Protein Helps Cells Adapt—or Die
A cellular stress pathway called the unfolded-protein-response (UPR) both
activates and degrades death receptor 5 protein (DR5), which can promote or
prevent cell suicide, according to a paper published in Science today (July 3). The
theory is that initial stress blocks cell suicide, or apoptosis, to give the cell a chance
to adapt, but that if the stress persists, it eventually triggers apoptosis.

Aristotle
Aristotle (/ˈærɪˌstɒtəl/;[1] Greek: Ἀριστοτέλης [aristotélɛːs], Aristotélēs; 384–322 BCE)[2] was
a Greek philosopher and scientist born in the Macedonian city of Stagirus, in 384 BCE. His
father, Nicomachus, died when Aristotle was a child, whereafter Proxenus of Atarneus became his
guardian.[3] At eighteen, he joined Plato's Academy in Athens and remained there until the age of thirty-seven
(c. 347 BCE). His writings cover many subjects – including physics, biology, zoology, metaphysics, logic,
ethics, aesthetics, poetry, theater, music, rhetoric, linguistics, politics and government – and constitute the first
comprehensive system of Western philosophy. Shortly after Plato died, Aristotle left Athens and, at the request
of Philip of Macedon, tutored Alexander the Great between 356 and 323 BCE. According to the Encyclopædia
Britannica, "Aristotle was the first genuine scientist in history ... [and] every scientist is in his debt."
