Fluorescence method detects mercury contamination in fish

Researchers from the University of Burgos (Spain) have developed a fluorescent polymer that lights up in contact with mercury that may be present in fish. High levels of the metal were detected in samples of swordfish and ...

Researchers reconstruct early stages of embryo development

Researchers at the University of Cambridge have managed to reconstruct the early stage of mammalian development using embryonic stem cells, showing that a critical mass of cells – not too few, but not too many – is needed ...

New device for rapid, mobile detection of brain injury

When accidents that involve traumatic brain injuries occur, a speedy diagnosis followed by the proper treatment can mean the difference between life and death. A research team, led by Jason D. Riley in the Section on Analytical ...

Biologists find a way to lower tumor risk in stem cell therapies

One of the characteristics of embryonic stem cells is their ability to form unusual tumors called teratomas. These tumors, which contain a mixture of cells from a variety of tissues and organs of the body, are typically benign. ...
