Biological clock may shut down long-term memory at night , Feb 19
UH Professor Arnold Eskin receives $2.5 million in grants to continue learning, memory research

If you crammed for tests by pulling 'all nighters' in school, ever wonder why your memory is now a bit foggy on what you learned? A University of Houston professor may have the answer with his research on the role of circadian rhythms in long-term learning and memory.

RESEARCHERS PUBLISH FIRST MARSUPIAL GENOME SEQUENCE, May 09
An international team, led by researchers at the Broad Institute of MIT and Harvard, and supported by the National Institutes of Health , today announced the publication of the first genome of a marsupial, belonging to a South American species of opossum. In a comparison of the marsupial genome to genomes of non-marsupials, including human, published in the May 10 issue of the journal Nature, the team found that most innovations leading to the human genome sequence lie not in protein-coding genes, but in areas that until recently were referred to as "junk" DNA.

In a Fox News program author of book ("Politically Incorrect Guide to Global Warming") states that we "have closed down 1/3 of temperature recording stations..." Greenpeace expert denies statement, and says: "We didn't shut down any stations" Who is right? How can one know? Answer: Look up the data. Graphs above from NASA prove the author is correct.

Here is my analysis:

UPDATE 12 April 2007

What about the concern about contaminants like Mercury, Dioxins, and PCBs?

Fortunately, none of the 40 brand names tested by consumer lab had any detectable levels of mercury, and PCBs.  Therefore, I would not worry about ‘mercury poisoning' from taking fish oil. There may be a few reasons for this: #1) mercury concentrates in muscle (fish meat) and not the oils, #2) the distillation process may eliminate it, #3) many fish used for fish oil have very low concentrations and, even salmon, is not amongst the top 5 ‘mercury carrying'  fish species. Nonetheless, you want to avoid mercury whenever possible.

Dioxins and PCBs can be carcinogenic with extended exposure and thus also worth avoiding.  PCBs can be found in farmed fish.  Consumerlab did not find elevated PCBs in the vast majority of brand names they tested.

Cancer and Vitamin D - The Latest Research

"The serum level associated with a 50 percent reduction in [breast cancer] risk could be maintained by taking 2,000 international units of vitamin D3 daily, plus, when the weather permits, spending 10 to 15 minutes a day in the sun," Garland said.
(Journal of Steroid Biochemistry and Molecular Biology)

"We project a two-thirds reduction in incidence [of colorectal cancer] with serum levels of 46ng/ml, which corresponds to a daily intake of 2,000 IU of vitamin D3. This would be best achieved with a combination of diet, supplements and 10 to 15 minutes per day in the sun," Gorham said.
