Trilobites: Watch This Blob of Cells Become an Embryo in High-Resolution

When the video above starts, this wiggling, glowing blue blob seen under a new high-resolution microscope doesn’t look like much. But in just 26 seconds you and I can watch the blob’s tiny cells multiply, interact and organize into the first organ systems of a living mouse embryo.The hollow crater forming on the left will give rise to the mouse’s stomach, pancreas and liver. The narrow white line stretching across the center of the image is the notochord, or an early backbone. And the contracting region on the far-left side of the image is the beginning of a heartbeat.Researchers at the Howard Hughes Medical Institute’s Janelia Research…

‘Will You Be My Emergency Contact?’ Takes on a Whole New Meaning

“If we can figure out other examples like that we can design safer drugs for patients,” he said, adding that would help create specialized medications for smaller groups.What has hindered work in this area, he said, is the lack of a large data set containing multiple generations of detailed medical histories. Most heritability research, so far, has relied on studies of twins and specialized research looking at families that share a particular disease, like schizophrenia. Genetic research has also been limited regarding race.“The majority of research on disease heritability has been done in Caucasians of mostly northern European descent,” said Fernanda Polubriaginof, a graduate student in biomedical…
