Light-based memory chip that permanently stores data

London: A team of British scientists led by an Indian-origin professor has developed the world’s first entirely light-based memory chip to store data permanently that can help dramatically improve the speed of modern computing.

The new device uses the phase-change material — the same as that used in rewritable CDs and DVDs — to store data.

This material can be made to assume an amorphous state, like glass or a crystalline state, like a metal, by using either electrical or optical pulses.

The team has shown that intense pulses of light sent through the waveguide can carefully change the state of the phase-change material.

An intense pulse causes it to momentarily melt and quickly cool, causing it to assume an amorphous structure; a slightly less-intense pulse can put it into an crystalline state.

“This is a completely new kind of functionality using proven existing materials,” said professor Harish Bhaskaran from Oxford University’s department of materials.

“These optical bits can be written with frequencies of up to one gigahertz and could provide huge bandwidths. This is the kind of ultra-fast data storage that modern computing needs,” he noted.

Today’s computers are held back by the relatively slow transmission of electronic data between the processor and the memory.

“There is no point using faster processors if the limiting factor is the shuttling of information to-and-from the memory. But we think using light can significantly speed this up,” Bhaskaran explained.

For the study, the material scientists at Oxford University worked in collaboration with scientists at Karlsruhe, Munster and Exeter universities.

With this device, “we could read and write to thousands of bits at once, providing virtually unlimited bandwidth”, explained professor Wolfram Pernice from University of Munster.

The team is working on a number of projects that aim to make use of the new technology.

They are particularly interested in developing a new kind of electro-optical interconnect, which will allow the memory chips to directly interface with other components using light, rather than electrical signals.

The paper was published in the journal Nature Photonics.

JY Pillay: Indian Origin Civil Servant Appointed as the Acting President of Singapore

  • JY Pillay has been appointed as the acting President of Singapore
  • Pillay, also the Chairman of the Council of Presidential Advisers, is a veteran civil servant of Indian Origin
  • The Singapore polls take place on 23rd September

September 2, 2017: Indian-origin veteran civil servant JY Pillay on Friday took over as Singapore’s acting President until a new head of the state is elected later this month.

The temporary appointment of Pillay, Chairman of the Council of Presidential Advisers (CPA), follows the completion of President Tony Tan Keng Yam’s six-year term on Thursday, the Strait Times reported.

The nomination day for the Presidential election is September 13, followed by polling day on September 23.

According to the report, when the office of President is vacant, the first in line to exercise its powers is the CPA Chairman, followed by the Speaker of Parliament. This is the first time the office has fallen vacant since the elected presidency was introduced in 1991.

Pillay is no stranger to exercising the powers of the President. As CPA Chairman since 2005, he has been acting President each time the President goes on an overseas trip. He acted as President in May, when Tan made state visits to Europe.

He has served more than 60 such “stints”– the longest of which was 16 days in April and May of 2007 when then President SR Nathan visited Africa. (IANS)

Indian-Origin CEO Ravin Gandhi Faces Racism in The US for Criticising Trump After Charlottesville racial violence

  • He refused to defend US President Donald Trump’s economic agenda following the racial violence in Virginia
  • He said he will speak out against such abuse as long as he has a platform to do so

Washington, August 24, 2017: An Indian origin CEO says he was racially abused and was told to “go back” to India and also take along top Indian-American diplomat Nikki Haley after he refused to defend US President Donald Trump’s economic agenda following the racial violence in Virginia.

Ravin Gandhi, founder, and CEO of GMM Nonstick Coatings, a global supplier of coatings for cookware and bakeware, penned an op-ed for CNBC following the Charlottesville racial violence but in response was slammed and racially abused by readers, the Chicago Tribune reported.

 At least one woman was killed and dozens were injured in Charlottesville last week during clashes between white supremacists and counter-protestors at a rally. Trump, instead of blaming white supremacists, held both sides responsible for the violence and was criticised by both Democrats and Republicans for the response.

“I recently told the New York Times I was ‘rooting’ for certain aspects of Trump’s economic agenda,” Gandhi, 44, wrote in the article.

“After Charlottesville and its aftermath, I will not defend Trump even if the Dow hits 50,000, unemployment goes to 1 per cent, and GDP grows by 7 per cent… I will not in good conscience support a President who seems to hate Americans who don’t look like him.

“The fact that Trump equated hate groups with those protesting hate lit me up,” Gandhi said. “His moral leadership on this issue is reprehensible.”

US-born Gandhi, after his op-ed was published, received a voicemail from an alleged Trump supporter, who told him to “get your (expletive) garbage and go back to India”.

“You can take that other half-(expletive) Bangladesh creep with you, Nikki Haley,” the woman said in the message.

“She’s the one that started all this when she took down the Confederate flag. So don’t tell us that you gave him a chance. We don’t give an (expletive) who you gave a chance, OK? We’re going to start taking down Buddhist statues and see how you and Nikki Haley like that.”

The caller told Gandhi to “go clean up your own (expletive) country, it’s a filthy mess”.

He soon posted the voicemail on the social media and also shared the nastier emails he received, the report said.

“It was obvious that people thought my professional position somewhat protected me,” he said. “I wanted to show people that racism is blind to socioeconomics.

“Even though my race is a complete non-issue in my day-to-day life, the sad reality is there’s a group of racists in the USA that views me as a second-class citizen,” he said.

“I wanted my peers in the business community, the civic community, my friend community to see that this can happen to me. Because there’s this delusion that racism is dead because (Barack) Obama was elected (President),” Gandhi said.

He said while his sharing a “bigoted” voicemail may not make a big difference, he will speak out against such abuse as long as he has a platform to do so. (IANS)

Rahul, who lives in Barnet, beat his nine-year-old opponent, Ronan, 10-4 in the programme’s finale on Saturday night, the BBC reported.

Rahul, who has an IQ high enough to be a member of Mensa, the world’s largest and oldest high IQ society, fought off competition from 19 children aged eight to 12 in the week-long show.

He clinched the title by answering a question on 19th Century artists William Holman Hunt and John Everett Millais.

In the final, Rahul’s chosen subject was Edward Jenner’s medical innovation and methodology in 18th Century England. He and Ronan both scored 15 in their specialist fields.

Rahul said he was “extremely delighted to win” and congratulated Ronan and the other contestants, the BBC reported.

He had impressed audiences and quizmaster Richard Osman in the first round on Monday by answering every question he was asked correctly.

Rahul’s father, Minesh is an IT manager and mother Komal, a pharmacist. They entered him into the competition and called his success a “phenomenal achievement”. (IANS)
