New technology protects authenticity of engineered cell lines

Advances in synthetic biology and genome editing have led to a growing industry to develop customized cell lines for medical research. These engineered cell lines, however, can be vulnerable to misidentification, cross-contamination ...

Ocean life may adapt to climate change, but with hidden costs

Suppose that we could watch twenty generations of whales or sharks adapting to climate change—measuring how they evolve and how their biology changes as temperatures and carbon dioxide levels rise. That could tell us a ...

Fuzzy molecular threesome is basis of gene expression

Specific nuclear proteins act as a glue to pack genetic material in an absurdly small space in the human body. Proteins "gluing" DNA are called linker histones, and hold their secret in their electric charge. They are strongly ...

There may be more bird species in the tropics than we know

Study of a perky little bird suggests there may be far more avian species in the tropics than those identified so far. After a genetic study of the White-crowned Manakin, scientists say it's not just one species and one ...
