 International Journal of Climatology{DISSERTATION} Green is cool, but US land changes generally are not Most land use changes occurring in the continental US result in raised regional surface temperatures, says a new study by scientists at the University of Maryland, Purdue University and the University of Colorado in Boulder. The study in the Royal Meteorological Society's International Journal of Climatology found that almost any change that makes land cover less "green" contributes to warming. A perhaps less intuitive finding is that conversion of any land to agricultural use results in cooling, even land that was previously forested.

Nature Nanotechnology{DISSERTATION} Breakthrough in industrial-scale nanotube processing Rice University scientists today unveiled a method for the industrial-scale manufacturing of pure carbon-nanotube fibers, a breakthrough that could lead to revolutionary advances in materials science, power distribution and nanoelectronics. The method builds upon tried-and-true processes the chemical industry has used for decades to produce polymer fibers. Findings from Rice's methodical, nine-year program are detailed in this week's Nature Nanotechnology.

Journal of Physical Chemistry C{DISSERTATION} Rice U. lab leads hunt for new zeolites In all the world, there are about 200 types of zeolite, a compound of silicon, aluminum and oxygen that gives civilization such things as laundry detergent, kitty litter and gasoline. But thanks to computations by Rice University professor Michael Deem and his colleagues, it appears there are -- or could be -- more types of zeolites than once thought.

Proceedings of the National Academy of Sciences{DISSERTATION} There's a speed limit to the pace of evolution, Penn biologists say A major conclusion of the work is that for some organisms, possibly including humans, continued evolution will not translate into ever-increasing fitness. Moreover, a population may accrue mutations at a constant rate –- a pattern long considered the hallmark of "neutral" or non-Darwinian evolution -– even when the mutations experience Darwinian selection.

{DISSERTATION} Robot fish could monitor water quality Nature inspires technology for an engineer and an ecologist teamed up at Michigan State University. They're developing robots that use advanced materials to swim like fish to probe underwater environments. Robotic fish -- perhaps schools of them operating autonomously for months -- could give researchers far more precise data on aquatic conditions, deepening our knowledge of critical water supplies and habitats.

Ecology{DISSERTATION} Wolves, moose and biodiversity: An unexpected connection Moose eat plants; wolves kill moose. What difference does this classic predator-prey interaction make to biodiversity? A large and unexpected one, say wildlife biologists from Michigan Technological University, reporting in the November 2009 issue of the journal Ecology.

Journal of Clinical Investigation{DISSERTATION} Disrupting male fertility The sexual function of male rodents can be impaired by in utero and/or neonatal exposure to external molecules such as DES that disrupt normal hormone functioning, giving rise to concerns that low-level exposure to such molecules might cause similar effects in humans. New research, to be published in the Journal of Clinical Investigation, has determined the molecular mechanism underlying many of the harmful effects of DES on the mouse testis.

Proceedings of the National Academy of Sciences{DISSERTATION} Snows of Kilimanjaro shrinking rapidly, and likely to be lost The remaining ice fields atop famed Mount Kilimanjaro in Tanzania could be gone within two decades and perhaps even sooner, based on the latest survey of the ice fields remaining on the mountain. The findings indicate a major cause of this ice loss is very likely to be the rise in global temperatures. Although changes in cloudiness and precipitation may also play a role, they appear less important, particularly in recent decades.

The 20-ton liquid xenon experiment is proposed as a major experiment for the Deep Underground Science and Engineering Laboratory, a national lab planned for the former Homestake Mine beneath the Black Hills of South Dakota.

Science{DISSERTATION} Inequality, 'silver spoon' effect found in ancient societies The so-called "silver spoon" effect -- in which wealth is passed down from one generation to another -- is well established in some of the world's most ancient economies, according to an international study coordinated by a UC Davis anthropologist. The study, to be reported in the Oct. 30 issue of Science, expands economists' conventional focus on material riches, and looks at various kinds of wealth, such as hunting success, food sharing partners, and kinship networks.

Science{DISSERTATION} A new wrinkle in ancient ocean chemistry A research team led by University of California, Riverside geoscientists has corroborated evidence that oxygen production began in Earth's oceans at least 100 million years before the Great Oxidation Event (GOE). The researchers analyzed 2.5 billion-year-old black shales, which revealed that episodes of hydrogen sulfide accumulation in the oxygen-free deep ocean occurred nearly 100 million years before the GOE. Scientists have long believed that the early ocean was characterized by high amounts of dissolved iron.

American Naturalist{DISSERTATION} Trees facilitate wildfires as a way to protect their habitat Fire is often thought of something that trees should be protected from, but a new study suggests that some trees may themselves contribute to the likelihood of wildfires in order to promote their own abundance at the expense of their competitors. The study, which appears in the December 2009 issue of the journal the American Naturalist, says that positive feedback loops between fire and trees associated with savannas can make fires more likely in these ecosystems.

New research from Indiana University details how the weapon is wielded -- and its influence muted -- in a rare study that catches this national pastime on video. The study appears in the Journal of Contemporary Ethnography.

2009 International Society for Music Information Retrieval Conference{DISSERTATION} Electrical engineers go head to head with Genius on music playlists Electrical engineers recently pitted Genius -- the music recommendation system in Apple's iTunes -- against two experimental music recommender systems. Genius appears to capture acoustic similarities among songs within the same playlist, the researchers found. The University of California, San Diego, electrical engineers also discovered that the music recommender they built from scratch can generate song playlists that human subjects thought were as good as those that Genius generates.
