Cellphone-based optometry solution allows for low-cost eye exams

July 5, 2010


MIT Media Lab researchers have developed an interactive, portable, and inexpensive solution for estimating refractive errors in the human eye.

The NETRA system uses an ordinary cell phone. The subject looks into this display at a very close range and aligns (overlaps) displayed patterns . Since the light rays from these patterns pass through different regions of the visual system, the alignment task gives a measure… read more

Cellphone Payments Offer Alternative to Cash

April 30, 2010

Several companies have developed small credit card scanners that plug into a cellphone and for a small fee enable any individual or small business to turn a phone into a credit card processing terminal.

Cell-transistor interface clears biolectronics hurdle

June 28, 2007

Researchers at the Max Planck Institute have developed a cell-transistor interface that they believe will usher in a new era of bioelectronics, allowing cells to be manipulated and studied without destroying them in the process.

In a demonstration, the chip was used to test the effect of new drugs on the living cells.

Cell-squirting needles could ‘weave’ new organs

October 15, 2007

A new approach to “printing” living cells could make it easier to arrange them into precise structures without harming them.

This could enable future therapies where replacement limbs or organs can be printed to order.

Cell-phone use booming in Afghanistan

August 29, 2007

About 150,000 people subscribe to cell phone service each month in Afghanistan and there’s “no end in sight” to the growth, the country’s communications minister said.

Cell-detection system promising for medical research, diagnostics

October 10, 2013

This schematic depicts a new system that uses tiny magnetic beads to quickly detect rare types of cancer cells circulating in a patient's blood, an advance that could help medical doctors diagnose cancer earlier than now possible and monitor how well a patient is responding to therapy.

Researchers are developing a system that uses tiny magnetic beads to quickly detect rare types of cancer cells circulating in a patient’s blood, an advance that could help medical doctors diagnose cancer earlier than now possible and monitor how well a patient is responding to therapy.

While other researchers have used magnetic beads for similar applications, the new “high-throughput” system has the ability to quickly process and… read more

Cell transplant restores vision

August 26, 2003

A blind man can see again after being given a stem cell transplant.

The operation transplanted corneal and limbal stem cells into his right eye.

Cell reprogramming decoded

June 30, 2010

Uniquely labeled inducible fibroblast populations during a reprogramming process (AFTAU)

Scientists at Tel Aviv University in collaboration with researchers at Harvard University have succeeded in tracking the progression of cell reprogramming (the process of coaxing adult cells to revert to an embryonic stem cell-like state, allowing scientists to later re-differentiate these cells into specific types with the potential to treat medical disorders).

They used flourescent markers to develop their live imaging approach. During the reprogramming process, the team was… read more

Cell Repair Nanorobot Design And Simulation

June 8, 2004

A new Russian study by Svidinenko Yuri simulates cell-repair nanorobots. Yuri has generated several models based on the book Nanomedicine by Robert A. Freitas Jr.

Cell Phones, Reality Gaming

March 29, 2006

Games are becoming vastly more lifelike — more realistic. The addition of voice, initially driven by Xbox Live on consoles and TeamSpeak on PCs, is now improving to VoIP levels driven by Vivox.

A gaming platform called AI.Implant is helping to drive improvements in gaming AI. Implant specializes in easily giving game characters complex personalities so that the experience is more realistic. Characters act and react to players and… read more

Cell phones transforming health care in Africa

September 16, 2013


In a little over a decade, Africa has gone from a region with virtually no fixed-line telecoms infrastructure to a continent where one in six of the billion inhabitants now owns a cell phone, creating one of the largest, low-cost distributed sensor networks we’ve ever seen, with the potential to completely transform global health care, MIT Technology Review reports.

But ultimately the biggest impact may well come… read more

Cell Phones That Listen and Learn

(Dartmouth College)

SoundSense, which picks up sounds and tries to classify them into “voice,” “music,” or “ambient noise” categories, is a step in building a system that can learn user behavior on the go, say its Dartmouth College developers.

The software could allow for giving users feedback on their daily activities for health, time-management, and life-logging applications.

Cell phones ‘possibly carcinogenic,’ says WHO’s International Agency for Research on Cancer

May 31, 2011

The WHO/International Agency for Research on Cancer (IARC) has classified radio frequency (RF) electromagnetic fields as possibly carcinogenic to humans (Group 2B), based on an increased risk for glioma, a malignant type of brain cancer associated with wireless phone use, IARC says.

From May 24–31, 2011, a Working Group of 31 scientists from 14 countries met at IARC in Lyon, France… read more

Cell phones could double as night vision devices

May 5, 2010

Franky So, a University of Florida engineering researcher, has developed a nickel-sized imaging device that uses organic light-emitting diode technology (similar to that found in cell phone or laptop screens) for night vision.

Unlike night vision goggles, which are heavy and expensive, the device is paper-thin, light and inexpensive, making it a possible add-on to cell phone cameras, even eyeglasses, once it is enlarged.

The imaging device replaces… read more

Cell phones as dangerous as drunk driving

July 3, 2006

A study by University of Utah psychologists found that drivers talking on cell phones, either handheld or hands-free, are more likely to crash because they are distracted by conversation.
