Temperate and dry January in the nation's capital but wet and cold in Sydney

While other capital cities across Australia have had sweltering January temperatures, Canberra—the nation’s capital—has been moderate. Perth, the capital of Western Australia, and Adelaide, the capital of South Australia, had 35C-40C temperatures for much of January.

The Bureau of Meteorology recorded a mild January for Canberra. Canberra’s daytime temperature ranged from 18.6 to 34.7C. There was no single day over 35C – it is usual to have 6 days on average with temperatures over 35C in January. The average was 27.4C, just half a degree below its historical average of 28C. Canberra’s night time temperature averaged 12.4C, below its historical average of 13.3C. Its coldest night was a mere 1.6C on January 12, which was the coldest January minimum in 56 years - since 1956.

Therefore there were few highs and few lows (with one extreme exception) in Canberra with January temperatures remaining moderate and mild. This was due to the lack of north-easterly winds bringing warm air from Central Australia. Instead, the wind was easterly, bringing cooler air than usual. It has also been a dry January. The average rainfall for January in Canberra is a mere 58.5mm, but it was even drier with only half the average rainfall at just 30mm.

Sydney, on the other hand, recorded its wettest January in 11 years and the coldest one in 12 years. Sydney recorded 139mm of rain last month, exceeding the long term average of 101mm. January also had 13 rainy days compared to the average of 12. The average minimum temperature for the month was 19.6C and the average maximum was 26.1C, also making it the coldest January in 12 years. The wet, mild start to the year follows Sydney's coldest December in 51 years, which puts Sydney on track to record one of its coldest summers in recent decades.

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.
