Nanoparticle cell interface enables electromagnetic wireless programming of mammalian transgene expression
Nanoparticles consist of a multifaceted core (cobalt and bismuth ferrite that reacts to magnetic fields) and an outer chitosan layer (rich of positive amino groups for nanoparticles to migrate into the cytoplasm, protecting the biological environment from the nanothyroid). Credit: Lin et al. Recent technological advances have driven the development of cutting-edge technologies that can monitor and control physiological processes…

Low viscosity oil enhances microfluidic devices, allowing for safer cell research and gradient generation
This graph shows the maximum pneumatic pressure (KPA burst pressure) that a PDMS slip chip device can withstand. The device was cured at various temperatures (50°C to 120°C) and lubricated with 120 MPa.S silicone oil. This test shows that cure temperature (for example, 50°C) results in significantly higher sealing strength using rhodamine solutions. Credit: Toyohashi Institute of Technology Researchers from…

How “jump genes” penetrate DNA during cell division
ORF1P-RNP formation and DNA recognition model. ORF1P forms higher-order oligomers with HOMO trimers that can bind to DNA but may clearly prefer RNA. Credit: Sarah Zernia et al Viruses are known to use genetic machines of invading human cells to make copies of themselves. As part of the process, the virus leaves debris throughout the human genetic material (genome). Viral-like…

How influenza virus hijacks cell machines to suppress immune alarm signals
Credit: Nucleic Acid Research (2025). doi:10.1093/nar/gkaf268 Researchers at the University of Gothenburg said influenza viruses manipulate the body’s gene regulatory systems to accelerate its own spread. Their research also shows that already approved drugs may help to enhance immune defenses, but their effectiveness in humans has not yet been confirmed. Published in the journal Nucleic Acids Research, the study concerns…

Biomolecule “Silly Putty”: High-resolution imaging of cell condensates achieved using fluorogen technology
NB and NR bind to nanoscale clusters within the condensate. Credit: Nature Physics (2025). doi:10.1038/s41567-025-02827-7 Biomolecular condensates shift the masses of cells that organize cellular material. They are distinct molecular communities made up of DNA, RNA and proteins that “condensate” molecules in critical places, but often go against explanation. Partly because this is so small that it cannot be measured…

New biometric material for regenerative medicine: Scientists develop living hydrogel with cell nanocon positive
A new biological material developed by an engineer in Pennsylvania imitates an extracellular matrix, an important component of human tissue. The extracellular matrix acts like a scaffold so that the cells can be cured after damage. Credit: SHEIKHI RESEARCH GROUP/PENN State. Unauthorized reproduction is prohibited. According to Pennsylvania researchers, biological materials that can imitate specific actions in biological tissues may…
