Do You Have A Sixth Sense? NIH Funds An Interoception Study To Find Out

Science 2.0 - Oct 14 2025 - 16:10
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.

Medicaid Emergency Room Costs For Illegal Immigrants Under $4 Billion In 2022

Science 2.0 - Oct 14 2025 - 13:10
A cross-sectional analysis of emergency Medicaid expenditures from data in the 2022 Medicaid Budget and Expenditure System found that of the 38 states plus Washington, DC, was nominal compared to overall spending.

There are confounders. Not all states allow it and 11 did not report emergency Medicaid spending on illegal immigrants and some, like California, now give health care for free to anyone regardless of their legal status, which means the $9 billion on emergency room care for illegal immigrants in 2024 is 70% due to that one state. Total Medicaid costs for illegal immigrants during 2021-2024 were $16 billion but this paper did not include other public spending.

How Will Humans And Machines Live Together?

Science 2.0 - Oct 12 2025 - 19:10

Everybody wonders what will happen with artificial intelligence (AI). Truly, it could go in any of several ways. This column lays out possible scenarios.

Scenario-building is usually a group activity, however. So I invite your views on the driving forces and possible additional scenarios.

Halloween Science: Your Ancestors May Have Eaten Mummies Because Of A Typo

Science 2.0 - Oct 12 2025 - 10:10

The next time someone tries to tell you ancient folk medicine was equivalent to modern science, remind them that people once consumed other humans as part of legal trade. Apothecaries sold powdered mummies, or at least what they claimed were powdered mummies, because of belief in medical cannibalism and that it cured everything from headaches to the plague.

Take that, antibiotics, your job could have been done by ground-up skulls.

The Evolution Of Halloween

Science 2.0 - Oct 11 2025 - 05:10

Samhain, All Hallows Evening. Hallowe'en, Halloween. The name has changed but the world’s fascination with a day of spooks and scares has never wavered. Except it has also always been about harvests and farming and food.

It may seem odd to lump together food and ghosts but that is Halloween in a cultural nutshell; a confusing mash-up of cultures and beliefs. That is actually a good thing. It is evidence for how creating melting pots of people who become one community is better than a salad bowl where no one wants to include outside groups in their customs.

Why Dogs Get Addicted To Their Lamb Chop Toy

Science 2.0 - Oct 10 2025 - 16:10
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.

Genetic Mutations In Brain Tumors Can Now Be Detected During Surgery

Science 2.0 - Oct 09 2025 - 15:10
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.

Science 2.0 - Oct 08 2025 - 07:10
With this post I would like to present a short update of my personal life to the few readers who are interested in that topic. You know, when I started writing online (over 20 years ago!), blogs used to contain a much more personal, sometimes introspective, description of the owner's private life and actions. Since long, they have been substituted by much more agile, quick-to-consume videos. But the old-fashioned bloggers who stuck with that medium continue to have a life - albeit certainly a less glamorous one than that of today's influencers; so some reporting of personal affairs is not out of place here.

Sperm MicroRNAs May Make Your Unwillingness To Exercise Inherited

Science 2.0 - Oct 06 2025 - 12:10
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.

UCLA: Asthma Sufferers Are Contributing To Climate Change

Science 2.0 - Oct 06 2025 - 12:10
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.

The Birth Paradox

Science 2.0 - Oct 02 2025 - 13:10

Surely you’ve noticed that many countries are subsidizing births – and others are banning abortions – even as tech lords lament the number of “useless people” in the world. You’ve noted the contradiction, and you’ve asked yourself, “What’s going on here?” Cool Hand Luke might say, “What we have here is a failure (of the two factions) to communicate.”

Zombies In Love And Other Scary Things Taxpayers Fund

Science 2.0 - Oct 01 2025 - 05:10
We definitely need to DOGE nonsense like acupuncture out of the NIH and use that money for science but I don't want to live in a culture where children's theater doesn't want to have a play about "the ups-and-downs of a lovesick zombie who can’t find a date inthe land of the living."

It may not sound all that kid-friendly but this was a children's theater in Oregon and a stroll down any street in Portland exposes children to a lot worse things than lonely zombies.

Doctors Urged To Proactively Address Cancer Myths - Groups Like American Cancer Society Won't

Science 2.0 - Sep 28 2025 - 11:09
Information freedom is a good thing but there is no question it has been weaponized. Many scientists have been ruined by activists and their trade groups who use Freedom of Information Act rules to find a sentence in correspondence with corporations or trade groups, remove it from context, and claim science is a corporate conspiracy. Then they publish it thanks to politically aligned schools like UC San Fransisco, where Tracey Woodruff, PhD, MPH, will help any attorney wanting to sue companies.

Deontological Decisions: Your Mother Tongue Never Leaves You

Science 2.0 - Sep 23 2025 - 09:09

Ιf you asked a multilingual friend which language they find more emotional, the answer would usually be their mother tongue – the one they used while growing up and probably still use at home. This does not mean they are incapable of expressing emotion in another language, but there is a clear link between first languages and stronger emotional expression.

This has a lot to do with where and how we learn a language. Our first language, which linguists call L1, is usually acquired in the emotionally charged settings of childhood and family. Second languages, known as L2, are often learned in more neutral contexts, such as schools and institutions, making them less emotionally intense.

How Synthetic Pumpkin Spice Took Fall Away From Organic Apples

Science 2.0 - Sep 22 2025 - 10:09
In 2003, the Human Genome Project was completed and both Tesla and LinkedIn were founded. Those were all interesting but not revolutionary; cars and job sites already existed, and we knew a lot about DNA, we just didn't have a complete "map" of a genome.

The biggest shift in culture was the introduction of the Pumpkin Spice Latte by Starbucks. In a few short years, it ended the dominance of apple cider to such an extent that unprompted people don't associate autumn with apple cider at all. Despite thousands of years of dominance as the Flavor of Fall.

How Elementary Particles Die

Science 2.0 - Sep 22 2025 - 07:09

A preamble

Subnuclear physics obeys the laws of quantum mechanics, which are quite a far cry from those of classical mechanics we are accustomed to. For that reason, one might be inclined to believe that analogies based on everyday life cannot come close to explaining the behavior of elementary particles. But that is not true – in fact, many properties of elementary particles are understandable in analogy with the behavior of classical systems, without the need to delve into the intricacies of the quantum world. And if you have been reading this blog for a while, you know what I think – the analogy is a powerful didactical instrument, and it is indeed at the very core of our learning processes.

Health and Human Services Secretary Robert F. Kennedy, Jr. is a former Natural Resources Defense Council lawyer and once such a pillar of the Democratic party that President Obama floated his name to run the Environmental Protection Agency.

Now he controls the agency that controls EPA. That is a big win for anti-science progressives. And because they are playing chess, not checkers, anti-science Republicans think it's their idea.
