Highly charged ions melt nano gold nuggets      (via sciencedaily.com)     Original source 

Shooting ions is very different from shooting a gun: By firing highly charged ions onto tiny gold structures, these structures can be modified in technologically interesting ways. Surprisingly, the key is not the force of impact, but the electric charge of the projectiles.

Epigenetic fingerprint as proof of origin for chicken, shrimp and salmon      (via sciencedaily.com) 

Free-range organic chicken or factory farming? Scientists have developed a new detection method that can reveal such differences in husbandry. The so-called epigenetic method is based on the analysis of the characteristic patterns of chemical markers on the genome of the animals.

Nanophysics: The right twist      (via sciencedaily.com) 

Stacked layers of ultrathin semiconductor materials feature phenomena that can be exploited for novel applications. Physicists have studied effects that emerge by giving two layers a slight twist.

Rare beetle, rediscovered after 55 years, named in honor of Jerry Brown      (via sciencedaily.com) 

While sampling for insects on former California Gov. Jerry Brown's ranch, a University of California, Berkeley, entomologist collected a rare species of beetle that had never been named or described -- and which, according to records, had not been observed by scientists in over 55 years. The new species will be named Bembidion brownorum, in honor of Jerry Brown and his wife, Anne Brown.

New type of entanglement lets scientists 'see' inside nuclei      (via sciencedaily.com) 

Nuclear physicists have found a new way to see inside nuclei by tracking interactions between particles of light and gluons. The method relies on harnessing a new type of quantum interference between two dissimilar particles. Tracking how these entangled particles emerge from the interactions lets scientists map out the arrangement of gluons. This approach is unusual for making use of entanglement between dissimilar particles -- something rare in quantum studies.

Graphene grows -- and we can see it      (via sciencedaily.com) 

Graphene is the strongest of all materials. On top of that, it is exceptionally good at conducting heat and electrical currents, making it one of the most special and versatile materials we know. For all these reasons, the discovery of graphene was awarded the Nobel Prize in Physics in 2010. Yet, many properties of the material and its cousins are still poorly understood -- for the simple reason that the atoms they are made up of are very difficult to observe.

Climate change threatens global fisheries      (via sciencedaily.com) 

The diet quality of fish across large parts of the world's oceans could decline by up to 10 per cent as climate change impacts an integral part of marine food chains, a major study has found.

New microchip links two Nobel Prize-winning techniques      (via sciencedaily.com) 

Physicists have built a new technology on a microchip by combining two Nobel Prize-winning techniques. This microchip could measure distances in materials at high precision, for example underwater or for medical imaging. Because the technology uses sound vibrations instead of light, it is useful for high-precision position measurements in opaque materials. There's no need for complex feedback loops or for tuning certain parameters to get it to operate properly. This makes it a very simple and low-power technology, that is much easier to miniaturize on a microchip. What makes it special is that it doesn't need any precision hardware and is therefore easy to produce. It only requires inserting a laser, and nothing else. The instrument could lead to new techniques to monitor the Earth's climate and human health.

Turn off porch light to aid caterpillars -- and safeguard backyard ecosystems      (via sciencedaily.com) 

Moderate levels of artificial light at night -- like the fixture illuminating your backyard -- bring more caterpillar predators and reduce the chance that these lepidoptera larvae grow up to become moths and serve as food for larger prey.
