Could King Kong ever evolve to exist? Could we simply scale up a gorilla? How and where could this giant ape develop? Join us as we explore the science behind the king of monsters!

This case study is a comparison between well-presented and poorly presented evidence. In this scenario, the expert is being asked about his investigation of a boat’s sinking rate. As part of the examination in chief, the expert is asked...

We’ve all heard that we should keep global climate change under 2 degrees of warming, but did you know that there are many places around the globe that have already surpassed that? Some places around the globe are experiencing extreme...

In part 2 of a 3 part discussion on fluid diffusion, Dr. Boyd explains and demonstrates the effect of temperature on diffusion. Minute 0:30 – Introduction Minute 0:41 – What you need Minute 0:54 – Explanation Minute 1:47 – Safety Minute...

A launch mishap led to the best experimental confirmation of gravitational redshift.

As global warming continues, we are going to continue seeing record droughts and many places are, simply, going to have to live with far less water. But, more specifically, it means we are going to need to innovate both how cities and...

Calculus is a branch of mathematics that deals with very small changes. Calculus consists of two main segments—differential calculus and integral calculus. Differential calculus primarily deals with the rate of change of things, while...

Hair resists decay even after death due to keratin, a structural protein. The structure and chemical composition of keratin make it difficult for organisms to break it down. Hair outlasts most other soft tissues due to the insoluble and...

The lymphatic system consists of a complex network of lymphatic vessels, glands or nodes, and organs, such as the spleen and thymus, extending throughout the body. Through it flows a fluid called lymph. The lymphatic system has three...

Measuring actual temperature consists of recording the air temperature from a thermometer that has been kept inside a Stevenson screen or by using any other appropriate instrument. “Feels like temperature,†on the other hand, is a...

Babies are cute because of their face structure and their sounds. Adult brains find the faces features of babies' faces cute. This signature cute baby face is called Kindchenschema (or baby scheme in English). Our brains seemed to be...
