How intermittent feedback drives consumer impatience

Researchers from Fudan University's School of Management have published a new paper in the Journal of Consumer Psychology that provides original insights about the impact different types of feedback consumers have on consumers' psychological state.

Study: Allowing financial trading in California's wholesale electricity market significantly reduces volatility

Forward markets—over-the-counter marketplaces that set the price of a financial instrument or asset—are used to trade a variety of instruments, including securities and commodities. In a new study, researchers measured the extent to which forward prices and spot prices (the current market price at which a given asset can be bought or sold for immediate delivery) agreed in markets with...

Sexing chicken eggs by scent

Fertilized chicken eggs can be sexed by "sniffing" volatile chemicals emitted through the shell, according to new work by researchers at the University of California, Davis, and Sensit Ventures Inc., a startup company in Davis. The work is published May 22 in PLOS ONE.

Study points out errors in illustrations of one of the most famous scientific experiments

Illustrations of scientific experiments play a fundamental role in both science education and the dissemination of scientific knowledge to the general public. Confirming the adage that "a picture is worth a thousand words," these depictions of famous experiments remain in the minds of those who study them and become definitive versions of the scientific process. Archimedes in the bath discovering...

First contact: Global team to simulate message from extraterrestrial intelligence to Earth

What would happen if we received a message from an extraterrestrial civilization? Daniela de Paulis, an established interdisciplinary artist and licensed radio operator who currently serves as Artist in Residence at the SETI Institute and the Green Bank Observatory, has brought together a team of international experts, including SETI researchers, space scientists, and artists, to stage her latest...

In-situ observations of marine sedimentary rocks suggest ancient northern ocean on Mars

An international research team led by Professor Long Xiao from the School of Earth Sciences of China University of Geosciences (Wuhan) has discovered the presence of marine sedimentary rocks on the surface of Mars for the first time by comprehensively analyzing the scientific data obtained by the multispectral camera (MSCam) carried by the Zhurong rover. The relevant research results were...

Scientists discover nonlocal effects of biexciton emission in large semiconductor nanocrystals

In a new paper published in eLight, a team of scientists led by Professors Haizheng Zhong and Yongyou Zhang from the Beijing Institute of Technology and Professor Haiyan Qin from Zhejiang University have discovered nonlocal effects in large semiconductor nanocrystals. They provide new strategies to achieve high-efficiency multiple excitons for quantum optics and energy conversation applications.

Researchers review AI advantages in drug research and development

Scientists have long been challenged by the complex process of drug discovery and development, with investments that often go unrewarded. However, with the advancement of experimental technology and computer hardware, artificial intelligence (AI) has emerged as a leading tool in analyzing abundant and high-dimensional data.

Q&A: Researcher discusses a new model of nervous system form, function, and evolution

How does animal behavior emerge from networks of connected neurons? How are these incredible nervous systems and behaviors actually generated by evolution? Are there principles shared by all nervous systems or is evolution constantly innovating? What did the first nervous system look like that gave rise to the incredible diversity of life that we see around us?

Lab-grown meat's carbon footprint potentially worse than retail beef, finds study

Lab-grown meat, which is cultured from animal cells, is often thought to be more environmentally friendly than beef because it's predicted to need less land, water and greenhouse gases than raising cattle. But in a preprint, not yet peer-reviewed, researchers at the University of California, Davis, have found that lab-grown or "cultivated" meat's environmental impact is likely to be "orders of...

Ozone treaty is delaying first ice-free Arctic summer, shows study

A 1987 global deal to protect the ozone layer is delaying the first ice-free Arctic summer by up to 15 years, new research shows. The paper, published in the journal Proceedings of the National Academy of Sciences, is entitled "The Montreal Protocol is delaying the occurrence of the first ice-free Arctic summer."
