This movie shows high speed imaging of HIV transfer across a virological synapse. The video begins with a still view of two T cells with transmitted light and an outline of a spot where a synaptic button has formed between them. The movie then shows the movement of fluorescent viral protein into the synaptic button, followed by transfer of material from the button into the target cells. Note the movie focuses on the movement of the viral protein without indicating the outlines of the recipient cell.
The Model S, the company’s second vehicle, has been unveiled.
The video shows a cell that has engaged in a synapse becoming infected days later. Infection was captured by continuous long term imaging over 3 days. The HIV green fluorescence image is presented on the left while an overlay of green fluorescence and bright field image is shown on the right. Images were acquired every 10 minutes over 67 hours.
A treatment helps restore muscle function to dogs with a form of muscular dystrophy.
A two-millimeter-wide strip of an airy carbon-nanotube material expands to more than three times its width when a five-kilovolt voltage is applied to it.
Hothead Technologies has developed a system that can sense and warn a user of heatstroke. In this video, an RFID transmitter is fitted in a headband and a white temperature-sensing patch touches the wearer's forehead. Readings are beamed to a PDA (not shown). When the wearer's temperature hits 102.5 and stays there for 20 seconds, an alarm sounds on the PDA.
