Cell memory mechanism discovered

The cells in our bodies can divide as often as once every 24 hours, creating a new, identical copy. DNA binding proteins called transcription factors are required for maintaining cell identity. They ensure that daughter cells ...

Decoding mystery sequences involved in gene regulation

Every cell in an organism's body has the same copy of DNA, yet different cells do different things; for example, some function as brain cells, while others form muscle tissue. How can the same DNA make different things happen? ...

Tissue in trouble calls in reinforcements to restore health

Northwestern University scientists are the first to discover a cellular process used by animals when a tissue is stressed and in molecular trouble from the expression of misfolded and damaged proteins: The tissue at risk ...

Making ice-cream more nutritious with meat left-overs

Food industries are now turning meat left-over into high-protein content ingredients for food supplements, or to be added to processed food. But a EU-wide regulation covering them is still lacking.

Pig stress syndrome linked to gene defect

Undergoing surgery, even a minor procedure, can be stressful for anyone. But for people who have malignant hyperthermia, a hereditary disease that's triggered by certain drugs used for general anesthesia, it can also be dangerous.

Nano-machines for 'bionic proteins'

Physicists of the University of Vienna together with researchers from the University of Natural Resources and Life Sciences Vienna developed nano-machines which recreate principal activities of proteins. They present the ...

Ractopamine is safe for use in Brazilian pork

Animal scientists in Brazil have found that a small dose of the feed additive ractopamine can boost pork production without changing how pork looks or tastes.

Molecular assembly line brings muscles into shape

Scientists at the Research Institute of Molecular Pathology (IMP) in Vienna, Austria and at the University of Cologne, Germany have discovered the molecular basis underlying the patterned folding and assembly of muscle proteins. ...
