The Speed of Light is NOT a Speed
The speed of light is a geometric conversion factor between cycle rates and linear distance traveled. It's so awesome. Enjoy. And read my choreomania paper. Also awesome.

Reconstructing enzyme evolution by protein engineering
FEBS Letters, EarlyView.Natural enzyme evolution can be retraced by protein engineering methods such as directed evolution, rational design, and ancestral sequence reconstruction. These approaches reveal how enzymes emerged from ligand‐binding scaffolds, developed varying substrate preferences, formed oligomeric complexes, adapted to environmental changes, and evolved novel ...

Relationship between Speed and Lateral Position on Curves, September 2012 [PDF]
, 2012 Excessive speed is often cited as a primary driver factor in crashes, particularly rural two-lane crashes. It has also been suggested that speed plays a significant role in crashes on curves. However, the relationship between speed and crashes on curves

Structural and synthetic studies in chemical entomology
, 1981 The alarm pheromones of the Ponerine ant Odontomachus troglodytes were found to be an homologous series of 2,6-dimethyi-a-n-aiicyiprazinesz the syntheses of these and 2,5-dimethyl-3-n-alkylprazines and 2,3-dimethyl-5-n-alkylpyrazines are described.

Effects of pretreatment methods on stability and abrasion performance of steel slag asphalt mixture
Frontiers in MaterialsSteel slag presents a promising alternative to natural aggregates in asphalt pavements; however, its high free calcium oxide (f-CaO) content leads to volume instability, which limits its large-scale application.

FEBS Letters, EarlyView.The process of internalization of the Shiga toxin A subunit via formation of a complex with the Shiga toxin B subunit, which specifically binds to the Gb3 receptor. The peptide is designed to act as a carrier of drugs into cancer cells. Here, we explored the potential of peptides derived from the catalytic A subunit of Shiga toxin (STxA) to be drug ...

Investigating transcription factor dynamics in health and disease using FRAP
FEBS Letters, EarlyView.FRAP analysis of GFP‐tagged transcription factors reveals how molecular mobility and target engagement change in response to drug treatment. By combining live‐cell imaging, quantitative model fitting, and statistical analysis, this approach uncovers transcription factor dynamics linked to disease mechanisms, providing a powerful framework for ...
