A 17-year-old girl just won herself a $150,000 college scholarship with her clever seaweed-based gel that effectively cleans polluted streams.
The Bangor, Maine aspiring MacGyver concocted an ingenious substance from seaweed to create an “alginate” gel that she mixed with aluminum and magnesium. Anchored in place by blocks of foam and plastic hair clips, she successfully trapped polluting phosphorus in local streams, earning her the Global Good Prize Award.
Teen genius Paige Brown
Paige Brown was shocked when she learned during one Bangor High School chemistry class just how much phosphorus polluted the local waterways. The phosphorus came from fertilizers farmers infused into their fields, which then leached and saturated the ground water, finally making its way into what Paige initially believed to be pristine streams.
The excess phosphorus from the fertilizer run-off caused an effect known as eutrophication, boosting the growth of algae, which in turn uses up all of the oxygen in the water while killing all the fish and other animals in the streams.
Paige analyzed the streams around her hometown for nine months and determined the highest phosphorus levels occurred just after heavy rains, which washed the fertilizer into the bodies of water. She decided to put together her own pollution cleaning filter, and used the most surprisingly practical and inexpensive materials for her project.
Styrofoam, check. Hairclip, check. Alginate, check. Total spend: $3.
Despite being so nondescript, Paige’s seaweed-based alginate gel mixed is mixed with magnesium and aluminum and formed into blobs and anchored into Styrofoam secured by plain plastic claw-type hair clips. When phosphorus in the streams come into contact with the alginate, they bind with the material and immediately precipitate, becoming solid enough to be picked out of the water.
Her invention cost her a total of $3 worth of materials put together.
Paige’s ingenious creation won her the Global Good Prize worth $150,000 in college scholarship money during this year’s Intel Science Talent Search.
Paige and what she calls her “scaffold.”
Her invention bears a potential to impact over 1.2 billion people around the world who lack access to clean drinking water due to eutrophication.
With Paige’s cheap, lightweight, biodegradable and effective phosphorus removal tool that filters the water, the straight A+ student has her sights set on removing E. coli bacteria from water sources next.
With environmentally aware teen geniuses like her around, the earth has a better chance of recovery.

This 80-Year-Old Granddad Walks 20 Kilometers Daily To Earn Money Selling Shrimp Paste
At 80 years of age, he should be enjoying life. Instead, he’s still working hard for his family.
For a meager income of $1.08 or Php50, an 80-year-old grandfather known as Manong Lauro walks 20 kilometers every day from his home in Bitukang Manok in Pandi, Bulacan to Real Cacarong.
This Manong (Mah-noh-ng-- a Filipino term earmarked for a person who is older than you), relentlessly walks the streets carrying a bucket-full of bagoong or shrimp/krill paste and sells it from house to house.
Dog with Two Noses Finds Forever Home Thanks to Freakshow Owner
…and the special pooch exhibits a talent that makes him one of the stars of an animal television show on AMC!
A freaky looking dog born with two noses got a second chance in life after he was adopted by a freakshow owner in Fresno.
Toby, a two-year-old dual-nosed Australian Shepherd was found abandoned on the streets and collared by a dogcatcher who brought him to a shelter back in 2014. Unfortunately, the "freak" of a dog was scheduled to be put down when luckily, his case caught the attention of an animal rescue group and Todd Ray.
This lucky dog now has a second chance (to go with his second nose) at life.
These Veterans Guard Chicago’s Most Dangerous Street To Make Sure Students Are Safe
Such a great way of contributing to the community and giving renewed purpose for our veterans! We thank you for your great service, LNVB!
Crimes are becoming more commonplace today. We hear news of people getting mugged while walking home from work and in some cases, we hear of children being abducted while on their way home from school. Chicago is no stranger to these crimes.
Some areas of Chicago, specifically the area around 35th Street and Martin Luther King Jr. Drive, are known to be particularly dangerous since the high schools located in that area have known gang affiliations. Along these most dangerous streets and other shady neighborhoods of Chicago, veterans stand around every day to make sure that students get to and from school safely. The patrol, aptly called Safe Passage, was established by non-profit organization Leave No Veteran Behind (LNVB). Established in 2011, the organization aims to provide a new purpose for military veterans and consequently build a safer community. LNVB works in conjunction with the Chicago Police Department in providing safe passage to some 8,000 students daily.
