If you feel that two gold rings are old-fashioned, you can ask a goldsmith to re-make a pair of rings by melting the old ones under high temperature. However, you are bothered by a twinge of regret after the rings are melted into liquid. Is it possible to get back the two original gold rings?The answer is self-evident. Even if the remade gold rings look exactly identical to the former ones in appearance, corresponding internal components have been disrupted and re-distributed randomly.For ordina...

Photosynthesis is a process used by plants and other organisms to convert light energy into chemical energy that can later be released to fuel the organisms’ activities. It is largely responsible for producing and maintaining the oxygen content of the Earth’s atmosphere, and supplies most of the energy necessary for life on the Earth. The reaction center (RC)—the core of the photosynthetic apparatus where charge separation occurs—is thought to have originated a single time and diverged, yieldi...

A UV-activated exceedingly adhesive hemostatic biomimetic hydrogel stops high-pressure bleeding of beating heart in 20s without suture.Yesterday we reported a recent work from the Department of Chemistry on flexible zeolite-cotton fiber to stop external bleeding. To treat internal bleeding, the research team led by Prof. OUYANG Hongwei from the School of Medicine designs a biomimetic tissue adhesive product that can polymerize and adhere within seconds, and strongly bond to wet bi...

A team headed by Prof. GAO Chao, director of Zhejiang University’s Institute of Polymer Science, developed a new polar-inverse strategy (PIS) for scalable synthesizing sequence-defined polymers with positively charged backbone by alternately processing Menschutkin reaction and Cu-catalyzed azide–alkyne cycloaddition (CuAAC) reaction.“Our research enables cost-effective large-scale production of multifunctional positively charged polymers, paving the way to their applied research and real appli...

When a waiter warmly brings you drinks and recommends something for you, do you keep smiling but secretly hope him to leave me alone?When your friends throw a surprise party for you or send you birthday presents, do you feel touched, whilst worrying about repaying the kindness?In many cases, offering consumers favors generates positive effects in sales. However, to some, such practice arouses discomfort. A study shows that considerable individual differences exist in feeling anxious in situation...

The research team headed by DING Nai at the College of Biomedical Engineering and Instrument Sciences published an article entitled “Eye Activity Tracks Task-Relevant Structures during Speech and Auditory Sequence Perception” in the December 18 issue of Nature Communications. Their results show that your eye movements may tell if you are interested when listening to a speech.In daily life, a lot of things call for our attention. For example, we need to listen attentively in class, st...

The research team, led by Prof. YUAN Huiqiu from the Center for Correlated Matter and Department of Physics, Zhejiang University, obtained empirical evidence for the existence of Weyl fermions in the heavy fermion semimetal, thereby providing a novel platform for the exploration of the interplay between topology and strong electronic correlations. Their findings are published in the November 5 issue of the journal of Nature Communications.  We can use two common daily objects to explai...

GUO Fang, a researcher in the Department of Neuroscience of School of Medicine, identifies a neural circuit of Drosophila linking circadian neuron APDN1 with the sleep center ellipsoid body EB-R2. This study provides crucial clues to understanding the connection mechanism between the circadian clock and the sleep regulation.Researchers forecast that in the future, light sleepers may cure insomnia by taking certain medicine so as to have better-quality sleep. It is also surmised that with mo...

Mobilized resistance to colistin is evolving rapidly and its global dissemination poses a severe hazard to human health and safety. Transferable colistin resistance gene, mcr-3, first identified in Shandong, China, has already been found in several countries in multidrug-resistant human infections. Antimicrobial resistance: global report on surveillance 2014 issued by WHO points out that over 1 million patients died of antimicrobial resistance (AMR) all over the world in 2013. A team led by...

Portable electronic devices, say the smartphone and the laptop, have become a necessity in daily life. The expeditious development of these devices benefits enormously from renewable and environmentally-friendly batteries. As such compact and handy wearables as sports bracelets are becoming all the rage, it is top on the list of priorities that efficient, clean and sustainable electrical energy should be made available.Recently, a research team led by Dr. ZHU Zhiyuan from ZJU’s Ocean College&nb...
