In 2005, a research team led by University of Zurich economics professor Ernst Fehr published a study in the journal Nature that provided evidence for the first time that intranasally administered oxytocin can increase trusting behavior in humans. Oxytocin is a hormone and neurotransmitter produced naturally in the body that influences social interactions, among other things.

Food and pharmaceutical manufacturers increasingly seek lipids with carefully controlled fatty-acid compositions. However, natural oils usually contain mixtures of closely related fatty acids, and conventional enzymes often cannot distinguish reliably between them.

Whether it's neurons responding to electrical signals or plants stretching toward light, nature is filled with examples of biological materials that respond to their environment. Now, researchers want to develop new responsive materials for a wide range of applications, such as sensing or low-energy technologies. However, achieving a balance of useful properties at the molecular level is challenging.

Modern biomedicine increasingly relies on enormous amounts of image data. Although computers can do part of the analysis work, biologists often still need to look through the images themselves. This takes time.

For more than two decades, the quasar PHL 1811 has been considered the prototype of a rare class of "intrinsically X-ray weak" quasars, thought to produce unusually little X-ray radiation. But in 2024, the Einstein Probe spacecraft caught the object in a bright X-ray flare. In a new study, astronomers combined that observation with more than 20 years of archival data to revisit the mystery. The findings were published in The Astrophysical Journal on July 28.

Fourth-year veterinary students matched—and experienced clinicians outperformed—an AI-enabled digital stethoscope in diagnosing heart murmurs and arrhythmias in cats and dogs, according to a new study from North Carolina State University. The study emphasizes the importance of human expertise when using AI-assisted technology, particularly with instruments designed for "universal" usage. The research is published in the Journal of the American Veterinary Medical Association.

University of Bristol–led researchers have identified a naturally occurring gut molecule that could strengthen chickens' immune response against a wide range of bacterial infections. This development, published today, Aug. 12, in The Journal of Immunology, offers a major step forward in sustainable farming and the global fight against antibiotic resistance.

Signals ride on waves of one kind or another: light, sound, radio. But new carriers are needed to relay information in next-generation devices. Disturbances or waves in magnetic materials called magnons could be an efficient option—if scientists can tame them.

Place-based decarbonization schemes designed to help communities become more sustainable must involve local people earlier and consider the range of different community responses in their development if they are to be successful and gain fuller community support, researchers have said. Countries worldwide are exploring a range of ways to transition to low-carbon energy systems to reduce carbon emissions and increase energy security, including different place-based approaches that take the social and technical characteristics of a place into consideration in their design.

Most people underestimate how much light a pair of sunglasses blocks out. A typical dark pair removes around 80% to 90% of the visible light reaching the eye.

The use of nanoparticles in drug delivery offers key advantages: they can enable targeted drug delivery, protect active ingredients from premature degradation, extend their duration of action in the body and reduce side effects. However, as soon as nanoparticles come into contact with blood, proteins from the blood adsorb onto their surface—forming a so-called protein corona. This corona influences whether the particles are taken up by cells, how they distribute in the body or whether the immune system recognizes and attacks them.

Before tropical cyclones can significantly strengthen, they generally must first become vertically aligned, with their rotating centers stacked through the atmosphere. New research using nearly three decades of NOAA Hurricane Hunter observations identifies four features that can help a tilted storm become aligned and more capable of intensifying.

River and canal ships generate roughly a quarter of the world's shipping carbon dioxide emissions, according to new research published in Nature Climate Change. And that's despite the fact that these bodies of water make up less than 1% of Earth's total navigable waterways.

From the American West to Europe, droughts are drying up rivers, fueling destructive fires and reshaping ecosystems. They are also changing the spread of infectious diseases, leading to surges in illnesses like cholera and West Nile virus around the world.
