Indian-American teen wins top science award worth USD 250,000

March 16, 2017

Washington, Mar 16: An Indian-American teen has won the top award, worth USD 250,000, in the oldest and most prestigious science and math competition in the US, for her research on preventing death of neurons due to brain injuries or neurodegenerative diseases.

Indrani Das, a 17-year-old resident of New Jersey, and four other Indian-origin students were among the top ten finalists to be honoured at the annual Regeneron Science Talent Search Awards Gala for their research projects demonstrating exceptional scientific and mathematical ability.

Forty finalists took home more than USD 1.8 million in awards.A contributor to neuron death is astrogliosis, a condition that occurs when cells called astrocytes react to injury by growing, dividing and reducing their uptake of glutamate, which in excess is toxic to neurons.

In a laboratory model, Das showed that exosomes isolated from astrocytes transfected with microRNA-124a both improved astrocyte uptake of glutamate and increased neuron survival.

Arjun Ramani, an 18-year-old student from Indiana won the third place honours worth USD 150,000 for blending the mathematical field of graph theory with computer programming to answer questions about networks.

Typically, these questions require statistical comparisons to hundreds or thousands of random graphs, a process that can take a relatively long time.

He developed an algorithm that greatly accelerated the process by reducing the time required to generate these graphs.

"Congratulations to the Regeneron Science Talent Search 2017 top winners," said George D Yancopoulos, President and Chief Scientific Officer of Regeneron.

"My experience as a Science Talent Search winner led me to embark on a career in science, and I hope it will inspire these exceptional young scientists to become the next generation of innovators that will improve the world and solve some of our most pressing challenges as a society," said Yancopoulos.

Archana Verma, 17, from New York, received a USD 90,000 award for her study of the molecular orbital energy dynamics of dyes, which may someday result in windows that produce solar energy.

Prathik Naidu, 18, from Virginia, received a USD 70,000 award for his creation of a new machine learning software to study 3D interactions of the human genome in cancer.

Vrinda Madan, 17, from Florida, received a USD 50,000 award for her study of 24 potential compounds for the treatment of malaria, in which she found two potential candidates that appear to target the disease-causing organism in a novel way and may warrant further study.

Of more than 1,700 high school seniors who entered the Regeneron Science Talent Search 2017, roughly 300 were named scholars in January.

Of those scholars, 40 students were named finalists and invited to Washington, DC to compete for the top 10 awards.

Seoul, Apr 26: A train presumed to belong to North Korean's Kim Jong-un has been spotted at a station in the state's eastern coastal town of Wonsan amid speculation about the leader's health, a US monitor said on Sunday, citing commercial satellite imagery on the region, Yonhap news agency reported.

According to 38 North-- a website devoted to analysis about North Korea, the imagery showed a train "probably belonging to Kim Jong Un parked at the Leadership Railway Station servicing his Wonsan compound since at least April 21."

"The approximately 250-metre long train, although partially covered by the station's roof, can be seen at a railway station reserved for use by the Kim family. It was not present on April 15 but was present on both April 21 and 23," it said.

"The train's presence does not prove the whereabouts of the North Korean leader or indicate anything about his health, but it does lend weight to reports that Kim is staying at an elite area on the country's eastern coast," it added.

The report came as rumours about his health have spread as Kim apparently skipped an important annual visit to the Kumsusan Palace of the Sun on the occasion of the April 15 birthday of late state founder and his grandfather, Kim Il-sung.

CNN intensified the speculation by reporting earlier last week that the United States is looking into intelligence that Kim is "in grave danger" after surgery.

Seoul officials have disputed recent media reports about Kim, saying there have been no unusual signs from the North. Some said that Kim is presumed to be staying in Wonsan for unspecified reasons.

Washington has also dismissed the reports, with US President Donald Trump calling such reports "incorrect" in a press briefing late last week.

On Saturday, other media reports stated that China has dispatched a team of medical doctors and officials to North Korea "to advise on" Kim, citing multiple unnamed people familiar with the situation.

North Korea's state media, however, has not made any mention of Kim's public activity for two weeks since he was last seen in April 11 presiding over a major party meeting, though it has reported on his handling of routine state affairs, such as sending diplomatic letters.
But not all speculation has proven to be false.

When he was absent from public for about a month in 2014, speculation arose about his health and a political crisis in the secretive state. He later reemerged with a cane and a limp reportedly after having a cyst removed from his ankle.

The 36-year-old leader is known to have various health problems apparently caused by obesity and heavy smoking. He took office as leader of the communist state after his father, Kim Jong-il, died of a heart attack in late 2011.

Houston, Jul 22: China said on Wednesday that the US has ordered it to close its consulate in Houston in what an official called an outrageous and unjustified move that will sabotage China-US relations.

Foreign ministry spokesperson Wang Wenbin condemned the action, which comes as tensions rise between the world's two largest economies. He warned of firm countermeasures if the US does not reverse its decision.

The unilateral closure of China's consulate general in Houston within a short period of time is an unprecedented escalation of its recent actions against China, Wang said at a daily news briefing.

There was no immediate confirmation or explanation from the U.S. side.

Media reports in Houston said that authorities had responded to reports of a fire at the consulate. Witnesses said that people were burning paper in what appeared to be trash cans, the Houston Chronicle reported, citing police.

Ninety per cent of a sample group of coronavirus-recovered patients from a prominent hospital in China's Wuhan city where the pandemic broke out have reported lung damage and five per cent of them are again in quarantine after testing positive for the virus, according to a media report on Wednesday.

A team at the Zhongnan Hospital of Wuhan University led by Peng Zhiyong, director of the hospital's Intensive Care Unit, has been conducting follow-up visits with '100 recovered patients' since April.

The first phase of this one-year programme finished in July. The average age of the patients in the study is 59.

According to the first phase results, 90 per cent of the patients' lungs are still in a damaged state, which means their lungs ventilation and gas exchange functions have not recovered to the level of healthy people, state-run Global Times reported.

Peng's team conducted a six-minute walking test with the patients. They found that the recovered patients could only walk 400 metres in six minutes while their healthy peers could walk 500 metres in the same period.

Some recovered patients have to rely on oxygen machines even three months after being discharged from the hospital, Liang Tengxiao, a doctor from the Dongzhimen Hospital, Beijing University of Chinese Medicine, was quoted as saying by the report.

Liang's team is also conducting follow-up visits with recovered patients aged above 65.

The results also showed that antibodies against the novel coronavirus in 10 per cent of the 100 patients have disappeared.

Five per cent of them received negative results in Covid-19 nucleic acid tests but positive results in Immunoglobulin M (IgM) tests, and thus have to be quarantined again, the report said.

IgM is usually the first antibody produced by the immune system when a virus attacks. A positive result in an IgM test usually means that a person has just been infected by the virus.

It is still unclear if this means these people have been infected again.

The 100 patients' immune systems have not fully recovered as they showed a low level of B cells -- - a primary force for killing viruses in the human body -- but a high level of T cells which only recognise viral antigens outside infected cells.

"The results revealed that the patients’ immune systems are still recovering," Peng said.

The patients also suffered from depression and a sense of stigma. Most of the recovered patients told the team that their families were not willing to have dinner with them at the same table, the report said.

Less than half of the recovered patients have returned to work, it said.

The findings are significant as the coronavirus first emerged in Wuhan city.

Hubei province for which Wuhan is the provincial capital has reported a total of 68,138 confirmed Covid-19 cases till now. The disease has claimed 4,512 lives in the province, according to the official data.

China reported 27 new confirmed Covid-19 cases on Tuesday, including 22 locally-transmitted cases, the National Health Commission (NHC) said on Wednesday.
