Study examines what microorganisms on Mars would need to survive

No life has yet been found on Mars, but it is exciting to explore the circumstances under which it might be possible. A team led by the Technical University of Berlin (TU Berlin) with the Leibniz Institute of Freshwater Ecology ...

Gene network illuminates stress, mutation and adaptation responses

For much of her professional life, Dr. Susan Rosenberg has studied the puzzling response of bacteria to stress and the mutations that result. In the current issue of the journal Science, she puts together the pieces of that ...

Living cells behave like fluid-filled sponges

Animal cells behave like fluid-filled sponges in response to being mechanically deformed according to new research published today in Nature Materials.

A protein that can mean life or death for cells

Each cell in an organism has a sensor that measures the health of its "internal" environment. This "alarm" is found in the endoplasmic reticulum (ER), which is able to sense cellular stress and trigger either rescue responses ...

Study identifies protein required for cell movement

Both basic scientists and clinicians have an interest in how the cells of our body move. Cells must be mobile in order for organisms to grow, to heal, to transmit information internally, to mount immune responses and to conduct ...

Misfolded proteins: The fundamental problem is aging

Proteins are essential for all biological activities and the health of the cell. Misfolded and damaged proteins spell trouble and are common to all human neurodegenerative diseases and many other age-associated diseases. ...

Widespread misinterpretation of gene expression data

Reproducibility is a major challenge in experimental biology, and with the increasing complexity of data generated by genomic-scale techniques this concern is immensely amplified. RNA-seq, one of the most widely used methods ...
