Researchers have succeeded in identifying and synthesizing a group of molecules that can act against the cause of tuberculosis in a new way. They describe that the so-called callyaerins act against the infectious disease by employing a fundamentally different mechanism compared to antibiotic agents used to date.

The NMDAR is involved in numerous cognitive functions including memory. Its movements are tightly coordinated like a choreographed dance routine. Scientists have now figured out how the protein performs a difficult 'Twist'-like dance move. The discovery could lead to new drug compounds that bind to NMDAR more effectively.

Physicists have been exploring the theoretical possibility of spaceships driven by compressing the four-dimensional spacetime for decades. Although this so-called 'warp drive' originates from the realm of science fiction, it is based on concrete descriptions in general relativity. A new study takes things a step further -- simulating the gravitational waves such a drive might emit if it broke down.

A research group has developed a new method that further improves the existing CRISPR/Cas technologies: it allows a more precise and seamless introduction of tags into proteins at the gene level. This technology could significantly improve research on proteins in living organisms and opens up new possibilities for medical research.

Two of the closest known relatives to SARS-CoV-2 -- a pair of bat coronaviruses discovered by researchers in Laos -- may transmit poorly in people despite being genetically similar to the COVID-19-causing virus, a new study reveals. The findings provide clues as to why some viruses have greater 'pandemic potential' than others and how researchers might go about identifying those that do before they become widespread.

Researchers have found that training successive generations of generative artificial intelligence models on synthetic data gives rise to self-consuming feedback loops.

Researchers develop a new type of rumor propagation model, taking inspiration from nuclear reactions. Their model can provide fresh insights on how online disinformation spreads and how to combat it. The team identified similarities between rumor spreading and fission, the reaction that occurs inside nuclear reactors. In their model, rumors act like neutrons, the small particles that kick off nuclear fission. These rumors are seen by individuals, who send them careening into other people in a chain reaction.

Nanozymes are tiny, engineered substances that mimic the catalytic properties of natural enzymes, and they serve a variety of purposes in biomedicine, chemical engineering, and environmental applications. They are typically made from inorganic materials, including metal-based elements, which makes them unsuitable for many purposes due to their toxicity and high production costs. Organic-based nanozymes partially overcome some of these problems and have the potential for a broader range of applications, including food and agriculture, but they are still in the early stages of development. A new paper provides an overview of the current state of organic nanozymes and their future potential.

Geneticists uncover new insights into how sex chromosome systems work in the platypus and the chicken -- which will lead to better understandings of our own sex chromosome evolution and gene regulation.

Researchers have modified certain bacteria with UV light so that they produce more cellulose. The basis for this is a new approach with which the researchers generate thousands of bacterial variants and select those that have developed into the most productive.

MicroRNAs can make plants more capable of withstanding drought, salinity, pathogens and more. However, in a recent study scientists showed just how much we didn't know about the intricate processes plants use to produce them.

New research using live mouse-adapted influenza virus improves upon previous mouse experiments to explain how maternal infection impacts fetal brain development. The study also indicates fetal brain changes are more likely once the severity of the mother's infection meets a specific threshold.
