Your Facebook Photo Says More Than You Think, Research Says


A photo is worth a thousand words, as the saying goes, but your Facebook photo might be worth more. It is, after all, available to the entire world. Let's face it; we're all vain to varying degrees, and have some sort of self-image that we're constantly trying to project online. A newly released study aims to determine just what it means to project our avatar through the lens of social networking sites.

Researchers from Sonoma State University recently found that images can pretty reliably convey some, though not all, personality traits. In the study, 12 random people looked at photos of 123 undergraduate students in different poses -- both
"neutral" and "spontaneous." (The "neutral" poses were dictated by researchers, while the "spontaneous" poses were self-directed.) The subjects were then asked to rank the photos according to 10 traits: extroversion, agreeableness, conscientiousness, emotional stability, openness, likability, self-esteem, loneliness, religiosity, and political orientation. In order to judge the accuracy of the subjects' appraisals, scientists compared them to the self-evaluations submitted by the photographed students.

Ultrasound Could Protect Pacemakers From Hackers

You never want your wireless device open to attacks, but if that device is implanted inside your body, security becomes even more important. With pacemakers and other medical devices being controlled and monitored from afar, scientists say it's time to step up protection. Those concerns in mind, a group of researchers from the Swiss Federal Institute of Technology and the French National Institute for Research in Computer Science and Control have developed a new safety net.

According to Technology Review
, the system uses ultrasound waves to measure the distance between a medical device and the wireless reader trying to communicate with it. This could prevent potential hackers from wirelessly gaining access to private information stored on the device, draining its battery, or causing it to malfunction. With the ultrasound system, access to the device would be restricted to the physical proximity of the communicator. In the plan proposed by senior researcher Claude Castelluccia and his team, you'd need to go through a series of authentication steps and be within 10 meters of the device in order to gain access.

Avoid The Doctor: Cough Into Your Phone For a Diagnosis

What does that cough say about you? Well, a lot. After all, each one is unique (wet or dry, productive or non-productive). Instead of waiting hours at a doctor's office to find out what this common symptom means, a group of researchers want to use the cell phone to get a quicker diagnosis.

According to Discovery News, a new mobile technology could allow people to forgo a visit to the doctor's office by simply coughing into a cell phone. The new technology, which is being developed by STAR Analytical Services, would allow doctors to listen, measure, and analyze a patient's cough. Just by doing that, a doctor might be able to diagnose any disease from the common cold to the flu. But these scientists want to do more than just scratch the surface of the cough. They're compiling sound data on thousands of different types of coughs and analyzing the distinct sounds which occur at the end of each.

Silk-Silicon Implants Could Connect to Your Brain, Enable LED Tattoos

Biology and technology are increasingly crossing paths these days, so it comes as no surprise that researchers have found a way to literally fuse the two, creating implantable technology for the 21st century.

Researchers have developed a new type of super-thin silicon transistor, which can be embedded on a dissolvable silk-based film (pictured). Brian Litt, associate professor of neurology and bioengineering at the University of Pennsylvania, told Technology Review, "Current medical devices are very limited by the fact that the active electronics have to be 'canned,' or isolated from the body, and are on rigid silicon." These new silicon-silk implants are much easier to place within a body: the silk sheet "melts away," and the transistors are small enough that they don't irritate tissues.

The Science of Mona Lisa's Smile


The subtle complexity of Mona Lisa's sly smirk has captivated generations of casual art enthusiasts, academics, and even scientists. In reality, it is a fine sliver of paint, but in the realm of art, it acts as a monument to the indefinable. But it's time to end the infernal debate: is it a smile or not?

According to a study conducted at the Institute of Neuroscience in Alicante, Spain, the answer is both. Arggggg!

Creepy Japanese Robot Simulates Swine Flu

Most people do anything they can to prevent viruses from infecting their high-tech toys. One group of Japanese scientists, though, have created a robot that actually embraces an especially virulent (and topical) strain: Swine Flu.

The robot , unveiled at the recent Security and Safety Trade Expo (RISCON) in Tokyo as part of a series of flu-prevention devices, is designed to exhibit symptoms of sweating, moaning, and convulsing that are typical of patients infected with the H1N1 virus. If not properly treated, the symptoms deteriorate, and, dramatically, the cyborg stops breathing. The humanoid, according to scientists, aims to assist doctors and medical professionals in their treatment of and education about a virus that, as of October 11, had already led to 4,735 deaths worldwide, as well as around 400,000 confirmed cases, according to the World Health Organization.

More People Updating Their Status Than Ever, Study Finds


The human obsession with "status" is almost as old as human history itself. Though the word has a historically hierarchical connotation, contemporary usage of "status" often has a different, more Twitter-ized meaning. Yet the fascination remains strong and, in a hyper-connected world, is rapidly intensifying.

According to a study conducted as part of the Pew Internet and American Life Project, approximately one in every five Internet users either maintains their status via some social networking medium like Twitter or Facebook, or uses similar sites to keep track of others' statuses. A full 19-percent of those surveyed reported using status-updating Web sites, a marked increase from the 11-percent that similar surveys found last April and December.

Clown on a Unicycle Goes Unnoticed by Cell Phone Users

Clown on a Unicycle Goes Unnoticed by Cell Phone Users
It's conventional wisdom at this point that cell phones are distracting, and that even simple activities like walking can become dangerous endeavors when mixed with texting. We've read, and reported on, study after study concerning cell phone users' lack of awareness, but the particulars of one such study, reported by LiveScience, stands out.

One part of the study, headed by Ira Hyman, Jr. of Western Washington University, involved interviewing 150 students who had just walked across the university's campus. He tried to ascertain whether or not the students had seen anything strange on their stroll. Hyman (Stop giggling... what are you, six?) was hoping the interviewees spotted one of his students who was dressed in a clown suit and riding a unicycle around a prominent sculpture on campus. When asked directly if they had seen such a clown, those who were speaking on the phone or text messaging were far less likely to have noticed the odd scene than were other participants.

The Internet Changes Your Brain, Study Shows

The Internet has firmly burrowed its way into our psyches. We think in 140-character bursts. We Google our memory when we can't, for the life of us, remember the name of that guy from 'Ghost.' We meet new people and imagine a reconfiguration of our Facebook friends list. The Internet has fundamentally changed the way we think, and a newly released study may provide hard, scientific proof of what we've always known.

In a recent UCLA study, adults with little Internet wherewithal showed noticeable changes in brain activity after just one week of online exposure. In fact, researchers suggest that the Internet may even help stimulate and enhance cognition in older adults, a finding that could have significant implications for Alzheimer's and dementia research. The study looked at a group of older adults, aged 55 to 78, half of whom used the Internet on a daily basis and half of whom hardly at all. After researchers used an MRI to examine brain activity while subjects performed online searches, the volunteers were sent home. While there, they spent an hour a day performing Web searches, for a total of seven days. Among the novices, researchers found increased activity in the neural regions controlling language, memory, and vision. Perhaps more interestingly, they discovered that after only one week, those with little prior experience displayed brain activity very similar to that of the more savvy users.

Shakespeare Had Collaborators, Says Computer Program

Thank goodness our e-mail addresses have changed since the days of Shakespeare 101, or we'd be getting big, fat "I told you so's" from our college professors. For as many years as he's been studied, scholars have raged about whether or not Shakespeare had collaborators (or snatched some language from playwrights of his day). However, Sir Brian Vickers at the University of London says he can now prove that Shakespeare got a hand, by using modern-day plagiarism technology.

Vickers took 'Pl@giarism,' a program meant to detect whether or not students have been cheating, and took phrases from 'Edward III,' a play attributed to Shakespeare, and matched them against other dramatic pieces. According to Vickers, 60-percent of the play's phrases are reminiscent of Shakespearean contemporary Thomas Kyd, while only 40-percent suit the Bard himself, leading the professor to conclude that 'Eddy Three' is mostly a work of Kyd's.

You Can Think Your Way to High Definition, Finds Study

Think Your Way to HDTV
This probably isn't too shocking, but a recent study has shown that if you want a better picture from your TV all you have to do is think it's better.

According to a Dutch study published in the journal Computers in Entertainment, the mere suggestion that the quality of an image on television was better was enough to make participants perceive it as such. The researchers showed the same video clip to two different groups of 30 people. The first group was told they would be watching a standard definition DVD quality clip, while the second was told that they would be watching a high definition video. The illusion was backed up with some environmental trickery -- an extra thick cable ran into the TV and the room was filled with posters touting the wonders of high-definition.

Bra Gas Mask Wins Ig Nobel Prize


The Nobel Prizes are always preceded by the Ig Nobel Prizes, which honor research that "makes people laugh and think." This year's Ig Nobel winners have turned tequila into diamonds, studied full versus empty beer-bottle-to-head injuries (turns out they both hurt), and even designed a bra that, during your average chemical warfare blitz, doubles as a pair of gas masks for you and a friend. Dr. Elena Bodnar, winner of the Public Health prize for her bustier-cum-breathing apparatus, demonstrated the effectiveness of her invention on two real Nobel laureates, who presented her award.

Nobel laureates wearing bras on their faces? Why didn't we get invited to this frat party? Bodnar shares her new (ig-)nobility with such dignified past winners as Kees Moeliker, who discovered the propensity for gay necrophilia in ducks, and Dr. Francis Fesmire, whose cure for hiccups involves the manipulation of your interior posterior.

Can Fear-Analyzing Brain Scans Make Scary Movies Scarier?

With Halloween just around the corner, your local multiplex will soon be flooded with horror flicks. And this year, they might be scarier than ever. That's due to the attention one filmmaker has gotten over his novel approach to the genre, using science to discover just why and when people are frightened at the movies.

According to CNN, British producer Peter Katz enlisted Mindsign Neuromarketing to perform a brain scan on a subject as she watched two scenes from the upcoming film 'Pop Skull,' co-written and directed by Alabama duo Adam Wingard and Lane Hughes. During the test, researchers looked for activity in the amygdala, which is the part of the brain linked to fear.

Soldiers' iPods Give Glimpse Into Psyche


With music becoming increasingly accessible, it's now possible to accompany every moment of life with a personalized soundtrack. Not only have iPods and MP3 players pervaded everyday existence, but they've also, not surprisingly, become just as crucial to those most extreme, intense moments -- moments most of us never experience, but which, for soldiers in combat, are the norm.

Such is the backdrop of a recent study by City College of New York music theorist Jonathan Pieslak. For the past few years, Pieslak has interviewed American soldiers about the genres of music that populate their battlefield playlists and the reasons behind their choices. Originally drawn to the subject after reading that, during Desert Storm, 40-percent of the metal band Slayer's fan mail came from soldiers stationed abroad, Pieslak found that soldiers' playlists featured largely aggressive music, like Eminem, Metallica, and Slayer.
