I’m convinced a lot of diseases, MS, parkinsons, alzheimers, most cancers, are the result of bacterial or viral infections.

Building on a growing body of evidence linking viral infections with neurodegenerative disease, a new study published in Nature Communications has demonstrated how certain molecules on the surfaces of viruses can promote the aggregation of toxic proteins associated with diseases such as Alzheimer’s and Parkinson’s.

The idea that microbial infections can trigger neurodegenerative disease is not new. As far back as the 1950s scientists have been postulating ways an acute viral infection can lead to progressive neurological problems years, or even decades, later.

While evidence for this association is certainly growing, the mechanisms by which viral threats can influence the progression of brain diseases are still resolutely hypothetical. A common hypothesis speculates some viral infections may trigger abnormal immune responses that subsequently linger for years, ultimately generating neurological damage associated with some brain diseases.

I am pleased to share our most recent video on the “Dementia Safety Study” funded by Maximum Life Foundation and run by IHS, in which BioViva did the data analysis. This treatment shows promise for the millions of people who have dementia today. Though not a cure, it is a step in the right direction.

Can gene therapy delay or reverse Alzheimer’s and other dementias?

The strategy outlines how AI can be applied to defence and security in a protected and ethical way. As such, it sets standards of responsible use of AI technologies, in accordance with international law and NATO’s values. It also addresses the threats posed by the use of AI by adversaries and how to establish trusted cooperation with the innovation community on AI.

Artificial Intelligence is one of the seven technological areas which NATO Allies have prioritized for their relevance to defence and security. These include quantum-enabled technologies, data and computing, autonomy, biotechnology and human enhancements, hypersonic technologies, and space. Of all these dual-use technologies, Artificial Intelligence is known to be the most pervasive, especially when combined with others like big data, autonomy, or biotechnology. To address this complex challenge, NATO Defence Ministers also approved NATO’s first policy on data exploitation.

Individual strategies will be developed for all priority areas, following the same ethical approach as that adopted for Artificial Intelligence.

Taking psilocybin can affect one’s emotional state when listening to music, according to new research presented earlier this month at the 34th ECNP Congress in Lisbon.

Psilocybin, the active psychedelic component of magic mushrooms, has previously shown great promise when used in therapy settings for the treatment of depression. Many of these clinical trials often make use of selected music playlists to support the subjective psychedelic experience felt by the trial participant.

Now, scientists believe that this action of combining psilocybin with music may result in enhanced emotional processing on behalf of the participant, implying that music should be treated as a more active component of psilocybin therapy.

Collaboration, transparency & urgency for rare disease research — mike graglia, managing director & co-founder, syngap research fund — SRF.

Mike Graglia is the Managing Director & Co-Founder of the SynGAP Research Fund (SRF — https://www.syngapresearchfund.org/), an organization that he set up in 2018 with his wife Ashley, after their son was diagnosed with a rare neurological disease caused by an insufficiency in SynGAP protein, which causes the life-changing diagnoses of Epilepsy, Autism, sleep disorder and intellectual disability.

The mission of SRF is to improve the quality of life of SynGAP1 patients through the research and development of treatments, therapies and support systems.

Here we report a rapid Scalable and Portable Testing (SPOT) system consisting of a rapid, highly sensitive, and accurate assay and a battery-powered portable device for COVID-19 diagnosis. This device consists of 3D printed casing and internal structure with precise temperature control and fluorescence detection, whereas this assay combines RT-LAMP with an Argonaute protein from hyperthermophilic archaeon Pyrococcus furiosus (PfAgo) capable of precise recognition and cleavage of a target DNA at 95 °C as directed by small 5′-phosphorylated single strand DNA (ssDNA) as guide DNA (gDNA)10,11. Due to the multi-turnover activity of PfAgo, its secondary cleavage mechanism can be harnessed for specific, sensitive, and multiplex nucleic acid detection12,13. For COVID-19 samples, although nasopharyngeal swab and nasal swab samples were recommended for detection of SARS-CoV-2, saliva samples are a more attractive alternative due to the ease, safety, and non-invasive nature of its collection14,15, and its relatively high viral load during the first week of infection16. These benefits enable a saliva sample to be an ideal specimen for reliable and rapid self-detection without professional supervision17,18,19. While current CRISPR-based detection systems normally require 50 min for testing, PfAgo can dramatically speed up the detection process by requiring only 3–5 min for cleavage of amplified products, thereby shortening the total turnaround time for testing to less than 30 min. Moreover, successful PfAgo detection requires at least two sequence-specific cleavages, endowing the SPOT system with high specificity and the ability for multiplexing. Finally, to validate the SPOT system, the sensitivity and accuracy of the SPOT system were determined by using 104 clinical saliva samples.

- please note: The SPOT system also may be useful for detecting genetic markers of certain types of cancer in saliva.

There is a clear need for rapid, accurate and scalable Covid-19 diagnostics. Here the authors use PfAgo to detect viral sequences amplified by RT-LAMP in a handheld battery-powered device.

Protein intake is known to be vital for maintaining brain function in older individuals. Now, using a mouse model of Alzheimer’s disease, researchers have shown that the intake of a specific set of amino acids can inhibit the death of brain cells, protect the connections between them, and reduce inflammation, preserving brain function. Their research suggests that this amino acid combination called Amino LP7 can hinder the development of dementia, including Alzheimer’s disease.

When the COVID-19 pandemic shut down experiments at the Department of Energy’s SLAC National Accelerator Laboratory early last year, Shambhu Ghimire’s research group was forced to find another way to study an intriguing research target: quantum materials known as topological insulators, or TIs, which conduct electric current on their surfaces but not through their interiors.

Denitsa Baykusheva, a Swiss National Science Foundation Fellow, had joined his group at the Stanford PULSE Institute two years earlier with the goal of finding a way to generate high harmonic generation, or HHG, in these materials as a tool for probing their behavior. In HHG, shining through a material shifts to higher energies and higher frequencies, called harmonics, much like pressing on a guitar string produces higher notes. If this could be done in TIs, which are promising building blocks for technologies like spintronics, quantum sensing and quantum computing, it would give scientists a new tool for investigating these and other quantum materials.

With the experiment shut down midway, she and her colleagues turned to theory and computer simulations to come up with a new recipe for generating HHG in topological insulators. The results suggested that circularly polarized light, which spirals along the direction of the laser beam, would produce clear, unique signals from both the conductive surfaces and the interior of the TI they were studying, bismuth selenide—and would in fact enhance the signal coming from the surfaces.
