The Rich Chemistry of Ionized Methanol With Sulfur Dioxide: Pathways to Prebiotic and Elusive Species in Earth's Atmosphere and Space

open access: yesChemistry – A European Journal, EarlyView.
The reaction between the methanol radical cation and sulfur dioxide is remarkably fast and forms several ionic and neutral products (HOSOH+, CH2OSO+, CH2OH+, CH2O, H2O, HSO2). The chemistry goes beyond simple proton or hydrogen transfer, revealing a close interaction between the two species, relevant to atmospheric and astrochemical environments where ...

Reversible Cystine Disulfide Scaffolding Enables Carbonyl Sulfide‐Mediated Intramolecular Peptide Bond Formation via Cyclocystine: Implications for Prebiotic Chemistry

open access: yesChemistry – A European Journal, EarlyView.
Cystine is unique among amino acids, in that the disulfide bond can allow intramolecular peptide bond formation. This cyclization offers potential advantages for intramolecular coupling selectivity in prebiotic peptide formation. ABSTRACT Treatment of cystine (the disulfide‐linked dimer of cysteine) with carbonyl sulfide (COS) results in the formation ...

Omori‐like decay of postseismic velocities following continental earthquakes

open access: yesGeophysical Research Letters, 2017
Various mechanisms have been proposed to explain the transient, enhanced surface deformation rates following earthquakes. Unfortunately, these different mechanisms can produce very similar surface deformation patterns leading to difficulty in ...

Investigating the Cytoskeleton of DRGs Using Cryo‐Electron Microscopy and Deep Learning

open access: yesCytoskeleton, EarlyView.
ABSTRACT We describe a method for determining the ultrastructural organization of axons and varicosities of cultured dorsal root ganglion (DRG) neurons using cryogenic electron microscopy (cryo‐EM). Cryo‐EM reveals the dimensions, proximity, and overall organization of biological specimens in a near‐native state, avoiding artifacts of fixation and ...

The pristine interior of comet 67P revealed by the combined Aswan outburst and cliff collapse

open access: yesNature Astronomy, 2017
Outbursts occur commonly on comets1 with different frequencies and scales2,3. Despite multiple observations suggesting various triggering processes4,5, the driving mechanism of such outbursts is still poorly understood.

Comet Lesions in Patients with Pseudoxanthoma Elasticum

open access: yes, 2015
Pseudoxanthoma elasticum (PXE) is a genetic multisystemic disorder affecting the skin, eyes and cardiovascular system. Basic fundoscopic findings in PXE result from Bruch’s membrane involvement.

Visualizing Specific Tubulin Isotypes and Pathogenic Variants in Cellular Microtubule Arrays

open access: yesCytoskeleton, EarlyView.
ABSTRACT Eukaryotic cells depend on dynamic microtubule arrays to execute a wide range of functions vital for life. These microtubule filaments are formed through the polymerization of α/β‐tubulin proteins, which can be generated from numerous tubulin genes, or isotypes.

Toward Fit‐for‐Purpose Data for Drug Assessment in Non‐small Cell Lung Cancer: A Core Dataset

open access: yesClinical Pharmacology &Therapeutics, EarlyView.
Considering the high unmet medical need in people with non‐small cell lung cancer (NSCLC), the drug assessment for targeted therapies often rely on small populations and single‐arm trials, challenging the evaluation by regulatory authorities, health technology assessment bodies (HTAb), and clinicians.
