The idea that people might be chosen or rejected for jobs on the basis of their genes disturbs many. Such (1) may, however, be a step (2) , thanks to work just published in Current Biology by Derk-Jan Dijk and his colleagues at the University of Surrey, in England. Dr. Dijk studies the biology of time-keeping—in particular of the part of the internal body-clock that (3) people to sleep and wakes them up. One of the genes involved in (4) this clock is known as PER3 and (5) in two forms. Dr. Dijk’s work (6) that one of these forms is more conducive to night-shift work than the other.
The two forms of PER3 (7) into two slightly different proteins, one of which is longer than the other. (8) work by this group showed that people with two short versions of the gene are more likely to be "owls", (9) to get up late and go to bed late. "Larks"— (10) , early

Heart {{/B}}
1. Researchers say they have developed a simple test that can tell if a person with heart disease is likely to suffer a heart attack. The test measures levels of a protein in the blood. The researchers say people with high levels of this protein are at high risk of heart attack, heart failure or stroke. 2. Kirsten Bibbins-Domingo of the University of California in San Francisco led the team. For about four years, they studied almost one thousand patients with heart disease. The researchers tested the heart disease patients for a protein called NT-proBNP. Patients with the highest levels were nearly eight times more likely than those with the lowest levels to have a heart attack, heart failure or stroke. 3.

It wasn’’t an easy decision, but we’’ re been asking for a decent wage for years. Now at last people are beginning to listen to us because we work day and night to keep this country alive and what do we get 200 dollars a week. That’’ s not enough to raise a family at today’’ s prices. Inflation this year was 32 percent. We’’ re only asking for a 25 percent increase in our wages. 250 dollars a week, that’’ s all. It’’ s a pity so many people have to be inconvenienced by our strike. But please don’’ t blame us. Blame the government. That’’ s what you should blame. Blame the government for refusing our claim.
Mr. Tom Brown:
It’’ s totally unreasonable to demand so much money when we are trying desperately to control inflation. If wages go up, so do prices. If we gave in to the electricity workers, all the other unions would want more, with the inevitable result that the crisis would become uncontrollable. What were trying to impress upon everybody is that inflatio

Nevertheless, the skillet (长柄平底煎锅) is about our handiest and most useful piece of kitchen equipment. Strong woodcutters and others engaged in active labor requiring 4,000 calories per day or more will take approximately one-third of their rations prepared in this fashion. Meat, eggs, and French toast cooked in this way are served in millions of homes daily. Apparently the consumers are not beset with more signs of indigestion than afflicted by those who insist upon broiling, roasting, or boiling. Some years ago one of our most eminent physiologists investigated the digestibility of fried potatoes. He found that the pan variety was more easily broken down for assimilation than when deep fat was employed. The latter, however, dissolved within the alimentary tract (消化道) more readily than the boiled type. Furthermore, he learned, by watching the progress of the contents of the stomach by means of the fluoroscope (荧光检查仪), t
