This study reveals a mechanism by which the environment, diet in this case, can influence cancer risk.

Imagine an army of self-propelling, radioisotope-covered particles 2,500 to 10,000 times smaller than a speck of dust that, upon injection into the body, search for and attach themselves to cancerous tumours, destroying them. Sounds like science fiction? Not so for mice with bladder cancer.
Researchers in Spain report that nanoparticles containing radioactive iodine and which propel themselves upon reaction with urea have the ability to distinguish cancerous bladder tumours from healthy tissue. These “nanobots” penetrate the tumour’s extracellular matrix and accumulate within it, enabling the radionuclide therapy to reach its precise target. In a study conducted at the Institute for Bioengineering of Catalonia (IBEC) in Barcelona, mice receiving a single dose of this treatment had a 90% reduction in the size of bladder tumours compared with untreated animals.
This novel approach may one day revolutionize the treatment of bladder cancer. Bladder cancer is the tenth most common cancer in the world, with over 600,000 new cases diagnosed in 2022 and more than 220,000 deaths globally, according to the World Health Organization’s Global Cancer Observatory.
Australian researchers have worked out how to fix a defect that causes lupus, and hope their world-first discovery will offer effective long-term treatment.
Published in Nature Communications, the Monash University-led study found a way to reprogram the defective cells of lupus patients with protective molecules from healthy people.
Using human cells, the new treatment restores the protective side of the immune system that prevents autoimmunity, which is when the immune system attacks its own cells.

Gallbladder Cancer Treatment

Types of treatment for gallbladder cancer include surgery, radiation, and chemotherapy. Treatment of gallbladder cancer that has spread to other parts of the body, cannot be removed by surgery, or has come back after treatment is often within a clinical trial. Find out about treatment options for gallbladder cancer.
A UC Davis Health study found that a single dose of Bacillus Calmette-Guérin (BCG), the vaccine for tuberculosis (TB), reduced liver tumor burden and extended the survival of mice with liver cancer. The study, published in Advanced Science, is the first to show the promising effects of the vaccine in treating liver cancer.
Hepatocellular carcinoma (HCC) is the most common type of liver cancer. It is also the third leading cause of cancer-related deaths worldwide. Current therapies include surgery, radiotherapy, chemotherapy, immunotherapy and liver transplant. Yet, the therapy outcomes for liver cancer remain bleak.
BCG, the century-old TB vaccine, is derived from the live bacteria Mycobacterium bovis. It is considered safe and widely used around the world.
A few years ago, a team of researchers working under Professor Stanisa Raspopovic at the ETH Zurich Neuroengineering Lab gained worldwide attention when they announced that their prosthetic legs had enabled amputees to feel sensations from this artificial body part for the first time.
Unlike commercial leg prostheses, which simply provide amputees with stability and support, the ETH researchers’ prosthetic device was connected to the sciatic nerve in the test subjects’ thigh via implanted electrodes.
This electrical connection enabled the neuroprosthesis to communicate with the patient’s brain, for example relaying information on the constant changes in pressure detected on the sole of the prosthetic foot when walking. This gave the test subjects greater confidence in their prosthesis—and it enabled them to walk considerably faster on challenging terrains.
An innovative computer model of a human lung is helping scientists simulate, for the first time, how a burst of radiation interacts with the organ on a cell-by-cell level.
This research, carried out at the University of Surrey and GSI Helmholtzzentrum für Schwerionenforschung, Darmstadt, could lead to more targeted treatments for cancer and reduce the damage caused by radiotherapy. The research is published in the journal Communications Medicine.
Dr. Roman Bauer, Senior Lecturer at the University of Surrey, said, “Doctors could one day use our model to choose the right length and strength of radiotherapy—tailored to their patient. This is exciting enough—but others could use our technique to study other organs. This could unlock all kinds of medical knowledge and could be great news for doctors and future patients.”
