WASHINGTON, Nov. 22 (Xinhua) -- Long-term coffee consumption may be associated with a reduced risk for endometrial cancer, according to a study published online Tuesday in Cancer Epidemiology, Biomarkers & Prevention, a journal of the American Association for Cancer Research.Edward Giovannucci, professor of nutrition and epidemiology at the Harvard School of Public Health, said that coffee is emerging as a protective agent in cancers that are linked to obesity, estrogen and insulin."Coffee has already been shown to be protective against diabetes due to its effect on insulin," said Giovannucci, a senior researcher on the study. "So we hypothesized that we'd see a reduction in some cancers as well."The researchers observed cumulative coffee intake in relation to endometrial cancer in 67,470 women who enrolled in the Nurses' Health Study. During the course of 26 years of follow-up, researchers documented 672 cases of endometrial cancer.Drinking more than four cups of coffee per day was linked with a 25 percent reduced risk for endometrial cancer. Drinking between two and three cups per day was linked with a seven percent reduced risk.A similar link was seen in decaffeinated coffee, where drinking more than two cups per day was linked with a 22 percent reduced risk for endometrial cancer.Giovannucci said that he hopes this study will lead to further inquiries about the effect of coffee on cancer because in this and similar studies, coffee intake is self-selected and not randomized.

BEIJING, Oct. 12 (Xinhuanet) -- People are often recommended to eat plenty of fruits and vegetables, but only a minority people take the advice. A new research may motivate more people to do so.BBC reported a new study Tuesday that found eating lots of vegetables and fruits can weaken the effect of a gene variant called 9p21, which is reported to be one of the strongest predictors for heart disease, thereby reducing risks of heart disease.The researchers from McMaster and McGill universities studied the diets of more than 27,000 people around the world, including Europe, China, and Latin America.They found that people with the high-risk gene appeared to have a similar risk of heart disease as people with a low-risk variant of that gene after consuming a diet with a healthy amount of vegetables and fruits.But how diet has such an effect on the gene was unknown, said Dr. Sonia Anand, a lead author of the study published in PLoS Medicine journal.Anand added, "Despite having a high genetic risk for heart disease, a healthy lifestyle can actually turn off the gene."The message here is very clear, eating plenty of vegetables and fruits is definitely good to people's heart health, according to BBC.

BEIJING, Oct. 20 (Xinhuanet) -- British scientists used bacteria and DNA to build basic components for digital devices in a new research, according to media reports, suggesting biological computers come closer to reality.Digital devices are based on logic gates, fundamental building blocks in silicon circuitry, said Professor Richard Kitney, leading researcher of the research published in the journal Nature Communications, "Without them, we could not process digital information."According to Science Daily, Professor Kitney and his colleagues from the Imperial College London replicated the building blocks using bacteria and DNA, forming biological logic gates, which paved the way for building more complex biological processors in the future.The researchers hoped biological computers can be applied to monitoring human health in the future.They believed that small biological processors, inserted in human bodies, could roam inside the bodies, monitor the health, and correct any problems they found.These biological logic gates are the most advanced created by scientists. But there is still a long way to go to apply them in reality, said Professor Kitney.

SAN FRANCISCO, Nov. 4 (Xinhua) -- With its popular iPhone series, Apple seized more than half of the profits generated by the top eight mobile phone manufacturers during the third quarter, said a monthly market analysis released on Friday.Apple generated a remarkable 52 percent of handset industry operating profits for the top eight OEMs (original equipment manufacturers) in the third quarter, up five percent over the same period of 2010, said Canaccord Genuity technology analyst Michael Walkley.The number was down from 57 percent in the second quarter, due to a drop in iPhone sales as customers held out for the upcoming iPhone 4S.A proud Apple customer shows off the new iPhone 4S he purchased at an Apple store in Munich, Germany.Apple's major rival in the mobile industry is Samsung. The two companies together represented 81 percent of the handset industry' s operating profits last quarter.Other major mobile phone manufacturers are Nokia, Motorola, Sony Ericsson, HTC, Research In Motion and LG.Calling it "an epic reversal of fortunes," Walkley noted that in 2007, Nokia had 67 percent of operating profits while Apple had just 4 percent. Compared with Apple's 52 percent of industry profits in the third quarter of 2011, Nokia has been relegated to its rival's former position with just 4 percent of operating profits.The analyst said he has conducted "channel checks" that show strong demand not only for the new iPhone 4S but also for the previous models of iPhone 4 and iPhone 3GS. He told technology news website AllthingsD that Apple is believed to be able to gain further value share in the December quarter and capture over 60 percent of industry profits.In a Bloomberg report on Friday, several technology analysts said the two-year-old iPhone 3GS, whose price has been slashed to zero if it is purchased with a contract, will become one of Apple' s big weapons in the coming holiday season against smartphones running Google's Android system.
