When HIV drugs don't cooperate

The term "synergy" has gained a reputation as an overused buzzword, but it has a quantifiable definition in pharmacology. Two drugs are considered synergistic when their effectiveness when used together is greater than the ...

Sugar-coated nanomaterial excels at promoting bone growth

There hasn't been a gold standard for how orthopaedic spine surgeons promote new bone growth in patients, but now Northwestern University scientists have designed a bioactive nanomaterial that is so good at stimulating bone ...

New link found between sex and viruses

Sexual reproduction and viral infections actually have a lot in common. According to new research, both processes rely on a single protein that enables the seamless fusion of two cells, such as a sperm cell and egg cell, ...

Research describes missing step in how cells move their cargo

Every time a hormone is released from a cell, every time a neurotransmitter leaps across a synapse to relay a message from one neuron to another, the cell must undergo exocytosis. This is the process responsible for transporting ...

Research provides key insight into how cells fuse

Researchers at Johns Hopkins have established a high-efficiency cell-cell fusion system, providing a new model to study how fusion works. The scientists showed that fusion between two cells is not equal and mutual as some ...

Driving membrane curvature

(Phys.org) -- In biological systems, membranes are as important as water. They form the barrier between the inner world, within our cells, where we perform the chemical reactions of life, and the outside environment.

How muscle develops: A dance of cellular skeletons

Revealing another part of the story of muscle development, Johns Hopkins researchers have shown how the cytoskeleton from one muscle cell builds finger-like projections that invade into another muscle cell's territory, eventually ...
