Scientists slow aging by engineering longevity in cells

Human lifespan is related to the aging of our individual cells. Three years ago a group of University of California San Diego researchers deciphered essential mechanisms behind the aging process. After identifying two distinct ...

How does an aging-associated enzyme access our genetic material?

New research provides insight into how an enzyme that helps regulate aging and other metabolic processes accesses our genetic material to modulate gene expression within the cell. A team led by Penn State researchers have ...

The benefit of redundancy in biological systems

When viewed from an engineer's perspective, biology is often messy and imperfect. For example, redundancy is a common feature of biological systems, with the job of one biological component overlapping with that of another.

Their time to slime: who will be 'Mollusc of the Year'?

Will you choose beauty? The carnivorous Wavy Bubble Snail, perhaps, with its billowing skirts shimmering under UV light. Or will it be age? Like the venerable 500-year-old Methuselah oyster.
