New organic flow battery brings decomposing molecules back to life
After years of making progress on an organic aqueous flow battery, Harvard University researchers ran into a problem: the organic anthraquinone molecules that powered their ground-breaking battery were slowly decomposing over time, reducing the long-term usefulness of the battery.

How to quell a cytokine storm: New ways to dampen an overactive immune system
BRCA—the family of DNA-repair proteins associated with breast, ovarian prostate, and pancreatic cancers—interacts with a multipart, molecular complex that is also responsible for regulating the immune system. When certain players in this pathway go awry, autoimmune disorders, like lupus, can arise. Now, researchers in the Perelman School of Medicine at the University of Pennsylvania and colleagues at the University of Leeds, United Kingdom, have deciphered the structure of the complex and have found new molecular targets for fighting autoimmunity. Their findings are published this week in Nature.

HGF-inhibitory macrocyclic peptide—mechanisms and potential cancer theranostics
Hepatocyte Growth Factor (HGF) is a protein that acts as a cell growth factor. By binding to its receptor protein MET on the cell membrane, it exerts its physiological functions such as proliferation and migration of cells, as well as tissue repair and regeneration. For a cancer tissue however, since it promotes invasion and survival of cancer cells, it can play roles in cancer metastasis and acquisition of resistance against anti-cancer drugs. HGF exists in a precursor form, inactive HGF, in various tissues, but the precursor is converted into active HGF only in the vicinity of cancer cells. Because of this reason, molecules that selectively detect/inhibit active HGF are highly desirable but have not been described so far.
