New study refines biological evolution model
Models for the evolution of life are now being developed to try and clarify the long term dynamics of an evolving system of species. Specifically, a recent model proposed by Petri Kärenlampi from the University of Eastern Finland in Joensuu accounts for species interactions with various degrees of symmetry, connectivity, and species abundance. This is an improvement on previous, simpler models, which apply random fitness levels to species. The findings published in the European Physical Journal E demonstrate that the resulting replicator ecosystems do not appear to be a self-organised critical model, unlike the so-called Bak Sneppen model, a reference in the field. The reasons for this discrepancy are not yet known.

Fiber optic light pipes in the retina do much more than simple image transfer
(Phys.org) —Having the photoreceptors at the back of the retina is not a design constraint, it is a design feature. The idea that the vertebrate eye, like a traditional front-illuminated camera, might have been improved somehow if it had only been able to orient its wiring behind the photoreceptor layer, like a cephalopod, is folly. Indeed in simply engineered systems, like CMOS or CCD image sensors, a back-illuminated design manufactured by flipping the silicon wafer and thinning it so that light hits the photocathode without having to navigate the wiring layer can improve photon capture across a wide wavelength band. But real eyes are much more crafty than that.

Production phase for LSST camera sensors nears
(Phys.org) —A single sensor for the world's largest digital camera detected light making its way through wind, air turbulence, and Earth's atmosphere, successfully converting the light into a glimpse of the galactic wonders that this delicate instrument will eventually capture as it scans the night sky. When installed in the camera of the Large Synoptic Survey Telescope (LSST), these sensors will convert light captured from distant galaxies into digital information that will provide unprecedented insight into our understanding of the universe.

Highly charged ions: Multiply-ionized atoms for clocks, qubits, and constants
The world is mostly neutral. That is, most of the atoms in our environment are electrically neutral. The number of electrons in the outer parts of atoms equals the number of protons at the centers of atoms. As one or more electrons are plucked away from the atoms, the remaining electrons feel a much stronger positive pull from the nucleus. This enhanced pull, causing the atoms to shrink in size, ensures that those electrons are less vulnerable to the distractions of their environment, making them potentially valuable for next-generation atomic clocks, for quantum information schemes (where the loss of quantum coherence in qubits is a paramount danger), and for experiments trying to detect slight variations in the fine structure constant, the parameter that sets the overall strength of the electromagnetic force.

Chemists eye improved thin films with metal substitution
The yield so far is small, but chemists have developed a low-energy, solution-based mineral substitution process to make a precursor to transparent thin films that could find use in electronics and alternative energy devices.

Carbyne morphs when stretched: Calculations show carbon-atom chain would go metal to semiconductor
Applying just the right amount of tension to a chain of carbon atoms can turn it from a metallic conductor to an insulator. The research has implications for mechanically activated nanoscale electronics and optics.
