Phys.org / National food waste recycling promises major climate gains but comes with microplastic risks
Keeping food waste out of landfills provides climate and other environmental benefits, and Vermont requires residents to divert these materials to better management pathways. With other states considering similar policies, ...
Phys.org / Simple circuit brings topological insulators closer to practical electrical measurement standards
Researchers at the University of Würzburg have succeeded in detecting exceptionally robust electrical transport in a topological insulator. This could lead to new metrological applications. The work is published in the journal ...
Phys.org / Striped or checkered? Magnetic field influences competing electronic patterns in a graphene-like quantum material
In most everyday materials, such as copper, silver and silicon, the behavior of electrons is relatively predictable. In quantum materials, however, electrons can interact in complex ways, giving rise to collective electronic ...
Phys.org / Global map reveals mining's uneven toll on forests and biodiversity
A new study led by Japanese researchers from Tohoku University and the National Institute for Environmental Studies (NIES) reveals that some of the minerals most essential for green technologies may have a significant negative ...
Phys.org / Shaking atoms to bring black-hole quantum chaos into the lab
Physicists have discovered a surprisingly simple way to reproduce one of the most fascinating models in modern physics—linked to black holes, quantum chaos and exotic electronic materials—using ultracold atoms trapped in ...
Phys.org / How insect submariners survive the depths without imploding
Deep-diving insect larvae are challenging a long-held idea about why there are almost no insects in the ocean, thanks to sturdy air sacs. In Lake Malawi in East Africa, billions of lake fly larvae (Chaoborus edulis) make ...
Phys.org / Zebrafish rebuild damaged 'second brain' networks in nine days, offering clues for nerve repair
Why can zebrafish regenerate damaged gut nerves while humans largely cannot? Michigan State University researchers have developed a new research tool that allows them to remove gut neurons in zebrafish and watch them regenerate ...
Phys.org / Peptide isolated from a Cerrado frog increases strawberry shelf life
Five minutes. That was the amount of time that Oso Grande strawberries remained in contact with the Ctx(Ile21)-Ha peptide—a molecule isolated from a frog native to the Brazilian Cerrado—in experiments conducted in Brazil ...
Phys.org / Nanopores can activate human T cells without biochemical signals
Immune cells protect and heal the human body. In medicine, they are specifically activated through biochemical reactions to treat certain diseases. Researchers at the Helmholtz-Zentrum Hereon, ETH Zurich, Humboldt University ...
Phys.org / New physics-based metric improves estimates of climate-driven cooling demand
New research led by atmospheric scientists at the University of Hawai'i (UH) at Mānoa found that the century-old yardstick used across many industries to estimate air-conditioning and refrigeration energy demand—called cooling ...
Phys.org / Yeast survives after all 300 known spliceosomal introns are removed
Spliceosomal introns are noncoding DNA sequences located between exons in many eukaryotic protein-coding genes. Most are removed post-transcriptionally by RNA splicing and do not encode proteins, but they have been implicated ...
Phys.org / Silkworm cultivation predates the Silk Road in southern Central Asia, ancient cocoons suggest
The silkworm moth, whose caterpillars have been used in silk production since antiquity, may have been brought to southern Central Asia 4,000 years ago—nearly 2,000 years earlier than previously assumed—according to new research ...
