What Do We Do With E-waste? Flash Joule Heating Presents a Solution

With Apple rolling out a new iPhone every year and planned obsolescence encouraging consumers to buy and throw out more and more electronics, electronic waste is piling up in landfills globally. An article published in October this year proposes flash Joule heating as a potential solution to the millions of tons of e-waste produced every year.

With Apple rolling out a new iPhone every year and planned obsolescence encouraging consumers to buy and throw out more and more electronics, electronic waste is piling up in landfills globally. Over 40 million tons of e-waste are produced annually, making it the fastest growing category of solid waste globally. E-waste often includes heavy toxic metals that can leach into the surrounding environment, contaminating soil, water, and food sources. Workers who dispose of e-waste have been found to have higher lead content in their blood because of exposure to dangerous dust and smoke when working with the waste and in...
Nobel Prize in Medicine Awarded for Discovery of Temperature and Touch Receptors

Nobel Prize in Medicine Awarded for Discovery of Temperature and Touch Receptors

The 2021 Nobel Prize in Physiology or Medicine was awarded for research on how we feel temperature, touch, and bodily spatial awareness. This discovery marks a key breakthrough in our previously limited understanding of our sense of touch.

This year’s Nobel Prize in Physiology or Medicine was awarded to David Julius and Ardem Patapoudian for their discoveries of receptors for temperature and touch, marking a key breakthrough in our understanding of how mechanical stimuli are converted into electrical impulses in the nervous system. Sight, hearing, touch, smell, and taste, our five major senses, connect our bodies and brains to the world. A sixth sense, proprioception, which helps our body know where it is...
Seaweed: A Savory Solution to Save The Oceans

Seaweed: A Savory Solution to Save The Oceans

Eutrophication is a huge issue that is suffocating our oceans, and farming seaweed may be the key to saving them.

My mom often made kimbap, vegetables and rice wrapped in seaweed, for me to eat at school. Every year for my birthday, I ate miyeokguk, a seaweed soup. I would have dried and salted strips of seaweed as a midnight snack. Seaweed has always been a huge part of my upbringing and diet, so I did not think much of it and never considered that it would have the potential to save the planet —...
