Scents and Sensibility

We’ve got chemistry…literally! This is Sandra Tsing Loh with the Loh Down on Science. You’ve just clicked with a new friend. It’s easy to SEE why. You think alike, talk alike, even dress alike … but do you SMELL alike? Inbal Ravreby from the Weizmann Institute of Science tried to

Modern Alchemy

What if WE have the Midas Touch? This is Sandra Tsing Loh with the Loh Down on Science. Turning water into metal? Sounds like something from an alchemy book! PURE water is not metallic — because the molecule structure is too stable. But, with enough pressure, we could SQUEEZE water

Very Hungry Caterpillars

Munch munch munch… Someday I will be a beautiful butterfly! This is Sandra Tsing Loh with the Loh Down on Science. Caterpillars spend their days busily feasting, turning carbon-rich leaves into nitrogen-rich poo. This means less falling leaves and more caterpillar poop washing into nearby lakes. This can change the

Bumblebeer

Man pouring beer in a glass

Bees can sting, but can they make you…tipsy? This is Sandra Tsing Loh with the Loh Down on Science. Brewing beer is an age-old tradition, and it’s all thanks to YEAST. There are nearly two thousand kinds of yeast on Earth. But only two types are used to brew beer:

Let Them Eat Air

Cell converting some molecules into others

Can we make food out of thin air? This is Sandra Tsing Loh with the Loh Down on Science. Soil is full of microbes. These tiny organisms eat and break down other organisms. They also recycle nutrients. But in desolate places on earth, or even in space, what is there
