Beginning musicians think that sheet music contains more information than it does. It’s all they can do to play the notes on the page. Only later do they realize that sheet music is at best a good approximation of what a composer has in mind. Even when they think they’re just playing what’s on the page, their performance is informed by experience not captured in the sheet music.
A decade ago there was a lot of talk of DNA being the blueprint or software of life. But DNA sequences have not been as useful as anticipated. DNA is more like the sheet music of life. The same DNA can be expressed many different ways, just like a piece of sheet music.
Not only is DNA not source code, in a sense even source code is not source code! Source code in the technical sense, a set of computer language files used to build a program, is not source code in the colloquial sense of “everything you need to know.”
Prof. Seyhan's work confirms and strengthens the finding, that just four hours of exposure to RF-EMF disrupts the ability of human brain cells to repair damaged genes. Other new important work from Australia shows damage to human sperm. "We are deeply concerned about what this could mean for public health," noted Prof Seyhan.
"This work provides a warning signal to all of us. The evidence justifies precautionary measures to reduce the risks for everyone of us," says Prof. Wilhelm Mosgoeller from the Medical University of Vienna who has led European research teams, who found that RF-EMF induce DNA breaks. New studies carried out by scientists in Turkey, Russia and Israel, have investigated a variety of biological effects triggered by cell phones. Two years after false accusations against scientists who described DNA breaks, now the recent results finally show, that exposure induced DNA breaks are real.
A failure modes and effects analysis (FMEA) is a procedure in product development and operations management for analysis of potential failure modes within a system for classification by the severity and likelihood of the failures. A successful FMEA activity helps a team to identify potential failure modes based on past experience with similar products or processes, enabling the team to design those failures out of the system with the minimum of effort and resource expenditure, thereby reducing development time and costs. It is widely used in manufacturing industries in various phases of the product life cycle and is now increasingly finding use in the service industry. Failure modes are any errors or defects in a process, design, or item, especially those that affect the customer, and can be potential or actual. Effects analysis refers to studying the consequences of those failures.
Driptech has developed a technology that eliminates the use of complex emitters, cutting the part count for a drip irrigation system dramatically and reducing costs to 1/4 of typical commercial systems. Reducing complexity also improves reliability and ease of maintenance.
In a Driptech system the water is delivered via precisely punched holes in low-cost plastic tubing. This means installation only requires a farmer to roll out the tubing and connect it to a central pipe fed by an elevated container of water.
Driptech has created the simplest, most affordable, and most field-ready drip irrigation system. This provides a cost-effective means for even the poorest farmers to increase their water use efficiency, growing more crops to feed their families and bring to market.
The EnduraLED A21 17-watt uses the company’s high-power, next-generation LUXEON LEDs. This new technology was developed to meet or exceed Energy Star qualifications for an LED-based replacement for the 75-watt incandescent light bulb. The cool thing about it is that the bulbs deliver 1100 lumens with just 17-watts of electricity. They also have a color temperature of 2700k, a color rendering index (CRI) of 80, and a rated life of about 25,000 hours.
The benefits however, don’t stop there. The EnduraLED A21 17-watt could save about $160 per bulb. The bulb will be available in stores during the fourth quarter of 2011 in the US. The initial suggested retail price is $40 – $45. Although higher than standard incandescent and CFL bulbs, the fact that the EnduraLED will save more in terms of energy cost, and lasts 25 times longer than other bulbs makes it definitely worth the price.
A Massachusetts startup called Noblegen is developing a simplified version of nanopore genome-sequencing technology—a technique that promises high speed and low costs but that usually requires complex instruments to carry out. Noblegen, founded last spring, says its technology's ability to directly and rapidly read DNA sequences could make it economically feasible to bring sequencing technology into clinical labs to diagnose cancer and other diseases.
Noblegen CEO Frank Feist says the company's goal is to sequence at a rate of 50 bases per second. The company won't divulge details of its current prototypes, but says the technology could be scaled up to arrays of 400 by 400 nanopores that sequence over 500 gigabases an hour—or about 30 genomes in 15 minutes.
Exome sequencing (also known as targeted exome capture) is an efficient strategy to selectively sequence the coding regions of the human genome to identify novel genes associated with rare and common disorders. Routine whole genome sequencing of large numbers of individuals is still not feasible partly due to the high cost associated with the technique. At present, it is necessary to use an alternative approach, in which certain regions of the genome, such as the “exome”, are targeted, enriched and sequenced, which requires ~5% as much sequencing as a whole genome. The “exome” represents all the exons in the human genome (i.e., the transcribed region of the genome). Exons are short, functionally important sequences of DNA which represent the regions in genes that are translated into protein and untranslated region flanking them (UTR). UTRs are usually not included in exome studies. In total there are about 180,000 exons found in the human genome. These protein coding regions constitute about 1% of the human genome which translates to about 30 megabases (Mb) in length. It is estimated that the protein coding regions of the human genome constitute about 85% of the disease-causing mutations.
In the last few years, robotics researchers have made progress in machine vision, due in part to the falling cost of computer power, and the photo and image resources that can be pulled from the Web and used to train computer vision systems to recognize different objects. However, Brooks says, giving machines more human-like vision remains one of the biggest challenges to the development of more practical robots.
"Perception is really, really hard. For robots, I think it's largely unsolved," says Brooks. "Image-based recognition has worked surprisingly well, [but] it can't do the recognition that a three-year-old child can do."
[Trax] is using a USB GSM modem to take cellphone calls on a PC. He leaves his sim card in this modem so that it can make and receive calls and text messages through your normal telephone number. For some reason, the USB connection only provides control of this modem and doesn’t pass bi-directional audio. To make this happen, he built an audio interface cable using two transformers and a few passive components to connect the modem to the computer’s audio card.
Canon, because scientists at the University of Lincoln have just seized the crown for world's biggest CMOS image sensor with their new Dynamic range Adjustable for Medical Imaging Technology microchip -- or 'DyNAMITe,' for short. Measuring a hefty 12.8 square cm (or about five square inches), DyNAMITe is roughly 200 times bigger than the chips you'd find in most PCs, making it the largest imager ever made on a wafer of standard, eight-inch diameter.
