Astronomers discover 83 supermassive black holes 13 billion light-years away

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.

Beijing/Zurich, Mar 4: China has approved the use of Swiss drugmaker Roche's anti-inflammation drug Actemra for patients who develop severe complications from the coronavirus as it urgently hunts for new ways to combat the deadly infection that is spreading worldwide.

China is hoping that some older drugs could stop severe cytokine release syndrome (CRS), or cytokine storms, an overreaction of the immune system which is considered a major factor behind catastrophic organ failure and death in some coronavirus patients.

Actemra, a biologic drug approved in 2010 in the United States for rheumatoid arthritis (RA), inhibits high Interleukin 6 (IL-6) protein levels that drive some inflammatory diseases.

China's National Health Commission said in treatment guidelines published online on Wednesday that Actemra can now be used to treat coronavirus patients with serious lung damage and high IL-6 levels.

Separately, researchers in the country are testing Actemra, known generically as tocilizumab, in a clinical trial expected to include 188 coronavirus patients and running until May 10.

Roche, which donated 14 million yuan ($2.02 million) worth of Actemra during February, said the trial was initiated independently by a third party with the aim of exploring the efficacy and safety of the drug in coronavirus patients with CRS.

It added that there was currently no published clinical trial data on the drug's safety or efficacy against the virus.

More than 3,000 people have died and 93,000 have been infected by the novel coronavirus thought to have originated in Wuhan, China, before spreading to around 90 countries including the United States, Italy, Switzerland, France and Germany.

The Swiss company, for which China is its No. 2 market behind the United States, also makes diagnostic gear to detect the coronavirus.

Since Actemra's approval a decade ago, it has become a go-to drug against other inflammatory conditions, including cytokine storms in cancer patients receiving cell therapies from Novartis and Gilead Sciences.

In 2012 it helped save the life of a young U.S. girl, the first child to be treated for leukaemia with Novatis' Kymriah, from a post-treatment rush of IL-6.

Priced at between $20-30,000 annually for RA according to SSR Health, Roche's medicine is also used for rare juvenile arthritis and giant cell arteritis, or inflammation of the blood vessels.

Jeddah, May 1: The government of India and its diplomatic missions in the Gulf Cooperation Council (GCC) States have begun elaborate preparations for the massive evacuation of their nationals stranded or needing to return once the lockdown travel restrictions are lifted.

The Indian missions in Saudi Arabia, the United Arab Emirates (UAE), Kuwait, Bahrain, Oman and Qatar have started registration for the return of their nationals. The move coincides with the directive of New Delhi to the Indian Air Force and Navy to get their big engines ready to bring back citizens stuck in the GCC states.

India’s External Affairs Minister S. Jaishankar has stated that the Indian missions in the GCC states have been liaising with local authorities for repatriation of Indians. More than eight millions Indians work and live in the Gulf countries.

The Indian Embassy in Saudi Arabia said that it has issued directives to their nationals who seek repatriation to India to fill an application form so as to facilitate their travel when the authorities lift the travel restrictions. Similar advisories have also been issued by the embassies in other Gulf States.

The Riyadh Embassy said in a press statement that the purpose is only to collect data and no decision has been taken yet regarding resumption of flights to India.

The Embassy will make an announcement with regard to repatriation of Indian nationals when the government of India takes a decision in this regard, the statement said, adding that separate forms have to be filled for each individual, including Indian worker or his or her family members.

The Embassy is in the process of working out the modalities of evacuation of stranded Indians in line with the directions of the government of India, the statement pointed out.

The Embassy and the Consulate General in Jeddah are closely monitoring the situation and are taking all the required measures to ensure the welfare of Indian citizens.

The missions have taken all the necessary measures for the supply of food, medicines and other emergency assistance to Indians in need and that is in coordination and cooperation with volunteers of major community organizations across the Kingdom.

These initiatives have been accelerated following the interactions of Ambassador Dr. Ausaf Sayeed with community volunteers and social workers from all parts of the Kingdom. The Embassy has also been in touch with all major companies in the Kingdom that employed Indian workers to carry out regular monitoring of the workers’ health, especially in labor camps, and take all other precautionary and preventive measures to ensure their health and safety.

According to the plan drawn up by the government of India, the first commercial flights from the Gulf could start after May 3, if the nationwide lockdown restrictions are not extended.

INS Jalashwa, an amphibious assault ship, and two Magar class tank-landing ships are being readied for the evacuation purposes, India’s IANS reported.

These ships, which have a total capacity of 2,000 people, have started making arrangements as per the standard protocols laid out to deal with suspected coronavirus cases like social distancing and sanitization.

The Indian Air Force has been evacuating citizens from coronavirus hit countries such as China, Japan, Iran, Italy and Kuwait since January. The force has stated that it has kept C-17 Globemaster and C-130s on standby which can be used whenever they are required.

Apart from them, Air India flights are also being kept on standby to pick up stranded Indians from the GCC countries.

15 Indian fatalities in western region

Speaking to Saudi Gazette, Indian Consul General Mohammed Noor Rahman Sheikh said that as of Thursday a total of 15 Indian coronavirus fatalities were reported in the western region.

These included seven cases in Makkah, six in Madinah and two in Jeddah. Around 140 Indians have tested positive in the region where most of the coronavirus cases in the Kingdom have been reported.

He said that permission was not accorded from the Ministry of Haj and Umrah to use the Indian Haj mission facility in Makkah as the center to assist the community members with regard to the coronavirus related cases.

“Our medical in charge is in Makkah and with the support of some other staffers, he has been actively involved in lending a helping hand to those Indian nationals who are in distress,” he said.

“We are in regular contact with the Ministry of Health officials in ensuring quick medical assistance to those who are tested positive.” He said preparations are under way for repatriation of Indians once permission is ready to take them home. “We are maintaining a database of all those who contacted the consulate with a request for their repatriation,” he added.

Meanwhile, the bodies of two Indians from the southern state of Kerala who succumbed to the pandemic were buried in Makkah. Naletil Muhammad from Ancharakkandi of Kannoor district, a restaurant worker in Makkah, gave samples at King Faisal Hospital a few days ago after developing symptoms of the disease.

When the hospital authorities advised him to remain in medical isolation, he reportedly preferred to remain in isolation at his residence where he succumbed to the pandemic after a few days.

Muhammad’s two sons, who are working in Riyadh, alerted his colleagues when they failed to contact him over phone. They found him dead at his residence on Monday. Eventually, Ministry of Health officials sent all his six colleagues to medical isolation.

Kottuwala Ippu Musliyar from Thennala, Vengara in Malappuram district, was a well-known social worker in Makkah. He died of coronavirus at Hira Hospital on Wednesday after undergoing treatment for a couple of days.

Mujeeb Pukkottoor, a prominent Indian social worker and general secretary of Makkah chapter of Kerala Muslim Cultural Center, was authorized by their spouses to carry out their burial procedures.

Accordingly Muhammad was buried on Wednesday and Ippu Musliyar on Thursday at the designated area for the coronavirus deceased persons at Sharaie Cemetery in Makkah.

Washington, Feb 6: U.S. president Donald Trump drew on staunch Republican support to defeat the gravest threat yet to his three-year-old presidency on Wednesday, winning acquittal in the Senate on impeachment charges of abuse of power and obstruction of Congress.

Only the third U.S. leader ever placed on trial, Trump readily defeated the Democratic-led effort to expel him from office for having illicitly sought help from Ukraine to bolster his 2020 re-election effort.

Trump immediately claimed "victory" while the White House declared it a full "exoneration" for the president -- even as Democrats rejected the acquittal as the "valueless" outcome of an unfair trial.

Despite being confronted with strong evidence, Republicans stayed loyal and mustered a majority of votes to clear the president of both charges -- by 52 to 48 on abuse of power and 53 to 47 on obstruction of Congress -- falling far short of the two-thirds supermajority required for conviction.

"Two thirds of the senators present not having found him guilty of the charges contained therein, it is therefore ordered and adjudged that the said Donald John Trump be, and he is hereby, acquitted," said Supreme Court chief justice John Roberts, who presided over the trial.

The months-long impeachment of the 45th US leader shone a harsh light on America's political divide, with Trump's core support base united behind him in rejecting it as a "hoax."

One Republican, senator Mitt Romney, a longtime Trump foe, risked White House wrath to vote alongside Democrats on the first count, saying Trump was "guilty of an appalling abuse of public trust." He voted not guilty on the second charge.

But the verdict was never truly in question since the House of Representatives formally impeached Trump in December, and has now cleared out a major hurdle for the president to fully plunge into his campaign for re-election in November.

Trump to speak Thursday

Responding to the verdict, Trump announced he would deliver a formal statement Thursday from the White House "to discuss our Country's VICTORY on the Impeachment Hoax!"

Shortly before, the president tweeted a montage depicting a fake cover of Time magazine declaring him president for all eternity.

The White House declared that Trump had obtained "full vindication and exoneration."

But Nancy Pelosi, the House Speaker and top Democrat in Congress, said that by clearing Trump, the Republicans had "normalized lawlessness."

"There can be no acquittal without a trial, and there is no trial without witnesses, documents and evidence," she said.

"Sadly, because of the Republican Senate's betrayal of the Constitution, the president remains an ongoing threat to American democracy, with his insistence that he is above the law and that he can corrupt the elections if he wants to."

Senate minority leader Chuck Schumer said the acquittal was "virtually valueless" since Republicans refused witnesses at his trial.

'Forever impeached'

The Democrats' intense 78-day House investigation faced public doubts and high-pressure stonewalling from the White House.

Concerned about the political risk for the party, Pelosi rejected a call early last year to impeach Trump on evidence compiled by then-special counsel Robert Mueller that he had obstructed the Russia election meddling investigation.

But her concerns melted after new allegations surfaced in August that Trump had pressured Ukraine for help for his 2020 campaign.

Though doubtful from the outset that they would win support from Republicans, an investigation amassed with surprising speed strong evidence to support the allegations.

The evidence showed that from early in 2019, Trump's private lawyer Rudy Giuliani and a close political ally, Ambassador to the European Union Gordon Sondland, were scheming to pressure Kiev to help smear Democrats, including Trump's potential 2020 rival Joe Biden, by opening investigations into them.

"We must say enough -- enough! He has betrayed our national security, and he will do so again," Adam Schiff, who led the House investigation, argued on the Senate floor this week.

"He has compromised our elections, and he will do so again," Schiff said.

'Colossal' mistake

In the trial, Trump's defence was not seen as having undermined the facts compiled by Schiff's probe, and several Republican senators acknowledged he did wrong.

But his lawyers and Senate defenders argued, essentially, that Trump's behaviour was not egregious enough for impeachment and removal.

And, pointing to the December House impeachment vote, starkly along party lines, they painted it as a political effort to "destroy the president" in an election year and insisted voters should be allowed to decide Trump's fate.

Senate majority leader Mitch McConnell said impeachment will benefit Republicans.

"Right now this is a political loser for them. They initiated it. They thought this was a great idea. At least for the short term, it has been a colossal political mistake."
