Cancer spread 'happens earlier'
(Aug 29, 2008)
Apparently "normal" cells may carry cancer to new sites long before
a tumour develops, lying dormant until key genes are activated,
experts say. US researchers say their findings, published in Science,
could explain why some breast cancers lead to new tumours long
after the disease is treated. Secondary, or metastatic, cancers
are responsible for the majority of deaths from the disease.

Alzheimer's drug 'halts' decline
(Aug 29, 2008)
UK scientists have developed a drug which may halt the progression
of Alzheimer's disease. Trials of the drug, known as rember, in
321 patients showed an 81% difference in rate of mental decline
compared with those not taking the treatment. The Aberdeen University
researchers said the drug targeted the build-up of a specific
protein in the brain.

Cell change 'keeps organs young'
(Aug 11, 2008)
Researchers may have found a way to halt the biological clock
which slows down our bodies over the decades. A US team thinks
it may have found the genetic levers to help boost a system vital
to cleaning up faulty proteins within our cells. The journal Nature
Medicine reported that the livers of genetically-altered older
mice worked as well as those in younger animals.

Sleeping soundly 'boosts memory'
(Jul 14, 2008)
A refreshing night's sleep may be the best way to boost memory,
a study suggests. Researchers found sleep appears to have a dramatic
impact on the way the brain functions the next day. It appears
to strengthen connections between nerve cells in the brain –
a process key to both learning and memory.

Blood pressure 'link to dementia'
(Jul 8, 2008)
Controlling blood pressure from middle-age onwards may dramatically
reduce the chances of developing dementia, researchers have said.
Two studies support a link between high blood pressure and dementia
risk - with one by an Imperial College London team suggesting
treatment could cut this. This study, by published in the Lancet
Neurology journal, found blood pressure drugs reduce dementia
by 13%.

Mediterranean diet 'cuts cancer'
(Jul 2, 2008)
Adopting just a couple of elements of the Mediterranean diet could
cut the risk of cancer by 12%, say scientists. A study of 26,000
Greek people found just using more olive oil alone cut the risk
by 9%. The diet, reports the British Journal of Cancer, also includes
higher amounts of fruits, vegetables, cereals, and less red meat.
