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 / 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 / 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 ...
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 / A hormone can access the brain by 'hitchhiking' on extracellular vesicles, researchers discover
Researchers at Touro University Nevada have discovered that tiny particles in the blood, called extracellular vesicles (EVs), are a major player in how a group of hormones are shuttled through the body. Physical exercise ...
Phys.org / Making lighter work of calculating fluid and heat flow
Scientists from Tokyo Metropolitan University have re-engineered the popular Lattice-Boltzmann Method (LBM) for simulating the flow of fluids and heat, making it lighter and more stable than the state-of-the-art.
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 / Nanomotors drive protein network formation inside artificial cells
No one has yet created a fully functioning artificial cell. But a research team at Aarhus University has taken a step in that direction:
Phys.org / Room-temperature electron behavior defies expectations, hinting at ultra-efficient electronics
Scientists have discovered a way to efficiently transfer electrical current through specific materials at room temperature, a finding that could revolutionize superconductivity and reshape energy preservation and generation.
