On April 8, 2024, parts of Ontario, Québec, the Maritimes and Newfoundland will see a total eclipse of the sun. Here’s how to get ready for it.

Some parts of North America will witness a total solar eclipse in April 2024. This may seem far away, but you should think about preparing for this rare and fascinating phenomenon.

People produce endocannabinoids – similar to compounds found in marijuana – that are critical to many bodily functions

A THC-like substance that occurs naturally in humans and other vertebrates helps maintain immunity, memory, nerve function and more – and research suggests a lack of it can harm health.

Cancer evolution is mathematical – how random processes and epigenetics can explain why tumor cells shape-shift, metastasize and resist treatments

An epigenetic model of cancer that incorporates the concept of stochasticity could also explain why cancer risk increases with age and how biological development can be reversible.

Cells routinely self-cannibalize to take out their trash, aiding in survival and disease prevention

Cells degrade and recycle damaged parts of themselves through a process called autophagy. When this “self-devouring” goes awry, it may promote cancer and neurodegenerative disease.

Microbes in your food can help or hinder your body’s defenses against cancer – how diet influences the conflict between cell ‘cooperators’ and ‘cheaters’

Cancer cells are ‘cheaters’ that do not cooperate with the rest of the body. Certain microbes in your diet can either protect against or promote tumor formation by influencing cell cooperation.

Stopping the cancer cells that thrive on chemotherapy – research into how pancreatic tumors adapt to stress could lead to a new treatment approach

Some cancers are notoriously resistant to chemotherapy and not curable with surgery. Stopping tumors from adapting to the harsh microenvironments of the body could be a potential treatment avenue.
