Researchers have identified a critical biological difference in how glioblastoma develops in male and female laboratory models, pinpointing an immune pathway that fuels tumor growth only in females. The study shows that the neurotransmitter GABA boosts the cancer-protecting activity of immune cells in female models—but not male models—and that blocking that signal improved outcomes. The findings could one day lead to new drug targets and therapeutics specifically for women. The paper is published in the journal Nature Cancer.
Men and women experience many diseases very differently. Certain diseases present more commonly in one sex than in the other, some conditions may cause different symptoms in men and women, and some treatments work better—or not at all—for one sex over the other.
Cancer is no exception. There are major differences in male and female immune systems, and this system is critical both for cancer growth and for successfully becoming cancer-free. For example, some immunotherapies work better in men than in women, and vice versa.
Tecedor et al. used directed evolution to engineer AAVs with enhanced ependymal and brain delivery after injection into the cerebrospinal fluid. I think it would be interesting to try lumbar puncture delivery of these AAVs as well to see if they maintain decent biodistribution. (See my other post about Hinderer et al.’s paper: https://doi.org/10.1016/j.omtm.2020.04.012).
AAV capsid variants enriched for transduction of ventricular lining cells and brain parenchyma reduce the dose required for gene therapy to the CNS.
Wow, this is an interesting turn of events: Janelia launching a 10-year $1B effort to study the Danionella fish as a model organism for understanding the nervous system. (Note: this is different from zebrafish). I’m intrigued by the direction, but I also feel for those researchers at Janelia who had the rug pulled out from under them. It’s a tricky situation.
The Janelia Research Campus is launching two new projects: whole-brain imaging of a transparent fish called Danionella and an “AI-in-the-loop” tool to help parse all the imaging data, the facility announced last week.
As part of the change, Janelia is also shuttering two programs and plans to phase out projects that use rodent models, The Transmitter has learned. Janelia is funded by the Howard Hughes Medical Institute (HHMI), a private nonprofit biomedical research institution.
Investigators who run rodent labs have roughly three years to wrap up their projects and find new positions, and Janelia plans to provide each researcher with an additional $1 million in transition funding, says Gerald Rubin, head of biology and senior group leader at Janelia. The move does not affect external research funded by the HHMI, including the HHMI Investigators and Hanna H. Gray Fellows programs, Rubin adds.
Biology has clever ways to mask the effects of potentially harmful gene mutations. Scientists are investigating how this ‘buffering’ works — and how to exploit it.

Michael Levin is a developmental and synthetic biologist at Tufts University whose work sits at the intersection of biology, bioelectricity, artificial life, regenerative medicine, synthetic biology, computer science, cognitive science, and philosophy of mind. He is known for his research on how cells communicate, make decisions, build bodies, repair tissues, and form collective intelligence through bioelectric signals. His work on Xenobots and Anthrobots has opened new questions about living robots, synthetic life forms, biological machines, morphogenesis, basal cognition, cellular intelligence, regeneration, cancer, aging, and the nature of mind beyond the brain.
In this conversation, Michael Levin and I explore whether mind and intelligence are binary or exist on a continuum, why cognition may be much older than brains, and how systems from cells to humans can pursue goals in different ways. We discuss the TAME framework, the spectrum of persuadability, cognitive light cones, bioelectricity, gap junctions, multicellular intelligence, Xenobots, Anthrobots, kinematic self-replication, neural wound healing, emergence, physicalism, mathematics, Platonic space, algorithms, bubble sort, Turing machines, evolution, human creativity, artificial intelligence, regenerative medicine, and the future of biology. This episode is for anyone interested in philosophy, consciousness, mind, intelligence, synthetic biology, developmental biology, AI, complex systems, evolution, and the deeper question of what it means for matter to become alive, intelligent, or aware.

A clinical trial is exploring whether high doses of vitamin B3 could give patients with glioblastoma a better chance against the aggressive brain cancer. Scientists found that niacin may help revive immune cells that tumors shut down, allowing them to attack cancer more effectively. Early results have been promising, with patients showing significantly better progression-free survival than expected.
Two cups of warm water don’t make one cup of boiling water. But in the quantum world, multiple low-energy photons can combine to produce a single, higher-energy photon.
A research team at Kyushu University has developed a solid-state molecular material that “upgrades” visible light into ultraviolet (UV) light under ordinary outdoor sunlight, achieving a conversion efficiency of 1.9%. The study is published in Nature Communications.
Harsh UV light is something most people try to avoid in summer, yet it is indispensable in fields ranging from air purification and resin curing in 3D printing to gel hardening in dental fillings and nail art. Despite its importance, UV accounts for only about 6% of the sunlight reaching Earth’s surface, with only a fraction of that being practically usable.
A groundbreaking study reveals that OLE, a newly discovered molecule, can restore the protective functions of brain immune cells in Alzheimer’s disease, reducing toxic plaque accumulation and enhancing memory. This research could pave the way for new therapeutic approaches to combat Alzheimer’s.
