A new study reveals that our canine pals are capable of copying our behavior as long as 10 minutes after it's happened. The ability is considered mentally demanding and, until this discovery, something that only humans and apes were known to do."

sciencehabit writes "Behind every great man, the saying goes, there's a great woman. And behind every sperm, there may be an X chromosome gene. In humans, the Y chromosome makes men, men, or so researchers have thought: It contains genes that are responsible for sex determination, male development, and male fertility. But now a team has discovered that X—'the female chromosome'—could also play a significant role in maleness. It contains scores of genes that are active only in tissue destined to become sperm. The finding shakes up our ideas about how sex chromosomes influence gender and also suggests that at least some parts of the X chromosome are playing an unexpectedly dynamic role in evolution."

sciencehabit writes "The community of microbes in an animal's gut may be enough to turn the creature into a different species. Species usually split when their members become so genetically distinct — usually by living in separate environments that cause them to evolve different adaptations (think finches on different islands) — that they can no longer successfully breed with each other. Now researchers have shown that a couple groups of wasps have become new species not because their DNA has changed, but because the bacteria in their guts have changed — the first example of this type of speciation."

sciencehabit writes "The newest source of battery power for your cell phone is both cheap and abundant. Scientists report that microbial fuel cells using human urine can directly power a cell phone battery. However, the devices are not quite portable enough to come in handy during a marathon pub crawl. One consists of six, 4-inch-long ceramic cylinders; the other is a network of 25 smaller fuel cells borrowed from the team's waste-fueled EcoBot. And urine-powered conversations would have to be short and sweet. After 24 hours of charging, a Samsung phone stayed alive for 25 minutes—enough to send several texts and make a 6-minute, 20-second call."

sciencehabit writes "When surgeons can't determine the edges of a tumor, it's a problem. Cut too much, and they risk hurting the patient. Cut too little, and they may leave stray cancer cells behind. Now, researchers have developed a surgical knife that can sniff the smoke made as it cuts tissue, almost instantly detecting whether cells are cancerous or healthy. The 'intelligent knife,' or iKnife could distinguish normal and tumor tissues from different organs, such as breast, liver, and brain, and could even identify the origin of a tumor that was a metastasis, a secondary growth seeded by a primary tumor elsewhere in the body."

sciencehabit writes "Europe's first farmers helped spread a revolutionary way of living across the continent. They also spread something else. A new study reveals that these early agriculturalists were fertilizing their crops with manure 8000 years ago, thousands of years earlier than previously thought."

sciencehabit writes "The tragic opera Rigoletto may move you to tears, but here's a more literal application of the moving power of sound. Sound waves with frequencies just above human hearing can levitate tiny particles and liquid droplets and even move them around, a team of engineers has demonstrated. The advance could open up new ways to handle delicate materials or mix pharmaceuticals."

theodp writes "GeekWire reports that HP has named former Microsoft chief software architect Ray Ozzie to its Board of Directors. Ozzie, known for his early work on collaboration technologies including Lotus Notes, has been working on his own startup since leaving Microsoft in 2010. Ozzie recently sounded off on the NSA spygate affair, suggesting it's time to revisit the deal we made with the 9/11-privacy-devil."

An anonymous reader writes "Here is an article by Dr.Joe Stiglitz on how intellectual property reinforces inequality by allowing patent owners to seek rent (aka license / sue) instead of delivering goods to the society. From the article: 'At first glance, the case, Association for Molecular Pathology v. Myriad Genetics, might seem like scientific arcana: the court ruled, unanimously, that human genes cannot be patented, though synthetic DNA, created in the laboratory, can be. But the real stakes were much higher, and the issues much more fundamental, than is commonly understood. The case was a battle between those who would privatize good health, making it a privilege to be enjoyed in proportion to wealth, and those who see it as a right for all — and a central component of a fair society and well-functioning economy. Even more deeply, it was about the way inequality is shaping our politics, legal institutions and the health of our population.'"

Nerval's Lobster writes "For the second time in a month, Hewlett-Packard has been forced to admit it built secret backdoors into its enterprise storage products. The admission, in a security bulletin posted July 9, confirms reports from the blogger Technion, who flagged the security issue in HP's StoreOnce systems in June, before finding more backdoors in other HP storage and SAN products. The most recent statement from HP, following another warning from Technion, admitted that 'all HP StoreVirtual Storage systems are equipped with a mechanism that allows HP support to access the underlying operating system if permission and access is provided by the customer.' While HP describes the backdoors as being usable only with permission of the customer, that restriction is part of HP's own customer-service rules—not a limitation built in to limit use of backdoors. The entry points consist of a hidden administrator account with root access to StoreVirtual systems and software, and a separate copy of the LeftHand OS, the software that runs HP's StoreVirtual and HP P4000 products. Even with root access, the secret admin account does not give support techs or hackers access to data stored on the HP machines, according to the company. But it does provide enough access and control over the hardware in a storage cluster to reboot specific nodes, which would 'cripple the cluster,' according to information provided to The Register by an unnamed source. The account also provides access to a factory-reset control that would allow intruders to destroy much of the data and configurations of a network of HP storage products. And it's not hard to find: 'Open up your favourite SSH client, key in the IP of an HP D2D unit. Enter in yourself the username HPSupport, and the password which has a SHA1 of 78a7ecf065324604540ad3c41c3bb8fe1d084c50. Say hello to an administrative account you didn't know existed,' according to Technion, who claims to have attempted to notify HP for weeks with no result before deciding to go public."

The NY Times reports on a program in use by the United States Postal Service that photographs the exterior of every piece of mail going through the system and keeps it for law enforcement agencies. While the volume of snail mail is dropping, there were still over 160 billion pieces of mail last year. "The Mail Isolation Control and Tracking program was created after the anthrax attacks in late 2001 that killed five people, including two postal workers. Highly secret, it seeped into public view last month when the F.B.I. cited it in its investigation of ricin-laced letters sent to President Obama and Mayor Michael R. Bloomberg. It enables the Postal Service to retroactively track mail correspondence at the request of law enforcement. No one disputes that it is sweeping." This is in addition to the "mail covers" program, which has been used to keep tabs on mailings sent to and from suspicious individuals for over a century. "For mail cover requests, law enforcement agencies simply submit a letter to the Postal Service, which can grant or deny a request without judicial review. Law enforcement officials say the Postal Service rarely denies a request. In other government surveillance program, such as wiretaps, a federal judge must sign off on the requests. The mail cover surveillance requests are granted for about 30 days, and can be extended for up to 120 days. There are two kinds of mail covers: those related to criminal activity and those requested to protect national security. The criminal activity requests average 15,000 to 20,000 per year, said law enforcement officials who spoke on the condition of anonymity because they are prohibited by law from discussing the requests. The number of requests for antiterrorism mail covers has not been made public."

sciencehabit writes "Combining lasers with a principle discovered by Alexander Graham Bell over 100 years ago, researchers have developed a new way to collect high-resolution information about the shape of red blood cells. The lasers pulse every 760 nanoseconds to induce red blood cells to emit sound waves with frequencies of more than 100MHz, one of the highest frequencies ever achieved. Testing the laser on blood samples collected from a group of human volunteers, researchers showed that the high-frequency sound waves emitted by red blood cells in the blood samples revealed the tiniest details about the cells' shapes. Because diseases like malaria can alter the shape of the body's cells, the device may provide a way to accurately diagnose various blood disorders before it's too late." Abstract (actual paper is paywalled).

sciencehabit writes "A patient admitted to a hospital with a serious bacterial infection may have only a few hours to live. Figuring out which antibiotic to administer, however, can take days. Doctors must grow the microbes in the presence of the drugs and see whether they reproduce. Rush the process, and they risk prescribing ineffective antibiotics, exposing the patient to unnecessary side effects, and spreading antibiotic resistance. Now, researchers have developed a microscopic 'tuning fork' that detects tiny vibrations in bacteria. The device might one day allow physicians to tell the difference between live and dead microbes—and enable them to recognize effective and ineffective antibiotics within minutes."

sciencehabit writes "Geoscientists still can't predict when a major quake will strike, and many have given up trying. But many do try to issue more general forecasts of hazards and potential damage. This week, researchers added a potentially powerful new tool to their kit: the largest seismic database of its kind ever constructed, based on tens of thousands of earthquake records stretching back more than 1,000 years. Together with a new global map of strain accumulation at plate boundaries, the data sets will form the core of an international public-private partnership intended to reshape the science of earthquake forecasting."

sciencehabit writes "Scientists have sequenced the oldest genome to date—and shaken up the horse family tree in the process. Ancient DNA derived from a horse fossil that's between 560,000 and 780,000 years old suggests that all living equids—members of the family that includes horses, donkeys, and zebras—shared a common ancestor that lived at least 4 million years ago, approximately 2 million years earlier than most previous estimates. The discovery offers new insights into equine evolution and raises the prospect of recovering and exploring older DNA than previously thought possible."

puddingebola writes "John Morris at CNET offers a brief review of PC Android devices, many of them hybrids running Windows 8 and Android. From the article, 'Microsoft has spent a lot of time and effort trying to get Windows onto smartphones and tablets — so far without a whole lot to show for it. Now several PC companies are trying the opposite approach, taking the Android operating system and porting it to PCs.' The article reviews the recent releases from HP, Acer, Asus, and Samsung. Does Android creeping onto desktop or 'traditional' PC devices have any kind of possible long term consequences? Could this be a way for Android and Google to develop a larger presence in corporate IT, or could Android ever really supplant the Windows foothold?"

wiredmikey writes "Security response personnel at HP are 'actively working on a fix' for a potentially dangerous backdoor in older versions of its StoreOnce backup product line. The company's confirmation of what it describes as a 'potential security issue' follows the public disclosure that malicious hackers can use SSH access to perform full remote compromise of HP's StoreOnce backup systems. The SHA1 hash for the password was also published, putting pressure on HP to get a fix ready for affected customers. SecurityWeek has confirmed that it is relatively trivial to brute-force the hash to obtain the seven-character password. The HP StoreOnce product, previously known as HP D2D, provides disk backup and recovery to small- to midsize businesses, large enterprises, remote offices and cloud service providers."

sciencehabit writes "The next time you hear extended applause for a performance you didn't think was that great, don't feel like a snob. A new study reveals that audience response has more to do with the people in the seats than those up on stage. Applause, it turns out, is a bit like peer pressure. In a study of college students, individuals were more likely to start clapping if a larger percentage of the audience had already started. If 50% of the audience was clapping, for example, individuals were 10 times more likely to start clapping than if 5% of the audience was clapping. People stop clapping for the same reason. Even more surprising, the applause for a bad presentation could be just as long as applause for a good one. Random interactions in the audience can result in very different lengths of applause regardless of the quality of the talk."

Taco Cowboy writes "Most of the younger /. readers never heard of the PDP-11, while we geezers have to retrieve bits and pieces of our affairs with PDP-11 from the vast warehouse inside our memory lanes." From the article: "HP might have nuked OpenVMS, but its parent, PDP-11, is still spry and powering GE nuclear power-plant robots and will do for another 37 years. That's right: PDP-11 assembler programmers are hard to find, but the nuclear industry is planning on keeping them until 2050 — long enough for a couple of generations of programmers to come and go." Not sure about the OpenVMS vs PDP comparison, but it's still amusing that a PDP might outlast all of the VAX machines.

sciencehabit writes "Show a native-born Chinese person a picture of the Great Wall, and suddenly they'll have trouble speaking English, even if they usually speak it fluently. That's the conclusion of a new study, which finds that reminders of our home country can complicate our ability to speak a new language. The findings could help explain why cultural immersion is the most effective way to learn a foreign tongue and why immigrants who settle within an ethnic enclave acculturate more slowly than those who surround themselves with friends from their new country."
