chip technology

King offers an analogy: imagine a computer trying to solve a problem is actually trying to navigate a maze. Instead of tracing one path of the maze at a time, DNA could replicate itself at every junction—and at each point in the maze incorporate new information gleaned from solving the previous step. This would let the DNA explore exponentially faster than modern computer processors. Each strand of DNA is a processor, because it’s executing the command of replicating itself with a slight variation, building another processor which can take up its mantle. Unlike our modern computers which utilize processors that are more or less permanent and can run unlimited kinds of code, these are single-use and disposable, the exact opposite.

Is your future work ID a microchip implant in your body? These workers have made the leap.

  • It’s only human, not to mention frustrating, to forget passwords or misplace your phone, keys or work ID. But is implantable chip technology the solution to make life more convenient — and would you allow your employer to implant a tiny chip into your body to transform you into a cyborg of sorts?
  • That’s a question being actively explored at a Swedish company, Epicenter, where workers are already letting their employer implant a tiny microchip — the size of a grain of rice — in their hands. 
  • The chip allows employees to open doors, use technology with ease and even purchase food without having to fumble for key cards, credit cards, phones or passwords. Workers are even hosting implant parties for their newly chipped colleagues. Read more. (4/4/2017 11:45 AM)

Another fine piece of retro computers joins my army! Say hello to Siemens-Nixdorf Scenic Mobile 500! Equipped with Pentium 100 MHz, 40 MB of RAM, 788 MB HDD, Chip & Technologies 65550 1 MB video chip and ESS1888 sound card, it’s a complete beast for DOS and other older OS. One of the downsides is the fact it doesn’t feature any kind of CD-ROM, but at least it has a functioning floppy drive, as well as a serial/parallel port, so I don’t complain this much. Who knows, I might pick up a PCMCIA CD-ROM/PCMCIA-to-SCSI adapter someday.

MS-DOS 6.22 works like a charm, as I suspected it would. The ESS sound card, and its OPL3 clone, sounds as good as the Yamahas I have in my other retro machines (YMF744B in Tecra 8100 and OPL3 SA-x in my oldschool rig). The screen quality is also great, for an old TFT monitor. However, when it comes to the video, this one doesn’t have a built-in BIOS function of screen scaling, so I have to use a small TSR program to force the full screen, otherwise I’d be playing the DOS games in a bit smaller window (the native resolution is 800x600, and the screen is downsized to 640x480).

Just for the kicks I also tried out Windows 3.11, and no problems here as well (though I had to search for appropriate drivers first). Really enjoyed a quick round of SimTower and other Win3.x games.

Overall, just like Tecra 8100, it’s a damn fine machine if you’re looking for an authentic DOS/early Windows experience, but worried about building from scratch and configuring a retro rig by yourself.

Oh and shoutout for @ms-dos5, as I know you like these kind of thingies. ;)

Wave of the future: Terahertz chips a new way of seeing through matter

Electromagnetic pulses lasting one millionth of a millionth of a second may hold the key to advances in medical imaging, communications and drug development. But the pulses, called terahertz waves, have long required elaborate and expensive equipment to use.

Now, researchers at Princeton University have drastically shrunk much of that equipment: moving from a tabletop setup with lasers and mirrors to a pair of microchips small enough to fit on a fingertip.

Txch This Week: Lab-On-A-Chip Gets Big Boost And The Lemon-Shaped Moon

by Annie Epstein

This week on Txchnologist, we felt a tug on our heartstrings when we read about Lyman Connor’s story. After a fall, Connor spent some time in the hospital and met a small boy who had lost his hand. Inspired by the boy’s plight, he set out to make a low-cost, app-controlled bionic hand. The engineering part has been a success. Now he just needs to find the boy again.

A Swiss team is hard at work creating a new way to filter water at the speedy rate of almost a liter per minute. Their personal water treatment technology uses an advanced polymer membrane with nanoscopic pores that block bacteria, viruses and other microbes from passing through. The device screws on to any plastic bottle and can filter 300 liters of contaminated water, one person’s hydration requirements over the course of a year. 

Manufacturing has begun on parts for the world’s largest experimental nuclear fusion reactor, expected to begin operating in 2020. The international project, now estimated to cost around $20 billion to construct, involves cooperation between Europe, the U.S., Russia, Japan, China, South Korea and India. If it works, the reactor is expected to generate 500 megawatts of power, and one gram of hydrogen fuel will generate as much power as eight tons of oil.

Finally, agricultural scientists are making potatoes for Millenials. Using the age-old method of selective plant breeding, researchers are coming out with tubers colored like raspberries and others splashed with purple accents. Move over bland russets, potatoes with flair will be making their way to markets soon.

Now we’re bringing you the news we’ve been following this week in the world of science, technology and innovation.

The Science Behind Patent No. 8977583

Super small yet perfectly poised to outthink chip technology as we know it: Patent No. 8977583 is a highly efficient chip that’s not only built to resemble the brain, but to behave in ways like one too. It all happens through (wait for it) neuromorphic and synaptronic computation – in other words, the actions of a million artificial nerve cells. With this tiny chip, we’ll be able to cram more cognition and processing power into small devices like phones, hearing aids and watches to make them think better, faster and on-the-fly like humans.

How much longer until chip card technology is normalized and people stop feeling the need to comment upon it? Because, no exaggeration, I spend infinitely more time during my shifts now having to feign interest in people’s thoughts on chip cards than I do hearing or talking about anything actually pharmacy-related. And if I have to deal with this beyond the year 2016 my response is going to devolve from a “haha…. I know right…. so weird…” into the most disinterested eyebrow raise you have ever seen in your life.

Complete Medical Checkup On A Chip Gets Closer

by Txchnologist staff

Engineers have demonstrated an inexpensive handheld device that can analyze up to 170,000 different molecules in a blood sample. The stapler-sized unit might one day make a doctor’s office checkup a thing of the past. 

Measuring minute changes in the intensity of light flashed through a sample, the optical lab-on-a-chip could simultaneously investigate levels of insulin in the blood, viruses and disease markers that indicate cancer or other problems. 

“We were looking to build an interface similar to a car’s dashboard, which is able to indicate gas and oil levels as well as let you know if your headlights are on or if your engine is working correctly,” said Hatice Altug, an associate engineering professor at the Swiss Federal Institute of Technology in Lausanne and Boston University, in a statement.

anonymous asked:

Spock beaming down to a planet that expects him to bring his partner for reasons necessary for negotiations. Jim just stands up grinning in a my time has come sort of way as he goes to get matching customised wedding bands

An uncomfortable silence loomed in the captain’s quarters as Jim stared at the blank terminal screen. It persisted for what felt like an eternity while he pondered with pursed lips the additional orders that had just been issued to him from Admiral Komack. Finally, his eyes raised to Spock standing on the other side of his desk, and he got to his feet. He turned off the monitor and then his hands lifted to dock at his hips, just beneath the gold tunic.

Jim leaned his head back, peering at Spock. “Why?” His brows pulled inward, openly expressing his curiosity. “Why does Starfleet insist on complicating this process? I understand this is the way of Bynaus, but to impose that on Federation delegates…”

Spock was standing stiffly with his hands clasped behind his back. Once Jim trailed off, he stepped in. “The Bynars are said to live in pairs from the moment they are born. It appears they are never separated. Perhaps being approached by many will have adverse effects on our diplomatic efforts.”

Jim hummed, letting his eyes wander to the floor in thought for a moment. “Yes, I remember the intelligence report, Mister Spock.” He hadn’t uttered that in annoyance; rather, Jim was more pensive than anything. Their gazes met again. “So, Command believes they would be more receptive to only two of us arriving for the negotiations, instead of our usual team of five. Two on two, then.”

#100Days100Women Day 79: Lynn Conway—revolutionized computer technology and chip design.
Working w/Carver Mead, Conway simplified & demystified the process of silicon chip design, leading to accelerated advancement in the 1980s.
Together they authored the book “Introduction to VLSI Systems”, which was instrumental in thousands of chip designers learning the craft.

Conway also invented a powerful method for issuing multiple out-of-order instructions (DIS) while working at IBM in the 1960s.
Between her work on chip design and DIS, Conway was invaluable in making personal computers what they are today.

For decades Conway’s DIS innovation & early work was uncredited. She had begun gender transition in the late 1960s & was fired for this.
 After transition, Conway returned to the tech industry in “stealth-mode,” at an entry-level position; working her way back up the ladder.
In 1999 Conway came out. Since then she has consulted & advocated for fair hiring and trans rights (& finally received due credit for DIS!)

Laboratory in a Needle Promises Rapid Diagnosis

by Peter Gwynne, Inside Science

Researchers in the U.S. and Singapore have designed a miniature chemistry laboratory inside a needle that could yield almost instantaneous results from routine laboratory tests, potentially accelerating the diagnosis and treatment of medical conditions.

The prototype device, created by miniaturizing existing “lab on a chip” technology, has shown its capability in studies of mice with liver toxicity, a common side effect of cancer chemotherapy in humans.

“It really integrates the whole laboratory process in one testing without any human in between,” said Stephen Wong of Houston Methodist Research Institute and Weill Cornell Medical Center, who created the idea for the new technology.
