A team of US nephrologists is developing first-of-its kind implantable artificial kidney with microchip filters and living kidney cells that will be powered by a patient's own heart to help kidney patients.


World's first microchip-powered device to mimic kidney functions


Setting the stage to expand the use of a patient's genetic make-up to tailor chemotherapy, an international research team has found how inherited gene variations lead to severe drug toxicity that may threaten chances for a cure in children with leukemia.


Personalised therapy for leukemia patients comes a step closer


Paving the way for new depression treatments, researchers have discovered the first-ever connection between vulnerability to depression and a type of brain cells called noradrenergic neurons.


Brain neurons linked to depression identified


The brain structures of jawless fish may not be as different from jawed vertebrates - including humans - as earlier thought, Japanese researchers have discovered.


Jawless fish brains more similar to humans than thought


A team led by an Indian-origin engineer from the University of Utah has discovered a new kind of 2D semi-conducting material for electronics that opens the door for much speedier computers and smartphones that consume a lot less power.

A new class of antigens has been identified that may be a contributing factor to type 1 diabetes. Type-1 diabetes is the auto-immune form of diabetes, in which insulin-producing beta cells in the pancreas are destroyed by body's own immune cells, a study finds.


Scientists identify antigens that may trigger type 1 diabetes


Enriching T cells -- a type of white blood cell -- to attack certain cancerous diseases may prove beneficial to an increasing number of children during immunotherapy, says a study.


Younger T cells may improve immunotherapy for cancer in kids


Long-term use of liraglutide -- a drug used to lower blood sugar levels in type 2 diabetes patients -- can have a deteriorating effect on insulin-producing cells, leading to an increase in blood sugar levels, warns a study.


Type 2 diabetes drug can weaken insulin-producing cells


Pointing to a potentially new direction for age-related cognitive care, scientists have found more evidence that ageing brains work differently than younger brains when performing the same memory task.

Asthma has been linked with a prolonged time to pregnancy and a decreased birth rate, says a study.


Asthma may delay pregnancy, decrease birth rate


Researchers, including an Indian-origin scientist, from the MIT Media Lab have developed a new imaging device that consists of a loose bundle of optical fibres with no need for lenses or a protective housing.
