It is one of the first uses of genome sequencing to study the dynamics of a food-borne outbreak and provides further evidence that genomic tools can be used to investigate future outbreaks and provide greater insight into the emergence and spread of infectious diseases. http://phys.org/news247754685.html Biology Mon, 06 Feb 2012 15:00:28 EST news247754685 Global population is expected to hit 7 billion later this year, up from 6 billion in 1999. Between now and 2050, an estimated 2.3 billion more people will be added—nearly as many as inhabited the planet as recently as 1950. New estimates from the Population Division of the Department of Economic and Social Affairs of the United Nations also project that the population will reach 10.1 billion in 2100. http://phys.org/news231077458.html Other Sciences Thu, 28 Jul 2011 14:00:14 EST news231077458 The physical forces that guide how cells migrate—how they manage to get from place to place in a coordinated fashion inside the living body— are poorly understood. Scientists at the Harvard School of Public Health (HSPH) and the Institute for Bioengineering of Catalonia (IBEC) have, for the first time, devised a way to measure these forces during collective cellular migration. Their surprising conclusion is that the cells fight it out, each pushing and pulling on its neighbors in a chaotic dance, yet together moving cooperatively toward their intended direction. http://phys.org/news225287084.html Biology Sun, 22 May 2011 13:00:33 EST news225287084 Using 120 years of feathers from natural history museums in the United States, Harvard University researchers have been able to track increases in the neurotoxin methylmercury in the black-footed albatross (Phoebastria nigripes), an endangered seabird that forages extensively throughout the Pacific. http://phys.org/news222361659.html Biology Mon, 18 Apr 2011 16:07:50 EST news222361659 Although research has shown that eating fish, which is rich in beneficial omega-3 fatty acids, is associated with lower risk of cardiovascular diseases, mixed evidence from prior studies has suggested that mercury exposure from fish consumption may be linked to higher risk of cardiovascular diseases. In a new, large-scale study from Harvard School of Public Health (HSPH) and Brigham and Women's Hospital (BWH), researchers found no evidence that higher levels of mercury exposure were associated with higher risk of coronary heart disease, stroke, or total cardiovascular disease in two separate studies of U.S. adults. The study appears in the March 24, 2011, edition of the New England Journal of Medicine. http://phys.org/news220120553.html Medicine & Health Wed, 23 Mar 2011 17:36:04 EST news220120553 The World Bank and World Health Organization have voiced fears that policymakers will break their commitments to support desperately needed global health services in low- and middle-income countries because of the ongoing global economic downturn. Yet, according to a new study from the Harvard School of Public Health, there is surprisingly little historical evidence to justify reversing these commitments. http://phys.org/news217852980.html Medicine & Health Fri, 25 Feb 2011 10:44:13 EST news217852980 Elderly black patients were more likely to be readmitted to the hospital after a prior hospital stay for a heart attack, heart failure, or pneumonia, according to a new study from Harvard School of Public Health (HSPH) researchers. They found that the higher readmission rates were due to disparities related to both race and the hospitals where patients were treated. http://phys.org/news217009836.html Medicine & Health Tue, 15 Feb 2011 17:10:03 EST news217009836 Harvard School of Public Health (HSPH) researchers and colleagues from Research Institute for a Tobacco Free Society have found that a reduction in secondhand smoking in American homes was associated with fewer cases of otitis media, the scientific name for middle ear infection. The study appears on January 26, 2011, as an online first article on the website of the journal Tobacco Control. http://phys.org/news215346599.html Medicine & Health Thu, 27 Jan 2011 10:50:06 EST news215346599 The deaths of 1.8 million female infants and children in India over the past 20 years are related to domestic violence against their mothers, according to a new study led by researchers at the Harvard School of Public Health (HSPH). In their examination of over 158,000 births occurring between 1985 and 2005, the researchers found that husbands' violence against wives increased the risk of death among female children, but not male children, in both the first year and the first five years of life. http://phys.org/news213463491.html Medicine & Health Wed, 05 Jan 2011 15:40:01 EST news213463491 A new study of men with prostate cancer finds that physical activity is associated with a lower risk of overall mortality and of death due to prostate cancer. The Harvard School of Public Health and University of California, San Francisco researchers also found that men who did more vigorous activity had the lowest risk of dying from the disease. It is the first study in men with prostate cancer to evaluate physical activity after diagnosis in relation to prostate cancer-specific mortality and overall mortality. http://phys.org/news213449614.html Medicine & Health Wed, 05 Jan 2011 11:33:48 EST news213449614 Scientists at the Harvard School of Public Health (HSPH) and collaborators from other institutions have identified a natural substance in dairy fat that may substantially reduce the risk of type 2 diabetes. The compound, trans-palmitoleic acid, is a fatty acid found in milk, cheese, yogurt, and butter. It is not produced by the body and so only comes from the diet. http://phys.org/news212088644.html Medicine & Health Mon, 20 Dec 2010 18:00:03 EST news212088644 A team of Harvard School of Public Health (HSPH) scientists report finding a molecular "switch" that can "turn off" some cellular processes that are protective against aging and metabolic diseases. While more research is needed, the findings may open doors for new drug treatments to halt or slow development of metabolic diseases like type 2 diabetes or heart disease. The research findings appear in the December 1, 2010 issue of Cell Metabolism. http://phys.org/news210358891.html Biology Tue, 30 Nov 2010 17:50:03 EST news210358891 A new study from the Harvard School of Public Health (HSPH) finds that high body mass index (BMI) in developing countries remains primarily a problem of the rich. The findings suggest that the shift towards overweight and obesity among the poor that has already happened in wealthier countries has not yet happened in developing countries. http://phys.org/news209662866.html Medicine & Health Mon, 22 Nov 2010 15:41:24 EST news209662866 A new poll from researchers at the Harvard School of Public Health (HSPH) and Knowledge Networks (KN) shows that many people with heart disease, diabetes or cancer believe the economic downturn is hurting their health and will have further negative impacts in the future. Many Americans with these illnesses face financial problems paying for medical bills in this economy. Most of these people do not believe the new national health care reform law (Patient Protection and Affordable Care Act 2010) will help them. This national poll is the first in a collaborative series of polls by HSPH and KN focused on people with heart disease, diabetes, or cancer; it was conducted October 27-31, 2010. http://phys.org/news209308515.html Medicine & Health Thu, 18 Nov 2010 13:30:03 EST news209308515
