Phys.org / New model links carbon-13 spike to Great Oxidation Event 2.45 billion years ago
Two University of Victoria (UVic) geologists have integrated field geology with statistical modeling to give scientists a new view of the chemical reactions happening on ocean floors billions of years ago. The revised picture ...
Phys.org / Opening a new window into superconductivity by reimagining a classic tool
For more than a century, condensed matter physics has grappled with one of its greatest unsolved challenges: how to build superconductors that operate at room temperature and transmit electricity with no loss. Now, in a paper ...
Phys.org / Why some regions are winning the fight against groundwater depletion
For half the world's population, the water in their drinking glasses comes from below them. Groundwater also supplies 40% of global irrigation projects. Alarmingly, more than a third of the planet's aquifers, or groundwater ...
Phys.org / Synthesis of amino acids from carbon reaches 97% efficiency with cell-free system
The building blocks of proteins, amino acids, are essential for all living things. Twenty different amino acids build the thousands of proteins that carry out biological tasks. While some are made naturally in our bodies, ...
Phys.org / ALICE sees new sign of primordial plasma in proton collisions
The ALICE Collaboration takes a step further in addressing the question of whether a quark–gluon plasma can be formed in proton–proton and proton–nucleus collisions. In the first few microseconds after the Big Bang, ...
Phys.org / New controls can stretch, blur and even reverse quantum time flow
In new research published in Physical Review X, scientists have designed quantum control protocols that generate processes more consistent with time flowing backward than forward. The protocols—techniques to control quantum ...
Phys.org / Designing better 2D electronics: Addressing anisotropic conductivity to cut contact resistance
The high-performance semiconductor devices powering smartphone displays, AI computing, EV batteries and more are increasingly incorporating 2D materials to overcome silicon's scaling limits. To optimize these technologies, ...
Phys.org / Reconstructing food webs to reveal a dynamic Gulf of Maine
When most people think about corals, they imagine a tropical reef with crystal blue water, teeming with colorful fish. But, in the depths of the cold, murky Gulf of Maine, deep-sea corals thrive, feasting on a steady supply ...
Phys.org / Researchers uncover gut-liver serotonin pathway that limits nanoparticle and viral delivery
A new study has for the first time elucidated the gut-liver immune regulatory axis jointly maintained by intestinal commensal bacteria and the intestinal endocrine system, and uncovered the fundamental mechanism underlying ...
Phys.org / A self-sufficient Mars garden? How cyanobacteria-based fertilizer could grow edible biomass
A research team from the Center for Applied Space Technology and Microgravity (ZARM), the Department of Environmental Process Engineering (UVT) at the University of Bremen and the German Aerospace Center (DLR) has made significant ...
Phys.org / Impressionist sea slugs create their patterns by arranging colorful photonic crystals
Nudibranchs are often referred to as the butterflies of the sea. Nudibranchs live worldwide, primarily in warm, shallow marine regions, and stand out for their flamboyant colors and diverse shapes. A team from the Max Planck ...
Phys.org / Moss-associated nitrogen fixation helps sustain plant growth in warming permafrost ecosystems
Climate warming can increase plant growth in permafrost regions by lengthening the growing season, speeding up plant metabolic processes, and allowing deeper root penetration as permafrost thaws. However, the capacity for ...
