A study by Dartmouth and Australian researchers provides the first empirical evidence using data from a variety of countries that foreign aid can greatly improve foreign public opinion of donor countries. The findings are based on a U.S. foreign aid program targeting HIV and AIDS -- the President's Emergency Plan for AIDS Relief (PEPFAR) -- that has substantially improved public perception of the United States in the more than 80 developing countries receiving the aid. But the findings have broader policy implications for an emerging international order in which major ...

INDIANAPOLIS -- Researchers at the Indiana University School of Medicine have discovered a highly accurate, noninvasive test to identify benign pancreatic cysts, which could spare patients years of nerve-racking trips to the doctor or potentially dangerous surgery.

The test, which analyzes fluid from pancreatic cysts, can identify a common type of benign cyst that ...

SAN ANTONIO (February 11, 2014) – There are potentially effective treatments for acute myeloid leukemia (AML), but they only work in 20 to 40 percent of cases. In a paper published today in Leukemia, a Nature journal, a UT Health Science Center researcher has pinpointed a protein that could play a key, previously unknown role in the development of pediatric AML — promising new information in the quest to treat and cure childhood leukemias. AML starts at the point when cells mature into different kinds of blood cells. In AML, the cancerous cells grow and proliferate in ...

Juggling may seem like mere entertainment, but a study led by Johns Hopkins engineers used this circus skill to gather critical clues about how vision and the sense of touch help control the way humans and animals move their limbs in a repetitive way, such as in running. The findings eventually may aid in the treatment of people with neurological diseases and could lead to prosthetic limbs and robots that move more efficiently. The study was published online recently by the Journal of Neurophysiology and will be the cover article in the journal's March 2014 print edition. In ...

Children with cancer are being denied new, potentially life-saving drugs, because EU rules are allowing companies to trial some drugs only in adults, leading cancer experts warn today. Changes to how EU rules are implemented could allow children access to a goldmine of potential cancer drugs which have currently only been tested in adults – by making it more difficult for pharma companies to avoid testing them in under-18s too. Under the current system, pharma companies often gain exemptions from carrying out expensive testing of cancer drugs in patients under the age ...

As climate change unfolds over the next century, plants and animals will need to adapt or shift locations to follow their ideal climate. A new study provides an innovative global map of where species are likely to succeed or fail in keeping up with a changing climate. The findings appear in the science journal Nature. As part of a UC Santa Barbara National Center for Ecological Analysis and Synthesis (NCEAS) working group, 18 international researchers analyzed 50 years of sea surface and land temperature data (1960-2009). They also projected temperature changes under ...

ROSEMONT, Ill.─Pediatric obesity is currently an epidemic, with the prevalence having quadruped over the last 25 years. Children diagnosed with obesity can be at risk for various long-term health issues and may be putting their musculoskeletal system at risk. According to new research in the February issue of the Journal of Bone and Joint Surgery (JBJS), obese children who sustain a supracondylar humeral (above the elbow) fracture can be expected to have more complex fractures and experience more postoperative complications than children of a normal weight. "These ...

The largest mass extinction in the history of animal life occurred some 252 million years ago, wiping out more than 96 percent of marine species and 70 percent of life on land — including the largest insects known to have inhabited the Earth. Multiple theories have aimed to explain the cause of what's now known as the end-Permian extinction, including an asteroid impact, massive volcanic eruptions, or a cataclysmic cascade of environmental events. But pinpointing the cause of the extinction requires better measurements of how long the extinction period lasted. Now researchers ...

The pollutants measured in the sediments of Guánica Bay, Puerto Rico, in a new NOAA study were among the highest concentrations of PCBs, chlordane, chromium and nickel ever measured in the history of NOAA's National Status & Trends, a nationwide contaminant monitoring program that began in 1986. Researchers from the National Ocean Service's National Centers for Coastal Ocean Science (NCCOS) studied the reef's ecology to help establish baseline conditions that coastal managers can use to measure changes resulting from new efforts to manage pollution. Among the items studied ...

Some towering thunderstorms were spotted in Tropical Cyclone Fobane as NASA's TRMM satellite passed over the Southern Indian Ocean on February 10. Fobane was formerly Tropical Cyclone 14S and when it strengthened into a tropical storm it was renamed. NASA and the Japan Aerospace Exploration Agency manages the Tropical Rainfall Measuring Mission satellite known as TRMM. TRMM has the capability to measure rainfall rates from space and data that can be used to determine the heights of thunderstorms that make up a storm. When TRMM passed over Tropical Cyclone Fobane on February ...

The spread of obesity and type-2 diabetes could become epidemic in low-income countries, as more individuals are able to own higher priced items such as TVs, computers and cars. The findings of an international study, led by Simon Fraser University health sciences professor Scott Lear, are published today in the Canadian Medical Association Journal. Lear headed an international research team that analyzed data on more than 150,000 adults from 17 countries, ranging from high and middle income to low-income nations. Researchers, who questioned participants about ownership ...

Studying a cycle of protein interactions needed to make fat, Johns Hopkins researchers say they have discovered a biological switch that regulates a protein that causes fatty liver disease in mice. Their findings, they report, may help develop drugs to decrease excessive fat production and its associated conditions in people, including fatty liver disease and diabetes. A summary of the research appeared online on Jan. 29 in the Journal of Biological Chemistry. "We've learned how the body finely tunes levels of a protein called SCAP that is required to turn on fat production ...

The brain contains a defense system that prevents at least two unrelated viruses—and possibly many more—from invading the brain at large. The research is published online ahead of print in the Journal of Virology. "Our work points to the remarkable ability of the immune system, even within the brain, to protect us against opportunistic viruses," says Anthony van den Pol of Yale University, an author on the study. The research explains a long-standing mystery. The olfactory mucosa in the nose can serve as a conduit for a number of viruses to enter the brain including ...

ROCHESTER, Minn. — Mayo Clinic researchers have shed light on a new mechanism by which prostate cancer develops in men. Central to development of nearly all prostate cancer cases are malfunctions in the androgen receptor — the cellular component that binds to male hormones. The research team has shown that SPOP, a protein that is most frequently mutated in human prostate cancers, is a key regulator of androgen receptor activity that prevents uncontrolled growth of cells in the prostate and thus helps prevent cancer. The findings appear in the journal Cell Reports. "By ...

Martian experts have known since 2011 that mysterious, possibly water-related streaks appear and disappear on the planet's surface. Georgia Institute of Technology Ph.D. candidate Lujendra Ojha discovered them while an undergraduate at the University of Arizona. These features were given the descriptive name of recurring slope lineae (RSL) because of their shape, annual reappearance and occurrence generally on steep slopes such as crater walls. Ojha has been taking a closer look at this phenomenon, searching for minerals that RSL might leave in their wake, to try to understand ...

COLUMBUS, Ohio—High hopes may help move a rubber tree plant (as the old song goes), but the real secret to the ant's legendary strength may lie in its tiny neck joint. In the Journal of Biomechanics, researchers report that the neck joint of a common American field ant can withstand pressures up to 5,000 times the ant's weight. "Ants are impressive mechanical systems—astounding, really," said Carlos Castro, assistant professor of mechanical and aerospace engineering at The Ohio State University. "Before we started, we made a somewhat conservative estimate that they ...
