Sea Urchin Surprise

Sea urchin surprise reported in news@nature, and Biology News Net 9 November 2006 and Science, vol. 314, p398, 10 Nov 2006. Scientists have decoded the genome of the California purple sea urchin and have identified 23,300 genes made from 814 million DNA code letters. The scientists were surprised to find 7,077 of the sea urchin […]

RNA Editing Makes Us Human

RNA editing makes us human, suggests a report in New Scientist, 29 January 2005, p13. RNA editing is a process that changes genetic information after it has been copied onto a molecule called messenger RNA, which carries the information to the protein making machinery in the cell. One editing process changes adenosine molecules to inosine. […]

Rice Gene Count

Rice gene count intrigues scientists who have sequenced the genome of the rice plant, according a report in Nature Science Update 5 April 2002. Rice seems to have somewhere between 40,000 and 50,000 genes. This may be more than humans, even though rice plants have one seventh as much DNA as humans. The reason for […]

Resistance Genes Pre-Date Antibiotics

Resistance genes pre-date antibiotics by “millions of years” according to a report in ScienceNOW 25 September 2002. One reason antibiotic resistance spreads so rapidly is that bacteria carry resistance genes on small loops of DNA called plasmids, which they can pass to other bacteria. Many evolutionists have claimed that resistance genes moved from the main […]

Re-designed DNA Doesn’t Fit

Re-designed DNA doesn’t fit, as noted in a brief item in Nature, vol. 440, p604, 10 August 2006. The “D” in DNA stands for deoxyribose, a sugar molecule made from a five sided ring of carbon atoms. Five sided sugars are called pentoses. Most other sugar molecules, such as glucose, are made from six sided […]

Rats and Jellyfish Join Bomb Squad

Rats and jellyfish combine to join bomb squad, as described in an article in New Scientist, 12 May 2007. Scientists at Temple University, Philadelphia are developing an explosive detector using smell receptor proteins found in rats. Smell receptor proteins work by sending electrical signals when certain chemicals attach to them. In animals the electrical signals […]

Quote: Reader’s Digest on Testosterone

“Without Testosterone, humans would essentially revert to the default, which is female. The Book of Genesis is therefore wrong. It isn’t women who are made out of men. Men are made out of women. Testosterone, to stretch the metaphor, is Eve’s rib.” Readers Digest September 2000, USA edition, p. 85 Editorial Comment: The reason the […]

Promoter Regions Explain Ape Human Difference

Promoter regions explain ape human difference, reports an article in ScienceNOW 13 August 2007. Although chimp and human genes are claimed to be 99 percent the same you don’t have to be a biologist to see that chimps and humans are very different. Way back in 1975 Allan Wilson of the University of Wisconsin suggested […]

Polar Bears Were Irish

Polar bears were Irish, according to articles in BBC News 7 July 2011 and ScienceDaily 8 July 2011. Scientists in the UK, Ireland and USA have studied mitochondrial DNA extracted from the teeth and skeletons of 17 Brown Bears that were found at eight cave sites across Ireland. Mitochondrial DNA (mtDNA) is genetic material carried […]

Pigeon DNA Proves Darwin Right

“Pigeon DNA proves Darwin right” claims Nature News 31 January 2013 in a genetic study of pigeon breeds also reported in ScienceNOW 31 January 2013. Charles Darwin spent many years breeding many varieties of pigeons, and wrote about them in Origin of Species. According to Nathan Young, an evolutionary biologist at the University of California, […]
