Unusual Apple spotted by Ken Morrish

The chances of getting an apple like this are a million to one. It’s thought to be a random genetic mutation. The Apple was found in the orchard of a man named Ken Morrish, where he's grown apples for 45 years. The man was picking apples in his garden for a family member when he spotted the unusual apple.

The red side of the apple is said to taste sweeter than the green side does. The reason for this is thought to be that the red side has seen more sunshine during its growth. The discovery is extremely rare and intriguing. Mr. Morrish is getting constant requests from his neighbors to take pictures of the rare apple.

The World's Quietest room at Orfield Laboratories

Orfield Laboratories has a room in their South Minneapolis facilities that has held the Guinness World Record for 'World's Quietest Room' since 2004. The room is built with fiberglass acoustic wedges that are 3.3-foot thick, and it has double walls of insulated steel and one-foot thick concrete. This makes it so that the room can absorb 99.99% of outside sound.

The room is used by various companies to test the loudness of their products without any outside distractions or sounds. This is a really good way to test if your company's latest phone is too loud, for example. The downside is that the room can drive you crazy. The laboratory says that the longest someone's been able to stay in the room is 45-minutes. But why?

Your body adapts to the silence. Your ears start picking up your heartbeat, your stomach or your lungs to levels that they aren't used to. The lack of sound also messes with your sense of perception. This is because our inner ear helps reach balance through sound cues when you walk. They say that people who are in there for half an hour have to be in a chair.

A lion’s roar can be heard five miles away

A lion's roar is one of the loudest noises any animal on Earth can make. It is so loud that it can be heard over five miles away from the lion! Scientists have been doing research on the immense sound lion’s emit and have discovered that the reason its loud isn't because of lung capacity.

It's actually because they have an unusual set of vocal cords which allow them to produce a noise that is both hard and heavy at the same time, all with hardly using the respiratory system. These vocal cords contain two membranes which are covered in a peculiar layer of fat that allow the vocal cords to vibrate horizontally, magnifying the sound.

Lake Retba - Senegal's pink lake

Lake Retba or Lac Rose lies north of the Cap Vert peninsula of Senegal, north east of Dakar. Depending on the time of day, the lake changes colour from a light purple to a deep scarlet pink. The unusual colouring of the water is caused by harmless halophilic bacteria that thrive in the lake’s high-salinity environment. The color is particularly visible during the dry season.

"The strawberry colour is produced by salt-loving organism Dunaliella salina. They produce a red pigment that absorbs and uses the energy of sunlight to create more energy, turning the water pink," said Michael Danson, an expert in bacteria from Britain's Bath University.

Covering an area of about 3 sq km, the lake is located about 35km north-east of Senegal’s capital Dakar. Since the 1970s, local residents have been mining Lake Retba for its salt, which they use mainly to preserve fish. Waist-deep in water, the men scrape the bottom of the lake to harvest this universally useful mineral which they collect in baskets in their wooden canoes. The salt is then taken back to shore where it is sectioned into small mounds. Dotted along the lake’s shore, these pristine white hills of salt create an arresting contrast against the pink of the lake. In order to protect their skin from the extreme salinity of the water, the workers rub their skin with shea butter, produced from shea nuts obtained from the Shea nut tree.

Lakes like Retba and the Dead Sea, which have high salt, were once thought to be incompatible with life. The salt content is very high, as much as 40%, which is almost one and a half times higher than in the Dead Sea - three hundred and eighty grams per liter. Lake Retba is well known for having been the end point of the famed Dakar Rally, which has since been relocated to South America.
