Nobel Prize honors discovery of temperature, touch receptors
Stockholm(AP): Two U.S.-based scientists were awarded the Nobel Prize in physiology or medicine on Monday for their discovery of the receptors that allow humans to feel temperature and touch.
David Julius and Ardem Patapoutian focused their work on the field of somatosensation, that is the ability of specialized organs such as eyes, ears and skin to see, hear and feel.
This really unlocks one of the secrets of nature, said Thomas Perlmann, secretary-general of the Nobel Committee, in announcing the winners. It's actually something that is crucial for our survival, so it's a very important and profound discovery.
The committee said Julius, 65, used capsaicin, the active component in chili peppers, to identify the nerve sensors that allow the skin to respond to heat.
Patapoutian found separate pressure-sensitive sensors in cells that respond to mechanical stimulation, it said. The pair shared the prestigious Kavli Award for Neuroscience last year.
Imagine that you're walking barefoot across a field on this summer's morning, said Patrik Ernfors of the Nobel Committee. You can feel the warmth of the sun, the coolness of the morning dew, a caressing summer breeze and the fine texture of blades of grass underneath your feet. These impressions of temperature, touch and movement are feelings relying on somatosensation."
Such information continuously flows from the skin and other deep tissues and connects us with the external and internal world. It is also essential for tasks that we perform effortlessly and without much thought, said Ernfors.
Perlmann said he managed to get hold of both of the winners before the announcement.
I (...) only had a few minutes to talk to them, but they were incredibly happy, he said. And as far as I could tell they were very surprised and a little bit shocked, maybe.
Last year's prize went to three scientists who discovered the liver-ravaging hepatitis C virus, a breakthrough that led to cures for the deadly disease and tests to keep the scourge from spreading though blood banks.
The prestigious award comes with a gold medal and 10 million Swedish kronor (over 1.14 million). The prize money comes from a bequest left by the prize's creator, Swedish inventor Alfred Nobel, who died in 1895.
The prize is the first to be awarded this year. The other prizes are for outstanding work in the fields of physics, chemistry, literature, peace and economics.

Elephant calf brought from Bijnor kept under care at Pilibhit Tiger Reserve
Pilibhit (PTI): A 19-day-old elephant calf, brought from Bijnor, was placed under care at the Pilibhit Tiger Reserve (PTR) on Sunday, an official said and added that the calf got separated from its mother in the forest area of Bijnor.
The calf was born on December 2 in the Bijnor forest area and got separated from its mother shortly after birth, the official said.
The forest department made several attempts to reunite it with its mother, but without any success. To ensure the calf's safety and better care, it was decided to transfer it to the Pilibhit Tiger Reserve on the instructions of senior officials.
On Saturday, Deputy Director Manish Singh received the calf. Special arrangements have been made in the reserve for its care. It has been kept in a safe and clean environment to provide it with a natural setting and protect it from external noise and disturbances.
Singh told reporters that raising an 19-day-old calf is challenging.
It requires a special diet as a substitute for mother's milk and constant monitoring.
He said a special team has been formed to provide 24-hour care. Since the calf is very young, it is being cared for like a newborn baby.
According to Singh, the primary responsibility for monitoring the calf's health has been entrusted to PTR's veterinarian, Dr Daksh Gangwar. Under his supervision, a complete record of the calf's health checkups, diet, and body temperature is being maintained. The team is ensuring that the calf does not contract any infection.
