Do cells in the blood, heart and lungs smell the food we eat?
In a discovery suggesting that odors may have a far more important role in life than previously believed, scientists have found that heart, blood, lung and other cells in the body have the same receptors for sensing odors that exist in the nose.

First tests of old patent medicine remedies from a museum collection

Final chapter to 60-year-old blood group mystery
Researchers have solved a 60-year-old mystery by identifying a gene that can cause rejection, kidney failure and even death in some blood transfusion patients.

Engineering algae to make the 'wonder material' nanocellulose for biofuels and more
Genes from the family of bacteria that produce vinegar, Kombucha tea and nata de coco have become stars in a project -- which scientists today said has reached an advanced stage -- that would turn algae into solar-powered factories for producing the
