Two Karnataka Teens win Google Science Fair Award for Developing Eco-Friendly Rubber

Published

[vc_row][vc_column][vc_column_text] Two teenagers, Aman KA and AU Nachiketha Kumar from Karnataka have developed an eco-friendly and cost-effective process of coagulating rubber using “bimbli” extract, a feat that has bagged them the National Geographic Explorer Award by Google.

Google launched the Google Science Fair in 2011 where students of 13 to 18 ages can submit experiments and their results in front of a panel of judges. The winner receives $50,000. The competition is also sponsored by Lego, Virgin Galactic, National Geographic and Scientific American.

Aman has said that their invention germinated from a story narrated by his mother on how his grandfather (who was in the rubber business for over four decades) would keep looking for alternatives when he ran out of formic acid, a vital ingredient in the coagulation of rubber latex to make sheets.

“We took bimbli fruit. Its scientific name is Averrhoa bilimbi. We extracted its juice and added 60 ml of it to a one-litre tray of rubber latex. We found that bimbli sped the process of coagulating rubber latex by 10 hours. While it usually takes formic acid close to 16 hours for the process, it took bimbli extract only six hours,” Aman told media personals.

“Not just the process got faster, the rubber sheets produced were of far better quality than sheets manufactured using formic acid,” said 16-year-old Kumar from Uppinangady village in Karnataka.

He further pointed out, “Usually after the coagulation process is over, the trays in which rubber sheets are formed are left behind with a residual solution of formic acid which is often disposed into the soil. Since the solution is very acidic, it depletes the soil and makes it unsuitable for agriculture in the long-run”.

“Bimbli also eliminates the use of any of these chemicals like para-nitrophenol, which gives colour to the sheets and forms a natural coagulant. The same process that requires 100 ml of formic acid can be executed with merely 60 ml of non-toxic bimbli extract, hence bringing down the cost,” he said.

The duo is among six winners who have been awarded by Google at its “Science Fair” in different categories. The fair had 24 finalists from 14 countries around the world this year.

The latest round of winners were announced on the afternoon of July 29th.

Other prize winners include an Ireland resident who wants to save the oceans by extracting harmful micro plastics from waste water; a student from Indonesia who set out to find affordable, non-invasive ways for members of her community to test their blood sugar levels; a Turkish science enthusiast who found a way to harness energy from tree vibrations; and a Russian student who wanted to find a better way to help those with impaired hearing communicate with the world around them.[/vc_column_text][/vc_column][/vc_row]

Five soldiers lost their lives and several others were injured when an Army vehicle veered off the road and fell into a deep gorge in the Balnoi area of Mendhar, Poonch district, Jammu and Kashmir, on Tuesday, according to officials.

The incident occurred as the vehicle, part of the 11 Madras Light Infantry (11 MLI), was traveling from Nilam Headquarters to Balnoi Ghora Post. Reports indicate that the vehicle plunged approximately 350 feet into a steep gorge near its destination.

Upon learning of the accident, the Quick Reaction Team from 11 MLI rapidly mobilized to the scene to initiate rescue operations. The injured personnel received immediate medical attention, and efforts are currently underway to evacuate them for further treatment.

In a message on X, the White Knight Corps expressed their deep condolences for the tragic loss of five courageous soldiers, stating, “All ranks of #WhiteKnightCorps extend their deepest condolences on the tragic loss of five brave soldiers in a vehicle accident during operational duty in the #Poonch sector. Rescue operations are ongoing, and the injured personnel are receiving medical care.”

“Today at around 17:40 hrs (5.40 pm), an Army vehicle of 11 Maratha Light Infantry, which was on its way from from Nilam headquarters to Balnoi Ghora Post along the LoC, met with an accident near Ghora Post,” said officials.

This incident follows a similar accident last month, where one Army personnel died and another was injured when their vehicle skidded off the road and fell into a gorge in Rajouri district, Jammu and Kashmir. This crash, which occurred on November 4 near Badog village in Kalakote, resulted in Naik Badri Lal and Sepoy Jai Prakash suffering critical injuries; Lal ultimately succumbed to his injuries while in treatment.

On November 2, another tragedy struck when a vehicle skidded off a hilly road in Reasi district, claiming the lives of a woman and her 10-month-old son, while three others sustained serious injuries.

In Himachal Pradesh, a significant snowfall in the past 24 hours has resulted in four fatalities and the shutdown of approximately 700 electric transformers along with over 350 roads, including three national highways. This has left around 500 vehicles stranded, among which are more than 300 buses.

The snowfall, which began yesterday, has been recorded in various districts such as Kinnaur, Lahaul and Spiti, as well as the higher elevations of Shimla, Kullu, Mandi, Chamba, and Sirmaur.

On a positive note, the situation has attracted a large number of tourists heading to Shimla and nearby areas in hopes of enjoying a white Christmas. According to MK Seth, president of the Shimla Hotel and Tourism Stakeholders’ Association, hotel occupancy in the historic town has exceeded 70%, 30% higher than usual.

Tragically, four individuals lost their lives in accidents over the last day, with several others injured due to vehicles skidding in hazardous conditions. Key national highways connecting Attari to Leh, Sanj to Aut in Kullu, and Khab Sangam in Kinnaur to Gramphoo in Lahaul and Spiti are currently blocked.

Among the affected areas, Shimla has the highest number of closed roads, totaling 89, followed by Kinnaur with 44 and Mandi with 25. The State Emergency Operation Centre reported that 683 transformers are inactive, leaving some regions without electricity.

Delhi Pollution: GRAP 4 revoked in capital, NCR as air quality improves

The Commission for Air Quality Management (CAQM) today revoked Stage 4 of the Graded Response Action Plan (GRAP) across Delhi and the National Capital Region (NCR). Nonetheless, measures under stages 1, 2, and 3 will remain in force to manage pollution levels. The GRAP 4 measures have been in effect in the entire NCR since December 16 after deterioration in air quality. 

This move follows after the Central Pollution Control Board (CPCB) reported an Air Quality Index (AQI) of 401 at 8 AM. The AQI on Monday fell into the severe category, measuring 403 at 7 am. Reportedly, AQI in several areas of the national capital was also recorded as ‘severe.’

Reports said, Anand Vihar recorded an AQI at 439, 456 at Ashok Vihar, 473 at Bawana, 406 at CRRI Mathura Road and 430 at Narela. Notably, an AQI between 0-50 is considered good, 51-100 is satisfactory, 101-200 is moderate, 201-300 is poor, 301-400 is very poor, and 401-500 is severe.

The GRAP 4 measures were implemented in Delhi after the air quality index (AQI) hit alarming levels on 16th December 2024. The Air Quality Index breached the 350 mark during the day, prompting the GRAP Sub-Committee to implement Stage-III measures. On the same day, by 10 PM, the AQI soared to 401, surpassing the severe plus category threshold. According to the Supreme Court instructions, Stage-IV measures were immediately introduced to tackle the crisis.

The apex court had earlier mandated precautionary measures, requiring Stage-III actions for AQI above 350 and Stage-IV for AQI exceeding 400. These directions were reiterated on 5th, 12th, and 19th December 2024, underlining the urgency to address Delhi’s air pollution.

As Delhi continues to battle hazardous air quality, the intensified measures under GRAP Stages I, II, and III will focus on curbing pollution sources and improving monitoring. Furthermore, residents are urged to remain cautious and adhere to guidelines issued by the authorities to mitigate the impact of air pollution on health and daily life.
