Food picked up just a few seconds after being dropped is less likely to contain bacteria than if it is left for longer periods of time, according to the findings of research carried out at Aston University's School of Life and Health Sciences. The findings suggest there may be some scientific basis to the '5 second rule' --- the belief about it being fine to eat food that has only had contact with the floor for five seconds or less. Although people have long followed the 5 second rule, until now it was unclear whether it actually helped.

The study, undertaken by final year Biology students and led by Anthony Hilton, Professor of Microbiology at Aston University, monitored the transfer of the common bacteria from a variety of indoor floor types such as carpet, cement floor to toast, pasta, biscuit and a sticky sweet when contact was made from 3 to 30 seconds. The results showed that: Time is a significant factor in the transfer of bacteria from a floor surface to a piece of food; and the type of flooring the food has been dropped on has an effect, with bacteria least likely to transfer from carpeted surfaces and most likely to transfer from cement flooring surfaces to moist foods making contact for more than 5 seconds. Professor Hilton said: "Consuming food dropped on the floor still carries an infection risk as it very much depends on which bacteria are present on the floor at the time.”

The Aston team also carried out a survey of the number of people who employ the five-second rule. The survey showed that: 87% of people surveyed said they would eat food dropped on the floor, or already have done so. 55% of those that would, or have, eaten food dropped in the floor are women. 81% of the women who would eat food from the floor would follow the 5 second rule. Professor Hilton added: "Our study showed surprisingly that a large majority of people are happy to consume dropped food, with women the most likely to do so. But they are also more likely to follow the 5 second rule, which our research has shown to be much more than an old wives tail."

1. Eating food dropped on the floor still carries an infection risk because it relies on________ at that time.

A. the type of bacteria B. the carpet

C. the cement floor D. the surface of table

2.The passage is developed probably by __________.

A. time B. space C. contrast D. example

A. Satisfied B. Astonished

C. Puzzled D. Upset

4.What is the main idea of this passage?

A. The food which is dropped on the floor can be eaten safely.

B. The bacteria have no negative effect on the safety of food.

C. A research on the safety of food dropped on the floor is undertaken.

D. People surveyed in the research are willing to accept the idea.

Here’s something that might make you feel a little better the next time you have a serious case of hanger - you’re not being irrational or unreasonable, it’s just science.

The concept of being ‘hangry’ - angry because you’re hungry - comes up among ScienceAlert staff.But there’s nothing wrong with being hangry - there’s a scientific reason why having low blood sugar can make some people aggressive.

According to a study published earlier this year, blood sugar levels directly related to how married couples were likely to treat each other.Working with 107 couples over three weeks, the researchers, led by psychologist Brad Bushman from the Ohio State University in the US, found that when individuals experienced lower than usual blood sugar levels, they became increasingly aggressive and mean towards their significant others.

This was measured through the use of a good old-fashioned voodoo doll — the volunteers were each given one, along with 51 pins, to represent their spouse-a partner in marriage.Each person’s aggressive impulses(冲动)were then measured based on how many pins they stuck into their spouse-dolls every night throughout the experiment.

Aggression, on the other hand, was measured by volunteers blasting(炮轰)their spouse with a loud and unpleasant noise in the headphones they had to wear.

Turns out that the volunteers who experienced the lowest blood sugar levels stuck more pins into their voodoo dolls, and forced louder and longer blasts of noise on their spouses than those who had plenty of glucose(葡萄糖) in their system.

"People are often the most aggressive against the people to whom they are closest — intimate partners,” the researchers concluded."Intimate partner violence might be partly a result of poor self-control.Self-control of aggressive impulses requires energy, and much of this energy is provided by glucose from the food we eat."

As Susannah Locke explains at Vox, glucose is the only molecule(分子) that our brains will accept as fuel.This means, quite simply, that when we’re not producing enough glucose, our brains won’t function properly.It also means that we lack the energy we need to maintain self-control, which is why we’re more likely to hit or criticize others suddenly in an uncharacteristic manner when we haven’t eaten in a while.
