Soils in deserts are very different from those found anywhere else. Extreme temperatures, little water and limited plant matter make an unusual environment. With little dead plant material to decompose and create a rich layer of organic matter, desert soils are unique.
Judith Turk, an assistant professor at the University of Nebraska-Lincoln, studies the top layer of desert soils, called the vesicular horizon. This surface layer of the soil is common in deserts and contains pores of different shapes, called vesicles and vughs.
New York, NY--May 6, 2019--Ammonia is a key component of fertilizer and vital in supporting plant growth and ultimately providing food for populations around the world. It is also a major pollutant that, after it is used in the food chain, enters municipal wastewater treatment plants where it is often not adequately removed. It is then released into the environment where it pollutes aquatic settings and damages ecosystems, triggering destructive algal blooms, dead zones, and fish kills.
Analysis of historical temperature data led by University of Warwick shows warm spells in winter occurring more often and for longer periods
Uses over a hundred years of data from the Central England Temperature (CET) record
Has implications for ecology, sustainability and agriculture
Warm winter spells have increased in frequency and duration two- to three times over since 1878, according to scientists led by the University of Warwick.
Bethesda, MD (May 6, 2020) -- In a new special issue of Clinical Gastroenterology and Hepatology, the clinical practice journal of the American Gastroenterological Association (AGA), leading international experts provide a comprehensive update on the treatment of inflammatory bowel diseases (IBD) for the practicing clinician.
Researchers from the Faculty of Medicine of the University of Barcelona and the CELLEX Biomedical Research Centre from IDIBAPS, in collaboration with scientists from the University of Sydney, University of London and the Research Institute Sant Joan de Déu, have identified in a study with mice a protein which is fundamental to guarantee the restoration and regeneration of the liver after a transplant or hepatic surgery.
A new University of Wisconsin Oshkosh analysis of raptor teeth published in the peer-reviewed journal Palaeogeography, Palaeoclimatology, Palaeoecology shows that Velociraptors and their kin likely did not hunt in big, coordinated packs like dogs.
The raptors (Deinonychus antirrhopus) with their sickle-shaped talons were made famous in the 1993 blockbuster movie Jurassic Park, which portrayed them as highly intelligent, apex predators that worked in groups to hunt large prey.
Volume 11, Issue 18 of @Oncotarget Clinical implications of chromatin accessibility assessed by ATAC-seq profiling in human cancers especially in a large patient cohort is largely unknown.
Silica optical fibers exhibit intrinsic features such as ultralow loss, a high damage threshold, and a small mode field, enabling the possibility of long-haul communications and sensing, and have greatly changed our daily living and working styles. The advance of fibers also gives birth to nonlinear fiber optics due to the long interaction length and high power density in the fiber core. However, the lowest-order nonlinear effects in optical fibers originate from the third-order nonlinear susceptibility, which requires extremely high peak power.
Flight feathers are amazing evolutionary innovations that allowed birds to conquer the sky. A study led by Matthew Towers (University of Sheffield, UK) and Marian Ros (University of Cantabria, Spain) and published in the journal Development now reveals that flight feather identity is established thanks to Sonic hedgehog - a signalling molecule well-known for giving the digits of the limb their different identities (so that your thumb is different from your pinky, for example).
New research has found that children born with a cleft lip, either with or without a cleft palate, are not likely to be genetically predisposed to do less well at school than their peers. The study by the Cleft Collective research team at the University of Bristol is published today [6 May] in the International Journal of Epidemiology.
Parents should not feel pressured to make their young children undertake structured learning or achieve specific tasks, particularly during lockdown. A new study of children under the age of two has found that parents who take a more flexible approach to their child's learning can - for children who were easy babies - minimise behavioural problems during toddlerhood.
The USTC team led by Prof. YU Shuhong from University of Science and Technology of China, collaborating with Prof. WU Jianbo from Shanghai Jiao Tong University, has shed new lights on the topic of solid-phase ion migration. Researchers demonstrated a unique in-situ strategy for visualizing the dynamic solid-phase ion migration between nanostructures with nanogap at the atomic scale. The research article entitled "Real-Time Visualization of Solid-Phase Ion Migration Kinetics on Nanowire Monolayer" was published in Journal of the American Chemical Society on April 29th.
BUFFALO, N.Y. - A group of researchers at the University at Buffalo have published a paper that clarifies certain cellular mechanisms that could lead to improved outcomes in patients with globoid cell leukodystrophy, commonly known as Krabbe disease.
The paper, titled "Macrophages Expressing GALC Improve Peripheral Krabbe Disease by a Mechanism Independent of Cross-Correction," was published today (May 5) in the journal Neuron.
WASHINGTON, May 5, 2020 -- Quantum photonics involves a new type of technology that relies on photons, the elementary particle of light. These photons can potentially carry quantum bits of information over large distances. If the photon source could be placed on a single chip and made to produce photons at a high rate, this could enable high-speed quantum communication or information processing, which would be a major advance in information technologies.
Girls and young women shouldn't spend a lot of time editing selfies for social media because it negatively influences their thoughts about their looks, according to a new Flinders University publication.
In a study published in Body Image, Flinders University psychology researchers asked 130 women aged 18 to 30 to view Instagram snaps of thin and average sized women, before analysing their selfie habits.
They found that the longer the women took to edit and post selfies, the worse their mood and dissatisfaction about their facial appearance.
