Scientist who discovered how our bodies feel the warmth of the sun or the hug of a loved one have won the Nobel Prize. David Julius and Ardem Patapoutian, from the US, share the 2021 prize in Medicine or Physiology for their work on sensing touch and temperature. They unpicked how our bodies convert physical sensations into electrical messages in the nervous system. Their findings could lead to new ways of treating pain. Heat, cold and touch are crucial for experiencing the world around us and for our own survival. But how our bodies actually do it had been one of the great mysteries of biology. With vaccination accelerating, he says Australians will soon "live with the virus" for the first time-that is, not try eliminate it. It's a drastic shift for a country used to seeing very few infection. Australia's strategy is to blocking foreign arrivals, hunting for every infection, and shutting state borders after outbreaks. Such measures have drawn critism for their cost to people's livelihoods and mental well being. But, until now, they have quelled outbreaks and allowed many Australians to live freely. Australia has learned many lessons from other countries such as reopen safely and fine-tune rist. Social distancing is a requirement at school, like they are in France and Mexico. With travel, could Australia rapid diagnostic tests used in Europe and North America? What's the best vaccine passport to allow movement safely? Singapore, which hit 80% this week, also ahead in its re-opening plans but is taking a cautious approach like Australia, keeping travel to save nations and maintaining restrictions like mask-wearing.
