An international team of scientists has scanned the genomes of 2,504 people from around the world to create the world’s largest catalog of human genetic variation (HGV). The extensive database will help them understand why some people are susceptible to certain diseases.
While scientists around the world continue to debate the use of the CRISPR/Cas9 system, the tool capable of precisely editing DNA on the genomic level, British scientists working at the Francis Crick Institute in London announced today that they have applied for permission from the United Kingdom’s fertility regulator (the UK Human Fertilization & Embryology Authority) to use this technique on viable human embryos. If granted, this would allow them to directly study humans’ earliest stage of development and would mark the first approval by a national regulatory body to employ the CRISPR/Cas9 system on viable human embryos.
It seems like cruel fate that some folks are naturally thin, while others have to work tirelessly to control their weight. But in the future, we may be able to level the playing field, because scientists have just discovered a ‘metabolic master switch’ that determines whether fat-producing adipocytes store or burn energy.
Consider the beefsteak, a naturally bred giant among tomatoes. It grows as big as two pounds. Scientist have now identified a set of genes that gives beefsteaks their size, and it could lead the way to supersizing more fruits.
Biologists just discovered 11 new species of chameleon hiding in plain sight—as chameleons tend to do.
The Minoans Ancient Greece
Archaeologist Manfred Bietak conducted extensive research on ancient Greek civilizations and their connections to ancient Egypt. Bietak unearthed evidence from artwork as early as 7000 B.C. that depicts the early people inhabiting Greece were of African descent.
