Job hopping builds hidden 'mobility benefit'‎

A history of job changes could be a red flag on a résumé, or it could signal a job candidate with an important "mobility benefit" that will help them begin a new job, says new research from Rebecca Kehoe, professor of Human Resources Studies in Cornell's ILR School.

New enzyme atlas rewrites decades of biology research‎

WEHI researchers have led a major global effort to create the first authoritative atlas for a class of enzymes that regulate almost every cellular process in the human body. Published in Cell, the study establishes the first gold-standard reference for all human E3 ligases, resolving nearly two decades of inconsistencies within the field.

Study finds emissions cuts can mask lack of systemwide change toward climate neutrality‎

Many countries have adopted ambitious climate protection targets, typically measuring progress through emissions reductions and the expansion of renewable energy. But according to a research team led by Germán Bersalli of the Research Institute for Sustainability, such indicators offer only limited insight. In Current Research in Environmental Sustainability, the researchers introduce a method designed to better capture the underlying drivers of change and apply it to four European countries. Their findings reveal a consistent pattern: despite measurable advances, none of the countries has yet achieved the comprehensive, system-wide transformation required for a fully CO₂-free energy system.

Lab-based mini-atmosphere reveals how turbulence changes on different scales‎

With a new lab-based experiment, researchers in the UK and France have recreated the characteristic cascades of energy and angular momentum that underpin key features of Earth's atmosphere. Reporting in Physical Review Letters, a team led by Peter Read at the University of Oxford has gained fresh insights into how energy fluctuations in turbulent flows are linked to their size, while also uncovering behaviors that current atmospheric models can't yet explain.

How AI English and human English differ—and how to decide when to use artificial language‎

Suspicion and affection. Apprehension and excitement. Most people have mixed feelings about AI English, whether or not they always recognize it. When reading text generated by AI, people feel it sounds off, or fake. When reading English by a human, people are more likely to feel it has a characteristic voice or a personal touch.

North Sea wind farms may be reshaping sediment flows by 1.5 million tons a year‎

Offshore wind farms are an important pillar of the European Union's strategy for renewable energy—by 2050, the EU aims to increase capacity in the North Sea more than tenfold. A new study by the Helmholtz-Zentrum Hereon shows that the expansion of wind farms can alter the natural transport and deposition of sediments on a large scale and over the long term. The German Bight is particularly affected. The researchers have published their findings in the journal Nature Communications Earth & Environment.

AI-driven framework uncovers new carbon structures—one thought to be harder than diamond‎

Through new improvements to existing AI models, researchers in China have created a framework that can methodically identify useful new forms of solid carbon. With their approach, Zhibin Gao and colleagues at Xi'an Jiaotong University hope that numerous new materials could be discovered, exhibiting combinations of exotic properties that are inaccessible via conventional search methods.

The raccoon raiding your garbage bin might just be solving a puzzle—for the fun of it‎

Ever woken up to find that a crafty raccoon has overturned your garbage bin and spread the discarded contents of your life across the street? Raccoons—sometimes referred to as "trash pandas"—are renowned as excellent innovators and problem-solvers who can often find their way through the trickiest barriers in their search for food.

Ancient DNA finds 15,800-year-old dogs in Anatolia, buried like humans‎

Evidence of some of the earliest dogs has been identified at two University of Liverpool/British Institute at Ankara archaeological excavation projects in central Anatolia, Turkey. Shedding new light on the development and spread of early domestic dogs, the findings are documented in two papers published in Nature.

Chemists harness electricity to create biomass-based building blocks‎

Chemists at Wageningen University & Research (WUR) and Utrecht University have developed a new method to produce a promising chemical building block from biomass. This compound can serve as a precursor for useful products such as plastics, pharmaceuticals, and flavor and fragrance ingredients. Conventionally, its production requires hazardous chemicals. The Dutch research team now demonstrates that the process can instead be driven by electricity, using a simple setup and without the addition of dangerous chemicals. They published the results in ChemSusChem.
