From bands to spots, the secrets of the leopard gecko"s skin
While the patterns and colors of lizards' skin are fascinating, the mechanisms behind them are largely unknown. A team from the University of Geneva (UNIGE) studied the leopard gecko, a popular lizard, to understand how the bands on the skin of juven.....»»
The geometry of life: Physicists determine what controls biofilm growth
From plaque sticking to teeth to scum on a pond, biofilms can be found nearly everywhere. These colonies of bacteria grow on implanted medical devices, our skin, contact lenses, and in our guts and lungs. They can be found in sewers and drainage syst.....»»

How a global collaboration is helping protect biodiversity
Ask a 10-year-old to name some extinct animals and they can usually rattle off ancient species such as the Tasmanian Tiger, Woolly Mammoth and Dodo. Some may even be able to tell you what the animals used to look like without searching online......»»
Unlocking the potential of anti-perovskites through a convenient one-step synthesis route
Although perovskites have attracted a lot of attention lately, anti-perovskites hold just as much potential as functional materials. Bearing a similar crystal structure to perovskites but with an inverted electrical configuration, anti-perovskites ex.....»»
Novel strategy proposed for selectively targeting G-quadruplex at specific genome loci
DNA G-quadruplexes (G4s) are a type of quadruple helix structure formed by a continuous guanine-rich DNA sequence. Although DNA G4s are thought to be involved in various biological processes, in many cases their causative effects are largely unclear.....»»
Investigations of the polysomatism of antigorite under pressure
Antigorite is a type of serpentine, which is the most abundant hydrated mineral on the Earth. It is widely believed that this mineral is the main carrier of water deep into the Earth in subducting oceanic plates. It has a wavy structure along the a-a.....»»
Researchers synthesize garnet-rich lunar rock to study moon"s mantle
Our present-day moon has an interior structure containing a central metallic core, overlain by a mantle comprised of minerals such as olivine and pyroxene (e.g. Ol+Px mantle) underneath a shell of crust. Such a picture of the moon's interior has been.....»»
