BEIJING, June 14 (Xinhuanet) -- Having a pet at home during the first year of a child may halve the risk of developing allergic to them later in life, a new study suggests.The study was published in the journal Clinical & Experimental Allergy.Researchers from Henry Ford Hospital in Detroit assessed 566 boys and girls who were followed from birth until age 18. They found that boys who had dogs and teens who had cats during their first year of life had 50 percent less risk of developing pet allergies later.Lead researcher Ganesha Wegienka said: "This research provides further evidence that experiences in the first year of life are associated with health status later in life, and that early life pet exposure does not put most children at risk of being sensitised to these animals later in life."The researchers said that exposure to animals at other times in childhood didn't appear to be as significant as the first year.However, Wegienka cautioned that this study doesn't prove a cause-and-effect relationship between having a pet and avoiding allergies, just an association between those two factors."We don't want to say that everyone should go out and get a dog or cat to prevent allergies," she said."More research is needed, though we think this is a worthwhile avenue to pursue."

BEIJING, Aug. 5 (Xinhuanet) -- A study conducted by Israeli researchers at the Albert Einstein College of Medicine in New York shows that genes, rather than good eating and lifestyle habits, determine longevity, according to media reports Friday. "This study suggests that centenarians may possess additional longevity genes that help to buffer them against the harmful effects of an unhealthy lifestyle," said senior author Nir Barzilai, director of the Institute for Aging Research at Yeshiva University's Albert Einstein College of Medicine.The study involves 477 Ashkenazi Jews between the ages of 95 and 122, of whom 75 percent are women. According to the study, Ashkenazi Jews are chosen as subjects because they are more "genetically uniform than other populations, making it easier to spot gene differences that are present."The study also found that the long-lived Ashkenazi Jews drank slightly more and exercised less than their average counterparts. But Barzilai also warned: “Although this study demonstrates that centenarians can be obese, smoke and avoid exercise, those lifestyle habits are not good choices for most of us who do not have a family history of longevity.""We should watch our weight, avoid smoking and be sure to exercise, since these activities have been shown to have great health benefits for the general population, including a longer lifespan," He added.

WASHINGTON, Aug. 18 (Xinhua) -- Black scientists were significantly less likely than their white counterparts to receive research funding from the National Institutes of Health (NIH), according to an analysis of data from 2000 to 2006.University of Kansas Professor of Economics Donna Ginther was the lead author on the study commissioned by the NIH, which will appear Friday in journal Science.The researchers found a 10 percentage point gap in research funding -- even after taking into consideration demographics, education and training, employer characteristics, NIH experience and research productivity. For example, for every 100 grants submitted to NIH, 30 grants from white applicants were funded, compared to 20 grants for black applicants.Applications for NIH funding go through peer review that considers the significance, innovation and approach of grant applications, the investigator(s) and the research environment. About half of the applications are determined to be worth scoring. Among those scored, budgets and NIH Institutes priorities determine which applications are funded. Priorities can vary by year and by Institute.The study found that applications from black researchers were less likely to be scored and on average had worse scores. After controlling for the score of the grant, there were no race or ethnicity differences in funding.Applicants self-identify race, ethnicity and gender, but that information is not available during the peer review. However, biographical facts that are included in the review materials can provide clues to the identity of the applicants.The research suggests it is possible that cumulative advantage may explain the funding differences."Small differences in access to research resources and mentoring during training or at the beginning of a career may accumulate to become large between-group differences," the paper says.Additionally, the paper suggests further research is needed to determine why black researchers are less likely to be funded.NIH Director Francis Collins and Principal Deputy Director Lawrence Tabak call the findings unacceptable and commit to immediate action by the NIH."NIH commissioned this study because we want to learn more about the challenges facing the scientific community and address them head on. The results of this study are disturbing and disheartening, and we are committed to taking action," said Collins in an accompanying commentary. "The strength of the U.S. scientific enterprise depends upon our ability to recruit and retain the brightest minds, regardless of race or ethnicity. This study shows that we still have a long way to go."NIH initiated the study in 2008 to determine if researchers of different races and ethnicities with similar research records and affiliations had similar likelihoods of being awarded a new NIH research project grant.

BEIJING, Sept. 27 (Xinhuanet) -- Scientists have been making great efforts to show how harmful coffee is to us, though no evidence yet. A latest study may be reassuring for coffee-lovers.Women who drink caffeinated coffee are less likely to be depressed than those don't. And the more they drink, the lower risk of developing depression, according to a study published Monday in the Archives of Internal Medicine. Researchers of the study tracked the health of over 50,000 women aged between 30 and 55 in 1996 for a decade and recorded their mental health and coffee intake periodically.They find that women who drank two or three cups of coffee per day were 15 percent less likely than those who drank little or decaffeinated coffee to be depressed.And for those who drank four or more cups, the risk of developing depression reduced by 20 percent.The reason why coffee could protect depression is not clear. But the scientists from the Harvard University speculated that caffeine was the key player. More research is needed to show whether caffeine can ward off depression.It might be that not-depressed people tended to be more activated and the habit of coffee drinking just fit in their lifestyle.However, the depressed ones, who might suffer from sleeplessness, chose not to drink coffee because the caffeine might exacerbate it."There's no need to start drinking coffee," said Dr. Alberto Ascherio, the senior author of the study, "The message is that coffee is safe to drink, with no adverse effects. That's really all that can be said."

GENEVA, Aug. 19 (Xinhua) -- The World Health Organization (WHO) and the UN Children's Fund (UNICEF) started an emergency vaccination campaign in all accessible areas of South and Central Somalia, WTO spokesperson Tarek Jasarevic said here on Friday.In July 2011 alone, 1,019 suspected measles cases and 31 related deaths were reported in South and Central Somalia, representing 20 percent of all reported cases for this year.The major factors for a measles outbreak in Somalia are low coverage, malnutrition, population movements, and overcrowed internally displaced (IDP) camps."WHO fears that the measles outbreak could affect a high number of people, especially among the vulnerable IDPs whose overall health is already fragile," Jasarevic said.About 2.5 million children aged between 6 and 15 in 10 regions of South and Central Somalia, including children in Mogadishu, will be targeted during this campaign.
