Compared to other forms of prevention, a unique issue for pandemic preparedness is that it is forever unclear what pathogen, exactly, the world needs to be prepared for. There are an estimated 300,000 viruses that infect mammals; add in birds, and the estimate grows to more than half a million. Some of those viruses are much greater threats than others.

Researchers have developed a new compound that can prevent long COVID symptoms in mice that could lead to a future drug for the debilitating condition in humans. Developed by researchers at the Walter and Eliza Hall Institute of Medical Research (WEHI) in Melbourne, the world-first study found mice treated with the antiviral compound were protected from long-term brain and lung dysfunction, which are key symptoms of long COVID.

Researchers from Pretzel Therapeutics Inc. and the University of Gothenburg have published new insights on how mutations in the POLG gene affect its functionality and are tied to PolG diseases. They have also presented a compound for its potential treatment, PZL-A. They published their results in Nature on April 9, 2025.

Scientists from the Machine Intelligence from Cortical Networks (MICRONS) consortium have published the microconnectome of a cubic millimeter of the mouse brain. This is the most complete map of this organ to date at nanometer resolution for a mammal. It not only contains the structure and connections of each and every cell in that volume of tissue, but is also linked to the neuronal activity of that portion of the CNS, linking anatomy and function in the same cells.

The current treatment strategies for neurodegenerative diseases focus on targeting Aβ in Alzheimer’s disease (AD), α-synuclein aggregates in Parkinson’s disease (PD) and anti-tau therapies, which are primarily used in AD but are also being explored for PD. At the 2025 International Conference of Alzheimer’s & Parkinson’s Disease and Related Neurological Disorders, Aditya Iyer, senior RD scientist from Amyl Therapeutics Srl, presented data on an option which could potentially serve as a pan-amyloid therapeutic.

“The nation’s scientific enterprise is being decimated.” That statement in an open letter “to the American people” signed by 1,800 members of the U.S. National Academies, is made concrete in a list of 709 NIH grants – and counting – that have been axed since President Donald Trump was inaugurated on Jan. 20.

Neurodegenerative pathologies, once primarily associated with protein alterations, should be revisited in the context of lipidopathies, researchers argued at the 2025 International Conference of Alzheimer’s & Parkinson’s Disease and Related Neurological Disorders (AD/PD 2025).
