Turns out your mom was right: scratching an itch only makes it worse. New research reveals that scratching causes the brain to release serotonin, which intensifies the itch sensation. Scientists uncovered serotonin's role in controlling pain decades ago, but this is the first time the release of the chemical messenger from the brain has been linked to itch, they say.
The universe is an infinite sea of galaxies, which are majestic star-cities. When galaxies group together in massive clusters, some of them can be ripped apart by the gravitational tug of other galaxies. Astronomers using the HubbleShow More Summary
The Vatican debuted a cutting edge new LED lighting system in the Sistine Chapel on Wednesday. Designed and installed by the German company Osram, the new system features more than 7,000 light-emitting diodes mounted behind a cornice high up on the walls. It’s energy efficient, requiring up to 90% less electricity than the 1980s halogen [...]
Everyone can have an impact on the dynamics of a group, particularly if they join forces with others, experts say. "What interested us most, however, was how the individual can contribute to the development of stable cooperation within the group," they say of their research, which was actually able to calculate mathematically which strategies promote cooperation.
When most animals begin life, cells immediately begin accepting assignments to become a head, tail or a vital organ. However, mammals, including humans, are special. The cells of mammalian embryos get to make a different first choice -- to become the protective placenta or to commit to forming the baby.
If you think sleep problems and bladder problems are a fact of life in old age, you may be right. A new report shows that our sleep-wake cycles are genetically connected to our bladder, and disruptions to one may cause problems with the other.
Delivering life-saving drugs across the blood-brain barrier (BBB) might become a little easier thanks to a new study. In the new report, scientists describe an antibody, called 'FC5,' is one-tenth the size of a traditional antibody and able to cross the BBB.
Being overweight might be better in the long term than being underweight, at least when it comes to infants. "These findings support the hypothesis that common long-term variation in the activity of genes established in the womb may underpin links between size at birth and risk for adult disease," said one of the authors.
Scientists show, for the first time, that there is a link between perinatal exposure to Bisphenol A (BPA) at low doses and the risk to develop food intolerance in later life. "We may look back one day and see BPA exposure as one of the more important public health problems of our time," said one expert. Show More Summary
Global warming is altering the reproduction of plants and animals, notably accelerating the date when reproduction and other life processes occur. A new study has discovered that some amphibians are capable of making their offspring grow at a faster rate if they have been born later due to the climate.
The increase in the presence of plastic in our lives is an unstoppable trend due to the versatility of this material. So innovation in the packaging industry has been focusing on the development of new, more sustainable, economically...Show More Summary
Google search data really can provide a more accurate real time picture of current flu infections, researchers have found. Official reports of influenza infection rates are produced with a delay of at least one week. Yet researchersShow More Summary
A prototype running shoe has been designed with an integrated device that improves training management and prevents injuries. The device consists of a microelectronic measuring system capable of gathering biomechanical parameters that characterize the runner's technique during a race. Show More Summary
New clinical practice guidelines for treating cancer of the esophagus and gastroesophageal junction (area where the esophagus meets the stomach) have been released. The guidelines include nine evidence-based recommendations that address...Show More Summary
Reading bedtime stories, engaging in conversation and eating nightly dinners together are all positive ways in which parents interact with their children, but according to new research, none of these actions have any detectable influence on children's intelligence later in life. Show More Summary
Veterinary researchers have completed new research that suggests the bat influence virus poses a low risk to humans.
Cold-water corals of the species Lophelia pertusa are able to fuse skeletons of genetically distinct individuals. Scientists have made the first-ever discovery of branches of different colors that had flawlessly merged. The ability to fuse supports the reef stability and thus contributes to the success of corals as reef-builders of the deep sea.
Biological membranes are mainly composed of lipid bilayers. Gaining a better understanding of adsorption of solution ions onto lipid membranes helps clarify functional processes in biological cells. A new study provides a quantitative description of the equilibria between lipid membranes and surrounding solution ions. Show More Summary
Bacteria in the GI tract fulfill many vital functions and are critical for digestion. Yet, these same bacteria can induce strong inflammatory responses by the immune system if they penetrate the gut and enter the bloodstream. Prior research...Show More Summary
Pterostilbene is a phenolic compound in the same family as resveratrol and is present in small amounts in a large variety of foods and beverages like blueberries or red wine. Researchers have observed in animal models that its administration reduces the build-up of body fat, which could reduce the risk of developing other diseases like diabetes.
