By dawn or dusk—how circadian timing rewrites bacterial infection outcomes
FEBS Letters, EarlyView.The circadian clock shapes immune function, yet its influence on infection outcomes is only beginning to be understood. This review highlights how circadian timing alters host responses to the bacterial pathogens Salmonella enterica, Listeria monocytogenes, and Streptococcus pneumoniae revealing that the effectiveness of immune defense depends not only

Phosphatidylinositol 4‐kinase as a target of pathogens—friend or foe?
FEBS Letters, EarlyView.This graphical summary illustrates the roles of phosphatidylinositol 4‐kinases (PI4Ks). PI4Ks regulate key cellular processes and can be hijacked by pathogens, such as viruses, bacteria and parasites, to support their intracellular replication. Their dual role as essential host enzymes and pathogen cofactors makes them promising drug targets.

Technology Teacher: Navigating by Good Gyrations [PDF]
, 2002 This activity describes some simple, yet impressive gyroscopic demonstrations using only a bike wheel with a quick-release hub. Then, itIt explains both the angular momentum principle that tends to keep the wheel in a rigid plane and the effects of the ...

Five ways to model active processes in elastic solids: Active forces, active stresses, active strains, active fibers, and active metrics [PDF]
Mechanics Research Communications, 2018 An important contribution of Gerard Maugin was his study of anelasticity. It is well appreciated that in biological systems, anelasticity manifests itself through growth and remodeling and Maugin and his collaborators have helped build a general theory suitable to model such fundamental processes.

The role and implications of mammalian cellular circadian entrainment
FEBS Letters, EarlyView.At their most fundamental level, mammalian circadian rhythms occur inside every individual cell. To tell the correct time, cells must align (or ‘entrain’) their circadian rhythm to the external environment. In this review, we highlight how cells entrain to the major circadian cues of light, feeding and temperature, and the implications this has for our

The First Law of Thermodynamics (title provided or enhanced by cataloger) [PDF]
This lesson builds upon the previous one (Newton's Second Law) by introducing students to kinetic and potential energy. Topics include a brief description of these two forms of energy, a discussion of gravity as a form of potential energy, and a ...

Technology Teacher: Listening for Rings from Space [PDF]
, 2004 This activity introduces gravitational waves and the NASA technology being developed to detect them in space. It involves building a metaphorical interferometer that demonstrates how the mission (and all interferometry) works.

Molecular bases of circadian magnesium rhythms across eukaryotes
FEBS Letters, EarlyView.Circadian rhythms in intracellular [Mg2+] exist across eukaryotic kingdoms. Central roles for Mg2+ in metabolism suggest that Mg2+ rhythms could regulate daily cellular energy and metabolism. In this Perspective paper, we propose that ancestral prokaryotic transport proteins could be responsible for mediating Mg2+ rhythms and posit a feedback model ...
