From a Pompeii-like ash burial in Morocco, a new study presents 3D trilobite fossils with a remarkably well-preserved anatomy. The results point to marine volcanic ash deposits as important sites of exceptional fossil preservation. This week in Science: https://scim.ag/7u5

About us
Founded in 1880 on $10,000 of seed money from the American inventor Thomas Edison, Science has grown to become the world's leading outlet for scientific news, commentary, and cutting-edge research, with the largest paid circulation of any peer-reviewed general-science journal. Through its print and online incarnations, Science reaches an estimated worldwide readership of more than one million. In content, too, the journal is truly international in scope; some 35 to 40 percent of the corresponding authors on its papers are based outside the United States. Its articles consistently rank among world's most cited research.

Leonard Rome’s lab discovered an odd, abundant component of cells in the 1980s—and he’s still trying to figure out what it does. Vaults, as they are called, are the most massive particles made naturally by human cells and among the most abundant. Most of our cells have roughly 10,000 of the structures, with the number rising to perhaps 100,000 in certain immune cells. Many other animals make them, too. Their abundance—and the resources cells must pour into making them—suggests vaults have some essential function. But despite decades of work by Rome and other “vaulters,” their purpose is unknown. Over the decades various hypotheses have been proposed, including that vaults help ferry things around inside cells or clear toxins. And one by one, promising ideas were dismissed or lost momentum as supporting evidence failed to materialize. Initially enthusiastic about the discovery, NIH lost interest in funding basic research on vaults as the years wore on without answers. Yet Rome’s fascination with vaults hasn’t faded, even as other researchers moved on. And now, with help from other funders and labs, he has turned from basic research on vaults to studies of how they might be exploited in medicine and other fields, as nanoscale vessels for delivering therapies and more.
