Researchers create virus-resistant, safely restrained E. coli for medical, industrial applications
20.3.2023 | Press monitoring
In a step forward for genetic engineering and synthetic biology, researchers have modified a strain of Escherichia coli bacteria to be immune to natural viral infections while also minimizing the potential for the bacteria or their modified genes to escape into the wild. The work promises to reduce the threats of viral contamination when...
Antibody fragment-nanoparticle therapeutic eradicates cancer
17.3.2023 | Press monitoring
A novel cancer therapeutic, combining antibody fragments with molecularly engineered nanoparticles, permanently eradicated gastric cancer in treated mice, a multi-institutional team of researchers found. The results of the "hit and run" drug delivery system, published in the March issue of Advanced Therapeutics, were the culmination of more...
Scientists transform algae into unique functional perovskites with tunable properties
15.3.2023 | Press monitoring
Scientists have transformed single-cell algae into functional perovskite materials. The team, led by scientists at the B CUBE–Center for Molecular Bioengineering at TU Dresden, converted mineral shells of algae into lead halide perovskites with tunable physical properties. The new perovskites have unique nano-architectures unachievable by...

Bacteria genetically engineered to seek and destroy tumors
13.3.2023 | Press monitoring
Cancer tumors are particularly adept at evading the body’s immune response, making treatment difficult. A new study has genetically engineered a common gut bacteria, enabling it to seek out and destroy cancer tumors from the inside. The chemokine CXCL16 recruits T cells, the white blood cells that help fight infection and cancer, to infiltrate...
A dozen exotic bacteria are found to passively collect rare earth elements from wastewater
10.3.2023 | Press monitoring
Rare earth elements (REEs) are a group of 17 chemically similar metals, which got their name because they typically occur at low concentrations (between 0.5 and 67 parts per million) within Earth's crust. Because they are indispensable in modern technology such as light-emitting diodes, mobile phones, electromotors, wind turbines, hard disks,...
Trapping and killing superbugs with novel peptide nanonets
8.3.2023 | Press monitoring
National University of Singapore (NUS) pharmaceutical scientists have developed synthetic peptide nanonets for treating infections by bacteria strains resistant to last-resort antibiotics. In nature, trap-and-kill is a common immune defense mechanism employed by various species, including humans. In response to the presence of pathogens, peptides...

Experimental vaccine reprograms cancer to launch immunotherapy attack
6.3.2023 | Press monitoring
Scientists have developed a new type of cancer vaccine that shows promise in clearing out leukemia in mice. The technique involves reprogramming cancer cells into immune cells so that they can teach the immune system how to fight off the disease. One of the most common forms of immunotherapy works by removing T cells from a patient, programming...

Novel robotic system can 3D print cells onto organs inside the body
3.3.2023 | Press monitoring
Engineers from UNSW have developed a miniature, flexible soft robotic arm that can be inserted into the body like an endoscope and deliver biomaterials directly onto the surface of organs and tissues. The proof-of-concept device, called F3DB, is externally controlled and comprises a long, flexible robotic arm, at the end of which sits a highly...
Lanpepsy is a novel protein that binds lanthanides with high specificity
1.3.2023 | Press monitoring
Rare-earth elements, also known as lanthanides, are, contrary to what the name suggests, not rare. They are, however, challenging to purify from the environment. Only in the past few years, it became evident that life has found solutions to harness these elements for itself. In a recent paper, the Vorholt lab describes the discovery of lanpepsy,...
Nanosatellite shows the way to RNA medicine of the future
27.2.2023 | Press monitoring
The RNA molecule is commonly recognized as messenger between DNA and protein, but it can also be folded into intricate molecular machines. An example of a naturally occurring RNA machine is the ribosome, that functions as a protein factory in all cells. Inspired by natural RNA machines, researchers at the Interdisciplinary Nanoscience Center...
