The reasons for our left or right-handedness
A preference for the left or the right hand might be traced back to that asymmetry. (Medical News Today)

Role of rogue protein PAK4 confirmed in pancreatic cancer cells
A new study that confirms the role of a protein called PAK4 in the movement and growth of pancreatic cancer cells could help researchers find new ways to tackle the disease. (Medical News Today)

ELMO1 at the heart of the metastatic process of tumor cells
A group of French and American scientists led by Dr. Géraldine Guasch at the Cancer Research Center in Marseille France (CRCM, INSERM) uncover how aggressive transition zone tumors grow and spread... (Medical News Today)

Food additive found in candy, gum could alter digestive cell structure and function
The ability of small intestine cells to absorb nutrients and act as a barrier to pathogens is "significantly decreased" after chronic exposure to nanoparticles of titanium dioxide, a common food... (Medical News Today)

How cancers trick the immune system into helping rather than harming them
Scientists at Trinity College Dublin have discovered how certain cancers hijack the immune system for their benefit, tricking it into helping rather than harming them. (Medical News Today)

Parkinson's: 'Genetic switch' may play key role in preserving brain cells
Study finds a genetic switch that controls PINK1 and PARKIN genes, defects in which cause mitchondrial dysfunction seen in some forms of Parkinson's. (Medical News Today)

When your eyes override your ears: New insights into the McGurk effect
Seeing is not always believing - visual speech (mouth movements) mismatched with auditory speech (sounds) can result in the perception of an entirely different message. (Medical News Today)

Cancer: New method tags elusive tumors for targeted therapy
Some tumors are difficult to target because their cells have no unique receptors to tag. Now, researchers reveal a way to manually introduce them. (Medical News Today)

Organo-metal compound seen killing cancer cells from inside
Researchers have witnessed - for the first time - cancer cells being targeted and destroyed from the inside, by an organo-metal compound discovered by the University of Warwick. (Medical News Today)
