Consider for a moment how valuable it is that we have the ability to communicate with one another. Other animals communicate, too, but we still know very little about how their chatter translates. A recent study tried to solve a piece of this big puzzle by studying bats.
We know more about the surface of the moon than Earth’s oceans and we know even less about the human brain, but a recently published study from Cal Tech is helping us put together a few pieces of the huge puzzle that is the brain. How does the brain keep memories?
Production of food, like many daily needs of humans, has a ripple effect on a myriad of other things. Cattle ranches are a food-related industry linked to some pretty big chunks of land, along with the deforestation needed to facilitate their work. Scientists are working on meat alternatives to give consumers less environmentally stressful options.
Natural disasters can be incredibly dangerous to nearby populations, but some could even impact the entire planet. Some of Earth’s natural resources are so massive that they not only serve vital functions in the immediate area but have global impacts as well, like the Amazon rainforest in South America.
