Site selection for manned Mars landings: A geological perspective [PDF]

Issues relating to the selection of initial landing sites for manned Mars missions are discussed from a geological viewpoint. The two prime objectives for initial manned exploration should be the youngest unambiguous lava flows (to tie down the late end ...

Climate Risk and Tax Avoidance of Climate‐Sensitive Firms

Business Strategy and the Environment, EarlyView.
ABSTRACT This paper studies corporate tax behavior under increasing risks related to climate change. Using observations for China's listed firms in climate‐sensitive sectors from 2000 to 2020, our results highlight that tax avoidance has been employed to hedge climate change risks for climate‐sensitive firms, whereas we do not find climate risk‐induced

Entry, Descent, and Landing Performance for a Mid-Lift-to-Drag Ratio Vehicle at Mars [PDF]

In an effort to mature the design of the Mid-Lift-to-Drag ratio Rigid Vehicle (MRV) candidate of the NASA Evolvable Mars Campaign (EMC) architecture study, end-to-end six-degree-of-freedom (6DOF) simulations are needed to ensure a successful entry ...

In Vivo Biosynthesis and Direct Incorporation of Non‐Canonical Amino Acids into Proteins

ChemBioChem, Accepted Article.
Autonomous cells are engineered biological systems capable of biosynthesising and directly incorporating non‐canonical amino acids (ncAAs) into proteins. These systems have the potential to extend the applicability of the genetic code to enable large‐scale fermentative production of proteins carrying ncAAs.

Nuclear Entanglement: New Insights Into the Role of Cytoskeleton and Nucleoskeleton in Plant Nuclear Function

Cytoskeleton, EarlyView.
ABSTRACT Of the three types of cytoskeleton known in animals—actin, microtubules, and intermediate filaments—only actin and microtubules exist in plants. Both play important roles in cellular shaping, organelle movement, organization of the endomembrane system, and cell signaling.
