Stem
cell therapies can be life changing, but they have only been
approved for a handful of conditions. That doesn’t stop
thousands of clinics around the world – including in the US,
Mexico, India and China – offering treatments for conditions
ranging from hair loss to Parkinson’s.
Some
of these clinics touting unproven stem cell treatments have
been endorsed by celebrities. Often desperate people are
shelling out thousands of dollars for treatments that can do
little good and can cause serous harm. Darius
Widera, a stem cell biologist, reports.
Every
year, lists of the most liveable cities on Earth are produced.
But in whose eyes are these cities
liveable? The people who do live in them, or near them,
may have very different criteria to those international groups
that asses them. And as parts of Europe and the US are hit by
more heatwaves,
what can be done to help deal with them? |

What
makes a city workable to many people is access to
informal labour markets, cheap travel options,
flexible housing and rental arrangements.
