Raising human capital in BRICS is linked to lower emissions, study suggests‎

Climate change and worsening environmental conditions have brought into sharp relief how we must reconcile development with sustainability. This issue is nowhere more starkly relevant than among the fastest-growing economies. Research published in the International Journal of the Energy-Growth Nexus that examined the BRICS countries, Brazil, Russia, India, China and South Africa, suggests that investment in education and training might play a significant role in reducing environmental harm, a role that has often been overlooked.

Light-driven probe enables sensitive detection of epigenetic intermediates‎

Epigenetic modifications such as DNA methylation play a key role in regulating gene expression. Emerging evidence suggests that intermediates generated during DNA demethylation may have distinct biological roles. However, their detection remains challenging due to their low abundance. Now, researchers from Japan have developed a novel light-sensitive oligonucleotide probe that selectively crosslinks with 5-formylcytosine, an epigenetically important intermediate, enabling its detection in target DNA and complex biological samples.

Study: Why Nobel Prize-level materials have yet to reach industry‎

Excess carbon dioxide in the atmosphere, polluted water, and increasingly strict environmental regulations are driving the search for materials that can efficiently trap pollutants at the molecular level. For more than two decades, this challenge has drawn scientific attention to metal–organic frameworks (MOFs)—highly advanced porous materials widely regarded as one of the most promising tools for tackling climate change and environmental pollution.

Into the neutrino fog: The ghosts haunting our search for dark matter‎

Ciaran O'Hare scribbles symbols using colored markers across his whiteboard like he's trying to solve a crime—or perhaps planning one. He bounces around the edges of the board, slowly filling it with sharp angles and curling letters. I watch on, and when he senses I'm losing track, he pauses intermittently, allowing my brain to catch up. Ciaran speaks with an easy to understand British inflection, but the language on the whiteboard might as well be hieroglyphics.

Governments urged to fix faulty radar in economic models disregarding climate risk‎

Economic models used by governments, central banks and investors are increasingly understating physical climate risk because they rely on assumptions that break down as the world moves toward higher levels of warming, according to a new report from University of Exeter and Carbon Tracker. The report Recalibrating Climate Risk—drawing on expert judgment from more than 60 climate scientists—finds that many economic models are failing to capture the extreme events, compounding shocks and rising uncertainty likely to dominate impacts in a hotter world.

Large study shows scaling startups risk increasing gender gaps‎

When startups scale quickly, founders often make hurried hiring decisions that unintentionally disadvantage women, according to new study from the Stockholm School of Economics in Sweden. The study shows how the pressures of rapid growth increase the likelihood that founders rely on mental shortcuts and make biased decisions. The study is published in the journal Human Resource Management.

New VRscores database maps workplace politics across 530,000 US employers‎

Researchers, including Professor of Management and Organization Reuben Hurst at the University of Maryland's Robert H. Smith School of Business, have produced VRscores, an unprecedented public database for understanding the partisan lean of different employers in the United States.

What Olympic athletes see that viewers don't: Machine-made snow makes ski racing faster and riskier‎

When viewers tune in to the 2026 Winter Olympics, they will see pristine, white slopes, groomed tracks and athletes racing over snow-covered landscapes, thanks in part to a storm that blanketed the mountain venues of the Italian Alps with fresh powder just in time.

Why cheaper power alone isn't enough to end energy poverty in summer‎

Australia is an energy superpower. We have abundant natural resources, high average incomes and one of the highest per-capita rates of rooftop solar uptake in the world.

'Dispersal-driven' evolution fuels diversity at the air-liquid interface‎

As in a batch of kombucha or a barrel of sherry, microbes can assemble into a mat-like layer at the boundary between air and liquid. In laboratory culture, the bacterium Pseudomonas fluorescens SBW25 is widely known for doing exactly that: starting from a non-mat-forming original type, it evolves—through genetic mutations—into forms that construct a mat at the air–liquid interface, and it does so with striking regularity within just a few days.
