Case Studies Of STEM Projects

1. Case Study 1: MIT’s Development of CRISPR-Cas9 Gene Editing Technology

Project Overview:
This work shows how MIT researchers turned a bacteria’s natural defense into a tool to change DNA. They studied the CRISPR system and made it edit genes with great precision. MIT scientists Jennifer Doudna and Emmanuelle Charpentier led this effort.

Technical Approach:
First, they learned how bacteria and archaea use CRISPR to cut DNA at exact spots. Then they changed the Cas9 protein so it teams up with a guide RNA to find the right DNA sequence. This made it possible to cut almost any gene inside living cells.

Outcomes and Impact:
CRISPR-Cas9 changed genetic research by making gene edits fast and affordable in many organisms. It can help treat inherited illnesses, grow crops that resist disease, and speed up lab discoveries. Now, clinical trials are testing CRISPR therapies for sickle cell disease and some cancers.

Key Success Factors:
The team mixed expertise from structure, molecular, and bio labs to solve hard problems. They first studied the natural system before making any changes. They also shared their results openly so all scientists could build on their work.

Lessons Learned:
We saw that nature holds keys to new tools for big challenges. Studying basic biology can lead quickly to real solutions when teams follow clear steps.

2. Case Study 2: SpaceX Falcon 9 Reusable Rocket Development

Project Overview:
SpaceX set out to make a rocket that lands back on Earth for reuse. This plan aimed to cut launch costs and make space travel more common. The Falcon 9 team worked to break the rule that rockets are wasted after one flight.

Technical Approach:
Engineers built precise guidance, navigation, and control systems for soft landings. They added throttleable Merlin engines, folding grid fins, landing legs, and smart flight software. The team used fast prototyping and many tests to improve each part.

Outcomes and Impact:
Falcon 9 has flown over 200 missions and still succeeds almost every time. Launch costs fell from about $10,000 per kilogram to under $3,000 per kilogram. Reuse has let more companies and scientists send payloads to space more often.

Key Success Factors:
SpaceX challenged old ideas and pushed rapid test cycles. They built most parts in-house to keep control over quality and speed. Their team learned from each failure and grew stronger with each try.

Lessons Learned:
Asking “what if?” can spark big changes in any field. Building core skills inside your team speeds up progress and keeps standards high.

3. Case Study 3: Deep Learning Revolution at ImageNet Challenge

Project Overview:
In 2012, Alex Krizhevsky’s team used deep neural networks to win the ImageNet contest. They showed that many-layered networks could see and classify images much better than before. This result kick-started modern deep learning.

Technical Approach:
Their model, AlexNet, used eight layers of convolutional networks and ran on GPUs for fast training. They added ReLU activation, dropout to prevent overfitting, and data flips and crops to expand their dataset. They trained on over one million pictures across a thousand categories.

Outcomes and Impact:
AlexNet cut the top-5 error rate from 26% to 15%, a huge improvement in image recognition. This success led to deep learning work in self-driving cars, medical scans, face ID, and language tools. It proved that big data plus fast hardware can win big challenges.

Key Success Factors:
They mixed new ideas in network design with smart engineering for scale. Access to large labeled datasets and GPU power made the training possible. Open sharing of code and models let others build on their breakthrough.

Lessons Learned:
Big leaps come when algorithms, data, and compute unite. Open competitions drive fast progress and bring new ideas into the open.
