Micromotors that Swim and Sequester Carbon Dioxide

Researchers from UC San Diego have developed an innovative tool to fight climate change. In their study, published in the journal Angewandte Chemie, the team lead by Dr. Joseph Wang constructed tube-shaped micromotors functionalized with enzymes that sequester carbon dioxide and a platinum layer to propel them in the water. Antropogenic carbon dioxide generation is […]

A Single Cas Protein for Gene Edition and Regulation

CRISPR-Cas9 is know for its ability to edit eukaryotic genomes, but from now it could be famous for its multifunctionality. MIT and Harvard laboratories have led a research project that transforms CRISPR-Cas9 into a gene activator/repressor. The researchers altered the length of the guide RNA (gRNA) that directs the nuclease to its target, which resulted in a new ability: the […]

Monobodies: Little Molecules that Alter Enzymatic Activity

Enzymatic activity can now be modified without altering the enzyme. Researchers at the University of Chicago changed the specificity of an enzyme, commonly used in the food industry, with synthetic proteins they called monobodies. The discovery, published in Nature Chemical Biology, opens the door to fine-tuning dozens of molecular reactions with commercial applications. Enzymes are […]

Plastics made of methane threaten oil industry

Plastics are a multibillionaire industry dependent on oil, but this can change soon. Newlight Technologies takes methane emissions and turn them into AirCarbon™ thermoplastic. The innovative carbon capture technology poses a serious threat to the oil industry and can help reduce fossil fuel extraction and gas emission. In 2003, Princeton undergraduate Mark Herrema read an […]

Genetically Modified Yeast Accelerates Drug Production

Scientists from Stanford have modified the genome of the yeast Saccharomyzes cerevisiae to produce the painkiller hydrocodone. The process is cheaper and faster than obtaining the opioids from the plant. The achievement was published in Science. Opioids are a family of painkillers extracted from the opium poppy. Hydrocodone, oxycodone and morphine are some of the opioids obtained in […]

Cyanobacteria Produce Industrial Enzymes Sustainably

Scientists from Ruhr-Universität Bochum (RUB) have successfully produced biocatalysts from cyanobacteria, microorganisms that only consume water, salts, CO2 and light. The finding, published in the journal Microbial Cell Factories, is a major step towards a sustainable chemical industry. The global economy, based on ever-increasing production of goods, is bringing the natural system to its limit. […]

Bacterial Enzyme Might Help Quit Smoking

Researchers from The Scripps Research Institute (TSRI) in La Jolla, CA have discovered a bacterial enzyme that degrades nicotine. The enzyme has been tested in vitro and could be used in the future to break down nicotine in the body before it reaches the brain. The finding was published in JACS.Smoking is the main cause […]

NEB Releases a Thermostable Reverse Transcriptase

New England Biolabs has released the WarmStart® RTx, an in silico-engineered thermostable reverse transcriptase optimized for speed, sensitivity and inhibitor resistance. The new reverse transcriptase has been designed for detection of very small RNA quantities in complex samples. The WarmStart® RTx is reversibly inhibited at room temperature due to coupling with a reversibly-bound aptamer. Room […]
