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.

Beijing, Feb 18: Police in China have arrested a prominent activist who had been a fugitive for weeks and criticised President Xi Jinping's handling of the coronavirus epidemic while in hiding, a rights group said Tuesday.

Anti-corruption activist Xu Zhiyong was arrested on Saturday after being on the run since December, according to Amnesty International.

China's ruling Communist Party has severely curtailed civil liberties since Xi took power in 2012, rounding up rights lawyers, labour activists and even Marxist students.

The death this month of a whistleblowing doctor who was reprimanded by police for raising the alarm about the deadly new virus before dying of it himself triggered rare calls for political reform and freedom of speech.

The "Chinese government's battle against the coronavirus has in no way diverted it from its ongoing general campaign to crush all dissenting voices," said Patrick Poon, China researcher at Amnesty International, in an emailed statement.

Another source, who spoke to news agency on the condition of anonymity, said Xu had been arrested in the southern city of Guangzhou.

Guangzhou police did not respond to requests for comment.

Xu went into hiding after authorities broke up a December gathering of intellectuals discussing political reform in the eastern coastal city of Xiamen in Fujian province, prior to the coronavirus crisis.

Over a dozen lawyers and activists were detained or disappeared after the Xiamen gathering, according to rights groups -- and Xu's detention appears linked to his presence at the meeting, explained Poon.

But while on the run, Xu continued to post information on Twitter about rights issues.

On February 4 Xu released an article calling on Xi to step down and criticised his leadership across a range of issues including the US-China trade war, Hong Kong's pro-democracy protests and the coronavirus epidemic, which has now killed nearly 1,900 people.

"Medical supplies are tight, hospitals are filled with patients, and a large number of infected people have no way to be diagnosed," he wrote. "It's a mess."

"The coronavirus outbreak shows just how important values like freedom of expression and transparency are -- the exact values that Xu has long advocated," Yaqiu Wang, China researcher at Human Rights Watch, told news agency.

But the disappearance of Xu illustrates how the Chinese state "persists in its old ways" by "silencing its critics", she said.

Xu -- who founded a movement calling for greater transparency among high-ranking officials -- previously served a four-year prison sentence from 2013 to 2017 for organising an "illegal gathering".

"That he was a fugitive for so many days while continuing to speak out, that in itself was... a kind of challenge to (Chinese authorities)," said Hua Ze, a long-time friend of Xu who told AFP she lost contact with the Chinese activist on Saturday morning.

Beijing/Wuhan, Apr 17: China's coronavirus death toll mounted to 4,632 on Friday as the country revised figures in its epicentre Wuhan with 1,290 additional fatalities amid international criticism of under-reporting of COVID-19 data.

The Wuhan municipal headquarters on Friday revised the number of confirmed COVID-19 cases and deaths due to the disease, state-run Xinhua news agency reported.

As of April 16, the total number of confirmed coronavirus cases in Wuhan was increased by 325 to 50,333 and the number of fatalities up by 1,290 to 3,869.

The revised figure raised China's overall COVID-19 death toll to 4,632. The total number of cases also increased to 82,692.

The Wuhan municipal headquarters in a notification said the revisions were made in accordance with related laws and regulations as well as the principle of being responsible for history, the people and the deceased.

The revision of figures came amid sharp criticism of China by the US and other nations for its alleged under-reporting of the coronavirus cases and cover-up of the origin of the viral strain, which emerged in Wuhan in December last, reportedly from the local Hunan sea food market.

Explaining the reason for the figure revision, the Wuhan municipality said it was done to ensure that the information on the city's COVID-19 epidemic is open and transparent, and that the data are accurate.

Listing the reasons for the data discrepancies, it said the surging number of patients at the early stage of the epidemic overwhelmed medical resources and the admission capacity of medical institutions. Some patients died at home without having been treated in hospitals.

Besides, during the height of their treating efforts, hospitals were operating beyond their capacities and medical staff were preoccupied with saving and treating patients, resulting in belated, missed and mistaken reporting.

Also, due to a rapid increase of designated hospitals for treating COVID-19 patients -- including those administered by ministries, Hubei Province, Wuhan city and its districts, those affiliated to companies, as well as private hospitals and makeshift hospitals -- a few medical institutions were not linked to the epidemic information network and failed to report their data in time.

The registered information of some of the deceased patients was incomplete, and there were repetitions and mistakes in the reporting, the Wuhan authorities noted.

Citing an official of the Wuhan municipal headquarters, Xinhua reported that a group for epidemic-related big data and epidemiological investigations was established in late March.

The group used information from online systems and collected full information from all epidemic-related locations to ensure that facts about every case are accurate and every figure is objective and correct.

"What lie behind the epidemic data are the lives and health of the general public, as well as the credibility of the government," the official was quoted by the report.

The timely revision of the figures, among other things, shows respect for every single life, the official said.

Meanwhile, the revised cases were not included in the overall national figures released by China's National Commission (NHC) in its daily report on Friday as it reports previous day's cases.

As per NHC data, as of Thursday the overall confirmed cases of coronavirus was 82,367, including 3,342 deaths.

As many as 1,081 patients are being treated and 77,944 people discharged after recovery, it said.

NHC said it received reports of 26 new confirmed COVID-19 cases from the mainland on Thursday, of which 15 were imported.

The other 11 new cases were domestically transmitted, it said, noting that five cases were reported in Guangdong Province, three in Heilongjiang Province, two in Shandong Province and one in Liaoning Province.

No death was reported on Thursday on the mainland.

As of Thursday, China has a total of 1,549 imported cases, NHC said, adding that 879 were undergoing treatment with 45 in severe condition. Besides, there were 66 new asymptomatic cases, taking the tally to 1,038.
