These materials have unique properties that promise better integration of optical communication with traditional silicon-based devices.
	Halloysite may be a promising natural nanomaterial Researchers have recently presented in Advanced Materials a broad scope of application of halloysite clay tubes.
	Ultrathin perovskite nanocrystals suitable for use in tunable and energy-efficient LEDs Perovskites have recently emerged as a most promising material for low-cost production of highly efficient solar cells. In particular, the so-called organic-inorganic metal halide perovskites are among the most exciting recent discoveries in the field of photovoltaics in. In less than five years, researchers have succeeded in increasing the energy-converting efficiency of perovskite-based solar cells from 4 to more than 20%. Indeed, in this respect, these relative newcomers have already overtaken many alternative photovoltaic materials, such as purely organic ones. Furthermore, perovskites are not only capable of absorbing light and converting it into electricity, they also display outstanding properties as light emitters.

Physics news

	Researchers observe phase transition thought impossible An ultrapure material taken to pressures greater than that in the depths of the ocean and chilled to temperatures colder than outer space has revealed an unexpected phase transition that crosses two different phase categories.
	Unraveling the complex, intertwined electron phases in a superconductor A team led by researchers from the U.S. Department of Energy's Brookhaven National Laboratory and Cornell University has characterized a key arrangement of electrons in a high-temperature superconductor, a material that can conduct electricity with almost no energy loss without being ultra-chilled. The material is a member of a family of copper-oxygen-based superconducting compounds-the cuprates-that are prime candidates for numerous potential high-impact applications, including extremely efficient electricity generation, storage, and transmission across the nation's power grid.
	Entanglement at heart of '2-for-1' fission in next-generation solar cells An international team of scientists have observed how a mysterious quantum phenomenon in organic molecules takes place in real time, which could aid in the development of highly efficient solar cells.
	Physicists uncover novel phase of matter A team of physicists led by Caltech's David Hsieh has discovered an unusual form of matter—not a conventional metal, insulator, or magnet, for example, but something entirely different. This phase, characterized by an unusual ordering of electrons, offers possibilities for new electronic device functionalities and could hold the solution to a long-standing mystery in condensed matter physics having to do with high-temperature superconductivity—the ability for some materials to conduct electricity without resistance, even at "high" temperatures approaching -100 degrees Celsius.

	Response to environmental change depends on individual variation in partnership between corals and algae New research reveals that some corals are more protective than others of their partner algae in harsh environmental conditions. This individual variation among corals could reflect a greater capacity than currently recognized to adapt to changing ocean conditions brought about by climate change. The study, led by marine biologists at Penn State University, will be published online October 26, 2015 in the open access journal Scientific Reports.
	If a major economy takes the lead, warming could be limited to 2 C, researchers say Though most countries around the globe agree that warming must be limited to 2 degrees Celsius to avoid the raft of climate risks, they clash about who should do what to reach this target. Hence the issue of allocating greenhouse-gas emissions reductions will be key for the outcome of the world climate summit COP21 in Paris. Scientists now found what amount of emissions reductions it takes for a major economy to lead out of the climate gridlock. They conclude that effectively limiting climate change is possible if a major economy acts as a forerunner, while other nations follow and, importantly, by doing so they do not have to agree on common criteria for fairness.

Astronomy & Space news

	Scientists predict that rocky planets formed from 'pebbles' Using a new process in planetary formation modeling, where planets grow from tiny bodies called "pebbles," Southwest Research Institute scientists can explain why Mars is so much smaller than Earth. This same process also explains the rapid formation of the gas giants Jupiter and Saturn, as reported earlier this year.
	X-ray emission from massive stars Massive young stars are known to emit strong X-rays. Unlike the X-ray emission from lower mass stars, however, which arises in stellar photospheres, the X-rays from massive stars are thought to result from powerful shocks. Several kinds of shocks can be responsible, produced either by very strong winds driven by the star's radiation, by the head-on collision between winds that have been magnetically channeled by the star's magnetic field, or by wind collisions in a binary stellar system in which each stars has a wind. Sorting out the mechanisms enables astronomers to identify the most active physical processes at work, and thereby decode additional information about the star's physical makeup and evolutionary status.
	Scientists predict space debris to enter earth's atmosphere around the Indian Ocean Millions of bits of space junk—leftover fragments from spacecraft and related debris—orbit Earth, and the majority of these will eventually fall into Earth's atmosphere and incinerate. Astronomers believe they have recently observed one of these pieces and, for the first time, can predict when and where it will enter the atmosphere. Such forecasts could allow scientists the opportunity to observe these events to better understand what happens when space debris—manmade or natural—comes in contact with the atmosphere and determine which objects might be hazardous to humans.

Chemistry news

	Tiny sponges behave in a counterintuitive way when adsorbing water (Phys.org)—When a kitchen sponge adsorbs water into its pores, it softens and expands. Now in a new study published in The Journal of Physical Chemistry Letters, scientists have discovered that, when microporous materials adsorb fluid, they initially soften but then stiffen as they adsorb more fluid. It's as if soaking your kitchen sponge in water eventually caused it to harden.

	New high-speed microscope images entire living organisms at high resolution A new microscope developed at the Howard Hughes Medical Institute's Janelia Research Campus is giving scientists a clearer, more comprehensive view of biological processes as they unfold in living animals. The microscope produces images of entire organisms, such as a zebrafish or fruit fly embryo, with enough resolution in all three dimensions that each cell appears as a distinct structure. What's more, it does so at speeds fast enough to watch cells move as a developing embryo takes shape and to monitor brain activity as it flashes through neuronal circuits.
	Male mosquitoes lured to traps by sounds of female wing-beats Like mariners lured on to the rocks by the siren songs of legend, male mosquitoes have been found to zero in on inexpensive traps that broadcast sound that is similar in frequency to the sound that is produced by the wing-beats of female mosquitoes—a discovery that may lead to better mosquito control in developing countries.
	Two mutations are better than one Two wrongs don't make a right, but in the case of genetic mutations, having two mutations in the same gene could be better than having either one individually. Recent research by biologists at San Diego State University found that two separate genetic modifications each greatly reduced the function of the myosin muscle protein in fruit flies, but flies with both mutations had nearly three-quarters of the protein function restored. The findings are important for researchers looking to better understand and treat heart muscle disease in humans.

	Loss of large land mammals could change landscapes forever Large land animals such as elephants, wildebeest and other big plant-eaters are worth preserving in part because their disappearance could have permanent effects on the plants and animals they coexist with, according to an analysis of past large-mammal extinctions in North and South America.
	Elephants boost tree losses in South Africa's largest savanna reserve Protected areas, such as nature reserves and national parks, play a crucial role in sheltering wildlife, such as African elephants, from hunting and habitat destruction. But it's important that conservation managers understand how the vegetation in these natural protected zones is affected by the population growth that is spurred by this animal safeguarding. To this end, new work from a team led by Carnegie's Greg Asner examined the effect elephants have on the woody plant life in Kruger National Park, the largest protected area in South Africa, and showed that elephants are one of the preserve's leading causes of fallen trees.
	'Hypercarnivores' kept massive ancient herbivores in check When the largest modern-day plant-eaters—elephants—are confined to too small an area, they devastate the vegetation. So 15,000 years ago, when the herbivores like the Columbian mammoth, mastodons and giant ground sloths were even larger, more numerous and more widely distributed, how did the landscape survive?
