Since 2020, the world has been wrapped in turmoil stemming from the COVID-19 pandemic, the war in Ukraine, and other economic issues. It is easy to miss that humans have managed to create many more things over the last three years than a vaccine.

Here are three scientific breakthroughs in five different fields that humans have made across the globe that prove otherwise.

Agriculture – Disease-free bananas

In 2020, scientists at the University of California, Davis developed a new efficient and cost-effective method for producing disease-free bananas. This method uses a technique called somatic embryogenesis, which allows scientists to grow plants from individual cells.

Medicine – 3D printing and Ai in Prosthetics

Prosthetic technology now incorporates 3D printing and AI into their construction to improve wearers’ range of motion, comfort, responsiveness and intuitiveness. 3D printing is being used to create custom-made prosthetics and orthotics that are more comfortable and functional than traditional devices and allows for the creation of prosthetics and orthotics that are specifically designed to fit the individual patient’s body.

AI-powered prosthetics can be controlled by brain signals, which allows the wearer to control the device with their thoughts. AI is also being used to develop orthotics that can monitor the wearer’s movements and adjust to provide support where it is needed.

Food – Lab-grown meat

The option of ordering meat from the supermarket that was grown in a lab over a farm is coming closer to reality with each passing day, Since 2022, the cost of a lab-grown burger fell to to $9.80 per burger from its cost of $330,000 per burger in 2020.

Cultured meat, also known as lab-grown meat or clean meat, is real meat that is grown in a laboratory from animal cells. It is produced using tissue engineering techniques pioneered in regenerative medicine. The process of growing cultured meat begins with taking a biopsy of cells from a live animal. These cells are then grown in a culture medium, which is a nutrient-rich solution that allows the cells to multiply and grow. As the cells multiply, they form muscle fibers, which eventually become meat.

Cultured meat has the potential to address a number of problems associated with traditional meat production, including animal welfare, environmental impact, and food safety.
