Keep an eye out for them when they are published, I have read the early manuscripts and they are incredibly good. Through Struggle, the Stars by John J. Lumpkin.

On the other hand is Philip Eklund, who provided some scientific details for this website, instead of the other way around. Bad Astronomy - Slate. A new paper just published in the prestigious Astrophysical Journal makes a stunning claim: There are 10 times as many galaxies in the Universe as we previously thought.

At least. The total number comes in at about 2 trillion of them. Now, let me be clear. This doesn’t meant the Universe is 10 times bigger than we thought, or there are 10 times as many stars. I’ll explain—I mean, duh, it’s what I do—but to cut to the chase, what they found is that there are lots of teeny, faint galaxies very far away that have gone undetected. What the astronomers did was look at extremely deep images of the Universe taken in surveys, for example the Hubble Ultra Deep Field.

That’s a lot of galaxies. Surveys like the UDF are limited. The astronomers who did this research had an interesting problem. The answer is two-fold. Those numbers change with distance. At the same time, these faint galaxies are easier to see close to us, and harder farther away.

But the New York Times reports: A review of studies has found that the health benefits of infant male circumcision vastly outweigh the risks involved in the procedure. Actually, it doesn’t. Not at all. The paper is all about the frequency of circumcision in the US; this is the only real data in the paper, and notice that a good chunk of it is speculation. Prevalence of adult circumcision in the United States during the past 6 decades (1948-2010). It does toss in a table purporting to show the tremendous risks of not circumcising baby boys, but this is not new — these are the same sloppy data that the author has been peddling for over a decade. The author is Brian Morris, better known as the Man Who Hates Foreskins. Take that first condition, the likelihood of urinary tract infections. Or look at his claim of much greater rates of HIV infection. Armed with this hunch, rather than set up a website I chose to do some research.

It’s also an argument that can cut both ways. Encyclopedia Astronautica. Wired.com. The Skeptics Society & Skeptic magazine. Scientific American. Science News – Science Articles and Current Events. Journal home : Nature. Yong Yu, Jason C.H.
