Sweat-monitoring patch releases diabetes drugs when required

Unlocking the secrets that sweat contains about our bodies could come to offer all kinds of exciting ways to maintain our physical well-being. From glucose to sodium, tracking of key chemicals in this bodily fluid could make for new, non-invasive ways to keep tabs on harmful conditions. The latest effort to tap into this assortment of physiological information comes in the form of a sweat-monitoring patch that records glucose in a subject and even releases diabetes drugs into the bloodstream to keep its levels in check.Read More

Laser-based blood glucose monitor promises a less prickly way to keep diabetes in check

For a number of years now, various research groups have been examining the potential for lasers applied to the skin to measure blood-glucose levels in an effort to put an end to the daily finger-pricks and meticulous blood sampling performed by diabetics. Japanese scientists have now developed one such system that differs from previous techniques by relying on far infrared light, which the researchers say is harmless and offers unprecedented levels of accuracy.

Electrical contact lens eyes glucose monitoring and augmented reality

Smart glasses haven't quite taken off as some might have hoped, but that doesn't mean another form of eyewear can't offer users a worthy augmented reality experience. Australian scientists have developed an electrically conductive contact lens with the potential to host miniature computer displays and sensors to help monitor health.Read More

Researchers produce hydrogen quickly and cheaply using plant waste

Hydrogen is the ideal gas for use in low-emissions combustion engine or fuel cell-powered vehicles, due to its almost non-existent greenhouse gas emissions. Production costs, however, are higher compared to gasoline and around 95 percent of it is currently produced, somewhat counter-intuitively, from fossil fuels. Now researchers at Virginia Tech claim to have created a method to produce hydrogen fuel using a biological technique that is not only cheaper and faster, but also produces hydrogen of a much higher quality ... and all from the leftover stalks, cobs, and husks of corn.

MRI-based cancer detection technique could replace biopsies

While non-invasive imaging technologies, such as mammograms or CT scans, are capable of detecting tumors, identifying whether they are malignant or benign usually involves getting out the scalpel and conducting a biopsy. Now researchers at Johns Hopkins University have developed a technique that uses magnetic resonance imaging (MRI) to noninvasively detect cancerous cells, offering the potential of supplementing biopsies or maybe one day replacing them altogether.Read More

Saccharin could sweeten the deal for cancer-fighting drugs

Whether it be advice from a dentist or preparing their body for beach season, there's a host of reasons people might reach for an artificial sweetener rather than sugar – though its cancer-fighting properties are unlikely to be one of them. But new research shows that the common sugar substitute known as saccharin could hamper the growth of particular cancers, with scientists claiming it could form the basis for new kinds of drug treatments.Read More

MIT researchers develop glucose-responsive diabetes treatment

Researchers at the Massachusetts Institute of Technology (MIT) have developed a new method for tackling diabetes that could represent a significant breakthrough in treating the condition. The team's engineered insulin stays in the patient’s bloodstream, but is only activated when sugar levels start to tip the scales. Read More

Hormone combo a triple threat to obesity and adult-onset diabetes

In 2012, we covered work led by Professor Richard DiMarchi that showed linking two hormones into a single molecule held promise as a treatment for obesity. DiMarchi followed this up last year by combining the properties of two endocrine hormones to provide an effective treatment for both obesity and adult-onset diabetes. Continuing in this vein, DiMarchi has now co-led a study whereby obesity and diabetes were effectively cured in lab animals by adding a third hormone to the molecular mix.Read More

Chameleon-like gel could track blood sugar levels in real time

Thanks to a new color-changing hydrogel, there may soon be a more reliable way of continuously monitoring the blood glucose levels of both diabetics and hospital patients. If incorporated into a device such as an implanted pump, it could automatically trigger the release of insulin into the bloodstream as needed. Read More
