Stockholm, Oct 8: The Nobel Prize in Physics was on Tuesday awarded with one half to James Peebles for his theoretical discoveries in physical cosmology and the other half jointly to Michel Mayor and Didier Queloz for discovering an exoplanet orbiting a solar-type star.

The prize was announced by Secretary-General of the Royal Swedish Academy of Sciences, Goran K Hansson.

"The 2019 Nobel Prize in Physics has been awarded one half to James Peebles for theoretical discoveries in physical cosmology and the other half jointly to Michel Mayor and Didier Queloz for the discovery of an exoplanet orbiting a solar-type star," the official Twitter handle of The Nobel Prize tweeted.

Nobel Prize is a set of annual international awards bestowed for outstanding work in fields of physics, chemistry, physiology or medicine, literature, economics, and the promotion of peace.

The discovery by laureates Michel Mayor and Didier Queloz started a revolution in astronomy and over 4,000 exoplanets have since been found in the Milky Way, a statement read.

"Strange new worlds are still being discovered, with an incredible wealth of sizes, forms and orbits," it read. This year's Physics Laureates Michel Mayor and Didier Queloz have explored our home galaxy, the Milky Way, looking for unknown worlds.

In 1995, they made the first discovery of a planet outside our solar system, an exoplanet, orbiting a solar-type star, 51 Pegasi.

Another Nobel Prize winner -- James Peebles took on the cosmos, with its billions of galaxies and galaxy clusters.

"His theoretical framework, developed over two decades, is the foundation of our modern understanding of the universe's history, from the Big Bang to the present day," it said.

This year's Nobel Prize in Physics rewards new understanding of the universe's structure and history, and the first discovery of a planet orbiting a solar-type star outside our solar system. The discoveries have forever changed our conceptions of the world.

On Monday, the Nobel Prize in Physiology or Medicine was jointly awarded to William G Kaelin Jr, Peter J Ratcliffe and Gregg L Semenza for their discoveries of how cells sense and adapt to oxygen availability.

Tehran, Feb 28: The coronavirus epidemic in Iran has cost 26 lives, the health ministry announced Thursday, with a vice president becoming the latest top official to be infected as the spread appeared to accelerate.

Health ministry spokesman Kianoush Jahanpour told a news conference that the tally of infections had risen to 245 with 106 more cases confirmed -- the highest number for a single day since Iran announced its first infections on February 19.

The Islamic republic has the highest death toll from the virus outside China, where COVID-19 first emerged.

Among the latest coronavirus sufferers is one of Iran's seven vice presidents, Massoumeh Ebtekar, who oversees women's affairs.

Ebtekar, a former spokeswoman for students who took 52 Americans hostage at the US embassy in Tehran in 1979, is being treated at home and members of her team have been tested, state news agency IRNA reported.

Mojtaba Zolnour, head of parliament's national security and foreign affairs committee, also contracted the virus, appearing in a video posted by Fars news agency saying he was in self-quarantine.

The cleric is a deputy for the Shiite holy city of Qom in central Iran where the country's first cases were detected.

According to media reports, among the deceased in Qom on Thursday was theologian Hadi Khroroshahi, who in 1981 was named Iran's first ambassador to the Vatican.

The announcement by Zolnour comes two days after another top official, deputy health minister Iraj Harirchi, head of the government's coronavirus task force, said he too had contracted the virus.

On Wednesday, Iranian authorities announced domestic travel restrictions for people with confirmed or suspected infections.

They also placed curbs on access to major Shiite pilgrimage sites, including the Imam Reza shrine in second city Mashhad and the Fatima Masumeh shrine in Qom.

Visitors to the shrines will be allowed to visit on condition they are provided "with hand-washing liquids, proper (health) information, masks", Health Minister Saeed Namaki said.

They must "not gather together in groups but just pray and leave", he said.

In a rare move, authorities announced the cancellation of the main Friday weekly prayers in Tehran, Qom and Mashhad as well as in the capitals of 22 of Iran's 31 provinces and other infected areas.

"All of these decisions are temporary and if the situation changes, we might intensify or ease them," Namaki said.

New Delhi, Mar 3: A day after two new cases of novel coronavirus that included one from Delhi were reported, the Health Ministry on Tuesday said six cases with "high-viral load" were detected during sample testing in Agra and these people have been kept in isolation. The six people had come in contact with a 45-year-old patient from Delhi, whose case came to light on Monday, and they include his family members.

According to government sources, the man, who is a resident of Mayur Vihar, had visited them in Agra.

The six have been kept in isolation at Safdarjung Hospital in Delhi and their samples are being sent to NIV, Pune for confirmation.

Contact tracing of the people who came in contact with the six is simultaneously being done through the Integrated Disease Surveillance Program (IDSP) network, the ministry said in a statement.

Sources said the patient from Mayur Vihar was shifted to a quarantine ward at Safdarjung Hospital on Sunday night.

His other family members have been asked to stay alert and look out for symptoms. One accountant, who came in contact with the man and some of his family members, was also quarantined, they said.

India on Monday reported two new cases of the novel coronavirus, one from Delhi and another one from Hyderabad. The government has stepped up its efforts to detect and check the infection which has killed 2,912 people in China.

On Monday, Rajasthan Health Minister Raghu Sharma had said that an Italian tourist tested positive for coronavirus in Jaipur.

The first sample collected from him on February 29 tested negative but his condition deteriorated, so a second sample was collected which tested positive on Monday, the minister said, adding, "Since there is a variation in the reports, the samples have been sent to the NIV, Pune for testing".

India had earlier reported three cases from Kerala, including two medical students from Wuhan in China, the epicentre of the deadly novel coronavirus. They had self-reported on their return to the country and tested positive for the infection. They were discharged from hospitals last month following recovery.

The infected person from Delhi had travelled to Italy, while the other patient who tested positive for the COVID-19 infection is from Telangana and had recently travelled to Dubai.

Both the patients had self-reported after they developed symptoms.

"They tested positive. They are stable and being closely monitored," ministry said on Monday.

The government has asked people to avoid non-essential travel to Iran, Italy, South Korea and Singapore and said India was in discussions with authorities in Iran and Italy, two countries badly affected by the infection, to evacuate Indians there.

The novel coronavirus or COVID-19, which originated in China, has spread to over 60 countries.

Jul 3: China under President Xi Jinping has stepped up its "aggressive" foreign policy toward India and "resisted" efforts to clarify the Line of Actual Control that prevented a lasting peace from being realised, according to a report released by a US Congress appointed commission.

The armies of India and China have been locked in a bitter standoff at multiple locations in eastern Ladakh for the last seven weeks, and the tension escalated after 20 Indian soldiers were killed in a violent clash in the Galwan Valley on June 15.

“Under General Secretary of the Chinese Communist Party (CCP) Xi Jinping, Beijing has stepped up its aggressive foreign policy toward New Delhi. Since 2013, China has engaged in five major altercations with India along the Line of Actual Control (LAC),” said a brief issued by US-China Economic and Security Review Commission.

"Beijing and New Delhi have signed a series of agreements and committed to confidence-building measures to stabilise their border, but China has resisted efforts to clarify the LAC, preventing a lasting peace from being realised,” said the report and was prepared at the request of the Commission to support its deliberations.

Authored by Will Green, a Policy Analyst on the Security and Foreign Affairs Team at the Commission, the report says that the Chinese government is particularly fearful of India’s growing relationship with the United States and its allies and partners.

“The latest border clash is part of a broader pattern in which Beijing seeks to warn New Delhi against aligning with Washington,” it said.

After Xi assumed power in 2012, there was a significant increase in clashes, despite the fact that he met Prime Minister Narendra Modi several times and Beijing and New Delhi have agreed to a series of confidence-building mechanisms designed to mitigate tensions.

Prior to 2013, the last major border clash was in 1987. The 1950s and 1960s were a particularly tense period, culminating in 1962 with a war that left thousands of soldiers dead on both sides, according to the records of China's People's Liberation Army, the report said.

“The 2020 skirmish is in line with Beijing’s increasingly assertive foreign policy. The clash came as Beijing was aggressively pressing its other expansive sovereignty claims in the Indo-Pacific region, such as over Taiwan and in the South and East China seas,” it said.

China is engaged in hotly contested territorial disputes in both the South China Sea and the East China Sea. Beijing has built up and militarised many of the islands and reefs it controls in the region. Both areas are stated to be rich in minerals, oil and other natural resources and are vital to global trade.

China claims almost all of the South China Sea. Vietnam, the Philippines, Malaysia, Brunei and Taiwan have counter claims over the area.

Several weeks before the clash in the Galwan Valley, Chinese Defence Minister Wei Fenghe called on Beijing to “use fighting to promote stability” as the country’s external security environment worsened, a potential indication of China’s intent to proactively initiate military tensions with its neighbours to project an image of strength, the report said.
