Staying at elementary school for longer associated with higher student attainment

A new study has discovered that U.S. students achieve better results in reading and mathematics tests when they stay in elementary school for grades six (age 11–12) and seven (age 12–13), rather than transfer to middle school. In contrast, students in grade eight (age 13–14) achieve better results in middle school than high school.

Tumor resistance is promoted by anti-cancer protein

Lack of oxygen, or hypoxia, is a biological stressor that occurs under various conditions such as wound healing and stroke. To rescue the tissue, the body has innate mechanisms that "kick in" to make the cells of the hypoxic tissue more resistant and assist in tissue repair. One such mechanism is the expression of a protein called Hypoxia Induction Factor (HIF), which controls several processes such as glucose uptake, growth of blood vessels and cell proliferation. Despite its beneficial role in some diseases, HIF has also been found to be an important contributor towards cancer progression.
