Spider silk is prized for its unrivaled strength and toughness. But figuring out a way to mass-produce it is no easy feat. Spiders cannot be put to work to pump out the fibers the way silkworms can: ...

Magnesium (Mg)-based materials are considered as potential materials for biodegradable vascular stents, and some Mg-based stents have obtained regulatory approval. However, the development and ...

Quantum turbulence—the stochastic motion of quantum fluids such as 4 He and 3 He-B, which display pure superfluidity at zero temperature and two-fluid behavior at finite but low temperatures—has been ...

Shown are two pathways to MH: I is the low-temperature pathway, and II is the high-temperature pathway. In pathway I, phases for pure para hydrogen have lettered names: LP, low pressure; BSP, broken ...

Taxanes form a large family of terpenes comprising over 350 members, the most famous of which is Taxol (paclitaxel), a billion-dollar anticancer drug. Here, we describe the first practical and ...

Multiple lines of evidence support the hypothesis that the early evolution of life was dominated by RNA, which can both transfer information from generation to generation through replication directed ...
