A simple but effective sensor for monitoring the respiration rate of individuals has been created. Taking advantage of the hygroscopic character of ordinary paper, scientists at Harvard University have developed an electrical sensor to detect the periodic changes of humidity by breathing in and out. As they report in the journal Angewandte Chemie, the respiration data can be transmitted to and collected by nearby smartphones or tablet computers for further processing, storage, or transmittance to practical therapists. A simple face mask carrying the sensor system and worn in hospital wards may thus save lives.
We are all familiar with that strange feeling in the mouth after a sip of red wine or tea, or a bite of unripe fruit. It has been described as dry, leathery, or even furry. This astringent effect is caused by tannins or polyphenolic compounds that bind to mucins, lubricating proteins in the mucus membranes of the mouth. In the journal Angewandte Chemie, a Chinese and Korean research team has now shown the relationship between astringency and disrupted lubrication of the oral cavity.
Solar energy is on the rise. Many technical advances have made solar cells quite efficient and affordable in recent years. A big disadvantage remains in the fact that solar cells produce no power when it’s raining. This may change, however: In the journal Angewandte Chemie, Chinese researchers have now introduced a new approach for making an all-weather solar cell that is triggered by both sunlight and raindrops.
Researchers have developed a new way to prioritize investigations on the environmental impacts of the estimated 1500 active pharmaceutical ingredients currently in use.
Researchers Provide Detailed Genetic Information on Fish Commonly Used in Environmental Toxicology Studies
The fathead minnow (Pimephales promelas) has long been a premier animal model for research and regulation related to environmental toxins. Unfortunately, however, genetic information about this species is incomplete. The lack of genome sequence information for the species has limited scientists’ ability to dissect complex traits, evaluate genetic markers, identify gene regulatory sequences, and elucidate biological pathways.
John Wiley and Sons Inc., today announced a partnership with The American Institute of Chemical Engineers (AIChE) and its Society for Biological Engineering (SBE), to launch a new quarterly, peer-reviewed, open access journal, Bioengineering & Translational Medicine. To be launched in 2016 as part of the Wiley Open Access portfolio and edited by Samir Mitragotri of the University of California, Santa Barbara, the new journal will focus on ways chemical and biological engineering are driving innovations and solutions that impact clinical practice and commercial healthcare products. The journal will also highlight scientific and technical breakthroughs currently in the process of clinical and commercial translation.
The Triological Society and John Wiley and Sons, Inc. announced today the launch of a new open access publication, Laryngoscope Investigative Otolaryngology. Laryngoscope Investigative Otolaryngology is a peer-reviewed open access journal focused on the rapid dissemination of the science and practice of otolaryngology head and neck surgery. The new title is a companion journal to The Laryngoscope and will publish high-quality, original research across the spectrum of basic and clinical otolaryngology.
Mercury contamination in water and on land is of worldwide concern due to its toxic effects on ecosystems and human health. Mercury toxicity is of particular concern to reptiles because they are currently experiencing population declines. Also, reptiles are ideal indicators of mercury contamination in aquatic environments because they are long lived and occupy diverse habitats.
John Wiley & Sons, Inc., today announced a strong performance in Thomson Reuters® 2015 Journal Citation Reports (JCR) release.
Both prescription and illegal drugs that are abused have been found in Canadian surface waters. New research shows that wastewater discharges flowing downstream have the potential to contaminate sources of drinking water with these drugs at relatively low concentrations.
Researchers are developing instruments and methods for measuring the ages of rocks encountered during space missions to the Moon or other planets. Many of the techniques used to date rocks on Earth are not practical in spaceflight, but a technique called laser ablation resonance ionization mass spectrometry can avoid the need for sophisticated sample preparation.
Hyalella azteca are invertebrates that are widely used for sediment and water toxicity studies. Investigators have found that H. azteca collected from sites influenced by agricultural/urban runoff are as much as 2-times less sensitive to pyrethroid insecticides than lab-grown H. azteca. In contrast, the insecticide sensitivities of H. azteca collected from undeveloped sites beyond the influences of agricultural/urban runoff were similar to those of lab-grown populations.
Hoboken, NEW JERSEY- February 20, 2015 John Wiley & Sons, Inc. (NYSE: JWa and JWb), a global knowledge-based services provider, is honored to be the recipient of nine PROSE Awards for 2015. The PROSE Awards recognize excellence in professional and scholarly publishing by highlighting distinguished books, journals and electronic content.
Bulletin of the Korean Chemical Society expands international reach through partnership with Wiley-VCH
Wiley-VCH, part of the scientific and technical publishing business of John Wiley & Sons, Inc. (NYSE: JWa and JWb) and the Korean Chemical Society have signed an agreement to closely cooperate and jointly publish the Bulletin of the Korean Chemical Society.
The key to understanding the geologic history of the Solar System is knowing the ages of planetary rocks. Researchers have developed an instrument that is not only capable of dating rocks, but also is composed entirely of technology that can be miniaturized for spaceflight.
New analytical techniques can show how different hair care products affect the hair, with some leaving isolated deposits behind and others leaving layers of material that wet the hair surface.
John Wiley & Sons, Inc., is pleased to learn that The Royal Swedish Academy of Sciences has awarded the Nobel Prize in Chemistry for 2014 jointly to Eric Betzig, Stefan W. Hell and William E. Moerner.
John Wiley & Sons, Inc., today announced a continued increase in the proportion of its journal titles indexed in the 2014 release of Thomson Reuters Journal Citation Reports® (JCR). A total of 1,202 Wiley titles (approximately 70%) were indexed, up from 1,193 in the 2012 JCR, and including 13 titles which have been indexed for the first time.
Using a worm’s contracting and expanding motion, researchers have designed a way for gels to swim in water. The advance, which is described in a Journal of Applied Polymer Science paper, involves the use of a hand-held laser to shrink and swell polymer gels comprised mostly of water.
Students, independent researchers and small businesses can now access many of the world’s best academic papers across science, technology, medicine and other disciplines through their local libraries. This is the result of a unique collaboration between librarians and publishers, who have made their journal content available for free to UK libraries under a new initiative, Access to Research.
