Fluorescent probes allow dynamic visualization of phosphoinositides in living cells (left), whereas mass spectrometry provides high‐sensitivity, isomer‐resolved quantitation (right). Their synergistic use captures complementary aspects of lipid signaling. This review illustrates how these approaches reveal the spatiotemporal regulation and quantitative

Influence of Mortar Rheology on Aggregate Settlement [PDF]
The influence of the rheology of fresh concrete on the settlement of aggregate is examined. Fresh concrete exhibits a yield stress that, under certain conditions, prevents the settlement of coarse aggregate, although its density is larger than that of ...

Kaluza-Klein Reduction of a Quadratic Curvature Model [PDF]
Palatini variational principle is implemented on a five dimensional quadratic curvature gravity model, rendering two sets of equations which can be interpreted as the field equations and the stress-energy tensor.

Hematopoietic (stem) cells—The elixir of life?
The aging of HSCs (hematopoietic stem cells) and the blood system leads to the decline of other organs. Rejuvenating aged HSCs improves the function of the blood system, slowing the aging of the heart, kidney, brain, and liver, and the occurrence of age‐related diseases.

Chewing gum and stress reduction [PDF]
The behavioral effects of chewing gum have been studied for over 80 years and much of the research has been concerned with increases in alertness and attention. Another line of research has addressed the issue of whether chewing gum reduces stress. This topic has been studied in the laboratory, in epidemiological studies and real-life interventions.The

Phosphatidylinositol 4‐kinase as a target of pathogens—friend or foe?
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.

Sheared active fluids: thickening, thinning and vanishing viscosity [PDF]
We analyze the behavior of a suspension of active polar particles under shear. In the absence of external forces, orientationally ordered active particles are known to exhibit a transition to a state of non-uniform polarization and spontaneous flow. Such

The role and implications of mammalian cellular circadian entrainment
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

Impact of water temperature and sodium chloride (NaCl) on stress indicators of hybrid catfish (Clarias gariepinus Burchell x C. macrocephalus Gunther) [PDF]
This research was composed of 2 experiments. Short-term (1 day) and long-term (30 days) exposure were conductedin the laboratory. Each experiment had 2 temperature levels, high (Ht, 29.5 ± 0.5C) and low temperature (Lt, 19.5 ± 0.5C).Initial weight and ...
