举例来说,UV照射和许多其他因素都可能导致DNA链断裂。 为了确保自己的生存和增殖,细胞采取了一些修复损伤的措施。虽然DNA修复一直是研究的热点,但人们对这一基础机制仍然知之甚少。洛克菲勒大学的研究人员通过自己开发的新技术,揭示了这一过程的关键一步。这项研究发表在九月七日的Nature Chemical Biology杂志上。 DNA双...
Engineering transverse cell deformation of bamboo by controlling localized moisture content Bamboo’s native structure, defined by the vertical growth pattern of its vascular bundles and parenchyma cell tissue, limits its application in advanced engineering materials. Here the authors show a method that ...
Capping the MXene in eutectic molten salt Constructing ordered triatomic-layer borate polyanion terminations in MXenes substantially enhances their chemical stability and electrochemical energy storage. The development of such ordered terminations with complex configurations largely expands the design space for...
Alpha Lipoic Acidis an antioxidant made by the body; found in every cell, its primary function is to aid in the conversion of glucose into energy. Alpha Lipoic Acid has been shown to combat free radicals as both a fat and water soluble antioxidant, thus making it work more efficiently thro...
Pentasialylated glycans are complex and unusual structures that have been rarely reported in the literature63,64,65,66. Their detection and characterization with LC-MS methods remain difficult due to MS-incompatible high salt eluents typically used in anion exchange chromatography and the detection of...
Plants and animals rely on this passive transfer to extract pure water from salt, brackish, and contaminated water sources. Mimicking osmosis may lead to scalable technologies for producing clean drinking water that can be deployed globally. Aquaporin A/S uses osmosis in its low-energy water ...

Key studies provided insights into immune mechanisms, the role of the gut microbiota, the adverse effects of perivascular fat and inflammation on the vasculature, and the contribution of rare variants in renin–angiotensin–aldosterone system genes to salt sensitivity. Ernesto L. Schiffrin News & ...
Electrochemically induced amorphous-to-rock-salt phase transformation in niobium oxide electrode for Li-ion batteries Intercalation-type metal oxides are promising anodes for Li-ion batteries but suffer from low energy and power density together with cycling instability. A nanostructured rock-salt Nb2O5...
