Why humans evolved blue eyes

open access: yesFrontiers in Psychology
A surprising number of humans are equipped with a subpar eye model—featuring pale, colorful irides that are nowhere as good as the original dark ones at guarding the retina from sunlight and do, in fact, raise one’s risk of eye disease.

"Decoding the Narrative Mechanisms of Charles Perrault's Tale Bluebeard: A Semiotic, Semantic and Linguistic Analysis"

open access: yesZanco Journal of Humanity Sciences
Our research carries out an exhaustive study and in-depth analysis of Charles Perrault’s fairy tale Bluebeard. It aims to highlight the semiotic, semantic, and linguistic aspects of his text that structure the narrative.

Global assessment of marine plastic exposure risk for oceanic birds

open access: yesNature Communications, 2023
Plastic pollution is distributed patchily around the world’s oceans. Likewise, marine organisms that are vulnerable to plastic ingestion or entanglement have uneven distributions.

Measurements of Higgs boson properties in the diphoton decay channel with 36 fb$^{-1}$ of $pp$ collision data at $\sqrt{s} = 13$ TeV with the ATLAS detector [PDF]

open access: yes, 2018
Properties of the Higgs boson are measured in the two-photon final state using 36.1 fb$^{-1}$ of proton-proton collision data recorded at $\sqrt{s} = 13$ TeV by the ATLAS experiment at the Large Hadron Collider.

Roadmap on perovskite light-emitting diodes [PDF]

open access: yesJournal of Physics: Photonics, 2023
In recent years, the field of metal-halide perovskite emitters has rapidly emerged as a new community in solid-state lighting. Their exceptional optoelectronic properties have contributed to the rapid rise in external quantum efficiencies (EQEs) in ...

ChromEMT: Visualizing 3D chromatin structure and compaction in interphase and mitotic cells

open access: yesScience, 2017
A close-up view inside the nucleus The nuclei of human cells contain 2 meters of genomic DNA. How does it all fit? Compaction starts with the DNA wrapping around histone octamers to form nucleosomes, but it is unclear how these further compress into ...

Carrier lifetimes of >1 μs in Sn-Pb perovskites enable efficient all-perovskite tandem solar cells

open access: yesScience, 2019
Efficient all-perovskite tandem cells Organic-inorganic perovskite films can boost the output of conventional silicon solar cells in tandem geometries by utilizing more of the light at the blue end of the solar spectrum.

Electron reconstruction and identification in the ATLAS experiment using the 2015 and 2016 LHC proton-proton collision data at $\sqrt{s}$ = 13 TeV [PDF]

open access: yes, 2019
Algorithms used for the reconstruction and identification of electrons in the central region of the ATLAS detector at the Large Hadron Collider (LHC) are presented in this paper; these algorithms are used in ATLAS physics analyses that involve electrons ...
