Placebos and lions

Two interesting articles today.

The first is in CNN.  It talks on placebos being effective in making our day better.   The article mentions " a 2010 survey of more than 400 docs found that a whopping 56% said they'd actually prescribed placebos to their patients".  In some manner or other the placebos seem to "solve" the patient's issues and makes him/her feel better.  What is interesting is that the placebo need not be in a medicinal form.  A study was conducted on two sets of students who were hooked onto equipment that the students thought measured the quality of sleep.  In reality, the machine did not measure the sleep quality.  In the morning, the researchers told one group of students that as per the equipment measured their quality of sleep was good.  The other group was informed the opposite.  The two group of students then went through a test.  Surprisingly, the group that thought they slept well performed better.  In this case, just the words "you slept well" were good enough and qualified as a placebo.  As the article states "Placebos seem to work in large part because they are given by authority figures".  The article then goes on to detail how we can trick ourselves and take advantage of the placebo effect.  The article is available at http://edition.cnn.com/2014/04/01/health/placebo-effect/index.html?hpt=hp_mid

BBC talks about the origin of the modern lions.  One fact that is noticeable is that currently there are two groups of lions.  The first is found in Eastern and Southern Africa and other group is found in Central and West Africa, and in India.  The article goes on to detail how the two groups emerged and how one of the groups reached India.  Of course, there is sadness in the fact that many species of lions have gone extinct - "Fewer than 400 Asian lions (P. leo persica) survive, living on the Kathiawar Peninsula of India".  The article is available at http://www.bbc.co.uk/nature/26736688
