Fossil Data Plugs Gaps In Current Knowledge, Study Shows:
Researchers have shown for the first time that fossils can be used as effectively as living species in understanding the complex branching in the evolutionary tree of life.
Cilia: Small Organelles, Big Decisions:
Johns Hopkins researchers say they have figured out how human and all animal cells tune in to a key signal, one that literally transmits the instructions that shape their final bodies. It turns out the cells assemble their own little radio antenna on their surfaces to help them relay the proper signal to the developmental proteins "listening" on the inside of the cell.
Avoiding Sweets May Spell A Longer Life, Study In Worms Suggests:
A new study in Cell Metabolism reveals that worms live to an older age when they are unable to process the simple sugar glucose. Glucose is a primary source of energy for the body and can be found in all major dietary carbohydrates as a component of starches and other forms of sugar, including sucrose (table sugar) and lactose.
