Harvard study: Heat slows down the brain by 13%
As temperatures rise, your brain's processing power declines.
A Harvard study of 44 students has confirmed what each and every one of us who has ever been an adult human has learned: summer heat doesn't help you think.
Half the students lived in a building with air conditioning, and half didn't. They were all asked to take a cognitive assessment test on their phones right after getting up. The students with air conditioning did normally, while the students without air-conditioning, however, had 13.4% worse reaction times and coincidentally performed 13.3% worse on the cognitive tests.
The study was conducted over a 12-day period in the summer of 2016, during which there was a five-day heatwave. What's interesting is the heat continued inside long after the outside heat left. Since many buildings are built to retain heat during the winter, they have a tendency to keep all heat in, meaning that a non-airconditioned building can keep the heatwave going inside for sometimes up to 48 hours after the initial natural one. As someone that lived in a crappy Brooklyn building for a particularly brutal summer, I can attest to it getting up to 87ºF inside at night if you forgot to set the timer on the thermostat.
The study has socioeconomic findings, too: if you're too poor to afford air-conditioning you might fall behind at work or at school. In fact, studies are proving this repeatedly.
America, by and large, has an obsession with A/C... 87% of American homes have A/C. There are currently 1.6 billion A/C units in the world, and that figure is expected to be five times greater by 2050 as climate change takes its toll.
- Human beings are psychologically hardwired to fear differences
- Several recent studies show evidence that digital spaces exacerbate the psychology which contributes to tribalism
- Shared experiences of awe, such as space travel, or even simple shared meals, have surprising effectives for uniting opposing groups
The $100-million startup is moving ahead with an audacious vision for space exploration.
- The Breakthrough Starshot initiative was co-founded by Stephen Hawking.
- The project raised $100 million and is moving ahead with extensive research.
- The goal of Starshot is to send tiny "StarChip" spacecraft to explore neighboring star systems.
On Friday, NASA's InSight Mars lander captured and transmitted historic audio from the red planet.
- The audio captured by the lander is of Martian winds blowing at an estimated 10 to 15 mph.
- It was taken by the InSight Mars lander, which is designed to help scientists learn more about the formation of rocky planets, and possibly discover liquid water on Mars.
- Microphones are essentially an "extra sense" that scientists can use during experiments on other planets.
Astronauts will be able to harvest the Moon's natural resources to sustain human life.
- NASA's Michelle Thaller walks us through what it will take to sustain human life on the surface of the Moon.
- One way would be to run a very strong electrical current through water, separating it into hydrogen and oxygen. It's how astronauts on the International Space Station currently harvest oxygen to breathe.
- There's already evidence of ice at the Moon's poles, likely thanks to billions of years of asteroid and comet collisions. All we have to do is harvest it. People on the future Moon base could also use those ice repositories to make liquid rocket fuel.
