A study carried out by researchers at the Universitat Autònoma de Barcelonashows that protecting natural spaces does not prevent invasion by foreign vegetation species. Montserrat Vilà and Jordi Pujadas, researchers at the CREAF, have published the study, the first to quantify the relationship between species invasions and human activity on a regional scale, in Biological Conservation.

The introduction of foreign species is a global phenomenon which has negative effects on the conservation o

A team of researchers at the Universitat Autònoma de Barcelona, co-ordinated by Professors Josep Egozcue and Cristina Templado, has shown for the first time that the older a man is, the more probable it is that his spermatozoa will present chromosome anomalies. This is the first time that a lineal relationship has been established with precision between these two factors. The conclusions of this study, published in the European Journal of Human Genetics, increase the importance of the father’s age in

Research chemists at the University of Warwick have devised and patented a new process called Living and Controlled Radical Polymerisation which can cheaply and easily grow designer polymers (plastics). They have already used the process to produce a wide range of designer polymer designs that are now being tested by major companies for use in applications as diverse as hairspray, anti-obesity drugs and inkjet printer ink.

Previously “designer-polymers” could only be synthesised by resorting

Four years ago, torrential rains battered the Southern US, mudslides struck in Peru – and the inhabitants of Canada`s west coast saved up to 30% on their winter heating bills. The cause? El Niño, a huge temperature shift in the Pacific Ocean which spawns climate changes globally. Today, using satellite Earth observation data, scientists are detecting the early warning signs of a new El Niño event and predicting that it will develop over the next 3 to 6 months, bringing climate changes to countries th

Two space probes lift the lid on Jupiter’s magnetosphere.
Even Stanley Kubrick couldn’t have directed it better. In the first days of 2001, two spacecraft, Cassini and Galileo, met at Jupiter 400 million kilometres from Earth, to study the mysterious forces emanating from the giant planet.

The first analysis of the data they sent back has now been unveiled 1-7 . It paints a dramatic picture of the planet’s invisible magnetosphere – looping magnetic fields, crackling radi

Linguists filter languages for sound before meaning.

Bilingual people switch off one language to avoid speaking double Dutch. By first sounding out words in their brain’s dictionary, they may stop one tongue from interfering with another.

Those fluent in two languages rarely mix them up. They switch between language filters that oust foreign words, Thomas Munte of Otto von Guericke University in Magdeburg, Germany, and his team suggest 1 .
