> Pothole becomes China’s Spring Festival Gala hit



Pothole, a televised sketch that took aim at bureaucratic inaction, was a major hit during this year’s Spring Festival Gala show.


“It vividly depicts a ‘lying-flat’ cadre who lacks a sense of responsibility and disregards public grievances while looking for glorified excuses, such as the public’s ‘low awareness to prevent potential road risks’,” said CPC Central Commission for Discipline Inspection (CCDI), the country’s top anti-graft body.


CCDI went on to say that civil servants who “lie flat” could obviously hurt society. “As Party members and civil servants, we need to establish and practice a correct political achievement value, get to know the sufferings of the masses, and be proud of serving the people,” it said.


> The truth about canning




During the mid-19th century, canned food became a status symbol among middle-class households in Europe, being something of a frivolous novelty.


Increasing mechanization of the canning process, coupled with a huge increase in urban populations across Europe, resulted in a rising demand for canned food.


A number of inventions and improvements followed, and by the 1860s, smaller machine-made steel cans were possible, and the time to cook food in sealed cans were reduced from around six hours to 30 minutes.

许多的发明和改进随之而来。到 1860 年代,小机器制造的钢罐也投入使用,而加工密封罐装食物的时间从大约六个小时减少到三十分钟。

To prevent the food from being spoiled before and during containment, a number of methods are used: pasteurization, boiling (and other applications of high temperature over a period of time), refrigeration, freezing, drying, vacuum treatment, antimicrobial agents that are natural to the recipe of the foods being preserved, a sufficient dose of ionizing radiation, submersion in a strong saline solution, acid, base, osmotically extreme (for example very sugary) or other microbially challenging environments.


Other than sterilization, no method is perfectly dependable as a preservative. For example, the spores of the micro-organism Clostridium botulinum (which causes botulism) can be eliminated only at temperatures above the boiling point of water.
