One of the more tedious parts of health science and microbiology is monitoring Petri dishes. It's time consuming. And, if you don't look at everything that's going on in the Petri dish often enough, you risk missing something really important.
Enter technology. A team at Caltech has put together a prototype "smart Petri dish" that monitors itself in real time and delivers information directly from the incubator to a scientist's computer. In a way, it's a lot like that time Cliff Huxtable took a Polaroid of the food inside the fridge, so his kids wouldn't keep standing there with the door open.
The prototype, dubbed the ePetri, was created from Lego blocks and a cell-phone image sensor, and uses light from a Google Android smart phone. A sample is placed on top of a small image-sensor chip, which uses an Android phone's LED screen as a light source.
The whole device is placed in an incubator, and the image-sensor chip connects to a laptop outside through a wire. As the image sensor snaps pictures of the cells growing in real time, the laptop stitches hundreds of images together to create a high-resolution picture of what is happening on the dish.

A better understanding how a sperm swims its way toward an egg could help inform new treatments for male infertility. Researchers from the University of York have now come up with a mathematical formula to model how large numbers of moving sperm interact with fluid they’re swimming through. From the University: By analysing the head […]
Dr Gale Ridge is a public entomologist at the Connecticut Agricultural Experiment Station, where an average of 23 people a day call, write or visit; an increasing proportion of them aren’t inquiring about actual insects, they’re suffering from delusional parasitosis, and they’re desperate and even suicidal.
Biologist Nipam Patel and his team at UC Berkeley study how butterflies develop wing shape and color by performing surgery on caterpillars, creating translucent windows in their cocoons.
Custom coffee vessels are the perfect piece of office flair, but it’s just a matter of time before your VOTE FOR PEDRO mug will start to lose its relevant wit. Why not have a new one every day, with whatever silly nonsense you want sticking off the sides? You can save big on your novelty […]
The Lightning port has thus far resisted the cruel fate that befell the headphone jack, and despite rumors that it may be disappearing come iPhone 8, for the present and foreseeable future, Lightning cables are a hot commodity for iPhone users. As such, we must make do in this strange time in which long, glorified […]
All the filters in the world won’t save your smartphone pics from a shaky hand. To really step up your mobile photography game, you’ll need some kind of mount to hold it steady. You could buy a smartphone attachment for a conventional camera tripod, but who wants to carry that kind of gear everywhere they […]
