Mobile_phone.png Here’s the house call of the future. A prototype cell phone that monitors HIV and malaria patients and tests water quality in undeveloped areas or disaster sites. Data is then be sent via the cell phone to a hospital for analysis and diagnosis.

The imaging platform is already here. It’s called LUCAS and has been experimentally installed in a cell phone and a webcam, each of which then takes an image of blood, saliva or other fluids using short-wavelength blue light. LUCAS can identify and count the microparticles instantly by using a decision algorithm to compare the captured images to a library of images.

The technology is the brainchild of electrical engineer Aydogan Ozcan of UCLA. His latest version, called holographic LUCAS, is described in the journal Lab On A Chip. Holographic LUCAS can identify smaller particles than before, such as E. coli. Ozcan’s next step is to build a handheld device for people in remote areas to use to monitor the spread of disease, allowing doctors to know where they’re most needed fast.

SIX TRUTHS

Reclaiming power from those who abuse it often starts with telling the truth. And in "This Is How Authoritarians Get Defeated," MoJo's Monika Bauerlein unpacks six truths to remember during the homestretch of an election where democracy, truth, and decency are on the line.

Truth #1: The chaos is the point.

Truth #2: Team Reality is bigger than it seems.

Truth #3: Facebook owns this.

Truth #4: When we go to work, we're in the fight.

Truth #5: It's about minority rule.

Truth #6: The only thing that can save us is…us.

Please take a moment to see how all these truths add up, because what happens in the weeks and months ahead will reverberate for at least a generation and we better be prepared.

And if you think journalism like Mother Jones'—that calls it like it is, that will never acquiesce to power, that looks where others don't—can help guide us through this historic, high-stakes moment, and you're able to right now, please help us reach our $350,000 goal by October 31 with a donation today. It's all hands on deck for democracy.
