Extending the Acute Skin Response Spectrum to Include the Far-UVC

N. E. Gutierrez-Bayona, C. Petersen, R. H. Hashmi, M. Buonanno, I. Shuryak, B. Ponnaiya, N. J. Kleiman, D. J. Brenner, D. Welch

This study extends the erythema action spectrum to far-UVC wavelengths using a mouse model, finding that 222 nm radiation requires a much higher dose to induce acute effects than current safety limits.

Crowdsourcing and phylogenetic modelling reveal parrot tool use is not rare

A. P. Bastos, S. Claessens, X. J. Nelson, D. Welch, Q. D. Atkinson, A. H. Taylor

The paper uses crowdsourcing and phylogenetic modeling to estimate the prevalence of tool use in parrots, finding it more common than previously thought.

Ocular and Facial Far-UVC Doses from Ceiling-Mounted 222 nm Far-UVC Fixtures

M. A. Duncan, D. Welch, I. Shuryak, D. J. Brenner

This study measures ocular and facial far-UVC exposure doses from ceiling-mounted 222 nm fixtures using a manikin, finding eye doses are 5.8% of the maximum measured dose.

No evidence of induced skin cancer or other skin abnormalities after long term (66 week) chronic exposure to 222-nm far-UVC radiatio

D. Welch, N. J. Kleiman, P. C. Arden, C. L. Kuryla, M. Buonanno, B. Ponnaiya, X. Wu, D. J. Brenner

This study shows no evidence of skin cancer or abnormalities in mice after 66 weeks of far-UVC exposure, supporting its long-term safety.

Wavelength-dependent DNA photodamage in a 3-D human skin model over the far-UVC and germicidal-UVC wavelength ranges from 215 to 255 nm

D. Welch, M. Aquino de Muro, M. Buonanno, D. J. Brenner

This study assesses wavelength-dependent DNA damage in a 3-D human skin model exposed to UVC light from 215 to 255 nm, finding no damage at 215-235 nm but significant damage at 240-255 nm.

Novel Integrative Modeling of Molecules and Morphology across Evolutionary Timescales

H. A. Ogilvie, F. K. Mendes, T. G. Vaughan, N. J. Matzke, T. Stadler, D. Welch, A. J. Drummond

This paper introduces a new evolutionary model, FBD-MSC, that integrates genealogical and fossilization processes to improve divergence time estimates in Caninae.

Accounting for errors in data improves timing in single-cell cancer evolution

K. Chen, J. C. Moravec, A. Gavryushkin, D. Welch, A. J. Drummond

This study improves timing accuracy in single-cell cancer evolution by modeling errors in single-cell DNA sequencing data using BEAST2, showing that error accounting shifts divergence times forward and reduces overestimation of phylogenetic diversity.

Far-UVC light: A new tool to control the spread of airborne-mediated microbial diseases

D. Welch, M. Buonanno, V. Grilj, I. Shuryak, C. Crickmore, A. W. Bigelow, G. Randers-Pehrson, G. W. Johnson, D. J. Brenner

The paper demonstrates that far-UVC light can effectively inactivate airborne aerosolized viruses while being safe for human skin and eyes.
