It's been a puzzle why our two closest living primate relatives, chimpanzees and bonobos, have widely different social traits, despite belonging to the same genus.

Loss of glaciers and snowpack due to climate warming in alpine regions is putting pressure on a rare aquatic insect, the meltwater stonefly, according to a study recently released in Climatic Change Letters.

Research published in the Cancer Cell journal in March was a significant step in knowing the causes of cancer better, especially breast cancer, revealing that the lack or loss of a protein in the cells known as SIRT3, induces the proliferation of this disease and thereby, this protein can be an may be a therapeutic target in the development of effective therapies for cancer. The research was led by Dra. Marcia Haigis of the Harvard Medical School, with the participation of Dr. Arkaitz Carracedo, from the Proteomics Laboratory at CIC bioGUNE.
