Phys.org / Virus-like particles enable gene activity tracking over time in the same cells
In recent years, scientists have developed methods to measure a cell's transcriptome, or all the RNA produced by a cell, to study the cell's identity and genetic activity. However, these methods rely on killing the cell to ...
Phys.org / Ultrafast electrons and lasers reveal unexpectedly strong radiation signals in common semiconductors
Detecting radiation is key to technologies ranging from particle accelerators and scientific instruments to medical imaging and security screening. But current detectors must often make trade-offs, providing signals that ...
Phys.org / Rescue satellite gets close to NASA's doomed telescope, even if it can't save it
A private spacecraft that was supposed to provide a lifeline to NASA's Swift Observatory managed to get close to the sinking telescope and even snap photos two weeks after the rescue was abandoned.
Phys.org / Researchers tune into Arctic under-ice sounds and test through-ice communication
Beneath the Arctic Ocean is an orchestra featuring natural and human composers, from cracking sea ice and whistling beluga whales to humming shipping-vessel engines. Researchers from MIT Lincoln Laboratory heard some of this ...
Phys.org / New AI tool maps the hidden universe of small molecules
The human body and its gut microbiome produce thousands of small molecules that shape how the body functions—influencing immunity, metabolism and more. Identifying what those molecules actually are has been one of the biomedical ...
Phys.org / In ant nervous systems, gene expression may drive rescue behavior
Why do some ants help nestmates in distress while others don't? A research team from Johannes Gutenberg University Mainz (JGU) and Tel Aviv University addressed this question in a new study. The researchers examined worker ...
Phys.org / Archaea as 'flexitarians': Ammonia-oxidizing microbes also feed on amino acids
Symbiotic ammonia-oxidizing archaea in marine sponges are not strict specialists but true "flexitarians." A team led by microbiologists Bettina Glasl and Katharina Kitzinger from the University of Vienna, in collaboration ...
Phys.org / AI-driven polymer discovery could replace years of trial and error with closed-loop testing
In the realm of materials science, there is a plethora of datasets and tools at our disposal—the issue is how to effectively use these resources in harmony. Researchers at the Advanced Institute for Materials Research (WPI-AIMR), ...
Phys.org / Davyne changes color beyond human sight, opening path to invisible security tags
While studying the properties of hackmanite, researchers created a new material called davyne that changes color in the near-infrared region. The color change cannot be detected with the human eye, but only with a spectrometer ...
Phys.org / Molecular snapshots reveal how bacteria assemble outer membrane proteins
Gram-negative bacteria are responsible for several infections that are hard to treat because of their high resistance to antibiotics. These bacteria possess an outermost layer called the outer membrane that acts as a protective ...
Phys.org / Embedded platinum channels bring nanoscale spin-based thermoelectric conversion to bulk materials
A joint research team from NIMS and the University of Tokyo has developed a new composite in which three-dimensional nano-interfaces are distributed throughout the material by coating the surfaces of magnetic-insulator powders ...
Phys.org / 'Hidden order in disorder' makes nanodevices easier to design
Augmented reality (AR) glasses, lenses thinner than a human hair, and holograms floating above your fingertips may sound like technologies from science fiction. At the heart of these emerging technologies, however, lies a ...
