Source of molecular triggers in cutaneous T cell lymphoma identified

In a study published in the journal Blood, Yale scientists identify the molecular triggers that stimulate Cutaneous T Cell Lymphoma (CTCL) cells to clonally expand into large populations of malignant lymphocytes. CTCL is the most common adult malignancy of T lymphocytes, the white blo...

Growth in the sea comes down to a struggle for iron

...to the 1930s. However, it wasn't until 1989 in the journal Nature that oceanographer John Martin reported the first series of iron experiments that indicated iron was indeed the missing ingredient. And he went further than that. Since growing plants absorb carbon dioxide, a powerful greenhouse gas, he sugges...
