Changes in blood vessels are the major cause of death and morbidity in diabetes. For the first time, scientists managed to grow perfect human blood vessels as organoids in a petri dish. This breakthrough engineering technology dramatically advances research of vascular dysfunction in diseases ...
Penetrate of living tissue and other materials without damage by high-intensity light exposure
Columbia University scientists, in collaboration with researchers from Harvard, have succeeded in developing a chemical process to convert visible light into infrared energy, allowing innocuous radiation to penetrate living tissue and other materials without the damage caused by high-intensity ...
Limiting the impact of schistosomiasis and liver fluke infection
For the first time, researchers at the George Washington University (GW), together with colleagues at institutes in Thailand, Australia, the U.K. and the Netherlands, and more, have successfully used the gene-editing tool CRISPR/Cas9 to limit the impact of parasitic worms responsible for ...
Ammonia synthesis through electroreduction of nitrogen on black phosphorus nanosheets
More than 100 years after the introduction of the Haber–Bosch process, scientists continue to search for alternative ammonia production routes that are less energy demanding. Chinese scientists have now discovered that black phosphorus is an excellent catalyst for the electroreduction of nitrogen ...
A simple new tweak could double the efficiency of organic electronics
The majority of our everyday electronics are based on inorganic semiconductors, such as silicon. Crucial to their function is a process called doping, which involves weaving impurities into the semiconductor to enhance its electrical conductivity. It is this that allows various components in ...
Organ transplant rejection is a major problem in transplantation medicine. Suppressing the immune system to prevent organ rejection, however, opens the door to life-threatening infections. Researchers at the University of Basel’s Biozentrum have now discovered a molecular approach preventing ...
Doing More with Less
In adults, mesenchymal stems cells (MSCs) are primarily found in bone marrow and they play a vital role in repair of damaged organs. The transformation of a single MSC into complex tissue like cartilage and bone starts with its association with other MSCs in order to form microscopic clusters via ...
Drug screening with Mobile-CRISPRi
A University of Wisconsin-Madison researcher and his collaborators at the University of California, San Francisco have repurposed the gene-editing tool CRISPR to study which genes are targeted by particular antibiotics, providing clues on how to improve existing antibiotics or develop new ...
Smaller ammonia processing plants powered by alternative energy
Ammonia, a compound first synthesized about a century ago, has dozens of modern uses and has become essential in making the fertilizer that now sustains most of our global food production. But while we've been producing ammonia at a large scale since the 1930s, it has been accomplished mainly in ...
The classic molecular-biological narrative has a simple form: Gene-RNA-protein. This is what we learned in school: DNA is transcribed into RNA. In the protein factories (the so-called ribosomes), the RNA serves as a kind of punch card - the proteins are assembled by the machinery exactly ...
q&more – the networking platform for quality excellence in lab and process
The q&more concept is to increase the visibility of recent research and innovative solutions, and support the exchange of knowledge. In the broad spectrum of subjects covered, the focus is on achieving maximum quality in highly innovative sectors. As a modern knowledge platform, q&more offers market participants one-of-a-kind networking opportunities. Cutting-edge research is presented by authors of international repute. Attractively presented in a high-quality context, and published in German and English, the original articles introduce new concepts and highlight unconventional solution strategies.
