Quantum Crystallography in Focus: Highlights from Sagamore XX-2024

Image

The Sagamore XX-2024 Conference on Quantum Crystallography, held from 10th to 15th November 2024, at the Shiv Nadar Institution of Eminence (deemed to be a University), Delhi-NCR, marked a significant milestone as the 20th iteration of this prestigious international event was convened for the first time in India. Since its inception in 1964, this meeting has brought together leading researchers in the field of quantum crystallography and related disciplines.

What We Stand to Lose: Science, Truth and the Role of Community

I open this Editorial with a personal view. We are clearly living in strange and difficult times. Apart from the obvious concerns about conflicts throughout the world, which I need not elaborate on here, as a scientist and confirmed internationalist, I worry about the growth of anti-science movements in recent years.

Cockroach milk crystals reveal an unusual solution to protein crystallization

2026 Ig Nobel Prize-winning researchers Ramaswamy Subramanian, Leonard Chavas and Nathan Coussens were among the authors of a remarkable study that revealed how naturally formed protein crystals in the viviparous cockroach Diploptera punctata challenge conventional ideas about protein crystallization.
