Medical Xpress / Upfront and personal: Scientists model human reasoning in the brain's prefrontal cortex
(Medical Xpress)—Located at the forward end of the brain's frontal lobe, the mammalian prefrontal cortex (PFC) is the seat of many of our most unique cognitive abilities – collectively referred to as executive function – ...
Phys.org / Proof of life: Reevaluating oldest known Archean trace fossil for indications of early biology
(Phys.org) —In the hunt for early life, geobiologists seek evidence of ancient microbes in the form of trace fossils – geological records of biological activity – embedded in lavas beneath the ocean floor. Filamentous titanite ...
Phys.org / From barrels to biology: Scientists develop cost-competitive bioderived polymers for a post-petroleum future
(Phys.org) —The advantages of sustainable, biodegradable, carbon-neutral and bioderived renewable polymers – that is, synthetic polymers based on biomolecules produced by living organisms – are reflected in the extent of ...
Phys.org / Eavesdroppers begone: New quantum key distribution technique is impervious to noise
(Phys.org) —Cryptography – the art and science of providing secure communications – typically employs three methods to authenticate users and prevent data theft: secret key (symmetric) cryptography, which uses a single key ...
Phys.org / A matter of matter: Demonstrating destructive quantum interference using Bose-Einstein condensates
(Phys.org) —When C. K. Hong, Z. Y. Ou and Leonard Mandel demonstrated destructive quantum interference between pairs of indistinguishable bosons in their 1987 paper1, they did so with massless photons. Their protocol – christened ...
Phys.org / Heads or tails: Experimental quantum coin flipping cryptography performs better than classical protocols
(Phys.org) —Cryptography – the practice and study of techniques for secure communication in the presence of third parties, referred to as adversaries – has a long and varied history. In ancient Greece, for example, the Spartan ...
Medical Xpress / Staying focused: Cortico-thalamic pathway filters relevant sensory cues from perceptual input
(Medical Xpress)—On the one hand, the nervous has limited computational capability – but at the same time, the sensory environment contains an immense amount of information. In this demanding situation, the brain somehow ...
Medical Xpress / Good vibrations: Cortical oscillations modulated by sensory, environmental, internal, and volitional inputs
(Medical Xpress)—Cortical information is carried by axonal spike timing, which is also a key factor in synaptic plasticity. Spike timing, in turn, can be synchronized by cortical oscillations, thereby regulating cortical ...
Phys.org / Room to move: Tissue growth controlled by cell cycle response to spatial and mechanical constraints
(Phys.org) —One of the most important factors in tissue formation is the control of cell proliferation. While the fact that cells undergo a range of spatial and mechanical constraints, the ways the resulting mechanical feedback ...
Phys.org / Bright lights, small crystals: Scientists use nanoparticles to capture images of single molecules
When imaging at the single-molecule level, small irregularities known as heterogeneities become apparent – features that are lost in higher-scale, so-called ensemble imaging. At the same time, it has until recently been challenging ...
Medical Xpress / What you see is where you go: Fruit fly visual interneurons may compute temporal integration of visual motion
(Medical Xpress)—The fruit fly Drosophila melanogaster is a model organism (a non-human species that is extensively studied to understand particular biological phenomena) studied in a wide range of laboratory experiments ...
