Video interview with AHA volunteer expert: Dan Roden, M.D., FAHA, chair of the American Heart Association’s Council on Genomic and Precision Medicine and professor of medicine, pharmacology and biomedical informatics and senior vice-president for personalized medicine at Vanderbilt University Medical Center in Nashville.
This animated graph displays the frequency and signal strength of gravitational waves using a simulated dataset of galactic ultracompact binaries. The colors on the graph indicate frequencies ranging from about 0.001 to 0.01 hertz, with lighter colors representing higher frequencies. The dashed curve shows the expected sensitivity limit of the LISA (Laser Interferometer Space Antenna) mission, which is currently being designed by the ESA (European Space Agency) in collaboration with NASA for launch in the 2030s.

The findings are featured on the cover of the journal Cancer Cell • The authors of the study, from the Spanish National Research Council (CSIC) and the Spanish National Cancer Research Centre (CNIO), suggest that cognitive loss in patients with brain metastases may be due to the interference that cancer produces in neuronal circuits. • When cancer spreads in the brain, it changes the brain’s chemistry, interfering with the communication between neurons. This is a very different hypothesis from the one previously accepted, with implications for the diagnosis and treatment of brain metastases. © Atlas / CNIO
Northwestern astrophysicists developed the first numerical simulation that follows the jet evolution in a black hole-neutron star merger out to large distances. Using this model, the researchers discovered that the post-merger black hole can launch jets of material from the swallowed neutron star. Credit: Ore Gottlieb/Danat Issa/Alexander Tchekhovskoy
