Japan Earthquake Quickens Earth's Rotation
By changing the distribution of mass on Earth, Japan's earthquake sped up the planet's rotation, shortening the day by 1.8 microseconds, N.A.S.A. geophysicist Richard Gross has found.
The distribution of Earth's mass due the shifting tectonic plates around Japan was so significant that the speed of the planet's rotation has increased: "The intense temblor has accelerated Earth's spin, shortening the length of the 24-hour day by 1.8 microseconds, according to geophysicist Richard Gross at N.A.S.A.'s Jet Propulsion Laboratory in Pasadena, California. ... The scenario is similar to that of a figure skater drawing her arms inward during a spin to turn faster on the ice. The closer the mass shift during an earthquake is to the equator, the more it will speed up the spinning Earth."

A growing body of research shows promising signs that the keto diet might be able to improve mental health.
- The keto diet is known to be an effective tool for weight loss, however its effects on mental health remain largely unclear.
- Recent studies suggests that the keto diet might be an effective tool for treating depression, and clearing up so-called "brain fog," though scientists caution more research is necessary before it can be recommended as a treatment.
- Any experiments with the keto diet are best done in conjunction with a doctor, considering some people face problems when transitioning to the low-carb diet.
She met mere mortals with and without the Vatican's approval.
- For centuries, the Virgin Mary has appeared to the faithful, requesting devotion and promising comfort.
- These maps show the geography of Marian apparitions – the handful approved by the Vatican, and many others.
- Historically, Europe is where most apparitions have been reported, but the U.S. is pretty fertile ground too.
Thinking your life is worthwhile is correlated with a variety of positive outcomes.
- A new study finds that adults who feel their lives are meaningful have better health and life outcomes.
- Adults who felt their lives were worthwhile tended to be more social and had healthier habits.
- The findings could be used to help improve the health of older adults.
