Researchers at Canada's McGill University have uncovered what could be a pretty sweet way of warding off bacteria. The scientists developed a concentrated extract of maple syrup and combined it with antibiotics, finding that it heightened bacteria's vulnerability, suggesting it could prove an effective way of lowering dosages required to treat infections and help to hamper the evolution of drug-resistant superbugs.

One of the body's defenses against deadly cancer cells may have just received a much-needed boost. Researchers at Imperial College London have happened upon a previously unknown protein that ramps up the presence of all-important cytotoxic T cells, which destroy virus-infected and cancerous cells.

Though generally a bacteria we'd associate with a severe bout of food poisoning, previous research has suggested that Salmonella needn't always bring bad news and stomach cramps. Certain strains have been shown to kill off cancer cells, but to use them as a form of treatment for humans without inducing any nasty side effects has so far proven difficult. But now, researchers have developed genetically modified salmonella that turns toxic only after it enters a tumor. Read More
Two years ago we heard about the Nanostim, a pacemaker that's less than 10 percent the size of a regular model. While it's pretty darn small, Medtronic's just-announced Micra TPS (Transcatheter Pacing System) is reportedly even tinier. Billed as the world's smallest pacemaker, it's described as being the size of a large vitamin capsule – and it can be implanted using a catheter. Read More
A team of MIT researchers has developed a new approach to attacking cancer, creating a method that allows two major branches of the immune system to work together. The new technique, which is known as cancer immunotherapy, has already proved successful in tests on laboratory mice. Read More
Our tissue's inability to repair itself as we grow older is thought to correlate with the decline in the presence of stem cells. So it follows that if stem cell function can be preserved beyond the norm, it could have implications for the aging process and adverse effects of tissue degeneration, such as cancer. Scientists from the University of Toronto have followed this line of thinking through research on the mammary glands of genetically modified mice, finding that development of the tissue can be manipulated to avoid the effects of aging.

In the not-too-distant future, burn victims may be able to recover in the half the time than is possible today. If so, it will be thanks to a biodegradable dressing that applies cultured skin cells directly to the wound site. Read More
A team of researchers from the University of Houston (UH) has developed an algorithm that enabled a man whose right hand had been amputated to grasp objects using a bionic hand controlled by his thoughts. While we've seen similar accomplishments in recent years, the new technique is non-invasive, capturing brain activity via a scalp EEG. Read More
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.

In the near future, it's entirely possible that babies with heart defects will be born with complete pacemakers already installed. That's because scientists at Children's Hospital Los Angeles (CHLA) and the University of Southern California have developed the world's first fully-implantable pacemaker for fetuses. Read More
