An article published in the Journal of Controlled Release details the results of a cross-border scientific collaboration that has developed an alternative for the treatment of solid tumors based on inhibition of the inflammatory tumor microenvironment (TME). Solid tumors are difficult to treat, partly owing to cells and substances in the TME that prevent drugs from penetrating and stop the patient's own immune system from combating the tumor. "These cells and molecules often fuel [...]

Imaging the hot turbulence of aircraft propulsion systems may now be possible with sturdy sheets of composite materials that twist light beams, according to research led by the University of Michigan and Air Force Research Laboratory. The sheets were produced with a new manufacturing method that opens possibilities beyond aircraft design, as it enables new classes of materials to be used in polarization optics. While the team demonstrated high temperature tolerance, new mechanical, [...]

Researchers at the University of São Paulo (USP) in Brazil have developed a bioelectronic chip that simultaneously detects vitamins C and D in body fluids. It is flexible and easy to use, and can be adapted for use in a wearable device to assist with a personalized diet. Details are described in an article published in ACS Applied Nano Materials, and featured on the cover of the journal. Vitamins C and D are micronutrients that play a vital role in the immune system as participants in [...]

A nanoemulsion containing particles of curcumin, which is known to have anti-inflammatory and antioxidant properties, was found capable of modulating the gut microbiota of mice with intestinal inflammation in experiments conducted by researchers at the University of Western São Paulo (UNOESTE) and São Paulo State University (UNESP) in Brazil. The study was supported by FAPESP (projects 22/12823-0, 20/15185-0 and 17/03879-4), and is reported in an article [...]

Entanglement is a property of quantum physics that is manifested when two or more systems interact in such a way that their quantum states cannot be described independently. In the terminology of quantum physics, they are said to be entangled, i.e. strongly correlated. Entanglement is of paramount importance to quantum computing. The greater the entanglement, the more optimized and efficient the quantum computer. A study conducted by researchers affiliated with the Department of Physics at [...]

A low-cost technology involving nanoparticles loaded with antibiotics and other antimicrobial compounds that can be used in multiple attacks on infections by the bacterium responsible for most cases of tuberculosis has been developed by researchers at São Paulo State University (UNESP) in Brazil and is reported in an article published in the journal Carbohydrate Polymers. Results of in vitro tests suggest it could be the basis for a treatment strategy to combat multidrug bacterial [...]

Summary: A nitrogen-vacancy (NV) center is a flaw in the diamond crystal structure that occurs when an adjacent lattice site becomes unoccupied and a nitrogen atom takes the place of a carbon atom. Researchers are interested in color centers, which are fluorescent imperfections in diamonds that emit single photons at ambient temperature and with a long coherence time due to their quantum characteristics.

A nitrogen-vacancy (NV) center is a defect in the crystal structure of diamond, where a nitrogen atom replaces a carbon atom in the diamond lattice and a neighboring site in the lattice is vacant. This and other fluorescent defects in diamond, known as color centers, have attracted researchers’ attention owing to their quantum properties, such as single-photon emission at room temperature and with long coherence time. Their many applications include quantum information encoding and [...]
