Open AccessCritical role of slags in pitting corrosion of additively manufactured stainless steel in simulated seawater
Pitting corrosion in seawater is one of the most difficult forms of corrosion to identify and control. A workhorse material for marine applications, 316L stainless steel (316L SS) is known to balance resistanc...

Open AccessNanoporous gold nanoleaf as tunable metamaterial
We have studied optical properties of single-layer and multi-fold nanoporous gold leaf (NPGL) metamaterials and observed highly unusual transmission spectra composed of two well-resolved peaks. We explain this...

Open AccessBMP restricts stemness of intestinal Lgr5+ stem cells by directly suppressing their signature genes
The intestinal epithelium possesses a remarkable self-renewal ability, which is mediated by actively proliferating Lgr5+ stem cells. Bone morphogenetic protein (BMP) signalling represents one major counterforce t...

The non-muscle-myosin-II heavy chain Myh9 mediates colitis-induced epithelium injury by restricting Lgr5+ stem cells
Lgr5+ stem cells are crucial to gut epithelium homeostasis, and therapies targeting these cells hold promise for treatment of gastrointestinal diseases. Here we report that the non-muscle-myosin-II (NMII) heav...

Phylogeny of SARS-CoV as inferred from complete genome comparison
SARS-CoV, as the pathogeny of severe acute respiratory syndrome (SARS), is a mystery that the origin of the virus is still unknown even a few isolates of the virus were completely sequenced. To explore the gen...
