Batty Idea

Holy biodiversity, Batman! This is Sandra Tsing Loh with the Loh Down on Science. Ninety percent of plants and animals in Madagascar are found nowhere else! Sadly, insect outbreaks threaten this amazing biodiversity. When they chomp down local crops, farmers are forced to compensate for the loss with field expansion!

Organic Pollution

Forest meadows, fresh flowers… tail pipe exhaust? This is Sandra Tsing Loh with the Loh Down on Science. Secondary organic aerosols–gah! These tiny particles are a class of chemicals that form the air around us. As natural and industrial gas emissions interact with sunlight, the resulting particles reflect or absorb

Deep Dive

What menacing secrets lurk in the depths of the ocean? This is Sandra Tsing Loh with the Loh Down on Science,saying…one word: “Plastics!” Plastics have been invading our oceans for years.

Bite Me

To live or to die…? Depends on your. . . teeth? This is Sandra Tsing Loh with the Loh Down on Science. One hundred and eighty million years ago, gigantic marine reptiles ruled the seas. Then, water levels began rising… dramatically! Not all seafaring reptiles could adapt. So, who survived

Thinking Plants

Can plants think? Would you believe… yes? This is Sandra Tsing Loh with the Loh Down on Science. Consider barberry, a European shrub. It produces bean-sized fruits, each with one or two seeds. Its biggest threat is a tiny fruit fly. The fly injects its eggs into one of the

Relephant Factors

What makes an elephant pack its trunk. . . and leave? This is Sandra Tsing Loh with the Loh Down on Science. Elephant societies are matriarchal. Mothers and grandmothers lead the way. Sadly, older females are often targeted for their tusks. This leaves their family orphaned! So what happens when
