Introduction to Biomedical Ontologies 1: What is an Ontology?

submitted by: jennifer.r.smith

While reading an article or looking at a website, have you ever seen the term “ontology” and wondered what that meant? Do you hear people talking about using ontologies and ask yourself what the hubbub is about? This video is designed to help answer those questions. Here is a beginner’s look at what an ontology is and why ontologies are an important tool in the scientist’s toolbox.

Short video with interviews discussing the process of adapting to the low oxygen content found at high altitude.

PSI-Are my soybeans wearing different genes?

submitted by: schulzbu
The video PSI – Are my soybeans wearing different genes? is inspired by the popular TV show “CSI-crime scene investigations”. Here, however, the investigators are solving cases in the field of plant science investigations (PSI). The stunning phenomenon that soybean plants can survive herbicide treatments and grow on fields without weed competition is investigated using DNA extraction, Polymerase chain reaction (PCR), gene analysis etc. Transgenes are found that make the soybean plants...

Role of the Neural Crest in Vertebrate Development and Evolution: Part 3: The Molecular Control of the Neural Crest Contribution to Craniofacial and Brain Development (36:10)

submitted by: video_collector
Further studies have shown that the NC cells which participate in facial skeletogenesis correspond to the anteriormost region of the body axis where the genes of the Hox cluster are not expressed. If the forced expression of Hoxa2, Hoxa3 and Hoxb4 (the most anteriorly expressed Hox genes) is induced in this part of the neural fold, brain development is deeply affected with anencephaly and no skeletogenesis takes place in the face which fails to develop. This phenotype is reproduced when the...

Role of the Neural Crest in Vertebrate Development and Evolution - Part 2: The Role of the Neural Crest in Head Development and in Vertebrate Evolution (30:04)

submitted by: video_collector
Nicole Le Douarin shares her research on the role of the neural crest in skeletal development. The Q/C (quail/chick) marker system revealed that apart from the peripheral nervous system (PNS), the melanocytes and some endocrine tissues, the NC plays a major role in the construction of the vertebrate head. The entire facial skeleton and part of the skull (frontal, squamosal, parietal bones) are of NC origin together with the connective tissues of the face and ventral part of the neck. The...

Metagenomic Analysis of Deep Subsurface Environments Hideto Takami, Japan Agency for Marine-Earth Science and Technology (JAMSTEC)

submitted by: dougramsey
As a deep subsurface biosphere is thought to be the biggest biosphere in the earth, it is very interesting to know the phylogenetic and functional diversity in such environments. However, there is a little biological information for them because it is very hard to recover whole microbial community by only culture-base methods. In that sense, metagenomics is one of major useful methods to elucidate the microbial flora in unknown biosphere, which seems to be constructed by mainly unculturable...
