A cyborg sensor that could unlock anesthesia's secrets

(Phys.org) —Almost every biological process involves sensing the presence of a certain chemical. Finely tuned over millions of years of evolution, the body's different receptors are shaped to accept certain target chemicals. ...

Researchers identify key pathway for plant cell growth

For plants, the only way to grow is for cells to expand. Unlike animals, cell division in plants happens only within a tiny region of the root and stem apex, making cell expansion the critical path to increased stature.

Researchers present a shiny new tool for imaging biomolecules

At the heart of the immune system that protects our bodies from disease and foreign invaders is a vast and complex communications network involving millions of cells, sending and receiving chemical signals that can mean life ...

DNA nanorobot triggers targeted therapeutic responses

Researchers uncover secrets of 'miracle fruit'

(PhysOrg.com) -- Though not very well known in the United States, at least until the past few years, the miracle fruit is a cranberry like fruit that has the unique property of being able to make acidic or bitter foods taste ...

Scientists reveal how snakes 'see' at night

Scientists revealed Sunday for the first time how some snakes can detect the faint body heat exuded by a mouse a metre (three feet) away with enough precision and speed to hunt in the dark.

How cells navigate in messy environments

Your cells need to get around. For example, immune cells must roam around your body to locate sites of infection, and neurons must migrate to specific positions in the brain during development. But cells do not have eyes ...
