In cosmetics, lipid vesicles, also known as liposomes, effectively transport ingredients through the skin. However, they are also used to encapsulate…
Water eutrophication and the resulting hypoxia is an ever-current issue, not least in connection with summer algal blooms. A more recently acknowledged problem…
Metal nanoparticles have radically different electronic, optical and magnetic properties from their larger states, which makes them useful as materials in new,…
Effective response by key immune cells in the body, called T cells, is crucial for control of many widespread chronic viral infections such as HIV and…
Fibrin, the chief ingredient of blood clots, is a remarkably versatile polymer. On one hand, it forms a network of fibers — a blood clot — that stems the…
Cell size is regulated by the balance of positively and negatively charged ions and other solutes in the fluid inside and outside cells, which in turn prevents…
Scientists at the Technische Universitaet Muenchen (TUM) and Harvard University have thrown the lid off a new toolbox for building nanoscale structures out of…
In view of the shortage of petrochemical resources and climate change, development of CO2-neutral sustainable fuels is one of the most urgent challenges of our…
University of Illinois researchers report that they have assembled a new cancer drug delivery system that, in cell culture, achieves all of the above. The…
Johns Hopkins scientists have tracked down a powerful set of cells in bladder tumors that seem to be primarily responsible for the cancer's growth and spread…
New work by MIT cancer biologists shows that the interplay between two key genes that are often defective in tumors determines how cancer cells respond to…
In a study conducted at the University of Idaho, scientists found that the immune system of the study’s frog species failed to respond to the chytrid fungus…
The REDD1 protein is a critical inhibitor of the mTOR signaling pathway, which controls cell growth and proliferation. The study was published in the August…
Scientists at Imperial College London have created detailed 3D computer models of two fossilised specimens of ancient creatures called Cryptomartus hindi and Eophrynus prestvicii, closely related to modern-day spiders. The study reveals some of the physical traits that helped them to hunt for prey and evade predators. The researchers created their images by using a CT scanning device, which enabled them to take 3,000 x-rays of each fossil. These x-rays were then compiled into precise 3D models, using custom-designed software….
To use hydrogen as a clean energy source, some engineers want to pack hydrogen into a larger molecule, rather than compressing the gas into a tank. A gas flows easily out of a tank, but getting hydrogen out of a molecule requires a catalyst. Now, researchers reveal new details about one such catalyst. The results are a step toward designing catalysts for use in hydrogen energy applications such as fuel cells. Scientists from the Department of Energy's Pacific Northwest National…
It is important to understand what biological mechanisms contribute to an individual's capacity to be resilient under conditions of extreme stress, such as…
