When people are highly stressed for prolonged periods of time, they can sometimes experience a state known as burnout, characterized by pronounced emotional, mental and physical exhaustion. The stressors leading to burnout could be personal, such as family conflicts or the end of a relationship, as well as academic or professional, such as studying a lot for exams or working long hours while taking very few breaks or vacations. /news/2025-10-repetitive-negative-relationship-esteem-burnout.html Social Sciences Education Sun, 05 Oct 2025 09:00:01 EDT news678703984 A novel spectroscopic method developed at Institute of Science Tokyo, Japan, enables highly sensitive analysis of molecules at material interfaces, using a combination of conventional ATR-IR, precise gap-control and advanced data processing. The technique offers a low-cost alternative to conventional interfacial spectroscopy and has potential applications in material sciences, nanotechnology, and biological sciences. /news/2025-10-gap-infrared-method-enables-analysis.html Analytical Chemistry Fri, 03 Oct 2025 11:21:04 EDT news678709262 As people embrace ChatGPT and other large language models, University of Michigan anthropologist Webb Keane says it's easy for people to imbue AI with a human, or even god-like, authority. /news/2025-10-anthropologist-artificial-intelligence-authority.html Social Sciences Fri, 03 Oct 2025 07:06:04 EDT news678693961 Researchers have engineered a novel M6L4 octahedral molecular cage by integrating photoactive cyclometalated platinum(II) units, creating a visible-light-responsive "nanoreactor" that drives highly efficient photochemical reactions through precise molecular confinement. This innovative design overcomes the limitations of previous hosts, achieving perfect stereo- and site-selective cross-[2 + 2] cycloaddition reactions, and most notably, enabling catalytic cross-[2 + 2] cycloaddition of chemically inert substrates using this supramolecular confinement approach. /news/2025-10-nanoreactor-cage-visible-catalytic-ultra.html Nanomaterials Thu, 02 Oct 2025 13:30:02 EDT news678630366 Western cultures tend to view teens as moody, irresponsible, and rebellious.

But like all machines, these tiny devices need a source of power, the way electronic appliances use electricity or living cells use ATP (adenosine triphosphate, the universal biological energy source). /news/2025-10-rechargeable-powers-nanoscale-molecular-machines.html Bio & Medicine Nanophysics Wed, 01 Oct 2025 15:40:04 EDT news678552001 Metal-organic (MO) precursors are the chemical building blocks at the heart of atomically precise complex oxide materials. Yet in vapor-phase deposition techniques like MOCVD, ALD, and hybrid-MBE, they have long been treated as a "black box"—their reactions poorly understood and often dismissed as "just another knob to tweak." /news/2025-10-guesswork-decoding-metal-precursor-chemistry.html Analytical Chemistry Materials Science Wed, 01 Oct 2025 15:00:06 EDT news678549381 Researchers from the Skoltech Engineering Center's Hierarchically Structured Materials Laboratory, in collaboration with colleagues from MISIS University and the Joint Institute for Nuclear Research, have for the first time observed nanoscale transformations in ultra-high molecular weight polyethylene—a material possessing a shape memory effect—in real time. /news/2025-10-scientists-memory-smart-plastic.html Nanophysics Nanomaterials Wed, 01 Oct 2025 09:18:03 EDT news678529081 Women who are the first in their family to attend university have fewer children on average than graduates with at least one university-educated parent, UCL researchers find. /news/2025-09-generation-female-peers-children-40s.html Social Sciences Education Tue, 30 Sep 2025 09:51:04 EDT news678444662 The seemingly unpredictable, and thereby uncontrollable, dynamics of living organisms have perplexed and fascinated scientists for a long time.

This allows bacteria to rapidly evolve new traits, such as antibiotic resistance. A new study, led by Professor Indraneel Mittra at the Advanced Center for Treatment, Research & Education in Cancer, Mumbai, shows that this process may also happen in mammals—through fragments of DNA known as cell-free chromatin particles. /news/2025-09-uptake-dna-fragments-dying-cells.html Evolution Cell & Microbiology Thu, 25 Sep 2025 16:00:01 EDT news678031081 Machine-learning models can speed up the discovery of new materials by making predictions and suggesting experiments. But most models today only consider a few specific types of data or variables. Compare that with human scientists who work in a collaborative environment and consider experimental results, the broader scientific literature, imaging and structural analysis, personal experience or intuition, and input from colleagues and peer reviewers. /news/2025-09-ai-driven-blends-literature-robotics.html Analytical Chemistry Materials Science Thu, 25 Sep 2025 14:34:05 EDT news678029641 "If we act now and move with common purpose, then we can do more than just guard against the very worst.
