“Biological diversity is a widely under-appreciated resource that is essential for human existence and has a crucial role to play in sustainable development and in the eradication of poverty. Biodiversity provides millions of people with livelihoods, helps to ensure food security, and is a rich source of both traditional medicines and modern pharmaceuticals.” That is how UN Secretary-General Kofi Annan defined biodiversity at the International Day for Biological Diversity in 2003.
Humans intimately depend on biological capital, and without it, it would have been impossible to reach the level of prosperity that we currently enjoy. Plants have graced us with food, medicine,wood, and energy, but during the last century, human pressures and rapid industrial development have severely affected the natural heritage. The extinction of new species brings the irreversible loss of unique plants directly related to human development and prosperity.
Each plant has a genetic warehouse and biochemical information; the extinction of just one species can cause the loss of very important information for the human’s well-being. In addition biodiversity as the variety of all forms of life on earth is required for the recycling of essential elements such as oxygen, to reduce pollution and acts as a buffer against variations in weather and climate.

New Project SNAPSTER: Novel luminescent materials by encapsulating phosphorescent metal clusters with organic liquid crystals
Nowadays energy conversion in lighting and optoelectronic devices requires the use of rare earth oxides.
Scientists have discovered the first synthetic material that becomes thicker - at the molecular level - as it is stretched.
Researchers led by Dr Devesh Mistry from the University of Leeds discovered a new non-porous material that has unique and inherent "auxetic" stretching...
Scientists from the Theory Department of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science (CFEL) in Hamburg have shown through theoretical calculations and computer simulations that the force between electrons and lattice distortions in an atomically thin two-dimensional superconductor can be controlled with virtual photons. This could aid the development of new superconductors for energy-saving devices and many other technical applications.
The vacuum is not empty. It may sound like magic to laypeople but it has occupied physicists since the birth of quantum mechanics.
