Skin has a remarkable ability to heal itself. But in some cases, wounds heal very slowly or not at all, putting a person at risk for chronic pain, infection and scarring. Now, researchers have developed a self-powered bandage that generates an electric field over an injury, dramatically reducing the healing time for skin wounds in rats. They report their results in ACS Nano.
Immunity plays an immense role in the body's fight against cancer. Every day, the cells of the immune system check all the cells of our body for 'normalcy' and kill the degenerated cells. Sometimes cells hide from the immune system and escape the immunological control, and then a tumor develops. Today, there are many different ways to deal with tumors, but often they prove incurable.
The huge amounts of epigenetic data coming from biological experiments and clinic, machine learning can help in detecting epigenetic features in genome, finding correlations between phenotypes and modifications in histone or genes, accelerating the screen of lead compounds targeting epigenetics diseases and many other aspects around the study on epigenetics, which consequently realizes the hope of precision medicine.
Stanford researchers have identified the GPS locations and sizes of almost all US solar power installations from a billion images. Using the data, which is public, they identified factors that promote the use of solar energy and those that discourage it.
Researchers at the University of Washington have genetically modified a common houseplant to remove chloroform and benzene from the air around it.
Osaka University researchers revealed that culturing human induced pluripotent stem cells with different isoforms of the extracellular component laminin led to the creation of cells specific to different parts of the eye, including retinal, corneal, and neural crest cells. They showed that the different laminin variants affected the cells' motility, density, and interactions, resulting in their differentiation into specific ocular cell lineages. Cells cultured in this way could be used to treat various ocular diseases.
CRISPR allows scientists to precisely target and edit DNA within living cells, which could help them correct anomalies that cause inherited diseases. A UD Team has now developed a method to use CRISPR/Cas9 technology to set off a cascade of activities in cells, a phenomenon known as conditional gene regulation.
A new study published in Nature Ecology and Evolution presents a novel approach to identify optimal priority areas for restoration, considering multiple criteria such as biodiversity conservation, climate change mitigation and reduction of costs. In a context of multiple local, national and global targets for ecosystem restoration, the study presents a flexible tool capable of increasing restoration cost-effectiveness by up to eight times.
A team of researchers at the New York University Tandon School of Engineering and NYU Center for Neural Science has solved a longstanding puzzle of how to build ultra-sensitive, ultra-small electrochemical sensors with homogenous and predictable properties by discovering how to engineer graphene structure on an atomic level. The researchers detail their study in a paper published today in the journal Advanced Materials.
Enantiomeric molecules resemble each other like right and left hands. Both variants normally arise in chemical reactions. But frequently only one of the two forms is effectual in biology and medicine. Hitherto, completely converting this mixture into the desired enantiomer was deemed impossible. Deploying a photochemical method, a team from the Technical University of Munich (TUM) has now achieved this feat.
