Slightest touch can evoke pain in patients suffering from nerve injuries. Researchers have suppressed this type of pain in mice. They applied a chemical substance to the skin which blocked the action of an ion channel which is responsible for the perception of light touch. Activation of this channel also leads to severe pain after injuries, which the substance eliminated. The method could work in humans.
The European X-ray Free-Electron Laser (XFEL) facility, near Hamburg, Germany, was built with one objective -- to provide pulses of light short enough, bright enough, and of small enough wavelength to observe processes that would otherwise be too fast and/or too infrequent to measure in real-time.
A famine that afflicted China between 1959 and 1961 is associated with an increased hyperglycemia risk not only among people who were born then, but also among the children they had a generation later.
Engineers are the first to demonstrate that the attachment of oocysts to environmental biofilms is a calcium-mediated process -- a crucial step toward the development of an improved detection method for Cryptosporidium parvum, an infectious, sometimes deadly, parasite.
Antarctica might be one of the most inhospitable regions on the planet, but it is a mecca for astronomers. Its cold, dry air enables observations that can't be done elsewhere on Earth. The South Pole has hosted telescopes for decades. Now, researchers are eyeing a new location -- Dome A, which offers a unique opportunity to study the universe at little-explored terahertz radio frequencies.
The number of babies born with drug withdrawal symptoms from opioids grew substantially faster in rural communities than in cities, a new study suggests.
Between 2008 and 2014, more than 53 million people in 88 countries stopped smoking due to tobacco control measures, which means that more than 22 million smoking-related deaths have been averted, say authors of a new report.
Patients enrolled in a program designed to help meet socioeconomic needs that can affect their health had modest but significant improvements in several key cardiovascular risk factors, report investigators.
An analysis of the lives of nearly a thousand people shows that a small group who had poor childhood 'brain health' accounts for the lion's share of social costs when they reach adulthood. Twenty percent of participants accounted for 81 percent of criminal convictions, 77 percent of fatherless childrearing, 78 percent of prescriptions filled, 66 percent of welfare benefits, 57 percent of hospital nights, 54 percent of cigarettes smoked and 36 percent of insurance claims.
Researchers report that implementing a checklist-style set of procedures appears to cut almost in half the number of potentially unnecessary blood culture draws in critically ill children without endangering doctors' ability to diagnose and treat life-threatening blood infections.
Cigarette warning labels featuring photos of real smokers who were harmed by their habit are more effective in getting smokers to quit than the text-only labels currently in use, research indicates.
Laser scanning is a new and viable structural safety technique to detect the damaging effects of fire on concrete, new engineering research has found.
Mice that had free-access to a running wheel were able to maintain ocular dominance plasticity after suffering a stroke, compared to those that didn't, new research shows. These exciting observations have the potential to provide a simple but effective method to protect and rehabilitate patients that are prone to, or have already suffered, a stroke.
Wind farms have made a significant impact in limiting carbon emissions from other sources of power generation in Great Britain, a study shows.
Scientists have created a universal mathematical approach to queuing theory. It allows calculating the most efficient operation of the systems where the processing of incoming flow takes place. In particular, it can be used to eliminate queues in shops and banks and eliminate mobile communication congestion during the holidays.
Scientists are working to make a diamond that's predicted to be harder than a jeweler's diamond and useful for cutting through ultra-solid materials on mining sites.
Men and women are almost at an equal risk of being bullied in the workplace, but whereas bullying often causes women to go on prolonged sick leave or use antidepressants, men often choose to leave the labor market altogether for a period of time.
For the first time, targeting the other feature of Alzheimer's disease, tau, has given fruitful results. In an unprecedented study, active vaccination in humans has resulted in a favorable immune response in 29 out of the 30 patients with only minor side effects.
Neurons in zebra finch brains operate as a barcode reader to detect songs of the same species during learning, report scientists.
Researchers' discovery of new verbal working memory architecture has implications for artificial intelligence
The neural structure we use to store and process information in verbal working memory is more complex than previously understood--a discovery that has implications for the creation of artificial intelligence (AI) systems, such as speech translation tools.
