    A matter of fine balance: electrical balance in the brain

    Image: Despite more than a million fold difference in the light intensity, our brains enable us to see the same scene in broad daylight and a dim night by the process of normalization. This article shows how brains "can" perform normalization by precisely balancing two equal and opposite forces - excitation and inhibition.

    A molecular rheostat for insulin signalling

    A mutant fruitfly strain studied by researchers from the National Centre for Biological Sciences (NCBS), Bangalore, may hold the key to understanding what goes wrong with insulin signalling in type-2 diabetes. When raised on a high-sugar diet, normal flies show a 25% increase in blood sugar levels; but the mutant flies—which lack the enzyme PIP4K (short for phosphatidylinositol 5 phosphate 4-kinase)— have normal blood sugar levels when raised on a high-sugar diet.

    Genomics uncovers the mystery of the magic drumstick tree - Moringa oleifera

    Did you ever wonder why our grandmothers insisted on having a Tulsi plant (Holy Basil) in front of the house and a Moringa (Drumstick) tree in the backyard? Each and every part of the drumstick tree has a medicinal value and is a rich source of nutrients and minerals.
