The paper examines flight performance in swallows and martins relative to tail fork depth, finding that intermediate fork depths correlate with better flight performance, suggesting sexual selection influences tail evolution.

The paper introduces a solid-phase extraction method using metal oxide-coated silica columns to fractionate lipids into neutral, phospholipids, and other lipid classes for lipidomics.

This study investigates the evolution of leading-edge serrations in swallows, finding they are linked to sperm competition rather than foraging behavior, unlike in owls.

The study examines tail ornamentation in Pacific swallows, finding that those roosting in safer, less stressful environments have longer tail feathers, suggesting reduced ornamentation can become elaborated in benign conditions.

This study shows that porphyrin, a minority pigment, explains UV-induced feather color change in barn swallows, challenging the focus on predominant pigments like pheomelanin.

This study tests the sight-line and sexual selection hypotheses for facial color patterns in swallows using phylogenetic analysis, finding support for the sight-line hypothesis over sexual selection.

The paper examines the evolutionary relationship between forked tails and song in hirundines, finding that species with forked tails are more likely to have song.

The paper detects energy transfer from hydroxylated carotenoids to rhodopsin proton pumps in marine and freshwater bacteria.

The paper tests male mate preference in barn swallows using model presentations and finds males avoid tail-elongated female models, challenging the idea that males prefer more ornamented females.

This study shows that a ketogenic diet increases social affinity in asocial cavefish, suggesting a link between metabolic shifts and social behavior.

The paper shows that compensatory traits can produce a concave cost function for ornaments, challenging conclusions about evolutionary forces from experimental studies.

This study identifies diatom rhodopsin as a light-driven proton pump localized to plastid membranes and suggests it contributes to a CO2-concentrating mechanism in diatoms.

This study shows that ATR inhibition increases 5-FU sensitivity in cancer cells, independent of DNA repair pathways.

This study identifies IL-11 as a marker for fibroblasts involved in colorectal cancer progression, showing their role in tumor development through a feed-forward loop.

The paper identifies 27-hydroxycholesterol's role in regulating URAT1/SLC22A12 gene expression through estrogen response elements, linking cholesterol metabolism to serum uric acid levels.
