Ebbinghaus illusion
The Ebbinghaus illusion is an optical illusion that occurs when a stimulus appears larger than the size of its surroundings. Its appearance will depend on the size of the stimulus and what the surrounding objects perceive. The flash-lag effect which causes the objects to look similar later in time confirms size perception. Participants were shown two sets each of four identical surrounding discs at different times, depending on their position on the retina. It was evident that the size of the central discs on one side of the retina changed significantly, creating a flash-lag effect.

Have you ever wondered what amount of trash is generated each day worldwide?
According to the United Nations, the average person produces over 2.5 pounds of daily waste.That adds up to over 25 billion pounds of garbage per year!
The majority of this garbage ends up in incinerators or landfills. But what happens when the dumpsters become full? Most of that trash is shipped out of the country. It is then shipped out and dumped in other countries. This pollutes the ecosystems. But now we know, thanks to one man. His name is Mike Sexton. He runs a company called Waste Watchers.He spends his days watching the movements of trucks transporting trash across North America. He then reports back about what happens next.
Sexton said he enjoys his job. CNN interviewed Sexton and said that he has a lot of fun. "You know, we see these big rigs come through town, and we'll follow them. "Sexton began following truckers almost 20 year ago.
He stated, "I just fell in Love with It."
He loved the story of the driver who pulled into an abandoned gas station near Los Angeles. Sexton remembered, "The man was looking for somewhere to put the load." "He saw the building as he drove down the road. He stopped and pulled up, then he went inside. "There were two huge roll-off containers there filled with stuff. The man took all the stuff out and filled up his truck with more. He then looked around and decided to load everything. There were old tires and rags, furniture pieces, mattresses, mattresses and boxes. It was a complete mess. But it had been cleaned before he arrived. There wasn't any trash anywhere."
This begs the question: Why? It's because this area used to be a recycle center. People would drive from all over the country to recycle their trash. "They'd bring their household items and take them to this building," Sexton explained.And after they finished, they would leave the empty containers behind.
This could happen hundreds of time per week. This can happen hundreds of times a week.Eventually, the truck becomes so overloaded with junk that it stops running. The owner finally decides to stop using the truck.
But, this isn't the only problem that our planet is facing.
These tiny plastic particles make up the majority of the particles. Some end up in incinerators or landfills. Others get washed into rivers or oceans.And when they reach the ocean, they often end up in the stomachs of fish.
Experts warn us that we may soon face an international food shortage if things don't change. "If we keep going like we're going, we're not going to make it," one expert warned.But even though scientists agree that the world is headed toward disaster, most people don't seem worried.
What is the most secretive place in the world, and why?
It may surprise you to hear the answer. It could even make you uncomfortable, because it challenges how reality is perceived and lived. But there is a reason why this place exists. And it is not what you would expect.
The ancient Greeks called it the City of God. It was called the City of Destruction by the Bible.
It's also known as Kashi (Kashmir) in India. In Russia, it's called Novgorod.
But here in America, it goes by another name - The Town That Disappeared.
A small town in western New York State, with a population of 1,200, vanished without a trace. There were no bodies, cars or houses left behind, but a road sign that pointed to the former location was all that was left.
This tiny community disappeared without leaving any clues as to where it went or when. Some believe the earth swallowed them up. Others claim that a meteorite hit destroyed it. Some claim that it was destroyed by a meteorite strike. Others still believe it was stolen away by aliens.
Whatever happened, the residents of this once-thriving community are convinced that their town isn't gone forever. They had just relocated to another town.
A website is available to track the disappearance and recovery of Zugspitz, which was lost in the Great Depression.
So, where exactly did this town go? It's in Switzerland, actually!
The border of Austria and Germany is at Zugspitze. A huge lake, Lake Zugspitze, is located just beyond the summit.
It has always fascinated me that so many towns have disappeared, yet some still remain. What is the difference between some towns that disappear and others that survive? I decided to investigate.
I wanted more information about the mysterious disappearing of towns. What makes a town disappear? How can one place become extinct?
It turned out that there are many theories about disappearing towns. One theory suggests that a community disappears when all of its buildings are removed. Another theory says that the town just moves. A third theory holds that the town did not exist.
The fact is that hundreds of towns all over the world have been swept away by the ground, despite theories to the contrary. This video explores the history of these towns and examines their current state.
How does your brain control your body's functions?
The brain communicates with other organs to ensure their cooperation. The brain controls everything that happens in your body. It tells the stomach to digest food, and the lungs to breath air. It also tells your legs and arms to move.
Your brain is composed of billions and billions nerve cells, connected in groups called neurons. Action potentials, which are electrical signals sent by neurons to each other via axons, allow them to communicate with one another. Each neuron is covered by a cell membrane. Inside the membrane are channels that allow ions such as sodium and potassium to enter and leave the cell. Ion movement is what causes the neurons to fire.
When a neuron is activated, neurotransmitters release chemicals into the space between it and the next neuron. Neurotransmitters can bind to receptors at the second neuron. They open ions channels, allowing ions to move in and outside of the channel. In turn, the second neuron also fires.
Neurotransmitter releases occur when a presynaptic neurons receives an input from another neuron. The impulse travels along an synapse between the neurons. The transmitter binds to the receptors on the postsynaptic neural cell, which triggers the firing of that neuron.
Communication within the nervous system is possible thanks to neurotransmitters. They coordinate activity between the different parts of your brain.

Hollywood scandals that shocked all of the world
It's shocking to see someone make a name for themselves. It's even more frightening to see them fall from grace.
It is amazing to see how an industry handles its mistakes. Many celebrities have used alcohol and drugs in excess. Some even died young because of it.
It's worse when stars make public their problems, and then are ignored by everyone. We were there last week.
After a long and successful career, Heath Ledger finally succumbed to his demons. He took too many prescription pills and died shortly after.
His family and friends struggled to accept his passing, and the media had a field day bashing him publicly.
Heath was once considered one of the most talented actors working today. Two Academy Awards nominations were given to Heath for his role in Brokeback Mountain.
Heath did more than act. He also directed films including A Knight's Tale. Monster's Ball and Iron Man.
Hollywood loved Heath. However, he quickly grew too large. He started to use drugs and drink heavily. He eventually went to rehab and was clean.
After he had gotten sober, he decided to make amends. So he made a documentary called "Room 237," which chronicled the making of The Shining. It was supposed to hit theaters this year. However, it won't until next year.
Heath was unsuccessful in his attempts to get back into Hollywood. Heath was in fact arrested twice on drug charges.
Although we don't think Heath should be allowed to return to the showbiz, It would have been nice for him to have received some assistance before things spiraled outof control.
We hope Heath’s tale will be a wakeup call to anyone who may believe that they can still have all.
