Microscopic muscles: How non-muscle cells find the strength to move
Researchers have described, for the first time, the ordered arrangement of myosin-II filaments in actin cables of non-muscle cells.

Malaria parasites 'walk through walls' to infect humans
Researchers have identified proteins that enable deadly malaria parasites to 'walk through cell walls' -- a superpower that was revealed using the Institute's first insectary to grow human malaria parasites. The research has identified two parasite proteins that are the key to this superpower. The proteins could be targeted to develop much-needed antimalarial drugs or vaccines.

Discovery of a new regulatory protein provides new tool for stem cell engineering
Bioengineers have discovered a protein that regulates the switch of embryonic stem cells from the least developed 'naïve' state to the more developed 'primed' state. This discovery sheds light on stem cell development at a molecular level.

A molecular on/off switch for CRISPR
Scientists now reveal how viruses disable bacterial immune systems. For many bacteria, one line of defense against viral infection is a sophisticated RNA-guided "immune system" called CRISPR-Cas. At the center of this system is a surveillance complex that recognizes viral DNA and triggers its destruction. However, viruses can strike back and disable this surveillance complex using "anti-CRISPR" proteins, though no one has figured out exactly how these anti-CRISPRs work -- until now.

'Skin-and-bones' mechanism underlying zebrafish fin regeneration discovered by researchers
Biologists have figured out how zebrafish perfectly regenerate amputated fins with a precisely organized skeleton.

Chlamydia: How bacteria take over control
To survive in human cells, chlamydiae have a lot of tricks in store. Researchers have now discovered that the bacterial pathogens also manipulate the cells' energy suppliers in the process.

Zika virus protein mapped to speed search for cure
A team of scientists has mapped a key protein that causes the Zika virus to reproduce and spread. Results of this study advance efforts to find drugs in fight against the disease, say scientists.

Friction shapes zebrafish embryos
The biochemical signals that give an embryo its shape have been studied extensively. The role of mechanical forces on the other hand is the subject of a new study. Here the researchers show that friction between moving tissues generates force. This force shapes the nervous system of the zebrafish embryo.

Cell biology: The quickest route to the tip for protein transport
According to a new theoretical model, in cell protrusions and cargo-transporting motor proteins often get in each other's way. The upshot is that freely diffusing proteins reach the leading edge faster.
