Bruno Zamborlin, a PhD candidate at IRCAM/Centre Pompidou and Goldsmiths, University of London, and Norbert Schnell, a Centre Pompidou researcher, created this astounding demo of using a contact microphone to turn any hard surface into a touch interface. The microphone detects the vibrations from your touches and figures out what kind of touch you're engaged in and what you're touching with, and translates that into music. Don't miss the balloon demo at the end.
Through gesture recognition techniques we detect different kind of fingers-touch and associate them with different sounds.
In the video we used two different audio synthesis techniques:
1- physics modelling, which consists in generating the sound by simulating physical laws;
2- concatenative synthesis (audio mosaicing), in which the sound of the contact microphone is associated with its closest frame present in a sound database.
The system can recognise both fingers-touches and objects that emit a sound, such as the coin shown in the video.
President Obama just signed the National Defense Authorization Act into law despite startling provisions that will allow the military to indefinitely detain American citizens. It's a travesty, defying basic principles of justice and due process in perhaps the most extreme respect our nation has ever seen.
Thankfully, several lawmakers are keeping up the fight. Senator Dianne Feinstein has introduced legislation to undo these provisions of the NDAA, in the form of the Due Process Guarantee Act. We need to urge other Senators to support it.
The Due Process Guarantee Act of 2011 amends the Non-Detention Act of 1971 by providing that a Congressional authorization for the use of military force does not authorize the indefinite detention—without charge or trial—of U.S. citizens who are apprehended domestically.
If there's enough of a public outcry, we have a real chance of making this happen: More than 40 senators voted against the indefinite detention provisions of the NDAA -- and that was before the media and general public caught on to what was happening. Please urge your Senators to remedy this terrible wrong.
Is anyone else surprised that Senator Dianne Feinstein is fighting this? I had her pegged as the most anti-civil-liberties democrat ever born. She must be up to something tricky.

It's hard to explain the experience of expertise. That's why one of the first things they teach you in journalism school is to avoid questions like, "What's it like to be a mathematician?" It's hard for your interview subject to know how to respond and you seldom get a useful answer.
But not never.
On Quora, someone* asks, "What is it like to have an understanding of very advanced mathematics?" And the responses are surprisingly interesting. Especially the first, wherein an anonymous mathematician lays out a detailed account of how advanced mathematics have altered his/her view of the world and of being a mathematician.
• You are often confident that something is true long before you have an airtight proof for it (this happens especially often in geometry). The main reason is that you have a large catalogue of connections between concepts, and you can quickly intuit that if X were to be false, that would create tensions with other things you know to be true, so you are inclined to believe X is probably true to maintain the harmony of the conceptual space. It's not so much that you can imagine the situation perfectly, but you can quickly imagine many other things that are logically connected to it.
• You are comfortable with feeling like you have no deep understanding of the problem you are studying. Indeed, when you do have a deep understanding, you have solved the problem and it is time to do something else. This makes the total time you spend in life reveling in your mastery of something quite brief. One of the main skills of research scientists of any type is knowing how to work comfortably and productively in a state of confusion.
*I couldn't tell who had asked the question. Maybe I'm just not familiar enough with Quora. If you can see a name for the thread's original author, let me know.

There are facts that just aren't apparent from our everyday perspective. Sometimes, in order to really get a scientific concept at the gut level, you have to seek out a different way to view the world. Do that, and you'll find yourself emotionally gobsmacked by well-known concepts you'd long ago accepted intellectually.
For instance, watching this video montage of 9 weeks worth of infrared images from NASA’s GOES-East satellite, the lizard-brain part of me was struck with a sudden realization, "Oh my god. Air really is a fluid, isn't it?"
Thanks to Patrick di Justo for making this and blowing my mind just a little.

Are you there Judy Blume? It's me, Smithsonian:
Do you plan which important life issue you will deal with in a book?
I always have some idea of the story I’m about to tell. I knew Davey’s father would die suddenly and violently in Tiger Eyes. I knew Rachel Robinson’s brother Charles would disrupt the family in Here’s to You, Rachel Robinson. With Are You There God? It’s Me, Margaret, I thought I was writing about organized religion, yet the book has become famous for dealing with puberty. Hardly anyone ever mentions religion or Margaret’s very personal relationship with God. There’s so much I don’t know when I start writing a book. That’s the best part of writing for me—the surprises along the way.
Which character from your books do you identify with the most?
Sally from Starring Sally J. Freedman as Herself. It’s my most autobiographical book. But I identify with all of my characters. A writer has to do so if she wants her readers to identify with them as well.
Four of your books are among the American Library Association’s Top 100 Banned/Challenged Books: 2000-2009. How do authors feel when they are added to this list?
I suspect many authors today are proud because those who challenge their books don’t do so unless they aren’t already popular. But when my books were first attacked in the early 1980s, there was no list and I felt no pride—only anger, sadness and a sense of isolation.
Qamar Hashim, who is 8, takes pictures at al-Mutanabi street in Baghdad. Hashim tours famous streets to picture Baghdadis with his single camera. He is the youngest Iraqi photographer to win several local awards, according to the Iraqi Society Photographic (ISP). Photos above and below taken December 16, 2011.
Are there any photos you wish to take but haven’t been able to yet?
The dangerous pictures like fire, blasts, other incidents but I have been sent off the site. They say I am a child. Also I wish to get a picture of the triangle of migrant birds.
What does the future of Iraq look like?
I see a flourishing future for Iraq especially when my family owns a house. I love Iraq, my home, and it is more precious than anything else.
Following, an assortment of photographs taken by young Mr. Hashim with his camera: A man selling books at al-Mutanabi street in Baghdad, a hawk in a nearby amusement park, a girl standing near a policeman providing security in the city of Kut, women carrying trays of pastries in Sadr City, and kids peeking out from the doorway of their makeshift house in the city of Kut.
In my latest Guardian column, "The internet is the best place for dissent to start," I look at Ethan Zuckerman's recent talk on the Internet and human rights, and the way that cute cats create the positive externality of a place for dissent to begin and flourish, and look at the problems this causes:
Zuckerman's argument is this: while YouTube, Twitter, Facebook (and other popular social services) aren't good at protecting dissidents, they are nevertheless the best place for this sort of activity to start, for several reasons.
First, because when YouTube is taken off your nation's internet, everyone notices, not just dissidents. So if a state shuts down a site dedicated to exposing official brutality, only the people who care about that sort of thing already are likely to notice.
But when YouTube goes dark, all the people who want to look at cute cats discover that their favourite site is gone, and they start to ask their neighbours why, and they come to learn that there exists video evidence of official brutality so heinous and awful that the government has shut out all of YouTube in case the people see it.
The New York Times has a fascinating story about the current state of the science on weight loss, including the results of one recent (albeit small) study that suggests that the human body responds to weight loss by actively trying to regain weight—a finding that could help explain why it's so difficult to maintain significant weight loss, even when you are able to shed pounds.

Here's a fascinating study that shines a bright spotlight of nuance on some of those maybe-too-simplistic assumptions we make about evolution, physical characteristics, and reproductive fitness.
If you've paid any attention to reporting on the science of what humans find attractive and why, you won't be surprised to learn that studies consistently show that deeper voices are associated with stereotypically manly-man characteristics such as hairier bodies and taller height, that men with these voices and characteristics are judged as being more attractive, and that deep-voiced dudes seem to get more action from more ladies.
Based on all of that, you might be tempted to speculate that a deeper voice is an outward sign of how fertile and virile a dude is and that ladies have evolved to be attracted to that show of baby-making prowess. And that makes sense ...
Except that men with deep voices also seem to have lower-quality sperm. At the Anthropology in Practice blog, Krystal D'Costa explains:
These assessments aren’t entirely made up. There is evidence that secondary sexual traits can predict health and fertility of a partner. Brilliant colors and showy displays have long been natural indicators of potential sexual fitness. For example, deer with bigger, more complex antlers also have larger testes and more motile sperm. Lower frequency sounds have been linked to larger body size across all primate species
However, semen analysis reveals that men with deeper voices have lower scores on seven motility parameters (7)—even when the lifestyle and environmental factors are accounted for. While men with deeper voices may have more sexual partners, they seem less prepared to pass on their genes. Researchers believe the lower sperm quality reflects a trade-off that comes with having to compete for mates:
“Animals have finite resources to partition amongst reproductive activities, and the theoretical models of sperm expenditure assume a basic trade-off between male investment in attracting mates and in gaining fertilizations. Recent studies of non-human animals are providing empirical evidence for this basic life-history trade-off. A number of studies have also reported short-term declines in semen quality associated with social dominance."

The Australian blacktip shark lives in tropical waters. The common blacktip shark prefers its water subtropical and temperate. Because of the difference in habitat, these two animals have become separate subspecies with distinct physical differences.
However, there are some places where their habitats overlap. And here, along the eastern coast of Australia, there is interspecies nookie. And hybrid baby sharks.
Now, none of that is particularly shocking. Hybrid zones, where the habitats of two genetically compatible species overlap, aren't ridiculously common, but scientists have documented quite a few. What makes this finding interesting is that the two species and their hybrid have been genetically documented. Hybrid zones can be fuzzy places. What happens there calls into question how sure we can be that that what we call species really are all that different from one another.
What makes this study interesting is that researchers actually performed genetic testing on sharks caught in the hybrid zone. They found distinct genetic differences between the blacktip and Australian blacktip sharks, especially in their mitochondrial DNA. And the hybrids were identified based on genetics as well. That's something that's a lot more rare in the study of wild hybrids. The information gathered here could end up having a lot to teach us about how evolution happens and what speciation really means.
Mineways is a tool that converts your Minecraft creations into 3D files that can be sent to the 3D printing bureau Shapeways, who will print them out in color plastic and send them to you. The tool itself is free/open and there's C/C++ source for you to download.
There are already over 1900 Minecraft tagged items on show, for sale or download in the Shapeways gallery and we are expecting to see many, many more as the game engine, makes 3D modelling fun and accessible to thousands of people. Minecraft and Mineways may end up being a great stepping stone to 3DTin which has a comparable base architecture or Tinkercad which may also be intuitive to those who enter 3D modelling via Minecraft.

Lena Paahlsson, who lives on a farm near Mora, Sweden, says that she found her wedding ring, lost for 16 years, on a carrot in her garden. From the BBC News:
"The carrot was sprouting in the middle of the ring. It is quite incredible," her husband Ola said to the newspaper.
The couple believe the ring fell into a sink back in 1995 and was lost in vegetable peelings that were turned into compost or fed to their sheep.
