New York: Engineers, one of them of Indian-origin, have successfully developed a single-chip microprocessor that uses light for communications – a landmark development that opens the door to ultrafast, low-power data crunching.

The researchers packed two processor cores with more than 70 million transistors and 850 photonic components onto a 3-by-6-millimetre chip.


They fabricated the microprocessor in a foundry that mass-produces vbhigh-performance computer chips, proving that their design can be easily and quickly scaled up for commercial production.

The new chip marks the next step in the evolution of fiber optic communication technology by integrating into a microprocessor the photonic interconnects, or inputs and outputs (I/O), needed to talk to other chips.

“This is a milestone. It’s the first processor that can use light to communicate with the external world,” said Vladimir Stojanovic, associate professor of electrical engineering and computer sciences at the University of California-Berkeley.

No other processor has the photonic I/O in the chip.

Stojanovic and fellow UC Berkeley professor Krste Asanovic teamed up with Rajeev Ram at the Massachusetts Institute of Technology and Milos Popovi at the University of Colorado, Boulder, to develop the new microprocessor.

“This is the first time we’ve put a system together at such scale, and have it actually do something useful, like run a programme,” added Asanovic.

The team found the chip had a bandwidth density of 300 gigabits per second per square millimeter, about 10 to 50 times greater than packaged electrical-only microprocessors currently on the market.

The photonic I/O on the chip is also energy-efficient.

The achievement opens the door to a new era of bandwidth-hungry applications.

One near-term application for this technology is to make data centres greener.

According to the US Natural Resources Defense Council, data centres consumed about 91 billion kilowatt-hours of electricity in 2013 – about two percent of the total electricity consumed in the US.

Feminism itself is nothing but a simple movement that pursues equal rights for women (including transwomen) and against misogyny both external and internal.

"In India, to be born as a man is a crime, to question a woman is an atrocious crime, and this all because of those women who keep suppressing men in the name of feminism."

Feminism, a worldwide movement that started to establish, define and defend equal rights for women in all sections- economically, politically, and socially. India, being a patriarchal society gives a gender advantage to the men in the society thus, Indian feminists sought to fight against the culture-specific issue for women in India. Feminism itself is nothing but a simple movement that pursues equal rights for women (including transwomen) and against misogyny both external and internal. It states nowhere that women should get more wages than men, that women deserve more respect than men, that's pseudo-feminism.

Yakshi statue by Kanayi Kunjiraman at Malampuzha garden, Kerala

Kerala is a land of many good things. It has an abundance of nature, culture, art, and food. It is also a place of legend and myth, and is known for its popular folklore, the legend of Yakshi. This is not a popular tale outside the state, but it is common knowledge for travellers, especially those who fare through forests at night.

The legend of the yakshi is believed to be India's equivalent of the Romanian Dracula, except of course, the Yakshi is a female. Many Malayalis believe that the Yakshi wears a white saree and had long hair. She has a particular fragrance, which is believed to be the fragrance of the Indian devil-tree flowers. She seduces travellers with her beauty, and kills them brutally.

Ancient India not only made mentions of homosexuality but accepted it as well.


The LGBTQ+ acronym stands for Lesbian, Gay, Bisexual, Transgender, Queer, and others. In India LGBTQ+ community also include a specific social group, part religious cult, and part caste: the Hijras. They are culturally defined either as "neither men nor women" or as men who become women by adopting women's dress and behavior. Section 377 of the India Penal code that criminalized all sexual acts "against the order of nature" i.e. engaging in oral sex or anal sex along with other homosexual activities were against the law, ripping homosexual people off of their basic human rights. Thus, the Indian Supreme Court ruled a portion of Section 377 unconstitutional on 6th September 2018.
