...sizeable research fund of $10 million and an 8,000 square-foot lab space to work with. LaBaer, the founder and current director of the Institute of Proteomics at Harvard Medical School, is one of a handful of innovators in the relatively new field of proteomics, the study of protein structure and function. He said that he wanted to accept the offer in order to focus more on his career goal: developing personalized medicine technologies that would allow doctors to treat patients by tailoring medicines to their individual genomes. LaBaer’s research in proteomics is a crucial towards...
...Less studied, though, is the "genetic dillution effect," in which selective breeding to increase crop yield has led to declines in protein, amino acids, and as many as six minerals in one study of commercial broccoli grown in 1996 and '97 in South Carolina. Because nearly 90% of dry matter is carbohydrates, "when breeders select for high yield, they are, in effect, selecting mostly for high carbohydrate with no assurance that dozens of other nutrients and thousands of phytochemicals will all increase in proportion to yield...
...that happens to be exactly why whale became a significant part of the Japanese diet, as a cheap source of protein in the impoverished days following World War II. As the country grew wealthier, however, whale meat grew less popular. Still, Japan (along with Norway and Iceland) continues to hunt and kill whales - more than 800 in the 2006 to 2007 season - and is pushing for an end to the 22-year-old worldwide ban on commercial whaling. While industry supporters contend that it's necessary for food security, today the average Japanese eats a little more than an ounce...
...been 1.5 billion years or more since our ancestors split off from our fungal cousins. How did the genome of our ancestor change so that it could produce two-legged primates? One part of the answer is that mutations over time altered genes that encode proteins, and some of those changes have been favored by natural selection. But that does not mean that our genome - the sum total of our human DNA - is a finely tuned collection of protein-coding genes. In fact, a lot of mutations that all humans carry neither helped nor harmed our ancestors. They spread just...
...metabolite, sarcosine, that was often found at elevated levels in samples taken from patients with advanced prostate cancer but was present in lower levels in samples of healthy tissue. According to the study, scanning for sarcosine proved a more accurate mode of cancer detection than scanning for the PSA protein...
