Phys.org / 'Goldilocks size' rhodium clusters advance reusable heterogeneous catalysts for hydroformylation

Recent research has demonstrated that a rhodium (Rh) cluster of an optimal, intermediate size—neither too small nor too large—exhibits the highest catalytic activity in hydroformylation reactions. Similar to the concept ...

Phys.org / Cuttlefish use polarized light to create a dramatic mating display invisible to humans

Many organisms leverage showy colors for attracting mates. Because color is a property of light (determined by its wavelength), it is easy for humans to see how these colors are used in animal courting rituals. Less obvious ...

Phys.org / From stellar engines to Dyson bubbles, alien megastructures could hold themselves together under the right conditions

New theoretical models have strengthened the case that immense, energy-harvesting structures orbiting their host stars could exist in principle in distant stellar systems. With the right engineering precautions, calculations ...

Phys.org / Protein 'dark energy' provides insight into form vs. function in structure

Astronomers use the term dark energy to refer to energy in the universe that is unaccounted for by ordinary matter but necessary to explain cosmology. Astronomy, however, isn't the only field with missing energy. Rice University ...

Phys.org / Milky Way is embedded in a 'large-scale sheet' of dark matter, which explains motions of nearby galaxies

Computer simulations carried out by astronomers from the University of Groningen in collaboration with researchers from Germany, France and Sweden show that most of the (dark) matter beyond the Local Group of galaxies (which ...

Medical Xpress / 16 years of brain scans reveal the cerebellum's crucial role in human language

The cerebellum, often called the little brain, plays a much bigger role in language processing than once believed. Located at the base of the brain, the cerebellum has long been thought to be mainly responsible for motor ...
