DNA Traces Illegal Ivory Shipments Back to Major CartelsNews
The international trade in elephant ivory has been illegal since 1989, yet African elephant numbers continue to decline. A study reports that DNA test results of ivory seizures made by law enforcement have linked multiple ivory shipments to the same network of dealers operating out of a handful of African ports.READ MORE
Researchers have created a massive database of the changes in gene activity of individual cells in the cerebellum during embryonic development and immediately after birth.READ MORE
The National Institutes of Health announced the launch of a new initiative to help speed the development of cures for sickle cell disease. The Cure Sickle Cell Initiative will take advantage of the latest genetic discoveries and technological advances to move the most promising genetic-based curative therapies safely into clinical trials within five to 10 years.
Combining metabolic and DNA testing approaches is a way forward for newborn screening, false positives reduced by half.READ MORE
Differences in the DNA within the mitochondria, the energy-producing structures within cells, can determine the severity and progression of heart disease caused by a nuclear DNA mutation. A new study found that when a nuclear DNA (nDNA) mutation was combined with different mild variants of mitochondrial (mtDNA) in mice, the severity of heart disease was markedly different.READ MORE
In a new paper researchers report on studies of mice engineered to lack a gene called CMAH, and resulting data that suggest the lost gene may have contributed to humanity’s well-documented claim to be among the best long-distance runners in the animal kingdom.
Obesity and its related ailments like type 2 diabetes and fatty liver disease pose a major global health burden, but researchers suggest in Nature Communications that blocking an RNA-silencing protein in the livers of mice keeps the animals from getting fat and diabetic conditions.
Only very recently were there serious indications that novel protein coding genes might indeed be formed de novo from so-called non-coding DNA, i.e. in parts of the genome that do not produce proteins. Now, for the first time, a new study has examined the earliest stages in the emergence of these de novo genes.
