Are Mastercard paying for the privilege?

I wouldn't be surprised if they are. Of course, they are likely also anticipating that long-term, the flow of cash will turn the other way around.


ACM Blames the PC For Driving Women Away From Computer Science

Guppy Ever-increasing proportion of female physicians (329 comments)

According to this data chart [], about 30% of physicians are female.

As time go on, this will even out. While the ranks of older physicians are male-dominated, females make up just slightly under half the medical school class in the US. In parts of Europe, they already make up the majority:

women make up 54 percent of physicians below the age of 35 in Britain, 58 percent in France and almost 64 percent in Spain, according to the latest figures from the Organization for Economic Cooperation and Development

ACM Blames the PC For Driving Women Away From Computer Science

Guppy Re:What about nursing?? (329 comments)

Because women who want go into medicine end up nurses instead of doctors. This is the result of stereotypes, peer pressure and a largely male establishment.

In 2011-2012, women represented 47.0% of entering students entering medical school, and it's been hovering at just below half (around 47-49%) for the past decade. This value has also been approximately proportional to the gender mix of applicants, which was 47.3% female in 2011-2012.

Study: Seals Infected Early Americans With Tuberculosis

Guppy Tag #WhereIsTheFuckingPaper (74 comments)

Oh, here it is: Pre-Columbian mycobacterial genomes reveal seals as a source of New World human tuberculosis (Paywall -- free Nature summary article here).

Modern strains of Mycobacterium tuberculosis from the Americas are closely related to those from Europe, supporting the assumption that human tuberculosis was introduced post-contact. This notion, however, is incompatible with archaeological evidence of pre-contact tuberculosis in the New World. Comparative genomics of modern isolates suggests that M. tuberculosis attained its worldwide distribution following human dispersals out of Africa during the Pleistocene epoch, although this has yet to be confirmed with ancient calibration points. Here we present three 1,000-year-old mycobacterial genomes from Peruvian human skeletons, revealing that a member of the M. tuberculosis complex caused human disease before contact. The ancient strains are distinct from known human-adapted forms and are most closely related to those adapted to seals and sea lions. Two independent dating approaches suggest a most recent common ancestor for the M. tuberculosis complex less than 6,000 years ago, which supports a Holocene dispersal of the disease. Our results implicate sea mammals as having played a role in transmitting the disease to humans across the ocean.

How To Read a Microbiome Study Like a Scientist

Guppy Re:Home fecal transplant went wrong (53 comments)

While the clinical picture and timing suggests the possibility, it's far from certain that this was a primary infection stemming from his home fecal transplant. I would have liked to see an analysis of anti-CMV IgM titers, although in this case it's also possible that his case was recognized too long afterwards to determine whether or not it was an actual primary infection.

Don't forget the mercury output as well. It's largely thanks to coal that a few pounds of swordfish steaks now contain (on average) as much mercury as a typical CFL bulb, and the level of mercury in our oceans continues to slowly increase over time.

Guppy Re:Different colors (267 comments)

Polycarbonate lenses drive me nuts because their Abbe number is too low; everything looks like an old-school 3-D movie (without looking at it through the red/blue 3D glasses) to me when I wear them.

I think there was some specialty lens company that sold a multi-layer achromatic eyeglass lens, but I believe they have since gone out of business, unfortunately.

The best commonly available material for chromatic dispersion is probably CR-39, followed by Trivex, but the index is too low for very high-powered prescriptions.

Ask Slashdot: Life Beyond the WRT54G Series?

Guppy +1 for router on Uninterruptible Power Supply (427 comments)

I have a Linksys E900 I've been running DD-WRT on for a while, and never had a lick of trouble with it until this week, when the WAN port fried thanks to a power surge (caused by some dumbass with a drill...).

That reminds me, one of the best things you can do for a home router is to put it behind a UPS. I put my father's Linksys wrt54g behind an old APC-300, it was up for over a year continuously afterwards, and only required a reboot when I had to move it around for some maintenance. Even a crappy $25 Belkin can be surprisingly stable when it has a nice clean power supply.

Newly Discovered Virus Widespread in Human Gut

Guppy Physical structure of the phage? (100 comments)

I'm the last author on the paper and it was discovered in my bioinformatics lab in the CS department at SDSU ...

Quick question -- I see from your paper, do you have an idea what it looks structurally? A bunch of media sites have pictures but are using what is obviously stock art (mostly of T-even phages), but from your paper I see that it has no close phylogenetic relationship to known phages (and if your group had e-microscopy or crystallographic data, it would have been in the paper already).

Still, I figured someone skilled in virology might be able to identify some capsid sequences or something, and be able to make a decent guess.

Russian Government Edits Wikipedia On Flight MH17

Guppy Re:cause and/or those responsible (667 comments)

Btw. does anyone here remember the USS Vincennes?

Funny thing, I once bought a used Science Fiction pulp novel from a used book store (up in State College, PA), sometime in the late 90's. Only later did I realize that "USS Vincennes" was stamped on one of the edges, indicating it must have come from some on-board library. It's a small world.

Anyway, to continue with your question -- yes, I remember it pretty well. And there were plenty of talking heads in the media trying to shift some of the blame onto Iran (that it must have been a martyrdom operation where Iran sacrificed it's own citizens to make us look bad, or that Iran shouldn't have operated civilian and military aircraft out of the same airport, or that the pilot should have known better than to fly on a path directly crossing that of a U.S. warship -- all bunk excuses).

But the U.S. government never denied that we were the ones who shot it down, they admitted it quickly and bluntly.

Chinese-Built Cars Are Coming To the US Next Year

At this point, a majority of the apple juice and tilapia we eat in the U.S. is now imported from China -- as well as food additives such as citric acid, sorbic acid, some vitamin additives, and artificial vanilla flavoring.

And while they haven't yet reached a majority market share, frozen spinach, garlic, mushrooms, and cod have large fractions of the supply coming from China.

Human Blood Substitute Could Help Meet Donor Blood Shortfall

Guppy Predicting the next epidemic (172 comments)

Just force all blood donors to get tested for infection, regardless of orientation, then give the clean ones a certfification with expiry. Re-test as required to continue donating.

Back in the 80's, one of the things we learned from the opening stages of the AIDS epidemic is the possibility that a new disease agent will enter the human population, sight unseen. If such a new virus were to appear, it could spread silently for years before being identified (just has HIV did).

It is this risk which had led to the exclusion of the gay population. The elevated risk for HIV infection in that population serves as a marker -- it demonstrates that they have the epidemiological risk characteristics to become the initial host for such a new disease, should it ever appear. By excluding higher-risk groups, the idea is to slow down the opening stages of the next epidemic.

I've always wondered why you couldn't mount cameras on the outside, and instead of using markers, it would track the room itself, like an optical mouse. Processing would add a fair bit of latency, but you're mostly using the information to correct for drift and error in the gyros, right?

HR Chief: Google Sexual, Racial Diversity "Not Where We Want to Be"

Guppy Washington Post Comment (593 comments)

From the Washington Post's Blog section: Eugene Volokh, On google's employee demographics

... non-Hispanic whites are 61 percent of the Google work force, slightly below the national average. (That average, according to 2006-10 numbers, is 67 percent.) Google is thus less white than the typical American company. White men are probably slightly over-represented; assuming that the 30 percent number it gives for women Google employees worldwide carries over to the U.S. (the article gives no separate number for U.S. women Google employees), white men are 42 percent of the Google work force, and 35 percent of the U.S. work force — not a vast disparity.
Indeed, if the goal is “reflecting the demographics of the country” as to race... ...Google can only accomplish that by firing well over three-quarters of its Asian employees, and replacing them with blacks and Hispanics (and a few whites, to bring white numbers up from 61 percent to 67 percent).

Smaller Testicles correlated with Better Parenting Behavior

Guppy Guppy writes  |  about a year ago

Guppy (12314) writes "A recent paper appearing in PNAS (Paywalled) measured Testicular volume and Testosterone levels in fathers of children aged 1-2 years. This information was compared against parenting surveys reported by the children's mothers, as well as MRI imaging of brain activity in the men's Ventral Tegmental Area (VTA), taken while the men were viewing photographs of their children.

The results appeared consistent with past studies hinting of correlation — both Smaller Testicles and lower testosterone levels were found to correlated with both greater reported Nuturing-type behavior, as well as greater stimulated VTA activity. The authors commented that further research was required, given the limited scope of past investigations into the subject, saying "Testicular imaging is sort of a unique niche right now."

Tylenol may ease pain of existential distress, social rejection

Guppy Guppy writes  |  about a year ago

Guppy (12314) writes "Does Tylenol reduce existential distress? Acetaminophen (Paracetamol) has been used to relieve mild-to-moderate physical pain for over a century, yet its actual mechanism of action continues to be debated; modern research has demonstrated an intriguing connection with the body's endocannabinoid system, raising the question of whether it may also have subtle psychological effects as well. A recent paper claims Acetaminophen can alter our response to existential challenge; previous findings have suggested that it may blunt the pain of social rejection as well."

Training an Immune System to kill Cancer: A Universal Strategy

Guppy Guppy writes  |  more than 2 years ago

Guppy writes "A previous story reported widely in the media, and appearing both on Slashdot and XKCD described a novel cancer treatment, in which a patient's own T-cells were modified using an HIV-derived vector to recognize and kill leukemia cells. In a follow-up publication, a further development is described which allows for a nearly unlimited choice of target antigens, broadening the types of malignancies potentially treatable with the technique."
