Macrophages in the tumor microenvironment have been suggested to play a key role in driving tumor progression, but the underlying mechanism remains unclear. Here, we show in Drosophila imaginal discs that the phagocytic activity of mature p...

Retinitis pigmentosa (RP) is a constellation of genetically inherited diseases, most often caused initially by mutation of a rod photoreceptor gene and leading eventually to blindness.1 Although the ultimate prognosis for RP is grim, many f...
Mechanical cues polarize ADIP protein complexes to control vertebrate morphogenesis and wound healing [0.03%]

Planar cell polarity (PCP) is a phenomenon of coordinated cell orientation in many epithelia and is required for early morphogenetic events, such as vertebrate gastrulation or neural tube closure, that place embryonic tissues in their prope...

The invasion of specialized ecological niches can cause drastic changes to selection regimes, resulting in genomic and phenotypic transformation.1 High-altitude habitats offer an excellent opportunity to investigate the genetic basis of loc...

The single-celled ciliate Stentor coeruleus demonstrates habituation to mechanical stimuli, but the mechanism of learning in this single cell, which lacks a nervous system, is currently not known. Here, we propose a simple biochemistry-base...

A major challenge in biology is comprehending how complex multicellular novelties evolve. Central to this problem is explaining how qualitatively new phenotypic traits - typically the focus of comparative developmental and macroevolutionary...
Ecology: Genomic erosion of mountain grassland plants in greener pastures [0.03%]

Mountain grasslands are home to important plant species but are threatened by land-use and climate change. A new study integrates satellite and genomic data, revealing how increased vegetation productivity threatens diversity in a grassland...

How marine species cope with both diurnal and tidal cycles is unclear. A new study in crustaceans identifies distinct brain cells that exhibit either 24- or 12.4-hour rhythms of gene expression, thus providing a mechanism for tracking multi...

Homeostatic control of neural networks is based on monitoring the activity level of neurons and adjusting excitability. A recent study demonstrates that the physical environment per se (temperature) can directly regulate the neural circuits...

Apparently for their own enjoyment, young white-faced capuchin monkeys abducted dependent infant howler monkeys and kept them for days. This new tradition is the first identified in primates incorporating forcible abduction of another speci...
