Scientists have discovered how a family of proteins regulates an important cellular cycle where a cell's generated energy is converted to necessary functions, a finding with potential to lead to significant breakthroughs in treatment of Parkinson's, chronic liver and heart diseases.


New insights in cellular pump dynamics


Pregnant women are particularly vulnerable to depression, but women who take anti-depressants during pregnancy may be predisposing their infants to Type 2 diabetes and obesity later in life, says a study.


Anti-depressants during pregnancy up obesity, diabetes risk in kids


Biologists have found the "missing link" in the chemical system that enables animal cells to produce ribosomes - the thousands of protein factories in each cell that manufacture all of the proteins needed to build tissue and sustain life.


'Missing link' in ribosome production holds key for cancer cure


Staying in a cool environment may help you stay fit as researchers have discovered that such environment stimulates growth of brown fat that burns energy to generate heat and may protect people from diabetes and obesity.
