Unraveling the active site cover of coproheme decarboxylase from Listeria monocytogenes

The FEBS Journal, EarlyView.
During heme biosynthesis in Gram‐positive bacteria, coproheme decarboxylase (ChdC) catalyzes the conversion of four‐propionate substrate coproheme to the two propionate product heme b. Its active site is universally covered by a flexible linking loop. This study identifies an important histidine residue, which stabilizes the loop in a ChdC homolog.

Natural disaster risk salience and the strategic appointment of directors with sustainability expertise

Journal of Financial Research, EarlyView.
Abstract This article examines how salient sustainability risks from near‐miss natural disasters influence board composition. Using a difference‐in‐differences design, I find that firms located in counties neighboring disaster‐affected areas significantly increase the presence of directors with sustainability expertise following the disaster.

Axial muscle‐fibre orientations in larval zebrafish

Journal of Anatomy, Volume 246, Issue 4, Page 517-533, April 2025.
In 4 days post‐fertilization zebrafish larvae, the fast axial muscle fibres follow helical trajectories that taper towards the tail. Adjacent muscle fibres form substantial angles relative to each other to accommodate this pattern. Using a novel semi‐automatic method, we quantified 3D fibre angles over the whole muscle volume.

Generics favor stability

Mind &Language, EarlyView.
Humans seek to predict, explain, and control their environments. Generalizations—like those expressed by “children like candy” and “cigarettes cause cancer”—provide one resource to facilitate these tasks. We develop a proposal tying the acceptability judgments of generics to the psychological functions of generalizations.

Laws and Reasons Why

Analytic Philosophy, EarlyView.
ABSTRACT Laws play some role in explanations: at the very least, they somehow connect what is explained, or the explanandum, to what explains, or the explanans. Thus, thermodynamical laws connect the match's being struck and its lightning, so that the former causes the latter; and laws about set formation connect Socrates' existence with {Socrates}'s ...

Disasters, Dictators, and Donors: The Impact of Foreign Aid on Economic Activity (Mis)Reporting

Review of Development Economics, EarlyView.
ABSTRACT This paper examines how governments manipulate economic data to secure more foreign disaster aid. By using nighttime lighting as a reliable measure of economic activity, we make two key findings: (1) foreign disaster aid is positively linked to a country's understatement of its gross domestic product, indicating a deliberate strategy to ...
