From Learning English, this is the Technology Report.
There are increasing calls for lawmakers to reconsider copyright laws that protect the owners of 3-D printing designs. But there is also concern that extensive laws could suppress new ideas. 3-D printers have spread from scientific labs to industrial workshops to private homes. And prices of 3-D printers continue to drop.
Designers demonstrate a large number of different machines at 3-D print shows. There are models that can produce complex copies of human organs. There are less costly 3-D printers that make toys for children or parts for home electrical devices.
One German automaker recently demonstrated an example of a car structure printed in one piece. And a Chinese manufacturer advertised a house created in a 3-D printer.
With the help of computer, almost anyone can print exact copies of many kinds of objects. But they also violate the law in doing so.
Julie Samuels is a lawyer with the civil liberties group, Electronic Frontier Foundation. She says people should be careful about what they create when using 3-D printers.
If a certain design that you want to print is covered by copyright, then if you print that you are infringing, arguably, someones copyright, said Julie Samuels.
But 3-D companies are concerned about passing more restrictive copyright protection laws. They think these laws could place bans on the rights of citizens. They also believe restrictive copyright laws could suppress technological invention.

Punctuality means observing regular or appointed time. A man who gets up at seven o'clock every morning is punctual. A man who has promised to call on a friend at five o'clock in the afternoon and actually does so at that hour is also punctual.
Punctuality is a good habit, and unpunctuality is a bad one. A few minutes delay may not be a serious matter, but it may have bad results. Getting up five minutes later than usual may upset the plan of the day. Calling on a friend five minutes later than the appointed time may cause him some unexpected trouble. Moreover, habitual unpunctuality leads to indolence and even failure in life. One delay after another makes a man unable to trust himself. It also proves him to be untrustworthy.
Those who are unpunctual should try their best to get rid of their bad habit. In doing this, they should avoid making any kind of exception. They should never say to themselves:"A few minutes delay does not matter this time. I shall never be unpunctual again." Those who think in this way will find excuses for delay from time to time, and will at least give up the attempt to cultivate the good habit.
Like all other good habits, punctuality becomes second nature with those who have duly cultivated it.

A lot of people think growth in Africa, they think the only driven by mineral wealth or oil-exporting countries, but we find now the report that even countries that are not resource rich are still growing effectively. This is mainly because of their agricultural sector but also growth in services [including tourism] and a little in manufacturing, said Lusigi.
The report says Africas top foreign trade partner is Europe. About 40 percent of African trade is with European nations. 25 percent is with Asian countries and about 12 percent is with North America.

Some herbs and spices are valued for their taste. They help to sharpen the taste of many foods. Others are chosen for their smell. Still others were used traditionally for health reasons.
When people think of improving their diet, they often talk about eating more fruits and vegetables. Others want to eat more fish and less red meat, in addition to reducing the amount of food they eat. But, they can improve their diets even more with just a simple addition.
American researchers have found that a diet rich in spices can help reduce the harmful effects of eating high fat meals. Researchers at Pennsylvania State University reported the findings.
Penn State Associate Professor Sheila West led an investigation of the health effects of a spice-rich diet. Her team knew that a high-fat meal produces high levels of triglycerides, a kind of fat, in the blood.
She said, If this happens too frequently, or if triglyceride levels are raised too much, your risk of heart disease is increased. We found that adding spices to a high-fat meal reduced triglyceride response by about 30 percent, compared to a similar meal with no spices added.
