Phys.org / DNA transcription is a tightly choreographed event: How RNA polymerase II regulates the dance
Life's instructions are written in DNA, but it is the enzyme RNA polymerase II (Pol II) that reads the script, transcribing RNA in eukaryotic cells and eventually giving rise to proteins. Scientists know that Pol II must ...
Phys.org / Drones: An ally in the sky to help save elephants
They say an elephant never forgets—and it turns out they can learn to adapt to drones. Once seen as a source of alarm, drones are now proving to be surprisingly elephant-friendly and a valuable research tool. Previously, ...
Phys.org / Earth system models overstate carbon removal: New findings suggest nitrogen fixation is 50% lower than thought
High levels of atmospheric carbon dioxide intensify climate change, but high carbon dioxide levels can also stimulate plant growth. Plant growth removes carbon dioxide from the atmosphere, partially mitigating the effects ...
Phys.org / Meteorite samples are time capsules from the early solar system
When a meteor streaks across the sky, it's not just beautiful. It's nature's way of delivering a time capsule to Earth. Contained within are hints about the very beginning of the solar system and how planets, including our ...
Phys.org / Watching metal crystals grow inside liquid metal: Imaging technique could boost hydrogen production
If you dissolve sugar in hot water and then cool it down, you'll see pure sugar crystals form while impurities stay in the liquid. You can even watch the beautiful sugar crystals slowly grow in the water.
Phys.org / RNA in action: Filming ribozyme self-assembly
RNA is a central biological macromolecule, now widely harnessed in medicine and nanotechnology. Like proteins, RNA function often depends on its precise three-dimensional structure. A recent study published in Nature Communications ...
Phys.org / Scientists capture the crackling sounds of what they believe is lightning on Mars
Scientists have detected what they believe to be lightning on Mars by eavesdropping on the whirling wind recorded by NASA's Perseverance rover.
Phys.org / Social media research tool can lower political temperature—it could also lead to more user control over algorithms
A new tool shows it is possible to turn down the partisan rancor in an X feed—without removing political posts and without the direct cooperation of the platform.
Phys.org / New study shows how DNA is recognized by proteins that control gene expression
With a new study in the journal Cell, researchers at Stanford University and Stockholm University have contributed to increased knowledge about gene regulation in human cells.
Phys.org / Telescope in Chile captures stunning new picture of a cosmic butterfly
A telescope in Chile has captured a stunning new picture of a grand and graceful cosmic butterfly.
Medical Xpress / Largest analysis confirms medication and CBT as top ADHD treatment options
The most comprehensive review to date of ADHD treatments has found that medication for children and adults, and cognitive behavioral therapy for adults, remain the most effective approaches, backed by the strongest short-term ...
Phys.org / Mystery foot belongs to ancient human relative: Scientists
Newly discovered fossils prove that a mysterious foot found in Ethiopia belongs to a little-known, recently named ancient human relative who lived alongside the species of the famous Lucy, scientists said Wednesday.
