Do We Sleep To Forget Irrelevant Memories? Some Scientists Certainly Think So!

Do We Sleep To Forget Irrelevant Memories? Some Scientists Certainly Think So!

Researchers have long maintained that we sleep to accomplish a neural or physiological function that cannot be completed when awake. Why else would higher animals waste a third of their lives sleeping when they could be doing more important things like looking after their families, working, or hunting? Some scientists believe sleeping helps recharge the body, while others think it is important for consolidating newly-formed memories. Now, there is new evidence which suggests that the purpose of sleep may be to forget some of the millions of new things we learn each day.

Finally! Smart Prescription Glasses That Adjust To Your Vision Automatically

As most people age, the crystalline lenses in their eyes start to stiffen and are unable to change shape as easily. As a result, objects in close range start to look blurry, forcing many middle-aged adults to carry reading glasses either around their necks or tucked away in a handbag. Those already suffering from nearsightedness, or myopia, a condition where distant objects appear blurry, have to depend on bifocals or, even worse, switch between two pairs of glasses. However, thanks to some Utah researchers there may finally be a solution — self-adjusting “smart” glasses.

On March 10, Professor Robert Kelly was doing what the expert on South Korea does regularly — discussing a political situation on live television with a BBC News reporter via Skype. In this case, the topic was South Korean President Park Guen-hye's unprecedented March 9th impeachment for committing “acts that violated the Constitution and laws.”

Rejoice! It's The First Day Of Spring And International Day Of Happiness!

Residents of the US East Coast still recovering from last week’s record snowstorms will be happy to know that today is not just the first day of spring, but also the International Day of Happiness.

Behold, The World's Most Dangerous Tree!

With its wide canopy of leaves, the majestic 50-feet tall manchineel tree that is native to the Caribbean, Florida, the northern coast of South America, Central America, and the Bahamas, looks particularly inviting, especially on a hot summer day. But you may be wise to heed the warning signs given that the deceptively innocuous tree holds the Guinness World Record for “the world’s most dangerous tree.”

Should The Nearly Submerged "Zealandia" Be Classified As A Continent?

If some geologists have their way, world maps will soon be altered to reflect an eighth continent. Dubbed “Zealandia,” the landmass that lies east of Australia covers 1.9 million mi2 (4.9 million km2), or an area larger than the Indian subcontinent. The only catch? Over 94 percent of it is submerged in the southwest Pacific Ocean, with just the islands of New Zealand and New Caledonia, visible above sea level.

Clever Ants Use Sponges And Paper To Transport Honey

The phrase “good things come in small packages” certainly appears to hold true when it comes to ants. The tiny creatures can survive floods by morphing into rafts, find their way home using an internalized GPS system, and even lift up to 20 times their body weight. In 2013, scientists discovered that the insects whose brains are smaller than a quarter of a small pin’s head could even use tools, a skill that was once believed to be the realm of “intelligent” species like humans, and a select number of animals. Now, researchers from the University of Szeged in Hungary have discovered that when given a choice, the clever insects even have the smarts to select the most efficient tool for the job.
