Although many organisms capture and respond to sunlight, enzymes—proteins that catalyze biochemical reactions—are rarely driven by light. Scientists...

当一个碳原子上的四个氢原子被不同的碳基团取代时，就产生了一个全碳季碳立体中心。与相应的叔碳立体中心相比，季碳立体中心的结构更具有多样性和刚性，因此广泛存在于药物分子、...

Bed bugs tuck themselves away into dark, unseen spaces and multiply rapidly, making them difficult to control. That job has gotten even harder i...

Piperlongumine, a chemical compound found in the Indian Long Pepper plant (Piper longum), is known to kill cancerous cells in many tumor types, ...

A class of metal-based anti-viral compounds can shield human cells from viruses and may also trap them to prevent viral spread, new Griffith University research has found.　

After pouring beer into a glass, streams of little bubbles appear and start to rise, forming a foamy head. As the bubbles burst, the released ...

If the CO2content of the atmosphere is not to increase any further, carbon dioxide must be converted into something else. However, as CO2is a v...

Efficient analysis of X-ray diffraction data (XRD) plays a crucial role in the discovery of new materials, for example for the energy systems of...

Scientists at Sanford Burnham Prebys have identified, at an atomic level, how a part of a protein called PLEKHA7 interacts with a cell's membrane to regulate important intercellular communications...

In the summer of 1917 in Barcelona, Picasso worked on four paintings inspired by Ballets Russes, using a similar set of material for all of th...

基于质谱的代谢组学已日益成为天然产物化学成分研究的"利器"。尤其在植物提取物的成分分析中，常常使用靶向代谢组学（targeted metabolomics）方法，这种方法一般先有一个确定的...

Inside your body, cell movement plays a crucial role in many significant biological processes, including wound healing, immune responses and the potential spread of cancer.　

Researchers discovered, while exploring the photomechanical properties of diarylethene, that under irradiation with UV light the crystal of the comp...

类固醇（steroid）是一类具有特定四环结构排列的多环化合物，其生物学功能极为广泛。作为调节认知、免疫、代谢和其他生理过程的重要信号分子，类固醇失调会招致众多疾病，如神经退...

固体材料的表界面是固-气，固-液反应发生的地方，如在异相催化和电化学电极反应等。可控地改变固体材料的界面环境对于调控该类基于固体界面化学的催化反应选择性和活性至关重要。...
