Novel graphene ribbons poised to advance quantum technologies

Sciencedaily.com 

Researchers have recently achieved a significant breakthrough in the development of next-generation carbon-based quantum materials, opening new horizons for advancements in quantum electronics. The innovation involves a novel type of graphene nanoribbon (GNR), named Janus GNR (JGNR). The material has a unique zigzag edge, with a special ferromagnetic edge state located on one of the edges. This unique design enables the realization of one-dimensional ferromagnetic spin chain, which could have important... Читать дальше...

Chemists unlock the potential of ketone and ester molecules, paving the way for greener and more efficient drug development

Sciencedaily.com 

Scientists have long considered ketones (a fundamental chemical class) and esters (molecules formed when an acid reacts with an alcohol) to be locked treasure chests of possibilities. Ubiquitous as pharmaceutical intermediates, ketones and esters are widely used for the synthesis of drug molecules. Yet both share a critical limitation: Generally, only two specific sites within their structure -- the carbonyl carbon and the alpha position -- are easily accessible to conventional chemical reactions.

Insights into the metabolism of the gut microbiota

Sciencedaily.com 

Researchers identified a protein and a group of small ribonucleic acids (sRNAs) in Bacteroides thetaiotaomicron, which regulate sugar metabolism. These discoveries shed light on how this gut microbe adapts to varying nutritional conditions. The findings deepen our understanding of this bacterium's role in the human gut and may pave the way for new therapeutic strategies to promote health through the microbiota.

Scientists identify genes driving cancer spread

Sciencedaily.com 

Cancer metastasis -- the spread of cancer to other organs -- is the leading cause of death among cancer patients. Researchers have now uncovered a 'genetic signature' of 177 genes shared across multiple cancer types that drives this deadly process.

Electric fungi: The biobattery that needs to be fed

Sciencedaily.com 

A battery that needs feeding instead of charging? This is exactly what researchers have achieved with their 3D-printed, biodegradable fungal battery. The living battery could supply power to sensors for agriculture or research in remote regions. Once the work is done, it digests itself from the inside.

Canada Throws Support Behind González Urrutia One Day Before Maduro’s Inauguration

«The Rio Times» 

Canada’s Foreign Affairs Minister, Mélanie Joly, has made a bold move in Venezuelan politics. On January 9, just one day before Nicolás Maduro’s planned self-inauguration, Joly recognized Edmundo González Urrutia as Venezuela’s president-elect. This decision directly challenges Maduro’s claim to power and legitimizes González Urrutia’s assertion of victory in the July elections. Joly’s announcement, made […]
