The 2017 Nobel Prize for Medicine has been awarded to three American scientists.

Jeffrey Hall, Michael Rosbash and Michael Young were awarded for their discoveries of the molecular mechanisms controlling the circadian rhythm.


“Using fruit flies as a model organism, this year’s Nobel laureates isolated a gene that controls the normal daily biological rhythm,” the award committee said. “They showed that this gene encodes a protein that accumulates in the cell during the night, and is then degraded during the day.”

Circadian rhythms adapt one’s physiology to different phases of the day, influencing sleep, behavior, hormone levels, body temperature and metabolism.

The prize for physiology or medicine is first Nobel Prize awarded each year.

The prizes for physics, chemistry, literature and peace will also be announced from Tuesday to Friday respectively; and the prize for economics on Monday, October 9.

The prize comes with $1.1 million.

The UK government on Thursday announced that it will move India from the red to the amber list on Sunday, in the country's latest update to the 'Red-Amber-Green' traffic light ratings for arrivals into England amid the Covid-19 pandemic.

This means the visit visas for the UK from India are open, in addition to other long-term visas that have remained open. But travellers from India arriving in England can complete a 10-day quarantine at home or in the place they are staying (not mandatorily quarantine in a managed hotel).

Pakistan has failed miserably to protect Hindus, their interests.

A Hindu temple in Pakistan's Punjab province was reportedly vandalized by hundreds of people after a nine-year-old Hindu boy, who allegedly urinated at a local seminary, received bail, a media report said on Thursday.

According to the Dawn news report, the incident took place on Wednesday in Bhong town, about 60 km from Rahim Yar Khan city.

Besides the vandalization, the mob also blocked the Sukkur-Multan Motorway (M-5), the report added.

Citing sources, Dawn news said that a case was registered against the minor on July 24 based on a complaint filed by a cleric, Hafiz Muhammad Ibrahim, of the Darul Uloom Arabia Taleemul Quran.

The sources said that "some Hindu elders did tender an apology to the seminary administration saying the accused was a minor and mentally challenged".

But, when a lower court granted him bail a few days ago, some people incited the public in the town on Wednesday and got all shops there closed in protest, the report quoted the sources as further saying.

A video clip showing people wielding clubs and rods storming the temple and smashing its glass doors, windows, lights, and damaging the ceiling fans went viral on social media.
