ANN ARBOR, MI - Whether it's a rare treat or a weekly routine, spending time with grandchildren brightens life for many older adults. But a new poll suggests many of them could do more to reduce the risk of their medications harming their grandchild.
More than 80% of the grandparents polled say they keep their medication in the same place as usual when their grandchildren visit their house - and 72% keep them in their purse or bag when they go to visit their grandchildren.
(Oslo, Saturday, 29 June, 2019) New results of a 65-year follow-up study of nearly 7,000 Norwegian patients with Multiple Sclerosis (MS) suggest that patients may have a greater overall risk of developing cancer than the general population, with an especially high risk of cancer in respiratory organs, urinary organs and the central nervous system.
Tokyo, Japan - Researchers from Tokyo Metropolitan University have grown atomically thin crystalline layers of transition metal dichalcogenides (TMDCs) with varying composition over space, continuously feeding in different types of TMDC to a growth chamber to tailor changes in properties. Examples include 20nm strips surrounded by different TMDCs with atomically straight interfaces, and layered structures. They also directly probed the electronic properties of these heterostructures; potential applications include electronics with unparalleled power efficiency.
RIVERSIDE, Calif. -- Thirdhand smoke can damage epithelial cells in the respiratory system by stressing cells and causing them to fight for survival, a research team led by scientists at the University of California, Riverside, has found. The finding could assist physicians treating patients exposed to thirdhand smoke.
The preservation of plant biodiversity is the task of the roughly 1,750 gene banks which are distributed around the world. So far, they store plant samples, and sometimes additional phenotypic or genetic information, of around 7,4 million accessions of plant species in total. It is expected that with the facilitated access to improved, quicker and cheaper sequencing and other omics technologies, the number of well-characterised accessions and the amount of detailed information that needs to be stored along with the biological material will be growing rapidly and continuously.
When ozone and skin oils meet, the resulting reaction may help remove ozone from an indoor environment, but it can also produce a personal cloud of pollutants that affects indoor air quality, according to a team of researchers.
In a computer model of indoor environments, the researchers show that a range of volatile and semi-volatile gases and substances are produced when ozone, a form of oxygen that can be toxic, reacts with skin oils carried by soiled clothes, a reaction that some researchers have likened to the less-than-tidy Peanuts comic strip character.
Phase transitions occur when a substance changes from a solid, liquid or gaseous state to a different state — like ice melting or vapor condensing. During these phase transitions, there is a point at which the system can display properties of both states of matter simultaneously. A similar effect occurs when normal metals transition into superconductors — characteristics fluctuate and properties expected to belong to one state carry into the other.
DURHAM, N.C. -- Biomedical engineers at Duke University have developed a low-cost, portable optical coherence tomography (OCT) scanner that promises to bring the vision-saving technology to underserved regions throughout the United States and abroad.
Thanks to a redesigned, 3D-printed spectrometer, the scanner is 15 times lighter and smaller than current commercial systems and is made from parts costing less than a tenth the retail price of commercial systems -- all without sacrificing imaging quality.
A popular imported tree that became a neighborhood favorite in the 1990s now threatens to crowd out native trees in some Eastern forests.
University of Cincinnati biologist Theresa Culley warns that for some parts of Ohio, it might be too late to stop the spread of the Callery pear. But she is urging other states to be vigilant before the invasive trees begin taking over their forests, too.
Culley presented her findings to botanists from around the world during the Society of Economic Botany conference this year hosted at UC's McMicken College of Arts and Sciences.
Solid-state batteries - a new battery design that uses all solid components - have gained attention in recent years because of their potential to hold much more energy while simultaneously avoiding the safety challenges of their liquid-based counterparts.
Interactions between electrons and phonons are regarded as the microscopic driving force behind ultrafast magnetization or demagnetization processes (spin-flips). However, it was not possible until now to observe such ultrafast processes in detail due to the absence of suitable methods.
Now, a team headed by Prof. Alexander Föhlisch has developed an original method to determine experimentally for the first time the electron-phonon driven spin-flip scattering rate in two model systems: ferromagnetic Nickel and nonmagnetic copper.
Millions of people take capsules of probiotics with the goal of improving their digestion, but what if those bacteria were also able to detect diseases in the gut and indicate when something is awry? New research from the Wyss Institute at Harvard University and Harvard Medical School (HMS) has created an effective, non-invasive way to quickly identify new bacterial biosensors that can recognize and report the presence of various disease triggers in the gut, helping set the stage for a new frontier of digestive health monitoring and treatment.
The Journal of Nuclear Medicine (JNM)--the flagship publication of the Society of Nuclear Medicine and Molecular Imaging (SNMMI)--has again been ranked among the top medical imaging journals worldwide, according to new data just released in the 2018 Journal Citation Reports© published by Clarivate Analytics.
Researchers at the universities in Stockholm and Lund, in collaboration with researchers from the University of California, have found a new toxin that selectively targets mosquitos. This can lead to innovative and environmentally friendly approaches to reduce malaria. The results are presented in an article published in Nature Communications.
