Protrusion and retraction of lamellipodia are common features of eukaryotic cell motility . As a cell migrates through its extracellular matrix ( ECM ) , lamellipod growth increases cell-ECM contact area and enhances engagement of integrin receptors , locally amplifying ECM input to internal signaling cascades . In con... | Cells crawling through tissues migrate inside a complex fibrous environment called the extracellular matrix ( ECM ) , which provides signals regulating motility .

Be... | Next-generation sequencing has greatly expanded our ability to identify missing heritability due to rare variants . In order to increase the power to detect associations , one desirable study design is to combine samples from multiple cohorts for mapping commonly measured traits . However , many current studies sequenc... | [

Temporal analysis of sound is fundamental to auditory processing throughout the animal kingdom . Echolocating bats are powerful models for investigating the underlying mechanisms of auditory temporal processing , as they show microsecond precision in discriminating the timing of acoustic events . However , the neural b... | We routinely rely on a stopwatch to precisely measure the time it takes for an athlete to reach the finish line . Without the assistance of such a timing device , our measurement of elapsed time becomes imprecise .

Many bacteria build biofilm matrices using a conserved exopolysaccharide named PGA or PNAG ( poly-β-1 , 6-N-acetyl-D-glucosamine ) . Interestingly , while E . coli and other members of the family Enterobacteriaceae encode the pgaABCD operon responsible for PGA synthesis , Salmonella lacks it . The evolutionary force dr... | During bacterial evolution , specific traits that optimize the organism’s fitness are selected .

A main determinant of prolonged Trypanosoma brucei infection and transmission and success of the parasite is the interplay between host acquired immunity and antigenic variation of the parasite variant surface glycoprotein ( VSG ) coat . About 0 . 1% of trypanosome divisions produce a switch to a different VSG through ... | Trypanosoma brucei—a deadly parasite of humans and animals—owes its success to its ability to cope with host immunity , and the mechanism it uses to do so is a remarkable example of biological variation .
