Researchers have developed nasal drops that may help treat deadly brain cancer by boosting the immune response in the brain. The new method uses specially made tiny materials to deliver medication to the brain through the nose. This approach has shown promising results in mice with glioblastoma, a fast-growing brain cancer.
Key Facts
Scientists at Washington University and Northwestern University created the new nasal drop therapy.
The method uses small, engineered materials called spherical nucleic acids to deliver drugs to the brain.
In tests on mice, the nasal drops helped shrink glioblastoma tumors by activating the immune system.
Glioblastomas affect over 12,000 people each year in the U.S.
Current treatments for glioblastoma include surgery, radiotherapy, and chemotherapy, but there is no cure.
The nasal drops are not yet ready for human use, and further development is needed.
The approach targets a cell pathway called STING, which helps activate the immune system.
This method could provide a non-invasive treatment option, avoiding the need for direct tumor injection.

Researchers at the University of Reading in England are exploring how mRNA technology used in COVID vaccines might help reduce muscle damage in snakebite victims. The study showed that this technology could protect muscles from damage caused by venom from the terciopelo snake found in Central and South America. This approach might lead to new treatments that lower the risk of permanent disabilities from snakebites.
Key Facts
mRNA technology, used in COVID vaccines, might also reduce muscle damage from snakebites.
The University of Reading tested this on venom from the terciopelo snake, common in Central and South America.
The treatment uses mRNA to produce antibodies that protect against venom-induced muscle damage.
In lab tests, the treatment reduced damage in human muscle cells within 12-24 hours of injection.
In mice, the treatment provided protection against muscle injury 48 hours before venom exposure.
Current antivenoms mainly target toxins in the bloodstream, often missing muscle tissue damage.
Researchers aim to expand this method to target multiple venom toxins.
Challenges include the time needed for antibody development and storage issues in remote locations.
