A group of Canadian and international researchers and graduate students supporting the University’s Enviro-Net project to monitor climate change are now using IBM’s InfoSphere Streams software to quickly ingest, correlate and analyze data as it arrives from more than 500 sensors implanted in some of the world’s most remote – and vulnerable – ecosystems.
Plants are under permanent attack by a multitude of pathogens. To win the battle against fungi, bacteria, viruses and other pathogens, they have developed a complex and effective immune system. And just as in humans, this can also overshoot its target when some of the plant’s own proteins are mistakenly identified as foreign. Such autoimmune reactions can lead to tissue defects and growth arrest, and is particularly apparent in hybrids, where two divergent immune systems meet. Scientists from the Max Planck Institute for Developmental Biology in Tübingen, Germany, have now pinpointed the most common culprits for autoimmunity. Surprisingly, these are components of the immune system itself, which are mistakenly recognized by other immune receptors as intruders.
(Phys.org) —Scientists have argued for half a century about the existence of a form of diamond called lonsdaleite, which is associated with impacts by meteorites and asteroids. A group of scientists based mostly at Arizona State University now show that what has been called lonsdaleite is in fact a structurally disordered form of ordinary diamond.

Despite the fact that 81% of Canadians accept that temperature on Earth is increasing, Université de Montréal researchers have revealed that Canadians are generally misinformed about the science of climate change and are divided over the construction of new oil pipelines. The researchers’ study also found that 70% of Canadians perceive significant changes in weather where they live; 60% believe that weather in Canada has been getting more extreme; and 87% believe these changes are somewhat or very likely the consequence of a warming planet.

California’s approval of a $7.5 billion water bond has bolstered prospects for expanding reservoirs and groundwater storage, but the drought-prone state can effectively use no more than a 15 percent increase in surface water storage capacity because of lack of water to fill it, according to a new analysis released Nov. 20.
Scientists at Freie Universität Berlin, the University of Tubingen, and the Swiss Federal Institute of Technology in Zurich (ETH) provide a new 3D model of the protein Bax, a key regulator of cell death. When active, Bax forms pores in the membranes of mitochondria, causing the release of proteins from the intermembrane space into the cytoplasm. This in turn triggers a series of operations ending in cell death, which are often impaired in cancer cells.
What began as a project looking at the statistics of galaxy distributions found an underlying pattern that could help astronomers learn how the universe evolved
Thousands of authors’ works enter the public domain each year, but only a small number of them end up being widely available. So how to choose the ones taking center-stage? And how well can a machine-learning algorithm rank the most notable authors in the world? Allen B. Riddell at Dartmouth College set out to deliver some answers and he published his work, "Public Domain Rank: Identifying Notable Individuals with the Wisdom of the Crowd", on the ArXiv server.

Sure, it’s easy to say that research in microgravity is cool, but the European Space Agency’s (ESA) new electromagnetic levitator brings new meaning to the word. A new ESA facility aboard the International Space Station will serve as a furnace capable of levitating and heating metals up to 3,632 degrees Fahrenheit. Having such a facility in microgravity will allow scientists to observe fundamental physical processes that occur as liquid metals cool.

A potential path to identify imperfections and improve the quality of nanomaterials for use in next-generation solar cells has emerged from a collaboration of University of Oregon and industry researchers.
The control of certain childhood diseases is difficult, despite high vaccination coverage in many countries. One of the possible reasons for this is "imperfect vaccines," that is, vaccines that fail either due to "leakiness," lack of effectiveness on certain individuals in a population, or shorter duration of potency.
In many firms sales people spend as much time negotiating internally for lower prices as they do interacting with customers. A new study appearing in the November issue of Marketing Science, a publication of the Institute for Operations Research and the Management Sciences (INFORMS) finds that firms should allow their sales people to "waste" energy on internal negotiations. In fact, it says, firms should make the process wasteful on purpose.

A team of researchers from Caltech and the China Earthquake Administration has discovered an ancient, deep canyon buried along the Yarlung Tsangpo River in south Tibet, north of the eastern end of the Himalayas. The geologists say that the ancient canyon—thousands of feet deep in places—effectively rules out a popular model used to explain how the massive and picturesque gorges of the Himalayas became so steep, so fast.
China’s second great wall, a vast seawall covering more than half of the country’s mainland coastline, is a foundation for financial gain – and also a dyke holding a swelling rush of ecological woes.

Moreover, they managed to estimate the value of the magnetic moment of the planet HD 209458b.The group of scientists including one of the researchers of the Lomonosov State University published their article in the Science magazine.
During the development of mammals, the growth and organization of digits are orchestrated by Hox genes, which are activated very early in precise regions of the embryo. These "architect genes" are themselves regulated by a large piece of adjacent DNA. A study led by Denis Duboule, professor at the University of Geneva (UNIGE) and the Federal Institute of Technology in Lausanne (EPFL), Switzerland, reveals that this same DNA regulatory sequence also controls the architect genes during the development of the external genitals.
Swiss-based petrochemical firm Ineos launched plans Thursday to become the biggest player in Britain’s fracking sector with a $1.0-billion investment in the nation’s shale gas industry.

Enzymes carry out fundamental biological processes such as photosynthesis, nitrogen fixation and respiration, with the help of clusters of metal atoms as "active" sites. But scientists lack basic information about their function because the states thought to be critical to their chemical abilities cannot be experimentally observed.
How do galaxies like our Milky Way form, and just how do they evolve? Are galaxies affected by their surrounding environment? An international team of researchers, led by astronomers at the University of California, Riverside, proposes some answers.
Lookout, a security company, says it has been tracking malware that over the last two years has become more sophisticated as it hit millions of devices.
The bus drivers say they are inadequately paid and endure a stressful work schedule of split shifts.
Birds that are related, such as Darwin’s finches, but that vary in beak size and behavior specially evolved to their habitat are examples of a process called speciation. It has long been thought that dramatic changes in a landscape like the formation of the Andes Mountain range or the Amazon River is the main driver that initiates species to diverge. However, a recent study shows that speciation occurred much later than these dramatic geographical changes. Researchers from LSU’s Museum of Natural Science have found that time and a species’ ability to move play greater parts in the process of speciation. This research was published today in the print edition of Nature.
