ONCE A MONTH MERGERS. “With this new discovery of neutron star-black hole mergers outside our galaxy, we have found the missing type of binary. We can finally begin to understand how many of these systems exist, how often they merge, and why we have not yet seen examples in the Milky Way.” The researchers believe that one of these violent mergers occurs about once a month within a billion light-years of Earth.“ https://www.cnn.com/2021/06/29/world/black-hole-neutron-star-merger-scn/index.html View in LinkedIn

EXAPTATION. “Evolution works best when it does not need to generate a whole new active site from scratch. Instead, evolution can generate a new enzyme from one that is “close”, that is, shares elements of mechanism or machinery from which the new activity can be built. Nature co-opts old machinery to do new jobs.” https://lnkd.in/d2-p85M View in LinkedIn

LUMINOSITY AND GROWTH. “Various observational studies suggest that moderately luminous AGN are typically not major-merger driven, at z < 1, and interestingly also at z ≈ 2 as they do not find more morphological distortions for AGN host galaxies than for inactive galaxies.” (AGN = active galactic nuclei). https://lnkd.in/d9JV8md View in LinkedIn

THE FAILURE OF THE SMALL. “As an implicit consequence of massive black hole seeds, we have also assumed that seeds are not able to form in dark matter haloes below 2 × 10(11) M⊙, as cold gas might not be able to collapse in these haloes due to their shallow potential wells. This simultaneously reduces the number of faint AGN at high redshift, in better agreement with observations.” (AGN = active galactic nuclei; M⊙ = solar masses). https://lnkd.in/d9JV8md View in LinkedIn

EDUCATION IS BROKEN. “Synthesis is a simulation-based learning experience built around complex team games. Students work through case studies, simulations, and game-based challenges. While playing, kids teach themselves how to win. In the process, they learn new problem-solving skills.” Batch students by ability not age, teach the problem not the tool. https://lnkd.in/dP5rMwf View in LinkedIn
