Zinc blood test could lead to early diagnosis of breast cancer

By - December 15, 2014 1 Picture
Early diagnosis of breast cancer could one day be possible via a simple blood test that detects changes in zinc in the body. Scientists have taken techniques normally used for studying climate change and planetary formation and shown that changes in the isotopic composition of zinc, which is detectable in breast tissue, may help identify a "biomarker" (a measurable indicator) of early breast cancer.

Vaccine self-assembles into 3D structure to better fight cancer and deadly infections

By - December 9, 2014 2 Pictures
Scientists have had some success activating the body's immune system to take the fight to cancer and other diseases, a process known as immunotherapy. Now, a new method developed by researchers at the Wyss Institute for Biologically Inspired Engineering at Harvard University could advance this form of treatment even further. The technique involves the injection of biomaterials that assemble into 3D scaffolds inside the body to accommodate huge amounts of immune cells, a process that could trigger an attack on deadly infections ranging from HIV to cancer to Ebola.

Plastic phantom shows space travel may be safer than thought

By - December 8, 2014 3 Pictures
A European Space Agency experiment aboard the International Space Station suggests that space travelers may have less to worry about when it comes to radiation ... thanks to a phantom. Called the Matroshka, the "phantom" is a plastic mannequin that is the key component of the first comprehensive study of the effects of radiation on astronauts on long-term space missions that indicates that the hazard may not be as severe as previously thought.

Resveratrol in red wine could help cut alcohol-related cancer risk

By - December 4, 2014 1 Picture
With the festive season upon us, many people will indulge in more alcohol than usual. The health risks of binge drinking (and embarrassing Christmas party behavior) aside, alcohol consumption is also a major risk factor for some cancers, including head, neck, esophageal, liver, breast and colorectal cancer. However, in a spot of good news, a recent study from the University of Colorado suggests that the chemical resveratrol found in grape skins and in red wine can help block the cancer-causing effects of alcohol.

Prototype device diagnoses prostate cancer in minutes

By - November 8, 2014 2 Pictures
European research organization Fraunhofer is set to present a prototype device for quickly diagnosing prostate cancer at the COMPAMED trade fair in Düsseldorf next week. Its creators claim that it can reliably determine whether changed tissue in the prostate is benign or malignant within just a minute-and-a-half, thanks to an on-board visual analysis of a sample gathered via biopsy.

New device delivers unprecedented view of cancer cells spreading

By - November 3, 2014 4 Pictures
There is not a lot known about how exactly tumor cells travel to different parts of the body to form secondary cancers, a process known as metastasis. But now engineers from John Hopkins University have created a device that is offering an entirely new perspective, allowing researchers an up-close look at the cells as they spread and potentially unearthing new methods of treatment.

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.

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.
