Phys.org / A DNA assembly kit to unlock the CRISPR-Cas9 potential for metabolic engineering
The clustered regularly interspaced short palindrome repeats (CRISPR) and Crispr-associated protein 9 (CRISPR/Cas9) is now a well-known, revolutionary method to engineer microbial cells.
Phys.org / Bioactive near-infrared II clusters for 3D imaging and acute inflammation inhibition
The bioactivity of most near-infrared II (NIRII) fluorophores are limited, thereby conflicting the achievement of strong fluorescence and high catalytic activities, due to a lack of free electrons in the method.
Medical Xpress / Study shows adipose tissue co-regulates cognitive function
In mice, cognitive decline is influenced by obesity due to the potential association of an adipose-brain axis. To examine this proposal, Núria Olivera-Canellas, and a team of researchers in the departments of medicine and ...
Phys.org / Hydrogel locomotion regulated by light and electric fields
Materials scientists aim to develop autonomous materials that function beyond stimulus responsive actuation. In a new report in Science Advances, Yang Yang and a research team in the Center for Bioinspired Energy Science ...
Medical Xpress / Electrical detection of RNA cancer biomarkers at the single-molecule level
Early screening methods offer a promising avenue to reduce mortality rates of cancer, notably through the analysis of biomarkers in liquid biopsies. Biologists have shown how the electrical detection of nucleic acids at the ...
Phys.org / Uncovering the local atomic structure of zeolite using optimum bright-field scanning transmission electron microscopy
Zeolites have unique porous atomic structures and are useful as catalysts, ion exchangers and molecular sieves. It is difficult to directly observe the local atomic structures of the material via electron microscopy due to ...
Phys.org / Isothermal self-assembly of multicomponent and evolutive DNA nanostructures
Multiple complementary DNA strands can be thermally annealed into desired entities to engineer DNA nanostructures. In a new study now published in Nature Nanotechnology, Caroline Rossi-Gendron and a team of researchers in ...
Medical Xpress / Single-dose injectable nanovaccine-in-hydrogel for robust cancer immunotherapy
The present variants of cancer immunotherapy such as immune checkpoint blockades only benefit a small subset of patients due to its immunosuppressive tumor microenvironment. The capacity to vaccinate tumors and reduce immunosuppression ...
Phys.org / Telecom-band-integrated multimode photonic quantum-memory
Quantum memory that depends on quantum-band integration is a key building block used to develop quantum networks that are compatible with fiber communication infrastructures. Quantum engineers and IT specialists have yet ...
Tech Xplore / Pressure-driven distillation for fast and selective water purification
Membrane technologies can provide efficient purification of unclear water sources to address a growing water shortage. However, when engineers develop state-of-the-art membranes, they are constrained by a lack of selectivity ...
Phys.org / Magnetic Quincke rollers: Forces and torques of magnetism that guide complex dynamics of active particles
Quincke rotation is defined as the spontaneous steady rotation of a dielectric particle immersed in a dielectric solvent under a steady and uniform electric field. Electro-hydrodynamically driven active particles based on ...
Phys.org / Dynamics of molecular rotors in bulk superfluid helium
Molecules immersed in liquid helium can probe superfluidity since their electronic, vibrational and rotational dynamics can provide valuable cues about the superfluid at the nanoscale. In a new report in Science Advances, ...
Phys.org / Laser squared: A two-domain photon-phonon laser
Lasers are a significant historical invention with ubiquitous impact in society. The concept also has interdisciplinary applications as phonon lasers and atom lasers. A laser in one physical domain can be pumped by energy ...
Phys.org / Developing a human malaria-on-a-chip disease model
In a new report published on Scientific Reports, Michael J. Rupar, and a research team at Hesperos Inc., Florida, U.S., developed a functional, multi-organ, serum-free system to culture P. falciparum—a protozoan that predominantly ...
Medical Xpress / Platinum chemotherapeutics: A sonoactivated platinum anticancer prodrug
While photoactivated chemotherapy has received significant attention, the capacity to eradicate a deep tumor by using an external source that provides high penetration depth of tissue remains challenging. In a new report ...
