Capturing CO2 with electricity: A microbial enzyme inspires electrochemistry

Scientists have isolated a microbial enzyme that converts CO2 to formate with high efficiency when attached to an electrode, making it a potential candidate for capturing the greenhouse gas. The system uses renewable energy from wind or solar power to drive the conversion process, storing energy in the form of formate.

Why are killer whales harassing and killing porpoises without eating them?

Researchers analyzed 78 documented incidents of porpoise harassment by Southern Resident killer whales from 1962 to 2020. The study suggests three plausible explanations: mismothering behavior, limited opportunities to care for young due to malnutrition, and a specialized salmon diet that makes eating porpoises highly unlikely.

Specific interneurons are important in aging-associated cognitive decline, study finds

Researchers identify somatostatin-positive interneurons as crucial in maintaining cognitive function, and their dysfunction leads to impaired memory and learning. The study uses a toxin to ablate these cells, resulting in mice exhibiting cognitive deficits similar to those seen in aging humans.

Cannabis use disorder may be linked to increased risk of cardiovascular disease

A new study has found a significant association between cannabis use disorder and an increased risk of cardiovascular disease events such as heart attacks and strokes. Adults with cannabis use disorder in Canada experienced a 60% higher risk of first-time cardiovascular disease events compared to those without the disorder.

Learning critical Black history can change white perspectives on racism in health care

A UCLA study found that exposure to critical Black history can contribute to white people's recognition of health disparities faced by Black Americans and lead to support for policies aimed at equity. The study also found that perspective-taking, regardless of instruction, leads to greater recognition of racism in healthcare.

Researchers uncover why a gene mutant causes young children to have strokes

Researchers discovered that a mutation in the gene ACTA2 causes moyamoya disease and strokes in young children. The mutation leads to dysfunctional smooth muscle cells in arteries, resulting in blockages and increased risk of stroke. Understanding this mechanism could lead to new treatments for moyamoya disease.

University of Cincinnati research shows widespread naloxone distribution not enough to impact overdose death rate

A recent study by University of Cincinnati researchers found that a community-wide naloxone distribution program did not significantly reduce opioid overdose deaths. The study, which ran from 2017 to 2019, saw no significant change in median monthly opioid overdose rates despite widespread availability of the medication.
