Research reinvents MXene synthesis at a fraction of the cost‎

MXenes (pronounced like the name "Maxine") are a class of two-dimensional materials, first identified just 14 years ago, with remarkable potential for energy storage, catalysts, ultrastrong lightweight composites, and a variety of other purposes ranging from electromagnetic shielding to ink that can carry a current.

A short-lived kinase state that's essential for normal cell migration and T-cell function‎

Scientists at St. Jude Children's Research Hospital have characterized a hidden intermediate state at the center of Src kinase function. This hidden state allows the kinase to repeatedly modify its target, without needing to release and reattach to the target each time. The researchers have shown that this state is vital to T-cell activation and cell migration, emphasizing the importance of short-lived protein states to major biological processes and opening new avenues for targeting kinases therapeutically.

'AI advisor' helps self-driving labs share control in creation of next-generation materials‎

"Self-driving" or "autonomous" labs are an emerging technology in which artificial intelligence guides the discovery process, helping design experiments or perfecting decision strategies.

Private donors pledge $1 billion for world's largest particle accelerator‎

Europe's physics lab CERN on Thursday said private donors had pledged $1 billion toward the construction of a new particle accelerator that would be by far the world's biggest.

Newly discovered microbes challenge assumptions about methane production in the environment‎

It's been known for nearly a century that swarms of single-celled organisms thrive by consuming chemicals from their environments and expelling methane gas as a byproduct. In 2024, researchers in the laboratory of Roland Hatzenpichler, associate professor in the Department of Chemistry and Biochemistry in Montana State University's College of Letters and Science, published the first-ever descriptions of methane-producing microbes outside the lineage Euryarchaeota, which—in a study published on the bioRxiv preprint server—they have confirmed to be ubiquitous in the environment.

Hybrid excitons: Combining the best of both worlds‎

Faster, more efficient, and more versatile—these are the expectations for the technology that will produce our energy and handle information in the future. But how can these expectations be met? A major breakthrough in physics has now been made by an international team of researchers from the Universities of Göttingen, Marburg, the Berlin Humboldt in Germany, and Graz in Austria.

Life on lava: How microbes colonize new habitats‎

Life has a way of bouncing back, even after catastrophic events like forest fires or volcanic eruptions. While nature's resilience to natural disasters has long been recognized, not much is known about how organisms colonize brand-new habitats for the first time. A new study led by a team of ecologists and planetary scientists from the University of Arizona provides glimpses into a poorly understood process.

Survey of researchers shows active AI adoption for core scientific tasks‎

A new study provides answers based on a survey with more than 6,000 researchers from the Max Planck Society and the Fraunhofer Society. The highlights: Researchers actively use AI, including for core and creative research tasks. The gender gap in AI use largely reflects differences in familiarity, not attitudes. Researchers cite legal uncertainty as a major barrier to AI adoption.

Bazinga! Physicists crack a 'Big Bang Theory' problem that could help explain dark matter‎

A professor at the University of Cincinnati and his colleagues have figured out something two of America's most famous fictional physicists couldn't: how to theoretically produce subatomic particles called axions in fusion reactors.

Hidden viruses: Amoebae as a water safety 'Trojan horse'‎

Human norovirus and adenovirus, two major causes of viral gastroenteritis, can persist for extended periods inside free-living amoebas that are common in natural and engineered water systems. A newly published study shows that these gut viruses can "hide" within different stages of the amoebas and remain capable of causing infection after this detour.
