Scientists have developed drug-carrying nanoparticles capable of targeting cancer tissue in the lungs. By engineering the devices to release their payloads only once they reach the site of the tumor, the researchers hope to reduce the size of dosages required and also limit the side effects of conventional treatments.

Researchers have identified a promising new target in the battle against certain neurological diseases. A protein known as TREM2 has been proven effective in clearing away unwanted debris in the brain, the unchecked buildup of which can lead to both Alzheimer's disease and multiple sclerosis (MS).

Scientists have developed targeted, biodegradable nano "drones" to deliver anti-inflammatory drugs that heal and stabilize arterial plaque in mice. Their work could pave the way for more effective prevention of heart attack and stroke in humans caused by atherosclerosis, in which artery walls thicken and suffer reduced plasticity due to an accumulation of white blood cells.

Transplanting a human head onto a donor body may sound like the stuff of science fiction comics, but not to Italian doctor Sergio Canavero. He has not only published a paper describing the operation in detail, but also believes that the surgery could be a reality as early as 2017. Read More
The future of weight loss could look like this. Inject your muscles with a compound that helps them burn more calories than usual and then do your daily chores to shed those extra pounds. That's the vision of a team of scientists who are working on a muscle-targeted injection therapy to help overweight people lose weight easily, even with low to moderate exercise. Read More
Researchers at Tufts University School of Engineering and the University of Pavia (Italy) have developed a three-dimensional tissue made from porous silk, that’s capable of producing platelets for clinical use. The development is expected to have a significant impact on treatment of blood diseases. Read More
When someone suffers an injury that results in a severed nerve, the usual treatment involves sewing the two severed ends directly back together, or bridging them by suturing in a nerve graft. Such repairs don't always function perfectly, however. What works better is to let the two ends grow back into each other. Scientists at the University of Sheffield have developed a means of helping them do so, in the form of a 3D-printed nerve guidance conduit (NGC). Read More
Researchers from MIT claim to have developed an easy-to-use blood test that can be applied in the field, allowing for the screening of multiple diseases at once. The test is said to provide results in around 10 minutes, and could be instrumental in stopping the epidemic spread of fatal diseases such as Ebola. Read More
Each year, hundreds of millions of people in developing countries are affected by parasitic diseases. One of the most common is malaria, which kills more than a million people annually, mostly children under five years of age. Scientists are using satellite data combined with local health information uploaded into geographical information systems (GIS) to help developing countries better manage limited resources and target interventions in the fight against malaria and other deadly parasitic diseases.

Tissue plasminogen activator (tPA) is a drug commonly used by surgeons to bust open blood clots in a patient's bloodstream, but it does have its limitations. Once injected, there's no guarantee it will reach the site of the blood clot, and even then, having it arrive in the correct dosage can be tricky, with the risk of hemorrhage a very real possibility. Researchers have now found that using a new type of magnetic nanoparticle to deliver the drug offers a much more efficient journey to the site, promising to destroy blood clots 100 to 1,000 times faster and aid significantly in the prevention of heart attacks and strokes.
