Archaeologists have collected data which indicates the presence of a large-scale pre-Columbian fish-trapping facility. Discovered in the Crooked Tree Wildlife Sanctuary (CTWS), the largest inland wetland in Belize, the team dated the construction of these fisheries to the Late Archaic period (cal. 2000-1900 BCE), pre-dating Amazonian examples by a thousand years or more.

While it's well known that sleep enhances cognitive performance, the underlying neural mechanisms, particularly those related to nonrapid eye movement (NREM) sleep, remain largely unexplored. A new study has nonetheless uncovered a key mechanism by which sleep enhances neuronal and behavioral performance, potentially changing our fundamental understanding of how sleep boosts brainpower.

A new study reveals a troubling rise in severe maternal health issues and birth complications in Illinois from 2016 to 2023, closely linked to increases in chronic health conditions affecting pregnancy, such as high blood pressure, gestational diabetes, mental health disorders and especially obesity, which saw the largest increase in annual rates.

Working with week-old zebrafish larva, researchers decoded how the connections formed by a network of neurons in the brainstem guide the fishes' gaze. The study found that a simplified artificial circuit, based on the architecture of this neuronal system, can predict activity in the network. In addition to shedding light on how the brain handles short-term memory, the findings could lead to novel approaches for treating eye movement disorders. Read more ›

A new study found that prolonged standing at work had a negative impact on the research participants' 24-hour blood pressure. In contrast, spending more time sitting at work was associated with better blood pressure. The study suggests that activity behavior during working hours may be more relevant to 24-hour blood pressure than recreational physical activity. Read more ›

Engineers have cooked up a new way to improve mRNA delivery, developing an optimal 'recipe' for ionizable lipids -- key ingredients in lipid nanoparticles (LNPs), the molecules behind the COVID-19 vaccines and other innovative therapies. The method mirrors the iterative process of developing a culinary dish and may lead to safer, more effective mRNA vaccines and therapeutics. Read more ›

A research team has developed a new class of oral peptide therapeutic leads for treating chronic abdominal pain. This groundbreaking innovation offers a safe, non-opioid-based solution for conditions such as irritable bowel syndrome (IBS) and inflammatory bowel diseases (IBD), which affect millions of people worldwide.

Some sequences in the genome cause genes to be switched on or off. Until now, each of these gene switches, or so-called enhancers, was thought to have its own place on the DNA. Different enhancers are therefore separated from each other, even if they control the same gene, and switch it on in different parts of the body. A recent study challenges this idea. The findings are also important because... Read more ›

A massive collision of galaxies sparked by one travelling at a scarcely-believable 2 million mph (3.2 million km/h) has been seen in unprecedented detail by one of Earth's most powerful telescopes. The dramatic impact was observed in Stephan's Quintet, a nearby galaxy group made up of five galaxies first sighted almost 150 years ago. It sparked an immensely powerful shock akin to a 'sonic boom from a jet fighter' --... Read more ›

Researchers have analyzed the entire mouse intestine, mapping gene expression and cell states and location in the healthy gut and in response to perturbations such as inflammation. They identified tight regulation of cell types and states in different regions of the organ, as well as a unique segment of the colon that is controlled by immune signals. The findings reveal the surprising adaptability and resilience of the intestine to perturbations... Read more ›

Adolescents who snore frequently were more likely to exhibit behavior problems such as inattention, rule-breaking, and aggression, but they do not have any decline in their cognitive abilities, according to a new study. This is the largest study to date tracking snoring in children from elementary school through their mid-teen years and it provides an important update to parents struggling with what medical measures to take to help manage snoring...

A new study shows that the oceans were less cold in the early 20th century (1900--1930) than previously thought. During this period the ocean appears too cold due to the way some measurements were taken. This makes global ocean surface temperature measurements during this period inconsistent with both land air temperatures and palaeoclimatic data and the differences between land and ocean are larger than shown in climate models.
