Sadaf Farooqi, Professor of Metabolism and Medicine at the University of Cambridge, has been a pioneer in the genetics of obesity for more than twenty years, discovering more than a hundred common genetic variants as well as twenty single genes which can make people put on weight from early childhood. Twin studies have shown that about 40% of the variation in a person鈥檚 weight is influenced by their genes. And now she has discovered something brand new; why thin, but healthy people have genetic advantages in terms of maintaining a healthy weight. The research has just been published in the journal PLOS Genetics.

In the midst of political chaos and a worsening economic crisis that has seen rampant hyperinflation, widespread food shortages and spiralling crime, Venezuela鈥檚 public health system is in a state of collapse. Roughly one in twelve Venezuelans has left their homeland, and almost half of this migrant population is now living in neighbouring Colombia, which is struggling to cope with the rapid influx of new arrivals. Nowhere is the pressure on public health services greater than in C煤cuta, the largest Colombian city along the border with Venezuela and the point of entry for many. It has been estimated that around 35,000 Venezuelan migrants arrive in C煤cuta daily, of which up to 5,000 per day remain in Colombia. In the midst of this health crisis, there has been a mass exodus of pregnant women seeking safer conditions in which to give birth. Theo Hessing travelled to C煤cuta to find out more.

It can be hard to be positive when you are in a lot of pain, but self-belief might be just what the doctor ordered. Researchers from the University of East Anglia studied the progress of adults suffering from shoulder pain as they underwent physiotherapy, looking at 71 factors that could impact their success. They found that confidence in the ability to carry on with daily life and high expectations of recovery, were two of the three most important in making the biggest difference to pain and disability after six months. Lead author Dr Rachel Chester, a lecturer in Physiotherapy at the University of East Anglia, explained more about the power of positive thinking to Claudia.
