Sex, drugs, rocks, gold, murder, war, mass poisonings, the deaths of Napoleon, Tchaikovsky, Mozart, and others are all linked by one element – arsenic! Arsenic has been around since the beginning of time and the word has become a metaphor for poison with associated shock value.

But nowadays Japanese rice-based drinks are becoming a central part of Western diets, such as vegan diets. However, the levels of toxic inorganic arsenic contained in these types of drinks could, in fact, be cause for concern.

High levels of arsenic have recently been found in rice-based food. Now, researchers have found that some drinks and syrups contain high levels of arsenic too. “The rice-derived products we investigated are consumed by millions of people in Japan on a regular basis, and are increasingly becoming an important part of the diet of health conscious consumers in Western countries, ” says Signes-Pastor. However, regularly including these types of drinks in the diet could add as much as 23% of the daily tolerance level of arsenic.

Although in isolation this may not seem of massive concern, for people already taking high levels of arsenic from rice and sea-weed based products this could mean exceeding maximum daily tolerance levels.

Similar products derived from barley or millet contain much lower levels of arsenic and could be used as an alternative to the rice based drinks. This could be particularly important for people who already eat a lot of rice and sea-weed products.

The experiments showed that regulations for inorganic arsenic in foodstuffs and non-water drinks should be re-examined. Regulations for arsenic in foodstuffs and non-water drinks may lead to a reduction in the incidence of arsenic-attributable diseases, including various cancers.

One day a professor was discussing a particularly complicated physics concept. A pre-med student rudely interrupted to ask, “Why do we have to learn this pointless information. ”

“To save lives, ” the professor responded quickly and continued the lecture.

A few minutes later, the same student spoke up again. “So how does physics save lives? ” he persisted.

“It keeps the ignoramuses like you out of medical school, ” replied the professor.

Two things are infinite: the universe and human stupidity; and I’m not sure about the universe. (Albert Einstein)

French physicist Ampere (1775-1836) had two cats, one big and a one small, and he loved them very much. But when the door was closed cats couldn’t enter or exit the room. So Ampere ordered two holes to be made in his door: one big for the big cat, and one small for the small cat.

What’s the difference between mechanical engineers and civil engineers?

Mechanical engineers build weapons. Civil engineers build targets.

Many dead animals in the past changed to fossils while others preferred to be oil.

Living on Earth may be expensive, but it includes an annual free trip around the Sun.

Q: How many programmers does it take to change
