Nowadays, children have become more eager to explore issues outside of the classroom. Anything from vehicular traffic to eye diseases are inspiring them to create. Next in line as America’s Top Young Scientist is Gitanjali Rao, whose handmade device detects lead contamination in water.
“I had been following the Flint, Michigan, issue for about two years,” [said] Rao… “I was appalled by the number of people affected by lead contamination in water and I wanted to do something to change this.”
The determined seventh-grader, with the help of her engineer parents and local universities, came through with Tethys. Using carbon nanotube sensors, the device can accurately detect lead and send information to any smartphone. She subsequently won the Young Scientist challenge and pocketed $25,000.
“Advice I would give to other kids would be to never be afraid to try,” Gitanjali said. “I had so many failures when I was doing my tests. It was frustrating the first couple of times, but towards the end, everything started coming together.”
Rao intends to invest part of the prize money into developing Tethys. The rest will fund her schooling — bright minds deserve the best education.
Dogs have been known to help people and fellow animals alike. From planting trees to assisting baby cheetahs, we can rest assured that they care about the world. After Hurricane Harvey, there is a particularly fascinating story involving our furry friends that caught my attention. Some surfing dogs are looking out for their own, raising funds for orphan pets.
The 12th annual surf competition for dogs raised $80,000 to help orphan pets at the Rancho Santa Fe-based Helen Woodward Animal Center, including more than 60 rescued dogs and cats from Hurricane Harvey.
The Surf Dog Surf-A-Thon lasted 6 hours and attracted over 5,000 guests. Dogs, separated into weight classes, surfed in 10-minute heats. To be honest, I’m not sure what I am more impressed with — the funds raised, the cause that the funds are supporting, or the fact that these dogs are practically amazing athletes.
The canine surf fest also included a costume contest for pooches to show off beach wear and freestyle surf competition, where points were awarded for creativity.
I am bummed to have missed such a lighthearted event. But more than that, I am also proud that our two-legged friends have been participating in relief efforts — and doing fantastic jobs at it! Truly, anything is paw-sible.
Preparing for life on Mars has become increasingly tedious, especially after discoveries of snow on the planet. Nevertheless, places like the UAE are eager to push forward the limits of space study, building a massive Mars metropolis. You know — just in case. But clearly, it’s MIT engineers who are coming out on top after snatching the top prize at the Mars City Design contest for their dome habitats.
MIT’s winning design, which the team calls Redwood Forest, is a collection of “tree habitats” connected through a system of tunnels called “roots.” The roots would provide safe access to other tree habitats, private spaces and “shirt-sleeve transportation,”
If the designs make it to Mars, each dome would house up to 50 inhabitants. Realistically, the ambitious tech team hopes to build 200, which guarantees 10,000 hopefuls a spot on life beyond Earth.
“On Mars, our city will physically and functionally mimic a forest, using local Martian resources such as ice and water, regolith (or soil), and sun to support life,” MIT postdoctoral researcher Valentina Sumini said.
It’s a daunting prospect, if it does happen. Hopefully MIT’s “forest” will make future residents feel right at home.
