Phys.org / Environmental bacteria ferry genes that boost antibiotic resistance over 10,000-fold
A patient with a severe infection is prescribed a potent antibiotic. Hopes for improvement are high, but just after treatment is given, resistance to the drug increases thousands of times. How could this happen?
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 / 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 / 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 / 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 / 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 / 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 / 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 / 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 / Training microbes to prepare soils for the impacts of climate change
Scientists at the University of Lincoln have discovered a promising new way to help protect crops from one of climate change's growing threats to global food production—increasing soil salinity.
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, ...
