10 Things You Didn't Know About You

The human body is a great, sweaty, fluid-filled machine, moving and mixing chemicals with precision and coordination, making everything from memories to mucus. Here we explore some of the complex, beautiful or just plain gross mysteries of how you function.

10. Your Stomach Secretes Corrosive Acid

 There's one dangerous liquid no airport security can confiscate from you: It's in your gut. Your stomach cells secrete hydrochloric acid, a corrosive compound used to treat metals in the industrial world. It can pickle steel, but mucous lining the stomach wall keeps this poisonous liquid safely in the digestive system, breaking down lunch.
                                       09. Body Position Affects Your Memory

Can't remember your anniversary, hubby? Try getting down on one knee. Memories are highly embodied in our senses. A scent or sound may evoke a distant episode from one's childhood. The connections can be obvious (a bicycle bell makes you remember your old paper route) or inscrutable. A recent study helps decipher some of this embodiment. An article in the January 2007 issue of Cognition reports that episodes from your past are remembered faster and better while in a body position similar to the pose struck during the event.

08. Bones Break (Down) to Balance Minerals

 In addition to supporting the bag of organs and muscles that is our body, bones help regulate our calcium levels. Bones contain both phosphorus and calcium, the latter of which is needed by muscles and nerves. If the element is in short supply, certain hormones will cause bones to break downeupping calcium levels in the bodyeuntil the appropriate extracellular concentration is reached.

07. Much of a Meal is Food For Thought

 Though it makes up only 2 percent of our total body weight, the brain demands 20 percent of the body's oxygen and calories. To keep our noggin well-stocked with resources, three major cerebral arteries are constantly pumping in oxygen. A blockage or break in one of them starves brain cells of the energy they require to function, impairing the functions controlled by that region. This is a stroke.

06. Thousands of Eggs Unused by Ovaries

 When a woman reaches her late 40s or early 50s, the monthly menstrual cycle that controls her hormone levels and readies ova for insemination ceases. Her ovaries have been producing less and less estrogen, inciting physical and emotional changes across her body. Her underdeveloped egg follicles begin to fail to release ova as regularly as before. The average adolescent girl has 34,000 underdeveloped egg follicles, although only 350 or so mature during her life (at the rate of about one per month). The unused egg follicles then deteriorate. With no potential pregnancy on the horizon, the brain can stop managing the release of ova.

05. Puberty Reshapes Brain Structure, Makes for Missed Curfews

 We know that hormone-fueled changes in the body are necessary to encourage growth and ready the body for reproduction. But why is adolescence so emotionally unpleasant? Hormones like testosterone actually influence the development of neurons in the brain, and the changes made to brain structure have many behavioral consequences. Expect emotional awkwardness, apathy and poor decision-making skills as regions in the frontal cortex mature.

04. Cell Hairs Move Mucus

Most cells in our bodies sport hair-like organelles called cilia that help out with a variety of functions, from digestion to hearing. In the nose, cilia help to drain mucus from the nasal cavity down to the throat. Cold weather slows down the draining process, causing a mucus backup that can leave you with snotty sleeves. Swollen nasal membranes or condensation can also cause a stuffed schnozzle.

03. Big Brains Cause Cramped Mouths

 Evolution isn't perfect. If it were, we might have wings instead of wisdom teeth. Sometimes useless features stick around in a species simply because they're not doing much harm. But wisdom teeth weren't always a cash crop for oral surgeons. Long ago, they served as a useful third set of meat-mashing molars. But as our brains grew our jawbone structure changed, leaving us with expensively overcrowded mouths.

02. The World Laughs with You

Just as watching someone yawn can induce the behavior in yourself, recent evidence suggests that laughter is a social cue for mimicry. Hearing a laugh actually stimulates the brain region associated with facial movements. Mimicry plays an important role in social interaction. Cues like sneezing, laughing, crying and yawning may be ways of creating strong social bonds within a group.
                                                                
                                             01. Your Skin Has Four Colors

All skin, without coloring, would appear creamy white. Near-surface blood vessels add a blush of red. A yellow pigment also tints the canvas. Lastly, sepia-toned melanin, created in response to ultraviolet rays, appears black in large amounts. These four hues mix in different proportions to create the skin colors of all the peoples of Earth.

The Seville's Solar Power Tower — Spain

The PS10 Solar Power Plant is the world's first commercial concentrating solar power tower operating near Seville, in Andalusia, Spain. The 11 megawatt (MW) solar power tower produces electricity with 624 large movable mirrors called heliostats. It took four years to build and so far cost €35 million (US$46 million). PS10 produces about 23,400 megawatt-hours (MW·h) per year, for which it receives €271 (US$360) per MW·h under its power purchase agreement, equating to a revenue of €6.3 million per year.

 The mirrors were delivered by Abengoa, the solar receiver was designed and built by Tecnical-Tecnicas Reunidas, a Spanish engineering company; and the Solar Tower was designed and built by ALTAC, another Spanish engineering and construction company. Each of the mirrors has a surface measuring 120 m² (1,292 square feet) that concentrates the sun's rays to the top of a 115 meter (377 ft) high, 40-story tower where a solar receiver and a steam turbine are located. The turbine drives a generator, producing electricity. The PS10 is located 20 km west of Seville (which receives at least nine hours of sunshine 320 days per year, with 15 hours per day in mid summer). The solar receiver at the top of the tower produces saturated steam at 275 °C. The energy conversion efficiency is approximately 17%.

Yangshuo County — China

 Yangshuo County is a county in Guilin, Guangxi Province, China. Its seat is located in Yangshuo Town. Surrounded by karst peaks and bordered on one side by the Li River it is easily accessible by bus or by boat from nearby Guilin. In the 1980s, the town became popular with foreign backpackers, and by the late 1990s packaged tourists began arriving in greater numbers. At that time, domestic tourism represented only a small fraction of the tourists but by 2005 domestic tourists outnumbered foreign tourists by a great margin. Today, the town has become a resort destination for both domestic and foreign travelers.

 Yangshuo is a very scenic, small county and city surrounded by many karst mountains and beautiful scenery near Guilin, Guangxi. It is very popular among tourists. Yangshuo is popular for its incredible karst scenery, beautiful mountains, rivers, caves, and temples as well as its laid back cafes and bars. However, as a result, there is no shortage of mainland Chinese tourists, ex-pats and other foreigners.

Yangshuo is not a typical Chinese town and does not have the big-city feel as in most other Chinese cities. That means it is relatively air and noise pollution free, (provided you get away from major roadways), very clean (by Chinese standards) and does not usually suffer from endless massive traffic chaos. It is much more like a vacation town, with wonderful restaurants and shops and again quite developed by mainland Chinese standards. Yangshuo has a reputation as a foreigners' village in Southern China and is a major stop on the trail of many independent travellers. It is also a nice place to stop and explore the local countryside by bike or even try your hand on the world class rock-climbing sites. 

Futuristic Cultural Complex in Changsha — China

Zaha Hadid Architects (ZHA) have unveiled an ambitious cultural complex, which began to take shape in October after the project broke ground in the heart of Changsha, China. In true Hadid-fashion, the Changsha Meixihu International Culture & Arts Center defines itself by extreme sinuous curves that radiate from each of the three independent structures and links them to a pedestrianized landscape that offers a “strong urban experience”, forming what they hope to be a global destination for theater and art.

The International Culture & Arts Centre embodies a unique variety of civic nodes and spaces: A Grand Theatre, a Contemporary Art Museum, a Multipurpose Hall and supporting facilities. The central plaza is generated by the relative position of these separate buildings and offers a strong urban experience whereby the flow of pedestrian visitors that come from all sides of the site intersect and meet. In parallel it also stretches outwards to the neighboring streets with unfettered and phenomenal views across Meixi lake with access towards Festival Island.

The Grand Theatre is the focal point of the Changsha International Culture & Arts Centre. It is the largest performance venue in the city with a total capacity of 1800 seats. Designed to host world-standard performances the building contains will contain all the necessary front of house functions, such as lobbies, cloakrooms, bars, restaurants, and VIP hospitality, as well as the required ancillary functions, such as administration, rehearsal rooms, backstage logistics, dressing and make-up rooms, and wardrobe.

The Museum’s composition of three fluid petals around its internal central atrium, juxtaposes of the various patchworks of gallery spaces in a truly seamless fashion. With outward views and balconies to its exteriors, it aims to engage the site’s unique location and surrounding views into some of its gallery spaces. An external plaza which faces Meixi Lake Road allows for outdoor sculptures, exhibitions and events to be extended to an expansive outdoor space.

 The Small Theatre (Multipurpose Hall) is characterized by its flexibility. With a maximum capacity of 500 seats, it can be adapted and transformed to different configurations. It can therefore accommodate a broad range of functions and shows that span from banquets and commercial events to small plays, fashion shows and music. A commercial attraction, this venue shares seamless public access to retail areas and restaurant facilities, which are seated in an open and gently sunken courtyard linking visitors to and from the basement level.

Although these civic institutions are uniquely defined and separate, they supply each other in all respects within its setting with plazas offering visitors a tapestry-like sequence of urban ambiances that relate to the different institutions, inject the site with urban vitality. The working hours of the different venues also overlap to ensure continuity during the full 24 hour cycle; Operated during the evening, the Grand Theatre becomes active as the Museum begins to conclude its day- time operations whilst the Small theatre and retail/restaurants would be commercially available day and night. In this regard, they benefit from each other’s vicinity, ensuring that the site is lively 24 hours a day. This dynamic composition further establishes a powerful relationship with its surroundings, which confers monumentality to the ensemble.

Embodying values of functionality, elegance and innovation, the Changsha Meixi Lake International Culture & Arts Center aims to become the new cultural and civic node for the city of Changsha, and well as global cultural destination.

Auto Aerobics by Chris Labrooy

British artist and designer Chris Labrooy remade classic American car fleet in the surreal with the option of levitation. The inspiration for the project began Chris cars standing along the sidewalks. Using photography, illustrative techniques and a wealth of 3D tools and tricks, he’s created these startling images of inter-connected cars direct from his computer screen. The author apparently wanted some free street and using it for the usual set of 3D-Tool "parked" cars in the air, a pre-assembled one course like puzzle.
