Circular chemistry: Adapting linear chemistry to mitigate the climate crisis
Mètode Science Studies Journal: Annual ReviewIn this article we explore the imperative shift from a linear economic model to a circular one, with a particular focus on the pivotal role of chemistry in this transition. It elucidates the critical global challenges stemming from unsustainable resource

Insights into a long life without cancer: The case of the bowhead whale
Molecular Oncology, EarlyView.Long‐lived, large‐bodied organisms have evolved powerful anticancer mechanisms that preserve cellular and tissue integrity across extended lifespans. A recent study by Firsanov et al. shows that greater genome stability is a key factor underlying the remarkable longevity and cancer resistance of one such species, the bowhead whale.

Dynamics of Planetesimals due to Gas Drag from an Eccentric Precessing Disk
, 2010 We analyze the dynamics of individual kilometer-size planetesimals in circumstellar orbits of a tight binary system. We include both the gravitational perturbations of the secondary star and a non-linear gas drag stemming from an eccentric gas disk with ...

On the restricted circular three-charged-body problem
Astrophysics and Space Science, 1987 Three bodies \(M_ 1\), \(M_ 2\) and M with masses \(m_ 1\), \(m_ 2\) and \(m=0\), and charges \(q_ 1\), \(q_ 2\), \(q=0\) revolve around the centre of mass of the first two in circular orbits attracting (or repulsing) each other according to the Newtonian and Coulombian inverse square law.

Molecular cancer prevention: Intercepting disease
Molecular Oncology, EarlyView.Oncological practice must evolve, from treating established tumours to proactive cancer interception before clinical manifestation. This will require mechanistic insight into tumour initiation, validated biomarkers of early disease development and redesigned clinical trials, enabling cancer interception to become a core pillar of oncology with the ...
