    Don’t you hate it when you get up in the morning and the first thing you read on the internet is that the news that your entire career has been a waste of time, your whole field of study has collapsed, and you’re going to have to rethink your entire future? Happens to me all the time. But then, I read the creationist news, so I’ve become desensitized to the whole idea of intellectual catastrophes. Today’s fresh demolition of the whole of evolutionary theory comes via Christian News, which reports on a paper in the journal Molecular Biology and Evolution which…

    In 1915, a thirty-six year old Albert Einstein had just finished completing the two-page masterpiece that would revolutionize modern physics and catapult the struggling physicist into international fame and glory – the theory of general relativity. Before it was published though, Einstein paused for a moment and wrote a most heartfelt and considerate letter to his then 11-year old son Hans Albert, who was living with his estranged mother and little brother, Eduard “Tete” Einstein, in Vienna. The letter (featured below), like most of Einstein’s correspondence, shines of…

More importantly, the work reveals how behaviors of group members can pull bad policy up or drag good policy down. The work is published in this week’s Proceedings of the National Academy of Sciences. “This paper finds that group size does matter—and the answer is right in the middle,”…

This particular H7N9 strain is considered to be one of the most worrisome pathogens since the H5N1 pandemic in 1997; a reputation based on the virus’ ability to spread easily across species and to infect humans.

    For the past the 1,000,000 years the global climate has cycled every 100,000 years, between long glacial periods (with great masses of ice covering the continents in the northern hemisphere) and shorter interglacial periods, lasting around 10,000 years. It has been 12,000 years since the last one so enjoy that while it lasts. However, within the long periods there have been abrupt climate changes, sometimes happening in the space of just a few decades, with variations of up to 10º C in the average temperature in the polar regions caused by changes in the Atlantic ocean circulation.

Good thing too, or entire generations of children would be mentally stunted - not drinking at all during pregnancy became the cultural norm a generation ago and it used the same kinds of longitudinal study that now says moderate drinking is okay. And more affluent and better educated mums-to-be tend to drink more than women who are less well off, say the researchers, which…

    Goals need to be flexible, according to a new paper.  People who set a goal of losing between 2 and 4 pounds will still lose an average of 3 lbs. while a person who targets 3 lbs. specifically has less chance of success.  Consumers often have a choice about the types of goals they want to set for themselves, and they may want to repeat various goals over time. For example, consumers often reengage goals such as losing weight, saving money, or improving their exercise or sports performance. read more

They found strong evidence for the association between smoking and perioperative complications throughout the surgical literature.  read more

    Apparently, the Guiding Movement is to upgrade its pledge that all members must make when they join.

It’s dodgy, it seems, to say the least, and the US Food & Drug Administration does not allow its legal sale as a food supplement. Here’s what Andrey Pavlov doggedly had to say about DMAA in a recent Science-based Medicine post: “…there is no reasonable way that DMAA can be considered a natural or safe product for sale as a supplement under the DSHEA (US Dietary Supplement Health and Education Act). And even if it did meet DSHEA requirements, this is an excellent example…

    One of the funny things about language is that everybody has their own. There is no "English" out there, existing independently of all its speakers.

This hypothesis makes the clear -- and almost certainly false -- prediction that people are likely to adopt…

    We’re taught from childhood how important it is to explain how we feel and to always justify our actions. But does giving reasons always make things clearer, or could it sometimes distract us from our true feelings? One answer came from a study led by psychology professor Timothy Wilson at the University of Virginia, which asked university students to report their feelings, either with or without being asked to provide reasons. What they found revealed just how difficult it can be to reliably discern our feelings when justifying our decisions. Participants were asked to evaluate five…

We worked in a small town called Adasawase to determine prevalence and treat the schoolchildren who were infected. We were told that schistosomiasis was not a major health concern for the people in the town because they were often faced with other diseases that had more immediate and severe health consequences than a parasitic infection. It became apparent that if we wanted the people of this small town to take this health threat seriously, we needed to…

    Greg Laden
    18 Jun 2013 | 9:24 am
    There have been times in the past when there was very little ice trapped in glaciers. During this time, sea levels were higher because that water was in the ocean (most of it, anyway). It has been a long time since then. However, with global warming, more and more glacial ice is returning to the sea and this contributes to sea level rise. The amount of fossil carbon that needs to be released into the atmosphere to cause most of the glacial ice to melt is not known. We can’t directly use ancient time periods to assess modern sea level rise by measuring the sea levels from those periods…

  • Quasi Poll: Most Needed Pop-Science Biography? [Uncertain Principles]

    Chad Orzel

    I’ve got a ton of stuff that needs to get done this week, but I don’t want the blog to be completely devoid of new content, so here’s a quasi-poll question for my wise and worldly readers: What scientist is most in need of a good popular biography? By “popular biography,” I mean things like Norton’s Great Discoveries books, several of which Ive reviewed here, including Krauss on Feynman and Reeves on Rutherford, two books that I keep coming back to for useful tidbits. These aren’t deep works of historical scholarship, and don’t necessarily…

  • Transcription-Factor-Mediated DNA Looping Probed by High-Resolution, Single-Molecule Imaging in Live E. coli Cells

    Zach Hensel et al.
    18 Jun 2013 | 2:00 pm
    by Zach Hensel, Xiaoli Weng, Arvin Cesar Lagda, Jie Xiao DNA looping mediated by transcription factors plays critical roles in prokaryotic gene regulation. The “genetic switch” of bacteriophage λ determines whether a prophage stays incorporated in the E. coli chromosome or enters the lytic cycle of phage propagation and cell lysis. Past studies have shown that long-range DNA interactions between the operator sequences OR and OL (separated by 2.3 kb), mediated by the λ repressor CI (accession number P03034), play key roles in regulating the λ switch. In vitro, it was demonstrated that…

  • Transdifferentiation of Fast Skeletal Muscle Into Functional Endothelium in Vivo by Transcription Factor Etv2

    Matthew B. Veldman et al.
    18 Jun 2013 | 2:00 pm
    by Matthew B. Veldman, Chengjian Zhao, Gustavo A. Gomez, Anne G. Lindgren, Haigen Huang, Hanshuo Yang, Shaohua Yao, Benjamin L. Martin, David Kimelman, Shuo Lin Etsrp/Etv2 (Etv2) is an evolutionarily conserved master regulator of vascular development in vertebrates. Etv2 deficiency prevents the proper specification of the endothelial cell lineage, while its overexpression causes expansion of the endothelial cell lineage in the early embryo or in embryonic stem cells. We hypothesized that Etv2 alone is capable of transdifferentiating later somatic cells into endothelial cells. Using heat shock…

    by J. Christoph Vahl, Klaus Heger, Nathalie Knies, Marco Y. Hein, Louis Boon, Hideo Yagita, Bojan Polic, Marc Schmidt-Supprian Natural killer T (NKT) cell development depends on recognition of self-glycolipids via their semi-invariant Vα14i-TCR. However, to what extent TCR-mediated signals determine identity and function of mature NKT cells remains incompletely understood. To address this issue, we developed a mouse strain allowing conditional Vα14i-TCR expression from within the endogenous Tcrα locus. We demonstrate that naïve T cells are activated upon replacement of their endogenous…

    by S. G. Raju, Annika F. Barber, David N. LeBard, Michael L. Klein, Vincenzo Carnevale Despite the clinical ubiquity of anesthesia, the molecular basis of anesthetic action is poorly understood. Amongst the many molecular targets proposed to contribute to anesthetic effects, the voltage gated sodium channels (VGSCs) should also be considered relevant, as they have been shown to be sensitive to all general anesthetics tested thus far. However, binding sites for VGSCs have not been identified. Moreover, the mechanism of inhibition is still largely unknown. The recently reported atomic…

    by Hannah C. Slater, Manoj Gambhir, Paul E. Parham, Edwin Michael Malaria and lymphatic filariasis (LF) continue to cause a considerable public health burden globally and are co-endemic in many regions of sub-Saharan Africa. These infections are transmitted by the same mosquito species which raises important questions about optimal vector control strategies in co-endemic regions, as well as the effect of the presence of each infection on endemicity of the other; there is currently little consensus on the latter. The need for comprehensive modelling studies to address such questions is…

    by Urko M. Marigorta, Arcadi Navarro Genome-wide association studies (GWAS) have detected many disease associations. However, the reported variants tend to explain small fractions of risk, and there are doubts about issues such as the portability of findings over different ethnic groups or the relative roles of rare versus common variants in the genetic architecture of complex disease. Studying the degree of sharing of disease-associated variants across populations can help in solving these issues. We present a comprehensive survey of GWAS replicability across 28 diseases.

  • Meiosis-Specific Stable Binding of Augmin to Acentrosomal Spindle Poles Promotes Biased Microtubule Assembly in Oocytes

    by Nathalie Colombié, A. Agata Głuszek, Ana M. Meireles, Hiroyuki Ohkura In the oocytes of many animals including humans, the meiotic spindle assembles without centrosomes. It is still unclear how multiple pathways contribute to spindle microtubule assembly, and whether they are regulated differently in mitosis and meiosis. Augmin is a γ-tubulin recruiting complex which “amplifies” spindle microtubules by generating new microtubules along existing ones in mitosis. Here we show that in Drosophila melanogaster oocytes Augmin is dispensable for chromatin-driven assembly of bulk spindle…

  • The differences between a geek and a nerd

    Nathan Yau
    14 Jun 2013 | 8:59 am
    Curious about how people use "geek" and "nerd" to describe themselves and if there was any difference between the two terms, Burr Settles analyzed words used in tweets that contained the two. Settles used pointwise mutual information (PMI), which essentially provided a measure of the geekness or nerdiness of a term. The plot above shows the results. In broad strokes, it seems to me that geeky words are more about stuff (e.g., “#stuff”), while nerdy words are more about ideas (e.g., “hypothesis”). Geeks are fans, and fans collect stuff; nerds are practitioners, and practitioners play…

On each date, people scored each other on attractiveness, intelligence, ambition, and some other things, along with a yes or a no to seeing the other person again on a regular date. Fisman, et al. noted gender differences in mate selection, such as: "Women put greater weight on the intelligence and the race of partner, while men respond more to physical attractiveness." And this: "Men do not value women's intelligence or ambition when it…

    Saved by the printer! If you’ve been wondering about 3-D printing, it’s probably for the same reason we are. On May 17, we learned that surgeons had placed a life-saving support — built on a 3-D printer — into the airway of Kaiba Gionfriddo. Alejandro Roldan of the University of Wisconsin-Madison holds a printed, 3-D model of a heart against its computer design, which was based on a patient’s MRI scan. The system, still under development, could be used to guide surgery to repair defective organs. Using the realistic, printed model, the surgeon can perform “virtual…

    Lovejoy no killjoy: Comet cracks corona question! ENLARGE Modified from original graphic by Cooper Downs When Comet Lovejoy streaked past the sun, its tail formed a series of rapid squiggles as it was driven by the sun’s complex magnetic fields. Satellite images converted a chunk of ancient ice into a natural scientific instrument that reached where no artificial instrument will ever go. Those open magnetic fields drive the solar wind throughout the solar system. To explore the swirling magnetic fields surrounding our neighborhood star, scientists have press-ganged a “dirty…

    Eating organic? Roaches disdain key “junk-food” sweetener Video courtesy of Ayako Wada-Katsumata Even with fine doilies and silverware, “glucose-averse” roaches shun jelly. Their normal (“wild-type”) relatives cluster around the jelly, as you’d expect. About 30 years ago, many cockroach haters began to use baited traps that blended high-fructose corn syrup with insecticide. But within seven or eight years, the traps started losing their clout. “We first assumed that cockroaches were becoming resistant to insecticide, “says Coby Schal, a…

Prized for bright, color-fast colors, the manufacturing process also produced prodigious streams of toxic waste. As the plant, eventually renamed Ciba after its owner, the Swiss chemical giant, prospered, streams of waste filtered into the sandy soil and reached the Atlantic through a leaky pipe. Less obvious at the time, a field of municipal water wells a mile or so from the plant fence were…

    WTJ
    25 Mar 2013 | 4:26 am
    The transfer of a working kidney from a donor to someone, whose kidneys aren’t functioning properly, is known as a kidney transplant. This procedure is done to treat a kidney that has malfunctioned, and is replaced with a fully functional one. Kidney failure is majorly caused by diabetes, high blood pressure and Chronic glomerulonephritis, which is the scarring of the small filters in your kidney. Kidney failure can usually be treated with a strict diet, treatment and medicines for the base cause. If all these fail then the only option is to go for a kidney transplant. A kidney transplant…

  • Graphene-based oscillator reaches the ultrahigh-frequency band

    Physics Today
    18 Jun 2013 | 9:28 am
    Ars Technica: Graphene is not a natural semiconductor, but it is attractive for use in electronics because it is only one atom thick and still lets electrons move through it. Some devices have been made using graphene, but they tend to perform at low levels because of current leakage. One such device is a ring oscillator, a circuit made of an odd number of NOT gates arranged in series, where the last gate feeds into the first, and the output is the opposite of the input. The frequency of the oscillations in the output can be used to measure the effectiveness of the circuit, and previous…

  • Subduction-zone birth may be happening off Portuguese coast

    Physics Today
    18 Jun 2013 | 9:15 am
    New Scientist: Subduction zones occur where one tectonic plate is forced under its neighbor until it melts into the mantle. If an ocean lies between the plates, subduction can cause it to be squeezed out of existence within a gigayear. How the zones form is uncertain because the rock involved appears to be too strong to break or be subducted. Now João Duarte at Monash University in Melbourne, Australia, and his colleagues believe they have found an area off the southwestern coast of Portugal that is in the process of becoming a subduction zone. Portugal experienced major quakes in 1755 and…

    23 May 2013 | 7:47 pm
    Back in the 1980’s the late astronomer Carl Sagan’s phrase “billions of stars” caught the world’s imagination. Imagine – billions of stars in our own Milky Way galaxy. And now we know that there are billions of galaxies. That leads us to believe that there is an uncountable number of stars in the universe. A recent posting on NASA’s Kepler website puts the number of stars in our own Milky Way at 100 billion. And, based on data culled from the Kepler orbiting telescope, we now know that most of those stars are hosts to exoplanets. That’s at least…

    Harvard Stem Cell Institute (HSCI) researchers have identified in the most aggressive forms of cancer a gene known to regulate embryonic stem cell self-renewal, beginning a creative search for a drug that can block its activity. The gene, SALL4, gives stem cells their ability to continue dividing as stem cells rather than becoming mature cells. Typically, cells only express SALL4 during embryonic development, but the gene is re-expressed in nearly all cases of acute myeloid leukemia and 10 to 30 percent of liver, lung, gastric, ovarian, endometrial, and breast cancers, strongly suggesting it…

    18 Jun 2013 | 9:00 pm
    Recent studies linking bullying and depression, coupled with extensive media coverage of bullying-related suicide among young people, led to a CDC-assembled expert panel to synthesize the latest research about the complex relationship between youth involvement in bullying and suicide-related behaviors: 1) Bullying among youth is a significant public health problem, with widespread and often harmful results; 2) There is a strong association between bullying and suicide-related behaviors; and 3) Public health strategies can be applied to prevent bullying and suicide.

  • "Planets Billions of Years Older Than Earth May Exist in the Milky Way" (Featured Post)

    dailygalaxy.com
    18 Jun 2013 | 9:02 am
    Building a terrestrial planet requires raw materials that weren't available in the early history of the universe. The Big Bang filled space with hydrogen and helium. Chemical elements like silicon and oxygen - key components of rocks - had to be cooked up over time by stars. But how long did that take? How many of such heavy elements do you need to form planets? Studies have shown that Jupiter-sized gas giants tend to form around stars containing more heavy elements than the Sun. However, research by a team of astronomers completed last year found that planets smaller than Neptune are located…

  • Galaxy Starbursts Triggered by Dark Matter --A Herschel Space Observatory Discovery

    Most of the mass of any galaxy is expected to be "dark matter," the elusive X Factor that has yet to be detected but which astronomers believe must exist to provide sufficient gravity to prevent galaxies ripping themselves apart as they rotate. But ESA’s Herschel space observatory has discovered a population of dust-enshrouded galaxies that do not need as much "dark matter" as previously thought to collect gas and burst into star formation. With the end of Europe's Herschel Space Telescope (ground controllers put the Herschel Observatory in sleep mode yesterday), turning off the infrared…

Located on the border of Triangulum Australe (The Southern Triangle) and Norma (The Carpenter’s Square), this field covers part of the Norma Cluster (Abell 3627) as well as a dense area of our own galaxy, the Milky Way. The Norma Cluster is the closest massive galaxy cluster to the Milky Way, and lies about 220 million light-years away. The enormous mass concentrated here, and the consequent…

  • Alien Planet Discovery a Puzzle --Accepted Theory Says "It Can't Exist"

    dailygalaxy.com
    18 Jun 2013 | 3:20 am
    A team of researchers has discovered evidence that an extrasolar planet may be forming quite far from its star—- about twice the distance Pluto is from our Sun. Planet formation far away from a small parent star is at odds with the conventional planet-making dogma. Under the most accepted scenario, planets form over tens of millions of years from the slow accretion of dust, rocks, and gas. That happens most easily close to the central star, where orbital timescales are short. Even under a disk instability scenario, in which planets can collapse quickly from the disk, it's not clear such a…

    You should know two very important weather dates for your area if you want to grow vegetables successfully: ✓ The average date of the last frost in spring ✓ The average date of the first frost in fall These frost dates tell you several important things: ✓ When to plant: Cool-season vegetables are generally planted 4 to 6 weeks before the last spring frost. Fall planting of cool-season vegetables is less dependent on frost dates, but it’s usually done 8 to 12 weeks before the first fall frost. Warm-season vegetables are planted after the last spring frost or in late summer in warm…

    Before you go drooling over the luscious veggies in catalogs, in garden centers, and online, it’s good to know a little about the varieties you can choose from. If you select your veggie varieties before you design your garden, you can ensure that you have the proper amount of space and the best growing conditions. A variety is a selection of a particular type of vegetable that has certain predictable, desirable traits. These traits may include the following: ✓ Adaptation: Some varieties are particularly well adapted to certain areas and climates. For example, some tomato varieties…

    Choosing a site is the important first step in planning a vegetable garden. This may sound like a tough choice to make, but don’t worry; a lot of the decision is based on good old common sense. When you’re considering a site for your garden, remember these considerations: ✓ Keep it close to home. Plant your garden where you’ll walk by it daily so that you remember to care for it. Also, a vegetable garden is a place people like to gather, so keep it close to a pathway. Vegetable gardens used to be relegated to some forlorn location out back. Unfortunately, if it’s out of sight,…

Similarly, with current concerns about food safety, global warming, carbon footprints, and pollution, along with a desire to build a link to the Earth and our own neighborhoods, food gardening has become a simple and tasty solution. Food gardens aren’t just in backyards anymore. People grow food in containers on decks and patios, in community gardens, at schools, at senior…

    At two events of the Wolrd Science Festival in early June,  a group of five theoretical physicists debated whether we’re living in a multiverse, and more surprisingly, if our current understanding of the cosmos all but mandates that multiple universes exist. It all goes back to the instant of the Big Bang, the femtosecond that set the rules for all reality as we know it in scientific terms. Each tiny little quantum instability and flux was stretched and projected across billions of light years to influence the shape of galaxy clusters and the tiny filaments what underpin our mostly…

    We live in a world where digital information is exploding. Some 90% of the world’s data was generated in the past two years. The obvious question is: how can we store it all? In Nature Communications today, we, along with Richard Evans from CSIRO, show how we developed a new technique to enable the data capacity of a single DVD to increase from 4.7 gigabytes up to one petabyte (1,000 terabytes). This is equivalent of 10.6 years of compressed high-definition video or 50,000 full high-definition movies. So how did we manage to achieve such a huge boost in data storage? First, we need to…

At the time, I wasn’t particularly worried about the line in that track: “Be kind to your knees, you’ll miss them when they’re gone.” But, you get older, knees become more of a focus, so what are you to do if you suffer from osteoarthritis of the knee (thankfully, I don’t…yet). According to SBM, here’s what a massive scientific review of the various possible treatments has to say: Exercise – strong…

    Successful companies have solid brand names we recognise wherever we are in the world and they rarely change them – Coca Cola, Microsoft, Apple, Gap. Of course, there are successful companies that do re-brand, although usually when bigger companies subsume and split them up, think Imperial Chemical Industries, which was commonly known as ICI, which eventually became AstraZeneca and various other firms. Then, there was the ludicrous attempt by Britain’s state-owned “Royal Mail” to rebrand itself for the “modern” age as “Consignia. And, who could forget…

  • Dietary DMAA, dimethylamylamine, death

    DMAA was originally a decongestant but has been marketed as a “dietary supplement”. It’s dodgy, it seems, to say the least, and the US Food & Drug Administration does not allow its legal sale as a food supplement. Here’s what Andrey Pavlov doggedly had to say about DMAA in a recent Science-based Medicine post: “…there is no reasonable way that DMAA can be considered a natural or safe product for sale as a supplement under the DSHEA (US Dietary Supplement Health and Education Act). And even if it did meet DSHEA requirements, this is an excellent example…

  • With Condors on the Brink, California Considers a Lead-Bullet Ban for Hunters

    Tim Huntington, courtesy the Ventana Wildlife Society After teetering on the brink of extinction 30 years ago, the California condor has made a gradual recovery in the state. But scientists say hunters are hampering a full recovery – not because they’re shooting at condors, but because the giant scavenger birds swallow lead bullet fragments when hunters leave an animal carcass behind. The California legislature is considering a bill that would ban the use of lead bullets in hunting across the state. It would be the first statewide ban in the country and in the midst of a tense national…

    Anthony Titus, from Richmond Heights, Ohio, plants native grasses during an EPA-funded wetland restoration project. Think of a wetland like a kidney.  Just as kidneys filter blood in the body, wetlands filter pollutants out of waterways. This is an especially important task in some urban areas, where big storm events can overwhelm the sewers and cause an overflow into nearby creeks and streams. According to a 2009 Fish and Wildlife report, wetlands along eastern coastal areas, like the Great Lakes, are disappearing at a rapid clip, with yearly losses of nearly 60,000 acres. But projects are…

      When you think about recycling, you may picture newspapers stacked neatly on your curb for pickup, or those ubiquitous blue bins around your office filled with bottles and cans. But items like papers, plastics and glass represent only a fraction of what we could be recycling. Across America, landfills are still expanding rapidly. One of the major culprits is the debris from housing construction and demolition—much of which could actually be recycled. “People understand it’s not right to just throw things away,” says Robert Chapman, Executive Director of WARM Training Center.

    At-risk tropical coral reefs could be bought time by limiting the amount of warming experienced by the world’s oceans in the future suggest Bristol University researchers. The scientists used computer models to investigate how shallow-water tropical coral reef habitats might respond to climate change over the coming decades. “If sea surface temperatures continue to rise, our models predict a large habitat collapse in the tropical Western Pacific which would affect some of the most biodiverse coral reefs in the world. To protect shallow-water tropical coral reefs, the warming experienced…

Sequencing the flesh-eating water plant’s genome, which has 80 million DNA base pairs, has revealed that 97% of it consists of genes and small pieces of DNA that control these genes. The researchers suggest the plant has been deleting noncoding “junk” DNA from its genome over many generations. “The big story is that only 3% of the bladderwort’s genetic material is…

    Our internal circadian clock regulates daily life processes and is synchronized by external cues, the so-called Zeitgebers. The main cue is the light-dark cycle, whose strength is largely reduced in extreme habitats such as in the Arctic during the polar summer. Using a radiotelemetry system a team of researchers from the Max Planck Institute for Ornithology have now found, in four bird species in Alaska, different daily activity patterns ranging from strictly rhythmic to completely arrhythmic. These differences are attributed to the species’ mating systems and behaviours.read more

They are tough too; many hummingbirds migrate incredibly long distances.All of that comes at a cost, however: hummingbirds must eat several times their weight in nectar daily to stay alive. This means they may be especially vulnerable to climate change, as changes in local flower crops can mean starvation for the bitty birds. Recent studies suggest that there could be a mismatch between flowering times and the arrival of hummingbirds in their breeding…

    Microwave ovens have provided the mankind with the whole new way of cooking, quite unlike the conventional method followed since thousands of years. When cooking is done in the customary manner, the heat that comes from a conventional gas stove is transferred to food by conduction. The heat is passed first to the food's outer layers and then progressively to its inner ones.

    The autumn tints are the external signs of important internal changes taking place in the leaves. The green matter, chlorophyll, in the leaves plays an important part as it helps each leaf to work as a food-factory for the plant. In autumn, however, the trees prepare to give up active life for a season and the food-making activities of the leaves are over. Before the leaves fall, they return much useful material to the plant. Green pigment, sugar and other key substances retreat to the stem and roots. With the breaking up of the chlorophyll at this time, other pigments become visible.

    The expression has its origin in the Second world war when German fighter bombers (photo, below) carried out extensive air raids on Britain’s military as well as civilian targets. The civil defence authorities determined the degree of alertness on the basis of the number of approaching aircraft after having detected them on radar. Civilians were mobilized accordingly, Yellow, blue and red alerts represented increasing degree of readiness for the attack, red alert being the highest level of alarm.
