Consumers willing to pay more for lobster harvested with ropeless technology, study finds‎

U.S. consumers are willing to pay more for lobster harvested using ropeless fishing technology designed to reduce whale entanglement risks, according to new University of Maine research. A study led by Qiujie "Angie" Zheng, associate professor of business analytics in the University of Maine's Maine Business School, found that consumers are willing to pay an average of $3.42 more for a lobster roll made with lobster harvested using ropeless fishing technology when presented with information on animal welfare.

Hidden small RNA in cholera bacterium helps determine whether it can infect humans‎

Scientists from St. Jude Children's Research Hospital have uncovered what gives Vibrio cholerae, the bacterium that causes cholera, the ability to colonize the human gut. The researchers found that a small RNA embedded within another gene controls where cholera thrives, a discovery that could improve prediction and prevention strategies. The study is published in the journal Nature Communications.

First outbursting hot subdwarf binary discovered‎

An international team of astronomers has utilized the Zwicky Transient Facility (ZTF) and the Transiting Exoplanet Survey Satellite (TESS) to investigate a binary system designated ZTF J0007+4804. As a result, they have found that ZTF J0007+4804 is the first hot subdwarf-white dwarf system discovered that produces dwarf nova outbursts. The finding is reported in a paper published May 4 on the arXiv preprint server.

Why some water fleas suddenly grow helmets: Key receptors reveal how predator warnings trigger defense‎

Daphnia, commonly known as water fleas, are tiny crustaceans that live in freshwater ponds and lakes. When they sense predators in their surroundings, these small organisms can swiftly move away or adapt their body shape, for instance becoming rounder and forming large helmets or spines on their head, neck or tail.
