Patients with the high-dopamine version of the gene felt slightly better after seeing the curt, all-business health-care provider that gave placebo acupuncture. But they were six times as likely to say their symptoms improved with a caring practitioner as those with the low-dopamine gene, who didn't improve much in any group. … [Read more...] about Researchers may have just identified a genetic basis for the placebo effect
In mice, an animal that uses many of the same genes for reproduction as humans, a team of scientists found they could do just that. The MSU researchers created a line of genetically modified mice lacking the PNLDC1 gene, which encodes a protein essential in genomic parasite regulation. Without the gene, development of sperm was hindered, leaving the altered mice with fewer sperm and smaller testicles, making them effectively sterile. The scientists said that the mice experienced no significant side effects. … [Read more...] about Is Genetics the Answer to Birth Control For Dudes?
The new study, while revealing, remains incomplete. It was limited to a very specific population, namely individuals living in Britain. Future research should look to see if these results can be replicated in other parts of the world. Also, studies of the CCR5-delta 32 mutation have been limited to European populations, and its role in the health of Asian individuals is still poorly understood. Finally, while a correlation was found to exist between the mutation and human life expectancy, the exact reason for the increased mortality rate is not known. Obviously, that would be good to know, and a subject worthy of further research. … [Read more...] about CRISPR Baby Mutation Linked to Higher Risk of Early Death
An Associated Press article highlights the work being done by Indiana company AquaBounty with their growing population of modified salmon. While its salmon won’t be fully ready for sale until 2020, AquaBounty is already the first company to receive U.S. approval for consumption of its GMO animals. Its method, which involves changing just one gene, allows the salmon to grow to full size at a rapidly accelerated rate: “To produce its fish, AquaBounty injected Atlantic salmon with DNA from other fish species that make them grow to full size in about 18 months, which could be about twice as fast as regular salmon.” … [Read more...] about Genetically modified salmon could arrive in U.S. restaurants by next year
In September, the U.S. Department of Agriculture gave the green light to a version of the plant Camelina sativa, an important oilseed crop that had been genetically engineered using CRISPR to produce enhanced omega-3 oil. What was interesting about this approval was that the USDA did not ask that the inventors of the plant endure the usual regulatory hoops required to sell biotech crops. The next month, a drought-tolerant soybean variety developed with CRISPR also got a quick pass from the USDA. … [Read more...] about Why CRISPR-Edited Food May Be in Supermarkets Sooner Than You Think
