Neural Memory Allocation, DoD Synthbio, Sierra Leone Makers, and Complex Humanities Networks

  1. Memory Allocation in Brains (PDF) — The results reviewed here suggest that there are competitive mechanisms that affect memory allocation. For example, new dentate gyrus neurons, amygdala cells with higher excitability, and synapses near previously potentiated synapses seem to have the competitive edge over other cells and synapses and thus affect memory allocation with time scales of weeks, hours, and minutes. Are all memory allocation mechanisms competitive, or are there mechanisms of memory allocation that do not involve competition? Even though it is difficult to resolve this question at the current time, it is important to note that most mechanisms of memory allocation in computers do not involve competition. Does the dissector use a slab allocator? Tip your waiter, try the veal.
  2. Living Foundries (DARPA) — one motivating, widespread and currently intractable problem is that of corrosion/materials degradation. The DoD must operate in all environments, including some of the most corrosively aggressive on Earth, and do so with increasingly complex heterogeneous materials systems. This multifaceted and ubiquitous problem costs the DoD approximately $23 Billion per year. The ability to truly program and engineer biology, would enable the capability to design and engineer systems to rapidly and dynamically prevent, seek out, identify and repair corrosion/materials degradation.

  3. Innovate Salone — finalists from a Sierra Leone maker/innovation contest. Part of David Sengeh‘s excellent work.
  4. Arts, Humanities, and Complex Networks — ebook series, conferences, talks, on network analysis in the humanities. Everything from Protestant letter networks in the reign of Mary, to the repertory of 16th century polyphony, to a data-driven update to Alfred Barr’s diagram of cubism and abstract art (original here).

Inside NASDAQ's Failbook, SimAustralia, Distraction Attraction, and Big Brother Says "Wash Your Hands!"

  1. Facebook IPO Tech Post-Mortem (PDF) — SEC’s analysis of the failures that led to the NASDAQ kicking Facebook’s IPO in the NADSAQ. (via Quartz)
  2. Run That Town — SimCity for real cities, from the Australian Bureau of Statistics and using real census data. No mention of whether you can make your citizens shout “Aussie Aussie Aussie, Oi Oi Oi!” after three cans of lager at an Aussie Rules game. (via John Birmingham)
  3. Maintaining Focus (The Atlantic) — excellent Linda Stone interview. We may think that kids have a natural fascination with phones. Really, children have a fascination with what-ever Mom and Dad find fascinating. If they are fascinated by the flowers coming up in the yard, that’s what the children are going to find fascinating. And if Mom and Dad can’t put down the device with the screen, the child is going to think, That’s where it’s all at, that’s where I need to be! I interviewed kids between the ages of 7 and 12 about this. They said things like “My mom should make eye contact with me when she talks to me” and “I used to watch TV with my dad, but now he has his iPad, and I watch by myself.”
  4. Networked Motion Sensors in Hospital Bathrooms (NY Times) — At North Shore University Hospital on Long Island, motion sensors, like those used for burglar alarms, go off every time someone enters an intensive care room. The sensor triggers a video camera, which transmits its images halfway around the world to India, where workers are checking to see if doctors and nurses are performing a critical procedure: washing their hands. [...] the video monitoring program, run by a company called Arrowsight, has been adapted from the meat industry, where cameras track whether workers who skin animals — the hide can contaminate the meat — wash their hands, knives and electric cutters.

Underground Economy, Continuous Integration, Chinese Cyber-Espionage, Prosthesis From The Future

  1. Using Silk Road — exploring the transactions, probability of being busted, and more. Had me at the heading Silk Road as Cyphernomicon’s black markets. Estimates of risk of participating in the underground economy.
  2. Travis CIa hosted continuous integration service for the open source community. It is integrated with GitHub.
  3. Chinese Cyber-Espionage Unit (PDF) — exposé of one of China’s Cyber Espionage Units. (via Reddit /r/netsec)
  4. $250 Arduino-Powered Hand Made by a Teenthe third version of his robotic hand. The hand is primarily made with 3D printing, with the exception of motors, gears, and other hardware. The control system is activated by flexing a pre-chosen muscle, such as curling your toes, then the movement is chosen and controlled by a series of eyeblinks and an EEG headset to measure brainwaves. The most remarkable part is that the hand costs a mere $250.

Human Genome Doxed, Programmed by Movies, CritterDrones, and Responsive Websites

  1. ENCODE Project — International project (headed by Ewan Birney of BioPerl fame) doxes the human genome, bigtime. See the Nature piece, and Ed Yong’s explanation of the awesome for more. Not only did they release the data, but also the software, including a custom VM.
  2. 5 Ways You Don’t Realize Movies Are Controlling Your Brain — this! is! awesome!
  3. RC Grasshoppers — not a band name, an Israeli research project funded by the US Army, to remotely-control insects in flight. Instead of building a tiny plane whose dimensions would be measured in centimeters, the researchers are taking advantage of 300 million years of evolution.
  4. enquire.js — small Javascript library for building responsive websites. (via Darren Wood)

Reading Minds, Satellites in the Cloud, Units for Risk, and Valuing Autism

  1. Reconstructing Visual Experiences (PDF) — early visual areas represent the information in movies. To demonstrate the power of our approach, we also constructed a Bayesian decoder by combining estimated encoding models with a sampled natural movie prior. The decoder provides remarkable reconstructions of the viewed movies. These results demonstrate that dynamic brain activity measured under naturalistic conditions can be decoded using current fMRI technology.
  2. Earth Engine — satellite imagery and API for coding against it, to do things like detecting deforestation, classifying land cover, estimating forest biomass and carbon, and mapping the world’s roadless areas.
  3. Microlives — 30m of your life expectancy. Here are some things that would, on average, cost a 30-year-old man 1 microlife: Smoking 2 cigarettes; Drinking 7 units of alcohol (eg 2 pints of strong beer); Each day of being 5 Kg overweight. A chest X-ray will set a middle-aged person back around 2 microlives, while a whole body CT-scan would weigh in at around 180 microlives.
  4. Autistics Need Opportunities More Than Treatment — Laurent gave a powerful talk at Sci Foo: if the autistic brain is better at pattern matching, find jobs where that’s useful. Like, say, science. The autistic woman who was delivering mail became a research assistant in his lab, now has papers galore to her name for original research.

“It’s impossible for me to die”

“It’s impossible for me to die”

Julien Smith on the realities of modern safety and our misfiring flinch reflexes.

Julien Smith believes I won’t let him die. The subject came up during our interview at Foo Camp 2012 — part of our ongoing foo interview series — in which Smith argued that our brains and innate responses don’t always map to the safety of our modern world: “We’re in a place where it’s fundamentally almost impossible to…

Statistical Fallacies, Sensors via Microphone, Peak Plastic, and Go Web Framework

  1. Common Statistical Fallacies (Flowing Data) — once you know to look for them, you see them everywhere. Or is that confirmation bias?
  2. Project HijackHijacking power and bandwidth from the mobile phone’s audio interface.
    Creating a cubic-inch peripheral sensor ecosystem for the mobile phone.
  3. Peak Plastic — Deb Chachra points out that if we’re running out of oil, that also means that we’re running out of plastic. Compared to fuel and agriculture, plastic is small potatoes. Even though plastics are made on a massive industrial scale, they still account for less than 10% of the world’s oil consumption. So recycling plastic saves plastic and reduces its impact on the environment, but it certainly isn’t going to save us from the end of oil. Peak oil means peak plastic. And that means that much of the physical world around us will have to change. I hadn’t pondered plastics in medicine before. (via BoingBoing)
  4. web.go (GitHub) — web framework for the Go programming language.

Human Labour, Kinect in Laptops, Web Fonts, and Brain Boosting

  1. Improvisation and Forgiveness (JP Rangaswami) — what makes us human is not repetitive action. Human occupations should require human intellect, and there’s no more human activity than making a judgement call when processes have failed a customer.
  2. Kinect Tech in Laptop Prototypes — “waving your hands around at your laptop” will be the new “bellowing into your walkie-talkie phone”. (via Greg Linden)
  3. Beautiful Web Type — demo page for the best from Google’s web fonts directory. Source on GitHub.
  4. Ethics of Brain Boosting, Discussion (Hacker News) — this comment in particular: in my initial reckless period of self-experimentation, I managed to induce phosphenes by accident — blue white flashes in the entire visual field, blanking out everything else. Both contacts were in the supraorbital region. I ceased my experiments for a while and returned to the literature. And you thought that typo where you accidentally took the database offline was bad ….
