Washington, Mar 15: Astronomers have discovered 83 quasars powered by supermassive black holes 13 billion light-years away from the Earth, from a time when the universe was less than 10 per cent of its present age.

“It is remarkable that such massive dense objects were able to form so soon after the Big Bang,” said Michael Strauss, a professor at Princeton University in the US.

“Understanding how black holes can form in the early universe, and just how common they are, is a challenge for our cosmological models,” Strauss said in a statement.

This finding, published in The Astrophysical Journal, increases the number of black holes known at that epoch  considerably, and reveals, for the first time, how common they are early in the universe’s history.

In addition, it provides new insight into the effect of black holes on the physical state of gas in the early universe in its first billion years.

Supermassive black holes, found at the centers of galaxies, can be millions or even billions of times more massive than the Sun.

While they are prevalent today, it is unclear when they first formed, and how many existed in the distant early universe.

A supermassive black hole becomes visible when gas accretes onto it, causing it to shine as a “quasar.” Previous studies have been sensitive only to the very rare, most luminous quasars, and thus the most massive black holes.

The new discoveries probe the population of fainter quasars, powered by black holes with masses comparable to most black holes seen in the present-day universe.

The team used data taken with “Hyper Suprime-Cam” (HSC) instrument, mounted on the Subaru Telescope of the National Astronomical Observatory of Japan, which is located on the summit of Maunakea in Hawaii.

The researchers selected distant quasar candidates from the sensitive HSC survey data.

They then carried out an intensive observational campaign to obtain spectra of those candidates, using three telescopes: the Subaru Telescope; the Gran Telescopio Canarias on the island of La Palma in the Canaries, Spain; and the Gemini South Telescope in Chile.

The survey revealed 83 previously unknown very distant quasars.

New Delhi, Jun 4: India's Defence Secretary Ajay Kumar tested positive for COVID-19 on Wednesday, following which the defence ministry carried out a massive contact-tracing exercise, official sources said.

Kumar's condition is stable and he is currently under home-quarantine, they said.

At least 35 officials working at the ministry's headquarters in South Block in the Raisina Hills have been sent on home quarantine after reports of Kumar testing positive for the infection emerged on Wednesday morning.

There was no official comment on Kumar's health condition. The defence ministry spokesperson refused to comment on the issue.

It is learnt that Defence Minister Rajnath Singh did not attend office as part of a precautionary measure.

The offices of the defence minister, the defence secretary, the Army Chief and the Navy Chief are on the first floor of the South Block.

The sources said all laid down protocols on contact-tracing and quarantining of people are being scrupulously followed.

Feb 6: India has been ranked 40th out of 53 countries on a global intellectual property index, even as the country has shown improvement in terms of scores when it comes to the protection of IP and copyright issues, a top American industry body said on Wednesday.

India was placed at 36th position among 50 countries in 2019.

India's score, however, increased from 36.04 per cent (16.22 out of 45) in 2019 to 38.46 per cent (19.23 out of 50) in 2020, a 2.42 per cent jump in an absolute score.

However, India's relative score increased by 6.71 per cent, according to the International IP Index released by Global Innovation Policy Center or GIPC of the US Chambers of Commerce.

This year, it finds itself on the 40th place among 53 countries. Two new Index economies (Greece and the Dominican Republic) scored ahead of India. The Philippines, and Ukraine leapfrogged India.

"Since the release of the 2016 National IPR Policy, the government of India has made a focused effort to support investments in innovation and creativity through increasingly robust IP protection and enforcement," the GIPC said.

Since 2016, India has improved the speed of processing for patent and trademark applications, increased awareness of IP rights among Indian innovators and creators, and facilitated the registration and enforcement of those rights, it added.

According to the eighth edition of the annual report, India's score on the Chamber's International IP Index demonstrates the country's growing investment in IP-driven innovation and creativity. The Index specifically highlights a number of reforms over the last year that strengthen India's overall IP ecosystem, it said.

"In 2019, the Delhi High Court used dynamic injunctions to disable access to copyright-infringing content online, resulting in an increase in India's score on two of the copyright-related indicators," it said.

"The use of these injunctions places India alongside global leaders in copyright enforcement, including Singapore and the UK. As a result, India scores ahead of 24 other economies in the copyright indicators," the report said.

The Delhi High Court also issued a series of judgements that provide clarity on existing statutes related to trademark protection online, resulting in a score increase on one of the trademark-related indicators, it added.

The courts issued two precedential rulings that raised the bar for the damages awarded in IP-infringement cases and may provide a deterrent for future infringement. This resulted in an increase in score on one of the trademark-related indicators, it said.

Global Innovation Policy Center or GIPC said India also continues to score well in the Systemic Efficiency indicator, scoring ahead of 28 other economies in these indicators.

"This is a result of a concerted effort by the Indian government to consult with stakeholders during IP policy formation and create greater awareness about the importance of IP protection,” it said adding that India also remains a leader in the use of targeted incentives and IP assets for small and medium-sized enterprises (SMEs).

“To continue this upward trajectory, much work remains to be done to introduce transformative changes to India’s overall IP framework and take serious steps to consistently implement strong IP standards," the report said.

GIPC has identified several challenges for India. Prominent among them being patentability requirements, patent enforcement, compulsory licensing, patent opposition, regulatory data protection, transparency in reporting seizures by customs, and Singapore Treaty of Law of TMs and Patent Law Treaty.

"We are encouraged that Indian policymakers seem to recognize this Index as a valuable resource in their efforts to strengthen the country’s promising innovation ecosystem and enhance its competitiveness in an increasingly knowledge-based global economy,” the report said.

Observing that no other economy stands to gain more from strong Indian IP than India itself, the report said for example, no industry has been hurt more by copyright violations in India than the country’s own Bollywood industry, which loses almost USD3 billion to piracy each year.

"The number one way the Modi administration can demonstrate its commitment to the success of the Atal Innovation Mission, Accelerating Growth for New India’s Innovations, Make in India, Digital India, and Startup India is to strengthen its IP framework in ways that promote the legal and regulatory certainty necessary for greater R&D investment, high-value jobs, and greater innovative and creative outputs,” it said.

"Strong IP standards can further solidify India's position as the world’s fastest-growing economy, bolstering its reputation as a destination for doing business, foreign businesses’ ability to invest and make in India, thereby supporting the growth of India’s own innovative and creative industries," the report said.

Feb 26: In a midnight hearing, the Delhi High Court directed police to ensure safe passage to government hospitals and emergency treatment for those injured in the communal violence erupted in northeast Delhi over the amended citizenship law.

The court held a special hearing, which started at 12:30 am, at the residence of Justice S Muralidhar after receiving a call from an advocate explaining the dire circumstances under which the victims were unable to be removed from a small hospital to the GTB Hospital.

A bench of Justices S Muralidhar and Anup J Bhambhani directed the Delhi Police to ensure safe passage of the injured victims by deploying all resources at its command and on the strength of this order as well as to make sure they receive immediate emergency treatment if not at the Guru Teg Bahadur Hospital then at the Lok Nayak Jai Prakash Narayan Hospital (LNJP) or Maulana Azad or any other hospital.

The bench also called for a status report of compliance, including information about the injured victims and the treatment offered to them, and the matter will be heard during the day at 2:15 pm.

It said the order be communicated to the medical superintendents of the GTB and the LNJP Hospitals.

The urgent hearing was conducted after advocate Suroor Mander called the judge and sought urgent orders for safe passage of ambulances for the injured.

The Delhi Police and the government were represented through additional standing counsel Sanjoy Ghose.

During the hearing, the bench spoke over phone to doctor Anwar of the Al-hind Hospital in New Mustafabad who told the court that there were two bodies and 22 injured persons there and he had been trying to seek police assistance since 4 pm on Tuesday without success.

The court then directed the senior officials to reach to the hospital forthwith, following which they started the process of evacuating the injured to the nearest hospitals.

It also said this order be brought to the knowledge of the Delhi Police Commissioner.

Communal violence over the amended citizenship law in northeast Delhi claimed at least 18 lives till Wednesday.

On Tuesday, the violence escalated in northeast Delhi as police struggled to check the rioters who ran amok on streets, burning and looting shops, pelting stones and thrashing people.
