Wed, 26 Oct 2016 14:00:06 EDTAdding warmth predicted in climate-change models destabilized forest ant communities east of the Appalachian Mountains, a possible harbinger of disruption to the broader ecosystem, researchers, led by a Case Western Reserve University biologist, have found.
Wed, 26 Oct 2016 14:00:05 EDTSea star wasting disease has devastated intertidal populations of these animals on the West coast from Mexico to Alaska. But what about sea stars that live below the low tide line, mostly out of sight? An analysis of data collected by divers in the Salish Sea shows severe impacts on some species, especially the sunflower sea star, Pycnopodia helianthoides.
Wed, 26 Oct 2016 14:00:01 EDTIn the world of big data, there are limitations on how to store large volumes of information. Typical home-computer hard disk drives consume a lot of power and are limited to a few terabytes per drive. Optical storage media like DVD and Blu-ray are energy efficient and cheap, but storage densities are very low due to the planar nature of the discs and the ever-daunting optical diffraction limit. However, researchers have made inroads into developing a 3-D diamond chip that could store vastly more data than current technologies.

Wed, 26 Oct 2016 13:22:21 EDTAcross the nation, U.S. fishermen landed 9.7 billion pounds of fish and shellfish valued at $5.2 billion, a volume and value similar to recent years. The highest value U.S. commercial species were lobster ($679.2 million), crab ($678.7 million), shrimp ($488.4 million), salmon ($460.2 million), and Alaska (walleye) pollock ($441.7 million). By volume, the nation's largest commercial fishery remains Alaska (walleye) pollock, which had landings of 3.3 billion pounds (up 4 percent from last year), trailed by Atlantic and Gulf menhaden, which accounted for 1.6 billion pounds (up 29 percent).
Wed, 26 Oct 2016 13:09:16 EDTFor many of us, the term "doubly magic" may evoke images of Penn & Teller. However, for nuclear physicists, it describes atomic nuclei that have greater stability than their neighbors thanks to having shells that are fully occupied by both protons and neutrons. Theoretical physicists at the Department of Energy's Oak Ridge National Laboratory recently used Titan, America's most powerful supercomputer, to compute the nuclear structure of nickel-78, consisting of 28 protons and 50 neutrons, and found that this neutron-rich nucleus is indeed doubly magic. The results, published in the journal Physical Review Letters, may improve understanding of the origin, organization and interactions of stable matter.

Wed, 26 Oct 2016 13:00:11 EDTA new study, published this week in mSphere, provides evidence that Aspergillus fumigatus, a significant opportunistic fungal threat to human health, grows and behaves similarly on the International Space Station compared with earth. The study provides important information that can help with space exploration. As the durations of manned space missions increase, it is vitally important to understand the long-term consequences of microbial exposure on human health in closed human habitats.
Wed, 26 Oct 2016 13:00:10 EDTOn October 26th Nature will publish a study that overturns the decades-old textbook model of action for a protein that is central for many processes in living cells. Researchers at the FOM Institute AMOLF and the University of Heidelberg show that the protein Hsp70 can mechanically stabilize folded proteins using a moveable lid, and thus protect them against stress and damage. This insight into how proteins help each other, offers a new perspective on diverse cellular functions and can ultimately lead to a better understanding of diseases like cancer and Parkinson's, in which failing protein systems are central.
Wed, 26 Oct 2016 13:00:01 EDTFor the first time, astronomers have seen a dusty disk of material around a young star fragmenting into a multiple-star system. Scientists had suspected such a process, caused by gravitational instability, was at work, but new observations with the Atacama Large Millimeter/submillimeter Array (ALMA) and the Karl G. Jansky Very Large Array (VLA) revealed the process in action.

Wed, 26 Oct 2016 12:04:19 EDTFifteen years ago, in an effort to improve teacher benefits, St. Louis Public Schools enacted a change to the defined-benefit pension plan that resulted in an immediate and dramatic increase in the incentives to remain teaching in St. Louis. Similar enhancements also occurred across the country. Now, a study from Cory Koedel, associate professor of economics and public policy in the College of Arts and Science and the Truman School of Public Affairs at the University of Missouri, found that pension enhancements may not be a cost-effective or productive way to increase employee retention. Koedel says that these findings will be useful for informing pension policy as states attempt to address pension shortfalls while retaining effective teachers.

Wed, 26 Oct 2016 11:25:57 EDTMany astronauts play instruments, and some have even made music in space. Few have danced in space, though, perhaps because crew members find it difficult to tap their toes when weightless. Or it could be that spending time in space throws off their rhythm - at least their circadian rhythm.
Wed, 26 Oct 2016 11:24:36 EDTWe have it easier than cows.
