A healthy endocannabinoid system is critical to the human body’s immune functions. Jose Luis Pelaez Inc/Digital Vision via Getty Images

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.
Stochasticity is everywhere – and finding the order in disorder can unlock new ways to understand biology. Erlon Silva - TRI Digital/Moment via Getty Images

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.

Triggering cancer cells to become normal cells – how stem cell therapies can provide new ways to stop tumors from spreading or growing back

Many tumors have cancer stem cells that help them grow and evade treatments. Differentiation therapy forces these cells to mature, stopping growth with less toxicity than traditional treatments.

How cancer cells move and metastasize is influenced by the fluids surrounding them – understanding how tumors migrate can help stop their spread

Counterintuitively, cells move faster in thicker fluids. New research on breast cancer cells explains why, and reveals the role that fluid viscosity plays in metastasis.

Chronic pain: An invisible disease whose sufferers are unfairly stigmatized

Although chronic pain is recognized by scientists as a disease in its own right, it remains largely under-recognized, under-diagnosed and, above all, associated with numerous prejudices.

Anti-cancer CAR-T therapy reengineers T cells to kill tumors – and researchers are expanding the limited types of cancer it can target

Immunotherapy has the potential to eliminate tumors, but works best for select patients. Engineering T cells to bypass cancer’s defenses could help expand treatment eligibility to more patients.
