Researchers have contributed significant new evidence to support the idea that high doses of cocaine kill brain cells by triggering overactive autophagy (normal physiological process in the body that deals with destruction of cells), while working with mice.
Scientists have identified a fat molecule in brain cells that may act as a 'switch' to increase or decrease the motivation to consume nicotine, a finding that could lead to new therapies to help smokers kick the butt.
Glutathione deficiencies produce redox changes in brain cells. Redox reactions involve the transfer of electrons, which leads to alterations in the oxidation state of atoms and may affect brain metabolism and inflammation.
In a first, an Indian American researcher from Salk Institute for Biological Studies in California has developed a new way to selectively activate brain, heart, muscle and other cells using ultrasonic sound waves.
New research suggests that a particular class of pesticides called "neonicotinoids" do not kill bees but impair their brain function to disturb learning, blunt food gathering skills and harm reproduction.
In a ray of hope for people suffering from dementia, researchers -- led by one of Indian origin -- have found that stimulating the brain though minute amounts of electricity enhances the growth of new brain cells and improves short and long-term memory.
