A new system for growing heart tissue in the lab may make future heart, liver, and lung repair much easier. University of Toronto scientists have developed asymmetrical honeycomb-shaped 2D meshes of protein scaffolding that stick together like Velcro and imitate the environments in which tissue and muscle cells grow in the body.
In order to treat injured joints, patients are often advised to apply
heat. This typically takes the form of a hot water bottle or
microwavable hot pack (which are cumbersome and cool off) or a heating
pad (which needs to be plugged in). Now, however, scientists from Korea
and the US have created a battery-powered thin mesh that applies heat
and stays put.
Future cancer treatments may target your genes rather than the cancerous cells themselves. A new study found that reactivating a single gene was enough to stop and reverse colorectal cancer (that's cancer of the colon, or bowels) in mice, with a return to normal intestinal functions within just four days and tumors gone within two weeks. The concept, though not the specific method, could lead to new treatments of a variety of cancers.
A team of graduate students at Johns Hopkins University has created a prototype device that delivers non-invasive brain stimulation to sufferers of Parkinson's disease. The brain-zapping headwear, dubbed STIMband, helps to reduce the severity of symptoms without requiring a visit to a hospital or doctor's office.
A team of MIT researchers has discovered a new target for drug treatments for prevalent diseases such as malaria. The findings focus on a membrane between the parasite and its host cell, with scientists successfully identifying a family of proteins that, when targeted, could cut off nutrients to the parasite.
Researchers at the University of California, Davis have developed and tested a molecule that has the ability to disrupt the body's regulation of cancer cells, causing the cells to self-destructing rather than multiply. The method was found to be effective when tackling dormant brain cancer cells that existing treatments are ineffective at eradicating.
