Why dogs can teach humans about healthier ageing

Our pet dogs could help extend human lives beyond their documented effects on people’s wellbeing. Increasingly, studies are looking at how the domestic dog, Canis familiaris, is key to understanding cognition and processes involved in ageing – something that could improve both animal and human wellbeing. ‘In recent years, the dog has grown to be one of … Read more

In the Antarctic, a scientist recruits albatrosses to pinpoint illegal fishing boats

Albatross expert Dr Henri Weimerskirch, of the French National Centre for Scientific Research (CNRS), turned his favourite seabirds into spies two years ago by fixing them up with loggers that could detect the radar of illegal fishing vessels. The information from this project, known as OCEAN SENTINEL, has helped governments select which parts of the ocean … Read more

Four storeys high and made almost entirely of wood, the ZEB Lab building in Trondheim, Norway, had, even before it existed, sucked as much carbon from the atmosphere as it would probably produce in construction. Now, thanks to its arboreal origins, as well as to the sleek expanse of solar panels on its roof and … Read more

Unravelling the when, where and how of volcanic eruptions

There are about 1,500 potentially active volcanoes worldwide and about 50 eruptions occur each year. But it’s still difficult to predict when and how these eruptions will happen or how they’ll unfold. Now, new insight into the physical processes inside volcanoes are giving scientists a better understanding of their behaviour, which could help protect the 1 billion people … Read more

Buildings, tunnels and bridges could soon repair themselves

Stone and concrete structures with the ability to heal themselves in a similar way to living organisms when damaged could help to make buildings safer and last longer. Over time the weather, vibration, ground movements and general wear and tear can take their toll on the masonry and concrete used in buildings. But keeping buildings in … Read more
