Light from smartphones may lessen your sleep quality

Houston, Jul 29: Artificial light emitted from digital devices such smartphones and tablets could reduce the quality of your sleep, a study has warned.

The largest source of blue light is sunlight, but it is also found in most LED-based devices. Blue light boosts alertness and regulates our internal body clock, or circadian rhythm, that tells our bodies when to sleep.

This artificial light activates photoreceptors called intrinsically photosensitive retinal ganglion cells (ipRGCs), which suppresses melatonin, the hormone that signals your body that it is time to sleep.

"The most important takeaway is that blue light at night time really does decrease sleep quality. Sleep is very important for the regeneration of many functions in our body," said Lisa Ostrin, assistant professor at University of Houston in the US.

In the study, participants, aged between 17 and 42, wore short wavelength-blocking glasses three hours before bedtime for two weeks, while still performing their nightly digital routine.

Results showed about a 58 per cent increase in their night time melatonin levels.

"Those levels are even higher than increases from over- the-counter melatonin supplements," said Ostrin, who led the study published in Ophthalmic & Physiological Optics.

Wearing activity and sleep monitors 24 hours a day, the 22 study participants also reported sleeping better, falling asleep faster, and even increased their sleep duration by 24 minutes a night, according to Ostrin.

Ostrin recommends limiting screen time, applying screen filters, wearing computer glasses that block blue light, or use anti-reflective lenses to offset the effects of artificial light at nighttime.

Some devices even include night mode settings that limit blue light exposure.

"By using blue blocking glasses we are decreasing input to the photoreceptors, so we can improve sleep and still continue to use our devices.

That is nice, because we can still be productive at night," Ostrin added.

Washington, Feb 19: Sri Srinivasan, a prominent Indian-American judge, has created history by becoming the first person of South Asian descent to lead a powerful federal circuit court considered next only to the US Supreme Court.

Srinivasan, 52, became the Chief Judge of the United States Court of Appeals for the DC Circuit.

An Obama appointee who has already been considered for a Supreme Court seat twice, donned the mantle of the chief judge of the DC federal court circuit on February 12.

Srinivasan succeeded Judge Merrick Garland, who has been a member of the DC Circuit since 1997 and Chief Judge since 2013. He will remain on the bench, a press release said.

Notably, Garland's nomination to the Supreme Court by the then president Barack Obama was blocked by Senate Republicans in 2016.

Srinivasan, was appointed to the US Court of Appeals for the District of Columbia Circuit in May 2013.

He was the first ever Indian-American to be appointed to the second most powerful court of the US.

Neomi Rao, nominated by President Donald Trump, is the second Indian American on this powerful judiciary bench.

History being made on the DC Court of Appeals. Congratulations, Judge Srinivasan! Senator Mark Warner said.

Congratulations to Judge Sri Srinivasan on becoming the Chief Judge of the U.S. Court of Appeals for the D.C. Circuit! A milestone for the Indian-American/Kansan community (and yet another piece of evidence my family can use that I'm underachieving), US Federal Communications Commission Chair Ajit Pai said.

According to The Washington Post, Srinivasan spoke recently about his path to the bench at an event celebrating women in the law, a field where men still dominate leadership positions.

"Everybody doubts their belonging and worthiness in some measure. I definitely did and still do. This is just going to be a part of the thing when you're looking out in the world in which everyone isn't like you. It's natural to doubt whether you belong and whether you're worthy, he said, "but you do belong and you are worthy.

Born in Chandigarh, and raised in Lawrence, Kansas, he received a B.A. from Stanford University, a J.D. from Stanford Law School, and an M.B.A. from the Stanford Graduate School of Business.

Following graduation, he served as a law clerk to Judge J. Harvie Wilkinson III of the US Court of Appeals for the Fourth Circuit, as a Bristow Fellow in the Office of the US Solicitor General, and as a law clerk to US Supreme Court Justice Sandra Day O'Connor.

From 2011 until his appointment to the US Court of Appeals, Judge Srinivasan served as the Principal Deputy Solicitor General of the United States.

He has argued 25 cases before the US Supreme Court. He has also taught appellate advocacy at Harvard Law School as well as a seminar on civil rights statutes and the Supreme Court at Georgetown University Law Center.

New Delhi, Feb 27: An Indian Air Force aircraft on Thursday evacuated 76 Indians and 36 foreign nationals from the coronavirus-hit Chinese city of Wuhan.

The C-17 Globemaster III transport aircraft was sent to Wuhan on Wednesday and it carried 15 tonnes of medical supplies for coronavirus-affected people in China.

On its return, the aircraft brought back 112 people, including 23 citizens from Bangladesh, six from China, two each from Myanmar and the Maldives and one each from South Africa, the US and Madagascar.

Earlier, India had evacuated around 650 Indians from Wuhan in two Air India flights.

“In all 723 Indian nationals and 43 foreign nationals have been evacuated from Wuhan, China, in these three flights,” the Ministry of External Affairs (MEA) said.

On the medical supplies delivered by India to China, the MEA said they would help augment the country’s efforts to control the coronavirus outbreak which had been declared as a public health emergency by the World Health Organisation.

“The assistance is also a mark of friendship and solidarity from the people of India towards the people of China as the two countries also celebrate 70th anniversary of establishment of diplomatic relations this year,” it said.

Microsoft's Indian-origin CEO Satya Nadella on Monday voiced concern over the contentious Citizenship Amendment Act (CAA), saying what is happening is "sad" and he would love to see a Bangladeshi immigrant create the next unicorn in India.

His comments came while speaking to editors at a Microsoft event in Manhattan where he was asked about the contentious issue of CAA which grants citizenship to persecuted non-Muslim minorities from Pakistan, Bangladesh and Afghanistan.

"I think what is happening is sad... It's just bad.... I would love to see a Bangladeshi immigrant who comes to India and creates the next unicorn in India or becomes the next CEO of Infosys," Nadella was quoted as saying by Ben Smith, the Editor-in-Chief of New York-based BuzzFeed News.

In a statement issued by Microsoft India, Nadella said: "Every country will and should define its borders, protect national security and set immigration policy accordingly. And in democracies, that is something that the people and their governments will debate and define within those bounds.

"I’m shaped by my Indian heritage, growing up in a multicultural India and my immigrant experience in the United States. My hope is for an India where an immigrant can aspire to found a prosperous start-up or lead a multinational corporation benefitting Indian society and the economy at large".

The Centre last week issued a gazette notification announcing that the CAA has come into effect from January 10, 2020.

The CAA was passed by Parliament on December 11.

According to the legislation, members of Hindu, Sikh, Buddhist, Jain, Parsi and Christian communities who have come from Pakistan, Bangladesh and Afghanistan till December 31, 2014, due to religious persecution will not be treated as illegal immigrants but given Indian citizenship.

There have been widespread protests against the Act in different parts of the country.

In Uttar Pradesh, at least 19 persons were killed in anti-CAA protests.
