In this week's lit update, we are discussing the recently discovered "Ferroelectric Nematic Liquid Crystals" and in this work, the researchers have uncovered ways for types of these chiral liquid crystals to change colors with the use of an electric field! Neat!

Did you know that cooking with oil lead to thin oil film deposits on indoor surfaces? These oily deposits can attract water, which can cause bacterial growth and chemical reactions! Tune in to learn what scientists from University of San Diego and University of Texas learned about how the chemical composition of the oil deposits affect how water films form on glass!

Excessive bleeding during surgery or trauma must be stopped immediately before it becomes deadly. In this lit update, scientists from Nankai University developed a chitosan, derived from shrimp shells, microchannelled sponge-like hemostats using 3D printing that can stop bleeding within 2 minutes!

In today's awesome lit update, we talk about lithium-air-breathing batteries! (LABs!) Wait, what?!

Now these lithium air-breathing batteries, often known as LABs or LOBs as in Lithium-Oxygen Batteries don’t actually have lungs! Their operation is based on the metal-air interface to function.

We constantly hear that personalized medicine is the medicine of the future but when will this become a reality? Researchers in this field are constantly making progress and one of the most recent developments is from researchers in Israel and China who made wearable microneedle sensors for continuous sodium monitoring!
