- Swimming Robotic Microscallops (Nature) — blood, and indeed most of the internal fluids, is non-Newtonian, which works nicely with the simple reciprocating motion that basic robot actuators generate. Best headline and readable coverage in IEEE, and the best headline: Robotic Microscallops Can Swim Through Your Eyeballs.

How do we motivate sustained behavior change when the external motivation disappears—like it's supposed to?
If you’ve ever tried to count calories, go on a diet, start a new exercise program, change your sleep patterns, spend less time sitting, or make any other type of positive health change, then you know how difficult it is to form new habits. New habits usually require a bit of willpower to get going, and we all know that that’s a scarce resource. (Or at least, a limited one.)
Change is hard. But the real challenge comes after you’ve got a new routine going—because now you’ve got to keep it going, even though your original motivations to change may no longer apply. Why keep dieting when you no longer need to lose weight? We’ve all had the idea at some point that we really should reward ourselves for that five-pound weight loss with a cupcake, right?
When the death of trust meets the birth of BYOD
Dr. Andrew Litt, Chief Medical Officer at Dell, made a thoughtful blog post last week about the trade-offs inherent in designing for both the security and accessibility of medical data, especially in an era of BYOD (bring your own device) and the IoT (internet of things). As we begin to see more internet-enabled diagnostic and monitoring devices, Litt writes, “The Internet of Things (no matter what you think of the moniker), is related to BYOD in that it could, depending on how hospitals set up their systems, introduce a vast array of new access points to the network. … a very scary thought when you consider the sensitivity of the data that is being transmitted.”
As he went on to describe possible security solutions (e.g., store all data in central servers rather than on local devices), I was reminded of a post my colleague Simon St.Laurent wrote last fall about “security after the death of trust.” In the wake of some high-profile security breaches, including news of NSA activities, St.Laurent says, we have a handful of options when it comes to data security—and you’re not going to like any of them.
Mature Engineering, Control Theory, Open Access USA, and UK Health Data Too-Open?
- On Being a Senior Engineer (Etsy) — Mature engineers know that no matter how complete, elegant, or superior their designs are, it won’t matter if no one wants to work alongside them because they are assholes.
- Control Theory (Coursera) — Learn about how to make mobile robots move in effective, safe, predictable, and collaborative ways using modern control theory. (via DIY Drones)
- US Moves Towards Open Access (WaPo) — Congress passed a budget that will make about half of taxpayer-funded research available to the public.
- NHS Patient Data Available for Companies to Buy (The Guardian) — Once live, organisations such as university research departments – but also insurers and drug companies – will be able to apply to the new Health and Social Care Information Centre (HSCIC) to gain access to the database, called care.data. If an application is approved then firms will have to pay to extract this information, which will be scrubbed of some personal identifiers but not enough to make the information completely anonymous – a process known as “pseudonymisation”. Recipe for disaster as it has been repeatedly shown that it’s easy to identify individuals, given enough scrubbed data. Can’t see why the NHS just doesn’t make it an app in Facebook. “Nat’s Prostate status: it’s complicated.”

- A Cyber Attack Against Israel Shut Down a Road — The hackers targeted the Tunnels’ camera system which put the roadway into an immediate lockdown mode, shutting it down for twenty minutes. The next day the attackers managed to break in for even longer during the heavy morning rush hour, shutting the entire system for eight hours. Because all that is digital melts into code, and code is an unsolved problem.

A video interview with Colin Hill
Last month, Strata Rx Program Chair Colin Hill, of GNS Healthcare, sat down with Dr. Dennis Ausiello, Jackson Professor of Clinical Medicine at the Harvard Medical School, Co-Director at CATCH, Pfizer Board of Directors Member, and Former Chief of Medicine at the Massachusetts General Hospital (MGH), for a fireside chat at a private reception hosted by GNS. Their insightful conversation covered a range of topics that all touched on or intersected with the need to create smaller and more precise cohorts, as well as the need to focus on phenotypic data as much as we do on genotypic data.
The full video appears below.
There is a storm brewing in Healthcare. Doctors have been in charge of healthcare for a long time, and have become comfortable, sometimes even arrogant, with their authority and power. But dumb data beats smart doctors every time. Forward thinking doctors are embracing data, with surprising grace and humility. Others are having much more trouble adjusting.
Doctors, historically, have been the “end of the discussion” on clinical matters. Doctors make the diagnosis, they make the calls in the surgery suite, they get to decide if someone is suffering enough to justify pain medications, they frequently decide whether someone is mentally incompetent or merely eccentric. Our society places a lot of trust in doctors, because they have the training needed to make really hard choices.
Doctors, as a group, have been in charge of how healthcare operates for centuries. In times past, the only way to determine whether a doctor was doing a good job was to become a doctor yourself, and then perform case reviews. Even in court, if you wanted to refute a doctor, you needed another doctor.
