In this video, the researchers demonstrate a few applications that could be incorporated with their pressure-sensitive touch pad, dubbed the UnMousePad. The researchers connect the pad to a computer and display to create a map of the intensity and location of pressure points. The pad can also be used to draw with fingers, write with a stylus, sculpt virtual globes, and control electronic musical equipment.
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.
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.
A rotating three-dimensional view of an HIV infected T cell (green) forming virological synapses with three healthy CD4+ cells (red). The viral structural protein, shown in green, accumulates in button-shaped structures at the contact sites.
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.
A treatment helps restore muscle function to dogs with a form of muscular dystrophy.
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.
Scott Laughlin, CEO of Zymetis, discusses his company’s work to genetically modify bacteria that efficiently converts biomass to sugar.
Experts on a panel called “Basketball Analytics” at MIT Sloan School of Management’s Sports Analytics Conference 2009 discussed ways to quantify sports.
The New York startup, Sense Networks, has developed algorithms that can identify distinct types of behaviors of people in a city, and group them into so-called tribes. The first animation shows the changing whereabouts of these tribes over the course of an evening in San Francisco and the second animation depicts the process of identifying the primary tribes visiting the top 200 nightlife destinations during a certain period of the night.
