Phys.org / Turning four into two: How duplicated genomes become diploid again
Genome duplication probably gave biodiversity a decisive evolutionary boost. A Chinese-German research team led by Axel Meyer from the University of Konstanz has now investigated the early phases of the process known as rediploidization. ...
Phys.org / Wildfire-driven deforestation rates in California among highest in world
California has one of the highest rates of wildfire-driven deforestation in the world, and the trend has accelerated over the past three decades, according to a study from the University of California, Davis. The study, published ...
Phys.org / DNA's physical form helps direct gyrase activity and could reshape antibiotic design
New analytical methods developed at Baylor College of Medicine and collaborating institutions have increased our understanding of how bacteria manage DNA. The methods have enabled researchers to uncover how the sequence, ...
Phys.org / Light-powered propulsion expands space exploration possibilities
Reaching the nearest star system, Alpha Centauri, would take hundreds of thousands of years using current rocket propulsion technology. Researchers in the J. Mike Walker '66 Department of Mechanical Engineering at Texas A&M ...
Phys.org / Millions of atoms, shifting bonds—new software brings living chemistry into view
Chemical reactions drive life. They ensure that cells obtain energy, proteins perform their functions, and DNA changes under certain conditions. However, many of these processes occur on extremely small scales—so small and ...
Phys.org / Quantum simulations that bypass resolution limits offer insights into high-temperature superconductivity
A new method developed at LMU overcomes fundamental resolution limits and may provide insights into high-temperature superconductivity. Physicist Dr. Sebastian Paeckel has developed a method that can be used to calculate ...
Phys.org / NASA unveils Roman telescope to map universe, find 10,000s of exoplanets
NASA unveiled a new telescope on Tuesday to scan vast swaths of the universe for planets outside our solar system and probe the mysteries of dark matter and dark energy.
Phys.org / Astronomers find an exo-Jupiter, and it seems to have clouds
A team of astronomers led by Elisabeth Matthews at the Max Planck Institute for Astronomy (MPIA) has made a discovery that highlights the limits of most current models of exoplanet atmospheres: water-ice clouds on a distant ...
Phys.org / Elusive tularemia proteins reveal possible treatment target in rare tick-borne disease
Tularemia is a rare but highly infectious disease caused by Francisella tularensis, a bacterium that can evade immune defenses. Symptoms of infection can include fever, swollen lymph nodes, and—in some cases—pneumonia. What ...
Phys.org / They promised climate action for years, but what these meat and dairy giants were really selling was something else
The meat and dairy industry accounts for 57% of total global food production emissions and at least 16.5% of all global greenhouse gas emissions. But the vast majority of environmental claims from the animal agricultural ...
Phys.org / A vast Indigenous American genome map exposes lost migrations, ancient ancestry and more than a million new variants
Research into human genomic diversity has a number of applications in biomedicine, evolution, and history. However, many populations have historically been underrepresented on the human genomic map. This is the case of Native ...
Phys.org / Chalk-stream salmon could become an official sub-species
Chalk-stream salmon should be officially classified as a sub-species, new research suggests. Scientists from the University of Exeter and INRAe (France) carried out detailed genetic testing of salmon from 42 rivers in England, ...
