DailyDirt: Keeping Mosquitoes Away…
from the urls-we-dig-up dept
The Zika virus has highlighted how much some of us hate mosquitoes. These biting insects aren’t just annoying. They also spread horrible diseases. Previously, we’ve mentioned some plans for destroying all mosquitoes, but that’s probably not the most environmentally-friendly way to go about preventing the spread of mosquito-borne infections. Also, some people seem to attract more bites than others, but how well do mosquito repellents actually work, anyway?
- DEET (aka N,N-diethyl-meta-toluamide) is the standard mosquito repellent, but there are a few other active ingredients that work about as well (or better in some cases). Products with picaridin and IR 3535 work about as well as DEET, and the oil of lemon eucalyptus (PMD) is a natural insect repellent that the CDC recommends. [url]
- Another natural mosquito repellent comes from sweetgrass, a plant native to northern North America. Sweetgrass has been tested to work about as well as DEET for at least a few minutes, and researchers are trying to isolate the active ingredients that may keep pesky insects away. [url]
- The use of DDT is controversial for preventing the spread of the Zika virus. The Zika virus doesn’t kill adult humans, so the use of DDT and its effect on human health needs to be considered carefully before spraying it in an untargeted fashion. [url]

DailyDirt: Our Crazy Drone-Filled World
from the urls-we-dig-up dept
If you haven’t seen any tiny remote-controlled quadcopters circling in the air, you might need to get out a bit more. Maybe we shouldn’t get too paranoid about these things, thinking they’re black helicopters for the 21st century, but if you hear constant artificial buzzing noises, perhaps you should start gearing up to defend your home. Drones could be delivering your pizza for dinner someday, but there are all kinds of uses for this technology.
- If you combined enough tiny drone engines together, could you build a 1-man helicopter? Apparently, yes. But it’ll only fly for a few minutes and doesn’t get too far off the ground. It also vaguely looks like a contraption from the early 1900s, and this isn’t the first multi-copter ever flown that we’ve seen. [url]
- Drones can kill a lot of stuff, but how about mosquitoes? Spraying mosquito larvae from quadcopter drones to prevent mosquito growth will be tested this year in Florida — with approval from the FAA. [url]
- Some folks don’t want drones flying all over the place, and Boeing has a laser cannon just for them. Boeing’s Compact Laser Weapon System can shoot down small aircraft from a pretty good distance (as long as you can see your target with binoculars), and it only takes a couple of seconds to set a drone on fire. It’s probably a bit more expensive than a shotgun filled with birdshot, but it’s a lot more accurate and cool. [url]

DailyDirt: Bite Me. No, Wait, Don't…
from the urls-we-dig-up dept
There are thousands of species of mosquitoes. Killing them all might not be advisable, but controlling how they interact with us would be good — so that we can prevent various mosquito-borne diseases. If you hate mosquito bites, check out a few of these links to learn more about your tiny tiny nemeses.
- Mosquitoes seem to like some people more than others, but is that really true? Maybe. And there might be a genetic reason for it. A (small) study of twins showed that mosquitoes didn’t ‘smell’ a difference between identical twins but could for non-identical twins. A genetic explanation of this result isn’t exactly clear yet, but there could be one. [url]
- Mosquitoes might bite (or suck the blood of) people based on the variety of bacteria living on their skin. This preference may correlate with HLA genes that also seem to be involved in body odor differences. [url]
- What can you do to avoid mosquito bites (besides avoiding areas where mosquitoes live)? If you think you can eat garlic and ward them off like vampires, think again. Protective clothing and DEET seem to be the most effective things so far. There are some devices that disperse various chemical repellents that seem to work, too. Lasers, however, are probably not going to be practical for some time. [url]

DailyDirt: Kill All The Mosquitoes
from the urls-we-dig-up dept
Mosquitoes are a serious pest. They spread terrible diseases like malaria and dengue fever, and they’re just generally annoying to people. So it’s no surprise that quite a few methods have been developed to kill them off in significant numbers, if not entirely. There are actually thousands of different kinds of mosquitoes, and some of them are completely harmless to humans. But if we could target just the ones that spread diseases, we could prevent an enormous amount of death and suffering. Is it really safe to drive mosquitoes to extinction? Here are just a few ways we’re trying to do it (regardless of whether we should).
- Mosquito-borne diseases kill about a million people each year and have killed more people than war, cancer or heart disease. Releasing a genetically modified mosquito could push these insects to near extinction, and this appears to be a very effective way to kill off mosquitoes. [url]
- DDT was once the weapon of choice for killing mosquitoes, but these bugs have developed a resistance to DDT and other chemical pesticides. Researchers are learning more about how DDT resistance develops in mosquito populations, but spraying different chemicals might not be the best solution for controlling mosquitoes. [url]
- For a few years, Nathan Myhrvold has been promoting a laser system to shoot mosquitoes. So far, this Death Star for mosquitoes doesn’t seem to be very practical, but zapping insects with lasers is an entertaining idea at least. [url]

Forget The Death-Star Anti-Mosquito Lasers, Here's How Nathan Myhrvold Can Help Tackle Malaria — And Improve His Image
from the really-doing-good dept
Nathan Myhrvold is trying to rustle up a little positive PR for Intellectual Ventures (IV) by appointing a VP of Global Good (although it’s hard to see how anyone lumbered with such a daft job title is going to be taken seriously anywhere.) You can gauge just how touchy Myhrvold is on this topic by his rather waspish response to some commentary on that move.
As Techdirt reported, Myhrvold came up with what he obviously thinks is a winning riposte whenever people criticize IV’s business model based on industrial-scale patent trollery. He asks them: “How big is your malaria project?” His point being that IV does does have a malaria project, so this somehow makes up for all the bad stuff it does. There’s only one slight problem: that project offers little more than fantasy solutions. For example, here are some details from Intellectual Ventures Lab’s malaria page about a cool-sounding “photonic fence” designed to keep out mosquitoes:
> The system would create a virtual fence made out of light — we call it a “Photonic Fence”. Light Emitting Diode (LED) lamps on each fence post would beam infrared light at adjacent fence posts up to 100 feet (30 meters) away; the light would then hit strips of retroreflective material (similar to that used on highway signs) and bounce straight back toward the illuminator. A camera on each fence post monitors the reflected light for shadows cast by a hapless insect flying through the vertical plane of light. > > When an invading insect is detected, our software identifies it by training a nonlethal laser beam on the bug and using that illumination to estimate the insect’s size and also to measure how fast its wings are beating. Using this method, the system can not only distinguish among mosquitoes, butterflies, and bumblebees, but it can even determine whether a mosquito is male or female! (Females are significantly larger than males and have slower wingbeats.) This is useful because only female mosquitoes bite humans.
However impressive all that technology might be, there’s the obvious problem that mosquitoes could just fly over these “photonic fences”. Perhaps conscious of this flaw, the page describes several other equally ingenious — and equally impractical — approaches to tackling malaria including the use of magnets to make mosquitoes explode and an “engineered blood substitute” to draw them away from humans (also useful for regions plagued by vampires, presumably.)
This impracticality rather undermines Myhrvold’s taunting of lesser mortals that don’t have their own malaria project, since his lab projects seem unlikely to make any significant contribution to combatting malaria in the short term, if ever. Clearly, to tackle malaria in real-life situations, what is needed is not some super high-tech approach that looks good in TED talks, but something rather more simple and effective — something like this, perhaps:
> The University of Cape Town’s Science Department believes that it has found a single dose cure for Malaria. > > This was announced by researchers that have been working on this compound, from the aminopyridine class, for several years. Unlike conventional multidrug malaria treatments that the malaria parasite has become resistant to, Professor Kelly Chibale and his colleagues now believe that they have discovered a drug that over 18 months of trials “killed these resistant parasites instantly”.
Unlike potentially blinding lasers, the new compound is claimed to be safe, with no adverse side effects. Of course, lots of clinical tests still need to be run to establish that and its efficacity. Then, a way to manufacture and distribute the drug to malaria victims will need to be found. The worry has to be that traditional drug companies won’t be interested in helping here, since the drug must be sold cheaply if it is to reach the millions of people most affected by malaria, and that means few if any profits — not something pharma companies are happy with.
So here’s a suggestion. If Myhrvold really wants to burnish the image of Intellectual Ventures through philanthropic activities, he should forget about appointing his VP of Global Good, and drop his fun but useless malaria program. Instead, he and his company should offer to pay all the costs for carrying out the clinical tests of this new anti-malarial drug, and for setting up a large-scale manufacturing program sufficient to treat everyone in the world that has the disease, or is at risk from it. Helping to circumvent problems caused by drug companies’ obsession with patents and exorbitant profits would be a truly fitting way to atone for the sins of Intellectual Ventures.

Nathan Myhrvold: It's Ok To Kill Innovation If You're Also Killing Mosquitoes
from the that's-not-how-it-works dept
You may have seen the story last week about how Intellectual Ventures is trying to hire a “VP of Global Good” to take some of IV’s ideas — not a single one of which has ever been brought to market — and see about bringing them to the developing world. Here’s what this is about: every time people talk about Intellectual Ventures and the way it’s put a massive, pointless and wasteful tax on innovation around the globe, IV and its founder Nathan Myhrvold point to their laser mosquito zapper. It’s the go-to talking point. “We’re zapping mosquitoes and stopping malaria.” Except, of course, that the product is just a demo, not anything out in the market. So, the VP of “Global Good” is to try to actually get the product out there and used. Of course, some of us are skeptical as to how effective it really would be, but we’ll reserve judgment there.
That said, Jeff Roberts, over at GigaOm, properly called out Intellectual Ventures for its hypocrisy in calling for “Global Good” when the company’s entire business is focused on screwing over innovators by charging them an often substantial tax by bundling together tens of thousands of broad patents. Roberts notes that anyone taking the job is signing up for a “Faustian bargain.”
The future “VP of Global Good” will be hard-pressed then to carry out enough good works to offset the colossal harm of his or her employer. Unless, of course, they choose to close the company and reform the patent system.
The ever-thin-skinned Myhrvold took exception to that and mocked GigaOm — a company that actually produces something, unlike Myhrvold’s company — because Malaria!
I think we do a whole lot more good for the world than GigaOm does. How big is their malaria research project? How much effort do they put into polio? I’m quite curious! What on Earth have they done that is —
You know, I was at a conference recently where someone said, “Well, do you feel good about what you’re doing?” I turned to this person who is an entrepreneur at a prominent social networking website, and I said, “OK, fine. You’re about people sending little messages to each other and having fun on a social network. How big is your malaria project?”
It turns out it’s very easy if you have a technology-centric mindset to think, Ah yes, Zynga, they’re doing — I don’t mean to call Zynga out in a negative way, but is Zynga doing God’s work? Is Facebook doing God’s work? Even setting aside what God’s work means, I think it’s pretty easy to say, those companies are doing wonderful things, but they are for-profit ventures. It’s either tools or toys for the rich. There really is a role in taking great technological ideas and trying to harness them for the poorest people on Earth.
This is disingenuous to the point of being sickening. IV is very much a “for-profit venture” as well. In fact, if the leaks from the incredibly secretive company, concerning how much they charge companies are accurate, it’s a massively profitable venture. And, if we’re talking about “tools or toys for the rich,” there’s no better example of who Myhrvold is describing… than Myhrvold himself. Remember this is the guy who is selling a $600 cookbook about how to use modern technology to prepare your food.
But this claim — that if you’re not doing anything about malaria, you can’t comment on how harmful Intellectual Ventures is for innovation, the economy and for society — is ridiculous. Roberts, thankfully, hits back hard in a piece entitled, Malaria is no excuse for patent trolling, Mr. Myhrvold. Here’s a snippet:
Well, the sentiment is certainly a noble one. The problem, though, is that Myhrvold is utterly unfit to espouse it. As we’ve stated before, no amount of philanthropy can undo the incredible ruin his company has unleashed on innovation through unfettered patent trolling. Lest you doubt, consider the following:
New research shows that Intellectual Ventures is tied to at least 1,300 shell companies whose sole purpose is to coerce real companies into buying patent license that they don’t want or need. Those who resist the “patent trolls” are dragged into nightmarish lawsuits.
Think what this means in practice. It means thousands of entrepreneurs must divert revenue from development and technology to pay Mr. Myhrvold’s licensing tax or else brace for millions in legal fees. Worse, Intellectual Ventures is targeting some of the most promising young start-ups in the country like hand-craft site Etsy. Now, instead of hiring workers and bolstering the economy, Etsy and others must put aside money to pay for Mr. Myhrvold instead.
And, of course, for all the talk of stopping malaria, the bug zapping demo is just that. It’s a demo. He hasn’t done anything to stop malaria either. He’s produced a fancy demo that the slobbering press loves, so that he can pretend to be doing good for the world, while being the single largest force against innovation in our economy today. The companies Myhrvold is shaking down and suing are producing real products in the real world, not just demanding people pay them or get sued.
Myhrvold is proving himself not to just be a completely obnoxious patent troll with his efforts, but now one who hides behind ridiculous moral relativism to hit back at critics with very real gripes. It’s sickening.
