Phys.org / Expands the genetic alphabet: Artificial DNA base pair uses halogen bonds to form stable structures
For the first time, researchers have succeeded in developing an artificial DNA base pair that is based on a different chemical force than natural genetic material. While the common natural DNA building blocks are held together ...
Phys.org / Uncovering evolution at the center of cell division
Centromeres play virtually the same central role across the entire tree of life: They ensure the faithful segregation of chromosomes during cell division. Yet the striking diversity in centromere architecture—from large, ...
Phys.org / Stronger scents and healthier crops: Unlocking plants' hidden potential through precision gene editing
Scientists have long sought to understand why some plants are fragrant powerhouses while others remain subtle. Now, a research team from the Hebrew University of Jerusalem has cracked a genetic "bottleneck," using precision ...
Phys.org / Triplet superconductivity—physicists may have found the missing link for quantum computers
Many physicists are searching for a triplet superconductor. Indeed, we could all do with one, although we may not know it yet—or understand why. Triplet superconductors could be the key to achieving the most energy-efficient ...
Phys.org / Webb maps the mysterious upper atmosphere of Uranus
For the first time, an international team of astronomers have mapped the vertical structure of Uranus's upper atmosphere, uncovering how temperature and charged particles vary with height across the planet. Using Webb's NIRSpec ...
Phys.org / How fast is the universe expanding? Supernova could provide the answer
That the universe is expanding has been known for almost a hundred years now, but how fast? The exact rate of that expansion remains hotly debated, even challenging the standard model of cosmology. A research team at the ...
Phys.org / A key out-of-Africa site just got older: Dating methods push 'Ubeidiya site back at least 1.9 million years
A new study provides a clearer timeline for one of the most significant prehistoric sites worldwide for the study of human evolution. By integrating three advanced dating techniques, researchers have determined that the site ...
Phys.org / Storms reveal rare 2,000-year-old footprints on Scottish beach
Storms that recently ravaged Britain's coastline have revealed 2,000-year-old footprints on an Angus beach—one of only a handful of locations in the U.K. where markings of this kind have ever been discovered. The imprints ...
Phys.org / Mother-daughter bonds in red deer tied to survival and more surviving calves
Strong social networking plays an important role in human relationships. New research on female red deer shows that those bonds are also crucial for their reproductive success and survival. The study, which looked at more ...
Phys.org / A new method to decode how DNA 'switches' control gene activity
DNA is the blueprint of life. Genes encode proteins and serve as the body's basic components. However, building a functioning organism also requires precise instructions about when, where, and how much those components should ...
Phys.org / Female meiosis in plants can be directly observed with new method
A research team at the IPK Leibniz Institute has developed a method that enables the detailed observation of female meiosis—the process by which germ cells are formed—in the model plant Arabidopsis thaliana. The FeM-ID ...
Phys.org / Global study finds smaller fish and shifting food webs despite stable species numbers
Species numbers alone do not fully capture how ecosystems are changing. In a global study, scientists analyzed long-term data from nearly 15,000 marine and freshwater fish communities. They found that fish food webs have ...
