The skin of a banana has been used to great comic effects in numerous slapstick routines for many years. It's also good for the skin and is a traditional cure for warts. You can polish shoes and silver with it. You can make wine with it and it's even been known to find itself being dried, wrapped in paper and smoked. Now, research published in the journal of the American Chemical Society claims that mashed up peel can remove heavy metals from river water. Read More

Transcranial magnetic stimulation (TMS) is a technology that temporarily activates – or inactivates – parts of the brain using magnetic stimulation. Its ability to selectively turn areas of the brain on or off allows the functions and interconnections of the brain to by studied in a noninvasive and painless manner. Now researchers have shown that the technology can be used to enable rats to learn more easily. While smarter rats probably aren’t high on anyone’s wish list, the technology shows potential for allowing TMS to better treat a variety of brain disorders and diseases in humans, such as severe depression and schizophrenia.

Call me crazy, but I’ve always found some peace of mind knowing that the latest medical gadget scanning some worrisome part of my body isn’t an accessory for a smartphone, but costs in the millions of dollars and is the result of years of expensive research and development. However, as someone who has more than their fair share of moles dotted all over their body, I’m willing to make an exception for the handyscope. Consisting of an optical attachment and an accompanying app, the handyscope turns an iPhone into a digital dermoscope to provide an instantaneous up close look at potential skin cancers. Read More

Respected medical journal Lancet has taken a retrospective look at the past century and found that despite incredible advances in the field of medicine, some common issues persist. Problems identified in 1911 that strike a familiar chord today include the quest to understand and eventually cure cancer, an economic depression and it's negative effect on healthcare delivery and the plight of African nations. Challenges faced in first world countries included the impacts of illicit drug addiction, occupational health and workers' compensation issues, the need for better education of doctors, and the continued prevalence of curable and preventable diseases.

There are definitely two schools of thought as to whether or not humans should have meat in their diet, but even many non-vegetarians claim that the production and consumption of animal protein could definitely stand to at least be scaled back, both for environmental and health reasons. It has been estimated that it takes 40 square meters (48 sq. yards) of land to produce one kilogram (2.2 lbs) of meat, while 120 kilograms (265 lbs) of carrots or 80 kilograms (176 lbs) of apples could be raised within that same space. Obesity and cardiovascular disease, meanwhile, have been linked to high-fat diets – diets which often include things like sausages and hamburgers. With concerns like these in mind, researchers from Germany’s Fraunhofer Institute for Process Engineering and Packaging have developed food ingredients derived from lupin seed proteins, that can reportedly stand in quite convincingly for both milk and animal fat.

A 2008, researchers led by György Horvath MD, PhD, found that dogs could be trained to literally sniff out cancer. In their study, the researchers were able to train dogs to distinguish different types and grades of ovarian cancer, including borderline tumors. Horvath, together with professor Thomas Linblad from KTH Royal Institute of Technology and researcher Jose Chilo from Gävle University, has now created an electronic nose that can accomplish the same task.

An HIV-infected man who received stem cell treatment for leukemia from a donor with natural resistance to HIV infection appears to have been cured of HIV, according to a report on the NAM aidsmap website. The treatment, which was carried out in 2007, opens the possibility of a cure for HIV infection through the use of genetically engineered stem cells. Read More

New research published in two studies suggests that smoking may also affect another vital organ: the brain. In one study, smoking was found to thin the brain cortex in an area suggested to be linked to addiction, meaning long-term smokers could become more prone to addiction the longer they continue to smoke. In the second, successful quitters were found to enjoy the most happiness during periods of abstinence, while a subsequent return to smoking was found to depress mood, suggesting that perceived psychological dependence on smoking as a mood enhancer is in fact quite the reverse.

The aging process - it's undignified, unwanted, and many would say unnecessary. After all, the cells in your body are constantly replacing themselves - why can't they do it without causing progressive degradation of organs that lead to discomfort, weakness and death? Well, perhaps they can. Harvard scientists have discovered that by controlling certain genetic processes in mice, they can not only slow down the aging process, but "dramatically" reverse it throughout the body. It's a massive discovery, but it won't be able to be used in humans yet without some pretty scary consequences. Read More
