A Harvard researcher is pointing toward a new reason to worry about the effects of climate change — national security. A new report co-authored by Michael McElroy, the Gilbert Butler Professor of Environmental Studies, and D. James Baker, a former administrator of the National Oceanic and Atmospheric Administration, connects global climate change, extreme weather, and national security. During the next decade, the report concludes, climate change could have wide-reaching effects on everything from food, water, and energy supplies to critical infrastructure and economic ...

AMES, Iowa – An international team of astronomers has used nearly three years of high precision data from NASA's Kepler spacecraft to make the first observations of a planet outside our solar system that's smaller than Mercury, the smallest planet orbiting our sun. The planet is about the size of the Earth's moon. It is one of three planets orbiting a star designated Kepler-37 in the Cygnus-Lyra region of the Milky Way. The findings are published were published online on Feb. 20 by the journal Nature. The lead authors are Thomas Barclay of the NASA Ames Research Center ...

Philadelphia - According to a new study by researchers at the Perelman School of Medicine at the University of Pennsylvania, patients with Barrett's esophagus and early or pre-cancerous cells have been shown to significantly benefit from minimally invasive therapy delivered through an endoscope – a medical instrument used to look inside an organ or cavity in the body. Until recently, patients with these conditions were treated by surgery to remove the whole esophagus. Study results show that endoscope-based therapies have a high success rate; all of the damaged cells were ...

SEATTLE – An international research team co-led by cancer prevention researcher Ulrike "Riki" Peters, Ph.D., M.P.H., and biostatistician Hsu Li, Ph.D., at Fred Hutchinson Cancer Research Center has identified variations in four genes that are linked to an increased risk of colorectal cancer. Peters and colleagues from 40 institutes throughout the world published their findings online ahead of the April print issue of Gastroenterology. Peters and colleagues for the past four years have been studying the genes linked to colorectal cancer through the Genetics and Epidemiology ...

CHICAGO --- U.S. veterans diagnosed with gastroesophageal reflux disease (GERD) are frequently prescribed doses of proton pump inhibitors (PPIs), such as omeprazole (commonly known by brand names such as Prilosec), that are much higher than recommended --- and they are kept on the drug far too long, according to a new Northwestern Medicine® study. PPIs are among the most widely used drugs in the nation, resulting in more than $11 billion in annual direct health care costs in the U.S. PPI overuse has been documented in previous studies, but this is the first study to examine ...

As magnetic fields on the sun rearrange and realign, dark spots known as sunspots can appear on its surface. Over the course of Feb. 19-20, 2013, scientists watched a giant sunspot form in under 48 hours. It has grown to over six Earth diameters across but its full extent is hard to judge since the spot lies on a sphere not a flat disk. The spot quickly evolved into what's called a delta region, in which the lighter areas around the sunspot, the penumbra, exhibit magnetic fields that point in the opposite direction of those fields in the center, dark area. This is a fairly ...

INDIANAPOLIS -- A study combining genetic data with brain imaging, designed to identify genes associated with the amyloid plaque deposits found in Alzheimer's disease patients, has not only identified the APOE gene -- long associated with development of Alzheimer's -- but has uncovered an association with a second gene, called BCHE. A national research team, led by scientists at the Indiana University School of Medicine, reported the results of the study in an article in Molecular Psychiatry posted online Tuesday. The study is believed to be the first genome-wide association ...

Researchers from The University of Texas at Arlington are pioneering a new method for using carbon dioxide, or CO2, to make liquid methanol fuel by using copper oxide nanowires and sunlight. The process is safer, simpler and less expensive than previous methods to convert the greenhouse gas associated with climate change to a useful product, said Krishnan Rajeshwar, interim associate vice president for research at UT Arlington and one of the authors of a paper recently published in the journal Chemical Communications. Researchers began by coating the walls of copper oxide, ...

Gravity remains the dominant force on large astronomical scales, but when it comes to stars in young star clusters the dynamics in these crowded environments cannot be simply explained by the pull of gravity. After analyzing Hubble Space Telescope images of star cluster NGC 1818 in the Large Magellanic Cloud, a satellite galaxy of the Milky Way, researchers at the Kavli Institute for Astronomy and Astrophysics (KIAA) at Peking University in Beijing found more binary star systems toward the periphery of cluster than in the center – the opposite of what they expected. The ...

(SACRAMENTO, Calif.) — Gun violence in the United States can be substantially reduced if Congress expands requirements for background checks on retail gun sales to cover firearm transfers between private parties, a new report by the director of the UC Davis Violence Prevention Research Program concludes. The report "Background Checks for Firearm Transfers" by Garen Wintemute, who also serves as a professor of emergency medicine, notes that 40 percent of U.S. gun transactions occur between unlicensed private parties, such as people buying and selling at gun shows.

COLUMBIA, Mo. – After retirement, pensions provide consistent income to aging individuals. Although the details of pension eligibility and implementation vary by country, receiving pensions can represent a new life stage for individuals. Now, a University of Missouri researcher has studied how older men and women view their health before and after receiving fixed incomes. South African men and women in the study viewed their health more positively when they began receiving their pensions, but the heightened sense of well-being faded over time. "We looked at individuals' ...

Fetal alcohol syndrome is the leading preventable cause of developmental disorders in developed countries. And fetal alcohol spectrum disorder (FASD), a range of alcohol-related birth defects that includes fetal alcohol syndrome, is thought to affect as many as 1 in 100 children born in the United States.
