Ebullition Regulated by Pressure Variations in a Boreal Pit Lake
Frontiers in Earth Science, 2022 Methane ebullition from lakes is an important contributor to atmospheric greenhouse gases. However, ebullition is typically sampled at intervals greater than the duration of ebullition events, limiting our understanding of the factors controlling this ...

Geomagnetic Polarity Timescale [PDF]
, 2001 Dating and time control are essential geoscience, because they allow us to rock sequences from different environments of deposition. Most importantly, accurate time control allows us to calculate rates of change, which is necessary for understanding underlying processes and mechanisms.

Cryptic geological histories accessed through entombed and matrix geochronometers in dykes
Communications Earth & EnvironmentDeep geology of ancient continental crust can be difficult to access, with direct observation restricted to limited exposures. The age and composition of hidden geology can be gleaned from indirect isotopic modelling or via detrital minerals within ...

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 ...

An exogenic to endogenic thermal transition on Earth 3.9 billion years ago
Communications Earth & EnvironmentOn Earth, the primary driver of crustal magmatism is generally viewed as endogenic, a manifestation of loss of primordial and radiogenic heat from the interior.

Some Fractional Dynamic Inequalities of Hardy’s Type via Conformable Calculus
Mathematics, 2020 In this article, we prove some new fractional dynamic inequalities on time scales via conformable calculus. By using chain rule and Hölder’s inequality on timescales we establish the main results.

On the timescale forcing in astrobiology
Serbian Astronomical Journal, 2007 We investigate the effects of correlated global regulation mechanisms, especially Galactic gamma-ray bursts (GRBs), on the temporal distribution of hypothetical inhabited planets, using simple Monte Carlo numerical experiments. Starting with recently obtained models of planetary ages in the Galactic Habitable Zone (GHZ), we obtain that the times ...

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 ...
