Facts about elephants


 Intelligence
Elephants are some of the most intelligent animals on Earth. Their brains weigh 5kg, much more than the brain of any other land animal. Their brains have more complex folds than all animals except whales, which is thought to be a major factor in their intellect. They commonly show grief, humor, compassion, cooperation, self-awareness, tool-use, playfulness, and excellent learning abilities. An elephant in Korea surprised its zoo keepers by independently learning to mimic the commands they gave it by verbalizing on the end of its trunk, successfully learning 8 words and their context. Elephants have a more developed hippocampus, a brain

Mass extinctions


Cretaceous-Tertiary Extinction
This is the most famous extinction event. After the Jurassic ended, dinosaurs continued to proliferate and evolve throughout the subsequent Cretaceous period. They specialized into the forms which are familiar to many children today. More importantly, it was only during the Cretaceous period that life finally recovered from the much earlier Ordovician-Silurian extinction. The number of species at last matched and then exceeded the number from the Ordovician period, over 300 million years prior, for the first time. The synapsids finally evolved into small, rodent-like creatures, which were the first true mammals. 65 million years ago, a huge meteorite impacted the earth at Chicxulub in modern Mexico, disrupting the atmosphere and causing severe global warming, in turn killing 75% of all species. This meteorite contained a high

Weird college courses


The Art of Walking
The Art of Walking might seem trivial to some, but not to Dr Ken Keffer, Professor of Modern Languages at Centre College, Kentucky. He conducts a class dedicated to the understanding of ‘intelligible and sensual design in inner and outer nature’,first expounded by Immanuel Kant.

Most powerful drug lords

Pablo Emilio Escobar Gaviria was the most notorious and violent drug lord of the Medellín Cartel. Escobar was killed by the Search Bloc, a group of Colombian police devoted to capturing Escobar, on a Colombian rooftop in 1993; by this time, the cartel had already been severely damaged.

Incredible medical treatments



 Leech Therapy
Medicinal leeches are now making a comeback in microsurgery. They provide an effective means to reduce blood coagulation, relieve venous pressure from pooling blood, and in reconstructive surgery to stimulate circulation in reattachment operations for organs with critical blood flow, such as eye lids, fingers, and ears. The therapeutic effect is not from the blood taken in the meal, but from the continued and steady bleeding from the wound left after the leech has detached. The most common complication from leech treatment is

Controversial flags


The Flag of the USA
Also called the Stars and Stripes, Old Glory, and The Star-Spangled Banner, the flag features fifty stars, representing the fifty states, and thirteen stripes, which represent the original thirteen colonies that rebelled against the British crown and became the first states in the Union.
The American flag is to some a symbol of the freedom, liberty and opportunity found in the USA, while to others it represents America’s military presence around the world or economic dominance. While it is not uncommon to see news footage of the American flag being burned in protest in the Middle East, it is also sometimes burnt in protest within the country. The United States Supreme Court has ruled that, due to the First Amendment to the United States Constitution, it is unconstitutional for a government (whether federal,

Whatchamacallits and their real names



Tenesmus
Use: “Can I please use your bathroom? I have a serious case of tenesmus.”
Tenesmus is the uncomfortable feeling one has when needing to poop. It also refers to the feeling of having not emptied the bowel fully or the need to strain to do so. To put it more simply, tenesmus is a distressing but ineffectual urge to evacuate the rectum or bladder. The word, appropriately, comes to us from the Greek “teinesmos” which means “to stretch” or “to strain”.
