Childhood trauma found to accelerate biological signs of aging

A compelling new meta-analysis from a trio of accomplished psychologists suggests violent or traumatic experiences in childhood can accelerate biological signs of aging. Early puberty, rapid cellular aging, and structural brain changes could all be lin… Continue reading Childhood trauma found to accelerate biological signs of aging

Ancient cave “hotel” places humans in the Americas 30,000 years ago

It’s generally believed that the Clovis people were the first humans to inhabit the Americas, as long as 15,000 years ago. But now archaeologists have found evidence in a cave in Mexico that suggests humans visited as early as 30,000 years ago – althou… Continue reading Ancient cave “hotel” places humans in the Americas 30,000 years ago

Cancer blood test catches disease 4 years before conventional methods

A new cancer-detecting blood test has been found to catch five common types of cancer up to four years before any other conventional diagnostic tool. Further verification is needed before the test is clinically available but the researchers suggest thi… Continue reading Cancer blood test catches disease 4 years before conventional methods

Human X chromosome completely sequenced for the first time

As close as we’ve gotten to sequencing the entire human genome, there are still a few gaps. But now geneticists have plugged a major one in a landmark new study, by sequencing the entire human X chromosome from end to end, covering more than three mill… Continue reading Human X chromosome completely sequenced for the first time

DNA suggests Polynesian and Native American contact pre-European arrival

An archaeological conundrum may have been solved by DNA analyses carried out by a team of Stanford Medicine scientists led by Alexander Ioannidis that indicates Native Americans and Polynesians came into contact centuries before the arrival of the firs… Continue reading DNA suggests Polynesian and Native American contact pre-European arrival

Counting DNA mutations predicts lifespan, raises hopes of reversing aging

New research from the University of Utah Health, published in the journal Scientific Reports, is offering the fascinating suggestion that a person’s lifespan could be predicted at a young age by measuring the volume of genetic mutations they accumulate… Continue reading Counting DNA mutations predicts lifespan, raises hopes of reversing aging

Breakthrough tech makes DNA data storage more practical and scalable

As with many technologies, nature outdid us long ago in terms of data storage – just one gram of DNA can store 215 million GB of data. But artificial DNA data storage systems could soon become more practical, thanks to a new technology named DORIS that… Continue reading Breakthrough tech makes DNA data storage more practical and scalable

Ancient DNA fingerprints help solve the Dead Sea Scroll puzzle

A new study is demonstrating how ancient animal DNA, extracted from Dead Sea Scroll parchments, can help with piecing together the jigsaw puzzle of disparate fragments found in the Judean desert. It’s hoped the novel method will help generate a Dead Se… Continue reading Ancient DNA fingerprints help solve the Dead Sea Scroll puzzle

Coronavirus Testing: CRISPR Technology Set to Streamline Viral Testing

If we could run back 2020 to its beginning and get a do-over, chances are pretty good that we’d do a lot of things differently. There’s a ton of blame to go around on COVID-19, but it’s safe to say that one of the biggest failures of this whole episode …read more
