Science Reverses Aging in Mouse
A frail mouse with failing organs was restored to vibrant youth when researchers re-activated production of the enzyme telomerase. Discovery News on the recently reported findings.
Researcher Ronald DePinho, director of the Belfer Institute of the Dana-Farber Cancer Institute, and colleagues at Harvard Medical School engineered mice that did not produce the enzyme telomerase, a chemical which protects the ends of DNA strands from being lost during replication. In an earlier study, these mice died after only six months, compared to the three-year life span of a normal mouse. But in DePinho's recent study, a chemical fountain of youth was given to the mice when they received special form of estrogen. The mice were engineered to produce telomerase only when this special estrogen was present.

Abraham Maslow was the 20th-century American psychologist best-known for explaining motivation through his hierarchy of needs, which he represented in a pyramid. At the base, our physiological needs include food, water, warmth and rest.
Using a new process, a mini-brain develops retinal cells.
- Mini-brains, or "neural organoids," are at the cutting edge of medical research.
- This is the first one that's started developing eyes.
- Stem cells are key to the growing of organoids of various body parts.
Does believing in true love make people act like jerks?
- Ghosting, or cutting off all contact suddenly with a romantic partner, is not nice.
- Growth-oriented people (who think relationships are made, not born) do not appreciate it.
