Examining Smilodon"s saber teeth
A team of researchers led by Narimane Chatar, a doctoral student at the EDDyLab of the University of Liège (Belgium), has tested the biting efficiency of Smilodon, an extinct genus of carnivore close to the extant felines. Using high-precision 3D sc.....»»
Examining the three dimensions of a flower
To better understand the evolution of flowers, a research team in biology from Université de Montréal, the Montreal Botanical Garden and McGill University have succeeded in using photogrammetry to quickly and precisely build, in three dimensions, a.....»»
Examining the promotion of Arabidopsis immune responses by a rhizosphere fungus
Plants can form diverse intimate relationships with beneficial mycorrhizal, endophytic and or rhizosphere fungi for nutrient trades. It is now known that plants can transfer carbon sources like fatty acids to fungi while the fungi mediate the supply.....»»
The ingenious way that marsh grass shrimp reduce drag while swimming
The shrimp flexes its legs on the recovery stroke and keeps them close together. This is how a free-swimming marsh grass shrimp (Palaemonetes vulgaris) moves forward using metachronal locomotion to reduce drag. Marsh grass shrimp (P.....»»

The shrimp flexes its legs on the recovery stroke and keeps them close together. This is how a free-swimming marsh grass shrimp (Palaemonetes vulgaris) moves forward using metachronal locomotion to reduce drag. Marsh grass shrimp (P.....»»
Examining the limits of nonlocal wide-field-of-view metalenses
Metalenses, compact lenses made with metasurfaces, have the potential to enable thinner, lighter, cheaper, and better imaging systems for a wide range of applications where miniaturization is critical (e.g., for mobile devices, medical imaging, and a.....»»
Researchers demonstrate light-induced locomotion in a nonliquid environment and report a new type of liquid-like motion
Motion is everywhere in living systems and is necessary for mechanical functions in artificial systems, such as robots and machines. Functional mechanical structures that can change volume and shape in response to external stimuli (such as light, hea.....»»
