Over-stretching? Yoga
  Half a century after the Beatles meditated in Rishikesh, in the foothills of the Indian Himalayas, a new wave of spirituality tourists have arrived for this week’s International Yoga Festival. 
  Some 300 million people now practise yoga around the world, according to the International Yoga Federation. Since it became popular in the West in the 1980s it has moved beyond mere activity; in popular language use, it has become a “lifestyle” – on which Americans spent $16 billion in 2016. The yoga market is growing by 7% a year, while novelty yoga proliferates: hot yoga, beer yoga, naked yoga, goat yoga. 
  Some worry the practice is losing its spirituality and that the Instagram generation has made it about posing not poses. Others think it fills a spiritual vacuum in the irreligious West, where navel-gazing is not a tricky yoga move. Devotees defend its health benefits and positive messages of love, compassion and serenity. A noble position to take.

    Last month America’s unemployment rate climbed to

8,1%, the highest in a quarter of a century. For those

newly out of a job, the chances of finding another soon are

the worst since records began 50 years ago. In China 20m

[5] migrant workers (maybe 3% of the labour force) have

been laid off. Cambodia’s textile industry, its main source

of exports, has cut one worker in ten. In Spain the

building bust has pushed the jobless rate up by two-thirds

in a year, to 14.8% in January. And in Japan, where

[10] official unemployment used to be all but unknown, tens of

thousands of people on temporary contracts are losing not

just their jobs but also the housing provided by their

employers.

    The next phase of the world’s economic downturn is

[15] taking shape: a global jobs crisis. Its contours are only just

becoming clear, but the severity, breadth and likely length

of the recession, together with changes in the structure of

labour markets in both rich and emerging economies,

suggest the world is about to undergo its biggest increase

[20] in unemployment for decades.

THIS COULD PUT BIOPSIES OUT OF BUSINESS

At last month’s American Physical Society meeting, Dartmouth researcher Mary Ann Myeek described a new laser system that will help doctors identify a malignant tumor without having to do a biopsy. The laser system can detect slight chemical and structural changes in a tissue that may signify the very early stages of cancers. When tested on patients with colon polyps, this new detection method was just as accurate as conventional procedures.  

Normally, when a doctor finds a suspicious growth a piece of the tissue is removed and sent to laboratory for analysis. Getting the result can take days even weeks. Myeek’s new laser system, however, gives immediate answers, and it’s much less invasive than a biopsy. Myeek’s team tested the laser system on 17 patients who were undergoing routine colon examinations. Every time a polyp was discovered, doctor took a picture of the tissue’s molecular structure with the laser. For comparison, a tissue sample was also biopsied. In nearly every case, the two methods gave similar results. Myeek says this device could be widely available in a few years.
