A team of physicists from McMaster University has developed a process to modify red blood cells so they can be used to distribute drugs throughout the body, which could specifically target infections or treat catastrophic diseases such as cancer or Alzheimer's.

For the first time, research shows that the contacts between cells, known as cell adhesion, are essential for cells to survive stress. The findings also suggest that impaired cell adhesion may sensitize cancer cells to drugs that damage cell proteins and cause stress.

UK scientists have identified a new way to kill pancreatic cancer cells by 'pulling the plug' on the energy generator that fuels calcium pumps on their cell surface. The study reports how switching off the cancer's energy supply causes the pancreatic cancer cells to become 'poisoned' by an irreversible build-up of calcium.

A new study sheds fresh light on how melanoma cells interact with other cells via extracellular vesicles they secrete. The researchers found that extracellular vesicles secreted by melanoma cells use the so-called hedgehog signalling pathway to intensify the malignant properties of the cells they are targeting. The discovery can help in the development of better treatment and diagnostics for melanoma.

Mathematics and science Braille textbooks are expensive and require an enormous effort to produce -- until now. A team of researchers has developed a method for easily creating textbooks in Braille, with an initial focus on math textbooks. The new process is made possible by a new authoring system which serves as a 'universal translator' for textbook formats. Based on this new method, the production of Braille textbooks will become easy, inexpensive, and widespread.

A woman's supply of eggs is finite, so it is crucial that the quality of their genetic material is ensured. New work elucidates a mechanism by which, even before birth, the body tries to eliminate egg cells of the poorest quality.

In a new study conducted in mice, researchers found that tobacco smoke from a hookah caused blood to function abnormally and be more likely to clot and quickly form blood clots. The findings provide new evidence that hookah smoking may not be a safe alternative to cigarettes.

Many medical experts have long believed that women simply 'catch up' to men in terms of their cardiovascular risk, but new research shows for the first time that women's blood vessels age at a faster rate than men's. The findings could help to explain why women tend to develop different types of cardiovascular disease and with different timing than men.
