Nguy cơ rụng tóc sớm ở Gen của Đàn ông Ngắn Hói là điều không thể tránh khỏi ở nhiều người già, nhưng nó có thể là mối quan tâm đặc biệt đối với những người đàn ông ngắn. Một nghiên cứu mới cho thấy những con đực có tầm vóc ngắn có nguy cơ bị rụng tóc sớm, ngoài một số bệnh trạng khác. Nghiên cứu phân tích bộ gen của hơn 20.000 đàn ông, khoảng một nửa trong số họ đã hói đầu trước khi họ 50 tuổi. Một nửa số người tham gia không bị rụng tóc và đã được sử dụng để so sánh. Nghiên cứu bao gồm những người đàn ông đến từ Hoa Kỳ, Thụy Sĩ, Hà Lan, Đức, Anh, Hy Lạp và Úc. Các nhà nghiên cứu đã xác định được 63 thay đổi trong hệ gen của con người làm tăng nguy cơ hói đầu sớm. Và trong nhiều trường hợp, các vùng DNA chồng chéo với các gen cho tầm vóc ngắn.

The development of genetically modified (GM) plants and animals had led to a huge global controversy. Opponents say that GM “Frankenfoods” are a threat to our well-being, and proponents say that the risks are minimal. There is one aspect of the war over GM that is often overlooked. Anyone who wears a cotton shirt these days is using a GM crop. Cotton is the only major non-food GM crop at present, but others are coming.

GM cotton plants that are not food have not stopped the most passionate GM opponents from objecting. If GM cotton is grown in a field next to fields of non- GM cotton, they argue, then how to keep genes from being transferred from field to field. This danger, however, is not as compelling to the public as possible health hazards in food, so there is no great fury over GM cotton.

GM cotton seeds produce higher yields, and they do without the need for pesticides. Planting of GM cotton has increased fivefold since 1997; three-quarter of cotton in America, and over half in China, is now GM. Farmers like it because it increases their profits.

Other options for non-food GM include new variety of flowers with different colors or scents, tougher grasses for lawns, and plants designed to soak up pollutants from the soil. The paper industry provides another example of potential for GM to help produce better and cheaper products. Paper is made from pulp, and pulp is generally made from trees. Researchers in New Zealand and Chile have been working on insect-resistant pines, and a Japanese firm has combined carrot genes with tree genes to make them grow better in poor soil.

Another interesting case is that of tobacco. It is not food crop, but it is consumed, and GM tobacco plants with both more and less nicotine have been created. The tobacco plant, however, is an ideal target for GM, since its genetics are very well understood and it produces a lot of leaves. The value of the drugs that could be produced by GM tobacco is so high, many fanners could switch from growing tobacco for cigarettes to growing it for medicine. Since medical cost is rising, consumers would also be happy to use drugs produced in bulk by GM tobacco.

According to the passage, why are researchers developing GM trees?

A. to improve or make paper less expensive 

B. to produce more fruit 

C. to find a way to make paper without pulp 

D. to replace trees cut down for paper

As heart disease continues to be the number-one killer in the United States, researchers have become increasingly interested in identifying the potential risk factors that trigger heart attacks. High-fat diets and "life in the fast lane" have long been known to contribute to the high incidence of heart failure. But according to new studies, the list of risk factors may be significantly longer and quite surprising.

Heart failure, for example, appears to have seasonal and temporal patterns. A higher percentage of heart attacks occur in cold weather, and more people experience heart failure on Monday than on any other day of the week. In addition, people are more susceptible to heart attacks in the first few hours after waking. Cardiologists first observed this morning phenomenon in the mid-1980, and have since discovered a number of possible causes. An early-morning rise in blood pressure, heart rate, and concentration of heart stimulatin hormones, plus a reduction of blood flow to the heart, may all contribute to the higher incidence of heart attacks between the hours of 8:00 A.M. and 10:00 A.M.

In other studies, both birthdays and bachelorhood have been implicated as risk factors. Statistics reveal that heart attack rates increase significantly for both females and males in the few days immediately preceding and following their birthdays. And unmarried men are more at risk for heart attacks than their married counterparts. Though stress is thought to be linked in some way to all of the aforementioned risk factors, intense research continues in the hope of further comprehending why and how heart failure is triggered .

Which of the following is NOT cited as a possible risk factor?

A. Having a birthday

B. Getting married

C. Eating fatty foods

D. Being under stress
