Back in January, a Johns Hopkins University study was released claiming that two-thirds of adult cancers are down to random mutations, or more simply put – bad luck. Now, a team of researchers from Stony Brook University is refuting that claim, providing an alternative analysis that counters the argument, stating instead that external factors actually play a much bigger role.
Researchers at Australia's University of New South Wales (UNSW) have come up with a new way of tackling harmful biofilms. The non-toxic method, which combines targeted nanoparticles with heat, could have a wide range of applications.
Healing chronic skin wounds can be difficult, particularly when they span large areas, or when healing is complicated by health problems such as a lack of mobility. A team of researchers from the University of California, Los Angeles (UCLA) has worked to improve the process, creating a more effective method of regeneration through use of a new material that creates a porous scaffold, allowing wounds to heal more effectively.
Cancerous growths that arise from the supportive tissue of the brain, known as gliomas, account for around 30 percent of all brain tumors and carry an average survival rate of just 14 months. These aggressive tumors are difficult to detect through MRI, largely due to the the protective blood-brain barrier that stops contrast agents from entering and lighting them up. But a new type of engineered fat cell could make them more treatable, by penetrating the barrier and revealing their presence at a much earlier stage of development.
Before cures for diseases such as Alzheimer's can be found, scientists need to develop a better understanding of how neurons in the brain communicate with one another. Researchers at the University of Michigan recently took a step towards that goal, by developing what are said to be the smallest LED probes ever implanted in a living brain.
A new cancer diagnosis technique that separates cancerous cells from blood may inspire a new form of treatment for the disease. A researcher at Australia's University of New South Wales (UNSW)who helped devise the test says it could potentially be scaled up to cleanse meaningful quantities of blood, which could then be reintroduced into the body to battle different forms of the disease.
A fast-acting medical device developed for emergency treatment of a gunshot or other penetrating wound on the battlefield has been cleared for civilian use by the US Food and Drug Administration (FDA). The XStat 30 is a plastic syringe that can stop severe bleeding within around 20 seconds through the injection of small sponges into a wound, and will now be available for use by the general population.
Caused by a lack of proper tear fluid, dry eye syndrome is among the world's most common eye diseases. Although it rarely results in complete vision loss, it is painful, and can lead to ulcers or scars on the cornea. There may be new hope for sufferers of the condition, however. Scientists from Stanford University have created an implant that causes the eye to produce more tears.
Scientists from Oregon State University have developed a new delivery system for cancer treatment that attacks the condition simultaneously with three different drugs. According to the team, it's likely to prove particularly effective against cancers that spread through the lymphatic system, such as metastatic melanoma.
A recent study from researchers at the University of Oxford has looked at using a new technique to scan patients' hearts, without the need to inject a potentially dangerous substance. The method could significantly improve treatment, providing imagery that's much easier for doctors to understand.
