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 / 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 / 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 / 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 / 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 ...
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 / 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 / Lipid nanoparticles deliver one-two punch to shrink resistant oral tumors in preclinical models
Oral squamous cell carcinoma (OSCC) is the most common form of head and neck cancer, and the number of new cases is predicted to rise by 30% in the next decade. Despite decades of cancer research, treating OSCC remains a ...
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 / Quantum internet leaves the lab with first real-world entanglement over busy telecom fiber
Quantum information is notoriously fragile. Internet traffic is anything but. Yet Northwestern University scientists have demonstrated they can peacefully coexist inside the same fiber-optic cable.
Phys.org / Kindness emerges intuitively in young children before reflection catches up, study finds
While humans are inherently social beings, psychology studies suggest that their social skills are gradually fine-tuned over time and with experience. Understanding when different social skills emerge and how they typically ...
