    Wellcome Images describes its 100,000 strong collection of high-resolution images as “one of the world’s richest and most unusual collections”. You cannot deny that making a nettle sting the subject of a photo is an unusual thing to do: The image above is a colourised scanning electron micrograph of the sting cells of a nettle leaf (Urtica dioica). The stings themselves are hollow spikes of silica (sand/glass) that snap easily when your bare knees or other body part brush against the leaves. The stinging contents of the spikes are released from a bulb at the base and contain…

    About one in five wounded soldiers suffers from traumatic brain injury, and an estimated 52 percent of those injuries are blast-induced neurotrauma. Some of those brain injuries are difficult to diagnose because people don’t always display obvious motor impairment or other neurological symptoms. “Many times they don’t even realize they’ve been injured, and this is particularly alarming because these injuries have been linked to severe long-term psychiatric and degenerative neurological dysfunction,” says Riyi Shi, a professor in the basic medical sciences…
  • Deep trenches in Pacific are younger than we thought

    28 Aug 2015 | 11:08 am
    Parts of the deep trenches in the Pacific Ocean are much “younger”—by as much as 50 million years—than previously believed. Scientists say the findings could change current thinking about how such deep-ocean trenches form. Using the research ship JOIDES Resolution, researchers examined core samples extracted from a subduction zone south of Japan. The samples were taken from water about 4,800 feet deep in the Pacific floor. A subduction zone is a huge underwater boundary that marks the collision between Earth’s tectonic plates. They are pieces of crust that slowly move…

There’s more than one way to get a passion for your work. “The good news is that we can choose to change our beliefs or strategies to cultivate passion gradually or seek compatibility from the outset, and be just as effective in the long run at achieving this coveted experience,” says Patricia Chen, a doctoral psychology student at the University of Michigan, and lead author of a new study.

    Mothers who were abused as children may be less confident in their parenting skills—and may in turn abuse their own children. Intervention programs for moms at-risk should do more than teach parenting skills. Experts say it’s important to bolster mothers’ self-confidence, as well. “We know that maltreated children can have really low self-esteem,” says Louisa Michl, a doctoral student in the psychology department at the University of Rochester. “And when they become adults, we’ve found that some of these moms become highly self-critical about their…

  • Two Saturdays: Why A 4 Day Work Week Might Make Sense

    The Conversation
    29 Aug 2015 | 11:39 am
    As we approach the August bank holiday and a three-day weekend, it is worth reassessing the amount of time we devote to work. What if all weekends could last for three or even four days? What if the majority of the week could be given over to activities other than work? What if most of our time could be devoted to non-work activities of our own choosing?To even pose these questions is to invite the criticism of Utopian thinking. While a fine idea in principle, working fewer hours is not feasible in practice. Indeed, its achievement would come at the expense of lower consumption and increased…

    Skylab came up in conversation the other day. And then I ran into Amy Shira Teitel’s video. So, naturally, a quick blog post. Skylab was brought down, ultimately, by interaction with the upper reaches of the atmosphere, which was in turn made more likely by solar activity. But, both the nature and extent of solar activity of this type, and its effects on the atmosphere, were not understood when Skylab was being designed and deployed. Indeed, understanding this set of phenomena was a contribution made by Skylab science. Had Skylab been launched after, rather than before, this was better…

    by Adrián Ponce-Alvarez, Biyu J. He, Patric Hagmann, Gustavo Deco How a stimulus or a task alters the spontaneous dynamics of the brain remains a fundamental open question in neuroscience. One of the most robust hallmarks of task/stimulus-driven brain dynamics is the decrease of variability with respect to the spontaneous level, an effect seen across multiple experimental conditions and in brain signals observed at different spatiotemporal scales. Recently, it was observed that the trial-to-trial variability and temporal variance of functional magnetic resonance imaging (fMRI) signals…

Recent work focuses on principles that constrain how vessel size changes through branching generations from the aorta to capillaries and uses scaling exponents to quantify these changes. Prominent scaling theories predict that combinations of these exponents explain how metabolic, growth, and other biological rates vary with body size. Nevertheless, direct measurements of individual vessel segments have been limited because…

  • Dominance of Deleterious Alleles Controls the Response to a Population Bottleneck

    by Daniel J. Balick, Ron Do, Christopher A. Cassa, David Reich, Shamil R. Sunyaev Population bottlenecks followed by re-expansions have been common throughout history of many populations. The response of alleles under selection to such demographic perturbations has been a subject of great interest in population genetics. On the basis of theoretical analysis and computer simulations, we suggest that this response qualitatively depends on dominance. The number of dominant or additive deleterious alleles per haploid genome is expected to be slightly increased following the bottleneck and…

  • Serine Phosphorylation of HIV-1 Vpu and Its Binding to Tetherin Regulates Interaction with Clathrin Adaptors

    Tonya Kueck et al.
    28 Aug 2015 | 2:00 pm
    by Tonya Kueck, Toshana L. Foster, Julia Weinelt, Jonathan C. Sumner, Suzanne Pickering, Stuart J. D. Neil HIV-1 Vpu prevents incorporation of tetherin (BST2/ CD317) into budding virions and targets it for ESCRT-dependent endosomal degradation via a clathrin-dependent process. This requires a variant acidic dileucine-sorting motif (ExxxLV) in Vpu. Structural studies demonstrate that recombinant Vpu/tetherin fusions can form a ternary complex with the clathrin adaptor AP-1. However, open questions still exist about Vpu’s mechanism of action. Particularly, whether endosomal degradation and…

  • Mitochondrial Activity and Cyr1 Are Key Regulators of Ras1 Activation of C. albicans Virulence Pathways

    Nora Grahl et al.
    28 Aug 2015 | 2:00 pm
    by Nora Grahl, Elora G. Demers, Allia K. Lindsay, Colleen E. Harty, Sven D. Willger, Amy E. Piispanen, Deborah A. Hogan Candida albicans is both a major fungal pathogen and a member of the commensal human microflora. The morphological switch from yeast to hyphal growth is associated with disease and many environmental factors are known to influence the yeast-to-hyphae switch. The Ras1-Cyr1-PKA pathway is a major regulator of C. albicans morphogenesis as well as biofilm formation and white-opaque switching. Previous studies have shown that hyphal growth is strongly repressed by mitochondrial…
  • The Activation of Phytophthora Effector Avr3b by Plant Cyclophilin is Required for the Nudix Hydrolase Activity of Avr3b

    Guanghui Kong et al.
    28 Aug 2015 | 2:00 pm
    by Guanghui Kong, Yao Zhao, Maofeng Jing, Jie Huang, Jin Yang, Yeqiang Xia, Liang Kong, Wenwu Ye, Qin Xiong, Yongli Qiao, Suomeng Dong, Wenbo Ma, Yuanchao Wang Plant pathogens secrete an arsenal of effector proteins to impair host immunity. Some effectors possess enzymatic activities that can modify their host targets. Previously, we demonstrated that a Phytophthora sojae RXLR effector Avr3b acts as a Nudix hydrolase when expressed in planta; and this enzymatic activity is required for full virulence of P. sojae strain P6497 in soybean (Glycine max). Interestingly, recombinant Avr3b produced…
  • Inhibition of mTORC1 Enhances the Translation of Chikungunya Proteins via the Activation of the MnK/eIF4E Pathway

    28 Aug 2015 | 2:00 pm
    by Pierre-Emmanuel Joubert, Kenneth Stapleford, Florence Guivel-Benhassine, Marco Vignuzzi, Olivier Schwartz, Matthew L. Albert Chikungunya virus (CHIKV), the causative agent of a major epidemic spanning five continents, is a positive stranded mRNA virus that replicates using the cell’s cap-dependent translation machinery. Despite viral infection inhibiting mTOR, a metabolic sensor controls cap-dependent translation, viral proteins are efficiently translated. Rapalog treatment, silencing of mtor or raptor genes, but not rictor, further enhanced CHIKV infection in culture cells. Using…

  • Do Insect Populations Die at Constant Rates as They Become Older? Contrasting Demographic Failure Kinetics with Respect to Temperature According to the Weibull Model

    Petros Damos et al.
    28 Aug 2015 | 2:00 pm
    by Petros Damos, Polyxeni Soulopoulou Temperature implies contrasting biological causes of demographic aging in poikilotherms. In this work, we used the reliability theory to describe the consistency of mortality with age in moth populations and to show that differentiation in hazard rates is related to extrinsic environmental causes such as temperature. Moreover, experiments that manipulate extrinsic mortality were used to distinguish temperature-related death rates and the pertinence of the Weibull aging model. The Newton-Raphson optimization method was applied to calculate parameters for…

  • From a Somatotopic to a Spatiotopic Frame of Reference for the Localization of Nociceptive Stimuli

    Annick L. De Paepe et al.
    28 Aug 2015 | 2:00 pm
    by Annick L. De Paepe, Geert Crombez, Valéry Legrain To react efficiently to potentially threatening stimuli, we have to be able to localize these stimuli in space. In daily life we are constantly moving so that our limbs can be positioned at the opposite side of space. Therefore, a somatotopic frame of reference is insufficient to localize nociceptive stimuli. Here we investigated whether nociceptive stimuli are mapped into a spatiotopic frame of reference, and more specifically a peripersonal frame of reference, which takes into account the position of the body limbs in external space, as…
  • Estimating Body Composition in Adolescent Sprint Athletes: Comparison of Different Methods in a 3 Years Longitudinal Design

  • Confidence in parenting could help break cycle of abuse

    29 Aug 2015 | 9:38 am
    To understand how confidence in parenting may predict parenting behaviors in women who were abused as children, psychologists have found that mothers who experienced more types of maltreatment as children are more critical of their ability to parent successfully. Intervention programs for moms at-risk, therefore, should focus on bolstering mothers' self-confidence -- not just teach parenting skills, the researchers said.

    Generally speaking, men and women seem value money differently. After surveying 100,000 British men and women about their feelings surrounding money, researchers found women were twice as likely to associate cash with love and feelings of care in general, while men were again twice as likely to equal money with freedom and power.

    29 Aug 2015 | 3:49 am
    For girls about to have their first period in rural India, menstruation can change their lives for the worst. Unable to afford disposable pads and tampons, girls often use rags which they reuse risking all sorts of health complications due to lack of sanitation. Many also decide to drop out of school out of fear that their rags might show or leak blood. “A fear of staining their clothes and being teased or humiliated about it by their male classmates seems to be a major reason of girls themselves choosing to miss their classes,” Maria Fernandez Ruiz de Larrinaga, communications specialist…

    by Kaylee Gund Hi all, Stego the Stegosaurus here, putting my best plate forward for the beginning of the school year! Stego the Stegosaurus, team leader for the field trips department. I was chatting with my Discovery Guide pals the other day and we’re all looking forward to the great school field trips we see every year. But surprisingly, a few local teachers they’ve spoken to are intimidated by the prospect of planning a field trip. I have to admit, the idea of taking more than 500 students off campus and bringing them back in one piece does sound overwhelming, but here at…

    Guest Contributor
    23 Aug 2015 | 4:00 am
    by Victoria Smith When my children were younger, and I was hip to the toddler scene, I would schedule play dates at all the usual places: I’d push the stroller to the park, load up the red wagon for the zoo, and slip Cheerios to fussy babies during story time at the library. The Houston Museum of Natural Science was also on the top of my list, and I was surprised other moms thought their kids were too young to appreciate it. “Oh, no! He’s after us!” The museum is fantastic for small kids! It’s got air conditioning, wide spaces to navigate, and if you have a two-year old…

    Tom Williams, my father-in-law, is a retired oil prospector who has a fascination with all things science and engineering. As such, he always gets me gifts for birthdays and holidays that he thinks will benefit me in my work (scientific texts, gadgets, etc). Last May, he gave me a fairly high-tech game trail camera with mounting attachment. This was delivered to my old study site (now new again?) in the Peruvian Amazon, by Ron Rossi, a Science Technology instructor from Michigan who spends a lot of time at the Amazon Explorama Lodges, just as I used to many years ago… In fact, today Ron…

    It’s a familiar scene: while outside city streets bake under the August sun, inside office buildings, workers, most of them women, are bundled in sweaters and blankets. But if this is such a universal experience, why do office buildings set their thermostats so low during the summer? There may be a scientific explanation for it.The journal Nature Climate Change recently published a study claiming that office building temperatures are based on the metabolic rates of men, who create and retain more heat on average than women. The temperature model, developed in the 1960s, also assumes that…

    Andrew Maynard

    In this age of public outrage and social media shaming, small acts of private kindness sometimes don’t seem to count for that much.  Yet even though they may not have the social cachet of jumping on the hashtag du jour, to the individual who receives them, they can still mean a lot.

  • Can public engagement stunt academic careers?

    Andrew Maynard
    11 Jul 2015 | 7:55 am
    As an academic, I take public engagement seriously.  I see it as a responsibility that comes with the societally-sanctioned license to study the things that I’m passionate about.  And I consider it a privilege to interact with others who can inform what I do as well as potentially benefitting from it.  Yet I’d be the first to admit that engaging with non-academics isn’t exactly a badge of honor within the hallowed halls of academia. Mostly, this feeling that spending time talking with and listening to people who aren’t academically “institutionalized”…

    On May 29th, there were 52,000 nanoparticles per cubic centimeter of air measured at the top of the Eiffel Tower. This may not seem the most compelling opening to an article, until you realize that the measurement was made in 1889 - over 100 years before nanotechnology and nanoparticles began hitting headlines as one of the most talked about emerging technologies in recent decades. The particles were measured by the Scottish scientist John Aitken, using his newly developed device for counting airborne dust particles.

    2 Jul 2015 | 5:03 pm
    Do you remember Cold Fusion? Remember when electrochemists Martin Fleischmann and Stanley Pons claimed to have achieved nuclear fusion in a bottle on a table in their lab in Utah? That was so 80s! Cold Fusion was quickly debunked and, apart from its appearance in a 1997 Val Kilmer Movie (The Saint), most people forgot about it. So it may surprise you to hear that Cold Fusion research continues to this day, with some “interesting” participants and some extraordinary and surprisingly persistent claims. The most recent International Conference on Cold Fusion (ICCF-19) was the largest yet…

It is very simple - grab a clear cup (or bottle or vase or flask), fill it about a third full of water and two thirds full of oil. The oil floats on the water as it has a lower density. Add some food colouring (you can do this at the start directly to the water, or after you have added the oil - this has the added benefit of showing that the food colouring does not dissolve in the…

    29 Aug 2015 | 7:50 am
    NASA has selected the potential next destination for the New Horizons mission to visit after its historic July 14 flyby of the Pluto system. The destination is a small Kuiper Belt object (KBO) known as 2014 MU69 that orbits nearly a billion miles beyond Pluto. This remote KBO was one of two identified as potential destinations and the one recommended to NASA by the New Horizons team. Although NASA has selected 2014 MU69 as the target, as part of its normal review process the agency will conduct a detailed assessment before officially approving the mission extension to conduct additional…
  • Harvard-Smithsonian CfA: "Did Life Spread Like an Epidemic Across the Vast Gulf of Interstellar Space?"
    29 Aug 2015 | 7:50 am
    We only have one example of a planet with life: Earth. But within the next generation, it should become possible to detect signs of life on planets orbiting distant stars. If we find alien life, new questions will arise. For example, did that life arise spontaneously? Or could it have spread from elsewhere? If life crossed the vast gulf of interstellar space long ago, how would we tell? New research by Harvard astrophysicists shows that if life can travel between the stars (a process called panspermia), it would spread in a characteristic pattern that we could potentially identify.

  • Cosmic Collision Triggers Rebirth of a "Radio Phoenix"
    28 Aug 2015 | 7:31 am
    Astronomers have found evidence for a faded electron cloud "coming back to life," much like the mythical phoenix, after two galaxy clusters collided. This "radio phoenix," so-called because the high-energy electrons radiate primarily at radio frequencies, is found in Abell 1033. The system is located about 1.6 billion light years from Earth. By combining data from NASA's Chandra X-ray Observatory, the Westerbork Synthesis Radio Telescope in the Netherlands, NSF's Karl Jansky Very Large Array (VLA), and the Sloan Digital Sky Survey (SDSS), astronomers were able to recreate the scientific…

    A team of international scientists has shown for the first time that galaxies can change their structure over the course of their lifetime. By observing the sky as it is today, and peering back in time using the Hubble and Herschel telescopes, the team have shown that a large proportion of galaxies have undergone a major 'metamorphosis' since they were initially formed after the Big Bang. By providing the first direct evidence of the extent of this transformation, the team hope to shed light on the processes that caused these dramatic changes, and therefore gain a greater understanding of the…

    The Microcystis cyanobacteria bloom centralized around Lake Erie’s western shores has started to spread into its central basin, according to a bulletin released by the National Oceanic and Atmospheric Administration. Southwesterly winds pushed the bloom northward along Michigan’s coast, the bulletin reads. From there, it began to extend into the central basin at a point halfway between Cleveland and Rondeau, Ontario. The development comes as scientists around the lake are concerned that forecasts for this summer’s bloom may have underestimated its severity. Unexpected amounts of…

    Astrobiologist Jacob Haqq-Misra likes to ask questions about our future in space. If you’ve been following this blog for a long time and the name seems familiar, it’s because you’ve read a take on a paper regarding the Fermi Paradox he co-authored. But this time, instead of looking at the dynamics of an alien civilization in the near future, he turned his eye towards ours by asking if it would be beneficial for astronauts we will one day send to Mars to create their own government and legally become extraterrestrial citizens from the start. At its heart, it’s not a…

    Unless you live under a rock on an alien planet, you probably know all about the massive hacks which successfully revealed every digital asset used to run Ashley Madison, the much maligned, famous dating site for cheating spouses. And you probably also know of several very vocal and visible morality crusaders in the U.S. and Europe, who have been outed as long term members paying hundreds of dollars to guarantee having affairs. A top notch cybersecurity reporter with trusted sources in the web’s seedy underbelly, Brian Krebs, has already found evidence that an enterprising group of…

    You probably know that H.P. Lovecraft was not known for his health, wealth, progressive views, or success in life, In fact, anything positive that happened to the man took place long after he’d been buried in obscurity. Today we know him as the creator of the sci-fi horror genre, a classic inspiration for ancient alien theories as we know them today, and yes, a virulent racist who had immense distaste for anyone who was not a white, male, wealthy Protestant with English roots, and drew on it to create alien monsters who ignored his protagonists at best, or would pray on them with a…

We know a lot about them, including how many of them form. Enormous halos of dark matter and gas collapse into a massive black hole that consumes the matter spiraling around it, producing a bright quasar that takes eons to cool off and settle into a quiet, normal, mature galaxy that prefers a nice nap to a billion year rave under the blazing light of superheated plasma, and has a diversified portfolio of stars that will…

From the time I had my first toy glockenspiel and a miniature guitar, through the time my little sister decided she didn’t want to learn to play guitar and I was riff happy to take the axe off her hands (still got it along with a few additions in the intervening four decades or so) to the present day and my deluded attempts to reinvent my…

      Thanks to Taro Gomi, we all know that everybody poops. Poop contains a lot of interesting stuff including tons of microbes, like bacteria. Depending on our own health, our poop can harbor both helpful and harmful microbes. And as a result, poop can spread disease. So where do microbes in poop come from? Poop is a waste product formed in our intestines during digestion. Lots of different species of bacteria and other microscopic organisms like fungi and yeast live in our gut and they help our bodies break down food, make vitamins (like vitamin B and K), and fend off harmful bacteria.

  • ‘Trojan Horse’ of immune system revealed

    28 Aug 2015 | 12:00 am
    Human cells use viruses as a ‘Trojan Horse’ to transport a messenger that encourages the immune system to fight the viral infection. A research team at Oxford University studied the detection of a virus after it enters a cell in the body by a protein known as cGAS. They discovered that as part of this mechanism, as some viruses replicate within the cell they incorporate cGAMP – a signalling molecule that activates the immune system – which can prompt an immune response. “We hypothesised that as the virus replicated; cGAMP was incorporated and carried to the next cell to be infected.

We enjoy marching bands and synchronized swimming, and we are particularly entranced by our cousins in the animal world. A murmuration of starlings, for example, can be mesmerizing. Inevitably, no matter what we’re watching, the same question comes to mind: how do animals know which way to go when moving en masse? Or, better yet, how do they not all crash into one another? It’s an important question, because many animals move in groups, and in cases where…

So it’s with great pleasure today that I write a citizen science post on her favorite subject.

Project: iSeeChange: The Almanac For decades, anyone who relies on the weather for a living has depended on almanacs, those annual calendars with weather statistics and tables, to roughly predict the current weather. But with climate change making patterns harder and harder to suss, a new project called iSeeChange wants you to help document what’s going on to create a living almanac. Started by Julia Kumari Drapkin at the Colorado public station KVNF, the project is going nation wide, and is designed to combine citizen science,…

    26 Aug 2015 | 8:18 am
    You can tell how old a tree is by counting its rings, but those rings have a lot more to say. And if you live in California, which is in the midst of a four-year drought, you may want to listen.Dan Griffin — the subject of “Tree Hunter,” directed by Jamie Schutz — uses trees as history books. He studies their past precipitation patterns and uses that information to forecast future precipitation and advise California water management officials. This film is part of “The Collectors,” a series of short documentaries from FiveThirtyEight and ESPN Films.

    Inside every star that shines, there’s a continual tug-of-war of wills—between the outward push of its fusion and the inward pull of its own gravity. No one wins. But once all its hydrogen has burned into helium, the gravitational force, now having no opposition, squeezes the star to its end. A star with a mass less than 1.4 solar masses goes out as a “white dwarf,” a stellar corpse about the size of the Earth, but astonishingly dense. A teaspoon of this remnant would hold the mass of a car. (Solar mass is the unit of expressing the mass of stars, galaxies, and other celestial…

    By Anupum Pant Nitrogen tri-iodide (NI3) is a contact explosive. It’s like nitroglycerin but much more sensitive than that. Unlike nitroglycerin, this doesn’t require to be hit by a hammer to explode. That means, the compound is so unstable that even a slight touch will make it explode. It’s so sensitive to disturbance that a mosquito flying off of this powder will detonate it. Here’s a demonstration in the video below… Now one thing that comes to mind when you see something like this is that how must have the person in this video handled it and put it on paper.

This is usually a column of wax which is icky to look at, consists of fibers and is pretty rigid. It might look like a roughed up candle to an untrained eye. Also, these ear wax columns can be as much as 1 to 4 feet in height. But all of that is not even the most interesting thing about whale’s earwax.

Now, take this plot and spin it fast with the x axis as the axis of rotation. You’ll then have a horn shaped solid object which is endlessly long. A mathematical object also known as the Gabriel;s horn or Torricelli’s trumpet. Mathematically, this object is interesting because it can contain a finite amount of volume, but it’s surface area is infinite. That is to say, you can fill the horn/trumpet with a finite amount of paint, yet the…

    What I’ve Learned: “I’m the lysosome. I solve subcellular problems.” Everybody has a mess that needs cleaning up, and you usually know who to call to get it taken care of. If you’re staring at the crumby remnants of your BLT, you call the waiter. If the backseat of your car is dirty, you call an auto detailer. (Or, if the backseat of your car is really dirty, you call Harvey Keitel.) And if your cell is getting cluttered full of junk, you call the “cleaner” of the microscopic world: the lysosome. Lysosomes are basically emergency cleaning supplies…
  • Noble Gases

    16 Aug 2015 | 8:59 pm
    What I’ve Learned: “Noble gases: They are SO not into you.” When you hear the word noble, it conjures many thoughts. French aristocracy. Those starch-shirted tea-sippers on PBS. “Barnes and”. But what is it exactly that these “noble” things have in common? For starters, they really don’t like dealing with people. They’re not into sharing or helping or customer service. Or customers. Or anyone they consider peasants. Which is all of us. But this notion of noble isn’t limited to the Antoinettes and booksellers and creepy Crawleys of…
  • Zombie Computer

    9 Aug 2015 | 8:35 pm
    What I’ve Learned: “Zombie computer: beware the night of the living Dells.” Zombies are kind of a big deal these days. If you’re a fan of TV or movies or video games, you’ve surely seen them — and like actual zombies, they’re still multiplying. It’s like somebody ran a zombie through a Dr. Seuss-ifier: You’ve got fast ones and slow ones and now one with an ‘i’. They crave brain, feel no pain and just want you to die. There are zombies that walk and zombies that talk and zombies that grin like Fairuza Balk. Some zombies dance…

    22 Aug 2015 | 11:55 pm
    Window view from my (intended) home in Marseille. I’m moving from Germany to France. This is my goodbye to the place that welcomed me for five years. You may be missing the Much Bigger Outside after three weeks without any new posts. Not that I didn’t write. Indeed, I wrote a post a couple of weeks ago. However, when Carla read the draft (she always does), she said I would stir the wrath of the gods at me if I published it. Since I don’t like to be beneath the wrath of anyone, I cowardly acquiesced and self-censored its publication. Sorry, no cookies. But the main reason I…
  • Two Things Papers Don’t Show, but Should

    25 Jul 2015 | 11:27 pm
    Negative results and reproducibility, although central in science, are neglected by scientific publications. We urgently need specialized journals to deal with them. 1. Negative Results A good colleague and friend of mine—for privacy let’s fictionally call him Oliver—has a problem: his simulations don’t match the experiments. For months, he and his team worked on the computational simulations of a certain molecule. He did, as usual, a high-level and serious research. By the end, however, Oliver found out that the results of his simulations were exactly the opposite of the…

  • The Tim Hunt’s Regret Rule

    Mario Barbatti
    28 Jun 2015 | 2:38 am
    With the Web, an ill-shaped comment or a bad-taste joke may bring disproportional shame and destroy lives. We urgently need to learn how to survive in these dangerous times.  In the beginning, words had the weight of dust: they floated in the air and disappeared before anybody noticed them. And then the Men said “Let there be the Web,” and there was the Web. The Men thought that the Web was good, as it fed them with the knowledge of good and evil. But the Web turned to the Men and said “I will give you the knowledge of good and evil, but in return I will also carve on…

    #StopTheBells Why do secular democracies still allow church bells to be a pain in the ass, invading and disturbing people’s private lives? Which part of the lesson on religion-state separation they didn’t get? It’s always the same: you wake up early for work and still drowsy promise yourself that in the next weekend you’re going to sleep till the cows come home. Well, I do make such a promise every working day. However, since I moved over five years ago to Mülheim, a small town in west Germany, I could never keep it. The thing is that about 1 km from my home there are two…

  • Nitrogen Triiodide Is So Unstable That Mosquito Landing On It Explodes

    28 Aug 2015 | 8:33 pm
    Nitrogen Triiodide (NI3) is a highly unstable inorganic compound that explodes when disturbed. Because of its ultra sensitive contact explosive characteristics, this substance will explode even when we apply a relatively small quantities of energy, whether it be heat, light, sound and physical pressure such as light touch or when tiny insects like ants, mosquitoes land on it. The video, Slow Motion Contact Explosive – Nitrogen Triiodide, released by the Royal Institution demonstrates the volatility of Nitrogen Triiodide. Nitrogen Triiodide (NI3) is basically prepared by reacting iodine…
  • Stop Hating Yourself: A 5-Step Guide To Overcome Self-Hatred

    24 Aug 2015 | 12:37 am
    While talking about self-hatred it is the younger generation which is greatly affected by it. According to the recent statistics, there were more than 3,000 adolescent girls and boys who think they are not good enough and are not measuring up in terms of their looks, personal relationships and academic performance. And, this group of people was only found with low self-esteem and involved in negative activities like smoking, drinking, bullying and so on. Actually, this type of discouraging outlook is the result of two types of influences. How we form our self-perception entirely depends upon…
  • 3D Printing With Glass Breakthrough By MIT Scientists

    23 Aug 2015 | 8:16 pm
    Scientists at the Massachusetts Institute of Technology have unveiled a new system of 3D printing using optically transparent glass, instead of plastic. As researchers described, the process of printing is known as Glass 3D Printing (G3DP) and it works basically the same way as the conventional 3D printing. It can control light transmission, reflection and refraction and even modulate transparency, color variation and thickness of the print. This system of 3D printing with glass is based on a dual heated chamber concept (placed above one another). The upper chamber, which acts as a Kiln…
  • How Moral Behavior Influences Our Identity To People With Alzheimer’s Disease

    19 Aug 2015 | 10:19 pm
    Moral behavior is a conduct mainly concerned with the code of interpersonal behavior that is regarded right or acceptable in a particular society or community. Moral sensitivity, moral motivation, moral judgment and moral character are the four components of moral behavior. All these four components individually do at least have something to do with our personality, but moral behavior, as a whole, is a core component of our identity.   According to new study, memory is not something that shapes us who we are but it is the moral behavior which is the most important indicator of our…
  • Meet The World’s Oldest Living Cat, Corduroy, Who Is 26

    14 Aug 2015 | 10:18 pm
    Guinness World Records has crowned Corduroy, an Oregon cat, as the oldest living cat in the world at 26 years and 13 days. Corduroy was born on August 1, 1989. Ashley Reed Okura, the owner of the feline, said she was only seven when Corduroy first entered her life. Considering the average lifespan of a domesticated cat which is typically 15 – the age of Corduroy, that is 26, is pretty impressive. “The secret has been allowing him to be a cat – hunting and getting plenty of love,” Reed Okura said in a statement at Reuters. Aside from cat’s inborn instinct of…

    Saber toothed tigers are some of the most famous and plentiful prehistoric fossils found today, yet little is known about how they actually lived. Sabers, also known by their scientific name Smilodon fatalis, are second only to the dire wolves as the most common animal found in the La Brea Tar pits in Los Angeles, California. Other species of saber toothed cats existed all over the world, but this particular species of the big cat prowled the southwestern United States until about 10,000 years ago. Smilodon and its relatives are most famous for their massive fangs that can stretch to a length…
  • New Canadian Dinosaur Causes Scientists to Rethink Ceratopsian Evolution

    The mighty Triceratops has always captivated young and old alike. His three massive horns and magnificent crowned frill make him a favorite for many dinosaur lovers. What many people might not realize is that the Triceratops is only one of several species of ceratopsians that have been discovered, and certainly among hundreds that have evolved throughout prehistoric times. In 2010, a new Canadian bone bed was being excavated, and over the course of four years several specimen were uncovered. The most astonishing part was that a species of ceratopsian entirely unknown to science came with it.

    A groundbreaking new study1 suggests that companies need to offer a fair deal to their employees to survive. The study followed the fate of 136 companies over a five-year period, starting from the time that they initiated their public offering on the U.S. Stock market. The management practices of the companies were coded using information available from their offering prospectuses, which were publicly available. Statistically controlling for other factors, companies that placed a high value on human resources and shared profits with employees had a much higher survival rate over a five-year…
  • Paleontology’s Strangest Fossil Finally Explained

    Hallucigenia sparsa doesn’t sound like an organism you’d be familiar with. In fact, even upon seeing this sea-dwelling creature, many people, scientists included, couldn’t tell its top from its bottom. This small, worm-like creature is a 500 million-year-old Cambrian Explosion fossil originally described in 1977 by Conway Morris, a paleontologist best known for his work in the Burgess Shale. Finally, decades later in 2014, scientists figured out which end was the head and on what side it stood. Then they started the process of discovering the worm’s descendants. As it turns out, this…

We are such a cultural species that all of us, without exception, see the world through socially constructed lenses (the left half of the Kosmos). Our worldviews might attempt to represent external reality (science) or they might be elaborately otherworldly (religion). They exist inside our heads (the upper left quadrant) but also require a collective expression (the lower left quadrant). An infinitude of socially constructed…

  • Primary Colors: Why One Set Wouldn't Suffice

    24 Aug 2015 | 12:07 am
    Colors are a ubiquitous fact of human life. Imagine a world without colors; all of the great masterpieces would be painted in gray scale, that potato could be purple or brown and there would be no more blue skies. Experientially, we are highly familiar with the concept of colors, but I would say it isn’t common to understand the more technical side of the world of colors. Let’s explore this more analytical side and it’s applications as we try to answer a question most of us have probably had: why are there multiple sets of primary colors?At the most basic, colors are categories of light…
  • Why Cold Drinks "Sweat"

    With a horrible heat wave hitting the Philadelphia area, it’s good to think cool thoughts. Already feeling the heat last night, I left a coconut water in the freezer with the intent to drink it but forgot and so took it to work this morning frozen solid. I figured since it’s so hot outside and the metal can is a good conductor, it’d probably melt pretty quickly. And while the ice in immediate contact did melt, the inside remained frozen and I had to cut the top open with scissors to eat it. Before I figured this out, the can had already shed a puddle at my desk. Have you ever wondered…
  • The Fun of Latin and Ballroom Dancing Explained with Mechanics

    13 Aug 2015 | 9:38 pm
    Last semester, I picked up Latin and ballroom dancing as a hobby. All through high school I didn’t dance, but thanks to the recommendation of a friend I decided to go to free introductory dance lessons. At first it was just fun to socialize, learn some new steps and practice body coordination, but I soon grew to love it. Our Latin dance teacher has a particular habit of describing dance movements in terms of coordinates and physics; rumba walks require your center of mass over your front foot for balance and look best if you extend the axis running from your shoulder to opposite leg as far…

    I have a question for you. We use the stuff all the time, but do you really know what plastics are? I mean really know. I definitely didn't until this past year when I took a course on materials science that covered the nature of polymers beyond what is traditionally taught about just joining a bunch of monomers together into strings. So let’s take a closer look at a material that has revolutionized the modern age. Plastic is a broad term for a number of synthetic polymers with varying structures, properties, origins and chemical compositions. The properties of plastics vary according to…
