Rearranging the cell’s skeleton
Cell biologists at Johns Hopkins have identified key steps in how certain molecules alter a cell’s skeletal shape and drive the cell’s movement.

Circular RNAs more common than previously thought
In the classical model of gene expression, the genetic script encoded in our genomes is expressed in each cell in the form of RNA molecules, each consisting of a linear string of chemical ‘bases’.

Plant enzyme works double shifts
A team of researchers led by Michigan State University has discovered an overachieving plant enzyme that works day and night shifts.

Detailed picture of how myoV ‘walks’ along actin tracks
A new study uses state-of-the-art fluorescence microscopy to provide a striking 3-D picture of how class V myosins (myoV) ‘walk’ along their actin track.

The secret life of proteins
Researchers at the Northwestern University Feinberg School of Medicine have identified a new and unusual role for a key player in the human immune system.

Mutation drives viral sensors to initiate autoimmune disease
A new study uses a mouse model of a human autoimmune disease to reveal how abnormal regulation of the intracellular sensors that detect invading viruses can lead to autoimmune pathology.

Protein in the brain could be a key target in controlling Alzheimer’s
A protein recently discovered in the brain could play a key role in regulating the creation of amyloid β, the major component of plaques implicated in the development of Alzheimer’s disease, according to researchers.

Scientists discover new clue to the chemical origins of life
Organic chemists at the University of York have made a significant advance towards establishing the origin of the carbohydrates that form the building blocks of life.

How cells dispose of their waste
Defective proteins that are not disposed of by the body can cause diseases such as Alzheimer’s or Parkinson’s.

New study sheds light on evolutionary origin of oxygen-based cellular respiration
Researchers at the RIKEN SPring-8 Center in Harima, Japan have clarified the crystal structure of quinol dependent nitric oxide reductase (qNOR), a bacterial enzyme that offers clues on the origins of our earliest oxygen-breathing ancestors.

Why bats, rats and cats store different amounts of fat
Animals differ in the amount of fat they carry around depending on their species, status and sex. However, the causes of much of this variation have been a mystery.

How α-synuclein interacts with cell membranes in Parkinson’s disease
The accumulation of α-synuclein, a small, negatively charged protein, in neural cells, is one of the hallmarks of Parkinson’s disease.

Essential protein for the formation of new blood vessels identified
New research explains how cells regulate their bonds during the development of new blood vessels.

The ‘drunken sailor’ gait of dynein
Just like people, some proteins have characteristic ways of ‘walking’, which (also like human gaits) are not so easy to describe.

Ultra short telomeres linked to osteoarthritis
Telomeres, the very ends of chromosomes, become shorter as we age.
