Lessons from Iraq: Urban marshes and city survival
Jennifer Pournelle is continuing to build the case that natural wetlands, rather than irrigated fields, are the fertile ground from which cities initially emerged in Mesopotamia. And her conclusions about the importance of wetlands to a sustainable urban environment – or, in fact, any environment – have particular resonance in southern Iraq. That area is both the site of her studies and the region where Saddam Hussein forcibly drained marshes to drive out the local populace after the first Gulf war.

The first evidence that a yellow supergiant became a supernova
A group of researchers led by Melina Bersten (Kavli IPMU) has presented evidence that the yellow supergiant (YSG) star found at the location of supernova SN 2011dh in the famous nearby galaxy M51 was indeed the SN progenitor, as well as produced a self-consistent model to explain how a star of such characteristics exploded. In their model, the exploding YSG star was a member of a close binary system. The authors further predict the detection of the companion star as a definitive test of their hypothesis. Their paper has been published in the September 20, 2012, issue of The Astrophysical Journal.

Webb Telescope's 'wormholes' in the clean room
(Phys.org)—This photo gives a "worms eye" view of a robot arm holding a surrogate or simulated mirror segment (black hexagonal shape) for NASA's James Webb Space Telescope. The arm is placing the surrogate into the test backplane structure in the clean room at NASA's Goddard Space Flight Center in Greenbelt, Md. The holes in the test backplane aren't wormholes, but the openings in the structure that will support the Webb telescope's primary mirror segments.

Study shows that organic aerosols aging caused by OH radicals
Atmospheric aerosol particles have a significant effect on climate. An international team of researchers has now discovered that a chemical process in the atmosphere called aging determines to a major extent the concentration and the characteristics of aerosol particles. To date, this aspect has not been accounted for in regional and global climate models. In the Muchachas [Multiple Chamber Aerosol Chemical Aging Experiments] project, the team has not only managed to demonstrate the effects of aging but has also been able to measure these. Their findings have been published in the specialist journal Proceedings of the National Academy of Sciences (PNAS).

(Phys.org)—NASA's Deep Impact spacecraft completed a firing of its onboard rocket motors earlier today. The maneuver began at 1 p.m. PDT (4 p.m. EDT), lasted 71 seconds, and changed its velocity by 4.5 mph (2 meters per second). The rocket burn was performed to keep the venerable comet hunter's options open for yet another exploration of a solar system small body, this time a possible future visit to a small near-Earth asteroid called 2002 GT.

Weather-making high-pressure systems predicted to intensify as a result of increasing greenhouse-gas concentrations
(Phys.org)—High-pressure systems over oceans, which largely determine the tracks of tropical cyclones and hydrological extremes in much of the northern hemisphere, are likely to intensify this century, according to a Duke University-led study published online this week in Nature Geoscience.

Researchers build better earthquake simulator
(Phys.org)—Traditional earthquake simulators have generally functioned by pressing two pieces of rock material together at high pressure until they reach a breaking point, resulting in something similar to the sticking and sliding of real earthquakes. The problem with this approach, of course, is that because of the difference in scale, it's not clear if the model can be used to accurately represent real events. For this reason, researchers from the University of Oklahoma and the U.S. Geological Survey tried a new approach, pressing a piece of granite against a rotating flywheel. As described in a paper published in the journal Science, the researchers discovered that the resulting energy densities compared closely with results from measurements of real earthquakes.

Astronomers discover a new black hole in our galaxy
(Phys.org)—NASA's Swift satellite recently detected a rising tide of high-energy X-rays from a source toward the center of our Milky Way galaxy. The outburst, produced by a rare X-ray nova, announced the presence of a previously unknown stellar-mass black hole.

When green turns toxic: Norwegians study Electric Vehicle life cycle
(Phys.org)—Questioning thoughts arise from a bracing study from Norway. The electric car might be a trade-in of an old set of pollution problems for a new set. Thanks but no thanks to a misguided cadre selling on the green revolution. Electric cars will eventually be one more pollutant source to campaign over. The study, "Comparative Environmental Life Cycle Assessment of Conventional and Electric Vehicles," appears in the Journal of Industrial Ecology. Researchers from the Norwegian University of Science and Technology declared in the study that "EVs exhibit the potential for significant increases in human toxicity, freshwater eco-toxicity, freshwater eutrophication, and metal depletion impacts, largely emanating from the vehicle supply chain."

Researchers establish link between dry eye disease and dehydration
Dry eye disease (DED) is a condition which can cause extreme discomfort and lead to eye damage.  While difficult to establish the full costs of this condition to healthcare and society in the UK, it is estimated that current prescription treatments such as eye drops cost the NHS £32 million per year (in England alone).  Because many individuals suffering from DED self-treat by buying over-the-counter medications (e.g. artificial tears) the true cost of DED is likely to be significantly higher. This new link suggests that ensuring DED sufferers are fully hydrated could alleviate DED symptoms.

(Medical Xpress)—A new study by scientists in the US has found that the opiate morphine and the stimulant cocaine act on the reward centers in the brain in different ways, contradicting previous theories that these types of drugs acted in the same way.

Of enzymes and aging: Tryptophan metabolism plays key role in aging and age-related neurological diseases
(Medical Xpress)—In the battle against aging and age-related neurological diseases such as Parkinson's and Alzheimer's, a key factor has long appeared to be the toxicity of proteins which tend to aggregate. Recently, scientists at University of Groningen, The Netherlands identified the protein-coding gene TDO2 that encodes for tryptophan 2,3-dioxygenase – the enzyme that degrades tryptophan and thereby reduces its levels – as a metabolic regulator of age-related protein toxicity and lifespan in the eukaryotic nematode Caenorhabditis elegans. The researchers also showed that the regulation of lifespan occurred through evolutionarily conserved genetic pathways. The study demonstrated that TDO2 depletion increases tryptophan levels, while feeding C. elegans with extra L-tryptophan also suppresses toxicity. The researchers conclude that their findings suggest that TDO2 regulates proteotoxicity through tryptophan.

How to restore native grasslands in the interior Pacific Northwest
Weed scientists in Oregon have found that the timing of herbicide application along with reseeding of native grasses offers the best recipe for restoring native grasslands while controlling invasive weeds. Grasslands are a valuable resource for ecosystems, providing soil conservation, food and fiber production, and wildlife habitat. When threatened by invading exotic species, the quality and quantity of forage for wildlife can be reduced, fire frequencies can be altered, soil moisture and nutrients can be depleted, and the costs of land management can increase.

Cellular accumulation of misfolded protein clumps may be a survival advantage rather than a liability, researchers find
Most proteins have a single 'correct' way to fold; typically, improperly folded proteins are promptly eliminated by cells. However, certain misfolded proteins have a tendency to aggregate in dense fibrous clumps known as amyloid plaques. In humans, this accumulation is often a pathological feature, as observed in Alzheimer's or Huntington's disease.

Scientists advance cutting edge of immunology through study of macrophages
(Phys.org)—Macrophages are heavy hitters of the immune system. Their name literally means "to eat large objects." They are critical members of the body's defense team, such as in the lungs where they ingest invading microorganisms and at wound sites where they rush in and secrete coagulation factors that help form scabs. Macrophages also scavenge the body to find, digest, and recycle cell debris such as worn out red blood cells.
