London’s urban heat island effect, which keeps night-time temperatures in the capital warmer than in surrounding rural areas, may have been underestimated by up to 45 per cent. The heat can pose serious health risks, particularly for the elderly and very young.

A study that involved fitting bumblebees with tiny radio frequency tags found long-term exposure to a neonicotinoid pesticide hampers bees’ ability to forage for pollen. The research by Nigel Raine, a professor at the University of Guelph, and Richard Gill of Imperial College, London, shows how long-term pesticide exposure affects individual bees’ day-to-day behaviour, including…

Have you ever wondered if the cute light rail systems some large cities are installing actually get people out of their cars and have a positive environmental impact? For the first time, researchers have shown that installing light rail on an existing traffic corridor not only gets people out of their cars, but reduces congestion…

Super Moons are full moons that are extra, well, super! They are super because they appear larger in the evening sky than your run of the mill full moon. In June of last year, a full Moon made headlines. The news media called it a “supermoon” because it was 14% bigger and 30% brighter than…

Astrobiologists from the United States and Germany recorded the highest known level of solar UV radiation to reach Earth’s surface. This was around 10 years ago. On December 29, 2003, the UV Index (UVI) peaked, reaching the blistering number of 43.3 over the Andes Mountains in Bolivia. To put this in context, a beachgoer in…

The Amazon is the largest tropical forest on the planet, covering about 6.5 million square kilometers, although much has been lost (around 18-20 percent) in recent decades. The great forest also, very likely, contains the highest biodiversity of species on land; for example a single hectare in Yasuni National Park contains more tree species than…

Extreme weather events and other natural disasters claimed the lives of more than 2,700 people and caused around US $42 billion in damage worldwide in the first half of 2014, but this was well below the first half of last year and a 10-year average, according to new research from reinsurer Munich Re. However, the…

A new Yale-led study quantifies for the first time the primary causes of the “urban heat island” (UHI) effect, a common phenomenon that makes the world’s urban areas significantly warmer than surrounding countryside and may increase health risks for city residents. In an analysis of 65 cities across North America, researchers found that variation in…

Becoming an Astronaut is a big deal! Men and women selected to go into space are very carefully chosen. They go through rigorous medical evaluations to make sure they are healthy and that their bodies can withstand the forces of liftoff and re-entry. And they go through months and months of training to prepare them…

Some of the world’s most endangered forests may soon benefit from better protection, thanks to discarded treasures from the consumer society – mobile phones. A Californian technology startup, Rainforest Connection (RFCx), has developed a tool – made from recycled smartphones – that it says will pilot new ways to monitor and stop illegal logging and…
