Hierarchically porous carbon networks embedded with single iron sites for efficient oxygen reduction
Currently, oxygen reduction reaction (ORR) suffers from sluggish kinetics and high overpotential, which usually requires costly platinum (Pt)-based materials. Transition metal single-atom catalysts (M–N–C), such as Fe–N4 and Co–N4 with high O.....»»
In storms like Hurricane Helene, flooded industrial sites and toxic chemical releases are a silent and growing threat
Hundreds of industrial facilities with toxic pollutants were in Hurricane Helene's path as the powerful storm flooded communities across the Southeast in late September 2024......»»

Here’s how the Apple Watch blood oxygen feature could return after Masimo shakeup
One of the biggest barriers to upgrading to a new Apple Watch this year is that, if you’re in the US and currently own a model with blood oxygen measurement, you wouldn’t get that feature in your new model. That’s due to the patent dispute b.....»»
Researchers use carbon nanotube derivatives to strengthen recyclable plastics
Reducing the environmental impact caused by plastics can be addressed through different strategies, such as the manufacture of more durable plastics or recycling. In general, there are two main types of plastics. The first is thermoplastics, which ca.....»»
New copper metal-organic framework nanozymes enable intelligent food detection

A new apparatus for analyzing partial coherence in integrated photonic networks
Anyone familiar with optics labs is familiar with the extremes of light coherence: laser beams are highly coherent, producing clear interference patterns used for precise applications like atomic manipulation or precise sensing. In contrast, light fr.....»»
Inland waters crucial for accurate climate assessments, research suggests
Inland waters release substantial amounts of greenhouse gases, but this is rarely included in climate assessments. New research from Umeå University shows that not accounting for carbon fluxes between land and water systems leads to incorrect assess.....»»

As AI continues to embed itself into our everyday lives and, now, Apple getting into the AI game with Apple Intelligence, the need for more intelligent, efficient tools is growing. With so much data to process, especially in PDFs, finding a solution.....»»
Breathing may introduce microplastics to the brain—new study
Small plastic particles are everywhere: in the soil where our food is grown, in the water we drink and in the air we breathe. They got there from the plastic we throw away, which ends up in landfill sites, rivers and seas. There the plastic waste slo.....»»

Ryugu samples call into question previous ideas about the formation of carbon-rich asteroids
Asteroid Ryugu possibly did not travel as far from its place of origin to its current near-Earth orbit as previously assumed. New research published in the journal Science Advances suggests that Ryugu was formed near Jupiter......»»
Exploring the role of hydrogen sulfide in the expression of iron uptake genes in E. coli
Antibiotic resistance and oxidative stress response are important biological mechanisms that help bacteria thrive, especially pathogenic bacteria like Escherichia coli. Hydrogen sulfide (H2S), a chemical messenger molecule, regulates several intracel.....»»
