Brandeis Scientists Share Nobel Prize For Medicine

Scientists Jeffrey Hall, Michael Rosbash and Michael Young won the 2017 Nobel Prize for Physiology or Medicine for their discoveries of molecular mechanisms controlling our biological clocks, the award-giving body said on Monday.
Hall and Robash are affiliated with Brandeis University.
The mechanisms help explain issues such as why people traveling long distances over several time zones often suffer jet lag and they have wider implications for health such as increased risk for certain diseases.
“(The three scientists’) discoveries explain how plants, animals and humans adapt their biological rhythm so that it is synchronized with the Earth’s revolutions,” the Nobel Assembly at Sweden’s Karolinska Institute said in a statement.
The laureates used fruit flies to isolate a gene that controls the normal daily biological rhythm and showed how this gene encoded a protein that accumulates in the cell during the night and degrades during the day.
“The clock regulates critical functions such as behavior, hormone levels, sleep, body temperature and metabolism,” the Assembly said on awarding the prize of 9 million Swedish crowns ($1.1 million).
Thomas Perlmann, secretary at the Karolinska Institute Nobel Committee, described the reaction of Rosbash when first informed of the award: “He was silent and then he said ‘you are kidding me’.”
This is a moment of great uncertainty. Here’s what you can do about it.
We hope you appreciated this article. Before you go, we’d like to ask you to please support the Forward’s independent Jewish news this Passover. All donations are being matched by the Forward Board - up to $100,000.
This is a moment of great uncertainty for the news media, for the Jewish people, and for our sacred democracy. It is a time of confusion and declining trust in public institutions. An era in which we need humans to report facts, conduct investigations that hold power to account, tell stories that matter and share honest discourse on all that divides us.
With no paywall or subscriptions, the Forward is entirely supported by readers like you. Every dollar you give this Passover is invested in the future of the Forward — and telling the American Jewish story fully and fairly.
The Forward doesn’t rely on funding from institutions like governments or your local Jewish federation. There are thousands of readers like you who give us $18 or $36 or $100 each month or year.
Support our mission to tell the Jewish story fully and fairly.
