The Giant Marilyn Monroe In Chicago


    The Giant Marilyn Monroe 26ft-statue and labeled “Forever Marilyn by 80-year-old”  by New Jersey sculptor Steward Johnson. The statue has been described as "sexist" and "creepy" by critics. Yes, at last! Now I know what Marilyn Monroe panties look alike! :P

Name Can Be Seen From Space


    A mysterious billionaire from the United Arab Emirates Hamad Bin Hamdan Al Ahyan, has carved his name on an island near Abu Dhabi, and it is so large that it can be seen from space. Each letter of his name is more than a half a kilometer long. As a result, his name is so big that it spans three kilometers.

Hubble captures bubbles and baby stars

    Hubble captures bubbles and baby stars (6/22/10)
    The NASA/ESA Hubble Space Telescope captures a complex network of gas clouds and star clusters within our neighbouring galaxy, the Large Magellanic Cloud. This region of energetic star birth is one of the most active in the nearby Universe.

    The Large Magellanic Cloud contains many bright bubbles of glowing gas. One of the largest and most spectacular is LHA 120-N 11, from the catalogue compiled in 1956 by the late astronomer and astronaut Karl Henize. It is informally known as N11.

    Close up, N11’s billowing pink clouds of glowing gas resemble a puffy swirl of fairground candyfloss. From further away, its distinctive overall shape led some observers to nickname it the Bean Nebula. The dramatic and colourful features in the nebula are the telltale signs of star birth.

    N11 is a well-studied region that extends across 1000 light-years. It is the second largest star-forming region within the Large Magellanic Cloud and has produced some of the most massive stars known.

Selected readings 9/28/10

    Interesting reading and news items.

    Please leave some comments that indicate which articles you find most interesting or that identify topics you would like to read about, and I will try to include more articles of a similar nature in the future

    These items are also bookmarked at my Diigo account.

    Convincing a Young Scientist that Dark Matter Exists
    So I was in favor of dark matter, but I wasn't entirely convinced. I wanted a "smoking gun" piece of evidence for dark matter. Something that was an entirely new prediction that we could look for -- much like that 1919 eclipse was for general relativity -- and decide whether dark matter predicts what we're going to see. [Starts with a Bang, 6/24/10]
    How blind to change are you?
    This failure to notice what should be very apparent is something we unconsciously experience every day as our brains filter the barrage of visual information which we are flooded with. And apparently it has a name; it is called change blindness. [BBC News, 6/11/10]
    New data suggest a lighter Higgs
    New data offer evidence that the heft of the Higgs particle lies somewhere in the low end of the range being probed by particle colliders on two continents. The results also hint that the particle’s mass may be consistent with supersymmetry, a theory that gives every particle in the standard model of physics a much heavier partner. [Science News, 7/26/10]
    Jellyfish eye genes suggest a common origin for animal eyes
    Jellyfish may seem like simple blobs but some have surprisingly sophisticated features, including eyes. These are often just light-sensitive pits but species like the root-arm medusa have complex ‘camera’ eyes, with a lens that focuses light onto a retina. Not only are these organs superficially similar to ours, they’re also constructed from the same genetic building blocks. [Not Exactly Rocket Science, 7/27/10]
    Astronomy and particle physics race to replace Standard Model
    If energy issues seem to be attracting the attention of a lot of physicists, the Large Hadron Collider seems to be drawing the attention of many of the rest of them, including people in fields like cosmology, which deals with items on the opposite end of the size scale. In turn, the people working on the LHC and other particle detectors are carefully paying attention to the latest astronomy results, hoping they'll put limits on the properties and identities of the zoo of theoretical particles that need to be considered. [Nobel Intent, 7/28/10]
    Genetics tells tall tales
    Studies scanning the genomes of tens of thousands of individuals for gene variants associated with height have come up short: around 50 variants have been identified, but together they account for only 5% or so of height's heritability. ... This heritability may not be missing — it may simply be buried deeper than previously thought, in a multitude of genetic variants that have tiny effects individually. [Nature News, 6/20/10]
    Dark matter eldorado
    Observations confirm that a faint group of stars in the Milky Way’s backyard has the highest density of dark matter — the invisible material thought to account for 83 percent of the mass of the universe — of any galaxy known. [Science News, 7/30/10]
    Searching through the LHC data flood for dark matter
    Although the Standard Model has needed some minor tweaking to deal with recent observations, Gross said that there are three major issues that suggests it's due for a major overhaul. One of these is that we have convincing evidence that dark matter exists, and comes in the form of particles that are heavy and stable to at least the life of the Universe. Unfortunately, the Standard Model provides nothing that meets these requirements. [Nobel Intent, 8/1/10]
    Two New Paths to the Dream: Regeneration
    Animals like newts and zebra fish can regenerate limbs, fins, even part of the heart. If only people could do the same, amputees might grow new limbs and stricken hearts be coaxed to repair themselves. But humans have very little regenerative capacity, probably because of an evolutionary trade-off: suppressing cell growth reduced the risk of cancer, enabling humans to live longer. A person can renew his liver to some extent, and regrow a fingertip while very young, but not much more. [New York Times, 8/5/10]
    Sponge genes surprise
    A complete genetic catalog of the sponge Amphimedon queenslandica suggests that the first animals already had a complex kit of genetic tools at their disposal. Sponges harbor between 18,000 and 30,000 genes — roughly the same number as humans, fruit flies, roundworms and other animals. [Science News, 8/4/10]
    Plentiful and Potential Planets
    Two planet-hunting telescopes - CoRoT and Kepler - are keeping astronomers hard at work cataloging far-distant planets that orbit other stars in our galaxy. The search for distant planets is essential for astrobiologists who are hunting for habitable, Earth-like worlds beyond our solar system. [Physorg.com, 6/23/10]
    World’s Most Intense X-Ray Laser Takes First Shots
    The world’s most intense X-ray laser may soon be the fastest strobe-light camera ever. Two of the laser’s first experiments show the device will be able to take snapshots of single molecules in motion — without destroying them first. [Wired Science, 6/30/10]
    The origin of life: putting chemistry inside a cell
    In Szostak's view, interesting chemistry is easy. He also said that Darwinian evolution also makes things easy, since it's possible to take what you've got and radically improve it. So what's bugging him these days is the transition in between the two. How do you move from interesting chemistry to something that can evolve? He's doing this by trying to engineer a system that can make the transition. [Nobel Intent, 6/28/10]
    Why weather != climate: the engine behind climate models
    In this article I take a look at climate modeling and in particular why the comment "They can't predict the weather, therefore climate models are not good" is just plain wrong. It represents a fundamental misunderstanding of what climate modelers are trying to achieve, what is achievable and why the weather is unpredictable. [Nobel Intent, 7/9/10]
    Does Your Language Shape How You Think?
    The habits of mind that our culture has instilled in us from infancy shape our orientation to the world and our emotional responses to the objects we encounter, and their consequences probably go far beyond what has been experimentally demonstrated so far; they may also have a marked impact on our beliefs, values and ideologies. We may not know as yet how to measure these consequences directly or how to assess their contribution to cultural or political misunderstandings. But as a first step toward understanding one another, we can do better than pretending we all think the same. [New York Times, 8/26/10]
    Stem Cell Biology and Its Complications
    Stem cell biology turned out to be more complicated than they anticipated. Besides the stem cells from embryos, there are so-called adult stem cells found in all tissues but with limited potential because they can only turn into cells from their tissue of origin. And there are these newer cells made by reprogramming mature cells. [New York Times, 8/24/10]
    Scientists Square Off on Evolutionary Value of Helping Relatives
    For the past 46 years, biologists have used Dr. Hamilton’s theory to make sense of how animal societies evolve. They’ve even applied it to the evolution of our own species. But in the latest issue of the journal Nature, a team of prominent evolutionary biologists at Harvard try to demolish the theory. [New York Times, 8/30/10]
    Think You're Operating on Free Will? Think Again
    There may be few things more fundamental to human identity than the belief that people are rational individuals whose behavior is determined by conscious choices. But recently psychologists have compiled an impressive body of research that shows how deeply our decisions and behavior are influenced by unconscious thought, and how greatly those thoughts are swayed by stimuli beyond our immediate comprehension. [Time, 7/2/10]
    Forget What You Know About Good Study Habits
    In recent years, cognitive scientists have shown that a few simple techniques can reliably improve what matters most: how much a student learns from studying. The findings can help anyone, from a fourth grader doing long division to a retiree taking on a new language. But they directly contradict much of the common wisdom about good study habits, and they have not caught on. [New York Times, 9/6/10]
    Gene networks underlie disease?
    An international group of researchers have developed a novel method for identifying entire networks of genes and their association to disease, providing a more accurate picture of the genetic risks associated with specific diseases than single genes can provide. [The Scientist, 9/8/10]
    Collider gets yet more exotic 'to-do' list
    As if the Large Hadron Collider (LHC) didn't have enough to look for. It is already charged with hunting for the fabled Higgs boson, extra dimensions and supersymmetry, but physicists are now adding even more elaborate phenom­ena to its shopping list — including vanishing dimensions that could explain the accelerating expansion of the Universe. Some argue that signs of new and exotic physics could show up in the LHC far sooner than expected. [Nature News, 7/20/10]
    Under Pressure: The Search for a Stress Vaccine
    Chronic stress, it turns out, is an extremely dangerous condition. ... While stress doesn’t cause any single disease — in fact, the causal link between stress and ulcers has been largely disproved — it makes most diseases significantly worse. The list of ailments connected to stress is staggeringly diverse and includes everything from the common cold and lower-back pain to Alzheimer’s disease, major depressive disorder, and heart attack. [Wired Magazine, 7/28/10]
    Why some memories stick
    A study published in Science this week indicates that reactivating neural patterns over and over again may etch items into the memory. People find it easier to recall things if material is presented repeatedly at well-spaced intervals rather than all at once. For example, you're more likely to remember a face that you've seen on multiple occasions over a few days than one that you've seen once in one long period. One reason that a face linked to many different contexts — such as school, work and home — is easier to recognize than one that is associated with just one setting, such as a party, could be that there are multiple ways to access the memory. This idea, called the encoding variability hypothesis, was proposed by psychologists about 40 years ago. [Nature News, 9/9/10]
    DNA 'Volume Knobs' May Be Associated With Obesity
    When it comes to our expanding waistlines, we usually blame either diet or genes. But a new study fingers a third culprit: chemicals that attach to DNA and change its function. A survey of millions of these modifications has uncovered a handful associated with body mass index, a measure of height and weight. [Science Now, 9/15/10]
    Astronomy and particle physics race to replace Standard Model
    If energy issues seem to be attracting the attention of a lot of physicists, the Large Hadron Collider seems to be drawing the attention of many of the rest of them, including people in fields like cosmology, which deals with items on the opposite end of the size scale. In turn, the people working on the LHC and other particle detectors are carefully paying attention to the latest astronomy results, hoping they'll put limits on the properties and identities of the zoo of theoretical particles that need to be considered. [Nobel Intent, 7/28/10]
    Sizing Up Consciousness by Its Bits
    Consciousness, Dr. Tononi says, is nothing more than integrated information. Information theorists measure the amount of information in a computer file or a cellphone call in bits, and Dr. Tononi argues that we could, in theory, measure consciousness in bits as well. When we are wide awake, our consciousness contains more bits than when we are asleep. [New York Times, 9/20/10]
    Translating Stories of Life Forms Etched in Stone
    The Ediacaran fossils tell us that Darwin was being too generous. Our earliest animal ancestor probably had no head, tail, or sexual organs, and lay immobile on the sea floor like a door mat. [New York Times, 7/26/10]

A Galactic Spectacle

    A Galactic Spectacle (8/5/10)
    The Antennae galaxies, located about 62 million light years from Earth, are shown in this composite image from the Chandra X-ray Observatory (blue), the Hubble Space Telescope (gold and brown), and the Spitzer Space Telescope (red). The Antennae galaxies take their name from the long antenna-like "arms," seen in wide-angle views of the system. These features were produced by tidal forces generated in the collision.

    The collision, which began more than 100 million years ago and is still occurring, has triggered the formation of millions of stars in clouds of dusts and gas in the galaxies. The most massive of these young stars have already sped through their evolution in a few million years and exploded as supernovas.

    The X-ray image from Chandra shows huge clouds of hot, interstellar gas that have been injected with rich deposits of elements from supernova explosions. This enriched gas, which includes elements such as oxygen, iron, magnesium and silicon, will be incorporated into new generations of stars and planets.

An Elegant Galaxy in an Unusual Light

    An Elegant Galaxy in an Unusual Light (9/22/10)
    A new image taken with the powerful HAWK-I camera on ESO’s Very Large Telescope at Paranal Observatory in Chile shows the beautiful barred spiral galaxy NGC 1365 in infrared light. NGC 1365 is a member of the Fornax cluster of galaxies, and lies about 60 million light-years from Earth. ...

    The new infrared images from HAWK-I are less affected by the dust that obscures parts of the galaxy than images in visible light and they reveal very clearly the glow from vast numbers of stars in both the bar and the spiral arms. These data were acquired to help astronomers understand the complex flow of material within the galaxy and how it affects the reservoirs of gas from which new stars can form. The huge bar disturbs the shape of the gravitational field of the galaxy and this leads to regions where gas is compressed and star formation is triggered. Many huge young star clusters trace out the main spiral arms and each contains hundreds or thousands of bright young stars that are less than ten million years old. The galaxy is too remote for single stars to be seen in this image and most of the tiny clumps visible in the picture are really star clusters. Over the whole galaxy, stars are forming at a rate of about three times the mass of our Sun per year.

    While the bar of the galaxy consists mainly of older stars long past their prime, many new stars are born in stellar nurseries of gas and dust in the inner spiral close to the nucleus. The bar also funnels gas and dust gravitationally into the very centre of the galaxy, where astronomers have found evidence for the presence of a super-massive black hole, well hidden among myriads of intensely bright new stars.

An "Island Universe" in the Coma Cluster

    An "Island Universe" in the Coma Cluster (8/10/10)
    A long-exposure Hubble Space Telescope image shows a majestic face-on spiral galaxy located deep within the Coma Cluster of galaxies, which lies 320 million light-years away in the northern constellation Coma Berenices.

    The galaxy, known as NGC 4911, contains rich lanes of dust and gas near its center. These are silhouetted against glowing newborn star clusters and iridescent pink clouds of hydrogen, the existence of which indicates ongoing star formation. Hubble has also captured the outer spiral arms of NGC 4911, along with thousands of other galaxies of varying sizes. The high resolution of Hubble's cameras, paired with considerably long exposures, made it possible to observe these faint details.

    NGC 4911 and other spirals near the center of the cluster are being transformed by the gravitational tug of their neighbors. In the case of NGC 4911, wispy arcs of the galaxy's outer spiral arms are being pulled and distorted by forces from a companion galaxy (NGC 4911A), to the upper right. The resultant stripped material will eventually be dispersed throughout the core of the Coma Cluster, where it will fuel the intergalactic populations of stars and star clusters.

    The New Nu News!
    There could be an extra, "sterile" neutrino out there, although cosmology places tight restrictions on that. There could be a fundamental difference between neutrinos and anti-neutrinos, which we don't (at present) understand at all. Or there could be some physics that's completely off the radar that explains this, but it looks like the good ol' standard model (and the simplest modifications to it) is woefully inadequate to explain what we're seeing. [Starts with a Bang, 9/27/10]
    Primordial Magnetic Field May Permeate the Universe
    Two physicists attempting to overcome some unexpected fuzziness in images of distant, supermassive black holes say they have found yet another potential big bang vestige: an extremely weak magnetic field that stretches across the universe. If scientists confirm the finding, it could help reveal the origins of magnetism in the cosmos. [ScienceNOW, 9/24/10]
    The Itch of Curiosity
    Curiosity is one of those personality traits that gets short scientific shrift. It strikes me as a really important mental habit - how many successful people are utterly incurious? - but it's also extremely imprecise. What does it mean to be interested in seemingly irrelevant ideas? And how can we measure that interest? While we've analyzed raw intelligence to death - scientists are even beginning to unravel the anatomy of IQ - our curiosity about the world remains mostly a mystery. [Wired, 8/3/10]
    The Personality Paradox
    There's an interesting new paper in Biological Psychiatry on the genetic variations underlying human personality. The study relied on a standard inventory of temperaments - novelty-seeking, harm avoidance, reward dependence and persistence - as measured in 5,117 Australian adults. What did the scientists find? Mostly nothing. The vast genetic search came up empty. [Wired, 8/9/10]
    The Worm In Your Brain
    So our cortex turns out to be a lot older than previously thought. The common ancestor of us and ragworms–a wormy creature that lived 600 million years ago–not only had a brain, but had an ur-cortex. And it probably used that ur-cortex to learn about its world–most likely learning about the odors it sniffed. That animal’s descendants diverged into different forms, and the ur-cortex changed along the way. Yet they still used many of the same genes their ancestor did long ago. [The Loom, 9/3/10]
    Mapping the Brain on a Massive Scale
    A massive new project to scan the brains of 1,200 volunteers could finally give scientists a picture of the neural architecture of the human brain and help them understand the causes of certain neurological and psychological diseases. The National Institutes of Health announced $40 million in funding this month for the five-year effort, dubbed the Human Connectome Project. Scientists will use new imaging technologies, some still under development, to create both structural and functional maps of the human brain. [Technology Review, 9/28/10]
    Recipes For Limb Renewal
    Bioengineers continue to refine prosthetic limbs, but they still can’t replicate the entire constellation of capabilities provided by flesh and blood. So a few determined scientists are pursuing a different solution: They are seeking the recipe for regrowing a missing limb. [Chemical & Engineering News, 8/2/10]
    If low serotonin levels aren't responsible for depression, what is?
    While traditional antidepressants do increase neurogenesis and relieve depression symptoms in some animal models, others show that neurogenesis and antidepressant behaviours are unrelated. Much of this debate comes down to the fact that we don't yet have a real understanding of neurogenesis, how it works, and how it is controlled both in normal brains and in the presence of antidepressants. Until we know, finding a truly effective antidepressant may remain out of reach. So while the monoamine/serotonin hypothesis for depression may be out, neurogenesis needs to step it up a little to make it in. [guardian.co.uk, 9/28/10]
    A New Way to Make Stem Cells
    A Harvard researcher has developed a way to make pluripotent stem cells that solves several of the major impediments to using them to treat human diseases. Derrick Rossi, an assistant professor at Harvard Medical School, created pluripotent stem cells--which can turn into virtually any other type of cell in the body--from non-stem cells without using viruses to tinker with a cell's genome, as conventional methods do. This means that Rossi's method could be substantially safer for treating disease. [Technology Review, 10/1/10]
    Alien World Tour: The Exoplanets Around Star Gliese 581
    The announcement Wednesday (Sept. 29) of two newfound alien planets circling the star Gliese 581 adds to the nearby solar system's intrigue, further cementing its status as a top candidate to harbor extraterrestrial life. One of the two newly discovered planets, known as Gliese 581g, is a small, Earth-like world that likely lies within its star's habitable zone - the just-right range of distances that allow liquid water to exist. Astronomers have now detected six planets orbiting Gliese 581, the most known to circle any star beyond our own sun. [Space.com, 9/29/10]
    If There's Life on Alien Planet Gliese 581g, How Do We Find It?
    After spending decades searching for alien planets capable of harboring life, astronomers may have found one. So how can they check to see if life actually exists on this alien world? ... One of the planet's discoverers said in a briefing yesterday that "the chances of life on this planet are 100 percent." To determine if this is true, researchers will have to scrutinize Gliese 581g from afar, searching its atmosphere for certain telltale molecules. But it might be a while before they have the tools to do this properly. [Space.com, 9/30,10]
    Astronomer Seeks ET Machines
    If we ever do receive a message from outer space, we’ll want to know what kind of aliens sent it. SETI researcher Seth Shostak says we shouldn’t expect them to be anything like us – in fact, they might not be biological at all, but instead, extraterrestrial machines. [Astrobiology Magazine, 10/1/10]
    The Gates of Immortality
    Why do cells allow some mistakes to accumulate? If evolution is such a powerful process-one that finds solutions to all manner of problems-how could there be processes or problems that can't be fixed? [The Scientist, 10/1/10]
    The One True Path?
    Niswender and Galli are elucidating a molecular link between mental illness and problems with how the body processes sugars. That link is part of the complex series of events that make up the insulin-signaling pathway, a crucial mechanism by which the pancreatic hormone insulin directs the transport and storage of glucose in virtually every cell type in the body. This is only one of a recent rash of discoveries about how insulin is also intricately involved in many disease processes, including the growth of cancer cells and defects in bone mass regulation. [The Scientist, 10/1/10]
    A new source of CP violation?
    Abazov et al. report an unexpectedly large value of the same-sign dimuon charge asymmetry. This means that they see pairs of positive muons, μ+μ+, among the debris of their proton-antiproton collisions more often than they see pairs of negative muons, μ-μ-. The key point is that their measurement violates CP symmetry, which relates the behavior of matter and antimatter particles. [Physics, 8/16/10]
    Hagfish Analysis Opens Major Gap in Tree of Life
    Since the 1970s, many evolutionary biologists have considered an eel-like, deep-sea-dwelling creature called the hagfish to be the closest extant relative of a last common ancestor for all backboned creatures. That made the hagfish a stand-in for a transitional species between invertebrates and higher animals, spanning a leap as dramatic as any in evolutionary history. But a new family tree based on high-powered molecular analysis lumps hagfish together with lampreys, a jawless fish that’s primitive, but very much a vertebrate. [Wired, 10/19/10]
    On a quest to map the brain’s hidden territory
    On a recent morning, Wedeen pulled up images created with the new technology, in which the lakes of white were crisscrossed by colorful, ropy bundles of fibers, revealing an elegant, three-dimensional architecture. Looking more like art than anatomy, these strands form the connections in the brain — the “connectome.’’ They are neural highways crucial for brain function, including thoughts, movements, and sensations. [The Boston Globe, 10/11/10]
    The origin of complex life – it was all about energy
    According to a new hypothesis, put forward by Nick Lane and Bill Martin, we are all natural-born gas-guzzlers. Our very existence, and that of every animal, plant and fungus, depended on an ancient partnership, forged a few billion years ago, which gave our ancestors access to unparalleled supplies of energy and allowed them to escape from the shackles of simplicity. [Not Exactly Rocket Science, 10/20/10]
    The Fuel Of Evolution
    Within the cells of humans and all other modern creatures are lots of tiny mitochondria, which may have been the key to the evolution of complex multicellular life billions of years ago. [InsideScience.org, 10/22/10]
    Geologists revisit the Great Oxygenation Event
    Why did oxygen levels spike 2.5 billion years ago, and how much oxygen was there in the atmosphere really? Why are banded iron formations made of layers only a few centimeters thick, and why did they stop forming so abruptly? If the oceans were oxygenated 2.5 billion years ago, why did multicellular life delay its appearance for another 2 billion years? And did all these changes really take place at pretty much the same time everywhere on Earth? [Physorg.com, 8/19/10]
    Mirror Mirror On The Wall
    Every one of the four forces of Nature we know of - gravity, electromagnetism, the weak force, and the nuclear force - all originate from slight variations of this narrative. Gauge symmetries are the origins of all the forces of Nature. For example, gravity arises from a gauge symmetry in 3D: a sphere of a gauge with its hand pointing in any direction in the full three dimensional span of space. [Schrödinger's Dog, 10/22/10]
    Gravity Up Close
    Scientists know how gravity works at big distances -- the inter-planetary or inter-stellar range -- but does it work the same way at the inter-atomic range? A variety of tabletop experiments are trying to explore this issue. Already some theorists say that a departure from conventional gravity behavior could hint at the existence of extra dimensions. [InsideScience.org, 10/13/10]
    Cracks In The Universe
    Physicists are hot on the trail of one of strangest theorized structures in the universe. A team of researchers have announced what they think are the first indirect observations of ancient cosmic strings, bizarre objects thought to have contributed to the arrangement of objects throughout the universe.

Young stars biting the cloud that feeds them

    Young stars biting the cloud that feeds them (8/30/10)
    A billowing cloud of hydrogen in the Triangulum galaxy (Messier 33), about 2.7 million light-years away from Earth, glows with the energy released by hundreds of young, bright stars. This NASA/ESA Hubble Spare Telescope image provides the sharpest view of NGC 604 so far obtained.

    Some 1500 light-years across, this is one of the largest, brightest concentrations of ionised hydrogen (H II) in our local group of galaxies, and is a major centre of star formation.

    The gas in NGC 604, around nine tenths of it hydrogen, is gradually collapsing under the force of gravity to create new stars. Once these stars have formed, the vigorous ultraviolet radiation they emit excites the remaining gas in the cloud, making it glow a distinct shade of red. This colour is typical not only of NGC 604 but of other H II regions too.
