Toxin-producing stem cells fight brain tumors where it matters most

By - October 27, 2014 1 Picture
When it comes to new tumor-fighting treatments, it’s often as much about location, location, location as it is the actual drug interaction. Cytoxin-producing stem cells produced by scientists at Harvard University lodge at the site of brain tumor removal to continually attack remaining tumor cells. As an alternative to drug treatments that can be invasive or ineffective, the researchers saw promising results against glioblastomas, which hold the dubious distinction of being the most common and most fatal brain cancer.

Surgeons successfully transplant a heart that had stopped beating

By - October 27, 2014 1 Picture
In a world first, surgeons at St Vincent’s Hospital in Sydney, Australia have successfully transplanted a "dead" heart into a patient. Thanks to the use of a revolutionary preservation solution, developed by the Victor Chang Cardiac Research Institute and St Vincent’s Hospital, the doctors were able to resuscitate and transplant the donor heart after it had stopped beating for up to 20-30 minutes.

Monkeybar project using aerial drones to get on top of malaria

By - October 26, 2014 2 Pictures
Over the last ten years, a new type of malaria has been on the rise in the forests of Southeast Asia, and experts are turning to new technologies to try and figure out why. By using drones to observe the environment from above, researchers are gaining a new perspective on how changes to the terrain may be impacting local wildlife and causing the spread of the disease.

Converting skin cells directly into brain cells advances fight against Huntington's disease

By - October 25, 2014 2 Pictures
Few diseases are as terrifying as Huntington's, an inherited genetic disorder that gradually saps away at sufferers' muscle control and cognitive capacity until they die (usually some 20 or so years after initial symptoms). But scientists at Washington University School of Medicine may have provided a new glimmer of hope by converting human skin cells (which are much more readily available than stem cells) directly into a specific type of brain cell that is affected by Huntington's.

Sweat-analyzing skin patch could replace blood sampling

By - October 23, 2014 2 Pictures
Nobody likes having blood samples drawn. What's more, such samples typically have to be analyzed in a lab before they're able to tell us anything. Now, however, scientists at the University of Cincinnati and the US Air Force Research Laboratory are developing a system in which a Band-Aid-like skin patch is able to gather and transmit medical data in almost real time, by analyzing the patient's sweat ... and you just need a smartphone to read it, no poking or prodding required.

Research suggests there may be an off switch for drug resistance in cancer cells

By - October 22, 2014 2 Pictures
In cancer treatments such as chemotherapy, hundreds of thousands of cancerous cells are killed off. But if even one of these cells has a unique mutation, it can survive the treatment and start to multiply, giving rise to a set of more drug-resistant cells. Researchers at the Salk Institute in California have now gained new insights into what exactly is causing these variations in the cells, suggesting there may in fact be a way of switching off the mechanism and improving treatment effectiveness.
