    Most people know that drinking and driving is incredibly dangerous. Its reputation as a major risk has been cemented through the preventable deaths of thousands of people and years of education and awareness efforts. But it turns out—drugged driving is a major problem too. A recent study found that more high school seniors and college students that drove impaired or with an impaired driver were under the influence of marijuana, not alcohol. The study also found that drugged drivers are more likely to have car accidents and traffic tickets or warnings. But it’s not just dents to your car…

    By Anupum Pant At school we were expected to remember things. Every single piece of misplaced information in your brain costed you points  in tests. You couldn’t afford to forget – The very mental pressure which caused panic and made you forget things! Turns out, there is a forgetting protein in our brains called Musashi. It messes with the way nerve cells in the brain communicate with each other – basically makes you forget stuff. Scientists have, genetically modified ringworms to clear Musashi off their brains. As expected, the Musashi free ringworms remembered things…

  • Does stigma keep same-sex couples from talking about abuse?

    Nora Dunne-Northwestern
    19 Sep 2014 | 8:53 am
    Domestic violence occurs at least as frequently, and likely even more so, between same-sex couples, but researchers suspect it may often go unreported because of the stigma attached to sexual orientation. When analyzed together, previous studies indicate that domestic violence affects 25 percent to 75 percent of lesbian, gay, and bisexual people. However, the lack of representative data and under-reporting paints an incomplete picture of the true landscape, suggesting even higher rates.

  • Berry extract added to chemo kills pancreatic cancer

    U. Southampton
    19 Sep 2014 | 8:32 am
    A chemotherapy drug was more effective at killing pancreatic cancer cells when an extract from chokeberries was added to the mix. Chokeberry is a wild berry that grows on the eastern side of North America in wetlands and swamp areas. The berry is high in vitamins and antioxidants, including various polyphenols—compounds that are believed to mop up the harmful by-products of normal cell activity. The researchers chose to study the impact of the extract on pancreatic cancer because of its persistently dismal prognosis: less than 5 percent of patients are alive five years after their…

  • Will ‘VIP’ protect us from the flu and HIV and malaria?

    Kimm Fesenmaier-Caltech
    19 Sep 2014 | 7:46 am
    Efforts to develop broadly effective vaccines for HIV and malaria have had limited success. Now scientists are testing a totally different approach—one that so far seems very promising. Unlike vaccines, which introduce substances such as antigens into the body hoping to illicit an appropriate immune response, the new method provides the body with step-by-step instructions for producing specific antibodies shown to neutralize a particular disease. The method is called vectored immunoprophylaxis, or VIP. The technique was so successful in triggering an immune response to HIV in mice that it…
  • Scientists use light to make mice asocial

    Jessica Stoller-Conrad - Caltech
    19 Sep 2014 | 6:18 am
    Scientists have discovered antagonistic neuron populations in the mouse amygdala that control whether the animal engages in social behaviors or asocial repetitive self-grooming. This discovery may have implications for understanding neural circuit dysfunctions that underlie autism in humans. Humans with autism often show a reduced frequency of social interactions and an increased tendency to engage in repetitive solitary behaviors. Autism has also been linked to dysfunction of the amygdala, a brain structure involved in processing emotions. Social or asocial? This discovery, which is like a…

    Breast cancer experts around the world have issued a plea to researchers, academics, drug companies, funders and advocates to carry out high quality research and clinical trials for advanced breast cancer, a disease which is almost always fatal and for which there are many unanswered questions. In the latest international consensus guidelines for the management of advanced breast cancer, published simultaneously in the leading cancer journals The Breast and Annals of Oncology [1] today (Friday), the experts say that further research and clinical trials are "urgently needed" to find the best…

    The sense of fairness did not evolve for the sake of fairness per se but in order to reap the benefits of continued cooperation, so say Frans de Waal, PhD, and Sarah Brosnan, PhD, co-authors of a review article about inequity aversion (IA), which is defined as a negative reaction to unequal outcomes. The review is published in Science. Their conclusion comes after the co-authors reviewed more than 35 IA-related studies to address their hypothesis that it is the evolution of forestalling partner dissatisfaction with obtained outcomes and its negative impact on future cooperation that allowed…
  • Milestone In Chemical Studies Of Superheavy Elements

    An international collaboration led by research groups from Mainz and Darmstadt, Germany, has achieved the synthesis of a new class of chemical compounds for superheavy elements at the RIKEN Nishina Center for Accelerator-based Research (RNC) in Japan. For the first time, a chemical bond was established between a superheavy element – seaborgium (element 106) in the present study – and a carbon atom. Eighteen atoms of seaborgium were converted into seaborgium hexacarbonyl complexes, which include six carbon monoxide molecules bound to the seaborgium. Its gaseous properties and adsorption to…
  • Environmental Pollutants Make Worms Susceptible To Cold

    21 Sep 2014 | 9:26 am
    Imagine you are a species which over thousands of years has adapted to the arctic cold, and then you get exposed to a substance that makes the cold dangerous for you. This is happening to the small white worm Enchytraeus albidus, and the cold provoking substance, called nonylphenol, comes from the use of certain detergents, pesticides and cosmetics. Nonylphenol is suspected of being a endocrine disruptor, but when entering the worm it has another dangerous effect: It inhibits the worm's ability to protect the cells in its body from cold damage. read more

    UPDATE: To avoid confusion: eating lots of tomatoes will not stop you getting prostate cancer if other risk factors are in place! At least 20 years ago I wrote a news story in my rookie days about how the natural red pigment in tomatoes, the antioxidant lycopene, could somehow protect men against prostate cancer. Nothing was ever proven and the latest news which hit the tabloids in the last couple of weeks doesn’t add much, at least if you read between the lines. NHS Choices, as ever, has a good summary: “This large study has shown an association between the consumption of more…

    I have a new paper out in Frontiers in Psychology: The perspectival shift: how experiments on unconscious processing don’t justify the claims made for them. There has been ongoing consternation about the reliability of some psychology research, particularly studies which make claims about unconscious (social) priming.

This is the fourth book in the Jumper series (not counting the movie tie-in novel), and ordinarily wouldn’t be worth much of a review, because if you haven’t read the first three, this book won’t make a lick of sense. If you have read the others, it’s a worthy sequel, but three earlier books makes for a lot of backstory to explain in writing the book up. It’s worth noting, though, because it belongs to a sort of unofficial subgenre: books about Working Things Through.

Using a unique set of North Dakota leaf fossil assemblages spanning 2.2 Myr across the event, we show among angiosperms a reduction of ecological strategies and selection for fast-growth strategies consistent with a hypothesized recovery from an impact winter. Leaf mass per area (carbon investment) decreased in both mean and variance, while vein density (carbon…

  • Examining Variable Domain Orientations in Antigen Receptors Gives Insight into TCR-Like Antibody Design

    James Dunbar et al.

    by James Dunbar, Bernhard Knapp, Angelika Fuchs, Jiye Shi, Charlotte M. Deane The variable domains of antibodies and T-Cell receptors (TCRs) share similar structures. Both molecules act as sensors for the immune system but recognise their respective antigens in different ways. Antibodies bind to a diverse set of antigenic shapes whilst TCRs only recognise linear peptides presented by a major histocompatibility complex (MHC). The antigen specificity and affinity of both receptors is determined primarily by the sequence and structure of their complementarity determining regions (CDRs). In…
  • Genome-Scale Metabolic Network Validation of Shewanella oneidensis Using Transposon Insertion Frequency Analysis

    Hong Yang et al.
    18 Sep 2014 | 2:00 pm
    by Hong Yang, Elias W. Krumholz, Evan D. Brutinel, Nagendra P. Palani, Michael J. Sadowsky, Andrew M. Odlyzko, Jeffrey A. Gralnick, Igor G. L. Libourel Transposon mutagenesis, in combination with parallel sequencing, is becoming a powerful tool for en-masse mutant analysis. A probability generating function was used to explain observed miniHimar transposon insertion patterns, and gene essentiality calls were made by transposon insertion frequency analysis (TIFA). TIFA incorporated the observed genome and sequence motif bias of the miniHimar transposon. The gene essentiality calls were…
  • A Systems Approach to Predict Oncometabolites via Context-Specific Genome-Scale Metabolic Networks

    Hojung Nam et al.
    18 Sep 2014 | 2:00 pm
    by Hojung Nam, Miguel Campodonico, Aarash Bordbar, Daniel R. Hyduke, Sangwoo Kim, Daniel C. Zielinski, Bernhard O. Palsson Altered metabolism in cancer cells has been viewed as a passive response required for a malignant transformation. However, this view has changed through the recently described metabolic oncogenic factors: mutated isocitrate dehydrogenases (IDH), succinate dehydrogenase (SDH), and fumarate hydratase (FH) that produce oncometabolites that competitively inhibit epigenetic regulation. In this study, we demonstrate in silico predictions of oncometabolites that have the…
  • Pupil-Linked Arousal Determines Variability in Perceptual Decision Making

    Peter R. Murphy et al.
    18 Sep 2014 | 2:00 pm
    by Peter R. Murphy, Joachim Vandekerckhove, Sander Nieuwenhuis Decision making between several alternatives is thought to involve the gradual accumulation of evidence in favor of each available choice. This process is profoundly variable even for nominally identical stimuli, yet the neuro-cognitive substrates that determine the magnitude of this variability are poorly understood. Here, we demonstrate that arousal state is a powerful determinant of variability in perceptual decision making. We measured pupil size, a highly sensitive index of arousal, while human subjects performed a…

  • Clonal Expansion of Early to Mid-Life Mitochondrial DNA Point Mutations Drives Mitochondrial Dysfunction during Human Ageing

    Laura C. Greaves et al.
    18 Sep 2014 | 2:00 pm
    by Laura C. Greaves, Marco Nooteboom, Joanna L. Elson, Helen A. L. Tuppen, Geoffrey A. Taylor, Daniel M. Commane, Ramesh P. Arasaradnam, Konstantin Khrapko, Robert W. Taylor, Thomas B. L. Kirkwood, John C. Mathers, Douglass M. Turnbull Age-related decline in the integrity of mitochondria is an important contributor to the human ageing process. In a number of ageing stem cell populations, this decline in mitochondrial function is due to clonal expansion of individual mitochondrial DNA (mtDNA) point mutations within single cells. However the dynamics of this process and when these mtDNA…
  • Interplay of dFOXO and Two ETS-Family Transcription Factors Determines Lifespan in Drosophila melanogaster

    Nazif Alic et al.

    by Nazif Alic, Maria E. Giannakou, Irene Papatheodorou, Matthew P. Hoddinott, T. Daniel Andrews, Ekin Bolukbasi, Linda Partridge Forkhead box O (FoxO) transcription factors (TFs) are key drivers of complex transcriptional programmes that determine animal lifespan. FoxOs regulate a number of other TFs, but how these TFs in turn might mediate the anti-ageing programmes orchestrated by FoxOs in vivo is unclear. Here, we identify an E-twenty six (ETS)-family transcriptional repressor, Anterior open (Aop), as regulated by the single Drosophila melanogaster FoxO (dFOXO) in the adult gut. AOP, the…

  • The Proprotein Convertase KPC-1/Furin Controls Branching and Self-avoidance of Sensory Dendrites in Caenorhabditis elegans

    Yehuda Salzberg et al.
    18 Sep 2014 | 2:00 pm
    by Yehuda Salzberg, Nelson J. Ramirez-Suarez, Hannes E. Bülow Animals sample their environment through sensory neurons with often elaborately branched endings named dendritic arbors. In a genetic screen for genes involved in the development of the highly arborized somatosensory PVD neuron in C. elegans, we have identified mutations in kpc-1, which encodes the homolog of the proprotein convertase furin. We show that kpc-1/furin is necessary to promote the formation of higher order dendritic branches in PVD and to ensure self-avoidance of sister branches, but is likely not required during…
  • A Genetic Assay for Transcription Errors Reveals Multilayer Control of RNA Polymerase II Fidelity

    Jordan D. Irvin et al.
    18 Sep 2014 | 2:00 pm
    by Jordan D. Irvin, Maria L. Kireeva, Deanna R. Gotte, Brenda K. Shafer, Ingold Huang, Mikhail Kashlev, Jeffrey N. Strathern We developed a highly sensitive assay to detect transcription errors in vivo. The assay is based on suppression of a missense mutation in the active site tyrosine in the Cre recombinase. Because Cre acts as tetramer, background from translation errors are negligible. Functional Cre resulting from rare transcription errors that restore the tyrosine codon can be detected by Cre-dependent rearrangement of reporter genes. Hence, transient transcription errors are captured…

    by John R. Gallagher, Doina Atanasiu, Wan Ting Saw, Matthew J. Paradisgarten, J. Charles Whitbeck, Roselyn J. Eisenberg, Gary H. Cohen Entry of herpes simplex virus (HSV) into a target cell requires complex interactions and conformational changes by viral glycoproteins gD, gH/gL, and gB. During viral entry, gB transitions from a prefusion to a postfusion conformation, driving fusion of the viral envelope with the host cell membrane. While the structure of postfusion gB is known, the prefusion conformation of gB remains elusive. As the prefusion conformation of gB is a critical target for…

    Naked Security has a nice roundup of reasons not to click any unsubscribe links in spam emails: The first is that by clicking the link you have confirmed to the spammer that the emai address they spammed is valid, which means they can spam you again or sell it on to other spammers as a validated address. Secondly, by “unsubscribing” you’re effectively telling the spammer that you actually opened their email…and so may be susceptible to more targeted spam later. Thirdly, if your unsubscribe goes back via email you’re sending all sorts of meta information about…

    19 Sep 2014 | 4:19 am
    Since the recession, it's taken a while for household incomes to come back to where they were in 2009. In most parts of the country, incomes are still lower, however, it appears they are making their way back to 2009 levels. With the Census Bureau's recent release of data from their American Community Survey, the Washington Post charted the annual difference from 2009 to 2013. Each line represents a metropolitan area's difference in household income of a current year, compared to that of 2009. So the closer to or higher above the thin black baseline the better.

Thus, some of the plastic in the South Atlantic “garbage gyre” was actually thrown away in nations bordering the Indian Ocean. Oceanographers have long known that currents converge on mid-ocean circulating structures called gyres. By email, Erik van Sebille, an oceanographer at the University of South Wales in Australia…

A lethal virus that causes uncontrolled bleeding and leaves patients and corpses highly contagious could not have chosen a more hospitable locale than the West African nations of Liberia, Sierra Leone, Guinea and Nigeria for its worst-ever outbreak.

They repeatedly asked my mom her name, her date of birth, what surgery she was there for and which side of her body doctors were supposed to operate on. All went well, but the experience reminded me of Atul Gawande’s 2007 New Yorker article (and 2009 book) about how using checklists could improve medical outcomes.

    While the art of reading hand poured sequencing gels is forgotten as the next generation sequencers spit out genome after genome, protein expression still often requires sweat, tears and a lot of luck. I think this happens not because there is something different about protein expression in comparison with sequencing, but because people do not think about protein expression as an engineering challenge. But where there is engineering, there should be a manual, right? Neither the literature reviews full of confusing technical details, nor protocols, which tell you how to do something but not…

    Although I say ‘taken for granted’, over the years of working in and managing microscope facilities, it quickly became clear that the position of the microscope, user position and set-up were aspects which were not considered by many users. These are fundamental points which not only take strain from your eyes, back and so on, but can improve your imaging. You are less likely to spend a long time searching slides for that perfect field of view if you are struggling to see details on your slide because of sunlight streaming through a window, or if you have back pain and neck strain.

    As with some of the greatest discoveries in science, from penicillin to microwave ovens and play-doh, PCR was discovered serendipitously. Thanks to the work of many scientists, including Watson and Crick, Kornberg, Khorana, Klenow, Kleppe (so many K’s…) and Sanger, all the main ingredients for PCR had been described by 1980. Like butter, flour, eggs, and sugar lined up on a kitchen table, the ingredients of PCR were waiting for someone to scream out “CAKE!” and open up the scientific community to a technique with a myriad of applications.

But when people feel they have no control over setbacks, a separate part of the brain determines whether or not the person persists.

  • New Trend Alert: Using Video to Introduce Data

    Emily Poulin
    3 Sep 2014 | 12:46 pm
    Here at BenchFly, we’re always looking for new ways to use video to improve scientific research. During a recent conference in Europe, the value of using video to simply introduce a research topic hit home with me. An exciting part of being a researcher of any level is the opportunity to travel to research conferences held all over the country and the world. However, the tricky part about a conference is that while the audience is typically knowledgeable about the general topic, there are so many contexts in which the specific topic can be covered. Do you work in animals? Cell culture? The…

    22 Aug 2014 | 8:00 am
    When we started BenchFly five years ago, in 2009, our mission was to make research a better career for current and future generations of scientists. Today we continue to work toward this goal using video as the primary means to educate scientists in companies, in universities and now in high schools! In the fall of 2013, we were incredibly fortunate to have met Kentucky teacher Tricia Shelton (thank you, Twitter!) arguably one of the most energetic, passionate, and dedicated teachers out there. In less than 12 months, our collaboration has resulted in a new video-based curriculum, called…
  • Pipetting with Your iPhone?

    16 Jul 2014 | 8:27 am
    “Set timer for ten minutes.” Instead of the kitchen timers the rest of us use, the post-doc sitting behind me regularly uses Siri to time his experiments. As it turns out, it’s actually easier to tell a computer to set a timer for you than to do it yourself, and Siri is quickly becoming our lab’s newest research assistant. With a new iPhone model out each year, it’s not hard to believe that we’ll soon have everything we need on the little 2¼” x 4¾” device we can no longer go anywhere without. But what does that mean for us lab rats? And how can we leverage new technology to…

    Ohio’s Buckeye Lake, home to a famous cranberry bog, has been beset by toxic algal blooms in recent years. The Ohio Department of Natural Resources has responded by spending $700,000 to attack the algae problem there since June 2011. Much study has taken place in and around Buckeye Lake since that time and many agree that increased nutrient levels in the lake’s water are feeding the algae. The question is: where are all the nutrients coming from? Buckeye Lake, May 2009. (Credit: Flickr User WorldIslandInfo.com via Creative Commons) To pinpoint some of the sources, officials with the…
  • Research Summary: Effects Of Nutrient Limitation On The Release And Use of Dissolved Organic Carbon From Benthic Algae In Lake Michigan

    Daniel Kelly
    10 Sep 2014 | 6:05 am
    In recent years, benthic macroalgae have become increasingly abundant in nearshore areas of the Laurentian Great Lakes, frequently forming nuisance blooms and mats of dead and decaying algae that harbor pathogens such as avian botulism and foul bathing beaches. This increase in macroalgae is thought to be due to increased nutrient concentrations and light levels reaching the bottom because of invasive dreissenid mussels which have effectively removed phytoplankton from the water column (Malkin et al. 2010). The transfer of energy (from pelagic to benthic pathways) associated with accelerated…

    Phil Ross has grown furniture from fungus and thinks his sustainable mushroom-based material can be used to replace a variety of manufactured materials, including plastics and engineered wood. (Katie McKracken/Workshop Residence) Why build a home if you can grow one? San Francisco-based artist Phil Ross has spent the last 20 years developing sustainable materials from mushrooms. Although Ross originally cultivated mushrooms as food, he quickly became fascinated by their potential as an artistic medium. He started growing sculptures and other structural forms out of fungus. And through a…

Hunter-gatherers follow the animals as they graze in different places. Pastoral nomads have animal herds and move them around to where the grazing is best. But the interesting ones are the peripatetic nomads. These are people that move around within cities and other populated areas, often to sell services or trades. Romanis, or gypsies as they are sometimes called, are a group of peripatetic nomads.We humans have complex…

    Biology concepts – motility, microbiology, bacteria, evolution, gliding, twitching, flagella, pilus The Giant Devil Ray, or mobula ray (Mobula mobular) can reach 18 ft. (5.4 m) wide. It’s not so much that they fly or glide, they just breach the waves and look like they are trying to flap wings. They were almost fished to extinction in the 1970’s. Their meat was sold as scallops after they cut it out with a round cookie cutter!How many different ways can humans move about?

  • Extremophile key to nuclear waste disposal

    LaboratoryNews
    19 Sep 2014 | 12:00 am
    A subterranean bacterium could solve the problem of how to dispose of nuclear waste say researchers at the University of Manchester. This is the first time a microbe capable of surviving in the harsh conditions expected in radioactive waste disposal sites has been found. This extremophile was found in an industrial site in the Peak District which suffers from severe contamination with highly alkaline lime kiln wastes. These conditions mimic those expected in cement-based radioactive waste. When groundwaters reach these underground vaults, they react with cement, becoming highly alkaline. This…
  • Splitting water based on nuclear spin

    LaboratoryNews
    19 Sep 2014 | 12:00 am
    Separation of water based on the nuclear spin of individual molecules has been made possible thanks to what scientists are dubbing an electric prism. Water exists in two nuclear spin states depending on the orientation of the spin of the hydrogen atoms. They can be either ortho – symmetric with both spins in the same direction, or para –asymmetric with the opposite spins. In theory, water should not be able to switch between the two, but often do as they collide with each other and surfaces around them. “It is very challenging to separate them and produce water that is not a mixture of…
  • Freshwater springs likely played role in early human evolution

    LaboratoryNews

    The ability to move and seek out new sources of groundwater in dry periods may have been pivotal to survival and evolution of the human species. By combining geological evidence from the Olduvai sedimentary basin in Northern Tanzania with a hydrological model, researchers have shown that while water in rivers and lakes disappeared as the climate changed, freshwater springs fed by groundwater could have remained active for up to 1,000 years without any rainfall. “A major unknown connected with human evolution in this climatically turbulent environment is the availability of resources,…

Although these new CFCs have never been produced on an industrial scale, small amounts have escaped as industrial by-products and are being found in lower concentrations than classic ozone depleting substances (ODS). “The newly detected CFCs have concentrations which are 100-1000 times lower than the major CFCs in the atmosphere,” said Stefan Reimann, part of the EMPA research team who contributed to the…

    A new therapy aimed at treating infants as young as 6-months-old who exhibit signs of autism has shown promising results.  The treatment – pioneered by the University of California Davis MIND Institute – has significantly reduced symptoms so that, by age 3, most who received the therapy showed no signs of autism spectrum disorder (ASD) or developmental delay. Called Infant Start, the behavioural therapy was administered over a 12-week period to seven 7-15-month-old infants showing signs of ASD, such as decreased eye contact and social engagement and a fondness of repetition. “Most of…

    Science News Desk
    19 Sep 2014 | 7:04 am
    Paratuberculosis is a bovine disease affecting up to 19 percent of dairy farms in Austria. Calves become infected via exposure to a bacterium through contaminated faeces or milk and can develop heavy diarrhoea years later. The affected animals must be culled from the herd as quickly as possible. In order to recognize the disease before it manifests, researchers from the University of Veterinary Medicine, Vienna, for the first time employed a rapid test of the lymphatic fluid of the animals.read more

    In the age of the selfie and the selfie-stick, it’s worth quizzing ourselves on how a camera takes a picture? By capturing the light that bounces off an object. Photo credit: Gabriela Barreto Lemos and co-authors/Vienna Center for Quantum Science and Technology But in an experiment, led by Gabriela Barreto Lemos, at the Austrian Academy of Sciences in Vienna, reported in the journal, Nature, the team was able to take a picture of an object, without having a beam of light, or a stream of photons, ever striking—and bouncing off—the object. This quantum camera, if you will, was able to…

    In Isaac Asimov’s “Prelude to Foundation”—a prequel to the “Foundation” series, a science-fiction epic in seven volumes—Dors Venabili says, “Human beings are a single species, spread all over the Galaxy, so they must have originated somewhere.” Hari Seldom replies, “Earth? Is that what they call the supposed world of origin?” The novel is set in the far-future, when humans have colonized vast tracks of our home galaxy and created a complex civilization that presides over a jaw-dropping 25,000,000 planet-provinces. In reality, we haven’t been able to return to our…

    By Anupum Pant At school we were expected to remember things. Every single piece of misplaced information in your brain costed you points  in tests. You couldn’t afford to forget – The very mental pressure which caused panic and made you forget things! Turns out, there is a forgetting protein in our brains called Musashi. It messes with the way nerve cells in the brain communicate with each other – basically makes you forget stuff. Scientists have, genetically modified ringworms to clear Musashi off their brains. As expected, the Musashi free ringworms remembered things…

    By Anupum Pant Neurological conditions can be bizarre. Now I know that there is a condition that can delude patients to such an extent that they start thinking they no longer exist, or are dead. It’s called the Cotard Syndrome or the walking dead disorder. Named after a French doctor Jules Cotard, the Cotard syndrome is a neurological condition in which severe degeneration of neural synapses occurs and messes with the facial recognition and emotion centres of the brain. Their brain creates a totally impaired perception of the self. As a result, patients suffering from it some times…

    Anupum Pant
    17 Sep 2014 | 10:35 am
    By Anupum Pant The internet is full of media saying that pain can be measured in units called “del”. According to them 45 del is the limit of pain a human can endure and yet, they go on to say that child birth is associated with 57 del of pain (apparently it is equivalent to 20 bones getting fractured at a time) and getting kicked in the nuts is 9000 del of pain. I know getting kicked in the nuts, or giving birth to a child is not a joke. It is indeed extreme pain. But if it’s more than what a human can endure, most of us shouldn’t be alive, going by the…

    Female Adder giving birth to live young.Ovoviviparous is the term used for reptiles that give birth to live young, which only represents about 20 percent of the modern scaled reptile population. Ovoviviparous species are similar to viviparous species, in that there is internal fertilization and the young are born live, but differ because the young are nourished by egg yolk as there is no placental connection. Most reptiles give birth to live young, but there are some reptiles that do have placenta like structures capable of transferring nutrients, and are therefore considered viviparous…

  • 6 Organisms That Can Survive The Fallout From A Nuclear Explosion

    Morgans Lists
    29 Aug 2014 | 2:13 pm
    An animal's ability to survive the fallout from a nuclear explosion is usually dependent on its ability to withstand radiation, otherwise know as radioresistance. Radioresistant life forms or ionizing-radiation-resistant organisms (IRRO) are a group of organisms that require large doses of radiation, 1000 gray (Gy), to achieve a 90% reduction in their survival rate. To put it in perspective, a human would need anywhere between 4-10 (Gy) to achieve the same result and a dog could withstand even less, about 3.5 (Gy). Gray, with the symbol of (Gy), is a unit of measurement used to describe the…

Distributed by meteoroids, asteroids, comets, and even through spacecraft via unintended contamination from alien contact. For example, during an Apollo mission to the moon there was a stowaway, the common bacteria Streptococcus mitis, took a walk on the moon with the astronauts and lived to return home and tell it's tale. In 1991, Apollo 12 Commander Pete Conrad commented on the significance of the only known microbial survivor of harsh interplanetary travel:"I always…

    Performance art challenges accepted conventions and traditional forms of visual art such as painting and sculpture. Sometimes performance art focuses on the human body as it's canvas through movement, dance, or actions and activity not usually associated with art. It is normally presented live by the artist and their collaborators and sometimes with hired performers. Recently, performance art is becoming more and more unusual as the bounds of conventionality are stretched further and further to shock audiences and enable new artists to make a name for themselves.

This process, known as metastasis, can cause cancer to spread with deadly effect.

This book clearly states: “Anger injures the liver, joy hurts the heart, sadness weakens the lungs, worry damages the spleen, and fear wounds the kidneys.” There is truth to the wisdom of the ancient Chinese—disease and illness often do stem from emotions. Each emotion releases a specific chemical protein into your body. These are like little messages, and they each set off different physiological reactions—some healing, some harmful.
