by Kristin L. Dunkle, Rachel K. Jewkes, Daniel W. Murdock, Yandisa Sikweyiya, Robert Morrell Background In sub-Saharan Africa the population prevalence of men who have sex with men (MSM) is unknown, as is the population prevalence of male-on-male sexual violence, and whether male-on-male sexual violence may relate to HIV risk. This paper describes lifetime prevalence of consensual male–male sexual behavior and male-on-male sexual violence (victimization and perpetration) in two South African provinces, socio-demographic factors associated with these experiences, and associations with HIV…

Capturing music from the stars
ZME Science14 Jun 2013 | 8:01 amMusica Universalis or Music of the Spheres is an philosophical concept which portrays the proportions in the movement of the celestial bodies – the sun, planets, stars and so on – as a form of music. These observable patterns aren’t quite musical, since they lack harmony, but the idea itself has influenced a great of artists, namely musicians in this case. However, is it possible to take this concept literally? Can stars create music? The short answer would be yes, and a fantastic project initiated by Gerhard Sonnert, a research associate at the Harvard-Smithsonian Center… -

D-Wave's Quantum Computer Courts Controversy
19 Jun 2013 | 10:00 am“I've been doing combative stuff since I was born,” says Geordie Rose, leaning back in a chair in his small, windowless office in Burnaby, Canada, as he describes how he has spent most of his life making things difficult for himself. Until his early 20s, that meant an obsession with wrestling -- the sport that, he claims, provides the least reward for the most work. More recently, says Rose, now 41, “that's been D-Wave in a nutshell: an unbearable amount of pain and very little recognition”. [More] -

Counterpoint: The U.S. Could Totally Kill Edward Snowden With A Drone Strike
19 Jun 2013 | 10:00 amA panoramic view of the Hong Kong skyline taken from a path around Victoria Peak Photo by David Iliff via Wikimedia Commons Here's how In a recent PopularScience.com post, contributing writer Kelsey Atherton suggests that Edward Snowden is at no risk from a U.S. drone strike in Hong Kong because of Chinese air defenses and the risk of collateral damage in the densely populated city. It's true that a strike by a Predator or Reaper drone, which can't penetrate air defenses and cause significant collateral damage with standard weapons, could be ruled out-but the military and the CIA have plenty… -
A Cocktail Scientist Debunks Myths About Ice Cubes
19 Jun 2013 | 9:30 amIce Cubes Nattu The cold, hard facts True or false?: Ice cubes get cloudy because of mineral impurities. True or false?: Larger ice cubes melt more slowly than small ones. True or false?: Shaking a martini "bruises the gin." Many of us use ice every day, and soon we start to think we know all there is to know about it. When to shake, when to stir, the difference between one big cube in a drink versus lots of little ones, and so forth.

This interactive timeline is an attempt to highlight some of the most important events in that history, though it is by no means comprehensive: each event, in turn, has its own string of relevant events, nearly ad infinitum.

A Brief History Of The Demise Of Battle Bots

The wedge-style bot killed robot wars because it was invincible, which in the end made it boring. Yesterday SB Nation published a fascinating full history of BattleBots, which is a great, though giant, read. But the mechanical evil that is…

Dyslexia: Not the only reading disorder

Dyslexia, a reading disorder in which a child confuses letters and struggles with sounding out words, has been the focus of much reading research. But that’s not the case with the lesser known disorder Specific Reading Comprehension Deficits (S-RCD), in which a child reads successfully but does not sufficiently comprehend the meaning of the words, according to lead investigator Laurie Cutting of Vanderbilt University’s Peabody College of… -

No Danger Of Cancer Through Gene Therapy Virus AAV-LPL S447X
19 Jun 2013 | 9:00 amIn the fall of 2012, the European Medicines Agency approved the modified adeno-associated virus AAV-LPL S447X as the first ever gene therapy for clinical use in the Western world. AAV-LPL S447X was developed for the treatment of a rare inherited metabolic disease called lipoprotein lipase deficiency which affects approximately 1-2 out of 1,000,000 people. Though incredibly rare, the disease causes severe, life-threatening inflammations of the pancreas. Afflicted individuals carry a defect in the gene coding for the lipoprotein lipase enzyme which is necessary for breakdown of fatty acids. -
Unusual Supernova SN 2011fe - Move Along, Nothing To See Here
19 Jun 2013 | 8:22 amIn August of 2011, astronomers witnessed the dazzling appearance of the closest and brightest Type Ia supernova since Type Ia's were established as the "standard candles" for measuring the expansion of the universe. The visual of SN 2011fe was caught by the Palomar Transient Factory less than 12 hours after it exploded in the Pinwheel Galaxy in the Big Dipper. Because it was to see through binoculars, 2011fe was soon dubbed the Backyard Supernova. Major astronomical studies from the ground and from space followed close on its heels, recording its luminosity and colors as it rapidly brightened… -
The Elusive H7N9 Virus: Chinese Researchers Predict Future Pandemic
18 Jun 2013 | 5:38 pmSince February 2013, China experienced an outbreak of the novel H7N9 avian flu, causing 131 cases of infection, and a death toll of 39. 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. According to the May 23, 2013 Science paper published by the Joint Influenza Research Centre (State Key Laboratory of Emerging Infectious Diseases, Shantou PR, China), Drs. Y. Guan and Y. Shu reported that H7N9 infects the upper respiratory tract of…

Guiding pledge 2.0 dismisses God and the Queen
19 Jun 2013 | 12:35 amApparently, the Guiding Movement is to upgrade its pledge that all members must make when they join. Currently they vow to: "to love my God, to serve my Queen and my country" That obviously only applies to people of faith and those with a female monarch…and indeed compromises the integrity of those girls without fixed national domicile. So, after consultation the century-old organisation is planning a bit of a rewording, dropping references to both spiritual and earthly autocrats as well as geography it seems. The pledge will now contain the line: "be true to myself and… -
Life on the rocks

But the spinning ball was not alone on its journey – there were countless misshapen chunks of rock and ice and frozen gases in its vicinity, many with eccentric orbits around the central fusion reactor. These comets and other solar debris could skim past or shift in their orbits at the whim of great balls of gas and rock, although always ruled by the laws of the… -
What do you do if you’ve got osteoarthritis of the knee?

Dietary DMAA, dimethylamylamine, death

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…

Citizen Science: Rinse & Repeat
13 Jun 2013 | 6:00 amOne of the funny things about language is that everybody has their own. There is no "English" out there, existing independently of all its speakers. Instead, there are about one billion people out there, all of whom speak their own idiolect. Most likely, no two people share exactly the same vocabulary (I know some words you might not, possibly including idiolect, and you know some words I don't). Reasonable people can disagree about grammar rules, particularly if one is from Florida and the other from Northern Ireland. This is one of the reasons we decided to ask people to create usernames in… -

You can hit at a window or kick at a window but not shatter at a window or break at a… -
Bad Evolutionary Arguments
31 May 2013 | 7:00 amThe introductory psychology course I teach for is very heavy on evolutionary psychology. The danger with evolutionary explanations is that it's pretty easy to come up with bad ones. Here's the best illustration I've seen, from Saturday Morning Breakfast Cereal: How do you tell a good evolutionary argument from a bad one? It's hard to test them with experiments, but that doesn't mean you can't get data. Nice supporting evidence would be finding another species that does the same thing. This hypothesis makes the clear -- and almost certainly false -- prediction that people are likely to adopt… -

Protect your head – the world is complex
13 Jun 2013 | 10:42 amThe British Medical Journal has a fascinating editorial on the behavioural complexities behind the question of whether cycling helmets prevent head injuries.

Maybe putting a bike helmet on a crash test dummy and throwing rocks at its head. Or counting how many cyclists with head injuries were wearing head protection – but it turns out to be far more complicated. The piece by epidemiologist Ben Goldacre and risk scientist David Spiegelhalter examines why the social and… -
When giving reasons leads to worse decisions
11 Jun 2013 | 1:37 amWe’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…

18 Jun 2013 | 10:49 amStudent guest post by Carrie Ellsworth During the summer of 2010 I spent two months in Ghana studying a parasite called schistosomiasis. 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… -
What do flies, fish, mice and worms have to do with biomedical science? [Life Lines]
18 Jun 2013 | 10:15 amImage of common model organisms from European Molecular Biology Laboratory (EMBL). A recent article posted in the BBC News provided a good explanation of why scientists commonly study these organisms as models for human diseases and conditions. Model organisms are chosen because their physiology is similar to other animals, including humans, in addition to other reasons: Visit the BBC News to see why researchers most often use flies, fish, mice and worms to understand the mechanisms of disease and health.

How high can the sea level rise if all the glacial ice melted? [Greg Laden's Blog]
18 Jun 2013 | 9:24 amThere 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… -

Transcription-Factor-Mediated DNA Looping Probed by High-Resolution, Single-Molecule Imaging in Live E. coli Cells
18 Jun 2013 | 2:00 pmby 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
18 Jun 2013 | 2:00 pmby 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… -
NKT Cell-TCR Expression Activates Conventional T Cells in Vivo, but Is Largely Dispensable for Mature NKT Cell Biology
18 Jun 2013 | 2:00 pmby 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… -

Exploring Volatile General Anesthetic Binding to a Closed Membrane-Bound Bacterial Voltage-Gated Sodium Channel via Computation
13 Jun 2013 | 2:00 pmby 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… -
Modelling Co-Infection with Malaria and Lymphatic Filariasis
13 Jun 2013 | 2:00 pmby 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… -

High Trans-ethnic Replicability of GWAS Results Implies Common Causal Variants
13 Jun 2013 | 2:00 pmby 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. Most loci and SNPs… -
Meiosis-Specific Stable Binding of Augmin to Acentrosomal Spindle Poles Promotes Biased Microtubule Assembly in Oocytes
13 Jun 2013 | 2:00 pmby 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…

Efficient Sensing of Infected Cells in Absence of Virus Particles by Blasmacytoid Dendritic Cells Is Blocked by the Viral Ribonuclease Erns
13 Jun 2013 | 2:00 pmby Sylvie Python, Markus Gerber, Rolf Suter, Nicolas Ruggli, Artur Summerfield Plasmacytoid dendritic cells (pDC) have been shown to efficiently sense HCV- or HIV-infected cells, using a virion-free pathway. Here, we demonstrate for classical swine fever virus, a member of the Flaviviridae, that this process is much more efficient in terms of interferon-alpha induction when compared to direct stimulation by virus particles. By employment of virus replicon particles or infectious RNA which can replicate but not form de novo virions, we exclude a transfer of virus from the donor cell to the… -
Host Defense and Recruitment of Foxp3+ T Regulatory Cells to the Lungs in Chronic Mycobacterium tuberculosis Infection Requires Toll-like Receptor 2
13 Jun 2013 | 2:00 pmby Amanda McBride, Jill Konowich, Padmini Salgame Acute resistance to low dose M. tuberculosis (Mtb) infection is not dependent on Toll-like receptor (TLR) 2. However, whether TLR2 contributes to resistance in chronic Mtb infection has remained uncertain. Here we report that, following low dose aerosol infection with Mtb, mice lacking TLR2 (TLR2KO), in comparison with wild type (WT) mice, exhibit enhanced cellular infiltration and inflammation in the lungs, and fail to stably control bacterial burden during chronic infection. IFNγ and IL-17 was expressed at equivalent levels in the two… -

Sub-Inhibitory Concentrations of Human α-defensin Potentiate Neutralizing Antibodies against HIV-1 gp41 Pre-Hairpin Intermediates in the Presence of Serum
13 Jun 2013 | 2:00 pmby Lusine Demirkhanyan, Mariana Marin, Wuyuan Lu, Gregory B. Melikyan Human defensins are at the forefront of the host responses to HIV and other pathogens in mucosal tissues. However, their ability to inactivate HIV in the bloodstream has been questioned due to the antagonistic effect of serum. In this study, we have examined the effect of sub-inhibitory concentrations of human α-defensin HNP-1 on the kinetics of early steps of fusion between HIV-1 and target cells in the presence of serum. Direct measurements of HIV-cell fusion using an enzymatic assay revealed that, in spite of the modest…

Firefox addon warns you about PRISM
15 Jun 2013 | 2:20 amA new Firefox add-on, called “Dark side of the Prism“, has been designed to warn Internet users who have installed it automatically when they visit websites of companies linked to the government surveillance system Prism. All users have to do is install the add-on in Firefox, it will work passively from that moment on. Once you visit a website of a company associated with Prism, it starts to play the song Dark Side of the Moon by Pink Floyd. It also displays a logo at the top right for a second or two before it vanishes. Well spotted Martin Brinkmann. Post from: David Bradley's… -

Doubling up power on the road
6 Jun 2013 | 4:04 amThe team at Innergie sent me an mMini DC10 for review, this their double USB in-car charger. Lets you power two USB devices at once in the car. Perfect for families with smart phones, satnavs and other gadgets, cuts down on the number of charging arguments and is compatible with iOS devices. Gives you dual power without the bulk of one of those bulky multi-adaptor-adaptors. There is little to tell other than to say it does what it says on the box and works well. 10 Watts and a blue LED to let you know it’s plugged into your “cigarette lighter” properly.

Twitter trend detection algorithm
19 Jun 2013 | 6:56 amStuff happens, and people tweet about it. Something major happens, and a lot of people tweet about it. Masters student Stanislav Nikolov and his adviser Devavrat Shah are working on ways to algorithmically detect the latter. People acting in social networks are reasonably predictable. If many of your friends talk about something, it's likely that you will as well. If many of your friends are friends with person X, it is likely that you are friends with them too. Because the underlying system has, in this sense, low complexity, we should expect that the measurements from that system are also… -
Animation shows flow of attendees during a conference
18 Jun 2013 | 9:13 amWhen you go to a conference, there are typically several talks going on at the same time, and you can always tell there's a popular paper coming up when you see people leave a bunch of rooms at once and head straight into one.

Non-statistician analysts are the new norm
17 Jun 2013 | 9:31 amAs data grows cheaper and more easily accessible, the people who analyze it aren't always statisticians. They're likely to not even have had any statistical training. Biostatistics professor Jeff Leek says we need to adapt to this broader audience. What does this mean for statistics as a discipline? Well it is great news in that we have a lot more people to train. It also really drives home the importance of statistical literacy. But it also means we need to adapt our thinking about what it means to teach and perform statistics. We need to focus increasingly on interpretation and critique and… -
The differences between a geek and a nerd
14 Jun 2013 | 8:59 amCurious 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… -
Sniffing out Paul Revere with basic social network analysis

Using metadata from Paul Revere's Ride on the groups that people belonged to, Healy sniffs out Paul Revere as a main target. Bonus points for writing the summary from the point of a view of an 18th century analyst. What a nice picture! The analytical engine has arranged everyone neatly, picking out clusters of individuals and also showing both peripheral individuals and—more intriguingly—people who seem to bridge…

The rhythm of the Arctic summer: Diverse activity patterns of birds during the Arctic breeding season
19 Jun 2013 | 9:21 amOur 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 biologists have now found, in four bird species in Alaska, different daily activity patterns ranging from strictly rhythmic to completely arrhythmic.

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…

Kidney Transplant – Is Kidney Transplant Good For You?
25 Mar 2013 | 4:26 amThe 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
18 Jun 2013 | 9:28 amArs 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
18 Jun 2013 | 9:15 amNew 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…

The Healing Properties of St. John’s Wort
30 May 2013 | 8:36 pmSt. John’s Wort or Hypericum perforatum, is a yellow flowering plant that is a well-known folk remedy for treating emotional disorders. Some believe that it rids the body of evil spirits. It is one of the most used and one of the best-selling herbs in the United States. The healing properties are both in the flowers and the leaves. St. John’s Wort is native to Europe and Southwestern Asia, but it can be found in the United States and Canada. It is grown in Australia as a crop, providing 20% of the world’s supply. This is after it was once considered… -
Kepler Spacecraft Stalled in Search for Exoplanets
28 May 2013 | 8:29 pmIf you visit NASA’s Kepler site, you will see that the most recent posts aren’t concerned with new exoplanetary discoveries, but with the Kepler spacecraft itself. The computer aboard this tiny ship consistently returns itself to safe mode – rather like your home computer rebooting itself and restarting in a Windows safe mode. That Kepler’s computer system reboots itself is not a concern, but a reward to the NASA scientists that designed it. Rather than waste precious fuel running in an error mode, Kepler shuts itself down to try and figure out the problem… -

Kepler Telescope Reveals Stunning Exoplanet Population
23 May 2013 | 7:47 pmBack 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…

Not really 'bath salts' -- paper provides update on 'designer stimulants'
19 Jun 2013 | 12:00 amThe last few years have seen the emergence of a new drug problem in so-called "bath salts" -- actually "designer stimulants," packaged and sold in ways that skirt drug laws. A review and update on these designer drugs is presented in the June Journal of Addiction Medicine, the official journal of the American Society of Addiction Medicine. The journal is published by Lippincott Williams and Wilkins, a part of Wolters Kluwer Health. -

Brain imaging study eliminates differences in visual function as a cause of dyslexia
18 Jun 2013 | 12:00 amA new brain imaging study of dyslexia shows that visual system differences do not cause the disorder, but instead are likely a consequence. "Our results confirm that differences in the visual system of children with dyslexia are the end-product of less reading, when compared with typical readers, and are not the cause of their struggles with reading," said Guinevere Eden, director, Center for the Study of Learning at Georgetown University; past-president, International Dyslexia Association. -

Albert Einstein’s secret to learning anything
17 Jun 2013 | 11:42 amIn 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… -
Russian tycoon wants to transfer the human mind to machines by 2045 and secure immortality
17 Jun 2013 | 8:07 amThis weekend, one of the most curious and utopian conferences took place in New York City, where some of the brightest minds in the field of neuroscience, biotechnology and robotics gathered to discuss the prospect of transferring the human brain and mind out of the biological body and into an artificial vessel. As oddball and SciFi as this might seem, at the conference, which was organized and financially backed-up by a most ambitious Russian multimillionaire, a clear schedule was outlined that seeks to meet this goal by 2045. 2020: humans will be able to remotely robots using our brains,… -
Capturing music from the stars
14 Jun 2013 | 8:01 amMusica Universalis or Music of the Spheres is an philosophical concept which portrays the proportions in the movement of the celestial bodies – the sun, planets, stars and so on – as a form of music. These observable patterns aren’t quite musical, since they lack harmony, but the idea itself has influenced a great of artists, namely musicians in this case. However, is it possible to take this concept literally? Can stars create music? The short answer would be yes, and a fantastic project initiated by Gerhard Sonnert, a research associate at the Harvard-Smithsonian Center… -
Poverty might cause changes to the brain
14 Jun 2013 | 7:16 amIt’s rather clear that social-economic factors have a huge part to play in the development of an individual, but when discussing this we typically refer to education, something that can be more or less manipulated at any time, albeit with various degrees of difficulty. How do social-economic aspects affect the brain, though? Martha Farah, the founding director for Penn’s Center for Neuroscience and Society is currently conducting research in this direction, and so far her preliminary results seem to suggest that the brain’s response to circumstances of social class… -
Stem Cell therapy could help us grow back fingers
14 Jun 2013 | 6:50 amMammals can naturally regenerate the very top of their fingers and toes after amputation; starting from this idea, researchers have demonstrated the mechanism that describes this process, and explain how stem cells from nails could play a pivotal role in future regeneration of entire fingers. A study conducted on mice showed that the chemical signal that triggers stem cells to develop into new nail tissue also attracts nerves that promote bone and nerve regeneration. The study suggests that nail stem cells could be used to develop new regeneration treatments for amputees. Mice are pretty…

How would your life change? For most of my energy entries, I’ve talked about conservation at the individual level. That’s because I know we can make changes in what we do and how we view the world. However, it is always heartening to see large groups take up the challenge. And while a nation should have a plan, unless its citizens are behind it, it will never work. That’s why I’m glad to report on some cities and regions…

Developing cancer drugs
17 Jun 2013 | 11:56 amHarvard 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… -

"Planets Billions of Years Older Than Earth May Exist in the Milky Way" (Featured Post)
18 Jun 2013 | 9:02 amBuilding 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

Deciding Where to Put Your Vegetable Garden
26 Aug 2012 | 7:17 amChoosing 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,… -

the infinitely vast, mandatory miltiverse?
15 Jun 2013 | 11:06 amAt 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… -
how to approach a problem with mind wide shut
12 Jun 2013 | 2:44 pmAlarmed by the growing number of atheists among the current generation of young adults, one organization of Christians decided to sit some down for an interview to learn why they became atheists, drew conclusions, summed them up, and respectfully posted them online. Unlike many other faith groups, they legitimately wanted to understand what atheists thought and why, and what prompted their de-conversions. Problem is that they didn’t want to understand if all those atheists they interviewed had a point when discussing the improbability of an omniscient deity in their lives, ruling the… -
social media, the best way to share with friends, family, and nsa analysists
11 Jun 2013 | 2:21 pmOn the one hand, I am somewhat surprised by recent revelations about exactly how much we’re being watched on the internet by the NSA. However, the big surprise for me is that they couldn’t get data form Twitter. Considering that it’s building an immense data center in Utah, and works with tech companies on a regular basis, is it really that astonishing that the agency is browsing through our communications metadata on a regular basis? We all suspected this was the case, so if anything the current furor is almost a required reaction of anger and hurt to have what we always… -
why mars is not the next apollo
10 Jun 2013 | 5:15 amAccording to Wired’s laundry list of technical and political issues with getting humans to Mars by the year 2030 or so, exploring another planet many millions of miles away won’t be Apollo 2.0 in many ways. It will be an order of magnitude more expensive per launch, require 30 months for a round trip, and needs to be financed, overseen, and executed by an international group that will include space agencies and ambitious aerospace companies with plans and launch vehicles of their own. And yet, the designs being drawn up sound remarkably like Apollo on steroids. We’re… -
the impotent cry against reason and logic
8 Jun 2013 | 12:02 pmEver since the New Atheists arrived on the scene, there’s be a loud, wailing siren from religious and humanities pundits decrying the idea that we could use science to explain the universe that we occupy. Generally their argument for why we can’t use reason and experiments to clear up a lot of mysteries and what makes us tick boils down to "how dare you say you can explain all this complexity and wonder in math and mechanistic descriptions?" And that’s really as far as it goes because their objection to using science to explain their pet topics in the language of…

More data storage? Here's how to fit 1,000 terabytes on a DVD
19 Jun 2013 | 2:00 amWe 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… -

18 Jun 2013 | 1:39 pmThe official reinstatement of confessed doper Matt White as sports director of Australian World Tour pro-cycling team Orica-GreenEdge passed with surprisingly little media or public scrutiny last week. But while many fans may feel justified in switching off the drugs in sport saga, this latest development in Australian cycling deserves much closer focus than it is presently attracting. White’s return to Orica-GreenEdge comes eight months after his October 2012 admission to doping as a professional cyclist with Lance Armstrong’s US Postal Service team.

Guiding pledge 2.0 dismisses God and the Queen
19 Jun 2013 | 12:35 amApparently, the Guiding Movement is to upgrade its pledge that all members must make when they join. Currently they vow to: "to love my God, to serve my Queen and my country" That obviously only applies to people of faith and those with a female monarch…and indeed compromises the integrity of those girls without fixed national domicile. So, after consultation the century-old organisation is planning a bit of a rewording, dropping references to both spiritual and earthly autocrats as well as geography it seems. The pledge will now contain the line: "be true to myself and… -
Life on the rocks

But the spinning ball was not alone on its journey – there were countless misshapen chunks of rock and ice and frozen gases in its vicinity, many with eccentric orbits around the central fusion reactor. These comets and other solar debris could skim past or shift in their orbits at the whim of great balls of gas and rock, although always ruled by the laws of the… -
What do you do if you’ve got osteoarthritis of the knee?

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).

Dietary DMAA, dimethylamylamine, death
7 Jun 2013 | 2:58 amDMAA 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
14 Jun 2013 | 3:05 amTim 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… -
Restoring the Earth's "Kidneys"
12 Jun 2013 | 8:00 amAnthony 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… -

Recycling a House

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.

The Roots Of Our Animal Family Tree
19 Jun 2013 | 5:00 amBiology concepts – porifera, last common ancestor, placozoa, cladogram, lower metazoan, bilaterians Bonobo apes (Pan paniscus) are very closely related to chimpanzees. They have longer legs than common chimpanzees (Pan troglodytes) and are also distinguished by having pink lips. I think this makes them look significantly more human-like. Also like humans, the families seem to be run by the mothers.Humans are descended from primates; we share 99% of our DNA with chimpanzees and Bonobos (pygmy chimps). But what do we find as we go farther back along the line of mammals, and then from animals… -

Universe evolved ability to make black holes
19 Jun 2013 | 1:00 amThe maths underpinning Darwin’s theory of natural selection might explain how the universe may be designed to make black holes. Researchers from Oxford University propose that if new universes are born inside black holes, a ‘multiverse’ of main possible universes could be shaped by a process similar to evolution so that successive generations of universes become better at making black holes. “This idea of cosmological natural selection is controversial, and physicists have pointed out all sorts of problems with it. But we were interested in seeing if its basic evolutionary logic… -
Coral reefs could be saved by geoengineering
17 Jun 2013 | 1:00 amAt-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… -

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.

Weighing the Benefits and Risks of Breast Reconstruction Surgery After Mastectomy
18 Jun 2013 | 10:13 pmBy Fonthip Maspithak Breast cancer is no longer the death sentence it was decades ago. Improved medical interventions result in more survivors – even with the most aggressive forms of cancer. While women are concerned for their health, they may also be concerned about restoring the appearance of their breasts, leading them to consider breast reconstruction – a procedure performed after a mastectomy to restore the breast to its original size and shape. While it has risks, new methods provide women with greater and safer options to regain their previous shape. Breast… -
Advancements of Scientific Research
18 Jun 2013 | 9:07 pmBy Jessica Reynolds Over the many decades involving research, knowledge, and the progress of science, we can see and understand the differences in how scientists have changed their processes. Studying electrons in the 1900’s was vastly different from the way we study electrons today; not only with the modern technology we have available, but with regulations that have been implemented. Science and technology are constantly growing and changing; this will never stop. We have many people, ideas, and events to thank for the way our knowledge about how everyday things or incurable diseases… -

How microwave ovens cook food and why is it that they finish the job in as little as fifteen minutes?
1 Jun 2013 | 6:28 amMicrowave 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. But microwave ovens produce heat directly inside the food, heating it more evenly and more quickly than gas stove. Let's see how this works. Inside the microwave oven, a device called magnetron generates the microwaves… -
Why the colours of leaves on the trees turn yellow, orange, red and brown in the autumn?
11 May 2013 | 6:25 amThe 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. -

When a terrorist attack seems likely, authorities declare red alert to step up security. why is such alert called red?
27 Apr 2013 | 6:19 amThe 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.
