Keeping SARS-CoV-2 closed for business with small molecules      (via sciencedaily.com) 

The infamous spike proteins on the surface of SARS-CoV-2 help it bind to and enter human cells. Because of their important role in spreading infection, these spike proteins are one of the main targets for COVID-19 vaccines and treatments. But those remedies gradually lose effectiveness when certain segments of the spike proteins mutate. Now, researchers report that they have discovered small molecules that successfully target other segments that mutate less.

This one-atom chemical reaction could transform drug discovery      (via sciencedaily.com) 

Researchers have used single carbon atom doping to form four chemical bonds in one step. Gamma-lactams (cyclic molecules that are common in antibiotics) were easily synthetically accessible from alpha, beta-unsaturated amides (an important molecule in cancer progression). The team chemically modified an anti-seizure medication in 96% yield, highlighting the work's utility to otherwise synthetically complex aspects of pharmaceutical development. The results of this work could become foundational to drug discovery and development.

Using CRISPR to detect cancer biomarkers      (via sciencedaily.com) 

Most cancer diagnostic techniques rely on uncomfortable and invasive procedures, such as biopsies, endoscopies or mammograms. Blood samples could be a less unpleasant option, though only a few forms of the disease can currently be diagnosed this way. But now, researchers have developed an easy-to-use method that can detect small amounts of cancer-related molecules in exosomes in plasma and effectively distinguish between malignant and benign samples.

'Snapshots' of translation could help us investigate cellular proteins      (via sciencedaily.com)     Original source 

Nascent polypeptide chains or polypeptidyl-tRNAs (pep-tRNAs) occur transiently during protein synthesis. The potential to study these intermediates and better understand their role in processes like gene regulation has been greatly enhanced by the development of a process termed PETEOS -- short for peptidyl-tRNA enrichment using organic extraction and silica adsorption. This method allows for the large-scale harvesting, processing, and identification of pep-tRNA polypeptide moieties.

Researchers create smaller, cheaper flow batteries for clean energy      (via sciencedaily.com) 

Flow batteries offer a solution. Electrolytes flow through electrochemical cells from storage tanks in this rechargeable battery. The existing flow battery technologies cost more than $200/kilowatt hour and are too expensive for practical application, but engineers have now developed a more compact flow battery cell configuration that reduces the size of the cell by 75%, and correspondingly reduces the size and cost of the entire flow battery. The work could revolutionize how everything from major commercial buildings to residential homes are powered.
