The Kaalink is a small cylindrical filter that attaches to a vehicle's exhaust tailpipe and collects carbon soot, which Graviky then turns into ink. The device is reusable and filters "between 85-95%" of soot emissions. While the filter doesn't stop CO2 gas from entering the atmosphere, the soot it does capture would otherwise be a highly dangerous environmental pollutant. That pollutant, called PM 2.5, can cause serious health problems like asthma and lung disease. Graviky Labs' entire process, from manufacturing the Kaalink, collecting and processing the soot, and producing the black ink, is carbon-neutral. Each 30 milliliter bottle of Air-Ink is equivalent to approximately 45 minutes worth of vehicular soot emissions.
In terms of improving air quality, Air-Ink can't compete with the improved technology that more recent cars use to combat pollution, but it can be applied to millions of older vehicles, especially in developing countries where pollution ordinances "are rare—or rarely enforced." According to Anirudh, "Pollution is nothing but resources we're not harvesting. We allow them to disperse because we've been ignorant of their value." Air-Ink may not be a cure-all for climate change, but Anirudh is hoping it's just one of many ways to start using pollution productively: "It's a start, and it can inspire several others to start looking at new forms of waste that are lying outside, unutilized."

Ketel Marte was brought to tears during an MLB game after facing a shameful fan taunt.
Baseball manager's poignant support for a player brought to tears after shameful fan taunt
Whether they’re expecting perfection from their favorite players or, worse, behaving callously toward opposing teams, sports fans often forget that athletes are human beings. But athletic competition has the ability to unify and uplift, even amid such painful and unpleasant encounters. Take, for example, a major-league baseball game held June 24, 2025 between the home team Chicago White Sox and visiting Arizona Diamondbacks.
A shameful low point occurred when Diamondbacks second baseman Ketel Marte was at bat in the seventh inning. Per ESPN, a fan reportedly yelled out a comment regarding Marte’s late mother, Elpidia Valdez, who died in a 2017 car accident in the Dominican Republic. Team personnel, including manager Torey Lovullo, then requested the 22-year-old fan be ejected. (Though he was remorseful and admitted his actions were inappropriate, according to an ESPN source, he was nonetheless banned indefinitely from all MLB ballparks.) "We commend the White Sox for taking immediate action in removing the fan," the MLB said in a statement. Marte reportedly declined to comment.

While the fan’s behavior is inexcusable, it did spark a powerful and inspiring moment. After hearing the comment, Marte was visibly upset, prompting Lovullo to walk on the field, put his arm around him, and offer some words of encouragement. "[I said,] 'I love you, and I’m with you, and we’re all together, and you’re not alone,'" Lovullo said in a post-game interview, as documented by The Rich Eisen Show. "'No matter what happens, no matter what was said or what you’re heard, that guy is an idiot.’"
According to Arizona Republic, Lovullo heard the fan’s comment but didn’t want to repeat it. “I looked right at [Marte] when I heard,” he said. “I looked right at him, and he looked at the person, as well. He put his head down and I could tell it had an immediate impact on him, for sure."
Elsewhere in the post-game interview, the manager called the moment "terrible" and reflected on why he stood up for Marte. "Fans are nasty, and fans go too far sometimes," he said. "I love my players, and I’m gonna protect them…I’ve known Ketel for nine years. He’s had some unbelievably great moments and some hardships as well and some really tough moments in his life. I know those. At the end of the day, we’re human beings, and we have emotions. I saw him hurting, and I wanted to protect him."

The following day, the Chicago White Sox X account sent out a message in support of Marte, writing, "We’re with you" and "Baseball is family." On The Rich Eisen Show, the show's host addressed the need to eradicate this kind of toxic athlete-fan interaction: "I was hearing [people saying], 'There’s no place for this in major league baseball.' There isn’t. There’s no place for this in our society. I understand that people are saying the MLB has got to do something about this. Fans have a right to heckle players—this is something that has happened forever…But there is a line."
In another recent, depressing sports moment with a beautiful coda, let’s look to Game 7 of the NBA Finals between the Indiana Pacers and the eventual champions, the Oklahoma City Thunder. During the first quarter, Pacers point guard Tyrese Haliburton tore his right Achilles tendon—a devastating injury that could potentially sideline him for most of the 2025-2026 season. Following the game, in a lovely display of sportsmanship, Thunder point-guard and league MVP Shai Gilgeous-Alexander went to the Pacers locker room to check on his competitor. In a press conference, he said, "You just hate to see it, in sports in general. But in this moment, my heart dropped for him. I can't imagine playing the biggest game of my life and something like that happening. It’s so unfortunate."
