For the first time, an HZB team has derived analytically how corkscrew-shaped nano-antennas interact with light. The mathematical tool can be used to calculate the geometry that a nano-antenna must have for specific applications in sensor technology or information technology.
By combining cutting-edge machine learning with 19th-century mathematics, a Worcester Polytechnic Institute (WPI) mathematician is working to make NASA spacecraft lighter and more damage tolerant by developing methods to detect imperfections in carbon nanomaterials used to make composite rocket fuel tanks and other spacecraft structures.
It is among the most spectacular events in the universe: a merger of neutron stars. An international team of researchers with strong representation from the Technical University of Munich (TUM) has completed the first laboratory measurements of thermal electromagnetic radiation arising in such collisions. The resulting data enabled them to calculate the prevailing temperature when such stars merge.
A team of neuroscientists at the University of Tuebingen and MIT's Picower Institute for Learning and Memory shows how to distinguish four classes of brain cells by their spike waveforms. The advance offers brain researchers the chance to better understand how different kinds of neurons are contributing to behavior, perception and memory, and how they are malfunctioning in cases of psychiatric or neurological diseases.
Researchers at the George Washington University have developed a mapping model, the first of its kind, to track how hate spreads online.
Researchers from the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) have developed a mathematical framework that can turn any sheet of material into any prescribed shape, inspired by the paper craft termed kirigami (from the Japanese, kiri, meaning to cut and kami, meaning paper).
Should hospital advertising be banned? A few policymakers in Washington, D.C., have recently considered such an action based on a long-standing debate on whether it poses the spread of misinformation, and that it is not an effective or responsible use of an already limited healthcare budget. New research in the INFORMS journal Marketing Science studies the impact of a ban on hospital advertising, and whether those fears are justified.
In the blink of an eye, the human visual system can process an object, determining whether it's a cup or a sock within milliseconds, and with seemingly little effort. It's well-established that an object's shape is a critical visual cue to help the eyes and brain perform this trick. A new study, however, finds that while the outer shape of an object is important for rapid recognition, the object's inner 'skeleton' may play an even more important role.
UC Berkeley neuroscientists have created interactive maps that can predict where different categories of words activate the brain. Their latest map is focused on what happens in the brain when you read stories.
Detrimental economic effects of global warming are likely to go beyond those being discussed in policy circles -- particularly for wealthier nations, say researchers. Study suggests that 7% of global GDP will disappear by 2100 as a result of business-as-usual carbon emissions -- including over 10% of incomes in both Canada and the United States.
