The iconic MIT home page Spotlight features a daily-changing image and design that focuses on advances in research, technology and education taking place at the Institute. Though some Spotlights do run multiple days - for example Friday's spot usually runs through the weekend, we work very hard to maintain the daily-changing tradition. We've combed our servers and have compiled a digital archive of the Institute home page through the years - well over 2000 images. Enjoy!

Batteries for renewablesToday’s Spotlight uses a photograph, by Felice Frankel, of a physical model of the liquid metal battery.

Researchers at MIT have improved a proposed liquid battery system that could enable renewable energy sources to compete with conventional power plants.

Donald Sadoway and colleagues have already started a company to produce electrical-grid-scale liquid batteries, whose layers of molten material automatically separate due to their differing densities. But the new formula — published in the journal Nature by Sadoway, former postdocs Kangli Wang and Kai Jiang, and seven others — substitutes different metals for the molten layers used in a battery previously developed by the team.

The MIT home page Spotlight showcases the research, technology and education advances taking place at the Institute every day.

What makes it as a Spotlight image is an editorial decision by the MIT News Office based on factors that include timeliness, promotion of MIT's mission, the balance of interest to both internal and external audiences, and appropriateness.

We do welcome ideas and submissions for spotlights from community members, but please note we are not able to accommodate all requests. We are unable to run event previews or promotions as spotlights; for those looking to promote an event, we are happy to include your listing as an event headline on the homepage (when space is available).

Animal trackers

Animal trackers

Today’s Spotlight uses images, by Dr. Paddy Ryan/The National Heritage Collection, of the Otago Skink and the Jeweled Gecko in a photo‑illustration by Christine Daniloff/MIT.

Keeping track of individuals in an endangered population of animals is a cumbersome and time‑consuming task.

Conservationists physically tag animals in the wild to better follow them over time. But tagging can be intrusive for many species, and difficult to accomplish in larger populations. As an alternative, scientists have photographed animals in their natural environments and catalogued the images, along with information such as individuals’ dimensions and geographic locations.

However, as images accumulate, picking out individuals from among thousands of pictures can be a monumental task.
