Cells are “irritable”: they react when exposed to chemicals. Chemical sensitivity is a property of the simplest forms of life that are endowed with chemical sensors and is also manifest in the most evolved organisms. To detect chemical signals, evolution has provided animals with specific recepto...
Artificial spider silk has emerged as a biobased fiber that could replace some petroleum-based materials that are on the market today. Recent progress made it possible to produce the recombinant spider silk protein NT2RepCT at levels that would make the
Chemical digestion involves the catalytic processing of food in the gastrointestinal (GI) tract by digestive enzymes, aided by co-secreted substances, required to break down the food substances into simpler molecules for absorption. This process is necessary for transport and subsequent metabolic reaction...
Mr Khan and his team have changed my life. My dream has come true and I have a wonderful long-awaited tummy and perfect shape. My husband, children and family have noticed the lift this has had on my spirits. I am more active and I enjoy more outdoor activities and I also love bein...
The Chemistry of Life Processes Institute, Northwestern University, Evanston, IL, USA Thomas V. O’Halloran Contributions C.F. and X.W. performed CueR–TAC complex assembly, cryo-EM data collection and molecular-beacon experiments. C.F. calculated the cryo-EM maps, completed the model building...
As they reveal longer circulation half-life and better biocompatibility, they have demonstrated themselves as a promising T1 candidate for MRI. The focus of this review will be on the preparation and fabrication of T1 contrast agents that contain mainly paramagnetic manganese and iron ions, with ...
Although these models are closer to the intestinal anatomy and physiology than conventional monocultures, the most used model for the evaluation of the exposure to NBMs is still the culture of Caco-2 cells on porous membrane inserts. In these conditions the cells rapidly differentiate into an inte...

Olfactory sensory neurons within the olfactory epithelium are responsible for detecting odors, and in mice and humans they are continuously regenerated from globose progenitors throughout life (Durante et al., 2020; Schwob et al., 2017). The olfactory epithelium also contains other support and non...
Climatic changes are anticipated to have a detrimental effect on calcifying marine species. Calcareous red algae may be especially vulnerable to seasonal variations since they are common and essential biologically, but there is little research on the morpho-anatomical, and chemical characterization of suc...
