Phys.org / NASA fuels its moon rocket in a crucial test to decide when Artemis astronauts will launch
NASA fueled its new moon rocket in one final make-or-break test Monday, with hopes of sending astronauts on a lunar fly-around as soon as this coming weekend.
Phys.org / Reshaping gold leads to new electronic and optical properties
By changing the physical structure of gold at the nanoscale, researchers can drastically change how the material interacts with light—and, as a result, its electronic and optical properties. This is shown by a study from ...
Phys.org / Some tropical land may heat up nearly twice as much as oceans under climate change, sediment record suggests
Some tropical land regions may warm more dramatically than previously predicted, as climate change progresses, according to a new CU Boulder study that looks millions of years into Earth's past. Using lake sediments from ...
Phys.org / New database reveals how Americans use water
Water powers our lives. It feeds our crops, keeps factories running, generates electricity, and fills our taps. But until now, no one had a clear, national picture of how much water we're using—and for what.
Phys.org / Analyzing an enigmatic enzyme with potential for new antibiotic drug discovery
An analysis of an unusual enzyme could result in a new generation of antimicrobial medicines to counter antibiotic resistance. Key details in the enzyme-driven biosynthesis of a natural molecule with potent antibiotic activity ...
Dialog / Infrared running of gravity offers a field-theoretic route to dark matter phenomena
The mystery of dark matter—unseen, pervasive, and essential in standard cosmology—has loomed over physics for decades. In new research, I explore a different possibility: Rather than postulating new particles, I propose ...
Phys.org / Mapping how Arctic groundwater will respond to thawing permafrost
Dalhousie researchers have revealed how Arctic aquifers—permeable layers of the ground that store and transmit water to rivers, lakes and terrestrial ecosystems—behave today and how these vital resources will change with ...
Phys.org / Natural magnetic materials can control light in unprecedented ways
Imagine shining a flashlight into a material and watching the light bend backward—or in an entirely unexpected direction—as if defying the law of physics. This phenomenon, known as negative refraction, could transform ...
Phys.org / A clearer look at critical materials, thanks to refrigerator magnets
With an advanced technology known as angle-resolved photoemission spectroscopy (ARPES), scientists are able to map out a material's electron energy-momentum relationship, which encodes the material's electrical, optical, ...
Phys.org / Nanotubes with lids mimic real biology
When water and ions move together through channels only a nanometer wide, they behave in unusual ways. In these tight spaces, water molecules line up in single file. This forces ions to shed some of the water molecules that ...
Phys.org / Tibet's tectonic clash: New satellite view suggests weaker fault lines
A study on tectonic plates that converge on the Tibetan Plateau has shown that Earth's fault lines are far weaker and the continents are less rigid than scientists previously thought. This finding is based on ground-monitoring ...
Phys.org / Perseverance rover completes first AI-planned drive on Mars
NASA's Perseverance Mars rover has completed the first drives on another world that were planned by artificial intelligence. Executed on Dec. 8 and 10, and led by the agency's Jet Propulsion Laboratory in Southern California, ...
