A team of Rutgers University scientists dedicated to pinpointing the primordial origins of metabolism – a set of core chemical reactions that first powered life on Earth – has identified part of a protein that could provide scientists clues to detecting planets on the verge of producing life.

The research, published on March 10 in the journal Science Advances.

<em>Science Advances</em> is a peer-reviewed, open-access scientific journal that is published by the American Association for the Advancement of Science (AAAS). It was launched in 2015 and covers a wide range of topics in the natural sciences, including biology, chemistry, earth and environmental sciences, materials science, and physics.

Genetic Engineering extends far beyond the controversial news headlines that obsess over ‘designer babies’. In the science community, gene-editing tools like CRISPR and PRIME editing will do nothing less than save the planet.

A semirigid stamp and a standard photolithography mask-aligner enable a reliable and scalable pickup and release process for van der Waals materials integration at the wafer scale.

Harvard Medical School professor Michael E. Greenberg has won The 2023 Brain Prize for his decades-long research on brain plasticity, alongside University of Cambridge professor Christine E. Holt and Max Planck Institute Director Erin M. Schuman.

Nucleic acid sensing involving CRISPR technologies is powerful but has certain limitations, such as PAM sequence requirements and limited multiplexing. Here, authors report a CRISPR-based barcoding technology which enables multiple outputs from any target sequence, based on cis-and trans-cleavage.

Researchers led by Prof. Zhou Wu from the University of Chinese Academy of Sciences (UCAS) and Prof. Sokrates T. Pantelides of Vanderbilt University have pushed the sensitivity of single-atom vibrational spectroscopy to the chemical-bonding-configuration extreme, which is critical for understanding the correlation of lattice vibrational properties with local atomic configurations in materials.

Using a combination of experimental and theoretical approaches, the researchers demonstrated the effect of chemical-bonding configurations and the atomic mass of impurity atoms on local vibrational properties at the single-atom level.

The study was published in Nature Materials.

A research team led by Prof. Xue Yuanchao from the Institute of Biophysics of the Chinese Academy of Sciences has developed a new method for global profiling of in-situ RNA–RNA contacts associated with a specific RNA-binding protein (RBP) and revealed positional mechanisms by which PTBP1-associated RNA loops regulate cassette exon splicing.

This study was published online in Molecular Cell on March 22.

In eukaryotes, the same pre-mRNA can produce multiple protein isoforms to execute similar or different biological functions through alternative splicing. Several longstanding models proposed that RBPs may regulate alternative splicing by modulating long-range RNA–RNA interactions (RRI). However, direct experimental evidence was lacking.

The secret to a perfect croissant is the layers—as many as possible, each one interspersed with butter. Similarly, a new material with promise for new applications is made of many extremely thin layers of metal, between which scientists can slip different ions for various purposes. This makes them potentially very useful for future high-tech electronics or energy storage.

Until recently, these materials—known as MXenes, pronounced “max-eens”—were as labor-intensive as good croissants made in a French bakery.

But a new breakthrough by scientists with the University of Chicago shows how to make these MXenes far more quickly and easily, with fewer toxic byproducts.

The coolest concept of 2022 might become more than a concept if this VP has his way.
