“‘SDG for a better future’ is not only the theme of our Summer School, but also our shared vision,” Prof. WU Zhaohui, president of Zhejiang University, said at the opening ceremony of the SDG Global Summer School, which was held on August 1 in the format of the metaverse. As part of Z4G, Zhejiang University’s sustainability action plan, the inaugural SDG Summer School in the virtual format is aimed to maximize the University’s positive impact on the youth and the world by enhancing sustain...

The modern lifestyle characterized by excessive nutrition and poverty of exercise contributes to the global epidemic of obesity and type 2 diabetes (T2D). Pancreatic β cell dysfunction, together with insulin resistance, are the main causes for the pathogenesis of T2D. A thorough analysis of the dynamic changes in the number and function of β cells in T2D and the mechanism of β cell dysfunction will provide a theoretical basis and molecular targets for the development of new and more effective...

Hundreds of millions of years ago, microbes and plants might have given insects an evolutionary advantage by passing genes to them through horizontal gene transfer. In a study published in the journal Cell on July 18, researchers report that more than 1,400 genes across 218 insect species, including butterflies and moths, that originated from bacteria, viruses, fungi, and plants.The study argues that these genes might have been essential for insect evolution by allowing them to develop bene...

The guided endogenous mesenchymal stem cells recruitment and angiogenesis through bone implants surface modification are the most essential for proper bone regeneration and enhanced osseointegration. However, most reported studies were conducted to endow implant surface with multiple functionalities via multiple bio-active compounds and complicated strategies. Moreover, our understanding of the regulatory mechanism of surface coatings for vascularization and osteogenesis liaison is incomplete, e...

The bacterial leaf blight disease (BLB) is among the three most devastating pathogens limiting rice production in China. Recent years has witnessed a resurgence of BLB in Zhejiang and other major rice areas in China due to climate change and the changes in the cultivation system. Moreover, there has emerged a new epidemic pattern. These have posed great challenges to the control of BLB. As one of the ten emerging chemical technologies that will change the world in the future, nano-enabled agroch...

The robustness of the developmental process for multicellular organisms suggests a dedicated regulatory program that governs the trajectories of cell-fate decisions. According to Waddington’s epigenetic landscape theory, differentiated cell types arise from an unstable stem / progenitor state and eventually fall into stable cell-fate attractors. The emerging concept of the state manifold derived from single-cell data has further enhanced our understanding of lineage progression. What are the ge...

The vascular network is the primary system for transporting nutrients, oxygen and metabolites. Therefore, angiogenesis, the formation of new blood vessels from pre-existing vessels, is of vital importance to the function of organisms. At the core of angiogenesis are endothelial sprouting and lumen formation. The basic fibroblast growth factor (FGF2) has been recognized as the first proangiogenic molecule, and it facilitates angiogenesis by activating FGF receptor 1 (FGFR1) signaling in endotheli...

Light-emitting diodes (LEDs) have created far-reaching impacts on display and lighting industries. For a LED to emit light, the minimum voltage is widely considered to be equal to the bandgap voltage of the material, in consideration of the energy conservation principle. Reducing the operating voltages of LEDs can save power and improve speed.In recent years, light emission at sub-bandgap voltages (typically 80-100% of the bandgaps) was observed for some emerging classes of LEDs, including organ...
