London, Mar 19 : An international team of scientists have found out why Alzheimer''s disease sufferers go on to develop epilepsy.

Led by scientists at Aberdeen University in Scotland, the research team have discovered that a protein in the brain accumulates in clumps in the brains of people suffering from dementia.

The clumps of proteins make the nerve cells too sensitive, which in turn lose their ability to communicate coherently with other nerve cells.

London, March 19: Johns Hopkins engineers say that they have developed a new lab-on-a-chip that can lead to better cancer therapies.

The researchers say that their invention may help figure out how cancer cells break free from neighbouring tissue, an "escape" that can spread the disease to other parts of the body.

London, Mar 19 : People who drink alcohol every day are at a greater risk of developing liver disease than binge drinkers, according to a study.

The study has revealed that the risk of serious liver disease is higher among those who drink heavily each day over the long term than in those who drink large amounts but then take breaks, reports the Scotsman.

The researchers found that hospital admissions for alcohol-related liver disease in the UK more than doubled between 1995 and 2005 to 13,723.

Washington, Mar 19: Having friends is not only important for the elderly’s social well being, but also for their mental and physical health, according to a study.

The research led by University of Chicago has shown that not having many close friends, and feeling of loneliness, contributes to poorer health for many older adults.

Washington, Mar 19: While tobacco has always been attributed to devastating effects on health, an international team of researchers has found a rather healthy side of tobacco plants.

The team led by Professor Mario Pezzotti at the University of Verona have genetically modified tobacco plants to produce medicines for several autoimmune and inflammatory diseases, including diabetes.

During the study, the scientists set out to create transgenic tobacco plants that would produce biologically active interleukin-10 (IL-10), a potent anti-inflammatory cytokine.
