Cancer

Researchers at the University of Pennsylvania have developed an electronic nose that may be able to sniff out signs of cancer from blood plasma samples. In tests, the device was able to detect a range of cancer types with over 90 percent accuracy.

Leveraging a newfound ability to identify the "fittest" metastatic cancer cells, scientists at the UK's University of Salford have discovered that an already approved drug can be deployed to cut off their fuel supply, while leaving normal healthy cells unharmed.

Our health inevitably declines as we age, but maybe we can slow it down. A new study has found that boosting a certain gene in mice can increase their lifespan and keep them in better health for longer by mimicking the effects of caloric restriction.

A new proof of concept study has demonstrated how certain types of protective gut bacteria can help negate the damaging side effects of toxic chemotherapy drugs, raising the prospect of future probiotics designed to enhance gut health in cancer patients.

In recent years effective new methods of cancer treatment are emerging. Now, scientists at the University of Konstanz have found that combining two experimental methods – a vaccine and an immunotherapy – helps boost the success rate in mouse models.

One of cancer’s crafty tricks involves manipulating the host’s immune cells to protect tumors instead of fighting them. Now researchers at Massachusetts General Hospital have turned the tables again, transforming these cells back into cancer killers.

Researchers in Canada have made a significant discovery relating to pancreatic cancer, pinpointing a protein that the cancer cells rely on for growth, and demonstrating how targeting them can inhibit tumor growth in the lab.

Researchers at Indiana University have linked a protein secreted by the stomach to obesity. In tests in mice, the team switched off the protein and found that it reduced the animals’ body fat levels, even when fed a high-fat diet.

Scientists have developed a tiny first-of-its-kind imaging sensor designed to build detailed 3D maps of cellular structures inside the body, potentially revealing stiffness and abnormalities that may be indicative of cancer.

Scientists at Cambridge have demonstrated a new method to fight leukemia, by targeting overactive enzymes that can lead to the disease. If the results of mice tests carry across to humans, it could be the first of a new class of cancer drugs.

We all know exercise is good for us, but recently, scientific studies have started to shine a light on how regular physical activity can benefit human health in ways you might not expect. Let's take a look at some interesting examples.

Several hundred million people around the world have safely received a wildly effective COVID-19 vaccine based on mRNA technology. So what exactly is an mRNA vaccine, where did the technology come from, and what other diseases could it be useful for?
