Viral genome sequencing of wastewater can detect new SARS-CoV-2 variants before they are detected by local clinical sequencing, according to a new study reported in mBio,…
New probes allow scientists to see four-stranded DNA interacting with molecules inside living human cells, unraveling its role in cellular processes. DNA usually forms the…
Some organisms evolve an internal switch that can remain hidden for generations until stress flicks it on. Computer simulations of cells evolving over tens of…
Thanks to the marine worm Platynereis dumerilii, an animal whose genes have evolved very slowly, scientists from CNRS, Université de Paris and Sorbonne Université, in…
Researchers have found a simple way to eliminate almost all sequencing errors produced by a widely used portable DNA sequencer, potentially enabling scientists working outside…
The iconic, prehistoric dire wolf, which prowled through Los Angeles and elsewhere in the Americas over 11 millennia ago, was a distinct species from the…
A new Northwestern University-led study is unfolding the mystery of how RNA molecules fold themselves to fit inside cells and perform specific functions. The findings…
International Ukraine Genetic Diversity Project finds a quarter of the genetic variation in Europe, dramatically increasing information on population diversity and medical genetic variation. Today,…
In Michelle O’Malley’s lab, a simple approach suggests a big leap forward in addressing the challenge of antibiotic-resistant bacteria. Scientists have long been aware of…
Cellular senescence, a state of permanent growth arrest, has emerged as a hallmark and fundamental driver of organismal aging. It is regulated by both genetic…
A link between evolution over short time frames (microevolution) and long time frames (macroevolution) that could open new approaches to understanding some of biology’s deepest…
Humans have them, so do other animals and plants. Now research reveals that bacteria too have internal clocks that align with the 24-hour cycle of…
University of California, San Francisco (UCSF) scientists have discovered a new way to control the immune system’s “natural killer” (NK) cells, a finding with implications…
Often considered the world’s oddest mammal, Australia’s beaver-like, duck-billed platypus exhibits an array of bizarre characteristics: it lays eggs instead of giving birth to live…
Northeastern Asia has a complex history of migrations and plague outbursts. That is the essence of an international archaeogenetic study published in Science Advances and…
Three papers unveil the extraordinary diversity of animal sex chromosomes. The sex chromosomes genetically define the developmental fate of an embryo to become a male…
