DALLAS, Sept. 14, 2015 -- Black patients and patients with low socioeconomic status have shorter life expectancies after a heart attack. However, the largest racial differences in life expectancy after a heart attack occur in patients with high socioeconomic status, according to research in the American Heart Association journal Circulation. "Race and socioeconomic status are intimately related, with black individuals bearing a disproportionate burden of the poverty and health inequalities in the U.S.," said Emily Bucholz, M.D., MPH, Ph.D., lead author of the study and ...

The processes of globalization should have contributed to reduced inequality in the world. In reality, however, the situation looks differently, with income inequality in the populations of developing economies growing. To correct this, the level of education of low-skilled workers must be increased, said Eric Maskin, Chief Research Fellow at the HSE International Laboratory of Decision Choice and Analysis and Nobel Laureate in Economics for 2007. In the last 20 years, the world has experienced unprecedented growth in global markets. Trading borders between countries ...

TV screens that roll up. Roofing tiles that double as solar panels. Sun-powered cell phone chargers woven into the fabric of backpacks. A new generation of organic semiconductors may allow these kinds of flexible electronics to be manufactured at low cost, says University of Vermont physicist and materials scientist Madalina Furis. But the basic science of how to get electrons to move quickly and easily in these organic materials remains murky. To help, Furis and a team of UVM materials scientists have invented a new way to create what they are calling "an electron ...

Free - or very inexpensive - online courses have become quite a trend in education. Massive Open Online Course (MOOC) providers currently offer thousands of courses and have enticed millions of students to enroll. The emphasis in MOOCs is often on lecture videos that students watch and learn from. However, a study published in the Proceedings of the Second (2015) ACM Conference on Learning @ Scale shows that this central approach of MOOCs - having students watch to learn - is ineffective. Instead, the emphasis on interactive activities as advocated by Carnegie Mellon ...

KINGSTON - New research out of Queen's University has found evidence of emotional load sharing between partners in a close relationship. The study, co-authored by PhD candidate Jessica Lougheed, found that a strong relationship with a loved one can help ease stress when placed in difficult situations. "We wanted to test a new evolutionary theory in psychology called Social Baseline Theory which suggests that humans adapted to be close to other humans," says Ms. Lougheed. "The idea is that individuals function at a relative deficit when they are farther away from people ...

This news release is available in Spanish. The plants on the highest mountain in Ecuador have migrated more than 500 meters to higher altitudes during the last two centuries. This is determined in a new study, in which Aarhus University researchers compared Humboldt's data from 1802 with current conditions. Although most of the world's species diversity is found in tropical areas, there are very few studies that have examined whether tropical mountain species are affected by climate change to the same extent as temperate species. A new study has now determined ...

A recently identified molecule produced by skeletal muscle in response to exercise, has been shown to increase bone mass, according to a collaborative study between researchers at the Mount Sinai Bone Program, Icahn School of Medicine at Mount Sinai, the Department of Experimental and Clinical Medicine at University of Ancona in Italy, and the Department of Basic Medical Science, Neuroscience and Sense Organs at the University of Bari in Italy, and published online today in the Proceedings of the National Academy of Sciences (PNAS). Although exercise is a well known ...

People with congenital stationary night blindness, or CSNB, have normal vision during the day but find it difficult or impossible to distinguish objects in low light. This rare condition is present from birth and can seriously impact quality of life, especially in locations and conditions where artificial illumination is not available. Working in collaboration with Japanese scientists, researchers at the University of Pennsylvania have for the first time found a form of CSNB in dogs. Their discovery and subsequent hunt for the genetic mutation responsible may one day ...

A new study from the Gladstone Institutes shows for the first time that impairments in mitochondria--the brain's cellular power plants--can deplete cellular energy levels and cause neuronal dysfunction in a model of neurodegenerative disease. A link between mitochondria, energy failure, and neurodegeneration has long been hypothesized. However, no previous studies were able to comprehensively investigate the connection because sufficiently sensitive tests, or assays, were not available to measure ATP (the energy unit of the cell that is generated by mitochondria) in individual ...

WASHINGTON (Sept. 14, 2015) -- According to initial results of a multi-site landmark study, led by Dominic Raj, M.D., at the George Washington University (GW) site, cardiovascular disease morbidity is significantly reduced through intensive management of high blood pressure. By targeting a blood pressure of 120 millimeters of mercury (mm Hg), lower than current guidelines, researchers found that adults 50 years and older also significantly reduced their rates of cardiovascular disease and cardiovascular events, such as heart attack and heart failure, as well as stroke, ...

Humans are extremely choosy when it comes to mating, only settling down and having kids after a long screening process involving nervous flirtations, set-ups by friends, online matchmaking sites, awkward dates, humiliating rejections, hasty retreats and the occasional lucky strike. In the end, we "fall in love" and "live happily ever after." But evolution is an unforgiving force - isn't this choosiness rather a costly waste of time and energy when we should just be "going forth and multiplying?" What, if anything, is the evolutionary point of it all? A new study may have ...

MRSA is bad news. If you've never heard of it, here's what you need to know: It's pronounced MER-suh, it's a nasty bacterial infection and it can cause serious disease and death. Senior molecular biology major Jacob Hatch knows MRSA as the infection that took his dad's leg. Hatch was thousands of miles away on an LDS (Mormon) mission when Methicillin-Resistant Staphylococcus aureus decalcified the bones in his dad's foot and lower leg, leading to an emergency amputation just below the knee. "It was really hard to hear the news--you never expect to hear someone in ...

Irvine, Calif., Sept. 14, 2015 -- University of California, Irvine researchers with the School of Medicine have identified the mechanism by which valproic acid controls epileptic seizures, and by doing so, also revealed an underlying factor of seizures. Valproic acid is widely used to treat various types of seizure disorders, but to this point, the cellular mechanism affected by its anticonvulsant properties were not well understood. Dr. Naoto Hoshi, an associate professor of pharmacology and physiology & biophysics, and colleagues discovered that valproic acid preserved ...

Athens, Ga. - Microbiology researchers at the University of Georgia studying a soil bacterium have identified a potential mechanism for neurodegenerative diseases. A role for the protein HSD10 had been suspected in patients with Alzheimer's disease and Parkinson's disease, but no direct connection had previously been established. This new breakthrough suggests that HSD10 reduces oxidative stress, promotes cell repair and prevents cellular death. The authors first discovered that an enzyme related to HSD10, CsgA, produces energy during sporulation in the bacterium ...

A new review has produced the most conclusive evidence to date that people consume more food or non-alcoholic drinks when offered larger sized portions or when they use larger items of tableware. The research, carried out by the University of Cambridge and published in the Cochrane Database of Systematic Reviews, suggests that eliminating larger-sized portions from the diet completely could reduce energy intake by up to 16% among UK adults or 29% among US adults. Overeating increases the risks of heart disease, diabetes, and many cancers, which are among the leading causes ...

Single grandparents raising grandchildren are more vulnerable to poor physical and mental health than are single parents, according to a study recently published in Current Gerontology and Geriatrics Research. These caregivers may be at greater risk for diminished physical capacity and heightened prevalence of depression, researchers found. Researchers at Georgia State University and the University of Toronto found that solo grandparents caring for grandchildren fare worse than single parents across four critical health areas: physical health, mental health, functional ...

SAN FRANCISCO--After analyzing the seismic waves produced by small underground chemical explosions at a test site in Vermont, scientists say that some features of seismic waves could be affected by the amount of gas produced in the explosion. This unexpected finding may have implications for how scientists use these types of chemical explosions to indirectly study the seismic signal of nuclear detonations. Researchers use chemical blasts to learn more about the specific seismic signatures produced by explosions--which differ from those produced by earthquakes--to help ...

A new guideline that aims to prevent fractures in residents of long-term care facilities is targeted at frail seniors and their families as well as health care workers. The guideline, published in CMAJ (Canadian Medical Association Journal), was developed with input from residents of long-term care facilities and their families, as well as researchers and health care professionals. Seniors living in long-term care homes have a two- to four-fold risk of sustaining a fracture such as a hip or spinal fracture, compared with adults of similar age living in the community. ...

Scientists have identified a gene - FOXC1 - that, if switched on, causes more aggressive cancer in a fifth of acute myeloid leukaemia (AML) patients, according to a Cancer Research UK study* published in the journal Cancer Cell, today. The FOXC1 gene is normally switched on during embryonic development and is needed to turn cells into specialised tissues, like the eyes, kidney, brain and bone. But this new research found that in certain patients with AML - a type of blood cancer that affects white blood cells and the bone marrow - this gene was wrongly switched on inside ...

(BOSTON) - Stem cell therapies are often limited by low survival of transplanted stem cells and the lack of precise control over their differentiation into the terminal cell types needed to repair or replace injured tissues. Now, a team led by Wyss Institute Core Faculty member David Mooney, Ph.D., has developed a new strategy - embedding stem cells into porous, transplantable hydrogels - that has experimentally improved bone repair by boosting the survival rate of transplanted stem cells and influencing their cell differentiation. Mooney - who is also the Robert P. Pinkas ...

(Boston)--A panel of experts and researchers have developed a new classification system for gout, the most common form of inflammatory arthritis. This new system standardizes the classification of this condition using a variety of evidence-based criteria. Led by a researchers at Boston University School of Medicine (BUSM) and institutions from around the world, the study is a joint publication appearing in two journals simultaneously, Annals of Rheumatologic Disease and Arthritis & Rheumatology. Gout is characterized by the deposition of a specific type of crystal in ...

GAINESVILLE, Fla. -- Larger and private colleges and universities seem to attract hookah cafes and lounges, but smoke-free policies decrease these odds, according to findings published in the American Journal of Preventive Medicine this month. That may bode well for the long-term health of college-age students. Waterpipe smoking, more commonly known as hookah, boasts enticing flavors and a healthier reputation, increasing its popularity among college students. It is estimated that more than 10 percent of U.S. college students are current users. However, recent evidence ...

MADISON, Wis. -- Hydrogen could be the ideal fuel: Whether used to make electricity in a fuel cell or burned to make heat, the only byproduct is water; there is no climate-altering carbon dioxide. Like gasoline, hydrogen could also be used to store energy. Hydrogen is usually produced by separating water with electrical power. And although the water supply is essentially limitless, a major roadblock to a future "hydrogen economy" is the need for platinum or other expensive noble metals in the water-splitting devices. Noble metals resist oxidation and include many ...

Montreal, September 14, 2015 - Using extensive genetic data compiled by the UK10K project, an international team of researchers led by Dr. Brent Richards of the Lady Davis Institute at the Jewish General Hospital has identified a genetic variant near the gene EN1 as having the strongest effect on bone mineral density (BMD) and fracture identified to date. The findings are published in the forthcoming issue of the prestigious journal Nature. "EN1 has never before been linked to osteoporosis in humans, so this opens up a brand new pathway to pursue in developing drugs to ...
