Flexible throughout life by varying numbers of chromosome copies

Baker's yeast is a popular test organism in biology. Yeasts are able to duplicate single chromosomes reversibly and thereby adapt flexibly to environmental conditions. Scientists from the Luxembourg Centre for Systems Biomedicine ...

Building blocks of life came from deep Earth

The rise of the first complex life depended on vital metals brought up to the Earth's surface from far below in vast granite deposits, a new study argues.

Synthetic cells used to bioengineer new forms of silica

(Phys.org) -- Scientists do not fully understand how nature uses proteins to develop new materials and minerals, but learning more about the natural processes could lead to bioengineering methods such as the biological synthesis ...

Acquired traits can be inherited via small RNAs

Columbia University Medical Center (CUMC) researchers have found the first direct evidence that an acquired trait can be inherited without any DNA involvement. The findings suggest that Lamarck, whose theory of evolution ...
