Roundworm infection, or toxocariasis, is a zoonotic disease — a disease that can be transmitted from animals to humans. Dogs and cats are the definitive hosts for the roundworm species that commonly cause human disease.
Cheating mitochondria can exploit cellular mechanisms for dealing with the scarcity of food in a worm, although this can decrease its wellbeing
Biological sex is typically understood in binary terms: male and female. However, there are many examples of animals that are able to modify sex-typical biological and behavioral features and even change sex.
Scientists have successfully dialed up and down the lifespan of creatures by changing the activity of proteins present in roundworm cells.
As we age, the immune system gradually becomes impaired. One aspect of this impairment is chronic inflammation in the elderly, which means that the immune system is constantly active and sends out inflammatory substances.
Scientists at USC Dornsife College of Letters, Arts and Sciences may have found the beginnings of a path toward increasing human lifespan.
Researchers from Kumamoto University, Japan have pinpointed the mechanism that regulates the balance between plant growth and defense.
As people get older, they often feel less energetic, mobile or active. This may be due in part to a decline in mitochondria, the tiny powerhouses inside of our cells, which provide energy and regulate metabolism.
