Tracking the atomic pathways by in-situ liquid cell TEM

Recently, platinum-containing core-shell structures with tunable magnetic and catalytic properties have attracted intensive attentions and offered a wide range of applications. To date, their synthetic routes are mostly based ...

Leaking away essential resources actually helps cells grow

Experts have been unable to explain why cells, from bacteria to humans, leak essential chemicals necessary for growth into their environment. New mathematical models reveal that leaking metabolites—substances involved in ...

Fungus produces active agent in a medicinal herb

Tatarinow's aster is used in traditional Chinese medicine to treat a number of ailments; the plant contains an active ingredient known as astin—and it is this agent which cancer researchers are now investigating. However, ...

A 'rheostat' for cancer signals

WNT signaling pathways play important roles in cell growth, development and cancer. The classical or "canonical" WNT pathway and its atypical, "non-canonical" counterpart share a protein called DVL2 that "transduces" or converts ...

A new signaling pathway for mTor-dependent cell growth

The activation of mTor complex 1 in the cell is central to many vital processes in the body such as cell growth and metabolism. Overactivity of this signaling pathway can result in diseases such as in diabetic insulin resistance ...

Frog fungus fights back

Amphibian populations have been declining around the world for more than 40 years. One culprit is the fungus B. dendrobatidis, which causes the disease chytridiomycosis.
