Scientists have conducted the world's most comprehensive analysis of coral genes, focusing on how their evolution has allowed corals to interact with and adapt to the environment.
The results are in from the first international clinical trial evaluating the effect of intense physical exercise to improve survival of men with advanced prostate cancer.
A multidisciplinary team of researchers gives birth to a unique method that enables instant, specific labeling of individual cells, Cell Labelling via Photobleaching (CLaP). This method will become a precious ally in a wide range of scientific research, with particular applications for genomics.
A family of compounds known as perovskites, which can be made into thin films with many promising electronic and optical properties, has been a hot research topic in recent years. But although these materials could potentially be highly useful in applications such as solar cells, some limitations still hamper their efficiency and consistency. Now, a team of researchers say they have made significant inroads toward understanding a process for improving perovskites' performance, by modifying the material using intense light.
One in four patients develop heart failure within four years of a first heart attack, according to a new study in nearly 25,000 patients. Risk factors included older age, greater socioeconomic deprivation, and comorbidities such as diabetes.
The visible impacts of depression and stress can be found in alterations in genetic activity, according to newly published research.
The discovery of early changes in the cells of the Fallopian tubes of women carrying the BRCA genetic mutation could open the way for new preventative strategies for ovarian cancer, reducing the need for invasive surgery, according to new research.
Whole-exome sequencing of both colorectal adenomas (precancers often called polyps) and intestinal mucosa at risk for developing into adenomas from patients with familial adenomatous polyposis (FAP) has generated a comprehensive picture of the genomic alterations that characterize the evolution of normal mucosa to precancer.
Researchers report an association between smoking during pregnancy and increased risk for schizophrenia in children. The paper evaluated nearly 1,000 cases of schizophrenia and matched controls among offspring born in Finland from 1983-1998. Results showed that a higher maternal nicotine level in the mother's blood was associated with an increased risk of schizophrenia among their offspring. The study provides the most definitive evidence to date that smoking during pregnancy is associated with schizophrenia.
The results of a new study on physical activity have researchers asking what in the world will it take to get people moving. It looks like even wearing a fitness monitor isn't enough to do the trick.
A five-week obesity prevention program for seventh grade students in Southern California helped obese students lose weight over a long-term period. The average reduction in body mass index (BMI) measured for obese students of average height two years later when they entered high school translated into about nine pounds lower bodyweight.
Teenage pregnancies hit record low, reflecting efforts of England's strategy to reduce under-18 conceptions
Rates of teenage pregnancy in England have halved since the implementation of the Government's Teenage Pregnancy Strategy (TPS) in 1999, and the greatest effect is seen in areas of high deprivation and areas that received the most TPS funding, according to research.
Cardiomyopathy, or a deterioration of the ability of the heart muscle to contract, generally leads to progressive heart failure. It is frequently inherited, and, because approximately 40 percent of children born with it are likely to die within five years of diagnosis, being able to identify its genetic basis is particularly important. Now, an international team of researchers has identified a new disease gene which is implicated in the development of severe pediatric cardiomyopathies.
Fluctuations in blood pressure readings over a five-year period resulted in faster declines in brain and cognitive function among older adults. Controlling this blood pressure instability may be a strategy to preserve cognitive function among older adults, researchers report.
Loss of Y chromosome is a risk factor for Alzheimer's disease: Why do men have shorter lives than women?
The loss of the Y chromosome in batches of cells over time continues to develop as one biological explanation for why men, on average, live shorter lives than women. Researchers found that men with blood samples showing loss of chromosome Y developed Alzheimer's as often as people born with genes that put them at the most risk for the disease.
Researchers have made the first microscopic movies of liquids getting vaporized by the world’s brightest X-ray laser. The new data could lead to better and novel experiments at X-ray lasers, whose extremely bright, fast flashes of light take atomic-level snapshots of some of nature’s speediest processes.
Scientists have detected and confirmed the faintest early-universe galaxy ever, using the W. M. Keck Observatory on the summit on Mauna Kea in Hawaii. The team detected the galaxy as it was 13 billion years ago.
Exposure to e-cigarette marketing messages is significantly associated with e-cigarette use among middle school and high school students, according to researchers.
Stores should take shoppers' emotions into account when setting prices, and a new article outlines why. Indeed, some retailers could have profits 7 to 10 percent higher if they pursued different pricing strategies, the study finds.
Chloride plays a key role in the formation of the basement membrane, a suprastructure on the outside of cells that undergirds and guides the function of most of the tissues of the body. In particular, chloride signals the assembly of collagen IV 'smart scaffolds,' a critical step in basement membrane formation, researchers report.
