Frozen Chicago: What The Windy City Looks Like Under Ice, Thanks To The Polar Vortex (PHOTOS) With temperatures in Chicago hobbling above zero for the first time in 37 hours Tuesday afternoon, it appears some relief is finally within sight for the Windy City. But while "ChiBeria" will soon be a thing of the past, we'll still have some incredibly remarkable photos to show for the bitterly cold, icy, undeniably unpleasant series of days. Thanks for the memories, polar vortex. Hank Cain AP And here's what all that ice and cold tomfoolery looks like up close. (AP Photo/Andrew A. Nelles) AP (AP Photo/Andrew A.

Traditional medicine in China Traditional Chinese medicine (TCM) is an alternative medical practice drawn from traditional medicine in China.
It has been described as "fraught with pseudoscience", with the majority of its treatments having no logical mechanism of action.[1][2] Medicine in traditional China encompassed a range of sometimes competing health and healing practices, folk beliefs, literati theory and Confucian philosophy, herbal remedies, food, diet, exercise, medical specializations, and schools of thought.[3] In the early twentieth century, Chinese cultural and political modernizers worked to eliminate traditional practices as backward and unscientific.
Traditional practitioners then selected elements of philosophy and practice and organized them into what they called "Chinese medicine" (Zhongyi). The demand for traditional medicines in China has been a major generator of illegal wildlife smuggling, linked to the killing and smuggling of endangered animals.[10] History[edit] Human biology. Cell Biology. Human Cells have Electric Fields as Powerful as Lighting Bolts -A Galaxy Insight. Using newly developed voltage-sensitive nanoparticles, researchers have found that the previously unknown electric fields inside of cells are as strong, or stronger, as those produced in lightning bolts. Previously, it has only been possible to measure electric fields across cell membranes, not within the main bulk of cells, so scientists didn't even know cells had an internal electric field. This discovery is a surprising twist for cell researchers.
Scientists don't know what causes these incredibly strong fields or why they' are there. But now using new nanotools, such as voltage-sensitive dyes, they can start to measure them at least. University of Michigan researchers led by chemistry professor Raoul Kopelman encapsulated voltage-sensitive dyes in polymer spheres just 30 nanometers in diameter.
Kopelman has developed encapsulated voltage-sensitive dyes that aren't hydrophobic and can operate anywhere in the cell, rather than just in membranes. Posted by Rebecca Sato. Human. Humans began to practice sedentary agriculture about 12,000 years ago, domesticating plants and animals which allowed for the growth of civilization. Humans subsequently established various forms of government, religion, and culture around the world, unifying people within a region and leading to the development of states and empires. The rapid advancement of scientific and medical understanding in the 19th and 20th centuries led to the development of fuel-driven technologies and improved health, causing the human population to rise exponentially. By 2012 the global human population was estimated to be around 7 billion.[10][11] Etymology and definition In common usage, the word "human" generally refers to the only extant species of the genus Homo — anatomically and behaviorally modern Homo sapiens.
In scientific terms, the definition of "human" has changed with the discovery and study of the fossil ancestors of modern humans. History Evolution and range Evidence from molecular biology. Human Diet and Nutrition. Health: Nutrition. 18 June 2014Last updated at 16:26 The human body needs a balanced diet to deliver vital nutrients What's your idea of a perfect meal? Sushi? A large piece of cake followed by hot chocolate? Even if it satisfies your appetite, it's unlikely to fulfil all your nutritional needs. Cutting through the myriad of diet plans and faddish eating regimes, the human body needs a balanced, healthy eating plan to keep functioning properly. Grow and build Repair and heal Reproduce successfully Repel illnesses and infections Avoid weight-related health problems Eating a variety of foods can also reduce the risk of getting conditions including heart disease, stroke, some cancers, diabetes and osteoporosis.
The foods we need to eat can be divided into five separate groups. The reason we need a diet drawn from all of the groups is that they all deliver different, but vital, nutritional benefits to our bodies. Starchy foods, also known as carbohydrates, are where we get most of our energy from. The Nutrition Source.
