Researchers used metal-organic frameworks (MOFs) enhanced with a green tea phytochemical coating to target human prostate cancer cells for the first time.
The new method for deploying the genetic snipping tool directly into target cells is a big step towards more effective, safer and cheaper gene therapy with treatment potential for multiple genetic disorders.
Researchers at the University of Helsinki, Aarhus University and the University of Manchester have investigated the link between the socio-economic position of parents and the risk of children developing mental disorders later in life.
Prevalent piezoelectric materials like barium titanate (BaTiO3) and lead zirconate titanate (PZT) possess high piezoelectric coefficients 20-800 pC/N, which are also ferroelectric. The Curie temperature of those ferroelectrics are mostly far above room temperature, so the change of polarization ΔP upon a strain at room temperature is approximately the same as ΔP0 at 0K.
Abundant. Clean. Flexible. Alluring enough to explain why hydrogen, the most common molecule in the universe happens to have its name as part of an national Hydrogen and Fuel Cell Day. Chosen to signify hydrogen's atomic weight of 1.008, the U.S. Department of Energy's Office of Energy Efficiency and Renewable Energy celebrates advances in hydrogen-use technology every October 8 since 2015. When hydrogen is consumed in a fuel cell (which takes the water molecule H2O and seperates it into oxygen and hydrogen, a process called electrolysis), it only produces water, electricity, and heat.
Although coastlines have widely been proposed as potential corridors of past migration, the occupation of Africa's tropical coasts during the Stone Age is poorly known, particularly in contrast to the temperate coasts of northern and southern Africa. Recent studies in eastern Africa have begun to resolve this, detailing dynamic behavioural changes near the coast of Kenya during the last glacial phase, but studies of Stone Age occupations along western Africa's coasts are still lacking.
Cardiovascular disease is the leading cause of mortality and ischemic heart disease is a major cause of death worldwide. Coronary vessels that nourish the heart develop from three main sources, the endocardium on the inner surface of the hearts blood-filled chambers being one of the major contributors. In normal conditions, the adult heart can no longer generate new blood vessels from the endocardium, because the endocardium-to-coronary vessel transition is blocked by a connective tissue wall beneath the endocardium.
Natural materials like skin, cartilage and tendons are tough enough to support our bodyweight and movements, yet flexible enough that they don't crack easily. Although we take these properties for granted, replicating this unique combination in synthetic materials is much harder than it sounds. Now, scientists at EPFL have developed a new way of making strong, supple composite polymers that more closely mimic materials found in the natural world.
Research led by the Centenary Institute, the University of Technology Sydney and the University of Queensland has shown for the first time a link between chronic obstructive pulmonary disease (COPD), an often fatal lung condition, and the gut microbiome.
The findings, published in the high impact science journal 'Nature Communications', suggests that the gut may be helpful in diagnosing COPD and may also be a potential source of new therapeutic targets to help treat the chronic respiratory disorder.
Stopping the replication of SARS-CoV-2 is likely possible thanks to a compound called EBSELEN: a group of researchers from the Politecnico di Milano has communicated aspects relevant to the blocking of replication mechanism in the New Journal of Chemistry.
Two important aspects of the propagation of a virus are its ability to enter the host's cells, that is, to infect the host, and then to replicate in infected cells.
When it comes to optimizing “longevity fitness” through attention to social, health, and wealth aspects of life, many Americans face intractable inequities based on the color of their skin, where they live, their sex, and who they love. The COVID-19 pandemic has further demonstrated the additional impacts affecting these demographics through the increased number of cases and mortality rates.
A mutation in the CLCN6 gene is associated with a novel, particularly severe neurodegenerative disorder. Scientists from the Leibniz-Forschungsinstitut für Molekulare Pharmakologie (FMP) and the Max Delbrück Center für Molekulare Medizin (MDC), together with an international team of researchers, have now analyzed the effect of a point mutation that was found in three unrelated affected children.
Mangoes, like other orange fruits and vegetables, are rich in beta-carotene and provide antioxidants that may delay cell damage. A new study from researchers at the University of California, Davis, finds eating Ataulfo mangoes, also known as honey or Champagne mangoes, may have another benefit -- reducing facial wrinkles in older women with fairer skin. The study was published in the journal Nutrients.
Materials scientists at Duke University have devised a simplified method for calculating the attractive forces that cause nanoparticles to self-assemble into larger structures.
Reno, Nev. (Nov. 19, 2020) - Climate change and a "thirsty atmosphere" will bring more extreme wildfire danger and multi-year droughts to Nevada and California by the end of this century, according to new research from the Desert Research Institute (DRI), the Scripps Institution of Oceanography at the University of California, San Diego, and the University of California, Merced.
An international research team led by UK scientists has revealed the return of critically endangered Antarctic blue whales to the sub-Antarctic island of South Georgia, 50 years after whaling all but wiped them out. The new study follows recent research that humpback whales are also returning to the region.
