Researchers just analyzed the health records of 2.56 million children — the largest study yet on MMR vaccine timing — and found no link to autism.

Scientists at the University of Washington used the Cosmos electronic health record database to track more than 2.5 million U.S. children with linked birth and parent data from January 2015 through December 2024, following each child until age 8 or their last recorded doctor's visit before the study ended.

The specific question wasn't just whether the MMR vaccine causes autism — a claim already contradicted by decades of prior research — but whether the timing of that first dose mattered. Some parents specifically worry that vaccinating closer to age 2 raises risk more than vaccinating earlier. The data found no such pattern: children who received their first MMR dose anywhere between 11.5 and 24 months showed no increased likelihood of an autism diagnosis compared to children vaccinated at other ages.

The study's design specifically worked around a common flaw in earlier vaccine-autism research. Observational studies on this topic are vulnerable to a specific kind of bias — children who see doctors more often, whether due to developmental concerns or general healthcare access, are simultaneously more likely to both get vaccinated on schedule and receive an autism diagnosis, which can create the illusion of a link where none exists. Accounting for that pattern is part of what makes this dataset's scale and design meaningful.

The findings arrive during a genuinely consequential year for measles in the U.S. — the CDC has recorded over 2,300 cases in 2026 alone, the highest count since 1991, with 93% of infections occurring in unvaccinated people.

The researchers describe the result plainly: the data reinforces existing evidence supporting the safety of MMR vaccination, adding one more large, carefully controlled dataset to a research base that has consistently failed to find the association many parents still fear.

For most of the 20th century, IQ scores rose steadily, generation after generation. A new study using nearly 400,000 Americans suggests that trend has quietly gone into reverse.

From the early 1930s onward, IQ scores rose consistently throughout the 20th century, increasing by roughly three to five points per decade — a well-documented phenomenon known as the Flynn effect. Researchers at Northwestern University set out to check whether that trend was still holding, analyzing survey responses from 394,378 Americans collected between 2006 and 2018 through the Synthetic Aperture Personality Assessment Project, a free online cognitive testing platform.

Three of the four cognitive domains tested showed a consistent downward trend across the study period: verbal reasoning (logic and vocabulary), matrix reasoning (visual problem-solving and analogies), and letter-and-number series (computational and mathematical reasoning) all declined. Only one domain moved in the opposite direction — spatial reasoning, measured through 3D rotation tasks, actually improved between 2011 and 2018.

The study didn't test why scores are dropping, though researchers note there's no shortage of competing theories — including changes in nutrition, general health, media consumption habits, and shifts in how children are educated. Elsewhere, researchers have proposed that the decline is tied to physiological markers like reaction time, which can't be practiced or gamed the way an abstract IQ test sometimes can — an argument used to counter the idea that this is just testing artifact rather than a genuine shift.

Northwestern researchers were careful to add an important caveat: a lower test score doesn't mean any individual person is "less intelligent" than someone who took the same test a decade earlier — it reflects a population-level shift, not a verdict on any one mind.

For decades, doctors considered the thymus a leftover organ that stops mattering once childhood ends. New research on 27,000 people says that assumption was wrong — and the difference in outcomes is enormous.

Researchers led by Harvard oncologist Hugo Aerts analyzed health data from more than 27,000 people across two separate long-term studies, the Framingham Heart Study and the National Lung Screening Trial. Participants in both studies had undergone CT scans that captured the size, shape, and composition of their thymus, which the team fed into a deep learning system trained to generate a "thymic health score" for each person — classifying them as having low, average, or high thymic health.

After adjusting for age, s*x, smoking, and existing health conditions, people with high thymic health had roughly a 50% lower relative risk of death within 12 years compared to those with low thymic health. They were also about 36% less likely to develop lung cancer, and about 50% less likely to die from it. Cardiovascular outcomes showed some of the largest gaps of all — a 63% lower risk of cardiovascular death in one cohort, and up to 92% lower risk in the other.

Aerts admitted the team expected the adult thymus might still matter to some degree, but said they didn't anticipate the differences being this strongly and consistently tied to longevity, cancer risk, cardiovascular disease, and even cancer therapy response across multiple independent datasets. A related study from the same team, published alongside this one, found that thymic health also predicted how well patients responded to immunotherapy across several cancer types, including lung cancer, melanoma, and breast cancer.

The researchers found smoking, obesity, and chronic inflammation were all linked to poorer thymic health, pointing to a two-way relationship: a healthier thymus appears to support better immune function, while inflammation and harmful habits can damage the organ in return, accelerating the shrinkage long assumed to be a harmless part of aging.

Stroke patients who rehabbed alongside a therapy dog worked significantly harder in every session — but walked out with the exact same recovery as everyone else.

Researchers at Mayo Clinic enrolled 50 stroke patients in Rochester, Minnesota and randomly split them into two groups. Both received standard physical, occupational, and speech therapy. One group also had a therapy dog woven directly into select sessions — patients brushed a dog's coat to rebuild hand strength, or walked a dog down the hall to practice mobility, working with one of 14 dog-and-handler teams from the hospital's Caring Canine Program.

The difference in effort was immediate and measurable. Therapists rated the dog group as significantly more engaged, and wrist monitors backed that up: those patients moved more each minute and stayed on their feet for about 90% of each session, compared to 81% in the group without a dog. Heart-rate variability data, a physiological marker of lower stress, also improved more over the course of dog-assisted sessions. One therapist's note captured it simply: a patient found visual scanning exercises easier with the dog present "because it was more fun."

None of that translated into a bigger recovery. By discharge, both groups had improved by roughly the same amount across quality of life, mobility, anxiety, and self-care. The honest explanation, researchers say, is dosage: dog sessions made up less than a tenth of each patient's full rehab schedule, spread across just six half-hour sessions over two weeks — likely too brief a window to shift a physical outcome that regular therapy already dominates.

The study was small, ran at a single hospital, and only tracked patients during their hospital stay, so no one has yet tested whether that extra motivation translates into better outcomes weeks or months later.

Still, the researchers argue engagement itself has real clinical value: a stroke patient who works harder and feels less stressed during rehab is a meaningful outcome on its own, even before it shows up on a final score.

Scientists testing compounds from a Brazilian tree against COVID-19 found something laboratory antivirals almost never manage: a substance that attacks the virus at two completely different stages of infection, at once.

Researchers at the University of São Paulo, led by pharmacist Jairo Kenupp Bastos, extracted galloylquinic acids (GQAs) from the leaves of Copaifera lucens, a tree native to Brazil's Atlantic Forest. The team had prior experience studying the broader Copaifera genus, which made this specific species a natural candidate to test.

The compounds attacked SARS-CoV-2 on two separate fronts simultaneously. They blocked the virus's spike protein, the key it uses to unlock and enter human cells, while also disrupting RdRp, the enzyme the virus depends on to copy its own genetic material once it's already inside. Most existing antivirals, including remdesivir and molnupiravir, only interfere with the RdRp side of that equation. In lab testing, the GQAs additionally showed direct virucidal activity, meaning they damaged viral particles on contact, independent of infecting a cell at all.

The efficacy numbers reinforce the finding: the compounds carried a selectivity index of 102, a ratio measuring how much more effectively a substance kills the virus compared to healthy human cells. A higher number signals a wider safety margin between an effective dose and a toxic one, and 102 is a genuinely strong result for an early-stage natural compound.

The work remains entirely preclinical, confined to lab dishes and computer modeling rather than animals or humans, and there's a long road between a promising lab result and an actual treatment.

Senator John Fetterman just said what millions of Americans are thinking: he's NOT going to play the Democrats' game of calling everyone a N*zi or a fascist. He's rejecting the far left's UNHINGED PLAYBOOK, and that's driving the progressive establishment absolutely crazy.

This is what real independence looks like. While radical Democrats demand lockstep conformity to their extreme ideology, Fetterman is actually thinking for himself. And you know what? The left can't STAND IT. They're already wheeling out primary challengers like Conor Lamb to punish him for the crime of using common sense.

Here's the truth: the Democrat Party has become so consumed by coastal elites and their radical agenda that they can't tolerate even ONE voice of moderation. Fetterman's willingness to reject their divisive rhetoric is a threat to their power structure. That tells you everything you need to know about where the Democratic Party really stands.

Real Americans are watching. And they're taking notes.

Young children are kind on instinct. Older kids are kind on purpose — and researchers just measured exactly when that shift happens.

Researchers at the University of Milan-Bicocca, the London School of Economics, the University of Stavanger, and Northwestern University studied 537 children between the ages of 3 and 10, randomly assigning each child to respond either under time pressure or after a delay across a series of social decision games, including sharing tasks, fairness games, and moral dilemmas.

Among the youngest children, snap decisions were significantly more prosocial than decisions made after time to think — the opposite of what most people would assume. Reflection, in early childhood, actually pulled kids toward less generous choices.

That pattern didn't hold. As children got older, the gap between their instant reactions and their considered choices steadily closed. By around age 9 or 10, children given time to reflect were just as kind and cooperative as those who answered instantly — deliberate reasoning had fully caught up to intuition.

Researchers describe this as a shift in the architecture of kindness itself, not merely its frequency: prosocial behavior starts out driven almost entirely by fast, automatic responses, then gradually becomes something children can also arrive at through conscious reasoning, layering deliberate values on top of an instinct that was there from the start. One consistent thread ran through every age group: the children's belief in how cooperative other people would be stayed the same throughout, regardless of age or how quickly they answered — only their own behavior changed as they grew.

The researchers are now using the same fast-versus-slow framework to study related questions, including whether young children have an intuitive tendency to obey authority, or whether that particular instinct is something children pick up later rather than starting with.

Milk tea has gained worldwide popularity in recent years (Wu, 2020). It refers to an umbrella term encompassing all beverages sold in milk tea shops, such as milk tea, fruit tea, floral tea, bubble tea, and others. This inclusive definition is based on the emerging trend of combining ‘milk tea + other tea drinks’ in the present Chinese milk tea market, gradually becoming mainstream (Shi et al., 2021; Zhao et al., 2021). ⁠
⁠
Previous research has investigated the relationship between the consumption of unhealthy diets, including milk tea, and poor mental health in 14,500 participants, revealing that milk tea consumption increased the risk of experiencing psychological symptoms (Xu et al., 2020). A more recent study specifically examined the link between milk tea consumption and mental health, finding a potential connection with an increased risk of depression and anxiety (Wu et al., 2022).⁠
