Android is also getting an upgrade for Circle to Search, enabling it to search for multiple objects seen on screen at once. One implementation of this is full-outfit searches using "find the look." Once the app has found all the individual pieces of the circled outfit, users can try them on virtually. This will be available on Galaxy S26 and Pixel 10 devices. The beefed-up feature can also be used to gain insights into multiple objects in an image.
Amid such rising demand, it’s understandable that researchers worried when Morocco reduced exports of agarophytes in 2015. This shortage — due to a combination of overharvesting, climate warming, and an economic shift to internal manufacturing in the North African country — not only caused alarm but a three-fold price increase of wholesale bacteriological agar, which reached $35-45 per kilogram. (At the time of writing this in late 2025, factory agar prices are sitting at about $30 per kilogram, according to Cobos.)
Before agar, microbiologists had experimented with other foodstuffs as microbial media. They turned to substances rich in the starches, proteins, sugars, fats, and minerals that organisms need for growth, testing with broths, bread, potatoes, polenta, egg whites, coagulated blood serums, and gelatine. However, none worked particularly well: all were easily broken down by heat and microbial enzymes, and their surface, once colonized, became mushy and unsuitable for isolating microbes.
