Build SuperComputer Using Rasberry Pi
Inspired by the low-cost computing power of the Raspberry Pi, a team at the University of Southampton has used the ARM-based Linux computer-on-a-board as a building block for a low-cost supercomputer. And they’ve published a step-by-step guide.
Led by Professor Simon Cox, the team used 64 Raspberry Pi computers, each equipped with a 16-gigabyte SD card to construct a functioning computing cluster for under £2,500 (a bit over $4,000)—not including the Ethernet swtiches used to connect the nodes.

BlackHole 2.0 The New Exploit Kit
The developer of the toolkit, who goes by the handle "Paunch," recently announced the availability of Blackhole 2.0, which removes much of its trove of known and patched exploits, and replaces them with a whole new crop—along with features that will make it harder for antivirus companies and site owners to detect trouble.
BlackHole is a web-based software package which includes a collection of tools to take advantage of security holes in web browsers to download viruses, botnet trojans, and other forms of nastiness to the computers of unsuspecting victims. The exploit kit is offered both as a "licensed" software product for the intrepid malware server operator and as malware-as-a-service by the author off his own server.
The announcement for the new version was initially posted on the underground hacker marketplace site Exploit.ln, promises a number of new features to make it harder for antivirus software to detect and defend against exploit attacks. One of those is a random URL generation system that creates single-use web addresses for attacks that last only as long as a specific attack on a target computer. Random URLs are intended to prevent antivirus companies or security professionals from using the link to download the exploit for analysis.

Opus Audio Codec For All Application
While most audio codecs aim to solve specific problems—relatively high bit-rate music reproduction such as AAC and MP3, low latency voice reproduction such as Speex and the AMR family—Opus provides a "one size fits all" option which, according to its developers, provides best-in-class quality in almost all applications.
The codec was primarily developed by Mozilla and Xiph.org, with contributions from Skype/Microsoft and Broadcom. Opus weds Xiph.org's low-latency high bitrate music-oriented CELT algorithm to Skype's low bitrate speech-oriented SILK. The codec switches between algorithms depending on the bandwidth available, while boasting real-time latencies across the full bitrate/quality spectrum.

Spinal Stem Cell Injections Reverse Paralysis
New Scientist reports that a small trial involving three partially paralyzed patients saw injections of 20 million neural stem cells administered directly into their spinal cords. The stem cells were harvested from donated fetal brain tissue, and the patients received immunosuppressive drugs to minimize the risks of rejection.
Before treatment, all of the patients could feel nothing below their nipples. Six months on, two of them can now feel touch and heat as far down as their belly button.

Climate Change Will Drive Up Food Prices
Climate change's impact on future food prices is being underestimated, Oxfam warned in a report on Wednesday.
The development charity predicts that massive price spikes will be a devastating blow to the world's poorest people who today spend up to 75% of their income on food.
Its report, "Extreme Weather", "Extreme Price", suggests extreme weather events such as droughts and floods – made more likely by global warming – could drive up future food prices. Previous research has tended to consider gradual impacts of rising global temperatures, such as changing rainfall patterns.
The research claimed that:
• Even under a conservative scenario another US drought in 2030 could raise the price of maize by as much as 140% over and above the average price of food in 2030, which is already likely to be double today's prices.
• Drought and flooding in southern Africa could increase the consumer price of maize and other coarse grains by as much as 120%. Price spikes of this magnitude today would mean the cost of a 25kg bag of corn meal – a staple which feeds poor families across Africa for about two weeks – would rocket from around $18 to $40.
• A nationwide drought in India and extensive flooding across south-east Asia could see the world market price of rice increase by 22%. This could lead to domestic spikes of up to 43% on top of longer term price rises in rice importing countries of such as Nigeria, Africa's most populous country.
• Climate shocks in sub-Saharan Africa are likely to have an increasingly dramatic impact in 2030 as 95% of grains such as maize, millet and sorghum that are consumed in sub-Saharan Africa are expected to come from the region itself.

Spotted Within 3 Hours Because Trading Popular Files on Bittorrent
Users who participate in BitTorrent swarms for popular files are likely to have their IP addresses logged by monitoring companies within three hours. That's the conclusion of a paper being presented this week at the SecureComm conference in Italy by Tom Chothia and colleagues at the University of Birmingham.
Users who think they can evade detection just by using common blocklists are probably fooling themselves. "Publicly available blocklists, used by privacy-conscious BitTorrent users to prevent contact with monitors, contain large incidences of false positives and false negatives," the Birmingham team concludes.

Latest Java Has Bug So Dangerous
Researchers said they've uncovered a flaw in the Java 7 update released by Oracle on Thursday that allows attackers to take complete control of end-user computers.

Deadly DIY Weapons
1. The Bleach Bomb
What's in bleach? Sodium hypochlorite. What's in drain cleaner? Hydrochloric acid. When you mix bleach and an acid-containing drain cleaner, a spontaneous chemical reaction occurs: NaClO + 2 HCl ? Cl2 + H2O + NaCl
The reaction produces poisonous chlorine gas and likely leaves unreacted hydrochloric acid as well. Chlorine gas, even small amounts of it, is bad stuff. As WWI graphically demonstrated, it attacks the membranes in your eyes, throat, and nose, and prolonged exposure can cause death by asphyxiation.
2. Thermite
Not many chemical processes are as gloriously, vigorously, and robustly exothermic as the thermite reaction. Take powdered aluminum (say from the inside of an Etch-a-Sketch) and rusted iron (say from a well-weathered steel wool pad) in just the right proportions and ignite with a sparkler. The reaction that ensues is hot enough to burn through dirt.
3. Styrofoam Napalm
Vietnam War-era napalm was made by mixing of benzene, gasoline, and polystyrene. The stuff was a hellish mixture that clung to surfaces while it burned, and it was practically inextinguishable. It's possible to come up with something pretty darn close to the vintage napalm by simply dunking Styrofoam in a bucket of gasoline, mixing it around for a while and reserving the leftover goo.
4. Maglite Laser
Myriad YouTube videos show how to make a retina-melting, flesh-burning portable laser from a discarded DVD burner and Maglite flashlight. If you remove the laser diode from the burner, then swap it out for the bulb of the Maglite, you essentially turn the flashlight into a handheld, intensely concentrated laser.

Put Taser on AR Drone
To do this, all stickers and extra material was removed from the “indoor” hull of the AR Drone. Use the indoor version because it has this night light frame that extends out past the blades to protect them. This was perfect for allowing it to bump into people.
Then made two tracks with aluminum tape around the entire hull. These were connected with wire directly to the capacitor in a disposable camera. Another weight reduction was to remove all extraneous pieces of the camera. Not only did this make it lighter, but it allowed the entire circuit to be hidden inside the hull. Only a little bit of carving was necessary to make enough space.

Remove Broken Glass With Potato
Start by grabbing a flashlight and turning off the lights in your kitchen. Shine the flashlight in the bottom of the dishwasher. Any pieces of glass will catch the light so you can see where they are. Then take 1/2 of a raw potato, and while wearing thick gloves, run the potato over the glass shards. The glass will become embedded in the potato and be easy to remove. It's also great if you've got glass shards stuck in the garbage disposal, or anywhere else your vacuum doesn't really do the trick.

Hantavirus Pulmonary Syndrome
The hantavirus pulmonary syndrome—formerly Korean hemorrahgic fever—is a rare but often fatal disease. The symptoms seem like influenza mixed with gastrointestinal problems: "fever, chills, sweaty palms, diarrhea, malaise, headaches, nausea, abdominal and back pain, respiratory problems such as the ones." These start "three to seven days and arise about two to three weeks after exposure." After that, a phase that includes tachycardia (abnormally rapid heart rate) and tachypnea (abnormally rapid breathing). Then patients "will develop difficulty breathing, coughing and shortness of breath." At this point, the patient could enter into the "cardiopulmonary phase, where cardiovascular shock can occur, and hospitalization of the patient is required."

People Can Actually Have Their Conscious Behavior Modified During Sleep
At the same time when unpleasant odor were being administered, the researchers matched each smell with a very specific tone. They performed the experiment repeatedly and long enough to provoke a Pavlovian response in the volunteers such that, while they were still sleeping, they could either elicit the shallow or deep breath response by simply playing the sound associated with either the pleasant or unpleasant odor.
The researchers then played the distinctive tones to the volunteers while they were awake. What they found was that each tone that had been matched to either a pleasant or unpleasant smell would cause the volunteer to take either a deep or shallow breath depending on which smell the sounds were associated with.

Older Father Pass on More Mutation
A 36-year-old will pass on twice as many mutations to his child as a man of 20, and a 70-year-old eight times as many. Previous studies have shown that a child's risk of being diagnosed with autism increases with the father's age. And a trio of papers published this year identified dozens of new mutations implicated in autism and found that the mutations were four times more likely to originate on the father's side than the mother's.

Anti Earthquake Bed
The Wood Luck bed, created by Shinko Industries in Japan, is designed as a more cost-effective means of making a home earthquake resistant. At least it's cost effective when compared to renovating the entire structure, since the cheapest version of the bed starts at a hefty $5,600. They're made from 30 to 40 year old cypress wood that's known for being incredibly strong, which probably contributes quite a bit to the price. But if you had to choose between resting your head on an Ikea bed or this during an earthquake, that price tag starts to seem a lot more reasonable. Although, it's probably most effective for those living on the first floor of a home, or in a basement apartment

Huge Bug Zapper
This device works by providing two energized grids. When an insect flies between the grids it allows the potential energy to overcome the air resistance by travelling through the insect’s body. The zapper uses a transformer from a microwave oven to source that potential. The transformer produces 2.4 kV and the current is limited by a floodlight fitted inside the microwave. The side effect of using the lamp as a limiter is that it lights up with each bug zapped, providing a bit of a light show.

IOS Vulnerability in An SMS
In the text payload, a section called UDH (User Data Header) is optional but defines lot of advanced features not all mobiles are compatible with. One of these options enables the user to change the reply address of the text. If the destination mobile is compatible with it, and if the receiver tries to answer to the text, he will not respond to the original number, but to the specified one. Most carriers don't check this part of the message, which means one can write whatever he wants in this section: a special number like 911, or the number of somebody else. It's been a problem since the iPhone first came out five years ago.

Google's Dremel
Dremel is a way of analyzing information. Running across thousands of servers, it lets you “query” large amounts of data, such as a collection of web documents or a library of digital books or even the data describing millions of spam messages
Dremel can handle web-sized amounts of data at blazing fast speed. According to Google’s paper, you can run queries on multiple petabytes — millions of gigabytes — in a matter of seconds.
According to Google’s paper, the platform has been used inside Google since 2006, with “thousands” of Googlers using it to analyze everything from the software crash reports for various Google services to the behavior of disks inside the company’s data centers. Sometimes, the tool is used with tens of servers, sometime with thousands.
You can use Dremel today — even if you’re not a Google engineer. Google now offers a Dremel web service it calls BigQuery (https://developers.google.com/bigquery/). You can use the platform via an online API, or application programming interface. Basically, you upload your data to Google, and it lets you run queries on its internal infrastructure.

DDoS Hijacking Manual
Turning the tables on miscreants who paralyze websites with torrents of junk data, security researchers have published a detailed manual that shows how to neutralize some of the Internet's most popular denial-of-service tools.
The do-it-yourself how-to provides instructions that even hacking novices can follow to exploit critical vulnerabilities in "Dirt Jumper," a family of tools used to wage the crippling denial-of-service attacks.

Kids With Cavities Do Worse in School
According to a recent study from USC's Ostrow School of Dentistry, kids whose mouths are riddled with cavities do significantly worse in school than their cavity-free peers. Children in the Los Angeles School District who were experiencing tooth pain were four times more likely to have a GPA that fell below the 2.8 median.
The study also found that tooth trouble leads to more sick days, with elementary school students suffering from toothaches missing an average of six more days annually, and high school students missing about 2.6 more days. About 11 percent of students lacking accessible dental care missed school because of toothaches, compared with only four percent who had access to a dentist.

BCG Cures Other Disease
BCG is first and foremost the world's most common tuberculosis vaccine, and was first used in humans all the way back in 1921. Made from a weakened strain of live bovine tuberculosis bacteria, it's been show to be up to 80 percent effective in preventing TB for a duration of 15 years.
As far back as 1979, a clinical trial declared that "BCG is beneficial in the treatment of lung cancer" (http://jjco.oxfordjournals.org/content/9/1/19.abstract). Then, in 1991, a study published in the new England Journal of Medicine suggested that the BCG vaccine offered strong protection against the recurrence of bladder cancer. (http://www.nejm.org/doi/full/10.1056/NEJM199110243251703#t=article+Conclusions)
There followed a 1994 trial which provided evidence that BCG increased survival time and reduced risk of recurrence in those suffering from malignant melanoma (http://lib.bioinfo.pl/pmid:16538310); reports that it was beneficial in the treatment of colorectal cancer (http://www.expert-reviews.com/doi/abs/10.1586/14760584.4.3.329); and, most recently, concrete examples of its beneficial effects in bladder cancer treatment(http://www.nejm.org/doi/full/10.1056/NEJM199110243251703). TB, dead. Four disparate types of cancer kept in check.
In 1999, it was demonstrated that BCG reduced the incidence of MS symptoms (http://www.ncbi.nlm.nih.gov/pubmed/10534275). A 2006 paper in the Lancet explained how BCG has a protective effect on leprosy (http://www.sciencedirect.com/science/article/pii/S1473309906704121). Several years ago, Harvard professor Denise Faustman showed that BCG could be used to treat diabetes in mice (http://www.dailymail.co.uk/health/article-534410/Human-trials-begin-diabetes-cure-terminally-ill-mice-returned-health.html).

Brain Eating Amobas
Back in December, authorities learned that Naegleria fowleri — a deadly, brain-eating amoeba, was living in Louisiana tapwater, infecting its victims' grey matter by way of neti pot (http://abcnews.go.com/Health/Wellness/fatal-infections-linked-neti-pots/story?id=15170230)
The amoeba makes its way to the brain via the olfactory nerves, which it accesses when water is forced up the nose. Anything you do to reduce the risk of water being forced up your nose, probably reduces the risk of infection. If you do go in the water, don't submerge your head, or — if you do — to hold your nose, or wear a nose clip.

Triclosan Impair Muscle Funtion in Humans
Most anti-bacterial soap contains triclosan.
Research published in the Proceedings of the National Academy of Sciences suggests that triclosan hinders human muscle contractions at the cellular level, as well as inhibiting muscle function in both fish and mice.
"Triclosan is found in virtually everyone's home and is pervasive in the environment. These findings provide strong evidence that the chemical is of concern to both human and environmental health."
The mice showed reductions in heart muscle function by as much as 25 percent, and a reduction of grip strength of 18 percent. The fish became less effective swimmers after exposure to triclosan.

Jaguars, Tapirs, Giant Anteaters and Spider Monkeys Have Become "Virtually Extinct" in Brazil's Atlantic Forest
Jaguars, tapirs, giant anteaters and spider monkeys have become "virtually extinct" in Brazil's Atlantic forest, while other species are being lost faster than previously believed due to the fragmentation and emptying of the once dense canopy by farmers and hunters, according to research published.
About 90% of the original Atlantic forest, which once covered an area of about 1.5m km sq (about six times the size of Britain) has been converted to agriculture by cattle ranchers, cocoa farms and rubber plantations.

Tobacco Packaging
Australia's highest court has endorsed cigarette plain-packaging laws that will force tobacco companies to remove branding from their products.
The court found Australia's laws to force companies to remove all branding and sell tobacco only in generic olive green packets, which also carry graphic health warnings, were legal and did not breach trademark rights.
The laws, the toughest in the world, are in line with World Health Organisation recommendations and are being watched closely by Britain, Norway, New Zealand, Canada and India, which are considering similar measures.

Researchers : World-class cryptos wanted
Researchers have renewed their call for help in cracking an "encrypted warhead" they believe it was unleashed by a powerful nation and may be poised to search and destroy a high-profile target.
The mysterious payload is contained in "Gauss," the malware with ties to Stuxnet and Flame that Kaspersky Lab researchers recently found. The researchers believe the secret code may be designed to disrupt SCADA (supervisory control and data acquisition) systems used to control equipment used by dams, gasoline refineries, and other types of critical infrastructure.

Egg Yolks are Almost as Bad for Your Arteries as Smoking
"Because egg yolks are high in cholesterol, eating whole eggs increases cholesterol, a known risk factor for coronary artery disease (CAD) and heart attacks."
"Aging was associated with a linear increase in arterial plaque after age 40, but smoking and egg consumption were each independently associated with an exponential increase in plaque. Egg consumption had two-thirds of the effect of smoking."

The First Five Seconds Can Tell When Someone is Lying
How to :
1. Look for deceptive behaviors and responses within the first five seconds after asking a question.
2. If what they say is the truth, they will say immediately and plainly that they did not commit the crime.
3. Liars often respond to questions with truthful statements that cast them in a favorable position.
4. Liars often repeat a question to stall for time.
5. Nonverbal cues to lying include hiding the mouth or eyes, throat clearing or swallowing, grooming gestures like adjusting shirt cuffs, shifting weight around and sweating.
6. Liars often go into attack mode against the questioner or butter up the questioner with compliments.

Laser Improve Rocket Aiming
The APKWS (advanced precision killing weapon system ?) isn't like other add-on guidance systems. Rather than being embedded in the nose of the rocket, the APKWS installs between the warhead and rocket motor. This installation doesn't require specialized training or tools, meaning that crews can easily add this capability in the field. The system employs the Distributed Aperture Semi-Active Laser Seeker (DASALS), BAE's proprietary guidance method which mounts fiber-optic sensors on the rocket's pop-out fins. This is done so that multiple guided rockets can be fired at the same time. See, if you try to rapid-fire multiple guided missiles, there's a good chance the rockets in the back of the pack will be damaged by the soot, the flames, the heat, or the chop of the lead rockets. By placing the guidance system further back, more rockets can be fired more quickly and with less interference. What's more, the APKWS can also aim itself autonomously or be guided into its target with a laser designator.

Digia to acquire Qt business from Nokia
Finnish software company Digia announced today that it is acquiring the Qt software business from Nokia. Digia plans to pick up where Nokia left off: continuing Qt development, renewing the toolkit’s focus on cross-platform support.
Qt is an open source software development toolkit that was originally created by Norwegian software company Trolltech. Nokia acquired Trolltech in 2008 and subsequently transitioned Qt to an open governance model and a more permissive licensing scheme. Nokia had originally intended to use Qt to provide a unified development framework that would work across Symbian and MeeGo.
Digia says that it’s going to bring back a strong focus on the desktop and will introduce support for Windows 8. The company will also expand official support for the toolkit to additional mobile platforms, including Android and iOS

Nonprobative photographs (or words) enhance our sense that a statement is true
The authors, based in New Zealand and Canada, performed an "alive or dead" test, showing the names of minor celebrities and asking undergraduates whether the person was still alive. In half the cases, they also showed a photo of the person. When the photo was present, people were more likely to answer that the statement was true.

How to Avoid Getting Redirected to Country-Specific Versions of Google
All you need to do is head to www.google.com/ncr. The NCR stands for "No Country Redirect", and it'll take you back to the regular, English-speaking Google.com without all the local results. Note that it will redirect to Google.com, so if you don't see the /ncr after you press Enter, that's normal.

Remember More Without Trying Too Hard
You'll need to do three things when studying or learning a new skill:
1. Give your mind a ton of material: This might seem obvious, but immersing yourself completely in what you're trying to learn is the first step to actually learning it. You don't have to actively try to memorize things, just expose yourself to the skill or material as much as possible.
2. Practice: We tend to stop practicing a skill or stop studying when we think "we've got it." However, well after we learn something we still continue to refine that skill.
3. Sleep: It's thought that sleep is essential to learning and remembering. Some studies have suggested that the brain identifies patterns in our memories and consolidates them to make them permanent when we're sleeping. In essence, a good night of rest might be better than an all-night study-fest.

How Much Sleep Do You Really Need to Work Productively?
*One of the most acclaimed sleep researchers, Daniel Kripke, said there's never been any evidence to back the 8-hour rule. In his most recent study, Kripke found that "people who sleep between 6.5 hours and 7.5 hours a night, live the longest, are happier, and most productive."
*What's even more interesting here is that sleeping longer than that might actually be worse for your health.

Sonic Bug Repellants Don’t Work, So Stop Buying Them
Dr. Roger Gold, a professor of etymology at Texas A&M University, says that "based on the testing we have done through the years, the claims of repelling insects [with sound] are unfounded." His tests included putting insects inside boxes and blasting them with different kind of sonic devices (ultrasonic, subsonic, audible, etc.) and none of them did anything to the bugs.
