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...

Antibody-producing yeast vanquishes deadly gut infection in mice

30.10.2020   |   Press monitoring

When people take antibiotics for one infection, another can swoop in to take its place: the bacterium Clostridioides difficile, which causes severe, recurring colon infections that kill nearly 30,000 people annually in the United States, most over the age of 65. Now, researchers have a new idea for battling C. diff: They have modified yeast to...

Bullet-like nanoparticles heat and destroy cancer cells from the inside

28.10.2020   |   Press monitoring

A research team in the UK have demonstrated how an adaptation of this technology can be used to tackle mesothelioma, a hard-to-treat cancer caused by asbestos exposure, with a little help from laser light. The work was carried out by scientists from the University of Cambridge and the University of Leeds and uses nanoparticles made from gold,...

Researchers complete world first wasp genome project

26.10.2020   |   Press monitoring

In a world first, New Zealand researchers have sequenced the genome of three wasps, two of which are invasive wasps in New Zealand, paving the way for new methods of control for these significant pests. Genomics Aotearoa researchers working at the University of Otago and Te Herenga Waka–Victoria University of Wellington, alongside colleagues from...

Repairing the photosynthetic enzyme Rubisco

23.10.2020   |   Press monitoring

The enzyme Rubisco catalyzes the assimilation of CO2 from the atmosphere into organic matter. This is the central step in photosynthesis that generates sugar molecules for the production of essentially all biomass. Despite its pivotal role, Rubisco works relatively slowly and is easily inhibited by sugar products. By improving the function of...

CRISPR meets Pac-Man: New DNA cut-and-paste tool enables bigger gene edits

21.10.2020   |   Press monitoring

Gene editing for the development of new treatments, and for studying disease as well as normal function in humans and other organisms, may advance more quickly with a new tool for cutting larger pieces of DNA out of a cell's genome, according to a new study by UC San Francisco scientists. The already renowned CRISPR-Cas9 ensemble is like a...
