Nitrogen till the root
Nitrogen is an essential element for life, but since its availability is limited it must be recycled. The most important compartment on the planet where it accumulates is the atmosphere (N2). Hence, special bacteria introduce it into the biosphere through a process called fixation. Once there, it is transferred through the food chain from vegetables […]
Climate change, critical level
Global warming has not stopped since the industrial revolution and in the Quèquicom we are also witnesses. In 2006 we dedicated a report to climate change. In 2019, thirteen years later, we made an update. We will see how has evolved the CO2 in the atmosphere, the temperature of the sea in Estartit, the fish […]
A nursery of scientists
The center Món Natura Pirineus, in Les Planes de Son, is a nursery for young scientists. Since 2007, the La Pedrera Foundation organizes the Youth and Science stays. For two weeks students from all over Catalonia receive theory classes, practice in the laboratory and field work in the areas of biology or astronomy. To get […]
Laia, a branch in human evolution
The evolution up to Homo sapiens is a puzzle of many pieces that is intertwined in the past and we still have much to discover. In 2011, at the Can Mata dump, at Hostalets de Pierola, a piece of this puzzle was found: the fossil remains of a primate distant relative of humans. The specimen was […]
Organic farming
Organic farming reverses the conventional agriculture. It uses invertebrates to combat pests, take profit of weeds and take care of all the underground ecosystem instead of seeing only as an inert support for the plants.
Living in the Pyrenees
We will see some of the animals that lived in the Pyrenees and some of those still living. We will see the marmots of the alpine meadows, the boreal owl of the mountain pine forests, and the trout. Also we will understand how glaciation have shaped the look of this range.
Bacteria: from our intestine to Mars
Go to Mars will be an impossible mission if bacteria can not be used to produce the food needed by the astronauts, and to recycle detritus. In addition, each of the astronauts will take 2 kilos of bacteria in his digestive, the intestinal flora that any human needs to survive. We fly from intestinal Crohn’s […]
