Continuous Metabolic Phenotyping – How Continuous is “Continuous”?

A continuous metabolic phenotyping system is required for tracking rapid changes in metabolic data. Such a metabolic phenotyping system must sample continuously from each cage in parallel. Because each cage gets its own gas analyzer [...]

Sex, lies, and water vapor

OK, don’t get your hopes up. This will be the last mention of sex in this blog entry. However, we will deal at length with lies and water vapor, especially lies (OK, OK, let's just [...]

Tiny Food Intake Events (Micro-Intakes) Can be Important!

Many food intake events (= food uptake events) are too small for legacy "food intake measurement systems" or metabolic phenotyping systems to detect. Each of these feeding events corresponds to a neurological signal to feed, [...]

Combining a metabolic cage (with urine and feces collection) and respirometry: It’s easy!

In some fields of research, a difficult balancing act exists between answering different questions. For example, a researcher may need to measure metabolic rates, while also needing quantitative measurements of urine and feces output.  Measuring [...]

Distinguishing individual food uptake in communally housed mice using RFID

Mice are communal beasts, just like rats. They live in groups, and separating them - as required for measuring food intake / food uptake or energy expenditure - stresses them, elevating cortisol levels and leading [...]

A solution for bulk photosynthetic efficiency screening

Sometimes strange ideas come into my head. Most of the time, being too busy to act on them, I shoo them away and get on with my life. On this one occasion, though, we had [...]

The “Deep Data Field System” in Metabolic Phenotyping

Data from a metabolic phenotyping system can be rigidly determined by the parameters entered at the time of the experiment (as with legacy systems), or the data can be a rich mine of information, with [...]

Activity Metabolism Measurements Made Easy in Metabolic Phenotyping

One of the classic controversies in the field of metabolic science is the effect of activity on overall energy expenditure. As a comparative physiologist with a long-standing interest in energetics (and several papers published in [...]
