One of the greatest mysteries in life is death. In an attempt to understand what occurs in the last moments of life, scientists study the lives and deaths of animals, looking for clues that might be applicable to larger organisms. One such study, in London, examined worms. This article, from The Conversation & Ars Technica, discusses the finding: a blue light signaled the death of the worm. While in some cases, delaying the blue light could also delay death, it appeared it didn’t work in all cases. More details can be found at the link.
Great discoveries are not made all at once, but rather in little steps, one at a time. One such little step seems to have uncovered the pathway by which learning goes from temporary into long-term storage, thus establishing new pathways in the brain long into adulthood.
