New key finding in neurodevelopment

A longstanding puzzle in neurodevelopment may have yielded up a key secret. A team led by scientists at Weill Cornell Medical College says they have determined how events at the very tips of the developing neuron's long, skinny axon affect gene transcription back in the cell's distant nucleus.

Many Aussies would take a test for dementia

According to a new report, by the year 2050 as many as 730,000 Australians will be suffering from some form of dementia and almost three quarters of Australians say if such a test existed to show if they were going to develop some form of dementia, they would take it.

Factors associated with exceptionally long life

A healthy lifestyle during the early elderly years—including weight management, exercising regularly and not smoking—may be associated with a greater probability of living to age 90 in men, as well as good health and physical function, according to a report in the February 11 issue of Archives of Internal Medicine, one of the JAMA/Archives journals.

Prion infection of neurons increases the free cholesterol content in cell membranes

A new study published in the online open access journal BMC Biology suggests that disturbances in membrane cholesterol may be the mechanism by which prions cause neurodegeneration and could point to a role for cholesterol in other neurodegenerative diseases.

New insight into how iron gets deposited in the brain to cause some forms of Parkinson's and Alzheimer's

Researchers at the University of Warwick and the Indian Institute of Technology Kanpur have discovered that the mechanism that we rely on to transport iron safely through our blood stream can, in certain circumstances, collapse into a state which grows long worm-like "fibrils" banded by lines of iron rust.

New Parkinson's disease research points to serotonin

For most people with Parkinson's disease, the only relief from the tremors, rigidity and impaired movement associated with the progressive loss of their motor skills is a drug called L-DOPA. But as the disease progresses, L-DOPA can cause prominent side effects that counteract its effectiveness.
