Intermittent fasting, and fasting in general, has been a popular fad health gimmick, but the science isn't on its side. Instead, proponents believe mice are little people so if mice weaned on starvation diets lived longer, people would also.
The older you get, the more frail you become. The more frail you become, the greater the risk of falling, hospitalization, and shorter life expectancy.Doctors talk about physical activity to reduce frailty but less attention is paid to biology. A new paper suggests that the hypothalamic–pituitary–gonadal (HPG) axis, the body’s system of regulating production of the hormone testosterone, can impact frailty."Suggests" means this is only EXPLORATORY, not human science, but a relationship between
Actors, artists, and musicians are rightly worried about the impact of AI on their incomes but doctors and scientists welcome the help. They know typewriters didn't make literature worse than writing in longhand and "AI" - LLMs - likewise removes the 'how' of information access so thinkers can get to the 'why.'In modern government-controlled healthcare, doctors are more pressed for time per patient than ever. Often while relying on incomplete information. Electronic health records contain vast amounts of patient data but much of it remains difficult to interpret quickly, and that is even more challenging for patients with rare diseases or unusual symptoms.
When you picture a black hole, you probably picture in the center of a galaxy with matter swirling toward it. You're not wrong but that is why the exception proves the rule.A recent study detected a surprising tidal disruption event where a black hole outside the center of a galaxy is tearing apart a star. Even stranger and defiance of black hole lore, the delayed and powerful radio outbursts suggest previously unknown processes in how black holes eject material over time. Designated AT 2024tvd, it is to-date the fastest-evolving radio emission ever observed from a black-hole-driven stellar disruption.
The process by which the nervous system continuously receives and interprets the body’s physiological signals to keep vital functions running smoothly, a "sixth sense" called
interoception
that tells your brain when you need to breathe, when your blood pressure declines or when you have an infection, is getting some star power; a Nobel laureate neuroscientist.And an NIH grant.
In 1956, prize-winning puppeteer Shari Lewis appeared on the Captain Kangaroo children's show and debuted a new...well, it was basically a sock with eyes.(1) She called it Lamb Chop, though, and her ventriloquism was a big hit with kids.Imagine what she would think if she knew Lamb Chop toys were a big hit with dogs.It's a science mystery why, but dogs love them. Dogs who like to cuddle are obsessed with it, as are dogs who want to destroy things. They like the squeaks, the softs, and perhaps that it almost resembles an animal. Dogs get obsessive-compulsive a lot, according to a new paper.
Conventional genetic analysis methods for genotyping of brain tumors usually require one or two days to obtain results but a new method can determine optimal resection margins during surgery in just a few minutes.The ability to accurately detect genetic mutations in a brain tumor was demonstrated with isocitrate dehydrogenase (IDH) and telomerase reverse transcriptase (TERT) promoters, which are markers for diagnosis of diffuse glioma—the most common type of brain tumor. Their system uses a
Polymerase Chain Reaction device in combination with their own protocol and it enables DNA extraction using only heat incubation.
A recent study found the first evidence that sperm microRNAs act as carriers of epigenetic information, enabling the intergenerational transmission of paternal exercise capacity and metabolic health, thereby exerting profound effects on offspring development.The bad news if you want an excuse for your poor fitness is this is epigenetics and only in mice, which means it is only EXPLORATORY. Mice are not little people and epigenetics lacks the same biological foundation as actual evolution and genetics.
A new cross-sectional analysis estimates that asthma inhalers contribute the same carbon emissions as 530,000 cars each year. That's over over 2 million metric tons of greenhouse gases annually from the three types of inhalers approved for asthma or COPD during the years 2014 to 2024.
Three years into war with Russia and martial law, public services continue to operate and citizens continue to have confidence in them. A new analysis of survey results in Government information Quarterly says trust in public figures and a sense of cooperation are key factors.
New survey results find that sociocultural factors may be involved in how likely someone is to report moderate to severe depression symptoms and get a prenatal depression diagnosis.
FDA-approved flu treatments target viral enzymes of influenza but the virus mutates, which is why there is a new vaccine each year. Recent work showed that a cocktail of antibodies offered protection mice from nearly every strain of influenza. Even avian and swine flu. Their cocktail did not allow viral escape, even after a month of repeated exposure.
People in the northeast of the United States think they have greater "wellness" than everywhere else except California. People in the southern United States think they have more wellness than everywhere else.Which is right? They both are. Wellness may be in social media ad campaigns and have diets and apps and fads under the umbrella, but it's entirely subjective. The northeast believe they have greater wealth and social standing, which they consider traditional wellness. The south sense of purpose and community identity, which is existential wellness.
