A DNA-based nanogel for targeted chemotherapy
23.11.2020 | Press monitoring
Current chemotherapy regimens slow cancer progression and save lives, but these powerful drugs affect both healthy and cancerous cells. Now, researchers reporting in ACS' Nano Letters have designed DNA-based nanogels that only break down and release their chemotherapeutic contents within cancer cells, minimizing the impacts on normal ones and...

Microbe rewiring technique promises a boom in biomanufacturing
20.11.2020 | Press monitoring
Researchers from Lawrence Berkeley National Laboratory (Berkeley Lab) have achieved unprecedented success in modifying a microbe to efficiently produce a compound of interest using a computational model and CRISPR-based gene editing. Their approach could dramatically speed up the research and development phase for new biomanufacturing processes,...
Decoy molecule draws deadly mosquito-borne virus away from the brain
18.11.2020 | Press monitoring
Venezuelan equine encephalitis virus (VEEV) is a mosquito-borne virus that, in the worst case scenario, can infect the brain and become deadly. It’s notoriously difficult to treat, but now scientists have discovered the protein it latches onto – and used it to create a decoy molecule that draws the virus away from the brain. Originating in...

Monster tumors could offer new glimpse at human development
16.11.2020 | Press monitoring
Finding just the right model to study human development – from the early embryonic stage onward – has been a challenge for scientists over the last decade. Now, bioengineers at the University of California San Diego have homed in on an unusual candidate: teratomas. Teratomas – which mean "monstrous tumors" in Greek – are tumors made up of...

Sorting out viruses with machine learning
13.11.2020 | Press monitoring
The ongoing global pandemic has created an urgent need for rapid tests that can diagnose the presence of the SARS-CoV-2 virus, the pathogen that causes COVID-19, and distinguish it from other respiratory viruses. Now, researchers from Japan have demonstrated a new system for single-virion identification of common respiratory pathogens using a...

Scientists use bacteria as micro-3-D printers
11.11.2020 | Press monitoring
A team at Aalto University has used bacteria to produce intricately designed three-dimensional objects made of nanocellulose. With their technique, the researchers are able to guide the growth of bacterial colonies through the use of strongly water repellent – superhydrophobic – surfaces. The objects show tremendous potential for medical use,...
Scientists Infect Lab-Grown Mini-Lungs With SARS-CoV-2
9.11.2020 | Press monitoring
A team of researchers have developed a mini-lung in the lab made of thousands of human lung stem cells. This breakthrough is now being used to understand what SARS-CoV-2 and other airborne pathogens do to our lung cells. The team used alveolar epithelial type-2 cells (AT2s), a type of lung stem cell that repairs the deepest portions of our...
Researchers develop artificial cell on a chip
6.11.2020 | Press monitoring
Researchers at the University of Basel have developed a precisely controllable system for mimicking biochemical reaction cascades in cells. Using microfluidic technology, they produce miniature polymeric reaction containers equipped with the desired properties. This 'cell on a chip' is useful not only for studying processes in cells, but also...
Root bacterium to fight Alzheimer\'s: Rhizolutin dissociates beta and tau aggregates
4.11.2020 | Press monitoring
A bacterium found among the soil close to roots of ginseng plants could provide a new approach for the treatment of Alzheimer's. Rhizolutin, a novel class of compounds with a tricyclic framework, significantly dissociates the protein aggregates associated with Alzheimer's disease both in vivo and in vitro. A team working with YoungSoo Kim...
Ultrapotent COVID-19 vaccine candidate designed via computer
2.11.2020 | Press monitoring
An innovative nanoparticle vaccine candidate for the pandemic coronavirus produces virus-neutralizing antibodies in mice at levels ten-times greater than is seen in people who have recovered from COVID-19 infections. Designed by scientists at the University of Washington School of Medicine in Seattle, the vaccine candidate has been transferred to...
