The Star Formation Law in Nearby Galaxies on Sub-Kpc Scales
, 2008 (Abridged) We present a comprehensive analysis of the relationship between star formation rate surface density (SFR SD) and gas surface density (gas SD) at sub-kpc resolution in a sample of 18 nearby galaxies.

DESI EDR: Calibrating the Tully–Fisher Relationship with the DESI Peculiar Velocity Survey
The Astrophysical JournalWe calibrate the Tully–Fisher relation (TFR) with data from the DESI Peculiar Velocity (PV) Survey taken during the Survey Validation (SV) period of the DESI galaxy redshift survey.

The FEBS Journal, Volume 293, Issue 8, Page 2270-2290, April 2026.Antifreeze proteins from winter‐active spiders were purified using their affinity for ice. After LC–MSMS characterization, corresponding transcripts were identified. The antifreeze protein folds as a β‐solenoid with a large flat ice‐binding site on one surface and can bind to ice crystals and prevent their growth at −4 °C.

Modified Newtonian Dynamics: A Falsification of Cold Dark Matter
Advances in Astronomy, 2009 The only viable alternative to dark matter is one in which Newtonian dynamics or gravity breaks down in the limit of low accelerations, as in modified Newtonian dynamics (MONDs).

Automated Quantitative Description of Spiral Galaxy Arm-Segment Structure [PDF]
, 2013 We describe a system for the automatic quantification of structure in spiral galaxies. This enables translation of sky survey images into data needed to help address fundamental astrophysical questions such as the origin of spiral structure---a ...

Immunology, Volume 177, Issue 4, Page 736-748, April 2026.A constant rate of DNA damage that is not perfectly repaired will cause a constant rate of DNA mutations. The chance of mutation will increase if DNA is prone to damage, such as occurs in somatic hypermutation (SHM) hotspots and GC‐rich DNA. Thus, if one mutation‐prone DNA site drives disease, the age of onset of disease and degree of penetrance should

Magnetic-Field Vector Maps of Nearby Spiral Galaxies
Galaxies, 2019 We present a method for determining the directions of magnetic-field vectors in a spiral galaxy using two synchrotron polarization maps, an optical image, and a velocity field.

New Phytologist, Volume 250, Issue 2, Page 970-987, April 2026.Summary Flowering of perennial Arabis alpina is differentially regulated on primary and axillary shoots. Although contributions of vernalization and ageing pathways have been analysed, those of photoperiodic flowering genes CONSTANS (CO), FLOWERING LOCUS T (FT), and TWIN‐SISTER OF FT (TSF) remain unexplored.
