An invention from these college kids could help diagnose diseases earlier than ever.

This group of Australian students has invented a new way to diagnose diseases — and it could lead to a tool that's better than what we've got now.

It's got the power to save lives, and in a few years you may even see it on a cellphone.

In 2014, the team of undergrads entered a prestigious biomolecular design competition at Harvard University from halfway around the world — and took home first place.

They call themselves Team EchiDNA. They're a group of Australian undergrads led by Dr. Lawrence Lee of the Victor Chang Cardiac Research Institute in Sydney.

So how did they win? They looked at nature.

Together with Lee, the team designed the Cooperative Molecular Biosensor that can detect viruses and diseases. They drew their inspiration from the design models found in nature.

"By copying nature, we're constructing new technologies that can potentially be used to drive a rapid diagnostic device," Lee explained to me via email.

The Cooperative Molecular Biosensor is a tiny sensor made up of a ring of beacons that light up when they bind to the target DNA — of a virus, pathogen, or even mutation.

Is the virus present? If yes, the ring lights up. That's all there is to it. You can see more of a scientific explanation in their project video.

But the bottom line: more sensitive testing and fewer false positives. Yes!

A group of students pulling this off is impressive. The short time frame they did it in is even more so.

The team was made up of undergraduates, and as Lee describes, had many other student responsibilities to worry about.

"We started the project quite late with only a few months for everything to come together," he says, explaining the challenges they've faced. "The team consisted of undergraduate students who still had to attend lectures, submit assignments, and sit exams."

Giving hope to procrastinators everywhere!

Winning the contest was just the beginning. This invention has the potential to revolutionize the way we diagnose diseases like Ebola.

At the same time the students were busy winning awards for their invention, Ebola was wreaking havoc on parts of the world. And flat-out scaring the rest of it.

During the outbreak, Lee says, "there was a clear need for definitive and rapid diagnostics of Ebola so that patients could be identified, isolated, and treated quickly to stem the spread of the disease."

Because the initial symptoms of Ebola are so similar to those of other diseases (malaria, typhoid fever, other bad stuff), diagnosis in the early stages can be very difficult. With current technology, a patient may be in the hospital for multiple days before a positive Ebola diagnosis is made.

Team EchiDNA saw the need to rapidly diagnose Ebola and tailored their design to help fill that void.

The team created their design to target the DNA of the Ebola virus — although, as Lee explains, "I must stress that the capacity to detect Ebola DNA sequences in laboratory setting is a long way from robust and accurate diagnostics in patient samples."

In other words — the device is a long way from being sent into the field. But they are working to get there.

And once the design is perfected, it can be tailored to diagnose a wide range of other specific diseases: tuberculosis, HIV, or even a common flu.

So what's next? Lee said he and his lab (which still includes a couple members of the winning team) are working to refine the sensor and make it "so sophisticated you can test for bacteria or viruses by plugging a blood sample into your mobile phone," according to their press release.

Can you imagine!? A cell phone that diagnoses disease. Whoa. Image via Thinkstock.

These students should be so proud — and we should be so thankful for the young brains around the world helping to transform the future.

The technology being developed could drastically change the course of an Ebola outbreak — and other diseases — and stop it in its tracks before it can get out of hand. Life-saving!

When "bobcat" trended on Twitter this week, no one anticipated the unreal series of events they were about to witness. The bizarre bobcat encounter was captured on a security cam video and...well...you just have to see it. (Read the following description if you want to be prepared, or skip down to the video if you want to be surprised. I promise, it's a wild ride either way.)

In a North Carolina neighborhood that looks like a present-day Pleasantville, a man carries a cup of coffee and a plate of brownies out to his car. "Good mornin!" he calls cheerfully to a neighbor jogging by. As he sets his coffee cup on the hood of the car, he says, "I need to wash my car." Well, shucks. His wife enters the camera frame on the other side of the car.

So far, it's just about the most classic modern Americana scene imaginable. And then...

A horrifying "rrrrawwwww!" Blood-curdling screaming. Running. Panic. The man abandons the brownies, races to his wife's side of the car, then emerges with an animal in his hands. He holds the creature up like Rafiki holding up Simba, then yells in its face, "Oh my god! It's a bobcat! Oh my god!"

Then he hucks the bobcat across the yard with all his might.

Since March of 2020, over 29 million Americans have been diagnosed with COVID-19, according to the CDC. Over 540,000 have died in the United States as this unprecedented pandemic has swept the globe. And yet, by the end of 2020, it looked like science was winning: vaccines had been developed.

In celebration of the power of science we spoke to three people: an individual, a medical provider, and a vaccine scientist about how vaccines have impacted them throughout their lives. Here are their answers:

When John Scully was born, America was in the midst of an epidemic: tens of thousands of children in the United States were falling ill with paralytic poliomyelitis — otherwise known as polio, a disease that attacks the central nervous system and often leaves its victims partially or fully paralyzed.

"As kids, we were all afraid of getting polio," he says, "because if you got polio, you could end up in the dreaded iron lung and we were all terrified of those." Iron lungs were respirators that enclosed most of a person's body; people with severe cases often would end up in these respirators as they fought for their lives.

John remembers going to see matinee showings of cowboy movies on Saturdays and, before the movie, shorts would run. "Usually they showed the news," he says, "but I just remember seeing this one clip warning us about polio and it just showed all these kids in iron lungs." If kids survived the iron lung, they'd often come back to school on crutches, in leg braces, or in wheelchairs.

"We all tried to be really careful in the summer — or, as we called it back then, 'polio season,''" John says. This was because every year around Memorial Day, major outbreaks would begin to emerge and they'd spike sometime around August. People weren't really sure how the disease spread at the time, but many believed it traveled through the water. There was no cure — and every child was susceptible to getting sick with it.

"We couldn't swim in hot weather," he remembers, "and the municipal outdoor pool would close down in August."

Then, in 1954 clinical trials began for Dr. Jonas Salk's vaccine against polio and within a year, his vaccine was announced safe. "I got that vaccine at school," John says. Within two years, U.S. polio cases had dropped 85-95 percent — even before a second vaccine was developed by Dr. Albert Sabin in the 1960s. "I remember how much better things got after the vaccines came out. They changed everything," John says.
