Co-invented by Kristian Hammond, co-director of Northwestern's Intelligent Information Laboratory (InfoLab), and graduate students Nathan Nichols and Sara Owsley, "News at Seven" collects, edits and organizes existing news stories based on a user's interests, then passes the formatted content to the virtual anchor. Using Web resources like Google and YouTube, the system utilizes the text of news stories to retrieve video, images and blogs related to the content of the story.
"It's a completely personalized, completely automated news report using Web resources," explains Hammond, professor of electrical engineering and computer science at Northwestern's McCormick School of Engineering and Applied Science. "The system can create an original news package based on someone's interest, then deliver it on demand. It is the first step in creating a world in which information is automatically gathered, edited and delivered to people based on their interests and needs."
Once it has assembled the materials, the system edits the news stories, replacing abbreviations and other phrasings that are appropriate for written text but not meant to be spoken. News at Seven virtual anchors then present a cohesive, compelling performance that combines techniques of modern news programming with features made possible by the fact that the system is, at its core, completely virtual.
In this first version of the system, News at Seven produces a three-minute daily news update, featuring national, international and human-interest stories. Information from blogs provides commentary on national stories.
Although a very young project, News at Seven already creates a compelling, cohesive, on-topic newscast. With further research and development, the creators of News at Seven hope to offer a commercially viable replacement to the typical televised news show, offering instead a show tailored to a user's specific interests. A brand new news package could be delivered daily, hourly or even every half hour.

Plants and algae use the enzyme Rubisco to fix carbon dioxide, removing it from the atmosphere and converting it into biomass. Algae have figured out a way to increase the efficiency of carbon fixation. They gather most of their Rubisco into a ball-shaped microcompartment called the pyrenoid, which they flood with a high local concentration of carbon dioxide. A team of scientists at Princeton University, the Carnegie Institution for Science, Stanford University and the Max Plank Institute of Biochemistry have unravelled the mysteries of how the pyrenoid is assembled. These insights can help to engineer crops that remove more carbon dioxide from the atmosphere while producing more food.

Our brains house extremely complex neuronal circuits, whose detailed structures are still largely unknown. This is especially true for the so-called cerebral cortex of mammals, where among other things vision, thoughts or spatial orientation are being computed. Here the rules by which nerve cells are connected to each other are only partly understood. A team of scientists around Moritz Helmstaedter at the Frankfiurt Max Planck Institute for Brain Research and Helene Schmidt (Humboldt University in Berlin) have now discovered a surprisingly precise nerve cell connectivity pattern in the part of the cerebral cortex that is responsible for orienting the individual animal or human in space.
The researchers report online in Nature (Schmidt et al., 2017. Axonal synapse sorting in medial entorhinal cortex, DOI: 10.1038/nature24005) that synapses in...

Using ultrafast flashes of laser and x-ray radiation, scientists at the Max Planck Institute of Quantum Optics (Garching, Germany) took snapshots of the briefest electron motion inside a solid material to date. The electron motion lasted only 750 billionths of the billionth of a second before it fainted, setting a new record of human capability to capture ultrafast processes inside solids!
When x-rays shine onto solid materials or large molecules, an electron is pushed away from its original place near the nucleus of the atom, leaving a hole...
For the first time, physicists have successfully imaged spiral magnetic ordering in a multiferroic material. These materials are considered highly promising candidates for future data storage media. The researchers were able to prove their findings using unique quantum sensors that were developed at Basel University and that can analyze electromagnetic fields on the nanometer scale. The results – obtained by scientists from the University of Basel’s Department of Physics, the Swiss Nanoscience Institute, the University of Montpellier and several laboratories from University Paris-Saclay – were recently published in the journal Nature.
Multiferroics are materials that simultaneously react to electric and magnetic fields. These two properties are rarely found together, and their combined...
