Farmers across the world produce between 10 and 13 million tons of field pea every year. That makes it a top legume crop, just behind dry beans and chickpeas.

Arthritis is the most-widespread joint disease, with around 90 percent of all people over 65 being affected to varying degrees, but this degenerative disease is also widespread amongst younger people. In arthritis, the cartilage in the joint, a type of protective layer on bones that "lubricates" the joint, degenerates over time. This can be extremely painful for sufferers, because inflammatory reactions are associated with cartilage degeneration. In the later stages of the disease, bones are no longer adequately protected and can directly rub against each other.

Arthritis can affect all joints in the body, but most often affects the knee joint, hip joint and fingers. The disease has been considered incurable until now. Current treatment methods, such as anti-inflammatory drugs and painkillers, mainly address the symptoms. Often, the only remaining option is an operation to replace the affected joint with an artificial one.

Infection with human papilloma virus (HPV) is the primary cause of cervical cancer and a subset of head and neck cancers worldwide. A University of Colorado Cancer Center paper describes a fascinating mechanism that links these two conditions – viral infection and cancer. The link, basically, is a family of enzymes called APOBEC3. These APOBEC3 enzymes are an essential piece of the immune system’s response to viral infection, attacking viral DNA to cause disabling mutations. Unfortunately, as the paper shows, especially the action of family member APOBEC3A can spill over from its attack against viruses to induce DNA mutations and damage in the host genome as well. In other words, this facet of the immune system designed to scramble viral DNA can scramble human DNA as well, sometimes in ways that cause cancer.
