A study found that Streptococcus anginosus, a common mouth and gut bacterium, is more prevalent in stroke patients and linked to higher stroke risk and mortality. Streptococcus anginosus, a bacterium commonly found in the mouth and gastrointestinal tract, may be present in high levels in the gut.
For their study published in the journal Nature Medicine, the group generated thousands of articles containing misinformation and inserted them into an AI training dataset and conducted general LLM queries to see how often the misinformation appeared.
Prior research and anecdotal evidence have shown that the answers given by LLMs such as ChatGPT are not always correct and, in fact, are sometimes wildly off-base. Prior research has also shown that misinformation planted intentionally on well-known internet sites can show up in generalized chatbot queries. In this new study, the research team wanted to know how easy or difficult it might be for malignant actors to poison LLM responses.
Light therapy is emerging as a promising, non-pharmacological treatment for Alzheimer’s.
Alzheimer’s disease is a progressive neurological disorder that primarily affects older adults, leading to memory loss, cognitive decline, and behavioral changes. It is the most common cause of dementia. The disease is characterized by the buildup of amyloid plaques and tau tangles in the brain, which disrupt cell function and communication. There is currently no cure, and treatments focus on managing symptoms and improving quality of life.
Caltech just manufactured a wearable sweat sensor that “inkjet prints” biomarkers to better monitor the human body.
Using light-sensitive drugs, they identified a promising neural pathway that could lead to more effective, safer anxiety treatments.
Targeting Anxiety with Brain Circuit Research
Researchers at Weill Cornell Medicine have identified a specific brain circuit that, when inhibited, reduces anxiety without causing noticeable side effects — at least in preclinical models. Their findings highlight a potential new target for treating anxiety disorders and introduce a broader strategy for studying drug effects in the brain using a technique called photopharmacology.
CINCINNATI (WKRC) — Researchers believe they discovered a new type of life form living in the human body that were previously misidentified as viruses.
According to a new study from bioRxiv that has yet to be peer reviewed, researchers identified a new type of life form in the human body, which they called “Obelisks,” that appeared similar to viruses but with multiple key differences that make them a different type of organism.
For starters, the Obelisks do not match any previously recognized virus, so if they are viruses they are brand new. The researchers said that it’s highly unlikely the Obelisks are viruses, since they identified over 30,000 different variants, and they would have expected to find a match for a previously identified virus among so many variations.
