“Don’t take Tylenol. Don’t take it.” President Trump sent a clear message to Americans last year when he said pregnant people should avoid acetaminophen, the active ingredient in Tylenol. She said taking painkillers increased the risk of having an autistic child, although the scientific consensus found no link and untreated fever carries its own risks for the neurodevelopment of pregnant women and their fetuses. The president and health leaders also pledged to increase access to leucovorin, a little-known cancer drug that helps some people with autism. A new study says early data shows the Trump administration’s messaging worked. In the…

Long-term use of stimulants for attention-deficit/hyperactivity disorder (ADHD) does not appear to cause lasting changes in brain development, according to a study published in . Advances in neuropsychopharmacology and biological psychiatry. Medications such as methylphenidate, commonly known as Ritalin, are widely prescribed to treat ADHD. This condition is characterized by a persistent pattern of inattention, hyperactivity, and impulsivity. Stimulants work by increasing levels of brain chemicals, particularly dopamine and noradrenaline, which help regulate attention and behavior. Although these drugs are considered highly effective in the short term, scientists have long debated whether taking these drugs during childhood, when the brain…

Scientists at the Indian Institute of Technology Gandhinagar (IITGN), working with international collaborators, have discovered that ocean temperature patterns play a key role in limiting the extent to which droughts spread around the world. Their findings are: Communication Earth and Environmentbased on climate records spanning 1901 to 2020. Analysis shows that synchronous droughts typically affect only 1.8% to 6.5% of Earth’s land at a time. This is much lower than previous suggestions that up to one-sixth of the planet could experience drought at the same time. The researchers investigated how droughts begin in different parts of the world and whether…

A study of individuals who reported heavy alcohol and cannabis use found that individuals with average and high working memory tended to have significantly lower urges to drink after smoking cannabis containing 7.2% THC compared to a placebo. This effect was not seen when the THC concentration in cannabis was 3.1%. Decreased working memory capacity was associated with an overall stronger urge to drink alcohol. This study addictive behavior. Alcohol use disorder is a medical condition characterized by problematic patterns of alcohol use that cause significant impairment and distress. This includes symptoms such as difficulty controlling drinking, strong cravings for…

For years, paleontologists have studied the growth rings preserved in fossilized foot bones. tyrannosaurus rex. Like the growth rings inside a tree trunk, these marks help scientists estimate how old the dinosaurs were when they died and how fast they grew. Previous research suggested that tyrannosaurus It reached its full size by about age 25. A new, more comprehensive analysis challenges this schedule. Researchers examined 17 Tyrannosaurus specimens ranging from young juveniles to gigantic adults and determined that the famous predator likely continued to grow for about 40 years until it reached a maximum weight of around 8 tonnes. Research…

Research from the University of Limerick in Ireland reveals hidden challenges for women living with and managing gestational diabetes mellitus (GDM). The study, led by academics from UL’s School of Psychology, is the first to consider the evidence in this area. Particular emphasis is placed on how partners influence the experiences of women diagnosed with GDM. The study, which analyzed the experiences of nearly 2,000 women in 21 countries, found that while partners play an important role in women’s experiences of GDM, support is not always helpful and the level of support provided varies widely. An extensive review entitled ‘Partners…

The brain relies on a real-time supply of oxygen and nutrients through the microvasculature, which runs like electrical wires through nerve tissue. Modern imaging techniques allow researchers to track the activity of individual neurons in the brain, but they have not yet advanced enough to dissect microvascular function at comparable spatial scales. This gap impedes our understanding of cerebral small vessel disease and its contribution to cognitive impairment and dementia. To address this challenge, a research team at Washington University in St. Louis and Northwestern University, led by Song Hu, professor of biomedical engineering in the McKelvey School of Engineering,…

This study is one of the first to examine strengths-based indicators of well-being in a large population-level Indigenous sample. Healthy functioning was significantly associated with not smoking, being physically active, having fewer chronic health conditions, and meeting basic financial needs. These results challenge deficit-centered discourses that blame individuals and groups rather than policies, socio-economic conditions, or other structural issues. Rather, it emphasizes the value of identifying the factors that support the flourishing of indigenous communities. Understanding Indigenous health requires recognizing both the structural barriers created by colonization and the remarkable strengths that our communities continue to embody. Our findings…

New research published in Journal of Consumer Psychology suggests that a person’s political leanings influence how they view the environmental benefits of their own sustainable choices. This study provides evidence that conservatives tend to view behaviors such as recycling and eating a plant-based diet as having less positive impact than liberals, predicting lower engagement in these behaviors. These differences appear to be due to how common these behaviors are perceived to be within an individual’s social circle. The authors of the new study wanted to understand why conservatives generally engage in less environmentally friendly behavior than liberals. Previous explanations have…

Accumulation of the protein tau in the brain is one of the hallmarks of Alzheimer’s disease. In a paper published March 5 in the journal Cell Press. Cell Press Blueresearchers report a previously unknown mechanism that appears to allow tau accumulation. The study, which used patient tissue as well as animal and cell models, suggests an important role for specialized brain cells, tanycytes, in regulating brain-to-body signaling. Our findings reveal a previously underappreciated, disease-relevant role for tanycytes in neurodegeneration. Focusing on tanycyte health may be a way to improve tau clearance and limit disease progression. ” Vincent…
