Cephalopod Passes Cognitive Test Designed For Human Children
mi shares a report from ScienceAlert: The marshmallow test, or Stanford marshmallow experiment, is pretty straightforward. A child is placed in a room with a marshmallow. They are told, if they can manage not to eat the marshmallow for 15 minutes, they’ll get a second marshmallow, and be allowed to eat both. This ability to delay gratification demonstrates cognitive abilities such…
China Charges Ahead With a National Digital Currency
The electronic Chinese yuan is now being tested in cities such as Shenzhen, Shanghai and Beijing. No other major power is as far along with a homegrown digital currency. From a report: Annabelle Huang recently won a government lottery to try China’s latest economics experiment: a national digital currency. After joining the lottery through the social media app WeChat, Ms. Huang,…
International Space Station archives fuel new scientific discoveries
When scientists complete an experiment aboard the International Space Station, the ramifications of that work have just begun. NASA carries on a legacy of decades of biological research data, fueling new discoveries long after studies wrap up in space.

The hunt for the quantum collapse
The most famous cat in science is Schrödinger’s cat, the quantum mechanical mammal, which can exist in a superposition, a state that is alive as well as dead. The moment you look at it, one of both options is chosen. Leiden University physicists simulated an experiment to catch this mysterious moment of choice red handed. …

Twitter’s Misinformation-Fighting Tool ‘Birdwatch’ Makes Mistakes
The Poynter Institute for Media Studies, a non-profit journalism school and research organization, analyzed Twitter’s 1,000-user pilot test of its Birdwatch fact-checking platform. Their conclusion? It makes mistakes. On February 5, Twitter flagged a post from controversial YouTuber Tim Pool that said the 2020 U.S. presidential election was rigged. The platform noted that the claim was disputed and turned off engagement…

Investigating the wave properties of matter with vibrating molecules
The working group led by Prof. Stephan Schiller, Ph.D. from Heinrich Heine University Düsseldorf (HHU) has used a novel, high-precision laser spectroscopic experiment to measure the internal vibration of the simplest molecule. This allowed the researchers to investigate the wave character of the motion of atomic nuclei with unprecedented accuracy. They present their findings in the current edition of Nature Physics….
A new planet next door?
Astronomers have spotted “something” near Alpha Centauri A, in the star system nearest our Earth and sun. If it turns out to be a planet, it’ll be the first time a planet has been directly imaged within the habitable zone of a star.
