Theoretical perspective on C-H/O-H activation by Cu-O in biological and synthetic systems
Dioxygen activations constitute one of the core issues in copper-dependent metalloenzymes. Upon O2 activation, copper-dependent metalloenzymes, including particulate methane monooxygenases (pMMOs), lytic polysaccharide monooxygenases (LPMOs) and binu.....»»
Scientists develop a new model of electric double layer
A new model accounts for a wide range of ion-electrode interactions and predicts a device's ability to store electric charge. The model's theoretical predictions align with the experimental results. Data on the behavior of the electric double layer (.....»»
Scientists highlight overlooked threats to Arctic coasts amid climate change
As climate change rapidly transforms Arctic marine systems, the dramatic image of a polar bear struggling on a melting ice floe has become symbolic of the region's environmental crisis. But scientists argue that coastal Arctic ecosystems are undergoi.....»»
Halcyon offers ransomware protection for Linux environments
As an integral part of the Halcyon Anti-Ransomware Platform, Halcyon Linux offers protection against ransomware attacks targeting Linux systems. While ransomware operators were once almost exclusively focused on targeting Windows environments, the in.....»»

Ransomware attackers hop from on-premises systems to cloud to compromise Microsoft 365 accounts
Storm-0501, an affiliate of several high-profile ransomware-as-a-service outfits, has been spotted compromising targets’ cloud environments and on-premises systems. “Storm-0501 is the latest threat actor observed to exploit weak credentia.....»»
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.....»»
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.....»»
CUPS vulnerabilities affecting Linux, Unix systems can lead to RCE
