Lab-Designed Peptide Targets Glioblastoma Stem Cells

A newly developed lab-designed molecule, JM2, may offer a promising therapy to combat glioblastoma recurrence by targeting the tumor’s most resilient cells. Researchers discovered that glioblastoma stem cells rely on the protein connexin 43’s interaction with microtubules—an interaction disrupted by JM2.

Future Thinking Training Reduces Impulsivity

A new study finds that training people to think about specific future events can reduce impulsivity and improve decision-making. Researchers used fMRI scans to show that practicing episodic future thinking increased connectivity in key brain regions, making participants less likely to choose immediate rewards over long-term benefits.

Mitochondria’s Role in Social Memory May Offer Clues to Brain Disorder

Researchers have identified a unique mitochondrial process in CA2 neurons that supports learning, memory, and social recognition. Mitochondria in different parts of these neurons vary in structure and function, with those at the outermost synapses relying on the mitochondrial calcium uniporter (MCU) for plasticity. Deleting the MCU gene disrupted this plasticity, highlighting its crucial role in maintaining neural connectivity.

Glioblastoma Drug Resistance Pathway Identified

Researchers identified a key signaling pathway, PI3K-beta, responsible for chemotherapy resistance in glioblastoma. Blocking this pathway makes tumor cells more sensitive to temozolomide, a standard chemotherapy drug. This discovery offers a potential new approach to treating glioblastoma, a deadly brain cancer, by overcoming drug resistance and improving patient outcomes.

Serotonin and Dopamine Play Key Role in Social Decisions

A new study unveiled the intricate role of dopamine and serotonin in social decision-making, using Parkinson's disease patients as subjects. Through the "ultimatum game," the team discovered that people's choices vary significantly when interacting with humans versus computers, influenced by the dynamic interplay between these neuromodulators.
