Why teenagers take risks

Teenagers take risks because they are not effective at predicting the consequences of their actions – or they act on the spur of the moment because they don’t plan ahead. Right? No, not really.

New research by Beatriz Luna, professor of psychiatry and paediatrics at the University of Pittsburgh in America says that the risky behaviour of teenagers is due to large doses of dopamine coursing through their brains.

Teenagers take risks because of temporary brain circuits that reward them with large doses of dopamine, a hormone that makes people happy. Dopamine is a neurtransmitter that helps control the brain’s reward and pleasure sections. It enables people to see a reward and initiatie action to receive it. It also regulates emotional responses. Psychologists maintain that low dopamine activity in the brain may make people prone to addictions. And the presence of a specific kind of dopamine receptor is associated with sensation-seeking people, more commonly known as risk-takers.

The brains of teenagers are therefore attuned to taking risks as part of growing up – to test the boundaries and to receive levels of happy hormones. These risks could include fighting, undertaking extreme sports, or experimenting with drugs and alcohol.

Luna says teenagers take risks because, as they gain independence, they gain control plus an extra reward, such as instant gratification, when they take risks. So teenagers take risks due to the dopamine rewards after risk-taking behaviour, which leads to further risky behaviour.

2016 update on Rike Park, Tbilisi: from construction to busy park

From a flat patch of uninteresting dirt, Rike Park in Tbilisi, Georgia, has transformed in four years (from 2014-2016) into a busy park full of trees, flower beds, sculptures, fountains, and events. Rike (Rikhe) Park is on the left bank of the Mt’k’vari River (the Kura River) near the Old City of Tbilisi. The Peace Bridge links the right bank to Rike Park. Rike Park is below the hillside Presidential Palace and, via cable car, it is the starting point for the ride to Sololaki Ridge (with the Narikala Fortress and the Mother of Georgia statue). The glass box-shaped cable car terminus was opened on 23 June 2012, and since then the park has continually developed into a ‘people’s park’ where people can walk around, eat at the nearby restaurants, sit next to the statue of American president Ronald Reagan, climb the steps to Avlabari district, and access the sights of Meidan Square, the Peace Bridge, the Metekhi Church, the Old City, the waterfall, the sulphur baths, and 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.
