Children trust what they hear over what they see, study finds‎

New research from our Department of Psychology has revealed that children are far more likely than adults to judge a person's emotions by what they hear rather than what they see.

Bubbles the food-stealing dolphin finds shortcut to easy meal‎

Invasive little fire ants prefer cooked beef, seeds over tuna‎

If you are trying to detect or bait little fire ants in your backyard, scientists at the University of Hawaiʻi at Mānoa suggest swapping tuna for cooked beef and sunflower seeds. The study, published in the Journal of Applied Entomology by researchers at the UH Mānoa College of Tropical Agriculture and Human Resilience (CTAHR), revealed that the little fire ant's (Wasmannia auropunctata) preferred diet is not what scientists and homeowners previously thought. In laboratory food-choice tests, the tiny, stinging pests overwhelmingly chose cooked beef and sunflower seeds over water-packed tuna.

Robots and AI uncover unexpected pathway in classic 135-year-old chemical reaction‎

Chemical reactions are often written as simple equations: Starting materials go in, and a product comes out. In reality, the same substrates can follow many different pathways depending on their concentrations, temperature, catalysts and other conditions.

Novel particle beam could challenge Einstein's theory of gravity‎

Does gravity act equally on all particles in the universe, or are there differences between ordinary and exotic matter? Physics professor Anna Soter and her team at ETH Zurich and the Paul Scherrer Institute (PSI) in Villigen are investigating this question. "We have taken an important step toward carrying out an exciting experiment on this topic," says Soter. "We want to measure the gravitational interaction of the muon."

Young European shags reveal how first winter experiences may guide migration‎

Should I stay or should I go? What determines whether birds migrate for the winter? This is one of the questions explored in a new doctoral thesis by Cassandra Ugland from NTNU's Department of Biology. The work is published in the Journal of Animal Ecology.

'HyperBird' imaging platform spots grape diseases before they're visible‎

HyperBird, a cutting-edge imaging platform for observing microscopic traits in plants, can detect grape diseases—such as powdery and downy mildews, which cost vineyard owners billions in annual losses globally—days before physical symptoms become visible. The advancement could allow plant breeders to speed the development of disease-resistant grape varieties, cue growers to target fungicide use early in a disease's progression and provide vineyard workers with better, earlier information for crop management.

Small farming management changes could help protect birds under threat‎

New research from the University of Aberdeen and Edinburgh Napier University has found that simple changes to the timing of conservation measures on farmland could significantly improve protection for some of the U.K.'s most rapidly declining wading bird species.

For many group-living females, breeding and raising young are shared endeavors‎

Some female animals living in groups raise offspring that are not their own, sometimes without reproducing themselves. While the behavior of cooperatively breeding species is well documented, some aspects remain poorly understood.
