BiologyMeasured protein landscapes: 2026 study

Ferrari and colleagues profile 5,778 small domains with multiplexed HDX-MS and compare 13 domains with site-resolved HDX NMR.

Empirical finding
BiologyDiffusion-driven instability and developmental patterns

Turing proposed that reacting and diffusing morphogens can destabilize an initially homogeneous equilibrium and generate patterned states.

Model
BiologyCell traction as an inverse mechanical problem

Traction microscopy infers forces from cell-induced substrate displacements using a substrate mechanics model.

Method
BiologyPredicting functional landscapes from structures

Predicting conformational free energies, kinetics and function from sequence/static structures remains an open research challenge.

Open question
BiologyProbabilistic immune-receptor histories

IGoR infers generative V(D)J models by considering alternative gene choices, deletions and insertions for each receptor sequence.

Model
BiologyGeneration probability versus immune selection

A receptor’s abundance or generation probability is not itself its antigen affinity.

Method
BiologyCalcium signals and calibrated spike inference

Calcium fluorescence is an indirect activity proxy, and spike inference depends on indicator dynamics, noise and the trained/calibrated model.

Method
BiologyGCaMP8 inference: 2026 benchmark

Rupprecht and colleagues benchmark GCaMP8 inference against simultaneous mouse-neocortical electrophysiology.

Empirical finding
BiologyAdult fly wiring: 2024 structural evidence

FlyWire reconstructs chemical-synapse wiring in a sampled adult female Drosophila brain using electron microscopy and proofreading.

Empirical finding
BiologyMICrONS structure–function evidence

MICrONS combines visual-response calcium imaging and dense electron-microscopy reconstruction in one mouse visual-cortical volume.

Empirical finding
BiologyForward evolutionary simulation and census timing

Forward simulators encode reproduction, mutation, recombination, selection and population regulation through a specified life cycle.

Model
BiologyNiche stabilization and neutral similarity

Niche differences and near-neutral fitness similarities can act concurrently in a competition–colonization model.

Model
BiologyEvolutionary synthesis and competing emphases

The 2014 point/counterpoint compares emphasis on developmental bias, plasticity, niche construction and broader inheritance with the view that evolutionary theory already integrates such evidence.

Model
BiologyIdentifying eco-evolutionary feedbacks

Ecological change and heritable trait change can influence one another, but parallel time-series changes do not identify their causal directions.

Open question
Biology · ChemistryWater polarity and biological interactions

Water's molecular interactions help explain solvation, cohesion and thermal buffering.

Empirical finding
BiologyCell size and surface-to-volume scaling

For geometrically similar cells, volume grows faster than surface area.

Model
Biology · ChemistryOsmolarity and tonicity

Total particle concentration and lasting cell-volume effect are different properties.

Definition
BiologyChromosome sets and DNA content

DNA replication doubles DNA content without doubling chromosome-set ploidy.

Definition
BiologyOrganisms, populations, communities and ecosystems

Ecological levels describe different interacting sets and environments.

Definition
BiologyPopulation size, density and demographic balance

Total individuals and individuals per area or volume must be distinguished.

Model
BiologyMutation and selection: different roles

Mutations do not generally appear because an organism needs their future advantage.

Empirical finding
BiologyClades and rooted-tree interpretation

Shared ancestry is represented by topology, not by the left-to-right order of tips.

Method
Biology · ChemistryPlant water potential and pressure balance

Osmotic and mechanical contributions together determine passive water movement.

Model
BiologyGene, allele, genotype and phenotype

Genomic sequence variants and observable traits describe different levels of biological information.

Definition
Biology · ChemistryEnzyme substrates, active sites and induced fit

Substrate recognition and catalysis depend on a dynamic molecular environment.

Model
Biology · ChemistryMonomers, polymers and hydrolysis

Covalent subunit linkage and water-assisted cleavage explain biological polymer structure.

Definition
Biology · ChemistrySugars, glycosidic linkages and polysaccharides

Sugar connectivity distinguishes energy-storage and structural polysaccharides.

Definition
Biology · ChemistryFatty acids, storage lipids and membrane lipids

Lipids include several architectures rather than one repeating-monomer polymer class.

Definition
Biology · ChemistryAmino-acid residues and peptide linkages

The peptide backbone and variable side chains are different parts of protein structure.

Definition
Biology · ChemistryNucleotides and DNA/RNA backbone polarity

Bases carry sequence information on a chemically directional sugar–phosphate backbone.
