Kevin Fu is a professor of electrical engineering and computer science at the University of Michigan. He heads a research group on medical-device security, Archimedes, that works to find vulnerabilities in medical equipment. WattsUpDoc, a system that can detect malware on medical devices by monitoring changes in power consumption, is based on his work. Professor Fu has agreed to put down the pacemakers for a moment and answer your questions about his work and medical device security in general. As usual, ask as many as you'd like, but please, one question per post.

In response to both of my previous articles raising questions about the Fifth Amendment, people sent me a link to a famous video titled "Don't Talk To Cops" delivered by Regents University law professor James Duane. Whether his conclusion is correct or not, I think the argument is flawed in several ways. Please continue reading below to see what I think is wrong with his position.

Velcroman1 writes "What if you could build a computer that works just like the human brain? You could invent new forms of industrial machinery, create fully autonomous thinking cars, devise new kinds of home appliances. And a new project in Europe hopes to create a computer brain just that powerful in the next ten years — and it's incredibly well-funded. The Human Brain Project kicks off Oct. 7 at a conference in Switzerland. Over the next 10 years, about 80 science institutions and at least 20 government entities in Europe will figure out how to make that computer brain. The project will cost about 1.2 billion euros — or about $1.6B in U.S. dollars. The research hinges on creating a super-powerful computer that's 1,000 times faster than those in use today."

Hugh Pickens DOT Com writes "Claudia Assis writes that the US will end 2013 as the world's largest producer of petroleum and natural gas, surpassing Russia and Saudi Arabia with the Energy Information Administration estimating that combined US petroleum and gas production this year will hit 50 quadrillion British thermal units, or 25 million barrels of oil equivalent a day, outproducing Russia by 5 quadrillion Btu. Most of the new oil was coming from the western states. Oil production in Texas has more than doubled since 2010. In North Dakota, it has tripled, and Oklahoma, New Mexico, Wyoming, Colorado and Utah have also shown steep rises in oil production over the same three years, according to EIA data. Tapping shale rock for oil and gas has fueled the US boom, while Russia has struggled to keep up its output. 'This is a remarkable turn of events,' says Adam Sieminski, head of the US Energy Information Administration. 'This is a new era of thinking about market conditions, and opportunities created by these conditions, that you wouldn't in a million years have dreamed about.' But even optimists in the US concede that the shale boom's longevity could hinge on commodity prices, government regulations and public support, the last of which could be problematic. A poll last month by the Pew Research Center for the People and the Press found that opposition to increased use of fracking rose to 49% from 38% in the previous six months. 'It is not a supply question anymore,' says Ken Hersh. 'It is about demand and the cost of production. Those are the two drivers."'"

judgecorp writes "The British Government is discussing a role for 4G in the project to extend rural broadband coverage beyond the reach of fiber. There is £250 million of public money to fill in the gaps left by the £530 Broadband Delivery UK (BDUK) program — BDUK's efforts to extend fiber have been criticized because despite promises of a competitive process, all the BDUK money has gone to BT. At a meeting with mobile operators today, the Department of Culture Media and Sport hopes to set up a more competitive 4G fill-in effort."

theodp writes "Q. What do you get when Bill Gates and Rupert Murdoch put their heads together? A. inBloom (aka SLC), the Gates Foundation-bankrolled and News Corp. subsidiary-implemented collaboration whose stated mission is to 'inform and involve each student and teacher with data and tools designed to personalize learning.' It's noble enough sounding, but as the NY Times reports, the devil is in the details when it comes to deciding who sees students' academic and behavioral data. inBloom execs maintain their service has been unfairly maligned, saying it is entirely up to school districts or states to decide which details about students to store in the system and with whom to share them. However, a video on inBloom's Web site suggesting what this techno-utopia might look like may give readers of 1984 some pause. In one scene, a teacher with a tablet crouches next to a second-grader evaluating how many words per minute he can read: 55 words read; 43 correctly. Later, she moves to a student named Tyler and selects an e-book 'for at-risk students' for his further reading. The video follows Tyler home, where his mom logs into a parent portal for an update on his status — attendance, 86%; performance, 72% — and taps a button to send the e-book to play on the family TV. And another scene shows a geometry teacher reassigning students' seating assignments based on their 'character strengths', moving a green-coded female student ('actively participates: 98%') next to a red-and-yellow coded boy ('shows enthusiasm: 67%'). The NYT also mentions a parent's concern that school officials hoping to receive hefty Gates Foundation Grants may not think an agreement with the Gates-backed inBloom completely through."

An anonymous reader writes "The joint team of the Organisation for the Prohibition of Chemical Weapons (OPCW) and the UN said here that the process of destroying Syria's chemical weapons programme began on Sunday." Of note, this linked article on how to destroy the chemical agents safely.

Features of Google's next Nexus phone have finally been outed, along with confirmation that the phone will be built by LG, as a result of a leaked service manual draft; here are some of the details as described at TechCrunch: "The new Nexus will likely be available in 16 or 32GB variants, and will feature an LTE radio and an 8-megapixel rear camera with optical image stabilization (there’s no mention of that crazy Nikon tech, though). NFC, wireless charging, and that lovely little notification light are back, too, but don’t expect a huge boost in longevity — it’s going to pack a sealed 2,300mAh battery, up slightly from the 2100mAh cell that powered last year’s Nexus 4. That spec sheet should sound familiar to people who took notice of what happened with the Nexus 4. Just as that device was built from the foundation laid by the LG Optimus G, the Nexus 5 (or whatever it’s going to be called) seems like a mildly revamped version of LG’s G2."

The Telegraph reports that previously undetected streams of meltwater have been observed beneath the Antarctic ice sheet. "The streams of water, some of which are 250m in height and stretch for hundreds of kilometres, could be destabilising parts of the Antarctic ice shelf immediately around them and speeding up melting, researchers said. However, they added that it remains unclear how the localised effects of the channels will impact on the future of the floating ice sheet as a whole. The British researchers used satellite images and radar data to measure variations in the height of the Filchner-Ronne Ice Shelf in West Antarctica, which reveal how thick the ice is." The paper itself is paywalled, but the abstract is available online.

The partial government shut-down that the U.S. is experiencing right now is about to enter its second week. Various government functions and services have been disrupted (including some web sites, whether it's a good idea or not), and lots of workers on the Federal payroll have been furloughed. But since the U.S. government is involved in so many aspects of modern American life, you don't have to work for the government to be affected by the budget politics at play. So, whether or not you work for the government in any capacity, the question we'd like to hear your answer to is this: What does the shutdown mean to you, in practical terms, whether the effects are good, bad, or indifferent?

Nick Bilton at the New York Times has been writing skeptically for years about the FAA's ban on even the most benign electronic devices during takeoff and landing on commercial passenger flights. He writes in the NYT's Bits column about the gradual transformation that may (real soon now) result in slightly more sensible rules; a committee established to review some of those in-flight rules has recommended the FAA ease up, at least on devices with no plausible negative effect on navigation. From the article: "The New York Times employed EMT Labs, an independent testing facility in Mountain View, Calif., to see if a Kindle actually gave off enough electromagnetic emissions to affect a plane. The findings: An Amazon Kindle emitted less than 30 microvolts per meter when in use. That is only 0.00003 of a volt. A Boeing 747 must withstand 200 volts per square meter. That is millions of Kindles packed into each square meter of the plane. Still, the F.A.A. said “No.” ... But then something started to change: society." Of course, the rules that committees recommend aren't always the ones that prevail on the ground or in the sky.

Despite the number of companies shipping or promising them, smart watches aren't the easiest sell, and Ars Technica's review of Samsung's entry illustrates why. Despite all the processing power inside, the watch is "sluggish" even for the kind of at-a-glance convenience features that are touted as the reason to have a phone tethered to an (even smarter) phone, and for the most part seems to weakly imitate features already found on that phone. There are a few features called out as cool, like a media control app, but for the most part reviewer Rob Amadeo finds little compelling in the Galaxy Gear.

Google is apparently displeased with sites designed to extract money from arrestees in exchange for removing their mugshot pictures online, and is tweaking its algorithms to at least reduce their revenue stream. From the article at The New York Times: "It was only a matter of time before the Internet started to monetize humiliation. ... The sites are perfectly legal, and they get financial oxygen the same way as other online businesses — through credit card companies and PayPal. Some states, though, are looking for ways to curb them. The governor of Oregon signed a bill this summer that gives such sites 30 days to take down the image, free of charge, of anyone who can prove that he or she was exonerated or whose record has been expunged. Georgia passed a similar law in May. Utah prohibits county sheriffs from giving out booking photographs to a site that will charge to delete them. ... But as legislators draft laws, they are finding plenty of resistance, much of it from journalists who assert that public records should be just that: public."
