Citrus greening disease was first discovered in Florida in 2005. Since then, production of oranges in the United States for processing has declined by 72 percent between the 2007-2008 growing season and the 2017-2018 growing season, primarily in Florida. The disease was discovered in California in 2012, and now the state is beginning to see a rapid increase of citrus greening disease.

Annually, more than 350,000 children in the world are affected by pediatric cancer. Radiation has improved outcomes dramatically, but the damage caused to healthy tissue can affect the long-term health of a child. While clinicians and radiation specialists design treatments using the most up-to-date information available, there hasn't been a single guiding source of data to make evidence-based decisions that are specific for children. Now, a volunteer international research collaboration is working toward providing evidence-based guidelines for radiation therapy dosing for children.

In Amyotrophic Lateral Sclerosis (ALS), the progressive death of neurons that control body movement leads to paralysis of muscles in the limbs and gradually of the whole body, which ultimately makes it impossible to breathe. ALS is currently untreatable, and its cause is unknown.

An essential preliminary to building and construction or resource extraction is studying the geological structure of the site. One of steps of this process is geophysical investigation. This provides a continuous overview of the geological horizons rather than just data on points: boreholes. The standard methods of geophysics help successfully solve this problem in comparatively simple conditions. Yet the classical direct current methods may lead to serious inaccuracy if we have to investigate geologically complex structures with thin layers of sandy and clayey soils.

Leipzig/Jena/Ilmenau. Mobile apps like Flora Incognita that allow automated identification of wild plants cannot only identify plant species, but also uncover large scale ecological patterns. These patterns are surprisingly similar to the ones derived from long-term inventory data of the German flora, even though they have been acquired over much shorter time periods and are influenced by user behaviour. This opens up new perspectives for rapid detection of biodiversity changes.

Lysophospholipids are phospholipids that have just one fatty acid chain, and in recent years, the role of lysophospholipids in physiology and pathophysiology has attracted attention. Lysophosphatidylethanolamine (LPE) is a type of lysophospholipid that are reportedly present in the brain that consist of many species with different fatty acid chain lengths and degrees of unsaturation. The latest studies in animal models have reported elevated levels of LPE in the brain after traumatic brain injury and cerebral ischemia.

A study by the University of Southampton has shown its LifeLab programme, aimed at improving adolescent health through hands-on learning, significantly increases young people's understanding of what it means to lead a healthy lifestyle.

Anyone who's raised a child or a pet will know just how fast and how steady their growth seems to be. You leave for a few days on a work trip and when you come home the child seems to have grown 10cm! That's all well and good for the modern household, but how did dinosaurs grow up? Did they, too, surprise their parents with their non-stop growth?

Controlling, and mitigating the effects of ice growth is crucial to protect infrastructure, help preserve frozen cells and to enhance texture of frozen foods. An international collaboration of Warwick Scientists working with researchers from Switzerland have used a phage display platform to discover new, small, peptides which function like larger antifreeze proteins. This presents a route to new, easier to synthesise, cryoprotectants.Caption: Using viruses (phage display) to identify the one molecule in a billion (peptide8) that controls the formation of ice.

NEW YORK (May 11, 2021) - A group of scientists say now is the time to talk about reintroducing jaguars (Panthera onca) into the U.S.

DNA is composed of nucleobases represented by the letters A, T, G and C. They form the basis of the genetic code and are present in all living beings. But in a bacteriophage, another base, represented by the letter Z, exists. This exception, the only one observed to date, has long remained a mystery. Scientists from the Institut Pasteur and the CNRS, in collaboration with the CEA, have now elucidated the biosynthesis pathway of this base. This work has been published in the April 30th, 2021 issue of Science.

Extreme weather is harming UK agriculture - but many farmers have not yet made adapting to the effects of the climate emergency a priority, a new study shows.

All farmers who took part in the research said they had experienced or witnessed issues caused by extreme weather such as heavy rain or prolonged dry spells in recent years, and expected these to intensify further.

Ann Arbor, May 11, 2021 - Social isolation among older adults is associated with poor health and premature mortality, but the connection between social isolation and physical functioning is poorly understood. New research generates more robust evidence about the associations between social isolation and physical functioning and how this accelerates over time, reports the American Journal of Preventive Medicine, published by Elsevier.

May 11, 2021 - For patients seen at a urology clinic, patient satisfaction scores vary by insurance status - with higher scores for patients on Medicare and commercial insurance, but lower scores for those on Medicaid, reports a study in Urology Practice®, an Official Journal of the American Urological Associati
