Cloud Services Without Servers: What’s behind it

A new generation of cloud services is on the rise. It is based on the paradigm of ‘serverless computing’. A recent article deals with the history, status and potential of serverless computing.

In cloud computing, commercial providers make computing resources available on demand to their customers over the Internet. This service is partly offered “serverless,” that is, without servers. How can that work? Computing resources without a server, isn’t that like a restaurant without a kitchen?

“The term is misleading,” says computer science Professor Samuel Kounev from Julius-Maximilians-Universität (JM...

Carbon Source found on Surface of Jupiter’s Moon Europa

Astronomers using data from NASA’s James Webb Space Telescope have identified carbon dioxide in a specific region on the icy surface of Europa.

Jupiter’s moon Europa is one of a handful of worlds in our solar system that could potentially harbor conditions suitable for life. Previous research has shown that beneath its water-ice crust lies a salty ocean of liquid water with a rocky seafloor. However, planetary scientists had not confirmed if that ocean contained the chemicals needed for life, particularly carbon.

Study finds Dopamine Regulates How Quickly and Accurately Decisions are made

Dopamine regulates how quickly and accurately decisions are made
Behavioral data. Response time (RT) distributions (n = 31, within-subject design) under Placebo (a), L-dopa (b), and Haloperidol (c). Choices of the suboptimal (20% reinforced) options in (a–c) are coded as negative RTs, whereas choices of the optimal (80% reinforced) options are coded as positive RTs. d Accuracy per drug condition (chance level is 0.5). e Total rewards earned per condition. f Median RT per drug condition. Pl – Placebo, L – L-dopa, H – Haloperidol. For boxplots, lines represent the median, the box covers the upper and lower quartiles, and the whiskers denote the range of datapoints falling within 1.5 times the interquartile range.

Researchers have determined how to build reliable machine learning models that can understand complex equations in real-world situations while using far less training data than is normally expected.

The researchers, from the University of Cambridge and Cornell University, found that for partial differential equations—a class of physics equations that describe how things in the natural world evolve in space and time—machine learning models can produce reliable results even when they are provided with limited data.

Their results, reported in the Proceedings of the National Academy of Sciences, could be useful for constructing more t...
