Experiments at BESSY II show that during electrolysis, the structure breaks down into ultrathin nickel sheets, exposing the active catalytic centers to the electrolyte. Hydrogen can be produced through the electrolysis of water. When the electricity for this process comes from renewable sources.
Google has uncovered a vishing campaign by UNC6040 targeting Salesforce users through fake Data Loader apps.
Halbers et al. present a useful tool — a way of accurately tracking RNAs that only requires a small addition to a given RNA sequence and leverages modified split luciferase proteins for bioluminescent photon emission, circumventing some drawbacks of fluorescent methods.
Studying RNA dynamics in vivo often relies on fluorogenic approaches, but these can be hampered by factors such as limited sensitivity and sample autofluorescence. Here, the authors describe an ultrasensitive platform for RNA imaging, which features RNA tags that recruit light-emitting luciferase fragments.
We tested whether chimpanzees and children are more curious about social interactions versus a single agent (Experiment 1), whether they are willing to pay a cost to gain social information (Experiment 2), and whether they are more curious about positive or negative social interactions (Experiment 3). Combined, we found that both chimpanzees and children are socially curious creatures. Chimpanzees and children are more curious about social interactions than the actions of a single conspecific, young children and male chimpanzees are willing to pay a cost to gain social information, and boys become more curious about negative social interactions while girls become more curious about positive social interactions as they develop.
In Experiment 1, chimpanzees and children are significantly more motivated to watch videos of social interactions compared with videos of a conspecific acting alone. Children are also significantly more likely to open the social box compared with the nonsocial box, and trend towards opening the door of the social box wider. What is driving this effect? One option is that chimpanzees and children possess a specific drive to gain information about social interactions. Another option is information quantity: a social interaction between two agents naturally contains more information than does a single agent acting alone, as the interaction provides information not only about the two actors but also about the nature of their relationship. Therefore, children and chimpanzees might show stronger curiosity for social interactions compared with individual agents to gain more information.

Using advanced electron crystallography techniques, researchers at Stockholm University have succeeded in determining the structure of the historically significant red pigment carmine. It turns out that the substance, used today in products such as candy and paint, has a complex porous structure.
The study is published in the journal Crystal Growth & Design.
Carmine is a natural red coloring agent produced from cochineal extract. The extract from these insects is rich in carminic acid, which is combined with aluminum (Al) and calcium (Ca) to produce carmine. Analysis using advanced electron microscopy techniques has now revealed that this pigment has an unexpected structure. It is a so-called metal complex, built from two calcium ions, two aluminum ions, and four organic ligand molecules of carminic acid.
