Phys.org / Ancient mammoth remains yield the world's oldest host-associated bacterial DNA
An international team led by researchers at the Center for Paleogenetics, has uncovered microbial DNA preserved in woolly and steppe mammoth remains dating back more than one million years. The analyses reveal some of the ...
Phys.org / 8,000 years of human activities have caused wild animals to shrink and domestic animals to grow
Humans have caused wild animals to shrink and domestic animals to grow, according to a new study out of the University of Montpellier in southern France. Researchers studied tens of thousands of animal bones from Mediterranean ...
Phys.org / TESS reveals two rocky Earth-sized exoplanets orbiting nearby K-type star
Using NASA's Transiting Exoplanet Survey Satellite (TESS), astronomers have discovered two rocky exoplanets orbiting a nearby K-type star, known as TOI-2322. The newfound alien worlds are comparable in size to Earth and have ...
Phys.org / Direct plasma membrane-to-ER lipid transfer outpaces vesicular trafficking, study reveals
Max Planck Institute of Molecular Cell Biology and Genetics led a study showing that directional, non-vesicular lipid transport drives fast, species-selective lipid sorting, outpacing slower, less specific vesicular trafficking, ...
Phys.org / Traces of blue indigo on 34,000-year-old grinding tools suggest new Paleolithic plant use scenarios
An international research team coordinated by Ca' Foscari University of Venice has identified the presence of indigotin—a blue dye compound—on stone pebbles dating back to the Upper Paleolithic. This molecule, derived ...
Phys.org / New catalyst could make mixed plastic recycling a reality
The future of plastic recycling may soon get much less complicated, frustrating and tedious. In a new study, Northwestern University chemists have introduced a new plastic upcycling process that can drastically reduce—or ...
Phys.org / Quantum researchers observe real-time switching of magnet in heart of single atom
Researchers from Delft University of Technology in the Netherlands have been able to see the magnetic nucleus of an atom switch back and forth in real time. They read out the nuclear "spin" via the electrons in the same atom ...
Phys.org / Once king of the seas, a giant iceberg is finally breaking up
Nearly 40 years after breaking off Antarctica, a colossal iceberg ranked among the oldest and largest ever recorded is finally crumbling apart in warmer waters, and could disappear within weeks.
Phys.org / Magnetic fields in infant universe may have been billions of times weaker than a fridge magnet
The magnetic fields that formed in the very early stages of the universe may have been billions of times weaker than a small fridge magnet, with strengths comparable to magnetism generated by neurons in the human brain. Yet, ...
Phys.org / Investigating an island of inversion: Physicists pinpoint boundary where nuclear shell model breaks down
An experiment carried out at CERN's ISOLDE facility has determined the western shore of a small island of atomic nuclei, where conventional nuclear rules break down.
Phys.org / Cellophane bees are built for chill temperatures, more so than honeybees
The cellophane bee might be the ultimate spring breaker. A solitary bee that nests in the ground, it's one of the very first pollinators to emerge every year—often before the snowmelt.
Phys.org / Explaining a quantum oddity with five atoms
Matter gets weird at the quantum scale, and among the oddities is the Efimov effect, a state in which the attractive forces between three or more atoms bind them together, even as they are excited to higher energy levels, ...
