Cellular mechanical forces may initiate angiogenesis

Pericytes, the contractile cells surrounding capillaries, may use mechanical forces to initiate angiogenesis, the "sprouting" of new blood vessels, according to researchers at Tufts University School of Medicine (TUSM) and ...

Harnessing the possibilities of the nanoworld

Scientists have long suspected that the way materials behave on the nanoscale – that is when particles have dimensions of about 1–100 nanometres – is different from how they behave on any other scale. A new paper in ...

What makes plant cell walls both strong and extensible?

A plant cell wall's unique ability to expand without weakening or breaking—a quality required for plant growth—is due to the movement of its cellulose skeleton, according to new research that models the cell wall. The ...

Small evolutionary shifts make big impacts, study finds

(PhysOrg.com) -- In the developing fetus, cell growth follows a very specific schedule. In the eye's retina, for example, cones -- which help distinguish color during the day -- develop before the more light-sensitive rods ...

Sea squirt cells shed light on cancer development

Specialized structures used by cancer cells to invade tissues could also help them escape protection mechanisms aimed at eliminating them, a UA-led research team has discovered.

Screening technique uncovers five new plant activator compounds

A new high-throughput screening technique developed by researchers at the RIKEN Plant Science Center (PSC) has been used to uncover five novel immune-priming compounds in Arabidopsis plants. Discovery of the compounds, which ...
