She found that her system removed 70 to 80% of contaminates, including oxides of salt, detergents, oils, color dyes, and other floating particles. Lalita took the invention to her school's chemistry lab and performed the test again, this time running several qualitative tests
on the water before and after filtration.
Monday, we caught up with the 15-year-old high school student at the fifth annual Google Science Fair, a global competition and celebration of innovation, where he took home the LEGO Education Builder Award.
To make this system work, he created a super-thin film sensor printed with pressure-sensitive, electrically conductive ink and a coin-sized wireless circuit that can either be embedded in a sock or attached to a foot or shoe. When a patient steps out of bed, pressure causes the system to send an alert to an app that Shinozuka also designed and coded.
But the girls wondered, why wouldn't these bacteria be beneficial to other species — specifically grains like barley and oats, which are integral to our food supply. These nodules are only found on certain plants, including peas and beans.
By converting nitrogen from the air into helpful compounds like ammonia, the bacteria aid plant growth. While we usually think of bacteria as dangerous, these are actually helpful to the plants. The key to their success is a type of bacteria called rhizobia, which lives inside nodules, or the little nubs you sometimes see on plant roots.
A health care worker may hitch the VAXXWAGON's trailer to his bike, and cool the thermos with the power generated by simply turning the wheels on the trailer as it's pulled along. Cherry-picking bits of research from the labs of Princeton University professor Winston Soboyejo and Northwestern University student Rogers Feng, Ganesan realized that he could power a refrigeration system with mechanical power, rather than electricity.

And so "Talk" was born. Many AAC devices use eye tracking to help people communicate, but Dilbagi says that most of them are expensive and bulky, so he set out to make a faster and more affordable alternative.
These journeys, referred to as "last-leg" vaccine transportation, can last 15 miles or more. Often in developing countries, where proper medical attention may exceed a day's travel, vaccines are transported from hospitals to remote villages on foot, bicycle, motorcycle, or pack animal.
She hopes that the tool will serve as a cost-effective solution for cleaning ground water and industrial tanks on their property. Further chemical and physicals examinations are necessary before she can market it to farmers.
Not understanding what they were, Hickey brought one of the plants to her science teacher, who told her their benefits to plant growth. Hickey and her mother had found these nodules on the pea plants in their garden.
Beneficial bacteria
After 11 months of hard work and dedication, the three teen microbiologists discovered that they could make crops yield more food and shorten the time it takes a plant to sprout from a seed — a process called germination. They shorten this time by infecting the crops with a bit of bacteria that's been known to be advantageous to other crop plants.
Google will announce the top project in September, and the winner gets a 10-day trip to the Galapagos Islands, a visit to the Virgin Galactic Spaceport, and $50,000 in scholarship funding. Dilbagi is one of 18 incredibly intelligent teenagers who made it to this year's Google Science Fair finals.
Their project "Combating the global food crisis: Diazotroph Bacteria As a Cereal Crop Growth Promoter" aims to tackle issues of world hunger by exploiting a curious relationship they found between bacteria and certain plants. Hickey worked with her classmates Ciara Judge and Sophie Healy on their project. The three teenage girls, who live in Ireland, were simultaneously learning about plants and world hunger.
"I saw how it worked, and tried to re-engineer it so that it used no electricity and no ice to provide accurate refrigeration of vaccines while in transport. "I took a refrigerator apart," Ganesan says.
Upon arriving, they learned that the vaccinations were no longer effective. His grandparents carried him across 10 miles of remote terrain in India, the country of Ganesan's birth, so that he could receive a polio vaccination.
, speech impairments like Dysarthria and even Mutes to communicate and interact with the world like never before," Dilbagi writes. "In nutshell, Talk has the potential to change the world by enabling people with disorders like LIS, ALS etc. "It's my turn to change the world.
Dilbagi's Talk costs less than $100 and lets people communicate simply by varying their breathing. Another microprocessor will then synthesize and "speak" those words and sentences out loud. The Talk uses a micro-electrical-mechanical system (MEMS) microphone to interpret different breaths as either dashes or dots. The different breaths are interpreted as Morse Code, and then converted to words and sentences.He is also using the sensor data to study whether there's any correlation between his grandfather's daily activities and whether he wanders at night. During Shinozuka's six-month trial, his prototypes detected 100% of the 437 known times that his grandfather started wandering out of bed, without any false alarms.
Once, police found him on a freeway two miles away from his home. Shinozuka's grandfather suffered many accidents because his caregiver, Shinozuka's aunt, would seldom wake up when he started wandering.
In order to be safe and effective, vaccines must maintain a "Goldilocks temperature" between 2 and 8 degrees Celsius
— similar to a very cold refrigerator — from the time they leave the manufacturers to the moment they reach the patient. Hospitals will package the vaccine on ice, but this can easily backfire if the ice is too cold and freezes the vials, or if it melts before the vaccine reaches its destination.

Three young girls won the Google science fair on Sept. 22 with their innovative way to feed the world: treat plants with bacteria to help farmers grow more food, faster — without genetic modification.

The system stayed cool during both lab and outdoor tests, including an extensive total 200 hours of continuous testing. He attached the prototype to a bike to prove the energy from cycling could power the system.
The test uses the typical components of an Ebola test, which is made up of antibodies (the tags that our immune system uses to mark viruses and bacteria as invaders) and chemicals that cause the test to change colors if these antibodies bind to Ebola proteins in the sample.
Current methods of Ebola detection utilize enzyme-linked immunosorbent assay ("ELISA") detection kits which cost approximately $1,000 each, require complex instrumentation, trained medical professionals to administer, and up to 12 hours from testing to diagnosis.
With the help of a few professors, Ganesan studied thermodynamic design to come up with the method. His prototype system, which he calls the VAXXWAGON, can keep vaccines between the required 2 and 8 degrees Celsius for several hours using animal or human power.
Hallisey then used these silk-stabilized chemicals to design a paper-based test that requires only a serum sample (the clear part of the blood after the red blood cells have been removed) and water to run.
4% of the world's population suffers from some disorder that renders them almost completely paralyzed, forcing them to use an augmentative and alternative communication (AAC) device to communicate.

Feeling like she was onto something, Lalita got serious. She collected corn cobs from local farmers, washed them thoroughly with water, and dried them in the sun. Meanwhile, she began construction on a filtration system that could use the cobs.
While physical particles of dirt aren't great for your health, the big problem with dirty water is the disease-causing microorganisms that can live in it. To decontaminate the water, it can be boiled or iodine tablets can be added to it, Lalita believes.
While Ganesan plans to redesign his prototype again and again, making it easier to operate and more cost-efficient, he foresees his VAXXWAGON being used around the globe one day. He's filed a patent application and bought the domain name — well on his way to becoming the next great disruptor.

Trisha Prabhu, a 13-year-old from Chicago, won a spot as one of Google's 15 Global Science Fair finalists
for her project about stopping cyberbullying
by making teens and tweens think before posting hurtful comments.
She created a system to test her hypothesis called Rethink, which prompted students who said they would post a mean comment to think about how it might affect its target before posting it. 43% of her 533 trials, the student decided not to post the comment.
Now that she has successfully tested her hypothesis, Prabhu wants to create a real product that could work with social media sites and apps that would filter messages that were potentially mean or hurtful, and alert senders to take an extra second to think before posting.

Using homemade equipment, they chose to test rhizobia's affects on barley and oat seeds. In order to do this, the girls had to grow the bacteria and then infuse them into the seeds, which took many hours of preparation. A root-hacking plan
They attacked their work with meticulous detail.
The big innovation: To make the test stable, Hallisey used silk fibers to stabilize the chemicals on card stock, allowing them to sit around at room temperature for up to 3 weeks and still be effective. No refrigeration required, unlike with current Ebola tests.

After a memorable encounter with a tribal farmer, Lalita had the idea to repurpose those abandoned, dehydrated corn cobs as part of a water filtration system
. In the same way that a Brita filter traps unwanted particles as the water trickles into the pitcher, Lalita's invention uses corn to sponge up dirt in greywater collected from kitchen drain pipes and also from natural ponds.
The 15-year-old just won a spot as one of Google's 20 Global Science Fair finalists
