To a large extent, DNA methylation, which regulates vital cell functions, is still a big mystery to the scientific world. Now,, scientists have developed a method to quickly couple methylation enzymes to their respective methylation pattern. This finding could become essential for successful gene engineering in many species.
National or other emissions inventories of greenhouse gases that are used to develop strategies and track progress in terms of emissions reductions for climate mitigation contain a certain amount of uncertainty, which inevitably has an impact on the decisions they inform. IIASA researchers contributed to several studies in a recently published volume that aims to enhance understanding of uncertainty in emissions inventories.
Many companies are working on materials that would be as light and resistant as plastic but at the same time fully biodegradable. What if they could be made from.....rubbish? A modern, ecological (waste-free -- the conversion of raw material to product reaches 100%) and economical (does not require high temperatures or expensive catalysts) method of obtaining organic monomers is coming into being at the IPC PAS.
DGIST Professor Jaeheung Cho in the Department of Emerging Materials Science secured materials that lead aldehyde deformylation reaction. Confirmed the nucleophilic reactions by biomimetic materials... Expects to bring positive impacts on related research.
With billions of years of practice, nature has created the most energy efficient machines. One, [Ne-Fi] hydrogenase, is the oldest in microorganisms and is used for hydrogen metabolism. Using Fourier transform infrared spectroscopy, researchers at Nara Institute of Science and Technology (NAIST) reveal the proton transfer pathway of this enzyme, a discovery expected to contribute to new biofuel cells.
Scientists at Johns Hopkins have successfully created personalized digital replicas of the upper chambers of the heart and used them to guide the precise treatment of patients suffering from persistent irregular heartbeats. These simulations accurately identified where clinicians need to destroy tissue to restore the heart's normal rhythm.
Detrimental economic effects of global warming are likely to go beyond those being discussed in policy circles -- particularly for wealthier nations, say researchers. Study suggests that 7% of global GDP will disappear by 2100 as a result of business-as-usual carbon emissions -- including over 10% of incomes in both Canada and the United States.
Reparative medicine scientists at the Fralin Biomedical Research Institute discovered a new compound that could shield heart tissue before a heart attack, as well as preserve healthy cells when administered after a heart attack. The findings are in the Journal of the American Heart Association.
Researchers at McMaster University who rush in after storms to study the behaviour of spiders have found that extreme weather events such as tropical cyclones may have an evolutionary impact on populations living in storm-prone regions, where aggressive spiders have the best odds of survival.
Harvard researchers have developed a new DNA-nanotechnology-based approach called Immuno-SABER, that combines the protein targeting specificity of commonly available antibodies with a DNA-based signal-amplification strategy that enables the highly multiplexed visualization of many proteins in the same sample with pre-programmable and tunable fluorescence signals at each target site.
