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 / 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 / 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 / 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 / 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 / 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 / Programmable platform enables on-demand design of plant immune receptors against crop pathogens
Crop production faces threats from plant pathogens. Traditional disease-resistance breeding relies heavily on natural plant resistance genes that encode immune receptors adapted to particular pathogens. However, rapidly evolving ...
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 ...
Phys.org / Heat is coming for Hawaiian corals, but study finds there may be time to adapt
Since the first major bleaching event in 1996, Hawaiian corals have been subject to increasing heat stress and more frequent bleaching events. New research from oceanographers at the University of Hawai'i at Mānoa used high-resolution ...
Phys.org / First 3D nanoscale maps of human airway epithelium reveal hidden architecture of lung defense cells
Researchers at Queen Mary University of London and University of Cambridge in collaboration with colleagues at HHMI Janelia and NIH, have created some of the most detailed three-dimensional maps ever generated of human airway ...
Phys.org / Virtual café experiment finds Japanese participants keep greater distance than Italians
How close do we stand to other people during a social interaction? The distance we maintain between our body and that of another person—known as interpersonal distance—is a fundamental aspect of everyday life. It influences ...
Phys.org / Ceramic vessels reveal how social inequalities were also cooked into 19th-century Brazil
Fish, shellfish, maize, manioc, rice and even chicken eggs. Molecular residues preserved in more than 180 ceramic vessels from southern Brazil have made it possible to reconstruct what different communities were cooking more ...
