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 ...

A better way to design fusion protein drugs

New software developed at A*STAR could help scientists design sophisticated biopharmaceutical drugs that demand the joining of proteins together. The tool, which is freely available online, allows researchers and drug developers ...

Protein recycling machine visualized

Howard Hughes Medical Institute (HHMI) scientists have new structures of an essential cellular recycling machine that depict its structure with near atomic-level detail. The structures, which show a protein called NSF alone ...

Laser pulses reveal DNA repair mechanisms

A new straightforward method enables monitoring the response of nuclear proteins to DNA damage in time and space. The approach is based on nonlinear photoperturbation.
