Cancer Cell Deformability Drives Movement Through Tight Tissue Gaps

Aggressive cancer cells are masters of movement. When they spread through the body, they cause metastasis, which significantly reduces a person's chance of survival.

Discovery Reveals Greater Epigenetic Complexity in Unicellular Life

Multicellular organisms (animals, plants, human) all have the ability to methylate the cytosine © base in their DNA. This process, a type of epigenetic modification, plays an important role in conditions such as cancer and processes such as aging.

Sabotaging T Cell Exhaustion for Cancer Therapy

Like all hardworking things, the cytotoxic T lymphocytes (CTLs) of the immune system charged with detecting and destroying cancer cells tend to get very tired-so much so, in fact, that they can even die from exhaustion.

Researchers Discover Molecular Switch That Helps Breast Cancer Cells Survive Stress

Cells are regularly faced with environmental stresses that may damage or destroy them. To survive, they quickly adjust their gene expression to protect themselves.

Researchers Reveal How the Brain Forms Hidden-State Inferences

Animals survive in changing and unpredictable environments by not merely responding to new circumstances, but also, like humans, by forming inferences about their surroundings-for instance, squirrels understand that certain bird noises don't signal the presence of a predator, so won't seek shelter when they later hear these same sounds.

Blocking a Hidden Tumor Pathway Revives the Immune System

A new study has discovered a molecular signal that tumors exploit to exhaust the T cells meant to destroy them-and how silencing that signal could revive the body's immunity.
