Journaling a sentence a day can make you happier
It can boost your memory too.
Most people (myself included) have started and stopped a journal or a diary quite a few times over the course of their lives. The idea of a personal log sounds romantic, but in our hectic lives, it's hard to sit down and etch out your day in so many words. But what about just one sentence a day?
The suggestion comes via Gretchen Rubin, author of The Happiness Project. In her latest podcast on happiness, she suggests people write one sentence a day — think of it as a personal tweet or CliffNotes encompassing the last 24 hours. For those of you that think one sentence a day may be too little to help manage a day full of things, Rubin claims it's just enough. Take it from her — she has been keeping a one-sentence journal for over a decade.
When I look back on it, you know, years later, like that one sentence really does keep memories vivid.
Rubin believes that reliving these daily moments can help make us happier people, and keeping a one-sentence journal is an accessible way to do that. What's more, recent research suggests it will make you happier. Writing about personal experiences, as the New York Times reported, improves mood disorders, boosts memory, and even reduces the number of doctors visits a person makes.
As she explains in her Big Think interview, Rubin sees happiness as an elusive concept. There are 15 different academic definitions of happiness, so rather than achieve a specific kind of happiness, take small, concrete steps toward feeling happier:
"Even people who deny the possibility of being happy, if you say do you think you could be happier? They'll say, 'Yeah, I could be happier.' Sometimes I think it's easier to think about being happier, for whatever that means to you then worrying about what is happiness and what would life be if I finally achieved this ultimate happiness?"
What can 3D printing do for medicine? The "sky is the limit," says Northwell Health researcher Dr. Todd Goldstein.
- Medical professionals are currently using 3D printers to create prosthetics and patient-specific organ models that doctors can use to prepare for surgery.
- Eventually, scientists hope to print patient-specific organs that can be transplanted safely into the human body.
- Northwell Health, New York State's largest health care provider, is pioneering 3D printing in medicine in three key ways.
It's a "canary in the coalmine," said one climate scientist.
- A team of researchers discovered that permafrost in Northern Canada is melting at unusually fast rates.
- This could causes dangerous and costly erosion, and it's likely speeding up climate change because thawing permafrost releases heat-trapping gasses into the atmosphere.
- This week, Canada's House of Commons declared a national climate emergency.
One of Stephen Hawking's predictions seems to have been borne out in a man-made "black hole".
- Stephen Hawking predicted virtual particles splitting in two from the gravitational pull of black holes.
- Black holes, he also said, would eventually evaporate due to the absorption of negatively charged virtual particles.
- A scientist has built a black hole analogue based on sound instead of light.
Not every part of a satellite burns up in reentry. Considering the growing number of satellites in orbital space, that's a big problem.
- Earth's orbital space is getting more crowded by the day.
- The more satellites and space junk we put into orbit, the greater a risk that there could be a collision.
- Not all materials burn up during reentry; that's why scientists need to stress test satellite parts to ensure that they won't become deadly falling objects.
