"The way I am trying to do that is by enhancing soil minerals that can bind up arsenic and make it inaccessible to rice plants," she told the American Bazaar. Pixabay

Four Indian American teenagers have been awarded $25,000 each for developing innovative approaches to address environmental issues.

The recipients of the award are Anjali Chadha (16) of Kentucky, Preeti Sai Krishnamani (17) of Delaware, Navami Jain (17) of North Carolina and Sai Preethi Mamidala (17) of Pennsylvania, the American Bazaar daily reported.


Chadha has built a device that is a sensor for detecting arsenic, a harmful substance known to cause cancer, in well water sources.

Currently a student at duPont Manual Magnet High School, Chadha was inspired to develop the sensor when she discovered that groundwater within 90 miles of her home was contaminated with arsenic.

It is estimated that some 50 million Americans use well water as their primary source and could be at risk for contamination.

For Krishnamani, the goal was to combat arsenic contamination in rice.

“The way I am trying to do that is by enhancing soil minerals that can bind up arsenic and make it inaccessible to rice plants,” she told the American Bazaar.

Jain performed a series of evaluations looking at different ways to produce bio-ethanol, a type of bio-fuel that is considered greener to conventional fossil energy sources as it is biodegradable and non-toxic.

“The major controversy around ethanol production is that it is being produced from food-based crops like corn. I’m looking at ways to produce it from agricultural-based matter and different waste products such as wheat straw,” she said.

Her results indicated that producing bio-ethanol from wheat straw may increase efficiency and lower costs.

Driven by the effects of fossil-fuel pollution in India, Mamidala studied an optimal catalyst to make renewable energy more accessible.

A senior at Garnet Valley High School in Glen Mills, she examined the catalyst in “a fuel cell that can store energy while it is being produced and generate it when it is needed. The actual catalyst being used in the fuel cell makes a world of difference in its performance”.

The four teenagers are all finalists of this year’s Regeneron Science Talent Search, the nation’s oldest and most prestigious science and math competition for high school seniors. (IANS)

Tokyo Olympics 2020 Indian wrestler Ravi Kumar enter semi finals.

Indian wrestler Ravi Kumar (57kg) and Deepak Punia (86kg) enjoyed fruitful outings at the Tokyo Olympic Games as they secured semifinal berths in their respective weight categories at the Makuhari Messe on Wednesday.

On the opening day of the wrestling competition, Ravi Kumar defeated Bulgaria's Georgi Vangelov 14-4 on technical superiority to reach the last-four in the men's 57kg category, while compatriot Deepak Punia overcame China's Zushen Lin 6-3 on points to advance to the semifinals.

Ravi Kumar will take on Nurislam Sanayev of Kazakhstan in the last-four, while Punia will be up against David Morris Taylor of the USA.

Earlier, Ravi Kumar had won his opening-round bout by technical superiority against Colombia's Oscar Tigreros to secure a quarterfinal spot. Competing in the Round-of-16 bout against the Colombian wrestler, the 23-year-old Ravi Kumar, who is making his Olympic debut, showed no nerves as he dominated the bout to win by technical superiority (13-2).

Ravi Kumar landed attack after attack and went 13-2 up, winning the bout by technical superiority with minutes to spare. In wrestling, building up a 10-point lead over the opponent results in a victory by technical superiority.

India's 86kg freestyle wrestler Deepak Punia showed no signs of the niggle that had forced him to pull out of the Poland Open Ranking Series in Warsaw in June, as he defeated Nigeria's Ekerekeme Agiomor on technical superiority to secure a quarterfinal berth.

He got his Olympic campaign to a fine start as he was in control from the start of the bout and hardly ever allowed his Nigerian opponent any room to maneuver his moves, finally winning with a 12-1 on technical superiority.

Punia, who had also suffered an elbow injury just before the Games, was slow at the start but came into his own as the bout progressed, inflicting takedowns at regular intervals to earn points.

The Indian wrestler eased into a 4-1 lead at the break and extended his lead comfortably in the second period.

Punia, the silver medallist from the 2019 world wrestling championships, then set up a clash with China's Lin Zushen in the quarterfinals and defeated him 6-3.
