A multinational team of researchers has identified countries where agriculture's increasing dependence on pollination, coupled with a lack of crop diversity, may threaten food security and economic stability. The study, which was published in the journal Global Change Biology on July 11, 2019, is the first global assessment of the relationship between trends in crop diversity and agricultural dependence on pollinators.
An epigenetic change, a form of DNA control, that deactivates some genes linked to cancer late in human development has been conserved for more than 400 million years, new research led by the Garvan Institute of Medical Research suggests.
EPFL scientists have created the first world map of regions with the highest prevalence of the hepatitis E virus (HEV). They hope that their map - freely available online - will help governments and NGOs design more effective prevention campaigns based on reliable data, particularly when it comes to setting up refugee camps. The scientists' research has just been published in Scientific Reports.
RICHLAND, Wash. July 10, 2019 - The goal of the research, published July 11 in the journal Nature, was to engineer artificial proteins to self-assemble on a crystal surface by creating an exact match between the pattern of amino acids in the protein and the atoms of the crystal. The ability to program these interactions could enable the design of new biomimetic materials with customized colors, chemical reactivity or mechanical properties, or to serve as scaffolds for nano-scale filters, solar cells or electronic circuits.
A newly described form of stress called chromatin architectural defect, or chromatin stress, triggers in cells a response that leads to a longer life. Researchers at Baylor College of Medicine and the Houston Methodist Research Institute report in the journal Science Advances that moderate chromatin stress levels set off a stress response in yeast, the tiny laboratory worm C. elegans, the fruit fly and mouse embryonic stem cells, and in yeast and C. elegans the response promotes longevity.
Scientists have developed an animal model that may provide a path toward improving the diagnosis and treatment of the devastating brain disease chronicled in the bestselling autobiography "Brain on Fire." The book, along with a 2017 movie by the same name, traces newspaper reporter Susannah Cahalan's harrowing descent into the throes of the disease.
TORONTO, July 10, 2019 -- Researchers are hopeful that new strategies could emerge for slowing the growth and recurrence of the most common primary brain cancer in adults, glioblastoma, based on the results of a study published today in Cancer Research.
A multifunctional device that captures the heat shed by photovoltaic solar panels has been developed by KAUST and used to generate clean drinking water as a way to simultaneously generate electricity and water using only renewable energy.
What is "water in the mantle"?
Hydrogen is the most abundant element in our solar system. In the Earth, hydrogen exists as vapor in the atmosphere, water and ice in the ocean, super-critical fluids in the volcanoes and Earth crusts, hydroxyls in hydrous and nominally anhydrous minerals in the Earth's crust and mantle, proton and hydroxyl (OH) in magmas, and hydrogen in metallic iron in the Earth's core.
Terahertz (THz) radiation is a bit like a treasure chest that resists being opened fully. Residing in the electromagnetic spectrum between the infrared and microwave regions, THz radiation combines a range of properties that are ideal with a view to applications. It provides a window to unique spectroscopic information about molecules and solids, it can penetrate non-conducting materials such as textiles and biological tissue, and it does so without ionising -- and hence damaging -- the object, or subject, under study.
