University and is published in Nature Communications.

The Australian researchers have shown that graphene- a one-atom thick sheet of hexagonally arranged carbon, shaped like chicken wire - can detect the four nucleobases that make up DNA (cytosine, guanine, adenine and thymine).

Nutrition and metabolism are closely linked with reproductive health. Several reproductive disorders including polycystic ovary syndrome, amenorrhea, and ovarian cancer have been linked to malnutrition, diabetes, and obesity. Furthermore, fasting in numerous species can result in decreased fertility, because the development of immature egg cells, called oocytes, is arrested. Understanding how nutrients accumulate in immature oocytes will provide valuable insights into the link between metabolic disease and reproductive dysfunction.

Physical activity that makes you puff and sweat is key to avoiding an early death, a large Australian study of middle-aged and older adults has found.

The researchers followed 204,542 people for more than six years, and compared those who engaged in only moderate activity (such as gentle swimming, social tennis, or household chores) with those who included at least some vigorous activity (such as jogging, aerobics or competitive tennis).

They found that the risk of mortality for those who included some vigorous activity was 9 to 13 per cent lower, compared with those who only undertook moderate activity.

^lol, jk!! :)

In many casual discussions of language and the internet, it’s not uncommon to hear about how such “textspeak ruins language” – how technology has made everybody lazy with their speech and writing. Major media outlets such as the LA Times, the BBC and The Daily Mail have all bemoaned the ways in which people communicate through technology.

Researchers have made a significant breakthrough in the development of synthetic pathways that will enable renewable biosynthesis of the gas propane. 

Natural metabolic pathways for the renewable biosynthesis of propane do not exist but scientists at the Manchester Institute of Biotechnology (MIB), Imperial College and University of Turku have developed an alternative microbial biosynthetic pathway to produce renewable propane.
