Our brain is a prediction machine that is always active
This is in line with a recent theory on how our brain works: it is a prediction machine, which continuously compares sensory information that we pick up (such as images, sounds and language) with internal predictions. "This theoretical idea is extremely popular in neuroscience, but the existing evidence for it is…

Humans can't endure temperatures and humidities as high as previously thought
Penn State researchers found that the maximum wet-bulb temperature humans can endure is lower than previously thought — about 31°C wet-bulb or 87°F at 100% humidity — even for young, healthy subjects. The temperature for older populations, who are more vulnerable to heat, is likely even lower.

How Intelligent Are Cats? (2004)
Cat owners often claim that cats are too intelligent to do the sort of tricks that dogs do willingly. Others believe cats are unintelligent because it's harder to train them to do tricks. In this article (on 2 pages) I aim to explain some of these differences and explore feline intelligence and the limitations on…

Hydroponics: Growing an appreciation for plants
I once heard a saying – “Don’t feel pity on plants because they can’t move. Feel pity on us, because we have to”. I really didn’t have an appreciation for what this meant until the COVID pandemic hit, which restricted my movement for a couple of years, and I decided to spend some of my new-found time at home learning…

Microbes that cause cavities can form superorganisms able to ‘crawl’
These multicellular, cross-kingdom assemblages were more resistant to antimicrobials and removal and caused more extensive tooth decay than their single-species equivalents, according to research led by School of Dental Medicine scientists.

Empirical Notes on Kissing
Before my first kiss, I scoured The Internet (Google Scholar + tracing blog posts back to their underlying studies - this was some time ago so I don’t still have the sources) for every valuable scrap of information available on the topic while trying to stray away from anything opinion-based. This is the result.

Decades of air pollution undermine the immune system
The diminished power of the immune system in older adults is usually blamed on the aging process. A new study shows that decades of inhaled particulates due to air pollution also take a toll.
