This is not really news. The terminal has an instant messenger application built into it. If you have a buddy list with the users in question in it, you can see without doing ANYTHING whether or not that user is signed into their terminal. Furthermore, even if you are not using the instant messenger, you can always do the equivalent of a "whois" search for a user and it will tell you their status. As far as determining the functions a user is using, that is due to the analytics department whose function it is to assist users with obtaining information and helping them use various functions of the terminal. Not sure why the news division had access.

There are going to be a lot of patents that neither Apple or Google really care about in that portfolio, but people in film photography might. First and foremost in my mind is the proprietary dyes used in processing Kodachrome film, which Kodak stopped manufacturing years ago, and the last processor, Dwayne's Photo in Kansas stopped processing at the end of 2010. It would sure be *not evil* to release these formulas to the public, and perhaps we could see something like the group who reproduced polaroid film.

Ok, now I am gnashing my teeth

Let the wailing and gnashing of teeth begin! Then again, it couldn't be worse than episodes 1 and 2.

Basal cell carcinomas are very slow growing, very, very rarely invasive, and almost hardly metastasize. They're gross, unsightly and unpleasant, but not really a killer. If this were melanoma on the other hand, that'd be a big deal.

Well, that'll handle the trach, but if you can do an open appy with a pen and a knife, I'd be seriously impressed. Anyway, the "black bag" includes drape, sterile gloves, scalpel (he later explained how to get those onto planes), basic surgical tools, 3 different IV antibiotics, strong narcotic analgesics (he was less forthcoming about these), and a variety of other things, for various contingencies. There are a number of issues with operating in free-fall, dealing mostly with positioning, and being unable to get gravity assisting you in moving viscera and blood around. I would thing sterility would be a somewhat lesser concern that could be addressed with draping and antibiotics. Of course, figuring out which other astronaut gets to be your scrub nurse is a whole different story. In any case, anything beyond the most minor of surgeries is pretty much going to be off the table (zing!).

I have to ask, why not just send a physician along to any long term deep space mission? There are 5 aerospace medicine residency programs in the country, not to mention the fact that anyone applying for the astronaut positions at NASA gets credited with "work experience" for having completed an MD degree. I believe there are even a few currently active astronauts who are physicians. There isn't much substitute for someone who actually knows what they're doing, and as a (near legendary) trauma surgeon/professor at my medical school is fond of repeating, you can pack a "black bag" with about 10 pounds of equipment that will have you ready for just about anything in the woods, from a emergency tracheostomy to an open appendectomy.

They were simply the fastest cells that were among those that were raced; many cells from various species of protists, not to mention sperm cells are capable of faster speeds than that.

Just because an immune response in the form of circulating antibodies from B cells is seen does not mean infection and replication will not occur when a person is exposed to HIV; most people with HIV have high levels of HIV antibodies circulating in their blood, but the rate at which the virus mutates, as well as the fact that the epitopes the body naturally develops immune responses to are "hidden" by the way in which the viral capsular proteins are folded means that the antibodies do little if anything to halt infection. Furthermore, the CD4+ T cells which initiate a more effective immune response are one of the two types of cells the virus infects (the others being macrophages). At this point, the article gives no further details or useful specifics. If they had said they had generated a cytotoxic CD8+ cell response, or perhaps an immune response against one of the conserved regions of the gp120 or gp41 viral receptors, then I'd be interested. Till then, I am going to be quite skeptical about this until they have some efficacy data. (I am a medical student with an MS in biomedical science)

When I worked in IT this site was practically my morning reading. Although you may not be posting stories anymore, hopefully you poke around and comment every once in a while, it'll be priceless to see a "You must be new here" comment on something you write. Best of luck in the future.

You mean apart from every Apollo mission that went translunar?

In children, IQ measures mental age/chronological age. It's useful for assessing developmentally delayed or precocious children. In adults...your mileage may vary.

1) This is precisely the "best" possible way to induce antibiotic resistance. You are basically selecting out the bacteria which are able to tolerate low doses of antibiotic, which are then able to outcompete their more susceptible brethren. The result is the "normal" gut flora of these farm animals now has a built in resistance to that particular antibiotic. 2) The gut flora of these animals is excreted in waste. The mechanisms by which super bugs are created is through transmission of plasmids, bacteriophages, and naked DNA uptake, which many species of bacteria are capable of. (For a new fun threat, see http://en.wikipedia.org/wiki/Vancomycin-resistant_enterococcus ) 3) There is no "therapeutic dose" for healthy animals. Antibiotics are given to animals to increase the rate at which they absorb food. The "normal" state of the lamina propria and mucosa of the gut is a constant state of low level inflammation, which serves as a protection from any bugs that manage to work their way out of the lumen of the gut. Antibiotic use lowers the amount of gut flora, likely leading to a reduction in this inflammation that results in greater absorption of food. I am not aware of a conclusive proof of this, but animals raised in sterile conditions and fed sterilized food support this hypothesis in terms of weight gain and histologic appearance of gut tissue. 4) You don't need all bugs to become super bugs. The majority of bacteria can become much more virulent and resistant to antibiotics. It really only takes one or two, and there are nearly innumerable options that live happily as commensals in either our or other species guts. 5) This is true, but it's not really going to cheer up someone whose opportunistic infection is resistant to antibiotics. Anyway, see #3 for a good idea of the mechanism. It's not a chemical reaction, its a physiologic consequence. FWIW, I am a medical student finishing up microbiology.
