Leesburg, VA, December 16, 2019--According to an article published ahead-of-print in the February 2020 issue of the American Journal of Roentgenology (AJR), fluorodeoxyglucose PET (FDG PET) can be used to predict the histopathologic subtypes and growth patterns of early lung adenocarcinoma.
London, UK: A recent study published in the journal Cephalalgia, the official journal of the International Headache Society, reported an intriguing discovery. The study, entitled “Investigation of distinct molecular pathways in migraine induction using calcitonin gene-related peptide and sildenafil”, was conducted by Dr. Samaira Younis and colleagues from the Danish Headache Center, Rigshospitalet Glostrup, University of Copenhagen, Denmark.
A new paper to be published on 16 December provides a significant new insight into our understanding of uranium biogeochemistry and could help with the UK's nuclear legacy.
A new study led by Washington University School of Medicine in St. Louis suggests there is a link between bacteria that live in the upper airway and the severity of asthma symptoms among children with mild to moderate asthma.
The study raises the possibility that the airway's microbiome could have a causal role in the severity of asthma symptoms. The research paves the way for future studies to discover whether altering the types of bacteria that live in the upper airway could help patients with asthma.
ROCHESTER, Minn. -- Endometrial cancer is the most common gynecological malignancy in the U.S. and the fourth most common cancer among women. In addition, endometrial cancer incidence rates are on the rise in the western world, suggesting that alterations in environmental factors such as diet, lifestyle, and the vaginal microbiome may be important drivers in its cause.
An inexpensive material, made from tungsten disulfide flakes just a few atoms thick, has helped to improve the performance of organic solar cells1. The discovery by KAUST researchers could be an important step toward bringing these photovoltaic cells into wider use for generating clean electricity.
From dyes to construction materials, and from cosmetic products to electronics and medicine, nanomaterials are found in many different applications. But what are these materials? "Nanomaterials are defined purely by their size," explains Dr Kristin Schubert from the Department of Molecular Systems Biology at UFZ. "Materials between one and 100 nanometres in size are referred to as a nanomaterials." To help envisage their diminutive size: one nanometre is just one millionth of a millimetre.
Researchers have discovered gigantic clouds of gaseous carbon spanning more than a radius of 30,000 light-years around young galaxies using the Atacama Large Millimeter/submillimeter Array (ALMA). This is the first confirmation that carbon atoms produced inside of stars in the early Universe have spread beyond galaxies. No theoretical studies have predicted such huge carbon cocoons around growing galaxies, which raises questions about our current understanding of cosmic evolution.
CHAMPAIGN, Ill. -- A University of Illinois-based team of engineers has found that the model currently used to predict heat loss in a common semiconductor material does not apply in all situations. By testing the thermal properties of gallium nitride semiconductors fabricated using four popular methods, the team discovered that some techniques produce materials that perform better than others. This new understanding can help chip manufacturers find ways to better diffuse the heat that leads to device damage and decreased device lifespans.
A new statistical analysis of data from a long-term study on the teaching of mathematics and science has found that smaller class sizes are not always associated with better pupil performance and achievement.
Scientists at Tokyo Institute of Technology (Tokyo Tech) developed a new methodology that allows researchers to assess the chemical composition and structure of metallic particles with a diameter of only 0.5 to 2 nm. This breakthrough in analytical techniques will enable the development and application of minuscule materials in the fields of electronics, biomedicine, chemistry, and more.
Growing up in the wild makes plants tough. Wild plants evolve to survive the whims of nature and thrive in difficult conditions, including extreme climate conditions, poor soils, and pests and disease. Their better-known descendants - the domesticated plants that are critical to a healthy diet - are often not nearly as hardy. The genes that make crop wild relatives robust have the potential to make their cultivated cousins - our food plants - better prepared for a harsh climate future. But a series of new research papers show these critical plants are imperiled.
In the paper, a C6v-symmetric structure is thoroughly studied in which the valley Hall effect plays an important role when the Dirac cone at the corner point of the Brillouin region is opened, accompanied by a new band gap, by changing the symmetry of the structure from C6v into C3v. Further, the researchers analyze the acoustic wave propagation in two types of topological states in the range of this new band gap.
Studies have shown that perinatal exposure of rats and mice to common flame retardants found in household items permanently reprograms liver metabolism, often leading later in life to insulin resistance and non-alcoholic fatty liver disease.
The manipulation of rivers in California is jeopardizing the resilience of native Chinook salmon. It compresses their migration timing to the point that they crowd their habitats. They may miss the best window for entering the ocean and growing into adults, new research shows.
The good news is that even small steps to improve their access to habitat and restore natural flows could boost their survival.
