The use of different materials with varied textures improves the recognition of tactile images by young blind people. This result emphasizes that early, regular use of tactile material by blind children is necessary to improve recognition through touch.
Spit conjures a variety of sayings and images for most people, but for some researchers, spit is also serious business. In a recent study, scientists tracked the release of nerve growth factor in saliva (sNGF), finding for the first time that this protein typically linked to the survival, development or function of neurons may be an important player in understanding the body’s response to stress.
As more and more people recognize the importance of the wild relatives of crop plants to agriculture and food security, interest in cataloging and conserving these plants is building around the world. Agricultural researchers are working to identify and protect the wild relatives of domesticated crop plants both in the United States and abroad.
Chronic use of prescription painkillers, also known as opioids, among obese patients prior to bariatric surgery continues after surgery, according to a new study.
According to a recent study, waiting actually does make people more patient, which can provide a payoff for consumers by helping them make better decisions.
Association between high BMI and cardiovascular disease is stronger among east Asians than south Asians
A study has found that the association between body fat and mortality due to cardiovascular disease differs between south and east Asians, a finding that has important implications for global health recommendations.
Researchers have gained new insight into how localized hearing works in the brain.
A study published suggests an association between smoking during pregnancy and increased risk for developing bipolar disorder in adult children. Researchers evaluated offspring from a large cohort of pregnant women and found that maternal smoking during pregnancy was associated with a twofold increased risk of bipolar disorder in their offspring.
Scientists have recorded a drastically reduced measurement of the Casimir effect, a fundamental quantum phenomenon experienced between two neutral bodies that exist in a vacuum.
A new computational tool developed by US and Israeli scientists will help scientists exploit the massive databases of gene expression experimental results that have been created over the past decade. Researchers say it could uncover new links between diseases and treatments and provide new insights into biological processes.
Women who gain excessive weight in pregnancy are more likely to have overweight and obese children.
Physical activity is potentially as effective as many drug interventions for patients with existing coronary heart disease and stroke, suggests a review of evidence.
An immediate and chronic concern for many of us is how the housing market influences the whole economy: surprisingly ants also have issues over the value of new homes, researchers from the University of Bristol have found.
When researchers collect human tissue in a so-called bio bank, the purpose is usually to learn about various diseases and improve curing of them. But a group of researchers are in the process of creating a bio bank, which will generate knowledge about the legal and ethical aspects of bio banking as well as contributing to medical research.
Drilling cores from Switzerland have revealed the oldest known fossils of the direct ancestors of flowering plants. These beautifully preserved 240-million-year-old pollen grains are evidence that flowering plants evolved 100 million years earlier than previously thought, according to a new study. Flowering plants evolved from extinct plants related to conifers, ginkgos, cycads, and seed ferns. The oldest known fossils from flowering plants are pollen grains. These are small, robust and numerous and therefore fossilize more easily than leaves and flowers. An uninterrupted sequence of fossilized pollen from flowers begins in the Early Cretaceous, approximately 140 million years ago, and it is generally assumed that flowering plants first evolved around that time. But the present study documents flowering plant-like pollen that is 100 million years older, implying that flowering plants may have originated in the Early Triassic (between 252 to 247 million years ago) or even earlier.
Lessons learned from California's health insurance marketplace, similar to the health insurance exchanges under the Affordable Care Act.
Kibale National Park is an almost 500-square-mile forest in western Uganda. Here scientists frequently study how infectious diseases spread and evolve in the wild. One scientist returned with a "stow-away" -- a new species of tick.
Researchers created and validated a risk score called renal risk index based upon the liver transplant recipient's characteristics at the time of transplant to predict the post- transplant end-stage renal disease.
Making health care insurance more affordable is one key goal of the Affordable Care Act. A new study finds that out-of-pocket medical expenses will decline for most consumers who become newly insured or change their source of health insurance under the program.
A person wielding a gun focuses more intently on the face of an opponent with a gun, presumably to try to determine that person's likelihood of pulling the trigger, according to a new study on gun-in-hand research.
