45,000-year-old human genomes reveal extent of Neanderthal interbreeding

Two new genetic studies have shed light on just how often our ancestors got frisky with Neanderthals. Scientists analyzed the genomes of 45,000-year-old human remains found in caves in Czechia and Bulgaria, including the oldest known genome of a modern… Continue reading 45,000-year-old human genomes reveal extent of Neanderthal interbreeding

New insights into how night shift work heightens cancer risk

Compelling new experimental research has found circadian rhythm disruptions caused by night shift work can alter the expression of tumor-related genes, making one more vulnerable to the DNA damage that leads to cancer. The study builds on a growing und… Continue reading New insights into how night shift work heightens cancer risk

Synthetic molecule delivers more robust DNA data storage

A team of researchers led by professor of pharmaceutical sciences John Chaputa at the University of California, Irvine (UCI) is developing methods for storing vast amounts of data on strands of synthetic DNA that are much tougher than natural DNA. The … Continue reading Synthetic molecule delivers more robust DNA data storage

Million-year-old mammoth DNA smashes record for world’s oldest

A new DNA discovery reveals a previously unknown lineage of mammoth

A new study published in the journal Nature is describing the extraction and sequencing of the oldest known sample of DNA. The sample comes from an ancient species of mammoth found in the Siberian permafrost and dates back nearly 1.2 million years.

“Living fossil” genome sequence reveals clues to evolution of life on land

Genome sequencing can teach us a huge amount about a species, and now scientists have completed the sequence for one of the weirdest and most intriguing animals in the world. The Australian lungfish is a “living fossil” from the time our ancestors firs… Continue reading “Living fossil” genome sequence reveals clues to evolution of life on land

Designer DNA molecule helps hunt down cancer stem cells in blood

Like weeds that grow back if you don’t remove the roots, cancer can keep returning thanks to lurking stem cells. Now, researchers have developed a “designer” DNA segment that can eradicate these cancer stem cells, with tests in mice showing promising e… Continue reading Designer DNA molecule helps hunt down cancer stem cells in blood
