The neural mechanisms that inhibit slow muscle activity during fast swimming in fish
Using zebrafish larvae, biologists have discovered neural mechanisms that suppress slow muscle activity in fish swimming at high speeds.

A better understanding of the von Willebrand Factor's A2 domain
A team of researchers is working to characterize the mysterious protein known as the Von Willebrand Factor (vWF). In a recent article, they advance experimental data for the shear-induced extensional response of vWF, using a microfluidic device and fluorescence microscopy.

Scientists use molecular tethers, chemical 'light sabers' for tissue engineering
Researchers have unveiled a new strategy to keep proteins intact and functional in synthetic biomaterials for tissue engineering. Their approach modifies proteins at a specific point so that they can be chemically tethered to the scaffold using light. Since the tether can also be cut by laser light, this method can create evolving patterns of signal proteins throughout a biomaterial scaffold to grow tissues made up of different types of cells.

Dead cells disrupt how immune cells respond to wounds and patrol for infection
Immune cells prioritize the clearance of dead cells overriding their normal migration to sites of injury. A research paves the way for new therapies to manipulate how white blood cells get to and are kept at sites of injuries during healing.

Staying in shape: How rod-shaped bacteria grow long, not wide
Researchers show how the rod-shaped bacteria Bacillus subtilis maintains its precise diameter while growing end to end.

SABER tech gives DNA and RNA visualization a boost
A collaborative research team has now developed 'Signal Amplification by Exchange Reaction' (SABER), a highly programmable and practical method that significantly enhances the sensitivity as well as customization and multiplexing capabilities of FISH analysis.

Virulence factor of the influenza A virus mapped in real-time
Researchers have used high-speed microscopy to investigate native structure and conformational dynamics of hemagglutinin in influenza A.

Cell polarity: An aurora over the pole
Recent research has identified the master switch that triggers the symmetry breaking process in the zygotes of the nematode worm, Caenorhabditis elegans.

Researchers unravel mechanisms that control cell size
A multidisciplinary team has provided new insight into underlying mechanisms controlling the precise size of cells. The researchers found that 'the adder,' a function that guides cells to grow by a fixed size from birth to division, is controlled by specific proteins that accumulate to a threshold.

Designing biological movement on the nanometer scale
Synthetic proteins have now been created that can move in response to their environment in predictable and tunable ways. These proteins can use their movement to disrupt lipid membranes in cells. They show promise as tools for drug delivery, and might eventually rival the efficiency of virus vehicles, but without some of their drawbacks.
