Structural basis of secreted acid phosphatase polymerization in the Leishmania parasite
Protein Science, Volume 35, Issue 5, May 2026.Abstract Enzymes that assemble into filaments typically transition between protomeric and polymeric states in response to cellular conditions. In contrast, the secreted acid phosphatase (SAP) of Leishmania, one of the most abundant extracellular glycoproteins produced by the parasite and regarded as a major virulence factor in the neglected tropical ...

Controlled Formation of Carbon Nanotubes and Nanotube Junctions from Bilayer Graphene
Small, Volume 22, Issue 26, 8 May 2026.Twisted bilayer graphene is cut using a scanning transmission electron microscope to create individual chiral carbon nanotubes and interconnected nanotube junctions. The sculpting is facilitated by in situ heating and automated beam control. Bilayer graphene ribbons with a width of less than approximately 4 nm spontaneously convert to CNTs, while no ...

A cryo‐EM processing pipeline for microtubules using CryoSPARC
Acta Crystallographica Section D, Volume 82, Issue 5, Page 411-420, May 2026.Cryo‐EM reconstructions of microtubules are currently technically challenging and time‐consuming for average users. A cryo‐EM processing pipeline for microtubules using CryoSPARC has been developed that overcomes many of these current issues.Microtubules are cytoskeletal filaments that are typically characterized by a discontinuous helical lattice of α/

Archives of impact: The politics of craters on Earth
Geographical Research, Volume 64, Issue 2, May 2026.This paper examines Earth’s 195 confirmed impact craters as archives, exploring their cataloguing and presentation as heritage sites. It argues Western scientific framings using military language and emphasising catastrophe overlook settler colonialism’s violent histories and marginalise indigenous earth‐sky cosmologies.

Resilience to Cardiac Aging in Greenland Shark Somniosus microcephalus
Aging Cell, Volume 25, Issue 5, May 2026.Greenland shark Somniosus microcephalus shows severe cardiac aging such as fibrosis, lipofuscin buildup, mitochondrial damage, and oxidative stress, unseen in comparison species Etmopterus spinax and Nothobranchius furzeri, yet remain healthy. S. microcephalus resilience suggests unique mechanisms that preserve heart function for centuries, offering ...
