Scientists report incredibly small time delays in a molecule's electron activity when the particles are exposed to X-rays. To measure these tiny high-speed events, known as attoseconds, researchers used a laser to generate intense X-ray flashes that allowed them to map the inner workings of an atom.

An artificial intelligence algorithm can allow researchers to more efficiently use 3D printing to manufacture intricate structures. The development could allow for more seamless use of 3D printing for complex designs in everything from artificial organs to flexible electronics and wearable biosensors. As part of the study, the algorithm learned to identify, and then print, the best versions of kidney and prostate organ models, printing out 60 continually improving versions.

Scientists have engineered a highly selective catalyst that can convert methane, a major component of natural gas, into methanol, an easily transportable liquid fuel, in a single, one-step reaction. This direct process for methane-to-methanol conversion runs at a temperature lower than required to make tea and exclusively produces methanol without additional byproducts.

Who are we? Why are we here? We are stardust, the result of chemistry occurring throughout vast clouds of interstellar gas and dust. To better understand how that chemistry could create prebiotic molecules, researchers investigated the role of low-energy electrons created as cosmic radiation traverses through ice particles. Their findings may also inform medical and environmental applications on our home planet.

In the scorching heat of summer, anyone who spends time outside could benefit from a cooling fabric. While there are some textiles that reflect the sun's rays or wick heat away, current options require boutique fibers or complex manufacturing processes. But now, demonstrations of a durable chalk-based coating show it can cool the air underneath treated fabric by up to 8 degrees Fahrenheit.

The distribution of outermost shell electrons, known as valence electrons, of organic molecules was observed for the first time. As the interactions between atoms are governed by the valence electrons, the findings shine light on the fundamental nature of chemical bonds, with implications for pharmacy and chemical engineering.

Researchers have succeeded in forming metal-organic framework thin films on a substrate while controlling the growth direction of crystals so that they are arranged neatly without gaps. The resulting thin films of unprecedented high quality can be expected for use as optical sensors, optical elements, and transparent gas adsorption sheets.

Bioengineers around the world have been working to create plastic-producing microbes that could replace the petroleum-based plastics industry. Now, researchers have overcome a major hurdle: getting bacteria to produce polymers that contain ring-like structures, which make the plastics more rigid and thermally stable. Because these molecules are usually toxic to microorganisms, the researchers had to construct a novel metabolic pathway that would enable the E. coli bacteria to both produce and tolerate the accumulation of the polymer and the building blocks it is composed of. The resulting polymer is biodegradable and has physical properties that could lend it to biomedical applications such as drug delivery, though more research is needed.

Artificial intelligence (AI) has exploded in popularity as of late. But just like a human, it's hard to read an AI model's mind. Explainable AI (XAI) could help us do just that by providing justification for a model's decisions. And now, researchers are using XAI to scrutinize predictive AI models more closely, which could help make better antibiotics.

Some of the attractive hues of brightly colored, cloth-bound books from the Victorian era come from dyes that could pose a health risk to readers, collectors or librarians. The latest research on these 'poison books' used three techniques -- including one that hasn't previously been applied to books -- to assess dangerous dyes in a university collection and found some volumes had levels that might be unsafe.
