DNA strands are tens of thousands of times smaller than a human hair, and researchers think that nanopores will be the new direction for DNA sequencing. By pulling DNA molecules through the tiny pore, they hope that genetic sequences in this cage DNA can be read at the same time. Researchers from Brown University have combined a nanopore with cage DNA that traps and ...
The history of the Caribbean’s original islanders comes into sharper focus in a new Nature study that combines decades of archaeological work with advancements in genetic technology. An international team led by Harvard Medical School’s David Reich analyzed the genomes of 263 individuals in the largest study of ancient DNA in the Americas to date. The genetics ...
A new analysis of ancient genomes suggests that different branches of the human family tree interbred multiple times, and that some humans carry DNA from an archaic, unknown ancestor. Melissa Hubisz and Amy Williams of Cornell University and Adam Siepel of Cold Spring Harbor Laboratory report these findings in a study published in PLOS Genetics. Roughly 50,000 ...
A team of scientists from the U.S. has succeeded in genetically editing the immune cells of cancer patients through CRISPR. The results of the experiments were published in the journal Science, and provide hope that the technique might one day be used in patients to effectively treat cancer. Editing cancer cells “Researchers at the University ...
For most of our evolutionary human history — for most of the time anatomically modern humans have been on Earth — we’ve shared the planet with other species of humans. It’s only been in the last 30,000 years, the mere blink of an evolutionary eye, that modern humans have occupied the planet as the sole ...
Archaeologists learn about the past by piecing together artifacts from material culture: The tools, artwork, and architecture left behind that tell us how ancient humans lived. But imagine being able to study their ancient DNA as well to learn about how different groups of people were related to each other, where they came from, or ...
History can tell us a lot about the Crusades, the series of religious wars fought between 1095 and 1291, in which Christian invaders tried to claim the Near East. But the DNA of nine 13th-century Crusaders buried in a pit in Lebanon shows that there’s more to learn about who the Crusaders were and their ...
The great white shark is one of the most majestic creatures on the planet and has been an apex predator in the waters for a very long time. Recently, a team of scientists from Nova Southeastern University (NSU) cracked the genome of the shark, revealing some amazing secrets that might one day help fight even ...
James Watson, the Nobel Prize winning scientist who uncovered DNA’s double helix structure, has been stripped of honorary titles after suggesting that blacks are less intelligent than whites due to genetic differences. However, it is not as simple as that, and there are many layers to the story, including political correctness, media bias, politics, and ...
Researchers at the University of Michigan Life Sciences Institute and the Howard Hughes Medical Institute have determined how satellite DNA, considered to be “junk DNA,” plays a crucial role in holding the genome together. Their findings, published recently in the journal eLife, indicate that this genetic “junk” performs the vital function of ensuring that chromosomes ...
