Google announces glucose-monitoring contact lens prototype

By - January 16, 2014 1 Picture
While we have seen the technology behind glucose-monitoring contact lenses develop over the least few years, getting them out of the lab and onto the eyes of diabetes sufferers has been a different story. With Google announcing its testing of a smart contact lens designed to measure glucose levels in tears, the search giant is looking to provide more effective management of the disease. Read More

Injectable nanoparticles maintain normal blood-sugar levels for up to 10 days

By - May 5, 2013 1 Picture
Aside from the inconvenience of injecting insulin multiple times a day, type 1 diabetics also face health risks if the dosage level isn’t accurate. A new approach developed by US researchers has the potential to overcome both of these problems. The method relies on a network of nanoscale particles that once injected into the body, can maintain normal blood sugar levels for more than a week by releasing insulin when blood-sugar levels rise.

Tiny biosensor could mean an end to daily finger sticks for diabetics

By - September 7, 2012 1 Picture
Despite promising developments in recent years, millions of type-1 diabetes sufferers worldwide still face the often-painful daily burden of finger sticks to test their blood glucose levels. Now researchers at the Fraunhofer Institute for Microelectronic Circuits and Systems (IMS) have developed a biosensor that provides a non-invasive way to measure blood glucose levels and can transmit its readings wirelessly to a mobile device.

Chemical that slows down the biological clock could lead to new drugs to treat diabetes

By - July 16, 2012 2 Pictures
Scientists have long suspected that metabolic disorders, such as type 2 diabetes and obesity, could be linked to our circadian rhythm or biological clock. For example, laboratory mice with altered biological clocks often become obese and develop diabetes. Now biologists at UC San Diego have discovered that a chemical, which affects the activity of a key protein that regulates our biological clock, can repress the production of glucose by the liver, offering a promising new direction for the development of a new class of drugs to treat diabetes.

Tiny implantable fuel cell harvests energy from the brain

By - June 25, 2012 1 Picture
A new implantable fuel cell that harvests the electrical power from the brain promises to usher in a new generation of bionic implants. Designed by MIT researchers, it uses glucose within the cerebrospinal fluid surrounding the brain to generate several hundred microwatts of power without causing any detrimental effects to the body. The technology may one day provide a whole new level of reliability and self-efficiency for all sorts of implantable brain-machine interfaces that would otherwise have to rely on external power sources. If proven harmless, the method could be used to power implants that could, among other things, help the paralyzed regain the ability to walk. Read More

Can starch fibers solve the bandage conundrum?

Should you rip it off fast or slow? Researchers at Penn State may have found the elusive third, painless option. Professor Greg Ziegler and research assistant Lingyan Kong have developed a process that spins starch into fine strands, creating fibers that could be woven into low-cost toilet paper, napkins and biodegradable bandages that don't need to be ripped off at all.

Biochip that measures glucose in saliva could mean an end to finger-pricking for diabetics

By - January 23, 2012 1 Picture
In order to measure their blood glucose levels, most diabetics must perform painful finger-prick tests on a daily basis. Hopefully, however, that may not always be the case. Scientists at Rhode Island’s Brown University are now developing a biochip, that could someday be used to assess the concentration of glucose molecules in a tiny sample of saliva. Read More

Naturally occurring compound helps reverse diabetes in mice

By - October 9, 2011 1 Picture
Researchers at the Washington University School of Medicine in St. Louis have reversed diabetes in mice using a compound that is made naturally in the body. After diabetic mice were given the naturally occurring compound, called nicotinamide mononucleotide (NMN), their normal blood sugar metabolism was restored. The researchers say their findings suggest it might one day be possible for people to take the compound like a daily vitamin to treat or prevent type 2 diabetes. Read More

Implants could be powered by blood sugar

By - July 19, 2011 1 Picture
While there’s no denying that implantable medical devices such as pacemakers save peoples’ lives, powering those implants is still a tricky business. The batteries in a standard pacemaker, for instance, are said to last for about eight years – after that, surgery is required to access the device. Implants such as heart pumps are often powered by batteries that can be recharged from outside the body, but these require a power cord that protrudes through the patient’s skin, and that keeps them from being able to swim or bathe. Now, however, scientists at Germany’s University of Freiburg are developing biological fuel cells, that could draw power for implants from the patient’s own blood sugar. Read More
