Will the vAMP replace the CD

first_img Citation: Will the vAMP replace the CD? (2008, January 18) retrieved 18 August 2019 from https://phys.org/news/2008-01-vamp-cd.html The vAMP MP3 player by MediaStreet. The new device, called the vAMP (virtual album MP3 player), is like a cross between a CD and MP3. Technically, it´s an MP3 player, but it comes pre-loaded with a particular album, and you buy it in stores. The vAMP doesn´t have a screen, but it has a front sticker containing album art and a back sticker containing the track listing and liner notes. MediaStreet claims that it´s the smallest (0.7 ounces) and thinnest (3 mm) fully functional MP3 player.The vAMP has 1 GB of space, so consumers can add additional songs to the device, as well as transfer the vAMP´s pre-loaded songs to a computer. Consumers will also have access to Beyond.FM and MyDigitialContent.com to download songs.The vAMP has a suggested retail price of $27.99 each (or you can buy a blank vAMP for $19.99). It may be about the cheapest MP3 player you can get, but it´s still quite a bit pricier than a single CD or downloading individual songs. Nevertheless, MediaStreet and the music stores are hoping that the vAMP and a compelling marketing campaign will lure music fans back into stores. Certainly, the device provides a more tangible collectible item than single MP3s. But whether people who already own iPods will be interested remains to be seen.via: ChipChick While some people might argue that the CD has already been replaced by the MP3, music stores want to think otherwise. The digital device manufacturer MediaStreet has recently announced a product that it hopes will replace the CD and get music fans back in stores. This document is subject to copyright.

US Army Invests in Thought Helmet Technology for Voiceless Communication

first_imgIn the future, soldiers may be communicating silently with sophisticated “thought helmets.” The devices would harness a person´s brain waves and transmit them as radio waves, where they would be translated into words in the headphones of other soldiers. Citation: US Army Invests in ‘Thought Helmet’ Technology for Voiceless Communication (2008, September 22) retrieved 18 August 2019 from https://phys.org/news/2008-09-army-invests-thought-helmet-technology.html The US Army has recently awarded a five-year $4 million contract to researchers from the University of California at Irvine (led by UCI´s Mike D´Zmura), Carnegie Mellon University, and the University of Maryland to study the concept. It will likely be a decade or two before the thought helmet becomes a reality, but the rough technology is already under investigation. Researchers have been working on other brain-computer interfaces, such as Emotiv Systems´ brain-wave headset for video games, which is expected to be available commercially next summer.The Army’s version would of course be more sophisticated and reliable than the gaming headset. To make the thought helmet a feasible piece of equipment for soldiers, scientists need to combine advances in computing power together with our understanding of the human brain. At the moment, the thought helmet concept consists of 128 sensors buried in a soldier´s helmet. Soldiers would need to think in clear, formulaic ways, which is similar to how they are already trained to talk. The key challenge to making the system work is a software system that can read an electroencephalogram (EEG) generated by the sensor data, and pick out when a soldier is thinking words, and what those words are. Because the brain is a complex system and generates such large amounts of data, researchers must also make improvements in computing power. Soldiers will also have to be trained to think “loudly” to make it easier for the system to pick out their words from the brain´s background noise. Also, every individual´s EEG signals are a little different, so users and computers will have to be calibrated so that computers recognize each person´s unique mental pattern.In early versions, recipients will most likely hear messages rendered by a robotic voice in their headphones. But the researchers also think it´s possible to render commands in the speaker´s own voice, as well as indicate the location of the speaker relative to the listener.For people concerned about the ethics of the technology, Elmar Schmeisser, the Army neuroscientist overseeing the program, reassures that the technology will not allow mind-reading. As he explains, since every user has to be trained with the system, it would be impossible to use the technology against an individual´s will and without their cooperation. Instead, the researchers are interested in potential civilian benefits. One such application might be a Bluetooth headpiece which could read speakers´ thoughts and transmit them to the person they´re calling – eliminating those loud, one-sided conversations in public. via: Engadget and Time This document is subject to copyright.

Researchers use DNA strands to create nanobot computer inside living animal

first_img Journal information: Nature Nanotechnology Nanomolecular origami boxes hold big promise for energy storage (Phys.org) —A team of researchers at Bar-Ilan University in Israel has successfully demonstrated an ability to use strands of DNA to create a nanobot computer inside of a living creature—a cockroach. In their paper published in Nature Nanotechnology, the researchers describe how they created several nanobot structures using strands of DNA, injected them into a living cockroach, then watched as they worked together as a computer to target one of the insects cells.

Cells carry out elaborate processes by precisely controlling these collisions, but developing artificial machines that can interface with and control such interactions remains a significant challenge. DNA is a natural substrate for computing and has been used to implement a diverse set of mathematical problems, logic circuits and robotics. The molecule also interfaces naturally with living systems, and different forms of DNA-based biocomputing have already been demonstrated. Here, we show that DNA origami can be used to fabricate nanoscale robots that are capable of dynamically interacting with each other in a living animal. The interactions generate logical outputs, which are relayed to switch molecular payloads on or off. As a proof of principle, we use the system to create architectures that emulate various logic gates (AND, OR, XOR, NAND, NOT, CNOT and a half adder). Following an ex vivo prototyping phase, we successfully used the DNA origami robots in living cockroaches (Blaberus discoidalis) to control a molecule that targets their cells. Prior research has shown that DNA strands can be programmable, mimicking circuits and even solving simple math problems. The team in Israel has now extended that work to show that such programmability can be used inside of a living organism to perform work, such as destroying cancer cells.DNA strands can be programmed because of their natural tendency to react to different proteins. In this new effort, the team unwound DNA strands and then tied them together in an origami type box structure. The box was then “filled” with a single chemical molecule. Next, other such objects were created for the purpose of interacting with both the box structure and certain proteins found inside of the cockroach. The whole point was to create multiple scenarios in which the box would open automatically upon colliding with certain proteins. Adding multiple nanostructures allows for increasing the number of possibilities. For example, if the box structure will only open if it encounters three kinds of proteins, one made naturally by the cockroach, and two others carried by two different DNA origami structures. By mixing the combinations, it’s possible to cause the box to open using logic operations such as AND, OR, NOT (where the box will not open if a certain protein is present) etc., and that of course means that computational operations can be carried out—all inside of a living organism.In their study, the researchers filled the origami box with a chemical that binds with hemolymph molecules, which are found inside a cockroach’s version of a bloodstream. All of the injected nanobots were imbued with a fluorescent marker so that the researchers could follow their progress inside the cockroach. They report that their experiments worked as envisioned—they were able to get the box to open or not, depending on the programming of the entire fleet of nanobots sent into the insect on multiple occasions under a variety of scenarios. Cleary impressed with their own results, the team suggests that similar nanobot computers could be constructed and be ready for trial in humans in as little as five years.last_img read more

Marital strain makes women sad men angry

first_imgMen and women have very different emotional reactions to the strain and support they experience in marriage, new research has found.When a marriage has troubles, women worry. They become sad. They get frustrated. For men, it is sheer frustration and not much more, the study said.Looking at sadness, worry and frustration are among the most common negative emotions reported by older adults – the researchers discovered that men and women in long-term marriages deal with marriage difficulties differently. “The men do not really want to talk about it or spend too much time thinking about it,” said Deborah Carr, professor at Rutgers University in New Jersey, US. Also Read – ‘Playing Jojo was emotionally exhausting’“Men often do not want to express vulnerable emotions, while women are much more comfortable expressing sadness or worry,” Carr noted.In the study, 722 married couples were asked how their marital experience and the reactions of their spouse affected them. While talking about issues and offering support makes the wives, who traditionally feel responsible for sustaining the emotional climate of a marriage, feel good, this only frustrated the husbands surveyed. Also Read – Leslie doing new comedy special with Netflix“For women, getting a lot of support from their spouse is a positive experience,” said Carr. The husbands in the study, who more often rated their marriages positively and reported significantly higher levels of emotional support and lower levels of marital strain than their wives, felt frustrated giving as well as receiving support.“Older men, however, may feel frustrated receiving lots of support from their wife, especially if it makes them feel helpless or less competent,” Carr noted.The study was published in the Journal of Gerontology: Social Sciences.last_img read more
