Phys.org / Mysterious, thermally insulating patches at the base of Earth's mantle
With modern seismic tomography, Earth scientists have discovered that above Earth's core-mantle boundary (CMB), about 2,900 kilometers beneath our feet, there is a thin layer about 300 kilometers thick with remarkable structural ...
Phys.org / Rare Hall effect reveals design pathways for advanced spintronic materials
Scientists at Ames National Laboratory, in collaboration with Indranil Das's group at the Saha Institute of Nuclear Physics (India), have found a surprising electronic feature in transitional metal-based compounds that could ...
Phys.org / Why a chiral magnet is a direction-dependent street for electrons
RIKEN physicists have discovered for the first time why the magnitude of the electron flow depends on direction in a special kind of magnet. This finding could help to realize future low-energy devices.
Phys.org / New tool predicts road expansion, deforestation and disease hotspots
Researchers have developed a tool that reliably predicts where destructive new roads are likely to carve through tropical forests, giving environmentalists and public health officials a head-start in identifying at-risk areas ...
Phys.org / Robotic system synthesizes hundreds of metal complexes to find potential new antibiotic
Researchers have used a cutting-edge robotic system capable of synthesizing hundreds of metal complexes to develop a possible antibiotic candidate—offering fresh hope in the global fight against drug-resistant infections.
Phys.org / Passive adaptation mechanism reveals how cells balance their protein levels
Every cell depends on proteins to function and stay healthy. These proteins are made inside the cell from amino acids, but cannot simply accumulate inside the cell forever. Once they have done their job or become damaged, ...
Phys.org / A third path to explain consciousness: Biological computationalism
Right now, the debate about consciousness often feels frozen between two entrenched positions. On one side sits computational functionalism, which treats cognition as something you can fully explain in terms of abstract information ...
Phys.org / Anything-goes 'anyons' may be at the root of surprising quantum experiments
In the past year, two separate experiments in two different materials captured the same confounding scenario: the coexistence of superconductivity and magnetism. Scientists had assumed that these two quantum states are mutually ...
Phys.org / Scientists chart over 140,000 DNA loops to map human chromosomes in the nucleus
One of the most detailed 3D maps of how the human chromosomes are organized and folded within a cell's nucleus is published in Nature.
Phys.org / Two ancient human species came out of Africa together, not one, suggests new study
The textbook version of the "Out of Africa" hypothesis holds that the first human species to leave the continent around 1.8 million years ago was Homo erectus. But in recent years, a debate has emerged suggesting it wasn't ...
Phys.org / The simulation hypothesis: Mathematical framework redefines what it means for one universe to simulate another
The simulation hypothesis—the idea that our universe might be an artificial construct running on some advanced alien computer—has long captured the public imagination. Yet most arguments about it rest on intuition rather ...
Phys.org / Kolmogorov-Arnold networks bridge AI and scientific discovery by increasing interpretability
AI has successfully been applied in many areas of science, advancing technologies like weather prediction and protein folding. However, there have been limitations for the world of scientific discovery involving more curiosity-driven ...
