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 / 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 / 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 / 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 / CT scans help detect ancient earthquakes in Hamilton Basin
In a world-first use of medical imaging technology, scientists have revealed the earthquake-generating potential of faults in the Hamilton and Hauraki areas. The study shows that hidden geological faults in Hamilton city ...
Phys.org / The Princess of Bagicz: Dendrochronology settles debate over age of rare Roman-era wooden coffin
Dr. Marta Chmiel-Chrzanowska and her colleagues conducted a multidisciplinary analysis of the only known preserved wooden coffin from the Roman Iron Age, the Princess of Bagicz. The study, published in Archaeometry, used ...
Phys.org / Chitosan-nickel biomaterial becomes stronger when wet, and could replace plastics
A new study led by the Institute for Bioengineering of Catalonia (IBEC) has unveiled the first biomaterial that is not only waterproof but actually becomes stronger in contact with water. The material is produced by the incorporation ...
Phys.org / Giant DNA viruses encode their own eukaryote-like translation machinery, researchers discover
In a new study, published in Cell, researchers describe a newfound mechanism for creating proteins in a giant DNA virus, comparable to a mechanism in eukaryotic cells. The finding challenges the dogma that viruses lack protein ...
Phys.org / Measuring chaos: Researchers quantify the quantum butterfly effect
For the first time, researchers in China have accurately quantified how chaos increases in a quantum many-body system as it evolves over time. Combining experiments and theory, a team led by Yu-Chen Li at the University of ...
Phys.org / Ultra-stable lasers that rely on crystalline mirrors could advance next-generation clocks and navigation
Lasers, devices that emit intense beams of coherent light in specific directions, are widely used in research settings and are central components of various technologies, including optical clocks (i.e., systems that can keep ...
Phys.org / A super stable laser on the moon could guide future lunar missions and improve our timekeeping
Scientists are proposing to build a laser in a crater on the moon to help future lunar missions land safely in the dark and find their way around. This ultra-stable light source could also help us keep time more accurately, ...
Phys.org / Araish spiral galaxy observations uncover a 26,700-light-year radio jet
An international team of astronomers has performed multi-wavelength observations of the nearby Araish galaxy to investigate the origin of its radio emission. As a result, they detected an extended radio jet of this galaxy. ...
