​Virus "delivery trucks" flip disease-causing cells into healthy ones

It sounds like a scene from a sci-fi movie: Scientists create a weapon that neutralizes a bad invading entity and maybe even turns it into a force for good. That's a bit like what researchers at the University of California San Francisco (UCSF) have just done. Only in this case, the invaders are disease-causing liver cells and the "weapon" involves a bit more than special effects.Read More

Stem cell treatment reawakens limbs in wheelchair-bound stroke victim

While new tools have emerged to help rehabilitation along, the road back to a healthy life after suffering a stroke can be a long and challenging one. In research that could one day significantly cut recovery times for victims of these debilitating brain injuries, scientists have injected modified stem cells into the brains of patients and brought about substantial improvements to motor function, with one even regaining control of her limbs and leaving her wheelchair behind.

Trained immune cells raise prospect of universal cancer vaccine

Engineering immune cells to attack cancer is a form of treatment that is showing great promise, but it is complex because it involves extracting and modifying T cells before injecting them back into the body. Scientists have now demonstrated a way to not just arm immune cells while still inside the body, but equip them with the ability to fight any kind of cancer, providing an early proof-of-concept for a cheap, universal vaccine for the deadly disease.Read More

Wearables made to warn of asthma attacks

People with serious asthma already know to avoid certain activities or situations, but even then, attacks can still occur. That's why scientists at North Carolina State University are developing a wearable early warning system known as the Health and Environmental Tracker (HET). Consisting mainly of a wristband and chest patch, the technology monitors patients' bodies and their environment, sending an alert when an attack may be imminent.Read More

3D hydrogel biochips offer better diagnosis of early-stage bowel cancer

Early detection is paramount to survival from bowel cancer, but doing so is difficult because most symptoms don't present until the cancer matures. Worse, existing diagnostic tests tend to be invasive and traumatic. Russian scientists hope to change this with a new biochip technology that can gather better, more precise data for diagnostic analysis. The scientists report that their new method far outstrips traditional methods of diagnosing bowel cancer. Read More

New cancer treatment targets sick cells only

Chemotherapy is the standard treatment for cancer but it also causes strong side effects and kills not only cancer cells, but healthy ones, too. In order to mitigate the damage this type of therapy causes to a person already ravaged by illness, a team of Brazilian researchers is working a new technique to deliver drugs with more precision, so healthy cells are more likely to be spared from chemical onslaught.Read More

One pill to rule them all: 3D printing tech combines multiple drugs in a single pill

Remembering to take a pill once daily can be hard enough, but it gets particularly challenging when you have to take several doses throughout the day – especially if you're taking multiple types of medication. To make things easier, scientists at the National University of Singapore (NUS) have developed a new technique that uses a 3D printer to combine multiple doses of different medications in a single time-release tablet.Read More

Wound-plugging XStat syringe saves its first life on the battlefield

With the capacity to stem severe bleeding within around 20 seconds, the XStat sponge-filled syringe could be a real game-changer when it comes to medical care. It has just proved its worth in the most testing of environments, with battlefield surgeons successfully using the device to plug a soldier's gunshot wound for the first time. Read More

Is exercise an effective cancer therapy?

While it's well-known that regular exercise can help you avoid getting cancer in the first place, researchers now believe that it could also be useful in actually combating the disease. An upcoming study led by University of Montreal Hospital Research Centre (CRCHUM) researchers aims to provide a more concrete answer to the question – can exercise really help fight cancer?Read More

Sensor detects signs of cancer, Alzheimer's, and Parkinson's

Cancer and neurodegenerative diseases like Alzheimer's and Parkinson's are all able to be better treated if detected early. Unfortunately, this is not always the case as symptoms may not appear until these diseases are well established. To help counteract this problem, scientists at the National Nanotechnology Laboratory (LNNano) in Brazil have created a biosensor capable of rapidly detecting molecules specifically linked to various cancers and neurological diseases.Read More
