Comment Re:You mean like Malaria? (Score 4, Informative) 326

For the record, they're targeting Aedes aegypti mosquitoes, not Anopheles which is the species which carries malaria. Ae aegypti carry yellow fever virus, dengue virus chikungunya virus and Zika viruses. Interestingly Ae aegypti are considered invasive species originally native to Asia. So eradicating them, really shouldn't impact the environment.

Submission + - Tesla Enlists Employees to Be 'Full Self-Driving' Beta Testers (bloomberg.com)

quantumghost writes: Elon Musk has asked for Tesla Inc. employees to test what the company has billed as full self-driving capability and is dangling $13,000 in savings to entice them to help.

Musk wrote in an email obtained by Bloomberg News that Tesla needed about 100 more employees to join an internal testing program linked to rolling out the full self-driving capability. Any worker who buys a Tesla and agrees to share 300 to 400 hours of driving feedback with the company’s Autopilot team by the end of next year won’t have to pay for full self-driving — an $8,000 saving — or for a premium interior, which normally costs $5,000, Musk wrote.

I'm sorry, what scare tactics did I refer to? I have not referred to any well publicized and likely misleading sources used by the war on drugs - I have not referenced the usual claims of lowering IQ or as a gateway drug even though it is reported in a peer reviewed journal. I specfically avoided such sources because I knew someone would attempt to discredit them. What I have given you is clinical experience (19 years now) of issues that I have encountered with actual patients that I have treated. I have had people so strung out on drugs that they failed to recognize a decline in their health that made their condition worse. I have stuporous individuals who have serious medical derangements that we could not determine from their history (they weren't able to talk or were exhibiting paranoia) or from physical exam (they were so out of it I couldn't get they to react to any exam or they refused to cooperate with the exam) Related reference here. It is still illegal to drive after using marijuana in Colorado and California.

While an increasing number of states are allowing "medical marijuana", there are very few registered patients in most states ( CA being the exception - and not a surprising one). So yes, most people _still get their drugs off the street_. I will grant you on a second read that one reference was more of a scare position. A better article is here, and also a report form Europe on laced drugs here. And, please, a little more evidence than "snopes" here - one discredited mass media report is hardly adequate evidence. Not related to marijuana, but an extremely interesting story occured in the 1980s about poorly synthesized ecstasy that resulted in several very young people developing a Parkinson's like disease because of a mistake made by the "chemist" . This tragedy had a bright spot: it gave neurobiologists a way to create a model of Parkinson's in lab animals that they had been unable to create before that.

Trust me I know about people doing stupid things. I am a trauma surgeon and nearly half of my patients arrive with drug and or alcohol on their toxicology screen. Verified in the literature here But marijuana use still has dangers associated with it, especially when smoked. It has been linked to several lung diseases, here, and here. So again, please stop referring to marijuana as "safe" or "safer". And if you would please give me a reference or two stating how it is safer, peer reviewed if you would, as I have given you plenty of links to such.

You might have missed the news on CD awhile back, ask your doctor if he/she knows what causes Crohn['s]

This is a very interesting article and they may be on to something, but it is far from the first time Crohn’s disease has been attributed to microbes. They make a good argument, but I don't think that this closes the case yet. They specifically note that this is for "Familial Crohn’s Disease" and not all cases are familial. This was also a study that only looked a 9 family, with an n of 20, so this is not a very large study, and these are likely geographically co-located (but they did not give a lot of data on that). I'll avoid a long history of the disease and just place the gentle reminder that correlation is not causation (and in medicine the level of evidence for proof is often much higher than in other sciences). A lot more research needs to go into this - but investigating the complex relations in the gut biome is probably going to yield some very good insights.

So I'll continue with my standard answer for Crohn's that "we still don't know for sure" - but we're getting closer.

This is not a joke. Try smoking (or vaping, or eating) some marijuana. It tends to relax internal muscles and may help you pass it. At worst, it's a cheap, harmless, fun thing to try before going in for a more complicated, potentially needless procedure.

This is not a joke, this is some of the worst advice. Please stop posting uninformed advice that is more harmful than helpful.

Muscle relaxants (of which marijuana is a poor one) are not useful here and are actually contraindicated. This capsule is not hung up on a sphincter, it is likely caught in a stricture and inhibition of peristalsis is not going to help and may make matters worse.

In addition, by consuming marijuana and getting "high" he or she may miss changes in their condition that indicate that they need to get to the hospital emergently (e.g. abdominal pain indicative of intestinal rupture). If they decide to take themselves to the ED, driving while impaired is illegal in all states not to mention just plain dangerous. Once there, again, being under the influence of a psychoactive drugs they may not give a thorough medical history, or it may alter the physical exam findings, possibly leading to a misdiagnosis (even with EMRs - I have seen this happen). Marijuana may also interact with other more useful medications that need to be given leading to further complications. In addition, diagnostic tests may be delayed as they won't be able to properly consent after consuming an substance that alters cognition. In addition, buying drug on the street is very dangerous because you do not know exactly what you are buying (a pharmacology professor of mine proved this in the 80s) - even marijuana can be laced with even more dangerous substances

In short, please don't self-medicate. This is especially true when you have a complex medical condition. Leave the medical advice to someone who is trained and qualified.

And stop claiming that marijuana is harmless. I see too many people land in our ED as a result of this type of self-medication.

Comment Re:Is the pill magnetic? (Score 1) 183

Maybe you can use some strong rare-earth magnets to help it along?

This is highly unlikely to work. The problem? You think of the intestine as a linear tube from mouth to colon (then anus), but in reality there are many twists and turns in the intestine (which happens in real time - aka peristalsis). So for any placement of the magnet, you are just as likely to hang it up as to move it along - so doing this yourself won't help - and may actually be harmful if the magnet is strong enough and left in one area too long. That being said....someone has already thought of this. But if you look at the article, it looks like a pretty elaborate setup that likely only exists as a handful centers in the world as this would need to be done in real-time with imaging (looks like a mini CT scanner).

After 12 weeks, the likelihood of this passing on its own is virtually nil, so it will need some help. Double balloon enteroscopy (aka push enteroscopy) can be used if not too far in, and is performed at most university/academic medical centers. Other medical options are descried here. A more aggressive, but not maximally invasive choice would be to bring a surgeon into the mix to do a combination of double balloon enteroscopy and a laparoscopy or just plain old laparoscopy.

Best of luck.

Google Unveils 72-Qubit Quantum Computer With Low Error Rates (tomshardware.com) 76

An anonymous reader quotes a report from Tom's Hardware: Google announced a 72-qubit universal quantum computer that promises the same low error rates the company saw in its first 9-qubit quantum computer. Google believes that this quantum computer, called Bristlecone, will be able to bring us to an age of quantum supremacy. In a recent announcement, Google said: "If a quantum processor can be operated with low enough error, it would be able to outperform a classical supercomputer on a well-defined computer science problem, an achievement known as quantum supremacy. These random circuits must be large in both number of qubits as well as computational length (depth). Although no one has achieved this goal yet, we calculate quantum supremacy can be comfortably demonstrated with 49 qubits, a circuit depth exceeding 40, and a two-qubit error below 0.5%. We believe the experimental demonstration of a quantum processor outperforming a supercomputer would be a watershed moment for our field, and remains one of our key objectives."

According to Google, a minimum error rate for quantum computers needs to be in the range of less than 1%, coupled with close to 100 qubits. Google seems to have achieved this so far with 72-qubit Bristlecone and its 1% error rate for readout, 0.1% for single-qubit gates, and 0.6% for two-qubit gates. Quantum computers will begin to become highly useful in solving real-world problems when we can achieve error rates of 0.1-1% coupled with hundreds of thousand to millions of qubits. According to Google, an ideal quantum computer would have at least hundreds of millions of qubits and an error rate lower than 0.01%. That may take several decades to achieve, even if we assume a "Moore's Law" of some kind for quantum computers (which so far seems to exist, seeing the progress of both Google and IBM in the past few years, as well as D-Wave).

Comment Re: Antibiotics (Score 4, Insightful) 146

First, there have been no reported deaths from this infection as per the article, so how exactly is this deadly? Dangerous, potentially deadly? So, please, lets title these articles responsibly. The remainder of this post is not meant to bash the parent, just to define terms and clarify concepts. My opinion is at the end.

Not a doctor, but there is only a little overlap between antibiotics and antifungal medications.

The term antibiotic covers both anti-bacterial agents (e.g. penicillin) used against bacteria, and anti-fungals (e.g. fluconaole/Diflucan), and technically, they also refer to anti-virals (e.g. aciclovir), but in the most common use, antibiotics refer to antibacterials, and never to antivirals. There are no medications that treat both bacteria (prokaryotes [no nucleus]), fungus (eukaryotes [true nucleus]) simultaneously; yes, bleach (sodium hypochlorite) can destroy both, but internal use is discouraged [and as referenced in the wikipedia article, your body's neutrophils (a type of white blood cell - cells that fight infection) uses hypochlorous acid as an antimicrobial . So.....yes and no. [sorry that kept getting longer and longer]

This stuff is resistant to Diflucan (I'm not trying to spell the generic name correctly right now),

Flu con a zole - that's not too hard....Talimogene Laherparepvec...that's hard. :-)

which is often handed out with much less oversight than antibiotics.

Ummm, no. You can get pretty powerful topical antibiotics and topical antifungals over the counter. Fluconazole is an oral antifungal that still requires a prescription (at least in the US and other "responsible" countries).

Any bio-female could probably get a few doses for a yeast infection without seeing their doctor; calling in and asking is all most require since it is a common ailment.

It is a common ailment, but it is also a true infection that can be cultured and proven, and usually requires treatment. (I don't want you to poo-poo this aliment :-), pretty miserably for those afflicted), and unless there is a well established relationship between physician and patient, an exam is required (and strongly encouraged to rule out other more dangerous diagnoses).

The problem is that many primary care doctors have been told that C. albicans (the common human strain) can not become resistant. I was told the same, only to be corrected by a very indignant Tropical and Infectious Disease specialist who had seen that first line drug become useless in a few cases.

I see fluconazole resistant candida albicans frequently (reported 7% resistance rate), but I work at a tertiary care referral center, so YMMV. Never been under the illusion that it could not become resistant. Every organism (meaning microbial species) given enough time and opportunity can become resistant to just about anything.....The only thing that microbial organisms will never become resistant to is fire, well heat anyways (shout out to the the post below).

But this doesn't mean we need to panic and shut down Madagascar. There are other classes of drugs, like the old standby nystatin, and other families of antifungal medications in the larger azole drug category. This should be treatable if caught early. The danger is that drugs like nystatin can not be absorbed so they only treat dermal or gastric infections,

Yes and no...You are quite correct that nystatin is of limited value as it is not systemically absorbed, so for fungemia fungal infections of the blood), it is useless.(sorry, link is likely paywalled for you, my domain is exempt)

while amphotericin B (same class) does kidney damage at the effective dose. So someone who has a systemic infection is going to only have treatments available that cause as much damage as they are trying to prevent. And hospital acquired infections can become systemic very quickly.

There are a few other antifungal agents that are useful, but this bug is showing some concerning resistances. But I think that one of the things pointed out by the original article is that over 75% of these cases were colonizations, not infections. Therefore, the sky is not falling (yet), but increased surveillance on the part of the global healthcare system is warranted. How can you help? Be responsible, please don't demand antibacterials (or antifungals) at the first sign of what is typically a mild viral infection. Why do antibacterials matter? The bacterial colonization of you body is the first line of defense against fungal infections (read the abstract, for a decent in-depth review see this)
