Did you know that the human body literally glows? It emits a visible light in extremely small quantities at levels that rise and fall within the day. According to past research, the body emits visible light 1,000 times less intense than the levels which can be seen with the naked eye. In fact, almost all living creatures emit very weak light!

Scientists in Japan employed extraordinarily sensitive cameras capable of detecting single photons to learn more about this faint visible light. Five healthy male volunteers who are in their twenties were placed bare-chested in front of the cameras in complete darkness in light-tight rooms for twenty minutes every three hours.

The researchers found that the body glow rose and fell over the day, with its lowest point at around 10:00 in the morning and its peak at 4:00 PM, dropping gradually after that. These findings suggest that there is light emission linked to the body clock. This is happens due to how metabolic rhythms fluctuate over the course of the day.

Faces glowed more than the rest of the body and this might be because faces are more tanned since they get more exposure to sunlight.

Urine-powered cars, homes and personal electronic devices could be available in six months.

Using a nickel-based electrode, scientists can create large amounts of cheap hydrogen from urine that could be burned or used in fuel cells. One cow can provide enough energy to supply hot water for 19 houses.

One molecule of urea, a major component of urine, contains four atoms of hydrogen bonded to two atoms of nitrogen. If you place a special nickel electrode into a pool of urine and apply an electrical current, hydrogen gas is released.

A urine-powered vehicle could theoretically travel 90 miles per gallon.

When people find a wallet on the street, they either leave it, take it to a police station, find a way to contact the owner, and the worst thing is to keep it. What they do with it depends more on evolution that morality, according to scientists. They conducted an experiment on this and had hundreds of wallets put on the streets of Edinburgh. One of four photographs was inserted behind a clear plastic window in each of the wallets, which showed a smiling baby, a happy family, an elderly couple or a cute puppy. Some wallets had no image and some had charity papers inside.

The study found that people were far more likely to send the wallet back when faced with the photograph of the baby. Those wallets had the highest return rate, with 88 percent being sent back. Next came the wallets with the photograph of a puppy, the family and the elderly couple with 53, 48 and 28 percent respectively. The charity card and control wallets had the lowest return rates with only 20 and 15 percent.

Cocktail carrots or “baby” carrots that are bought in the supermarket are made using the larger crooked or deformed carrots which are put through a machine that cuts and shapes them into cocktail carrots.

You might have known that already, or you may have found out about it just now. What you might not know, though, is that once the carrots are cut and shaped into cocktail carrots, they are dipped in a solution of water and chlorine in order to preserve them!

When a baby carrot turns white, which is also referred to as “white blushing,” this causes the bags of carrots to be pulled from the shelf and thrown away. To prevent this consumer waste, the carrots are dipped in chlorine to prevent the white blushing from happening.

Chlorine is a very popular carcinogen and organic growers use a citrus based, nontoxic solution called Citrox instead.

According to a study, people with low-self esteem felt worse after repeating positive statements about themselves. They were asked to say phrases such as “I am a lovable person.” Researchers found out that saying things like these only helped people with high self-esteem.

The researchers asked people with both high and low self-esteem to say the same statement and they measured the participants’ moods and feelings about themselves. In the low self-esteem group, those who repeated the mantra felt worse after while those with high self-esteem felt better after.

Paradoxically, those with low self-esteem were in a better mood when they were allowed to have negative thoughts compared to the time when they were asked to focus exclusively on affirmative things. The researchers suggest that overly positive praise and unreasonably positive self-statements like “I accept myself completely,” can provoke contradictory thoughts in individuals with low self-esteem.

Such negative thoughts can then overwhelm the positive ones.
