We study how desert ants, Cataglyphis niger, a species that lacks pheromone-based recruitment mechanisms, inform each other about the presence of food. Our results are based on automated tracking that allows us to collect a large database of ant trajectories and interactions. We find that interactions affect an ant's speed within the nest. Fast ants tend to slow down, whereas slow ones increase...

Development of muscle is critically dependent on several hormones which in turn are regulated by nutritional status. We therefore determined the impact of mild postnatal undernutrition on key markers of myofibre function: type I slow myosin heavy chain (MyHC) isoform, myosin ATPase, succinate dehydrogenase and alpha-glycerophosphate dehydrogenase. In situ hybridization, immunocytochemistry and ...

The potency of plant bioactives may decline drastically upon exposure to harsh external environments including gastrointestinal conditions. protective role played by liposomes contributes desirable properties increased stability, slow/controlled release, improved bioactivity, and enhanced bioavailability the encapsulated bioactives. Also, incorporation in food matrices has resulted augmented se...

Laboratory studies have demonstrated that experimental manipulations of oral processing can have a marked effect on energy intake. Here, we explored whether variations in oral processing across a range of unmodified everyday meals could affect post-meal fullness and meal size. In Study 1, female participants (N = 12) attended the laboratory over 20 lunchtime sessions to consume a 400-kcal porti...

Analogous to the recently emerging ‘slow food’movement for the protection of the right to taste (see www.slowfood.com), the concept of ‘slow fish’may be used to convey important messages for protection of fisheries and the right to fish. The slow food movement talks about striking the right balance of respect and exchange with nature and the environment, while enhancing eating pleasure. Similar...

Importation of animals or animal products cannot take place without some element of risk. Risk analysis is a blend of art and science and is a tool intended to provide decision-makers with an objective, repeatable and defensible assessment of the risks posed by a particular import proposal. Risk analysis comprises risk identification, risk assessment, risk management and risk communication. Exa...

Enduring episodic memories are thought to be formed in a dialog between hippocampus and neocortex promoting the redistribution of newly encoded memories from hippocampal to neocortical stores. In this issue of Neuron, Wierzynski et al. report that during slow wave sleep (SWS), driven by hippocampal sharp wave-ripple bursts, cells in prefrontal cortex fire consistently within 100 ms after hippoc...

Slow food movement gave rise to subsequent movements including Cittáslow and slow tourism. This emphasises a steady state mindful approach travel consumption patterns. With consideration for pressing issues like overtourism, mass tourism the onslaught of COVID-19 pandemic, it is pertinent discuss viable alternatives fast-paced life that we consider normal. One such alternative accentuates susta...

We examined age-dependent changes in neurofilament transport in motor axons of the rat sciatic nerve. SDS-PAGE and gel fluorography confirmed that the distribution of labeled neurofilament triplet protein coincides with the major slow component a (SCa) wave in these neurons. The velocity of neurofilament transport was calculated on the basis of the location of the 50th percentile Of radioactivi...

Cytoskeletal and cytosolic proteins are transported along axons in the slow components of axonal transport at average rates of about 0.002-0.1 microm/s. This movement is essential for axonal growth and survival, yet the mechanism is poorly understood. Many studies on slow axonal transport have focused on tubulin, the subunit protein of microtubules, but attempts to observe the movement of this ...
