So, what happened during September 2025?
In world news:
September 5th – Chemists at the University of Copenhagen made a new material called BAETA from old plastic bottles. It can catch CO2 from the air. Making BAETA does not need much energy and it can be made a scale (Click here and here to read more about this).
September 8th – Elusive street artist Banksy unveiled a mural on London’s Royal Courts of Justice, depicting a judge attacking a pro-Palestine protester with a gavel. The artwork was quickly covered up by large sheets of plastic and metal barriers, and court officials said the work would be removed (Click here to read more about this).
September 9th – Protesters set fire to Nepal’s parliament building in Kathmandu as “Generation Z” protests against Government corruption and social media bans escalated (Click here to read more about this).
September 9th – University of Florida researchers develop a chip that replaces electricity with light for key AI tasks.

In the world of Parkinson’s research, a great deal of new research and news was reported:
In September 2025, there were 1,101 research articles added to the Pubmed website with the tag word “Parkinson’s” attached (9,812 for all of 2025 so far). In addition, there was a wave to news reports regarding various other bits of Parkinson’s research activity (clinical trials, etc).
The top 5 pieces of Parkinson’s news
1. Air pollution – may not be such a “hoax”:
An analysis of >56M US Medicare beneficiaries revealed that chronic PM2.5 exposure was significantly associated with first hospitalizations for α-synucleinopathies. The investigators found that the link was stronger for Lewy body dementia patients compared to Parkinson’s without dementia (Click here to read more about this and click here to read an editorial on this research).
2. The DNA damage data:
Using longitudinal analysis of PPMI blood samples, researchers investigated DNA damage in Parkinson’s and found disrupted DNA repair pathways. They observed a biased suppression of longer transcripts, indicating age-related, transcription-stalling DNA damage. At baseline, DNA damage was only detected in patients with more severe progression of motor symptoms over 3 years (potential predictor of disease severity biomarker?). These results were validated in independent Parkinson’s cohorts. Increased DNA damage was also observed in postmortem nigral dopamine neurons in PD cases (Click here to read more about this).
3. First BlueRocker in for Phase 3:
Bluerock Therapeutics announced that the first participants has been treated in their randomized, sham surgery-controlled, double-blind Phase 3 “exPDite-2” trial of the investigational cell therapy bemdaneprocel for Parkinson’s (Click here to read more about this).
4. Hope for Huntington’s:

5. Phase 2 results for AlzProtect:
