New study shows that human and chimpanzee DNA are very different

And this new study is from Nature, the prestigious peer-reviewed journal. (H/T Evolution News via Neil Simpson’s latest round-up)

Excerpt:

A Nature paper from January, 2010 titled, “Chimpanzee and human Y chromosomes are remarkably divergent in structure and gene content,” found that Y chromosomes in humans and chimps “differ radically in sequence structure and gene content,” showing “extraordinary divergence” where “wholesale renovation is the paramount theme.” Of course, the paper attributes these dramatic genetic changes to “rapid evolution during the past 6 million years.”

One of the scientists behind the study was quoted in a Nature news article stating, “It looks like there’s been a dramatic renovation or reinvention of the Y chromosome in the chimpanzee and human lineages.” The news article states that “many of the stark changes between the chimp and human Y chromosomes are due to gene loss in the chimp and gene gain in the human” since “the chimp Y chromosome has only two-thirds as many distinct genes or gene families as the human Y chromosome and only 47% as many protein-coding elements as humans.” According to the news piece, “Even more striking than the gene loss is the rearrangement of large portions of the chromosome. More than 30% of the chimp Y chromosome lacks an alignable counterpart on the human Y chromosome, and vice versa, whereas this is true for less than 2% of the remainder of the genome.”

I’m sure this will make it into the public school textbooks and PBS/Discovery Channel documentaries right away. Right! Away!

Why didn’t the media cover the new CDC study on HIV transmission?

Here’s the Center for Disease Control press release.

Excerpt:

A data analysis released today by the Centers for Disease Control and Prevention underscores the disproportionate impact of HIV and syphilis among gay and bisexual men in the United States.

The data, presented at CDC’s 2010 National STD Prevention Conference, finds that the rate of new HIV diagnoses among men who have sex with men (MSM) is more than 44 times that of other men and more than 40 times that of women.

The range was 522-989 cases of new HIV diagnoses per 100,000 MSM vs. 12 per 100,000 other men and 13 per 100,000 women.

The rate of primary and secondary syphilis among MSM is more than 46 times that of other men and more than 71 times that of women, the analysis says. The range was 91-173 cases per 100,000 MSM vs. 2 per 100,000 other men and 1 per 100,000 women.

While CDC data have shown for several years that gay and bisexual men make up the majority of new HIV and new syphilis infections, CDC has estimated the rates of these diseases for the first time based on new estimates of the size of the U.S. population of MSM. Because disease rates account for differences in the size of populations being compared, rates provide a reliable method for assessing health disparities between populations.

I noticed an analysis by Marcia Segelstein of why these numbers are not communicated more widely here. (H/T RuthBlog)

She writes:

In an effort to look at these figures from a purely scientific and public health perspective, let’s substitute smoking and cancer for homosexual sex and HIV.  If the CDC released information which made a direct correlation between smoking and extremely high rates of getting cancer, people would take notice.  The media would write about it.  Public health organizations would make sure the news was spread.  Campaigns would be launched to save lives by discouraging smoking.  Public funds would be spent to deter people from engaging in such dangerous behavior.  Schools would teach children about the dangers of smoking.

Of course, as we all know, that scenario is real.  Because of the now-known dangers of smoking, a warning from the Surgeon General appears on every pack of cigarettes.  Public service ads saturated the airwaves over a period of years discouraging smoking.  The dangers of smoking are a standard part of most health classes in schools.

I really recommend that everyone who is concerned about this issue read Jeffrey Satinover’s “Homosexuality and the Politics of Truth“, which talks about the health risks of certain behaviors. Dr. Jeffrey Satinover has practiced psychoanalysis and psychiatry for more than nineteen years. He is a former Fellow in Psychiatry and Child Psychiatry at Yale University and a past president of the C. G. Jung Foundations. He holds degrees from MIT, the University of Texas, the Harvard University. If you want to change your mind – and your will – on a topic, you study that topic by looking at the evidence from the experts in the field. Dr. Satinover’s book is compassionate and measured. It is a great place to start learning.

No one is trying to make anyone else feel bad by telling them the truth. On the contrary – by telling people the truth and by setting appropriate boundaries, we can protect others from harm. And that’s why everyone needs to be told the truth. We aren’t helping people by hiding numbers like these from them. Speak the truth in love, and let people decide for themselves.

Obama thinks there is a point where you’ve made enough money

We’re not, we’re not trying to push financial reform because we begrudge success that’s fairly earned. I mean, I do think at a certain point you’ve made enough money. But, you know, part of the American way is, you know, you can just keep on making it if you’re providing a good product or providing good service. We don’t want people to stop, ah, fulfilling the core responsibilities of the financial system to help grow our economy.

Oh well. I didn’t really need all that money I earn anyway. I’ll just keep “fulfilling the core responsibilities of the financial system to help grow our economy” and let Obama decide how to spend what I earn. It’s not like I have a family to provide for – that’s the government’s job – and my family has to be equal to everyone else’s, right? That’s fair. Fair for Obama’s Wall Street buddies, teacher union buddies and trial lawyer buddies that helped him to get elected.

Like we found out during the campaign, Obama likes to spread YOUR wealth around. Especially to people who vote for him.
