摘要:Patients with devastating illnesses demonstrate incredible courage in battling their disease. Innovative cell and gene therapies (CGTs), built on decades of research, are changing the lives of those who suffer from conditions ranging from cancer to sickle cell disease to neurologic diseases. Although hailed for their promise and recognized for benefits that will exceed the costs, the high prices of CGTs ($300 thousand to $4 million per dose) leave these therapies out of reach for many. This ac...

摘要:Our hearts race with emotion as we are enthralled by the mesmerizing love story in the movie Titanic. Our hunger stirs to life as we are enchanted by the tantalizing cuisine showcased in Ratatouille. Our breath hangs in suspense as we are electrified by the adrenaline- pumping moments in Mission Impossible. Both external and internal experiences shape the very essence of our lives.

摘要:The RNA-guided ribonuclease CRISPR-Cas13 enables adaptive immunity in bacteria and programmable RNA manipulation in heterologous systems. Cas13s share limited sequence similarity, hindering discovery of related or ancestral systems. To address this, we developed an automated structural-search pipeline to identify an ancestral clade of Cas13 (Cas13an) and further trace Cas13 origins to defense-associated ribonucleases. Despite being one-third the size of other Cas13s, Cas13an mediates robust pr...

摘要:Despite extensive investigation, the nature and causes of the Mid-Pleistocene Transition remain enigmatic. In this work, we assess its linkage to asynchronous development of bipolar ice sheets by synthesizing Pleistocene mid- to high-latitude proxy records linked to hemispheric ice sheet evolution. Our results indicate substantial growth of the Antarctic Ice Sheets (AISs) at 2.0 to 1.25 million years ago, preceding the rapid expansion of Northern Hemisphere Ice Sheets after similar to 1.25 mil...

摘要:Incorporation of polymer chain entanglements within a single network can synergistically improve stiffness and toughness, yet attaining such dense entanglements through vat photopolymerization additive manufacturing [e.g., digital light processing (DLP)] remains elusive. We report a facile strategy that combines light and dark polymerization to allow constituent polymer chains to densely entangle as they form within printed structures. This generalizable approach reaches high monomer conversio...

摘要:An ever-present limitation of transmission electron microscopy is the damage caused by high-energy electrons interacting with any sample. By reconsidering the fundamentals of imaging, we demonstrate an event-responsive approach to electron microscopy that delivers more information about the sample for a given beam current. Measuring the time to achieve an electron count threshold rather than waiting a predefined constant time improves the information obtained per electron. The microscope was m...
