New Rochelle, NY, August 5, 2019--A new study supports the use of virtual patients and in silico clinical studies to evaluate the effectiveness of blue light to reduce the symptoms of psoriasis. Researchers also demonstrated that this in silico approach can be used to improve the treatment response of patients with psoriasis to blue light by modifying the settings of the therapeutic protocol, as reported in the study published in Systems Medicine, an open access journal from Mary Ann Liebert, Inc., publishers.
Semiconducting polymers, very large chain-like molecules made from repeating sub-units, are increasingly drawing the attention of researchers because of their potential applications in organic electronic devices. Like most semiconducting materials, semiconducting polymers can be classified as p-type or n-type according to their conducting properties. Although p-type semiconducting polymers have seen dramatic improvements thanks to recent advances, the same cannot be said about their n-type counterparts, whose electron-conducting characteristics (or 'electron mobility') are still poor.
Five years ago, Stanford postdoctoral scholar Momchil Minkov encountered a puzzle that he was impatient to solve. At the heart of his field of nonlinear optics are devices that change light from one color to another - a process important for many technologies within telecommunications, computing and laser-based equipment and science. But Minkov wanted a device that also traps both colors of light, a complex feat that could vastly improve the efficiency of this light-changing process - and he wanted it to be microscopic.
WINSTON-SALEM, N.C. - Aug. 6, 2019 - The internet can serve as a pathway to diagnosis and care for people who suspect they have a rare condition that has not been identified by their physicians, according to a study by researchers at Wake Forest School of Medicine, part of Wake Forest Baptist Health.
Researchers at Stanford University have found that spraying a gel on the internal tissues of animals after cardiac surgery greatly reduces adhesions, fibrous bands that form between internal organs and tissues. Adhesions can cause serious, even fatal, complications.
The gel, developed at Stanford to deliver medications, was far more effective than adhesion prevention materials currently on the market, the researchers said. It appeared to be safe in the animal study.
AMHERST, Mass. - Industry figures show the global rate of solar energy installations grew by 30 percent in one recent year, and the average cost of installing solar has fallen from $7 per watt to $2.8 per watt, making rooftop solar attractive to many more homeowners. But the progress of rooftop installations is often slowed by a shortage of trained professionals who must use expensive tools to conduct labor-intensive structure assessments one by one, say scientists at the University of Massachusetts Amherst.
Seeking social status is a central human motivation. Whether it's buying designer clothing, working the way up the job ladder, or making a conspicuous donation to charity, humans often seek and signal social status. Human cooperation and competition aren't mutually exclusive, they are two sides of the same coin.
Many animals have to move around in their environment to find resources to live and reproduce.
Scientists have studied particular examples of this for many years but there are not many unifying frameworks to understand the general organising principles of animal movement.
This is especially true for animal collectives like ant colonies, whose individual routes as they search for food can look rather like a 'random walk'.
Senior Researcher Changsoon Choi's team at DGIST Department of Smart Textile Convergence Research and Dr. Sungwoo Chun at Sungkyunkwan University (SKKU) developed artificial skin tactile sensors that can feel the similar pressure and vibration felt by human skin. The new sensors can detect more sensitive tactile than the existing ones, thus upgrading the related research further.
Researchers have developed a soft neural implant that can be wirelessly controlled using a smartphone. It is the first wireless neural device capable of indefinitely delivering multiple drugs and multiple colour lights, which neuroscientists believe can speed up efforts to uncover brain diseases such as Parkinson's, Alzheimer's, addiction, depression, and pain.A team under Professor Jae-Woong Jeong from the School of Electrical Engineering at KAIST and his collaborators have invented a device that can control neural circuits using a tiny brain implant controlled by a smartphone.
A famous experiment in 1953 showed that amino acids, the building blocks of proteins, could have formed spontaneously under the atmospheric conditions of early Earth. However, just because molecules could form doesn't mean that the process was likely. Now, researchers reporting in ACS Central Science have demonstrated that energetically feasible interactions between just two small molecules -- hydrogen cyanide and water -- could give rise to most of the important precursors of RNA and proteins.
DALLAS, August 7, 2019 -- Eating mostly plant-based foods and fewer animal-based foods may be linked to better heart health and a lower risk of dying from a heart attack, stroke or other cardiovascular disease according to new research published in the Journal of the American Heart Association, the Open Access Journal of the American Heart Association/American Stroke Association.
A study published in the Journal of the American Geriatrics Society has found that many characteristics among older adults with moderately severe dementia differ depending on whether they live at home or in residential care or nursing facilities.
Results from a new study suggest that red meat consumption may increase the risk of breast cancer, whereas poultry consumption may be protective against breast cancer risk. The findings are published in the International Journal of Cancer.
For the study, investigators analyzed information on consumption of different types of meat and meat cooking practices from 42,012 women who were followed for an average of 7.6 years.
ITHACA, N.Y. - With New York state's $20 million berry industry entering peak season, an invasive fruit fly is thriving.
But little has been known about how the pests survive before and after the growing season.
A Cornell University study, published in Ecological Entomology, investigates for the first time what spotted-wing drosophila adults and larvae eat, and where they lay their eggs, when these short-lived fruits are not in season.
