Late not great -- imperfect timekeeping places significant limit on quantum computers      (via sciencedaily.com)     Original source 

Quantum physicists show that imperfect timekeeping places a fundamental limit to quantum computers and their applications. The team claims that even tiny timing errors add up to place a significant impact on any large-scale algorithm, posing another problem that must eventually be solved if quantum computers are to fulfill the lofty aspirations that society has for them.

Wireless device makes magnetism appear in non-magnetic materials      (via sciencedaily.com)     Original source 

Researchers have succeeded in bringing wireless technology to the fundamental level of magnetic devices. The emergence and control of magnetic properties in cobalt nitride layers (initially non-magnetic) by voltage, without connecting the sample to electrical wiring, represents a paradigm shift that can facilitate the creation of magnetic nanorobots for biomedicine and computing systems where basic information management processes do not require wiring.

Evolutionary chance made this bat a specialist hunter      (via sciencedaily.com)     Original source 

It is generally believed that, for millions of years, bats and the insects they hunt at night have adapted to each other in an evolutionary arms race to become better at finding or avoiding each other. Now, a new study shows that this may not be the case at all.

Genetic methods enable the use of fossil lipids as biomarkers for oxygen-producing primordial bacteria      (via sciencedaily.com)     Original source 

Cyanobacteria are a key species in Earth's history, as they introduced atmospheric oxygen for the first time. The analysis of their evolution therefore provides important insights into the formation of modern aerobic ecosystems. For a long time, a certain type of fossil lipid, so-called 2-methylhopanes, was considered to be an important biomarker for Cyanobacteria in sediments, some of which are hundreds of millions of years old. However, this came into doubt when it turned out that not only Cyanobacteria but also Alphaproteobacteria are genetically capable of producing these lipids.

Conduction electrons drive giant, nonlinear elastic response in Sr2RuO4      (via sciencedaily.com)     Original source 

The hardness of a material normally is set by the strength of chemical bonds between electrons of neighboring atoms, not by freely flowing conduction electrons. Now a team of scientists has shown that current-carrying electrons can make the lattice much softer than usual in the material Sr2RuO4.

Finding the genes that help kingfishers dive without hurting their brains      (via sciencedaily.com)     Original source 

Scientists studied the genomes of 30 kingfisher species to try to identify the genes that allow kingfishers to dive headfirst into water without huring their brains. The researchers found that the diving birds have unusual mutations to the genes that produce tau: a protein that helps stabilize tiny structures in the brain, but which can build up in humans with traumatic brain injuries or Alzheimer's disease. The researchers suspect that these variations in the kingfishers' tau proteins might protect their brains when they dive.

How quantum light 'sees' quantum sound      (via sciencedaily.com)     Original source 

Researchers have proposed a new way of using quantum light to 'see' quantum sound. A new paper reveals the quantum-mechanical interplay between vibrations and particles of light, known as photons, in molecules. It is hoped that the discovery may help scientists better understand the interactions between light and matter on molecular scales. And it potentially paves the way for addressing fundamental questions about the importance of quantum effects in applications ranging from new quantum technologies to biological systems.
