Air pollution reduces the life expectancy of northern Chinese

China supplied its northern citizens with free coal for heating and cooking. That free-coal policy is now having an adverse effect: their life expectancy is being shortened.

The free-coal policy was in effect north of the Huai River between 1950 and 1980, reports the BBC and the Financial Times (July 9, 2013). Five hundred million people live in the region. A 2013 study conducted by Chinese, American, and Israeli researchers on air pollution and life expectancy reveals that the northern residents have reduced their life expectancy by 5.5 years with higher rates of heart and lung disease than the rest of China’s population. The air pollution from burning coal in the area north of the Huai River was 55% higher than the air quality in the south.

Researchers studied the pollution levels and deaths in 90 cities in the north of China and in the south between 1981 and 2000. The researchers focused on the total suspended particles (TSP) in the air, such as soot and smoke. They also analysed mortality statistics from 1991 to 2000 and found evidence of shorter life expectancy in the areas that were previous under the free-coal policy. The study published in the Proceedings of the National Academy of Sciences indicated that there was an increase in the number of incidences of cardio-respiratory deaths.

Therefore while the provision of coal was aimed at keeping people warm and reducing the number of winter related deaths from the cold weather and influenza, it was counterproductive. The free-coal policy has had disasterous consequences for the health of citizens.

Apes go to the movies - and remember the scenes

Apes remember major events in movies, even after a single viewing. That’s the findings of primate research in Japan (New Scientist, September 17, 2015). Researchers at the Kyoto University in Japan conducted experiments with two species of apes – chimpanzees and bonobo primates – to test their memory and recall. Instead of using food to test memory, they used films. The researchers made two short movies to show to the apes. Fumihiro Kano and his colleague, Satoshi Hirata, starred in the films with another person dressed as an ape. They wanted to have strong dramatic scenes to see if the apes remembered them. In the first 30-second movie the character ape bursts through a door on the right hand side (there is also a door on the left hand side) and attacks the two researchers (characters) 18 seconds after the start. After 24 seconds a human character choses one of two weapons next to each other and launched a revenge attack on the ape. In the second 30-second movie t...

The acacia thorn trees of Kenya

There are nearly 800 species of acacia trees in the world, and most don’t have thorns. The famous "whistling thorn tree" and the Umbrella Thorn tree of Kenya are species of acacia that do have thorns, or spines. Giraffes and other herbivores normally eat thorny acacia foliage, but leave the whistling thorn alone. Usually spines are no deterrent to giraffes. Their long tongues are adapted to strip the leaves from the branches despite the thorns. The thorny acacia like dry and hot conditions. The thorns typically occur in pairs and are 5-8 centimetres (2-3 inches) long. Spines can be straight or curved depending on the species.
