Drummers in west Africa who play hourglass-shaped percussion instruments called dùndúns can make their instrument not only sing, but talk. New research published in the journal Frontiers in Communication is one of the first to show the high degree of acoustic correlation between these talking drums and the spoken Yorùbá language.

On Aug. 26, 2020, NASA’s Fermi Gamma-ray Space Telescope detected a pulse of high-energy radiation that had been racing toward Earth for nearly half the present age of the universe. Lasting only about a second, it turned out to be one for the record books—the shortest gamma-ray burst (GRB) caused by the death of a massive star ever seen.

- Now in 3D: Deep learning techniques help visualize X-ray data in three dimensionson July 26, 2021 at 6:13 pm
Computers have been able to quickly process 2D images for some time. Your cell phone can snap digital photographs and manipulate them in a number of ways. Much more difficult, however, is processing an image in three dimensions, and doing it in a timely manner. The mathematics are more complex, and crunching those numbers, even on a supercomputer, takes time.

- Scientists discover how high-energy electrons strengthen magnetic fieldson July 26, 2021 at 4:43 pm
More than 99% of the visible universe exists in a superheated state known as plasma—an ionized gas of electrons and ions. The motion of these charged particles produces magnetic fields that form an interstellar magnetic web. These magnetic fields are important for a wide range of processes, from the shaping of galaxies and the formation of stars to controlling the motion and acceleration of high-energy particles like cosmic rays—protons and electrons that zoom through the universe at nearly the speed of light.
- How crushed rocks can help capture carbon dioxideon July 26, 2021 at 4:43 pm
IIASA researchers and international colleagues explored the potential of using finely ground rock to help with the removal of CO2 from the atmosphere on the road to achieving net-zero emissions and keeping global warming below 1.5°C.
- New methane concentration technologies for monitoring greenhouse gas emissionson July 26, 2021 at 4:42 pm
Methane concentrations in the atmosphere have more than doubled over the last 150 years and mitigation of methane emissions will play a vital role in enabling climate change mitigation strategies. Understanding current and future methane inventories at a regional scale will be a key element in developing and implementing successful solutions. Current regional scale isotopic methane data is not available at a high enough frequency to enable comparison to the models that are used to derive national emission estimates. In order to improve these current data sets, more in-situ measurements of methane isotopic data are required and current techniques do not provide the required sensitivity and frequency.
