Phys.org / Thank the JWST for confirming the first runaway supermassive black hole
What could force a supermassive black hole (SMBH) out of its host galaxy? They can have hundreds of millions, even billions of solar masses. What's powerful enough to dislodge one of these behemoths?
Dialog / The moon-forming event: Why it was by explosive ejection rather than a giant impact
One of the oldest unsolved riddles in planetary science concerns the origin of the moon. Over a century ago, George Darwin proposed that tidal and centrifugal forces on a rapidly rotating proto-Earth caused the moon to be ...
Phys.org / Scientists develop a smarter mRNA therapy that knows which cells to target
Researchers at the Icahn School of Medicine at Mount Sinai have developed a first-of-its-kind mRNA system that switches on therapeutic genes preferentially inside targeted cells—an advance demonstrated in studies in mice ...
Phys.org / Ancient genetic 'start' signal found in bacteria, archaea and eukaryotes
A newly discovered promoter element "start" points to a shared regulatory syntax for controlling transcription initiation in bacteria, archaea, and eukaryotes.
Phys.org / Synthetic key enzyme enables the conversion of CO₂ into formic acid
For a carbon-neutral bioeconomy, processes are needed that can efficiently capture CO2 and convert it into valuable products. Formic acid, or more specifically its salt, formate, is considered a promising candidate as it ...
Phys.org / Dark matter search narrows as detector sets new limits and spots solar neutrinos
Australian researchers have played a central role in a landmark result from the LUX-ZEPLIN (LZ) experiment in South Dakota—the world's most sensitive dark matter detector. Today, scientists working on the experiment report ...
Phys.org / From cages to fields: Lab mice lose their anxiety after a week outdoors
When postdoctoral researcher Matthew Zipple releases lab mice into a large, enclosed field just off Cornell's campus, something remarkable happens.
Phys.org / Heavy is the head that wears the crown: Dominant baboons miss out on restful nights
Dominant baboons rule the troops by day, but at night, they may pay a hidden cost. A study led by Swansea University has found that higher-ranking baboons get less and more fragmented rest at night than their lower-ranked ...
Phys.org / NASA's Roman telescope will observe thousands of newfound cosmic voids
Our universe is filled with galaxies, in all directions as far as our instruments can see. Some researchers estimate that there are as many as 2 trillion galaxies in the observable universe. At first glance, these galaxies ...
Phys.org / Integrative quantum chemistry method unlocks secrets of advanced materials
A new computational approach developed at the University of Chicago promises to shed light on some of the world's most puzzling materials—from high-temperature superconductors to solar cell semiconductors—by uniting two ...
Phys.org / Deep-learning model predicts how fruit flies form, cell by cell
During early development, tissues and organs begin to bloom through the shifting, splitting, and growing of many thousands of cells.
Phys.org / Iconic 'Little Foot' fossil may be new type of human ancestor
An international study led by researchers from Australia's La Trobe University and the University of Cambridge has challenged the classification of one of the world's most complete human ancestral fossils, raising the possibility ...
