The Biology of Aging

Aging is not simply the accumulation of damage over time. It is a regulated biological process, driven by specific molecular mechanisms that scientists are only now beginning to understand. The discovery of these mechanisms has opened the possibility of interventions that could extend healthy human lifespan significantly.

Dark Matter's Last Stand

For four decades, dark matter has been the leading explanation for the mysterious gravitational effects observed in galaxies. But a new generation of experiments has failed to detect it, forcing physicists to confront the possibility that the universe may be stranger than we imagined.

CRISPR Beyond Medicine

CRISPR-Cas9 has transformed biology in less than a decade, enabling scientists to edit genomes with unprecedented precision. But the technology's implications extend far beyond treating genetic diseases — it is poised to transform agriculture, resurrect extinct species, and raise profound questions about the boundaries of human intervention in nature.

The Ocean's Silent Acid Bath

Since the Industrial Revolution, the world's oceans have absorbed roughly a third of all human carbon dioxide emissions. The chemical consequence — ocean acidification — is transforming marine chemistry at a rate not seen in at least 300 million years, threatening the calcified shells and skeletons that underpin entire ecosystems.
