New compound triggers immune response to range of RNA viruses, including Ebola and hep C

Though important advances have been made in treating RNA virus infections such as hepatitis C and influenza, a broad spectrum antiviral drug that throws a blanket over all of them, including more deadly variants like Ebola, has remained out of reach. Scientists are now reporting the discovery of a drug-like molecule that could be used to combat all RNA viruses, by triggering an innate immune response that suppresses and controls the infections.Read More

Study shows that environment and behavior contribute to the majority of cancers

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.Read More

New hydrogel aids skin regeneration to improve wound healing

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.Read More

Engineered fat cells slip through blood-brain barrier to illuminate early-stage tumors

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.Read More

Diagnosis technique that filters out harmful cells could lead to a "dialysis machine" for cancer

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.Read More

Expandable sponge-filled syringe that stems bleeding cleared for civilian use

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.Read More

Implant could bring tears of joy to "dry eye" sufferers

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.Read More

Triple drug nanoparticle delivery may lead to better cancer treatments

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.Read More
