In commemoration of NASA's Hubble Space Telescope completing its 100,000th orbit in its 18th year of exploration and discovery, scientists at the Space Telescope Science Institute in Baltimore, Md., have aimed Hubble to take a snapshot of a dazzling region of celestial birth and renewal. Hubble peered into a small portion of the nebula near the star cluster NGC 2074 (upper, left). The region is a firestorm of raw stellar creation, perhaps triggered by a nearby supernova explosion. It lies about 170,000 light-years away near the Tarantula nebula, one of the most active star-forming regions in our Local Group of galaxies. The three-dimensional-looking image reveals dramatic ridges and valleys of dust, serpent-head "pillars of creation," and gaseous filaments glowing fiercely under torrential ultraviolet radiation. The region is on the edge of a dark molecular cloud that is an incubator for the birth of new stars. The high-energy radiation blazing out from clusters of hot young stars already born in NGC 2074 is sculpting the wall of the nebula by slowly eroding it away. Another young cluster may be hidden beneath a circle of brilliant blue gas at center, bottom. In this approximately 100-light-year-wide fantasy-like landscape, dark towers of dust rise above a glowing wall of gases on the surface of the molecular cloud. The seahorse-shaped pillar at lower, right is approximately 20 light-years long, roughly four times the distance between our Sun and the nearest star, Alpha Centauri. The region is in the Large Magellanic Cloud (LMC), a satellite of our Milky Way galaxy. It is a fascinating laboratory for observing star-formation regions and their evolution. Dwarf galaxies like the LMC are considered to be the primitive building blocks of larger galaxies. This representative color image was taken on August 10, 2008, with Hubble's Wide Field Planetary Camera 2. Red shows emission from sulfur atoms, green from glowing hydrogen, and blue from glowing oxygen. Source: NASA.

Water, water everywhere: How UV irradiation reversibly switches graphene between hydrophobic and hydrophilic states

more »

(Phys.org) —Scientists have long observed that the wettability of graphene – an essentially two-dimensional crystalline allotrope of carbon that it interacts oddly with light and with other materials – can be reversed between hydrophobic and hydrophilic states by applying ultraviolet (UV) irradiation. However, an explanation for this behavior has remained elusive. Recently, researchers at The University of New South Wales and University of Technology, Sydney investigating this phenomenon both experimentally and by calculations using density functional theory (DFT) – a computational quantum mechanical modeling method – finding that UV irradiation enables this reversible and controllable transition in graphene films having induced defects by water splitting adsorption on the graphene surface of H2O molecules in air. (Water splitting is the chemically dissociative reaction in which water is separated into hydroxyl and hydrogen; hydroxyl is a chemical functional group containing an oxygen atom connected by a covalent bond to a hydrogen atom; and adsorption is the adhesion of atoms, ions, or molecules from a gas, liquid, or dissolved solid to a surface.)

Inside the rise of embryo adoption

Science Focus

original post »

Odessa Kershner is five weeks pregnant. However her babies, possibly triplets, have been inside her body for only three. And they're technically adopted.

Here's how that's possible.

She and her husband, Jeff, have wanted more children for years. But Jeff, a computer programmer for the Oregon Department of Transportation, struggles with Crohn's disease and colitis, which they were just beginning to understand could be transmitted genetically after the birth of their biological daughters. Besides, they had always felt called to adopt.

Despite their qualifications as a stable, loving family, adoption...

California’s most productive fisheries? Offshore oil rigs

Science Focus

original post »
One of the more unusual recent developments in ocean conservation has been the use of artificial reefs. Old ships and even old subway cars have been used to create environments for fish to congregate in areas of the seafloor that are otherwise featureless. But it's not clear whether these habitats provide a place for fish to gather or actually boost the fish populations in the area.

A new study looked at the productivity of a different sort of artificial reef: the oil and natural gas rigs that dot the state's coastline. The report finds that the oil rigs are the most productive fisheries ever measured—not only in California but in the entire world. The report notes that many of these platforms will be obsolete over the coming decades, and we might want to think about what we do when we're done using them for their original purpose.

There are different ways of measuring an ecosystem's productivity. One is primary productivity, or how much carbon dioxide is converted into useful organic molecules by plants and other photosynthetic organisms. Then there's secondary productivity, defined as how much of that finds its way to herbivores and predators. In this case, the authors were interested in fish, so they focused on secondary productivity.

Serious security: Device-Independent Quantum Key Distribution guards against the most general attacks

more »

The Holy Grail of quantum cryptography – beyond delivering security that cannot be classically achieved – is guaranteeing unconditional security when the untrusted quantum devices are involved. While this goal has been studied since the early 1990s, a robust solution has proven elusive. Although Jonathan Barrett and his co-authors published2,3 a strong Device-Independent Quantum Key Distribution (DIQKD) security guarantee in 2005, it focused on a weaker set of constraints than those imposed by quantum mechanics – specifically, the no-signaling property dictated by special relativity – which thereby yielded stronger results. At the same time, however, it had several drawbacks, including low efficiency and, most importantly, an assumption of independence between the different occurrences when the devices are used.

Supernova discoveries are reported to the International Astronomical Union's Central Bureau for Astronomical Telegrams, which sends out a circular with the name it assigns to it. The name is the year of discovery, immediately followed by a one or two-letter designation. The first 26 supernovae of the year are designated with a capital letter from A to Z. Afterward pairs of lower-case letters are used: aa, ab, and so on.[36] Since 2000, professional and amateur astronomers find several hundreds of supernovae each year (572 in 2007, 261 in 2008, 390 in 2009). For example, the last supernova of 2005 was SN 2005nc, indicating that it was the 367th[nb 1] supernova found in 2005.[37][38] Historical supernovae are known simply by the year they occurred: SN 185, SN 1006, SN 1054, SN 1572 (Tycho's Nova) and SN 1604 (Kepler's Star). Since 1885 the letter notation has been used, even if there was only one supernova discovered that year (e.g. SN 1885A, 1907A, etc.)—this last happened with SN 1947A. "SN", for SuperNova, is a standard prefix. Until 1987, two-letter designations were rarely needed; since 1988, however, they have been needed every year.

Galaxies, Stars and Nebulae series A gorgeous design featuring a composite image of the Cat's Eye nebula from NASA's Chandra X-ray Observatory and the Hubble Space Telescope.
This famous nebula represents a phase of stellar evolution after a star like our Sun runs out of fuel. In this phase, a star becomes an expanding red giant and sheds some of its outer layers, eventually leaving behind a hot core that collapses to form a dense white dwarf star. A fast wind emanating from the hot core rams into the ejected atmosphere, pushes it outward, and creates the graceful filamentary structures.
