Is the 'love hormone,' oxytocin, also the 'friendship hormone'?
2025-08-11
A new UC Berkeley study shows that the so-called love hormone, oxytocin, is also critical for the formation of friendships.
Oxytocin is released in the brain during sex, childbirth, breastfeeding and social interactions and contributes to feelings of attachment, closeness and trust. Never mind that it’s also associated with aggression; the hormone is commonly referred to as the "cuddle" or "happy" hormone, and people are encouraged to boost their oxytocin levels for better well-being by touching friends and loved ones, listening to music and exercising.
But recent studies involving the prairie vole have ...

To help manage agricultural practices with fewer or no pesticides, University of Michigan researchers say they need to understand how ecological systems work on agricultural lands.
Now, U-M researchers John Vandermeer and Ivette Perfecto have used two ecological theories to describe a tangle of interactions between three ant species and a recently introduced fly that preys on one of the ant species. Their work on a coffee farm in Puerto Rico shows that the interaction between the ants and the predator fly creates chaotic patterns—chaos in ...
Planets without water could still produce certain liquids, a new study finds
2025-08-11
Water is essential for life on Earth. So, the liquid must be a requirement for life on other worlds. For decades, scientists’ definition of habitability on other planets has rested on this assumption.
But what makes some planets habitable might have very little to do with water. In fact, an entirely different type of liquid could conceivably support life in worlds where water can barely exist. That’s a possibility that MIT scientists raise in a study appearing this week in the Proceedings of the National Academy of Sciences.
From lab experiments, the researchers found that a type of fluid known as an ionic liquid can readily ...
Researchers identify key biomarkers for chronic fatigue syndrome
2025-08-11
ITHACA, N.Y. – When cells expire, they leave behind an activity log of sorts: RNA expelled into blood plasma that reveal changes in gene expression, cellular signaling, tissue injury and other biological processes.
Cornell University researchers developed machine-learning models that can sift through this cell-free RNA and identify key biomarkers for myalgic encephalomyelitis, also known as chronic fatigue syndrome (ME/CFS). The approach could lead to the development of diagnostic testing for a debilitating disease that has proved challenging ...

Lab-made sugar-coated particle blocks Covid-19 infection — Possible new treatment on the horizon
2025-08-11
Groundbreaking research led by a Swansea University academic has revealed a synthetic glycosystem — a sugar-coated polymer nanoparticle — that can block Covid-19 from infecting human cells, reducing infection rates by nearly 99%.
The glycosystem is a specially designed particle that mimics natural sugars found on human cells. These sugars, known as polysialosides, are made of repeating units of sialic acid — structures that viruses often target to begin infection. By copying this structure, the synthetic molecule acts as a decoy, binding to the virus’s spike protein and preventing it from attaching to real cells.
Unlike vaccines, which trigger immune responses, ...

By promising a faster and cheaper way to quality control graphene oxide, the scientists ...
How organic matter traps water in soil — even in the driest conditions
2025-08-11
From lifelong farmers to backyard gardeners, most plant-lovers know that adding organic matter to a field, vegetable plot or flowerpot increases the soil’s moisture.
Now, for the first time, Northwestern University scientists have uncovered the molecular mechanisms that enable organic matter to boost soil’s ability to retain water — even in desert-like conditions.
Carbohydrates — key components of plants and microbes — act like a molecular glue, using water to form sticky bridges between organic molecules and soil minerals, the team found. These bridges lock in moisture that ...

Researchers unlock safer RNA therapies for inflammatory diseases
2025-08-11
PHILADELPHIA – Lipid nanoparticles (LNPs) are tiny fat bubbles that are used to deliver medicines, genes, and RNA into cells. However, in some cases LNPs can cause harmful inflammation as a result of the process of RNA delivery. Now, two new solutions can help alleviate inflammation while still getting RNA where it needs to be in the cell. One discovery found that inflammation could be reduced with the addition of a unique biodegradable lipid to the treatment; another solution identified a common drug, called thiodigalactoside (TG), which blocked inflammation when added to the LNP. Today’s Nature Nanotechnology features this research from the Perelman ...

Why oxytocin treatments for social behavior are inconsistent
2025-08-11
Oxytocin promotes social behaviors and helps maintain relationships. But clinical trials in patients with autism show variability in how consistently oxytocin improves these behaviors. Steve Chang, from Yale University, led a study to explore how oxytocin influences brain activity to shape social behavior in rhesus monkeys and why its effects are so variable. This work is featured in JNeurosci’s Central Questions for Social Neuroscience Research Special Collection.
The researchers focused on the basolateral amygdala (BLA) and the anterior cingulate cortex (ACC) because these brain areas process reward and integrate ...

In utero brain surgery for Vein of Galen Malformation shows continued promise in new JAMA report
2025-08-11
Building upon the success of the first in utero brain surgery for Vein of Galen Malformation (VOGM) reported in 2023, new data published today in JAMA provides further evidence for the potential use of fetal embolization for this condition.
VOGM is the most common type of congenital blood vessel abnormality, in which the earliest arteries that develop in the brain connect directly with the dominant vein in the young brain, rather than nourishing the brain tissue. This causes a tremendous rush of high-pressure, high-flow blood into the veins, putting the fetus at high risk for mortality, heart failure, brain ...

GLP-1 receptor agonists and sight-threatening ophthalmic complications in patients with type 2 diabetes
2025-08-11
About The Study: In this cohort study of individuals with type 2 diabetes (T2D), glucagon-like peptide-1 receptor agonist (GLP-1 RA) use was associated with a modestly increased risk of incident diabetic retinopathy (DR); however, fewer patients experienced sight-threatening DR complications, including blindness, even among those with preexisting DR. These findings suggest that all patients with T2D treated with GLP-1 RAs, regardless of preexisting DR, should be regularly screened and monitored for potential complications of T2D.
