Iron instead of precious metals

https://www.mpg.de/5860285/iron_aluminium_catalyst

An iron-aluminium compound could replace a palladium-based catalyst for the catalytic semi-hydrogenation of acetylene to ethylene. Al13Fe4, identified by scientists working with J. Grin of the Max Planck Institute for Chemical Physics of Solids and R. Schlögl of the Fritz Haber Institute of the Max Planck Society in knowledge-based catalysis research, could reduce the cost of plastics, as the selective hydrogenation of acetylene is an important step in polyethylene production.
They plan to use this same procedure to search for catalysts for other reactions

The hemispheres are not equal

Although the brain is divided into two halves, it is not exactly a mirror image. Some functions are processed more on the left side, others more on the right. Scientists at the Max Planck Institute for Human Cognitive and Brain Sciences and Forschungszentrum Juelich, together with an international team of neuroscientists, have now discovered heritable underpinnings of brain asymmetry—and—how much we share with monkeys.
And finally, the brain: it is divided into two halves that are roughly the same size
