Bioengineer Chris Voigt and his team at the Massachusetts Institute of Technology have hacked a harmless strain of Escherichia coli so that it produces black pigment in darkness or, in red light, remains transparent. The result: an organism that behaves like film.
The NFC / RFID chip is the size of a grand of sand. It’s equipped with a tiny antenna and encased inside a glass capsule to keep it from being disrupted by its fleshy environment. This chip stores 1KB of data and is readable like a key fob by compatible phones, tablets, card readers and the Arduino microcontroller.
“It’s usually used for privacy, but I use it for a public purpose, which is to distribute artwork,” the artist explains. He hovers his Android 1-2cm above the clotted cut, and up pops his favicon, a signature Antonellis gradient gif.
But the hysteria had the desired effect. It blew up Kickstarter’s modus vivendi. Although the company, which takes a 5% revenue cut, let the glowing-plant project proceed, its management has quietly slipped a new no-no into its ever-growing list of prohibitions: “Projects cannot offer genetically modified organisms as a reward.” In the company’s only public comments on the controversy, in an interview with The Verge website, co-founder Yancey Strickler suggested that the change is modest, because it limits only rewards, not projects themselves. But everyone knows that rewards are crucial to success. People don’t want T-shirts of glowing plants. They want glowing plants.
The second prototype of the Gel Integrated System is done. I ran a gel on it (wet tested it) today, and I am happy to say that I am ready to sell, build, and ship the first few units. There are a few minor revisions that will go out in the first few units, like a clear “lid”, and slightly different dimensions for the wire cutouts, but mostly they will be the same as what I tested today.
It is literally impossible to run this box backwards by accident, since you can only put the tray in in one direction. If you wanted to run it “backwards” you could pull the electrodes out and move them to the other side, but otherwise your DNA will always be loaded on the right side. The wells need to be wider and thinner, but setup for this part is slick and simple., and changing the width of the wells is as simple as cutting the comb out of thinner plastic.
Scientists took cells from a cow and, at an institute in the Netherlands, turned them into strips of muscle that they combined to make a patty.
Researchers say the technology could be a sustainable way of meeting what they say is a growing demand for meat.
Critics say that eating less meat would be an easier way to tackle predicted food shortages.
The burger was cooked by chef Richard McGowan, from Cornwall, and tasted by food critics Hanni Ruetzler and Josh Schonwald.
Upon tasting the burger, Austrian food researcher Ms Ruetzler said: “I was expecting the texture to be more soft… there is quite some intense taste; it’s close to meat, but it’s not that juicy. The consistency is perfect, but I miss salt and pepper.”
She added: “This is meat to me. It’s not falling apart.”
The handheld biosensor was developed by researchers at the University of Illinois, Urbana-Champaign. A series of lenses and filters in the cradle mirror those found in larger, more expensive laboratory devices. Together, the cradle and app transform a smartphone into a tool that can detect toxins and bacteria, spot water contamination and identify allergens in food.
It’s a “plant watering alarm” – you set the dry point, then water the plant and then it starts to chirp when the plant dries out. Chirps are rare at the beginning and more frequent when the water level gets really low. It has a LED hooked up as a light sensor, so it does not make noise at night.
To grow the new ear, researchers created a titanium wire frame modeled after the human ear. They filled in the wire frame with collagen taken from cows. In the future, human replacement ears may use collagen taken from the patient, Thomas Cervantes, one of the researchers and a surgeon at Massachusetts General Hospital, told the BBC. The researchers then seeded their scaffold with cartilage cells taken from sheep. …The team created an adult-size ear and implanted it onto a rat. The point of the implantation is to check that the ear doesn’t lose its shape after implantation and healing.
The only problem is that, to get that nice blue sheen, the water has to be constantly in motion. Which is where Rober got the genius idea to make use of a flowing zen fountain. The algae in the water will, unfortunately, eventually run out of energy and thus light, but until that happens, you’ve got yourself a fantastically clever and stunning lamp to light up the night.
This paper presents the design and implementation of a wearable oral sensory system that recognizes human oral activities, such as chewing, drinking, speaking, and coughing. We conducted an evaluation of this oral sensory system in a laboratory experiment involving 8 participants. The results show 93.8% oral activity recognition accuracy when using a person-dependent classifier and 59.8% accuracy when using a person-independent classifier.
There have been several attempts to build and sell gel boxes to DIY biologists. As far as I am concerned, they are all too expensive and too complicated. Lets look at the two products aimed and produced by diy folks: the Iorodeo kit and the no longer available pearl biotech box.
We’ve long known the slime mold can determine the shortest path through a maze, or even model optimal railway systems. Now, a group of researchers has shown these amoeba-like single-cell organisms could be used to build general-purpose computers.
In a paper published last week on the academic research website arXiv, scientists from the University of the West of England confirm Physarum polycephalum slime molds can act as memristors, a new type of resistor, a key component of electrical circuits. The paper has not yet been submitted to any scientific journals.
Memristors, like resistors, regulate the flow of electricity through a circuit, but they can “remember” a particular charge even when it’s turned off. This means they could be used to create more efficient computer memory. HP claims to have built a real-world memristor and has been working to commercialize the technology for the past few years, though some scientists have claimed HP’s inventions are not actually memristors. Others, meanwhile, have looked to biological systems for examples of working memristors.
A pill called the CorTemp Ingestible Core Body Temperature Sensor, made by HQ Inc. in Palmetto, Fla., has a built-in battery and wirelessly transmits real-time body temperature as it travels through a patient.
Firefighters, football players, soldiers and astronauts have used the device so their employers can monitor them and ensure they do not overheat in high temperatures. CorTemp began in 2006 as a research collaboration from the Johns Hopkins University Applied Physics Laboratory and the National Oceanic and Atmospheric Administration.

The Polar Heart Rate Receiver is designed to receive heart beat signals from compatible Polar heart rate sensors such as the T34. Together, the sensor and receiver provides a low-cost and convenient heart rate monitoring system that can be connected to most any microcontroller.
The Heart Rate Receiver is a stand-alone module, with on-board connections for power (3.3 V to 5 V), ground, and signal. It wirelessly interfaces to a compatible Polar coded or uncoded sensor transmitter. The output pin simply pulses high when a heartbeat is detected.
Receives heart beat signals from a compatible sensor transmitter
Indicates a received heartbeat signal using a LOW/HIGH output signal
Wirelessly interfaces to transmitter with a range of up to four feet
For decades, Jeff Hawkins lived a double life, co-founding Palm, the first successful mobile-device company, and studying the brain in his spare time. Free from the traditional constraints of academia, he has been able to range across the field of neuroscience while applying his knowledge of (and funds from) technology endeavors to understanding cognition. He describes his latest venture, Grok (formerly Numenta), as the first step on a new quest for artificial intelligence—one that he hopes will, among other things, lead to the creation of software super-astronomers someday.
