Researchers discover crucial step in creating blood stem cells

A microbial sensor that helps identify and fight bacterial infections also plays a key role in the development of blood stem cells, providing a valuable new insight in the effort to create patient-derived blood stem cells ...

Researchers investigate fighting tumors with magnetic bacteria

Scientists around the world are researching how anti-cancer drugs can most efficiently reach the tumors they target. One possibility is to use modified bacteria as "ferries" to carry the drugs through the bloodstream to the ...

3-D printing of biological tissue

The future of medicine is biological – and scientists hope we will soon be using 3-D-printed biologically functional tissue to replace irreparably damaged tissue in the body. A team of researchers from the Fraunhofer Institute ...

Bats use blood to reshape tongue for feeding

Nectar-feeding bats and busy janitors have at least two things in common: They want to wipe up as much liquid as they can as fast as they can, and they have specific equipment for the job. A study in the Proceedings of the ...

Cell biology: Flushing out fats

The Wip1 protein is important for survival, but mutations that inactivate it carry some surprising features. "A lack of Wip1 results in an excessive immune reaction to infectious organisms, in some cases killing the host," ...

Feedback loop maintains basal cell population

Notch – the protein that can help determine cell fate – maintains a stable population of basal cells in the prostate through a positive feedback loop system with another key protein – TGF beta (transforming growth factor ...

Pressurized vascular systems for self-healing materials

Artificial microvascular systems for self-repair of materials damage, such as cracks in a coating applied to a building or bridge, have relied on capillary force for transport of the healing agents. Now, researchers at the ...
