Comprehensive Cow Milk Metabolite Database Now Online

Comprehensive Cow Milk Metabolite Database Now Online

    Some recipes are meant to be top secret—Colonel Sanders’ fried chicken; Big Mac’s special sauce; your great aunt Ingrid’s sherry cake. But the ingredients in cow milk shouldn’t be private and confidential. The advent of targeted metabolomics approaches, which characterize large numbers of small molecules in milk, offers the opportunity to produce a detailed and comprehensive picture of cow milk’s chemical composition. And yet, many studies employing these new techniques have not publicly reported their findings, or report the components they have found but not their concentrations. Rather than having scientists continuing to re-invent the analytical milk wheel, a team of Canadian researchers has just published a “centralized, comprehensive, and electronically accessible database” of all detectable metabolites in cow milk. We may never know what Colonel Sanders uses to season his fried chicken batter, but the (detectable) chemicals that make up cow milk—all 2,355 of them—are now on the record. Read More...

The Dynamic Human Milk Proteome

The Dynamic Human Milk Proteome

Babies change a great deal in six months. Beyond the obvious that they grow bigger, considerable development occurs in all aspects of the infant’s physiology and anatomy, especially the brain, gastrointestinal tract, and immune system. New technologies have enabled scientists to discover which proteins are in milk and how they change over time to support this unique developmental period. Read More...

Milk Banks Around the World

Milk Banks Around the World

As the benefits of breast milk have become better known and the world has become more connected, sharing or selling it has concomitantly become much more common. Milk banks are the most institutionalized method of milk sharing, and probably the safest, but different countries run them very differently. Read More...

Making Sense of Dairy Biosystems

Making Sense of Dairy Biosystems

We live in an information-rich world. Each of us is capable of downloading gigabytes of data on our mobile or desktop devices each day. The upswing in data generation is also true of dairy science, which has moved into the big data realm. My students can create more data in an afternoon than I created in an entire PhD project when I was a student. Needless to say, capturing and analyzing this data is both challenging and rewarding. Since genomic data became more accessible, a number of approaches have been developed to bring the data together in useful ways. Gradually these approaches have become more sophisticated and insightful. A recent study by Widmann et al. provides a great example of how integrating different sources of large-scale genomic data can shed light on how dairy cows convert their feed into milk. Read More...
