This video illustrates how estrogen is extracted from a drop of human blood using a novel microfluidics chip developed at the University of Torotono. The samples are lysed, and then the estrogen is extracted into a polar solvent (methanol), while the unwanted parts of the blood sample are extracted into a non-polar solvent (isooctane).
This three-dimensional micrograph shows a living cell (shown in green) with engineered capsules (shown in red) inside. An electric shock was applied to the cell to get the capsules inside. While that approach works well in vitro, the researchers hope to come up with a more acceptable approach for clinical applications.
Dalton, a squirrel monkey who used to be red-green colorblind, can now see those colors, thanks to a novel gene therapy treatment. Scientists test his color vision by showing him a circle of red dots within a grey-green background. When Dalton touches the correct location of the red spot, he is rewarded with a drop of juice.
A tiny gripper that responds to chemical triggers could be a new tool for surgery.
This video shows how researchers at Oregon Health & Science University created a fertile egg through a process they call spindle-chromosomal complex transfer, which allowed for the complete replacement of mitochondrial DNA.
Surgical resident and bioengineer Bilal Shafi talks about heart failure and demonstrates how his new technology prevents it.
Konrad Hochedlinger describes the benefits of induced pluripotent stem cells and explains how he has improved their production.
Nicholas Fang explains how superlenses can enable scientists to use standard microscopes to view individual molecules inside living cells.
A video narrated by Russell Stewart shows the sandcastle worm creating its mineral tube and a brief demonstration of synthetic adhesive based on the worm's natural glue.
Amputee athletes are getting faster and stronger.
