Antipsychotic medications may be ineffective for treating or preventing delirium

Researchers analyzed data from 19 studies on hospitalized patients and found that antipsychotic medications did not reduce new cases of delirium. The study suggests that these medications may not affect the duration or severity of delirium, and more research is needed to understand their effectiveness in treating delirium.

Immunotherapy drug shrinks tumors in half of patients with rare, virus-linked skin cancer

In a clinical trial, half of 25 patients with Merkel cell carcinoma experienced substantial tumor shrinkage lasting nearly three times as long as conventional chemotherapy. Several patients had no remaining evidence of disease. The results suggest that immunotherapy drugs may be effective for other virus-associated cancers.

Thanks, actin, for the memories

Researchers at Rice University suggest that actin filaments play a key role in forming and storing long-term memories by stabilizing soluble cytoplasmic polyadenylation element binding proteins (CPEB) into longer, insoluble prion-like fibers. This process is thought to aggregate and encode memories in neurons' synaptic regions.
