The cytochrome oxidase defect in ISC‐depleted yeast is caused by impaired iron–sulfur cluster maturation of the mitoribosome assembly factor Rsm22

open access: yesFEBS Letters, EarlyView.
The yeast mitoribosome assembly factor Rsm22 contains a [4Fe‐4S] cluster that is matured by the mitochondrial iron–sulfur cluster assembly (ISC) machinery. Defects in ISC components result in impaired mitochondrial protein synthesis due to a mitoribosome assembly defect.

Development of visible light‐sensitive human neuropsin (OPN5) via single amino acid substitution

open access: yesFEBS Letters, EarlyView.
The present study determines a key amino acid residue, Lys91, for defining UV sensitivity of human OPN5. Heterologous action spectroscopy of the wild type and K91 mutants of OPN5 in HEK293T cells reveals that substitution of Lys91 with neutral (alanine) or acidic amino acids (glutamic or aspartic acids) causes substantial shifts in spectral sensitivity

Trees and Carbon [PDF]

open access: yes
The transport and transformation of substances in the environment are known collectively as biogeochemical cycles. These global cycles involve the circulation of elements and nutrients that sustain both the biological and physical aspects of the ...

Technology Teacher: Navigating by Good Gyrations [PDF]

open access: yes, 2002
This activity describes some simple, yet impressive gyroscopic demonstrations using only a bike wheel with a quick-release hub. Then, itIt explains both the angular momentum principle that tends to keep the wheel in a rigid plane and the effects of the ...

Exploring lipid diversity and minimalism to define membrane requirements for synthetic cells

open access: yesFEBS Letters, EarlyView.
Designing the lipid membrane of synthetic cells is a complex task, in which its various roles (among them solute transport, membrane protein support, and self‐replication) should all be integrated. In this review, we report the latest top‐down and bottom‐up advances and discuss compatibility and complexity issues of current engineering approaches ...

Technology Teacher: Listening for Rings from Space [PDF]

open access: yes, 2004
This activity introduces gravitational waves and the NASA technology being developed to detect them in space. It involves building a metaphorical interferometer that demonstrates how the mission (and all interferometry) works.
