America’s future as a science leader may depend on students like the ones you are going to meet tonight, teenagers from Lambert High School in suburban Atlanta. They may have just found a better way to detect and treat Lyme disease, which affects nearly a half million Americans annually. Their primary tool: the revolutionary gene editing technique known as CRISPR. 

And these CRISPR kids did it to try to prove they are the best in the world, competing at a kind of science Olympics in Paris called iGEM – short for International Genetically Engineered Machine. But to win, they would have to go up against teams from China, the rising power in biotechnology.

In Lambert High School’s lab, Sean Lee and his classmates are teenage genetic engineers, manipulating the building blocks of life.

Sean Lee: And what we’re gonna do is you’re going to move each of these samples into these mixes, and these mixes have everything we need in order to amplify our DNA.

bill Whitaker: It’s currently amplifying?

Sean Lee: yes. And we’ll have to do this three more times for our different samples.

We went to check out the iGEM team’s project for the big Paris competition. Their presentation seemed more like a pitch from a biotech startup than a public high school science class. Along with Sean,senior Avani Karthik is also a team captain. 

Avani Karthik: And so it’s a novel way of CRISPR that detects and so we have to create a guide RNA, and when that guide RNA is recognized the protein gets activated and it collaterally cleaves or cuts everything around it.Bill Whitaker: That just went right over my head. 

Avani Karthik: This is light years beyond my biology class, where the high point was dissecting frogs. This is called synthetic biology.

Sean Lee: A popular example of synthetic biology is golden rice where you’re able to engineer this rice to have the specific vitamins that you want so that it’s more nutrient dense. 

rohan Kaushik: And this would sound, like, cliché, but it’s just endless possibilities. So you can just do whatever you want with it, as long as it’s ethically correct. 

To compete at iGEM, you need to use synthetic biology to solve real world problems. 

These teens set their sights on finding a better way to detect and treat Lyme disease, something that has eluded adult scientists for decades. Transmitted by infected ticks, Lyme can cause arthritis, nerve damage and heart problems if left untre

High School Students Tackle Lyme Disease with Biotech Innovation

Lambert High School in Georgia is making waves in the world of biotechnology, thanks to its nationally recognized iGEM (International Genetically Engineered Machine) team. The programme’s success is attracting families from around the globe, with parents even relocating to the district hoping their children will have the opportunity to participate.

Competition for the roughly ten spots on the iGEM team is fierce, requiring a project proposal, a test, and an interview. Skills in engineering and coding are highly valued, as is a willingness to dedicate countless hours to the project. the team’s recent focus: Lyme disease.

With a month to go before the international competition in Paris, the students achieved a breakthrough. They developed a method to detect Lyme disease as early as two days after infection – substantially faster than the current two-week wait time for existing tests. Senior Claire Lee reported promising results in treating the disease as well.

“That’s the goal,” Lee stated, reflecting on the potential impact of their work. “We’re doing something in our high school lab that could potentially have a huge impact for, like, millions of people.It’s not like we’re just saying, like, ‘Oh.I’m just doing this little thing that–like, ‘It might help my grade.’ This thing could help save lives.”

While further testing is needed,the team is driven by the potential to revolutionize Lyme disease diagnosis and treatment. They are currently racing to finalize their results, code, and website presentation before the international competition. Notably, the team’s composition reflects a growing trend in STEM fields – the body is majority Asian-American, with the entire iGEM team comprised of children of immigrants.

CRISPR: The Gene Editing Revolution

CRISPR-Cas9,often simply called CRISPR,is revolutionizing the field of genetic engineering. It’s a powerful technology that allows scientists to precisely edit DNA,opening doors to potential cures for genetic diseases,improvements in agriculture,and a deeper understanding of life itself. But what exactly is CRISPR, how does it work, and what are the ethical considerations surrounding its use?

What is CRISPR?

CRISPR stands for Clustered Regularly Interspaced Short Palindromic Repeats. It’s a naturally occurring defense mechanism found in bacteria. Bacteria use CRISPR to defend against viruses. They capture snippets of viral DNA and integrate them into their own genome. If the virus attacks again, the bacteria use this stored DNA to recognize and destroy the virus.

Scientists have adapted this bacterial system to create a gene editing tool. The key component is the Cas9 enzyme, which acts like molecular scissors. Guided by a piece of RNA, Cas9 can cut DNA at a specific location in the genome. This allows scientists to remove, add, or alter DNA sequences with unprecedented precision.

How Does CRISPR Work?

The CRISPR-Cas9 system has three main components:

• Cas9 Enzyme: The “scissors” that cut the DNA.
• Guide RNA (gRNA): A short RNA sequence that guides Cas9 to the target DNA location. It’s designed to match the specific DNA sequence you want to edit.
• Target DNA: The specific sequence of DNA you want to modify.

Here’s a simplified breakdown of the process:

1. The gRNA is designed to match the target DNA sequence.
2. The gRNA and Cas9 enzyme form a complex.
3. This complex travels along the DNA until it finds the target sequence.
4. Cas9 cuts the DNA at the target location.
5. The cell’s natural repair mechanisms kick in. scientists can exploit these mechanisms to either disrupt a gene or insert a new one.

Applications of CRISPR

The potential applications of CRISPR are vast and rapidly expanding. Here are a few key areas:

• Treating Genetic diseases: CRISPR holds promise for correcting genetic defects that cause diseases like cystic fibrosis, sickle cell anemia, and Huntington’s disease. Clinical trials are already underway for several genetic disorders.
• Cancer Therapy: CRISPR can be used to engineer immune cells to better target and destroy cancer cells.
• Agriculture: CRISPR can improve crop yields, enhance nutritional value, and create disease-resistant plants.
• Drug Discovery: CRISPR can be used to create cellular models of disease,allowing researchers to test new drugs more effectively.
• Basic Research: CRISPR is a powerful tool for studying gene function and understanding the fundamental mechanisms of life.

Ethical Considerations

While CRISPR offers unbelievable potential, it also raises significant ethical concerns.Some of the moast pressing issues include:

• Germline Editing: Editing the DNA of eggs, sperm, or embryos (germline editing) would result in changes that are passed down to future generations. This raises concerns about unintended consequences and the potential for “designer babies.”
• Off-Target Effects: Cas9 can sometimes cut DNA at unintended locations, leading to unwanted mutations.
• Accessibility and Equity: Ensuring that CRISPR-based therapies are accessible to all who need them, regardless of socioeconomic status, is a major challenge.
• Dual Use Dilemma: The same technology that can be used to cure diseases could also be used for harmful purposes, such as creating bioweapons.

These ethical concerns are being actively debated by scientists, policymakers, and the public. Robust regulations and ongoing dialog are crucial to ensure that CRISPR is used responsibly and ethically.
