Exploring for oil and extracting it from the Amazon region of northeastern Ecuador has boosted the countrys income over the last several decades, but it has also resulted in a "public health emergency" due to the negative effects on the local environment and on the health of persons who live in the petroleum-production areas. That is according to an English-language article published in the most recent (March 2004) issue of the "Revista Panamericana de Salud Pública/Pan American Journal of Public Health." The "Revista/Journal" is a monthly, peer-reviewed scientific journal. The "Revista/Journal" article summarizes and reviews the scientific research that has been done on the environmental and health consequences of oil development in Ecuador.
Since the 1970s more than two billion barrels of crude oil have been pumped from oil fields in the Ecuadorian Amazon. Petroleum has been the "engine" for Ecuadors economy, helping push per capita income from US$ 290 in 1972 to US$ 1200 in 2000. Oil now accounts for some 40% of the nations export earnings and of the national governments budget.
While boosting the Ecuadorian economy, oil production has also had serious consequences for the environment. For example, in just the period of 1972 through 1993, more than 30 billion gallons (114 billion liters) of toxic wastes and crude oil were discharged into the land and waterways of the Ecuadorian Amazon. This far exceeds the 10.8 million gallons (40.9 million liters) spilled in the "Exxon Valdez" tanker disaster in 1989 in Alaska, one of the largest sea oil spills that has ever occurred.

A newly developed laser technology has enabled physicists in the Laboratory for Attosecond Physics (jointly run by LMU Munich and the Max Planck Institute of Quantum Optics) to generate attosecond bursts of high-energy photons of unprecedented intensity. This has made it possible to observe the interaction of multiple photons in a single such pulse with electrons in the inner orbital shell of an atom.
In order to observe the ultrafast electron motion in the inner shells of atoms with short light pulses, the pulses must not only be ultrashort, but very...
A group of researchers led by Andrea Cavalleri at the Max Planck Institute for Structure and Dynamics of Matter (MPSD) in Hamburg has demonstrated a new method enabling precise measurements of the interatomic forces that hold crystalline solids together. The paper Probing the Interatomic Potential of Solids by Strong-Field Nonlinear Phononics, published online in Nature, explains how a terahertz-frequency laser pulse can drive very large deformations of the crystal.
By measuring the highly unusual atomic trajectories under extreme electromagnetic transients, the MPSD group could reconstruct how rigid the atomic bonds are...

For the first time, a team of researchers at the Max-Planck Institute (MPI) for Polymer Research in Mainz, Germany, has succeeded in making an integrated circuit (IC) from just a monolayer of a semiconducting polymer via a bottom-up, self-assembly approach.
In the self-assembly process, the semiconducting polymer arranges itself into an ordered monolayer in a transistor. The transistors are binary switches used...
