More than a reflex: How the spine shapes sex

The study found that a specific spinal circuit is involved in both ejaculation and arousal, and integrates sensory inputs to adjust its output based on the animal's internal state. The researchers also discovered that Gal⁺ neurons receive sensory input from the penis and can trigger ejaculation, but their effects are suppressed by brai...

USTC deciphers temperature-governed processes of lithium-mars gas batteries

Researchers from USTC deciphered the temperature-governed processes of lithium-mars gas batteries, finding that temperature regulates a balance between two-electron and four-electron processes. Low temperatures cause interface passivation, while high temperatures stimulate decomposition efficiency through the generation of highly activ...

Toward objective diagnostics in depression: blood metabolomics for symptom profiling, suicide risk, and personalized psychiatry

A review explores how blood-based metabolomics can provide objective biomarkers for depressive states, suicidal ideation, and treatment responsiveness in depression. Metabolites such as 3-hydroxybutyrate and citrate have shown reproducible associations with depressive severity across multiple clinical cohorts.

Immunoblot assay shows comparable accuracy to ELISA in detecting anti-F-actin antibodies for autoimmune hepatitis type 1

A study comparing immunoblot assays and ELISA for detecting anti-F-actin antibodies in autoimmune hepatitis type 1 reveals comparable accuracy, with immunoblotting providing higher specificity. The findings suggest that immunoblot assays could be a reliable alternative to ELISA for diagnostic purposes, but larger studies are needed.
