Inflammation resulting from a viral infection has traditionally been thought to cause acute myocarditis, which can lead to fatal heart arrhythmias in otherwise healthy young adults. Now, a new study has shown for the first time that the virus itself damages heart cells before inflammation sets in, challenging traditional assumptions.Continue ReadingCategory: Medical, ScienceTags: Heart, Virus, Infections, Virginia Tech Inflammation resulting from a viral infection has traditionally been thought to cause acute…

Recent research by Dr. Nico Sollmann has uncovered objective evidence linking neck muscle inflammation to primary headaches, paving the way for more effective and targeted treatments for conditions like migraines and tension-type headaches.Researchers presenting at the annual meeting of the Radiological Society of North America (RSNA) have discovered objective evidence showing the involvement of neck muscles in primary headaches. This breakthrough could pave the way for more effective treatments.The distinct underlying…

Toxic strands of RNA known to cause cells to self-destruct have been found in both Alzheimer's and aging brains, suggesting a new approach to treating neurodegenerative diseases such as dementia.In a study based on mice and human brains led by Northwestern University in the US, researchers identified short lengths of RNA (ribonucleic acid) associated with DNA damage and cell death in relation to the disease and associated factors.They also found protective short RNA strands in the brain diminish with age, which could…

What was the last great year of Marvel dominance at the box office? Avengers: Endgame, the second-biggest-selling movie of all time, instantly springs to mind. Also that same year, both Captain Marvel and Spider-Man: Far From Home made $1.1 billion worldwide. That was 2019. And then came Disney Plus. Ever since then, things have been going from bad to worse for the superhero behemoth, culminating in a disastrous 2023 that saw the franchise crumble both critically and commercially, and the sequel to 2019’s Captain Marvel,…

Analysis of human brain tissue reveals differences in how immune cells behave in brains with Alzheimer's disease compared to healthy brains, indicating a potential new treatment target.University of Washington-led research, published in August, discovered microglia in the brains of people with Alzheimer's disease were in a pre-inflammatory state more frequently, making them less likely to be protective.Microglia are immune cells that help keep our brains healthy by clearing waste and preserving normal brain function.In…

Credit: Unsplash/CC0 Public Domain Methane is the second-most abundant greenhouse gas in Earth's atmosphere, and its emissions have been rapidly—and mysteriously—rising since 2007. Though pervasive, the origin of the colorless compound is tricky to trace, complicating efforts to curb gases that trap heat in the atmosphere and warm the planet. …

S. sputigena cells form a honeycomb-like structure that encapsulates S. mutans to greatly increase and concentrate acid production that boosts caries development and severity.

Folio 843 of Codex Atlanticus. Researchers from Politecnico di Milano discovered that black stains on the Codex Atlanticus’ passepartout were caused by metacinnabar, a black crystalline phase of mercury sulfide, due to a combination of restoration techniques, air pollution, and additives in the glue used during the restoration process.

South Korean researchers have discovered that reactive astrocytes, rather than amyloid-beta plaques, may be the main cause of Alzheimer’s disease. The team developed a new imaging technique using PET scans with radioactive acetate and glucose probes to visualize the interaction between astrocytes and neurons in Alzheimer’s patients. The researchers found that acetate, previously thought to be an energy source for astrocytes, can promote reactive astrogliosis and suppress neuronal metabolism. This breakthrough could lead…

Several teams of scientists believe they have uncovered the likely cause of a mysterious surge of severe hepatitis last year that hospitalized and killed children around the world. In threestudies published this week, the groups detail evidence that a common but usually not pathogenic virus was strongly associated with the cases, likely aided by co-infection with other common viruses. The affected children might have been genetically unlucky as well.Is AI Moving Too Fast? | Future TechEarly last year, health officials…
