The human brain weighs approximately 3.0 pounds. Human skin (all three layers) weighs approximately 20 pounds, intestines 7.5 pounds (large intestine: 4.0 lbs., small intestine: 3.5 lbs.), lungs 5 pounds (2.5 lbs. each), the liver 3.2 pounds, and the heart 0.6 pounds. Déjà vu (French for “already seen”) has never been fully explained, though some scientists believe that a neurological glitch causes an experience to be registered in the memory before reaching consciousness. The brain takes the longest of any organ to develop and goes through more changes than any other organ. A UCLA study found that both Caucasians and African Americans have similar brain activity when seeing photographs of African Americans. Both races showed more activity in the amygdala, an area of the brain associated with alarm, when shown expressionless photographs of African Americans than when they were shown expressionless photographs of Caucasians. What appears as random bursts of light when people h...

In today's culture, body art and piercings are a popular form of self-expression. Tattoos in particular are a common way of displaying your individuality. Because they are permanent, however, a lot of consideration should go into the decision to get a tattoo. The first question you may have is whether or not a tattoo will have a harmful effect on your skin. The process does involve, of course, needles and ink. The tattoo itself, once healed, is not bad for your skin. Issues arise, in fact, when complications occur during the healing process. A tattoo is essentially a series of punctures that insert dye into different levels of the skin, so it is by nature an invasive process. When done correctly and in a sterile environment, complications are uncommon, and the only immediate discomforts may be bleeding or pain. It's important to keep potential complications in mind, however. One potential risk is a bacterial infection at the tattoo site. Symptoms of this include r...

Wartime diseases such as scurvy and rickets are on the rise among British children because their junk food diets are worse than during rationing, doctors have warned. Health chiefs said a the resurgence of such disease is being caused by parents' reliance on takeaways and microwave meals to feed their children. Dr Mark Temple, chairman of the British Medical Association's public health medicine committee, warned: "Food standards in the UK are worse now that they were during the rationing during the war." Dr Temple said it was a "great tragedy" that children’s diets today are as unhealthy as the wartime diet. He added: "That's a strong indictment on the food industry. Obesity is a major health threat and we ought to be doing something about it." Dr Temple spoke out after a rise in the "old-fashioned wartime" illnesses in the former coal and steel areas of the Welsh valleys. Dietician Sioned Quirke, who wor...

The computer mouse as we know it today was invented and developed by Douglas Englebart during the 60's and was patented on November 17, 1970. While creating the mouse, Douglas was working at the Stanford Research Institute, a think tank sponsored by Stanford University, and originally referred to the mouse as a "X-Y Position Indicator for a Display System." This mouse was first used with the Xerox Alto computer system in 1973. However, because of its lack of success the first widely used mouse is credited to being the mouse found on the Apple Lisa computer. Today, the mouse is now found and used on every computer. The picture to the right was taken by Maracin Wichary at the New Mexico Museum of Natural History and Science, and is an example of what the first computer mouse looked like. As can be seen by the picture, the mouse was much larger than today's mouse, square, and had a small button in the top right corner.

A rigorous exercise regimen makes us all feel good but it is difficult to make time for it, Arslan  sohail suggests quick and easy ways to stay fit at work Exercising at work seems impossible. While we find it difficult to keep our hands off that packet of chips lying on our desks, the rest of us make frequent visits to the canteen to admire the spicy and tangy nibbles. It is okay to pander to your favourite food sometimes as long as you manage to burn those extra calories. So, how do you stay active and fit at work? To be fit, one has to be mentally and physically agile along with a lot of energy and a positive frame of mind. "Fitness comes with a combination of willpower and determination.

Activities such as bending down to pull out a file, stretching, walking up to your colleagues to deliver or receive messages or documents rather than using e-mails, getting up and fetching yourself a cup of coffee/ tea and...

2D or 3D? Drawing or sculpture? These dichotomies break down as you build up a physical model using a traditionally two-dimensional technique, tracing lines in the air that harden in real time to form objects.

I'm not given for answers like 'the organs shut down,' or 'our body stops producing genes.' I'm telling you why that happens. We have the ability to stay alive forever by having our cells replacing themselves all the time. So why does it stop? The reason behind this natural phenomenon is that our cells are predestined to death however these dead cells are also replaced by new cells which are the exact copy of previous cells. This process is under the control of genetic information stored in our cells in the form of DNA (genetic material).  When the cell divides this genetic material (DNA) also divides and produces the copies, which are exactly same as that of original DNA. This process usually provides the integrated copies however there are some factors, which disturbed the integration, and results in various malfunctions. These factors are responsible for producing mutations, which causes changes in the genetic material, which ultimately result...
