Cancer cells have gone rogue and are dividing unchecked, and now Australian researchers have designed a new molecule that may put a stop to that. It targets a protein called PCNA, a donut-shaped structure that plays a key role in cell division, which could lead to a new class of cancer treatments.

Melanoma, a common type of skin cancer, is traditionally detected via observing changes in irregular moles, and then conducting a skin biopsy. A team has now developed a blood test that can detect melanoma in its early stages, reducing the need for expensive, and frequently unnecessary biopsies.

A fascinating cancer detection technique has been developed by scientists at Stanford University. The process involves a small magnetic wire being inserted into a vein where it attracts free-floating tumor cells in the blood.

Researchers at CNBP have developed a new targeted treatment for cancer. Chemotherapy drugs are wrapped in “nano-bubbles” called liposomes, which are then injected into the desired part of the body and made to release their payload on demand, by applying X-ray radiation.

A jury in St. Louis has awarded US$4.69 billion to 22 women who were claiming Johnson & Johnson’s talcum powder products contained asbestos and induced ovarian cancer. Despite the weak and inconclusive scientific links, this is the largest payout yet in a series of ongoing court cases on the topic.

A promising new cancer drug delivery system has successfully passed early human safety trials. The treatment delivers cancer drugs in heat-activated capsules to tumors in the liver and then uses a focused ultrasound beam to remotely trigger the targeted release of their drug payload.

A fascinating study has found that the ketogenic diet may improve the efficacy of a new class of cancer drug that has been inexplicably showing disappointing results in early human clinical trials.

Scientists are coming up with some creative ways to fight cancer. Researchers at the University at Buffalo have developed new kinds of nanoparticles that can infiltrate, heat up and kill cancer cells more effectively and efficiently than similar methods.

Researchers have recently revealed the results from a Phase 1 trial investigating the efficacy of an experimental treatment using a genetically modified poliovirus to attack a lethal form of brain cancer. The results are mildly promising but don’t suggest this will be a magic bullet of a treatment.

"World’s smallest computer” is a contentious title, not just because scientists are racing to shrink devices, but because the very definition of a computer could be up for debate. The latest claim to the title is a tiny device that communicates through light and makes a grain of rice look gigantic.
