Repurposed NHS Cancer Therapies and Solar Corona Mysteries
London researchers discover glaucoma drops block cancer metastasis, while high-resolution solar imagery solves a 50-year atmospheric heating puzzle.
Science
ICR London identified how NHS glaucoma drugs block cancer metastasis — opening a fast path to clinical trials using safe, existing medicines.
BackgroundMetastasis — the spread of cancer cells from primary tumors to other organs — accounts for the vast majority of cancer deaths worldwide. Drug repurposing accelerates clinical trial timelines because safety profiles for approved medications are already established.
- Rho kinase (ROCK) inhibitors are currently prescribed on the NHS to treat glaucoma by relaxing eye tissue mesh.
- Aggressive breast, melanoma, and leukemia cells rely on ROCK enzymes to squeeze through physical tissue barriers, making them vulnerable to inhibition.
- The findings published in iScience clear the path for clinical trials converting eye drops into anti-metastatic treatments, potentially shortening drug development by years.

A new low-temperature chemical method turns toxic PVC waste into premium jet engine lubricant — offering a practical solution for unrecyclable plastic.
BackgroundPolyvinyl chloride (PVC) is widely used in construction materials but presents extreme recycling challenges due to toxic chlorine content. Most discarded PVC ends up in landfill or incineration plants, releasing toxic chemical byproducts into the environment.
- The reaction utilizes aluminum trichloride and alpha-olefins at a low operating temperature of 70°C, drastically lowering energy costs compared to traditional incineration.
- The resulting synthetic fluids match commercial quality standards required for high-stress aerospace machinery, creating a viable commercial market for legacy plastic waste.
- The breakthrough published in Nature offers an industrial pathway to turn toxic plastic waste into high-value chemicals, diverting thousands of tonnes from UK and European landfills.

High-resolution solar images exposed magnetic field braiding on the Sun — resolving why its outer atmosphere burns millions of degrees hotter than its surface.
BackgroundAstronomers have struggled to explain why the Sun's outer corona reaches temperatures over 1,000,000°C while its surface remains relatively cool at 6,000°C. High-resolution solar telescopes capture fine magnetic turbulence across the solar atmosphere.
- Observations confirmed Kelvin-Helmholtz Instabilities occurring within surface plasma vortices for the first time, giving astrophysicists direct observational proof of energy transfer.
- Twisted magnetic field lines trigger explosive coronal mass ejections that disrupt satellite communications on Earth, threatening GPS and electrical grid stability.
- The research published in Nature provides foundational physics for predicting severe space weather events, helping operators safeguard orbital infrastructure before solar storms hit.

A SpaceX rocket stage slamming into the Moon highlights the lack of binding rules governing cis-lunar space debris.
BackgroundDiscarded rocket stages left in high-Earth or cis-lunar orbits can remain untracked for years before gravitational pulls trigger accidental collisions. International space agencies lack binding legal frameworks governing space debris deposition on the lunar surface.
- The booster stage had drifted in space since deploying lunar lander payloads in January 2025, gradually pulled off course by gravitational forces.
- Observatories in Hawaii and South America detected an artificial gas cloud lasting 10 minutes post-impact, providing rare observational data on lunar soil composition.
- Scientists warned that uncoordinated lunar impacts risk contaminating scientific sites and future mission landing zones, accelerating calls for international orbit management rules.
