According to meteorologists, the year 2009 could be one of the hottest ever recorded.

Global temperature is expected to be 0.4 ° C above average known. So far the warmest year remains 1998. For Professor Phil Jones, director of the Climate Research Unit at the University of East Anglia: “The fact that 2009, like 2008, not exploded the temperature record does not mean that the warming climate ‘ is stopped. What is striking is the global warming recorded over the period 2001-2007, which presents an average temperature of 14.44 ° C …

According to a team of American researchers, global warming would be irreversible.
Indeed, they argue that efforts at this time by the whole world to fight against this phenomenon will not be effective until the year 3000. However, scientists believe that we must continue our efforts in order not to deteriorate the situation further. In their report, it is specified that the increase of temperature implies an expansion of the oceans. These climate changes are a consequence of gas injected by man into the atmosphere, which trap solar heat, thus helping …

Global warming is a real scourge, it is necessary to fight against it to minimize its impact on the environment.
Many proposals have been made in recent years to fight against this phenomenon. Various hypotheses are developed on climate change that we are to live: in fact, while some believe it is already irreversible, others argue that a collective movement for the environment can change things. In any case, one thing is certain: the consequences of global warming are already visible.

A team of scientists formed by researchers from around the world has discovered amazing particles in the dust of dead stars. They seem to be the remains of planets similar to Earth, allowing them to predict the eventual fate of our solar system.
Of the stars as big as the sun reached the end of life, swell up to become red giants. When they explode, they become white dwarfs, surrounded by a cloud of gas forming a planetary nebula.
Between 1 and 3% of these stars could have been extinguished up their …

A new tool to repair the human brain: nanotubes
Carbon nanotubes could be used to repair faulty brain connections.
The study shows that carbon nanotubes are in contact with neuronal cell membranes to create shortcuts that generate neuronal excitation. This observation raises the hope of using nanotubes to repair certain lesions affecting the nervous system.
